Space Migration: Anthropology and Future of Humanization of Space

0

Space humanization seems just a few steps away. The human race is now technologically advanced to find themselves out of the Earth’s layers and into space, stepping on the Moon, living in orbit, and working to develop a habitat on Mars. We finally are in the era where we are looking deep further into the ocean of stars and galaxies way beyond from own solar system and galaxy.

We can look back in time and track the future based on it. Looking to take the leap of faith by looping onto the exoplanets and discussing migrating into extraterrestrial zones. Anthropology seems to be a crucial part of understanding, facilitating, and unleashing the process of future outer space human civilization.

Many cultures throughout history have migrated from their native habitats into an unknown world. Biological advancement has also evolved the cultural analogies of the human race. Anthropology seems to have contributed less to our technical and futuristic originality as escalating into space. The idea of space migration keeps anthropology at its core for moving people with their culture and attributes to other celestial bodies into outer space.

In reality, anthropologists focused highly on the long past of humanity and its evolution rather than on its future perspective, which made them study small tribes rather than large industrial societies. The analogies in anthropology that apply to space facilitate us in realizing human consequences of leaving our natural and native habitat “Earth” to the vast cosmos into an unknown world.

Since humans set foot on other planets, we’ve been fascinated by space. We’ve looked up at the stars, dreamed of traveling to them, and imagined what life might be like outside our planet’s atmosphere. But what makes space migration such an exciting topic is that it asks questions about who we are as a species and how we define ourselves concerning the universe around us.

We all know that humans have been exploring and settling space for centuries, but what we may not know is that this activity has had a significant impact on anthropology. Exploring the humanization of space and how it has changed over time is inevitable, which leads us to the implications of space migration on the development of human societies.

With the help of technology, we are now able to explore and understand the vast reaches of our universe.

We are constantly surrounded by technology that has shaped the way we live. Our world has become increasingly reliant on technology, from smartphones to air travel. But what is the impact of technology on human beings? And how has technology shaped the way we think about space?

With the help of technology, we can now explore and understand the vast reaches of our universe. As humans, we are constantly exploring and expanding our understanding of the world around us. We have reached our beginning, deciphering the formation of our world, unleashing the facts of solar system formation, discovering the mysteries of the cosmos, and looking back in space-time. But, what the future holds for us and how we can rectify it is the question that we are looking for.

A Short History of Space Migration: Why Migrants Live in Outer Space?

The first humans who ventured into outer space were not astronauts but rather a group of migrants. Throughout history, humans have been fascinated by space and the idea of migrating to new and unexplored territories. The mystery and the promise of new opportunities have drawn people to space-time and time again, whether explorers like Marco Polo or the pioneers of space travel like Neil Armstrong. Today, we continue this human fascination with space migration by studying the motives and motivations behind migrants who live in outer space.

How Will We Survive Future Extinction Events? Scientists Work on a Plan for Surviving Mars!

The harsh realities of space have always fascinated us. Whether contemplating how life might start on another planet or envisioning what the future might hold for humanity, space has always held a special place in our hearts. And now, as we face the possibility of future extinction events, it’s more important than ever to explore space and all that it has to offer. One of the ways we’re exploring space is by undertaking space migration, which is the process of moving human beings and their belongings to another planet or Moon.

The Biggest Threat to Human Civilization- Could It Be Starvation and Famine?

Space migration is one of the most pressing issues facing humanity today, as it is feared that a massive human extinction event could befall us if we do not find a way to survive in space. With our population overgrowing and more people moving into urban areas, space has become an increasingly vital resource. However, we are far from being able to fully utilize this resource, as a lack of resources in space leaves us vulnerable to starvation and famine. For example, water is the critical ingredient for life, and without it, we would rapidly perish in a vacuum. As harsh as it may seem, space migration may be the only way for us to save ourselves from an impending human extinction event.

Anthropology, Technology and the Anthropocene: From Fossil Fuels to Solar Power

With climate change becoming an increasingly pressing global issue, it is no surprise that many people are looking to find ways to mitigate its effects. One of the most promising solutions may be space migration, where humans could be transplanted to other parts of the universe using advanced technology.

Space migration has long been considered a viable solution to address environmental problems on Earth. Recent developments in space technology make it possible for us to explore and colonize other planets. As we understand the psychological and social implications of space colonization, we will be better equipped to manage this complex process.

How Humans Will Live in Space: A Primer on Moon-Based Colonies, Asteroid Domes, and Other Futuristic Settlements

Most people know that we need to find a way to live sustainably on Earth, as the planet is finite. But few people know that we need to do the same thing for space as well. The Earth is not our only home, and we’ve already started colonizing space! Humans have been living in space for over 50 years, and there are several habitats in space that we currently call home. In this article, we will be discussing some of these habitats and what they entail for humans. We will also be looking at some of the challenges we face regarding space colonization and how we are currently addressing them. So buckle up because this is going to be an exciting ride!

Why should we think of anthropology while planning space migration?

We live in an era of unprecedented change and the humanization of space. Just a few decades ago, humans only knew about the planet Eartharth its neighboring planets. But today, we have space exploration and travel at our fingertips, thanks to the ever-growing network of satellites. This has led to a new field of study called space anthropology, which is concerned with documenting and studying the cultures of extraterrestrial societies. It is essential to think of anthropology while planning space migration. It will help us understand the motivations behind why people would choose to leave their home planet and journey into unknown territory.

Future of space migration and moving people and their culture to other celestial bodies in outer space

With the rise of commercial space travel and the increasing interest in space exploration, the future of space migration is looking very bright. As humanity begins to explore and settle other celestial bodies in outer space, people will inevitably move their culture and civilization there. This will undoubtedly bring about new challenges and opportunities and will profoundly impact human life on Eartharthth technological advances; we can expect to see a gradual humanization of space, as people can migrate and establish settlements on other worlds.

Conclusion

Space migration is an inevitable future trend that will play a significant role in humanizing and exploring space. Overcoming the sociocultural barriers to working and living in space is necessary if we want to pave the way for a better, more unified human civilization. Anthropology must continue to hold the key to promoting understanding among differentiated branches of humankind scattered through space. By doing so, we can work together towards realizing our dreams of living and thriving in space!

