ALBERT EINSTEIN: The narrator of untold tales of the Universe

Walter Isaacson, the author of “His Life and Universe”, reveal a juicy bit of information from the early life of never forgotten physicist, the one and only “Einstein”.


In 1895, the sixteen-year-old bright student stood second in his class (according to the records of exclusive college preparatory school in Aargau Switzerland, which survived in those days).
Isaacson wrote it in his book in these words, “Alas, the name of the boy who bested Einstein is lost to history.”
So it might be a surprising fact for some that, the man who is a synonym of genius and who told us about the untold tales of the universe, put out the theories which were unimaginable at that time, was at one point not the most intelligent student in his class.

It makes one think why and how a child from a middle-class family became interested in physics? What were the forces which compelled him to pursue these uncharted territories of physics and laws governing the whole of the universe?

Young Einstein

Childhood and Education


Albert Einstein, one of the greatest minds of the 20th century, was born on March 14, 1879, in Ulm, Württemberg, Germany. Albert’s father, Hermann Einstein, was primarily a featherbed salesman and later ran a small electrochemical factory. His mother, Pauline Koch, was a housewife. Both of his parents were from a long line of Jewish heritage and their ancestors had been living in Southern Germany for many centuries. His mother came from a fairly wealthy family and was known for her wits. She also liked music and that’s probably the reason Albert got developed an interest in music from a young age. Albert had only one younger sister Maria (who went by the name Maja). Like most siblings, they had their differences but Maja would grow up to become one of the best and closest friends of Albert.

Learning Difficulties

From early childhood, Einstein faced problems in learning. He was especially slow in learning how to speak. He used to whisper to himself before saying the words out loud. Due to this tendency of repetition and whispering, his maid nicknamed him “der depperte” — the dopey one
Even at the age of nine, he was unable to speak fluently. Many of his teachers thought Albert was mentally weak. As a child, Albert preferred to play by himself rather than with other boys his age.

Fascination with Music

Einstein had a variety of hobbies as well. He enjoyed constructing towers with playing cards and building complex structures with blocks. He also liked to work on puzzles or read books about mathematics. It was Albert’s mother who introduced him to one of his favorite pastimes; music.
At first, Albert wasn’t sure he wanted to learn to play the violin. It seemed too regimented. But then Albert heard Mozart and his world changed. Einstein once said that “Mozart’s music is so pure and beautiful that I see it as a reflection of the inner beauty of the universe itself”. Later in life, Albert would turn to music when stuck on a particularly difficult scientific concept.

Sometimes, he would be playing his violin in the middle of the night and then suddenly stop as a solution to a problem jumped into his mind. As an older man, Einstein explained how important music was to his life and his work saying, “If I were not a physicist, I would probably be a musician. I often think in music. I live my day-dreams in music. I see my life in terms of
music Influences.
When Albert was around the age of five or six, he fell ill. To try and make him feel better, his father bought him a compass to play with. Einstein became fascinated with the compass. How did it work? What was the mysterious force that caused the compass to point north? Einstein claimed as an adult that he could remember how he felt examining the compass. He said it made a profound and lasting impression on him even as a child and sparked his curiosity to want to explain the unknown. The second wonder in young Albert’s life was his discovery of a geometry book at the age of 12. He called it his “little sacred geometry book”.

Yet another important influence on Einstein was a young medical student, Max Talmud. Talmud became an informal tutor, introducing Einstein higher mathematics and philosophy. A pivotal turning point occurred when Einstein was introduced to a children’s science series “Popular Books on Physical Science”, in which the author imagined riding along electricity inside a telegraph wire.

This imaginative question dominated Einstein for the next 10 years: what would a light beam look like if you could run alongside it? If light were a wave, then light beam should appear stationary, like a frozen wave. Even as a child, though, he knew that stationary light waves had never been seen, so there was a paradox.
After three years attending the local Catholic school, eight-year-old Albert changed schools to the Liutpold Gymnasium where he would spend the next seven years. Einstein felt that the teaching style at Liutpold was too regimented and constraining. He did not enjoy the military discipline of the teachers and often rebelled against their authority. He compared his teachers to drill sergeants. While there are many stories telling about how Einstein struggled in school and even failed in math, these are not true. He may have not been the ideal student, but he scored high in most subjects, especially math and physics. As an adult, Einstein was asked about his failure in math and he replied; I never failed in mathematics. Before I was fifteen I had mastered differential and integral calculus.

Adolescence:

Originally, Einstein was destined to take over his family business, but when it failed in 1894, Einstein’s family moved to Italy. There he wrote his first scientific paper, in his teen years, which investigated the nature of either – a hypothetical consequence of how light travels through space that Einstein later disproved. After that, he continued his education at various univer-sities in Europe and one after the others, published and researched on ground-breaking work.