The Nabateans: A History Preserved in Rocks

Prologue

The ringing alarm went off, and I woke up startled yet realizing that I didn’t have time on my side; I got off the bed almost in a springy fashion and stood next to the hotel room window. Parting the heavy curtains, I could see twilight on the distant horizon. As nature painted colors on the canvas of sunrise in Amman, Jordan, I freshened up and double-checked my backpack. Water bottle, check, shades and pea cap, my camera gear, check.

I was to return to Riyadh that day after attending a conference over the preceding two days. Before embarking on the trip, I had already decided that even if I get the slightest time window, I would visit the archaeological remains of the city of Petra, which along with Al Hegra near the city of Madina in Saudi Arabia, are the footprints in the sands of time of the Nabatean Kingdom.

The Journey begins

A Medical Doctor fascinated by ancient history, the mysterious, and beyond, I took it upon myself to give Petra a visit since I had read about it and seen a lot of gorgeous photography. The previous evening, I had roamed around the hotel acquiring information as to the distance and time required for the Petra excursion ( though I had worked out the details before coming to Amman, the locals knew better). Learning enough Arabic to conversate with the locals was a plus. I made a done deal with a cab guy who was supposed to pick me up the following day before the break of dawn.

The Cab finally arrived, and after a brief chit-chat with the driver, we were on our way. It was still twilight, and I had left without having breakfast. It would take three-plus hours to reach our destination, and I had difficulty fighting off the drowsiness ( obviously without my cup of joe in the morning!). He assured me that he would make a pit stop as soon as he was on the main road outside Amman. And that he did, at a small tuck shop making coffee as well, to my delight.

A croissant to compliment the kick of the caffeine did the trick. Suddenly I was upright in the back seat. My mind was racing over what I came across at Petra, how grand it would be, and would I be able to see the whole thing and return in time for the flight back home. I also thought about which mentioned in the Holy Quran regarding the ‘Thamud’ civilization. It is purported to have been the very people of the Nabatean Kingdom.

It was explicitly mentioned about their mastery over building immense structures out of giant rocks and mountains and how they all came to a crashing halt. Snapping me out of my intellectual daze, the cabbie alerted me that our destination was near. It shows how time can be relative, passing by quickly when you are engrossed in something.

We reached the entrance of the ruins of Petra; the driver dropped me off at the entrance while giving me a pseudo-ultimatum of three hours to be out of the place since he said we wouldn’t be able to return to Amman in time. I walked to the ticketing office and got my pass as excited as ever ( after a few selfies at the gate, obviously!). I knew that the whole walk up the path to the city and back would roughly take 4 hours on a brisk foot ( 8 Km in total). I had to make it count and return in time.

The city structure of Petra and the Nabatean people

The Nabateans were Arabs who, in all likelihood, were nomads who originated from Southern Arabia and eventually settled in the area of present-day Southern Jordan, Palestine, and Northern/North-Western Arabia around the 6th century B. Some historians date the Nabatean Kingdom to have been established around mid of the 4th Century BC to 168 C.E when the Romans annexed it. Petra was the capital of the Kingdom.

As I could see, this area was in the middle of the desert, with extreme sun, aridness, and large red-colored mountains and rock formations. The Nabateans had these conditions to cope with; they were expert builders with exquisite engineering skills. They had the skills to pool and store water in underground water cisterns and aqueducts. This created a ready reserve of water in those times, and we all know how civilization and Kingdoms thrive around water bodies or even oases.

As I walked towards the security checkpoint, I ended up in a barren and dry expanse with a walking trail winding ahead. Raised rock formations eroded by the forces of nature and the passage of time on the sides of the walkway. After five or so minutes of trekking under the scorching October midday sun, huge red sandstone mountains loomed with a vertical break between the rock formations. The sheer size of these natural formations put me in awe.

The entrance through the mountains was marked ‘The Siq,’ which snaked its way through the enormous cliffs. I weighted my photography gear on my back while I kept taking photos. Cool air hugged my face and body as I walked through the twisting trail. This is expected when the shade under the rocks and temperature difference creates a cooling effect in such rock formations. On both sides of the snaking path were inscriptions, pottery, and artifacts neatly decorating the fringes.

Along these walls was evidence of depressions similar to water conduits which probably were aqueducts carrying water from outside the rock formations into the city for storage and use. Such productive use of nature’s creativity! As we talked along the continuing trail, I noticed that this was a city that was enclosed by a range of large, seemingly impenetrable mountains which served as fortification for the city.

So, the Siq, though nature’s work of art, served two purposes, first, protection and secondly, to channel water from outside the city from the surrounding city. Since the city of Petra is lower in elevation than the surroundings, this, combined with marvelous engineering, worked wonders in storing rainwater.  I met a guy from South Sudan who was also busy taking shots. We exchanged pleasantries and shared our mutual interest in Photography & Ancient History.  

As we reached the trail’s end, we could see a towering building through the wide slit.  Reaching the spot, we were mesmerized by what appeared to be a magnificent pillared structure, the pillars so smooth, with symmetry between them. The finesse which had gone into making this was nothing short of spectacular. As my homework on the place served me well, this was the ‘Treasury’  or ‘Al- Khazneh’ as they call it, of the city. 

The Nabateans were sharply skilled masons. They made immense structures out of sandstone, basically carving them out of the rock. It’s hard to believe structures like these were carved out more than a couple of millennia ago. These people had a definite structure to their society, with a Royal family ruling the city while the common folk during their assigned duties. There were practically no enslaved people.

The locals spoke a dialect of Arabic; however, one rarely finds inscriptions or records in Arabic in ruins. Most of their history, which has been transmitted, has been through the Greek and Roman historians. As we trekked along the trail, it opened up to a large plain with massive rock formations on the sides and tents, camels, and groups of people thronging the area. This was the ‘street of facades.’ Remains of tombs, and typical houses of people, were carved into the cliffs higher up on the sides.

There were tombs of the royals and the commoners. The royal tombs were built on the upper side of the cliffs while there were holes and caverns carved out below them. These are purported to be houses/tombs of the commoners. Flocks of people were gathered on the highest points of the sandstone cliffs to take photos and get a glimpse into these houses. There was a hustle of people in the central area of the plain, where there was a thriving marketplace—stalls selling souvenirs and trinkets, tuck shops selling drinks and snacks in the scorching heat.

Camels and mules with multicolored saddles; gave me a feel of what It would have been like back in the Kingdom’s hay day. There was a  small ‘Theatre’  as in a Roman theater, with a semicircular theater which could probably seat 50 odd people. This was meant for public events or perhaps entertainment. The structures I had seen till now were reminiscent of Greek & Roman architecture. From around 2000 to 2400 years ago, the Greeks were thriving in the regions bordering the Kingdom, and the Romans annexed and settled in the area later on.

Religion and civil matters

The Nabatean society had special rights of equality for women. They rose to the position of Priestesses and had property rights and to co-rule. The idols of Allat, Manawaat, and  Al-Uzza were female deities. They had attributed different responsibilities to a host of Gods.

The most enduring one is Dashura, the sun god. The inscriptions can be on coins even during the Roman tenure after they annexed the Kingdom. This is reflected in their practice of idol worship as well. They held public ( festivals ) but mostly private worship. The inscriptions and markings reflecting these deities can be seen in their tombs, on top of doorways and pottery.

 My Pal and I scurried onwards and came across a freestanding structure (the largest freestanding structure in the city ), tall and partially intact. It was called ‘Qasr-bint.’ It was the city’s main temple, and the idol deity Dushura was worshipped here. The temple is made of blocks with decorative plasterwork on both the inside and outsides of the walls. Strings of wood course between the blocks and line the walls. This was quite intricate civil engineering. 

We came across this sizeable staired structure with an endless number of steps to the top where numerous bases of pillars could be seen in a row. It was a temple. Again, it probably served ceremonial and religious purposes. The remains of the pillars remind us of how grand the structure would have been. I went up there and spent a few minutes carrying on with my newfound pal.

A few men dressed as Nabatean guards were standing near an entrance of sorts along the path. This looked like a check post which would have served the purpose of security for what lay ahead. The men wore an imitation of armor and helmets and were wielding spears. They gleefully posed for photos with us!

Nabatean Trade and Wealth

Further hurrying down the trail, we found makeshift shops and permanent ones selling some stuff in large bowls. On closer inspection, it was a wide colorful range of spices and frankincense (aromatic extracts from particular tree bark). Frankincense has been used and traded for millennia. It is burnt, and the aroma, which is earthy, sweet, and musky, is said to purify the surroundings and calm your soul. The Nabatean Kingdom’s primary revenue was generated from the trade route extended from the Yemeni coast in Southern Arabia to the dead and Mediterranean seas.

This route enabled them to do business and interact with the civilizations bordering them. Namely the Greeks, Romans, Persians, and Assyrians. They had exclusivity to this trade. The returns came in thick and fast, which enabled the Kingdom to flourish by leaps and bounds. They had an outpost called Al Hegra which in present-day is around 350 km from the Holy City of Madina. The output served as a pitstop for the trading caravans. Al Hegra also had a thriving population. The tombs and houses carved out of sandstone rock can still be seen standing amidst the barren desert.

The success of their trade and immense wealth were reasons for envy for the neighboring Greeks, with numerous attempts made to capture parts of the route; however, they were warded off by the Nabateans. Demetrius, son of the Greek King, Antigonus I, tried to raid the city in 312 B.C but failed and, in a later encounter, suffered the same fate again.

The collapse of the Nabatean Civilization and epilogue

To my respite, we ended up near the entrance of the city of Petra. I bought a few souvenirs from the market, walked towards the taxi stand, turned back, and gave it one last look. Realize how Civilizations and Kingdoms flourish with such majestic skills and wealth and how they eventually fall.  They went to war many times with the Greeks in skirmishes which they finally won, but they were no match for the invading Romans at the turn of the common era  ( C.E ).

Numerous Nabatean Kings succeeded each other. However, considered to be their greatest King was Arteus IV, reigning from 9 B.C to 40 C.E. Under him, the Nabateans regained territory from the Romans. The latter had captured it in earlier confrontations. Art, crafts, and civil rights all flourished during his reign. However, the kings succeeding him lost more territory to the Romans, and eventually, the Kingdom weakened, and wealth dwindled due to the loss of trade routes.

The Roman empire was growing in power simultaneously and eventually annexed the region as the Roman Province of Arabia Petra in 106 C.E. The cities under Roman rule went into a downward spiral. However, a devastating earthquake shook the cities in probably the later half of the 4th century C.E. This was the final nail in the coffin.  Many died along with the loss of infrastructure. The Roman Empire tried to resurrect the city’s spirit by re-igniting commerce and building churches. It said that they forcibly tried to convert many locals to Christianity.

Many probably fled the area with no sense of ownership and religious persecution. Another earthquake struck the region in the 6th century C.E. This led to widespread destruction and eventually abandonment of the cities. This is further confirmed when during the expansion of the Islamic Empire during the region of Caliph Umar, the Muslim armies found these cities deserted and forlorn. European explorers discovered the region in the 19th and 20th centuries, and the world was exposed to these magnificent ruins. The city was declared World Heritage in 1985 and one of the 7 New Wonders of the World in 2007.

I got into the cab and went on my way to the Hotel in Amman city center. What I witnessed was a testimony to how Civilizations rise to power no matter their status, prowess, or grandeur. All are swept away by the relentless flow of time. The remains of their presence are an eye-opener for us of how fragile we are.

The Cultural Diversity of Pakistan

0

The cultural and ethnic diversity across the four provinces of Pakistan makes this multi-ethnic country stand out. From Punjabis to Sindhis or from Pashtuns to Muhajirs, you will find it all within Pakistan. Pakistan is culturally, religiously, and ethnically a versatile land, and we will discover the true essence and beauty of these distinct cultures and their development through the ages below.

Cultural diversity in Pakistan
Cultural diversity in Pakistan

There is an extensive history of Pakistan’s land and how communities/ tribes from diverse backgrounds, with specific cultures and ethnicity, landed in Pakistan, creating a unified yet vicious web of cultures and traditions. Pakistan’s heritage culture reels back to the times of the Indus civilization, approximately five thousand years ago. Since then, the penetration of Islamic ideology has played a considerable role in shaping current Pakistan’s cultural dynamic. The cultural modifications in Pakistan were highly influenced by Arabic-Persian cultures and a few decades back by western cultures.