On 14th September 2015, Laser Interferometer Gravitational-Wave Observatory (LIGO) detected the distortions in space-time caused by passing gravitational waves generated by the collision of two black holes nearly 1.3 billion light-years away. The cataclysmic event is extremely violent but by the time the disruptions in space-time reach earth, due to such an
infinitesimally vast distance, its intensity is vastly reduced. In fact, by the time gravitational waves from LIGO first detection reached earth, the amount of space-time wobbling they generated was thousands of times smaller than the nucleus of an atom! Interestingly such kind of phenom-enon producing gravitational waves had been predicted by Albert Einstein’s theory of General Relativity 99 years ago.  Although born to middle-class Jewish parents he challenged the Newtonian laws of physics which had been prevalent for more than two hundred years and changed the human viewpoint of the universe through his famous “Theory of General Relativity”.

Before his death, Einstein published a total of more than 300 scientific papers. From being a dull student who could not even speak properly, Albert Einstein became one of the most famous scientists of the 20th century. His genius and intellect were accepted worldwide and the theo-retical predictions he made long ago have been proven correct- the latest one in 2015.

The message to take here is that, yes, it is mandatory to have good grades in school, but it does not define what your gifted skills are. There is no fundamental law which defines that every genius should always top the class. Genius is one who comes up with new ideas, sometimes weird as well.
The quote I love most of this great scientist is “imagination is more important than knowledge” hence it is your imagination which makes you mastermind.
So next time, whenever you look at the moon, at the stars, the world around you, the cars, the animals, try to imagine, whatever you can, the stupidity levels does not matter. As Einstein says, “the difference between stupid and genius is that genius has its limits”.

A Paradigm shift in Science Journalism

0

Likewise, other countries of the world, in Pakistan the academia has fixed a borderline between the humanities and the general sciences and this division probably more absolute more than past because it seems almost practically impossible for a student to engage him/herself in two simultaneously different subjects. But still, a lot of people are interested in both and willing to read, write, or to know about what is happening in the various fields of science. This is not because the storytelling defines us as a human but it’s natural to be attracted by a scientific explanation of what we humans are, where did we come from and what is our place in this vast universe?

Science writing can play an important role in engaging a layman with science & technology and modern advancement. Consequently, it brings the work of researchers and scientists from the observatories/lab to the public spotlight. A science writer does not always need detailed, in-depth exper-tise, but should have a vast and up to date knowledge of a particular field of science and concerned topics. But the effort to become a science writer does not end here, a true passion and the ability to narrate pure scientific concepts to a non-scientific reader are mandatory as well.


The newly emerging field of science writing has caught the attention of an overwhelming number of people have good skills in writing. In the western culture, the students usually kickoff their career as a freelancer during their schooling, but here in Pakistan, neither it is promoted by our acade-mic intuitions nor by print or electronic media.

At its best, science writing is an emerging field of journalism that needs more than a desire to become a science writer. It is a matter of fact that a fewer number of writers broken into the profession through science blogging in Pakistan. Since it’s not so easy to make a career, it almost always takes month or years of unpaid labor. For most of the beginners, science blogging is not a standalone strategy but a tool for spreading awareness and passion for science among the masses.

I have been in print and electronic media for two years and with hundreds of my write-ups including but not limited to astronomy, astrobiology, and space-based astronomy, I tried hard to promote the passion of science writing in our new generation. When I started my writing career from ARY NEWS, there were fewer members of the science community who believe that science can be a genre in mainstream media. Eventually, the interesting write-ups by a few other passionate science writers helped more writers to come forward, define their beats and further hone their skills into this vibrant new digital age.

Consequently, the great motivation I got from the success stories of Pakis-tani scientists working abroad in NASA, ESA, and world’s top universities like Harvard and Oxford universities, whom I interviewed at times and had a meaning conversation on the lack of scientific research and writing in Pakistan, I came across a conclusion that the “bad science” our academia has been providing to our new generation is the backbone behind this lagging.

There are a fewer number of individuals have been struggling hard to make science as a genre and to reshape the narrative of science journalism in Pakistan. The monthly Urdu science magazine “Global science” had been promoting science for more than a decade and now a few of other public-ations are waving in print and electronic media as well. Arguably, the best
science and technology magazine in the country at the current moment is technology times, whereas MIT technology review and Spectra magazine by UET Lahore students are making their way out to in journalism.

Eventually, with the support of the journalist community, a handful of science enthusiast and writers has recently been launched an online English astrophysics magazine “Scientia” which is the first of its kind in Pakistan. No doubt this is the much-needed initiative that provides the
equal number of opportunities to skilled science writers who decide to strike out as a freelancer and having a passion for the promoting astro-physics, astronomy, astrobiology, Space & Earth Sciences. This is a unique opportunity for local talent either writers, science communicators, resea-rchers, or astrophotographers to show their talent on a genuine platform worldwide and also to tell science stories to a lay reader in Pakistan. The magazine contents like special science outreach reports, astrophotography, kids’ corner, and random astronomy articles give a chance to local talent to grow and evolve.