To date, numerous traditions, celebrations, food, and lifestyle has a hint of western and Indian cultures. Celebrations such as Holi (Hindu celebration), Christmas, and Thanksgiving (western celebrations) have become prevalent in Pakistan. The more we explore the culture of the west, the more we follow them.

Ethnicity

Accommodating more than fifteen major ethnic groups, Pakistan is a land of cultural and ethnic heterogeneity. The most notable communities include Punjabis, Sindhis, Pashtuns (Pathans), Balochi, Kashmiris, and Muhajirs (communities that migrated from India to Pakistan during the partition). The core communities for each ethnicity are primarily divided across provinces of Pakistan, i.e., Pashtuns are mainly concentrated in KPK (Khyber Pakhtunkhwa), Sindhis towards South, Punjabis towards East, and Balochis towards South-West. The intermixing of these several cultures, their traditions, and lifestyle are well-developed, and people are intrigued to learn about neighboring cultures within Pakistan.

Ethnicities across Pakistan

Language

Although Pakistan’s national language is Urdu, you will discover people communicating in various languages. Pashto, Urdu, Punjabi, Saraiki, and many others. Not to forget, the use of the English language in daily life has increased. If one observes, children are taught to communicate in English when they go to school. The teaching medium in educational institutes is a mix of both English and Urdu.

One remarkable ability in Pakistan’s society households is using two or more languages in homes like Urdu and Punjabi, Balochi and Seraiki, Sindhi and Urdu. It shows the cultural assortment and acceptability of different ethnic groups in our lives. With this artistic growth, the gap between fluent spoken and written Urdu languages rises. It may be a sign of us adopting other cultures at the expense of compromising the command of our national language.

Family Structure

One of the critical features of Pakistani culture can be termed “Collectiveness.” Various communities, families, and associates are highly interlinked and interdependent on one another. Social, political, and professional connections and relations are given immense regard making Pakistan a socially complex society. These loyalties within communities go across generations. The nature of this collectiveness explains the family set-ups in Pakistan. Large, extended families have lived together under one roof for decades, and to date, many family set-ups follow the same tradition.

However, with rising independence and primarily the influence of the western culture, many households have been divided so that each house caters to one particular family. People are inclined towards separate, independent homes to relieve them of financial constraints, have privacy and have a greater focus on their children and upbringing.

Food and Dining Etiquettes

Food is what brings Pakistani families and communities closer. Few traditional Pakistani foods include biryani and karahi. Pakistan is a Muslim country; hence, only halal meat is consumed. Pork or alcohol is not used in meal preparations. Food preparation and cooking style utilizes a lot of spices, rich, vibrant colors, and mouthwatering aromas. Along with desi (traditional) foods, food from other countries and cultures such as Korean, Indian, and American are also consumed regularly and are found on food menus in restaurants within Pakistan.

Pakistan is a Muslim country predominantly, hence only halal meat is consumed
Pakistan is a Muslim country. Predominantly, hence only halal meat is consumed.

Dining etiquettes have been a significant part of Pakistani culture and heritage when it comes to food. It has been the same for decades: the entire family sits together (preferably on the floor) and eats. While eating, discussions are generally based around routine life and some words of wisdom from the elders. However, the family dining experience and culture have somehow diminished in the present times. Each family member eats according to their convenience, and the spirit of a close-knit, productive dining table family discussion seems to be lost.

Clothing and Fashion

Each particular culture and ethnic group have its traditional clothing piece which portrays its identity. For instance, in Sindhis, Ajrak is a popular clothing item. However, these conventional clothing pieces are still utilized today but with a touch of modern fashion. The styling and accessorizing of clothes have been a key in cultural growth and development.

The use of jeans and t-shirts is more common than the use of shalwar kameez in daily life. Youth of the nation predominantly revolutionizes lifestyle, getting inspiration from international market and fashion trends and incorporating them into their cultural wear. However, we need to think: Is this exposure adding to the artistic growth or erasing the traces of actual ethnicity of various cultures in Pakistan?

Gender Roles

Traditionally, gender roles were very distinct. Females remained in the households and took care of domestic chores while men used to work and earn money. However, cultural growth has variegated the gender roles. Nowadays, females are working in all sectors of life, including medicine, engineering, aeronautics, and business. Higher female education is given priority across all cultures, contrary to the traditional norms that focus on male education only. Females are gaining financial independence and are encouraged by families. Early marriages have significantly reduced as the focus is shifted to education, employment, and freedom.

Multi-culturalist Pakistan is the new Pakistan. The array of cultures, traditions, and the way they have evolved along the ages is simply beautiful. Exposure to copious cultures is an essential tool for personal growth. It is what defines Pakistan.

Culture is the arts elevated to a set of beliefs.

Anthropology in Today’s Interconnected World

0

You switch on your laptop and talk to a friend on Zoom who lives in the US, email a colleague in Germany, order a new outfit from Bangalore, India, and apply online for a scholarship in the UK. This interconnection is just one way to show that you are a part of globalization.

Globalization makes people more connected socially, economically, and politically. At the same time, it assists in better interaction and behavioral understanding by letting us learn about different cultures.

The late Marshal McLuhan, a media and communication theorist, coined the term “global village” for the first time in 1964 to describe the shrinking and expanding of cultures around the globe due to fast-paced technological advances.

In that era, most people believed that cultural globalization would lead to a more sophisticated marketplace where underdeveloped countries would get support from developed countries financially and in humanitarian efforts.

Nonetheless, many people have reservations about its pros and cons. They realized that the evolution of a global village would raise conflicts among nations and could result in further fragmentation of societies and their cultures. Another concern was a division of power and domination of certain developed counties. This concern was rightly highlighted, and we witness hybrid cultures in several countries, including Pakistan.

In today’s world, the national understanding of culture has expanded due to the new world cultural framework created through the progressing interconnectedness of varied local cultures. In a broader sense, cultures are now more accurately seen as sub-cultures. And they need to understand the context of their geographical surroundings.

According to Anthropologist UIF Hanners, it is the local level where global influences are filtered, transformed, and incorporated into beliefs and practices. Hanners thinks that the local daily life is where international cultural elements get the opportunity to make themselves at home.

Hanners thinks that the local daily life is where international cultural elements get the opportunity to make themselves at home.

Impacts of Modernization

The anthropological meanings of modernization refer to the evolution process that brought about cultural, social, and economic changes with the passage of time.

In the 5th century AD, Roman adapted to Christianity and coined the term modern to differentiate themselves from Barbarians. The Barbarians were non-Christian, particularly people of the Jewish faith. During the renaissance, one had to cultivate a lifestyle based on classical Greek and Roman civilizations to be modern. At the same time, during the enlightenment period, rationalism, science-based knowledge, and the pursuit of progress were modernity’s hallmarks.

Meanwhile, several or all underdeveloped civilizations were affected by the powerful influence of developed counties, like the US, UK, Russia, and the European Union. This is why several anthropologists think of globalization as the westernization of the world.

While analyzing the detrimental impacts of westernization, socialists and anthropologists mostly blamed the US for its alleged imposition of culture and mass media. Nonetheless, several other developed countries such as China, Russia, and Europe are also to blame as they reinforce their culture globally.

Without an objective and inclusive analysis of these issues, we will be unprepared for the rollercoaster of cultural mayhem that could inevitably ensue.

Several anthropologists assert that cultural contact creates uniformity, standardization, and homogenization. The global monoculture that we observe is sterile, dull, and artificial. A prime example of this aggravation is the proliferation of American fast food restaurant chains in foreign countries. McDonald’s, Burger King, Pizza Hut, and KFC taint the cities of even former Eastern blocked countries such as Hungary. Contrary, the extended chains of Chinese, Indian and Thai foods are fanning these cultures in host countries.

By definition, culture is something that connects the deep values and structures in society, and the local or mother language plays a vital role in strengthening this bond. But we see that several languages around the globe have potentially been lost. At the same time, we observed a powerful dominance of several languages like British and American English.

A database website called “languages of the world” reveals that more than 6,912 languages, half are in danger and maybe disappear in the next several decades; they list them as “Endangered Languages.” Losing these languages poses serious cultural threats because archeologists and anthropologists are losing aspects of these smaller cultures. They are now unable to articulate their beliefs and knowledge due to the extinction of their language.

What is Acculturation?

Acculturation is a process of contact and exchange within a culture through which a group of people adopts specific values and practices of another culture that is not originally their own. The adaptation could be minor or, to a greater extent, results in a cultural shift.

When the transitioning process is extreme, assimilation occurs wherein the original culture is entirely abandoned and, as a result, a new culture emerges. However, other outcomes can vary from minor change to total change, including separation, integration, marginalization, and transmutation.

Meredith Small, a cultural anthropologist and author of the book “Our Babies, Ourselves: How Biology and Culture Shape the Way We Parent, describes a test case she studied. This is about Lebanese and Australian mothers whose cultures led them to parent in very different ways. As a result, they feel resentful toward the mothers of the other culture.

Since children play a significant role in all world cultures, it makes sense that each culture would have very different expectations and customs surrounding parenting. This tiny slice of cultural practice is representative of many other ingrained cultural differences around the globe. Perhaps if existing cultures were not already set up to contradict each other, a peaceful threshold could be reached.

With these changes comes responsibility, as humans, to consider the implications of our shifting realities. Without an objective and inclusive analysis of these issues, we will be unprepared for the rollercoaster of cultural mayhem that could inevitably ensue.

It is idealistic to assume a situation where cultures can merge without losing their essence while staying peaceful about how global culture gets in a new shape. Each country feels secure only when it protects its cultural beliefs. Nonetheless, the world has to shift to noncontroversial models with the growing pace of modernization.

THE FIRST PHOTO OF OUR MILKY WAY’S BLACK HOLE REVEALS

0

Our galactic home, the milky way, hosts a Sagittarius A* Black Hole but we had not seen its image. That was until now after we got the First Direct Visual Evidence of its existence. The photo was taken by the observations of the Event Horizon Telescope Collaboration (EHT), an Earth-sized array of Eight – Observatories. Together, capturing the data of its constant and bulleting movements throughout a prolonged time.

The Sagittarius A* had previously made headlines after its discovery was cited as a “Supermassive compact object at the center of our galaxy” and bagged the 2020 Nobel Prize in Physics by Reinhard Genzel and Andrea Ghez. Earlier this week, Dr. Feryal Ozel, a professor at the University of Arizona and a member of the Event Horizon Telescope Science Council held a press conference and presented this groundbreaking discovery, an additional contribution to research by EHT Collaboration after previously developing the picture of M87 Galaxy’s Black Hole.

Known to be around 4 million times the mass of our Sun. As you can see a center-principal dark region, where the Black Hole is, is orbited by the light coming from magnificently heated gas around it under the cause of gravitational acceleration. For a similitude of understanding scale, the ring has the size of Mercury’s orbit around our Sun.

Breaking into the science of this image, we know that the image was taken in submillimeter radio waves, revealing the presence of the Black Hole in the heart of the galaxy, eating the nearby hydrogen gas, the clarity of the image to this extent took several years, from the data collected in 2017. As the Sagittarius A is continuously evolving, when compared to the data of the previously released M87 Black Hole, because the M87 was so massive that it takes hours to complete a full orbit due to the matter whirling around it, this means that we can observe M87 for a longer time, while having a shorter time to observe the Sagittarius A*, as it’s approximately 1,000 times less small than the M87 Blackhole, eventually having 1000 times faster change – Analogically speaking. The black hole lives about 27,000 light-years away from Earth.

Dr. Katie Bouman, a Computer Scientist & Astronomer at the California Institute of Technology, who also co-led the EHT’s Imaging Working Group explained that the orbit of matter around the BlackHole is so quick that it’s changing every minute. Comparing it with taking a time-lapse photo of a speeding bullet, is not easy to do, which took several years to bring the end product – The Image of the Sagittarius A* Black Hole.

The challenge is divided into three major stages, which are as follows:

  • Design
  • Development
  • Demonstration

Accomplishments

Team Foxtrot has competed in the IMechE UAS Challenge in the United Kingdom (UK). In the debut year of the challenge, they won the “Highest Place New Entrant Award of 2019” and stood among the Top 10 participating teams from across the globe. In 2021, Team Foxtrot bagged the Business Proposition Award while also finishing in an esteemed 5th place in the virtual competition.

The team also scored a perfect 15/15 score on its First Design Review: a feat that is worthy of appraisal. In this year’s challenge, the Team scored another perfect score of 20/20 on its Preliminary Design Review. The team was warmly welcomed by national media for their extraordinary achievements and invited for interviews by Expresso, Neo News, and PTV World

Team Foxtrot also organizes STEM outreach programs in schools to enlighten them about the endless possibilities and opportunities in engineering and empower girls interested in the field. It focuses on enabling young minds to acquire UAV-related cognitive skills and teaching pupils about the practical applications of autonomous UAVs in the present period, including their use in humanitarian aid missions.

 Generous sponsors have enabled them to receive these accolades in a short period. Their previous sponsors/partners include HBL, E-Wall, and FFC, whereas Smart Hobby and Woot Tech are our current ones.

This Year’s Challenger

This year’s project, Barq, is designed to complete all core tasks of the challenge besides the optional tasks of Endurance and Area Search. Project Barq is a CTOL (Conventional Take-Off and Landing) design having a tri-motor configuration to enable short take-off and precision landing within a limited 10 x 10 m area. The aircraft uses a V-tail and glider wings to combat air resistance and is fabricated of carbon fiber and polystyrene to maximize the strength to weight ratio. This also gives it high maneuverability and an enhanced endurance capability. In addition, it has retractable landing gears and a maximum take-off mass of 9.3 kg with a payload-carrying capacity of up to 3.5 kg.

It can fly to speeds of up to 60 knots and has a reverse-thrust mechanism. With appreciative feedback from the IMechE and all members working hard in their respective domains, Project Barq is all set to fly high and make us proud in the 2022 UAS Challenge.

WHL0137-LS: THE EARENDAL, THE FARTHEST STAR WE KNOW TODAY

0

Being 13.8 billion years old, the universe is the current estimation of the creation itself. We have recently sent NASA’s James Webb Space Telescope at the position L2 to look back into the time, looking into the Infrared-NIR radiation. So, we can look for one of the first stars and galaxies in the universe. Interestingly, a staggering discovery was made by the Hubble Space Telescope as “Earendal,” the farthest known star yet – relating from the beginning of time, astronomers are calling it. In old English, it’s known as the “Dawn Star.”

Earendal was discovered through the Gravitational Lensing technique through the Hubble Space Telescope, to a comoving distance of 12.9 Billion Light-Years away from the HST. The distant star could be from the first 900 million light-years from the big bang. This discovery broke the previous farthest known star MACS J1149 Lensed Star 1, a supergiant blue, with a distance of 9.34 light-years in time, a distant second to only WHL0137-LS discovered earlier this year. The research came to the public by the astronomers in a paper in nature, “A Highly Magnified Star at Redshift 6.2”, suggesting the last confirmations of the star by James Webb Space Telescope’s observations for spectral classification and retaken distances. 

This image highlights the star, Earendal’s location along a ripple of space-time that helps the star to be magnified and found over such a huge distance - nearly 12.9 billion light years. Credit: Credits: NASA, ESA, Brian Welch (JHU), Dan Coe (STScI)

The studies mentioned above suggest that the mass of these types of stars is somewhere approximately 50 times of our sun. The image shown from the Hubble data made the discoverer notice the fragile, long red arc, which seemed to be a galaxy warped and amplified light by the cluster. Atop that bright red arc, there’s “Earendel,” a spot that is too small to be considered a galaxy; after rigorous research and methods, “We stumbled into finding that this was a lensed star.” quoting Brian Welch, the lead author of the paper and discoverer of the farthest star.

Contribution of Marine Microalgae to Sustainability

0

Oceans and seas host the majority of biomass and global energy cycles as they make up more than half of the Earth’s surface (Mestdagh et al., 2020). Significant changes occur within marine ecosystems due to the difference in the environment caused by warming oceans (Yun, 2022). The seriousness of the matter can be estimated from the fact that in 2018, the concentration of CO2 in Hawaii was recorded to be 409.23 ppm, which is the highest concentration estimated in about the last 3 million years (Gregory, 2021).

One of the main reasons behind the increase in temperature is emission of CO2 in the atmosphere due to exessive use of fossil fuels, resulted in several social, economic, and environmental challenges, which are also severe issues facing today.

There is a need for innovative and sustainable ways of sustainable renewable energy to tackle climate change. The marine ecosystem provides a wide variety of solutions for environmental issues. Microalgae present in different aquatic environments have proved themselves capable of absorbing CO2 from the atmosphere and ultimately reducing its amount from the environment (Peter et al., 2022). This article explores how marine macroalgae can help achieve many of these objectives, including improving aquaculture, reducing CO2 emissions, and resulting in a healthy environment.

“We may have stumbled onto the next green revolution.” ~ Charles H.

WHAT ARE MICRO-ALGAE

Tiny living organisms within the marine environment are called marine microbes, and they are only visible under a microscope. 98% of the total biomass comprises these microorganisms, and they supply the majority of the oxygen to the world. They are also the world’s greenhouse gas processors (AIMS, 2022).

Algae are photosynthetic organisms capable of growing in a wide variety of aquatic habitats like oceans, rivers, ponds, lakes, etc. Algae can also tolerate different conditions, including pH values, salinities, and temperature at a wide range. They can grow alone and in symbiosis with other organisms (Barsanti et al., 2008). According to size, we can classify Algae as microalgae and macroalgae. Macroalgae are large-sized, multicellular organisms that can be seen through the naked eye. On the other hand, microalgae are small-sized, unicellular organisms that can be seen with the help of a microscope (Das, Aziz, and Obbard, 2011).

BENEFITS PROVIDED BY MICRO-ALGAE

Microalgae offer a wide range of applications in cosmetics, medicines, health supplements, and biofuels, among other things (Das, Aziz, and Obbard, 2011). Microalgae have also been shown to be helpful for the treatment of wastewater and the reduction of CO2 emissions from the atmosphere due to these advantages (Brennan and Owende, 2010). Algae photosynthetic carbon sequestration has been identified as having enormous promise in efforts to achieve global or regional carbon neutrality.

As important drivers of crucial biogeochemical cycles in oceans and freshwaters, algae play an important role in CO2 absorption from the atmosphere and the mitigation of global climate change. These activities have a significant relationship with the United Nations SDGs. Using marine macroalgae as a feedstock for biofuels to reduce reliance on fossil fuel combustion as a source of energy, we are investigating how marine macroalgae can assist in achieving some of these goals.

This includes improving aquaculture, contributing to the “Blue Carbon” CO2 drawdown to mitigate climate change, and supplying biomass as feedstock for biofuels. While further research is needed, we believe that growing macroalgae in the air has tremendous potential in terms of cutting CO2 emissions and improving aquaculture production conditions. In addition to promoting biosynthesis and biomass development, the photosynthetic activity of macroalgae can modify pH levels as a consequence of CO2 depletion/HCO3– accumulation.

There is a possibility that this will mitigate the adverse effects of ocean acidification by buffering the pH fall caused by increases in human carbon dioxide emissions. However, despite its growing importance, macroalgal aquaculture now accounts for just a tiny amount of the Cdrawdown generated by wild macroalgae populations and an even smaller portion of world CO2 emissions.

A more substantial contribution to the reduction of human CO2 emissions and ocean acidification may, on the other hand, be made by expanding intensive macroalgal aquaculture in a more significant way. (Gao and Beardall, 2022). Jill Kauffman Johnson, leader and advocate of algae, in a TED talk titled “Beer to Algae; the future of low carbon food systems,” stated that “microalgae, fermentation can be an opportunity for producing food that is more nutritious by utilizing fewer resources while eliminating greenhouse gases. It will protect biodiversity and ecosystem and can be one of the most powerful solutions for addressing climate change.”

MICROALGAE CARBON METABOLISMS

As the principal oxygen-producing photosynthetic microorganisms on the planet, microalgae, commonly called autophototrophs, contribute to over half of the worldwide CO2 fixation. However, it is possible for certain microalgae species to flourish in dark conditions because they have heterotrophic metabolism. Some algae strains can thrive mixotrophically under particular conditions.

Heterotrophic or mixotrophic growth of microalgae is crucial as it enables microalgae to store the organic carbon found in wastewaters, which would otherwise be released in the atmosphere if broken down by bacteria (Zhou et al.,.2017). The types of carbon that microalgae can assimilate, the processes involved in microalgae CO2 capture, and high concentration CO2 stress will all be explored in the following sections.

Heterotrophic or mixotrophic growth of microalgae is crucial as  it enables microalgae to store the organic carbon found in wastewaters.

INTEGRATION OF INORGANIC CARBONS BY AUTO-PHOTOSYNTHESIS 

  • CARBONS INORGANIC IN THEIR MANY FORMS

A variety of dissolved inorganic carbon (DIC) species, including CO2, H2CO3, HCO3, and CO32, may be taken up by microalgae in the aquatic environment. On the other hand, terrestrial plants have a substantially limited spectrum of DIC assimilation than aquatic plants. The DIC forms are very variable and rely on various factors, including pH, mixing velocity, and microalgae concentration. The DIC forms preferred by different strains of microalgae may be diverse from one another (Hernández-López et al.,2021).

  • CO2 ASSIMILATION THROUGH AUTOPHOTOTROPHISM

Microalgal CO2 fixation is converting CO2 and water into organic compounds by using the photosynthetic intermediates ATP and NADPH, which are produced by algae. In the same way, as terrestrial plants do, microalgae acquire CO2 via the Calvin cycle, which consists of three stages: carboxylation, reduction, and regeneration (Zhou et al.,.2017). Overall, the carboxylation stage comprises the incorporation of CO2 into ribulose-1, 5-bisphosphate (RuBP) by ribulose-1, 5-bisphosphate carboxylase (RuBisCo), which results in the synthesis of two molecules of 3-phosphoglycerate (3-PGA) as a result of the reaction (Maity, and Mallick,2022).

Then, with the help of 3-phosphoglycerate kinase and glyceraldehyde phosphate dehydrogenase, 3-PGA is phosphorylated and reduced to generate glyceraldehyde 3-phosphate, which is then phosphorylated and decreased again to form 3-PGA (G-3-P). At the end of the process, RuBP is restored by a sequence of reactions, and the cell is ready to begin the next fixation cycle. In microalgae, CO2 is delivered to RuBisCo by a series of the cell membrane, chloroplast membranes, cell wall, cytoplasm, stroma, and extracellular boundary layer crossings that occur sequentially (Merlo et al.,.2022).

FUTURE IMPLICATIONS

Marine algae and their derivatives are becoming recognized for their potential use in environmental remediation efforts. They offer a variety of biotechnological exploitation as well as usage in industry. Their utilization is beneficial to several biological factors that are thoroughly documented in the scientific literature. They have a significant potential for lowering levels of environmental contaminants.

Microalgae biotechnology is becoming more popular, and it may use to produce a variety of environmentally beneficial products, including biofuels such as biogas, biodiesel, and even bioethanol. The byproducts generated may also be utilized in other industrial operations due to their versatility. Microalgae have the potential to reduce related environmental problems by recycling carbon dioxide from the atmosphere.

Marine microalgae are beneficial in creating biological resources, but they also serve as a generator for the marine environment. They contribute to the movement of energy throughout the ecosystem and also impact the overall productivity of the ecosystem, whether directly or indirectly. They are intimately associated with fishing resources, aquaculture, and geological protection, among other things (Wu et al., 2021).

CONCLUSION

Extreme weather events induced by climate change are wreaking havoc on people’s livelihoods, while the loss of marine, aquatic, and terrestrial biodiversity exacerbates the problem. The high rate of CO2 in the atmosphere is the primary reason behind global warming today. The best way to reduce CO2 from the atmosphere is by controlling its emission into the atmosphere. But as the world’s population is growing at a very high rate, it is increasing societal demands.

These increased demands are causing a development in industrialization, resulting in raising the rate of CO2 being emitted by different sectors, especially the transportation and energy sectors, into the atmosphere. Therefore, the governments should collaborate with industry partners and scientists to take any action to either limit or tackle these issues. Micro-algae have been proved very beneficial for converting CO2 into valuable biomolecules. As the utilization of microalgae is profitable, sustainable, and feasible at a global level.

With BIR-D, drone shows light up Pakistan’s skies

0

On 20th September 2020, 3,051 Unmanned Aerial Vehicles (UAVs), in China, took part in a dazzling drone show to break the record for most UAVs airborne simultaneously. A patchwork of drones, cleverly combined with lights and intricately patterned, presented the Chinese Space Station. This synchronized flight of a flock of drones flickered lights and changed positions to show different themes and objects. Drone shows are gaining popularity around the world. With many shows being used to litter the night sky with light and glamour at big events or occasions.

However, synchronizing such a massive hoard of drones to take an integrated pre-programmed flight with flawless precision is easier said than done. It’s like an orchestra, for the performers to act as a collective, each performer must do his/her bit at the right time. The collective effort then makes a melodious composition. But to orchestrate such an impeccable collective effort, the orchestra needs a conductor. The conductor is like the puppet master, who decides what and when each performer plays. The conductor acts as the nucleus of the entire collection which drives the flow. Similarly, the swarm of drones needs its conductor too, a nucleus that can pre-program each movement of the drones to generate a fascinating synchronized drone show.

Drone shows are gaining popularity around the world. With many shows being used to litter the night sky with light and glamour at big events or occasions.
Drone shows are gaining popularity around the world, with many shows being used to litter the night sky with light and glamour at big events or occasions.

Enter, Wajih Ajmal Siddiqui, the conductor that drives his swarm of drones to make elegant patterns in the night sky. He’s the boundless ambition and the relentless drive behind his startup, aptly named, Bir-d (Add Instagram link here). Wajih is a mechanical engineer by education, acquiring his degree from City University in London. After that he returned to Pakistan and boarded a ship a sailed for faraway lands. While surrounded by sea, under the bright moonlight, Wajih’s mind would be occupied with fascinating ideas. Innovations that might change the world. Until he settled on Bir-d. While watching a drone show in China, enchanted by the technological fireflies in the air, he had an idea. An idea that led to the creation of Bir-d.

Wajih is a mechanical engineer by education, acquiring his degree from City University in London.

A twist of purpose, unrelenting drive, and unending ambition led Wajih to believe that such drone shows can be effectively used for corporate mass marketing campaigns. So, he rolled up his sleeves and got to work. Spending sleepless nights on his roof, he started work on synchronizing flight paths of multiple drones. The work was daunting but Wajih was tenacious in his effort. He quit his job to make more time for his grand idea, despite everyone warning him not to. Then to acquire the platform for the essential synchronization and integration of the flight paths of these drones, he scraped up whatever little savings he had and made the purchase. Wajih had gone all-in on his idea. The path was not easy and in the face of repeated failures and obstacles, his thrust continued. After endless rounds of testing with an increasing number of drones, finally, he achieved the accuracy he was aiming for with 50 drones shining bright in the night sky.

Using the flock of drones in its inventory, Bir-d shepherds them into different corporate logos and taglines for mass marketing.

Using the flock of drones in its inventory, Bir-d shepherds them into different corporate logos and taglines for mass marketing. The logos or taglines, whatever pattern the conductor may prefer, then hovers in the vast expanse of sky, shifting colors and themes accordingly. This is an innovative approach to marketing that doesn’t occupy rented space and has incredibly high visibility (who wouldn’t look at shining lights in the night sky?!). It also has the ‘x factor’ which entices you towards the company that advertises itself in such a glamourous way. Bir-d has taken marketing to another level, lifting your company to the skies, shining and capturing thousands of eyes and hearts.

Tidal Power: A Sustainable Source of Energy

0

Tidal power is a form of hydropower, a renewable source of energy that uses the rise and fall of waves produced by the surge of ocean waters (Society, 2011). The rise of the tides is the product of the gravitational interplay between the sun, moon, and the earth. 

Moreover, the increase in the inclusion of tidal energy for the generation of power owes to its sustainability, resulting from the oceanic tides’ high predictability compared to other renewable sources, the wind and solar energy (“Tidal Energy | PNNL,” n.d.). 

Tidal power is an innovation of the old school practice

Dating as far as the Middle Ages and even having historical evidence in Roman times, tidal energy was used to drive grain mills. However, the first time that tidal energy was proposed to be used as a source of generating electricity dates to Victorian times. 

That led to the establishment of the first-ever tidal plant, the La Rance Tidal Barrage in France, which was operational since 1966 (Neill et al., 2018). This is the starting point for the massive construction of dams barrages in the other European States to utilize tidal energy for electricity generation. 

However, by the late 90s, these constructions faced several setbacks due to the number of potential spaces being occupied by already built dams. The up roaring costs and several other factors associated with the social and economic challenges seemed unaffordable (Moran, Lopez, Moore, Müller & Hyndman, 2018). 

That led to the establishment of the first-ever tidal plant, the La Rance Tidal Barrage in France, which was operational since 1966.
That led to the establishment of the first-ever tidal plant, the La Rance Tidal Barrage in France, which was operational since 1966.

Tidal Barrages and Tidal Fences and their negative contributions to the environment

Tidal barrages utilize the tidal surges, the rise and fall of the tides, to drive the turbines and, thus, generate electricity (Hanania, Heffernan, Jenden, Stenhouse & Donev, 2021). Contrary, a tidal fence is a form of technology characterized by a steel or concrete structure that resembles a fence and utilizes the fast-flowing tidal surge of the oceanic water to generate electricity. 

The fence is famously introduced as a cross between a tidal barrage and a tidal turbine stream system (Tidal Fence and Underwater Tidal Fence Turbines, n.d.). That said, before the already mentioned stance of tidal systems having negative aspects, the tidal barrages, the unique system that was structured very similar to dams for tidal energy management, have several harmful environmental contributions. 

Most importantly, the tidal basins and the surrounding where they establish create potential risks to aquatic plants and animals by altering the salinity of the oceanic water. Moreover, the tidal barrages are prone to impact the tidal levels by increasing the turbidity and affecting navigation (Moran, Lopez, Moore, Müller & Hyndman, 2018). 

Current Prospects 

There is undoubtedly an expanding need to opt for renewable energy resources with the ever-growing energy crisis worldwide. With the great predictably level of tidal surge and their dependence on the earth’s gravitational pull, they prove to be the most reliable sources present. However, there need to be some amends in how the system was previously operated. 

Most importantly, the situation calls for the application of innovative solutions suggested as: 

  • Nullify the salinity alteration of the tidal systems.
  • Not harming marine life’s health.
  • Have a negligible effect on the tidal level.

The impacts of tidal energy systems on the environment and society need to be fixed for reviving tidal power in the present-day world.