The new Government got overwhelming attention of common people in Pakistan with their slogan “NAYA PAKISTAN”, as per pre and post-election announcements the government beckons towards framing a new people-centered development paradigm to provide basic needs like quality educ-ation, health, and employment facilities on an equal basis. However, these efforts will bore no fruit unless we come across a scientific framework of all problems either social, economic, environmental or else. We are hopeful that the government and public sector will strengthen their hands in this much-needed initiative that eventually result in a better understanding of everyday problems for a layman and to reshape the narrative of science
journalism in Pakistan.

300,000 more galaxies added to the map of the Universe

We know that the components of the universe are infinite. New research on the night sky revealed hundreds of thousands of new galaxies that were previously hidden. The study was done in an observatory in Paris where such telescopes were used that detected the sources of light not visible through other simple tools and instruments.
It was not an individual effort, rather a team of international expert astronomers from 18 countries worked together on this project. It was explained that the discovery was groundbreaking, in that it unveiled some of the hidden mysteries and enigmas of the universe including the phenomenon like the evolution of galaxies and black holes etc.

The radio astronomy technique was used to observe the sky above the northern hemisphere and distant galaxies that were 300,000 in number were revealed. At first, these were labeled as unseen light sources and the images perplexed the scientists who studied in detail to reveal the true nature of the things they had seen. Cyril Tasse, a researcher at the Paris Observatory, said that “This is a new window on the universe”.
The mentioned technique helps to identify radiation and the changes produced when heavenly bodies interact. LOFAR (Low-Frequency Array) telescope was used to detect the trails of radiation, that extends to over millions of light years, and energies produced after the merging of galaxies.
The sources can then be further pinpointed after analyzing the obtained data.
These new light sources (or galaxies) can also help in figuring out the mysteries of black holes. The black holes are unique as they can engulf every matter due to a strong gravitational pull and they emit radiations afterward. The development and formation of black holes can be unders-tood by studying and analyzing this new research in depth as well. One may be surprised to learn that the map created by these observations has the same amount of data as ten million DVDs, but it only covers two percent of the sky!

SUPERMOON AROUND THE WORLD IN PICTURES

The phenomenon of supermoon occurs when the full moon is at the closest distance to the Earth in its orbit. Such a moon is unusually brighter and closer than at regular days. This term has been used for quite a long time but gained popularity in recent years, when three supermoons occurred in a row. It happens quite a while and in the year 2019, two supermoons have already occurred on Jan 20-21 and Feb 19, with another one to appear on March 21.

A Ray of HOPE in the DARKNESS

There is a troll in ancient myths that an ugly creature, either a Giant or Dwarf lives in dark places such as caves or caverns.  This creature always waits for anything passed by as a quick meal. A New York-based technology website ‘lifewire’ made an internet troll as a new version of the same mythical character. They are angry and disruptive like the original character more often, without no reason and can cause troubles on the internet.
In Pakistan’ case, we can found thousands of such trolls on social and mainstream media having a large number of followers who in general, are sharing their personal views and ideologies, either religious or political and our electronic media is deliberately promoting these trolls. It is a matter of fact that here in Pakistan,  almost all the media houses except PTV have been ruling by the corporate sector, who are prone to run media outlets with a typical business approach. Although, the literacy rate in last two decades has increased up to a significant level, especially in urban parts of all provinces of Pakistan the intellectual and liberal audiences have never been in their priorities and owners always apply cost-cutting measures to ensure more profit and high TRP ratings.

Eventually, the majority of the audience, either readers or viewers are forced to watch what is being aired or published by media houses as ‘news update’ or under the banner of ‘entertainment’, regardless of fact that most of the news are not authentic. However, updating their viewers about each and every advancement happening in the universe should be the prime responsibility of News organizations, instead, they have successfully created an illusion in minds of viewers to consider political advancements as ‘News’ only.

In such a scenario, it is quite sensational that the journalists in mainstream media are being used as puppets who are forced to blindly follow the policies of media houses and it is difficult if someone wants to pursue a career in the least interested beats like ‘science journalism’.

Science journalism deems as a daunting and least worthwhile beat in our News industry and why it shouldn’t be, because science based on facts and findings as well as on authenticity. But the ‘DON(s) of our media is brought up with business mindsets and are only interested in BENEFICIAL NEWS, which is a piety trade of Media outlets.

In the current face of communication technologies, the national borders are becoming increasingly meaningless and the social media giants such as Google, Facebook and YouTube have outnumbered the population of world’s most populated countries like China or India. Therefore, like the rest of the world, the Pakistani media is also in the phase of transformation from electronic to digital. Now our Business guru’s are having real-time data of news categories, and they exactly know about the interest of masses through these social giants.

Sadly but it is a sharp truth that science has never been in our people’s priority, and they are more interested in entertainment, politics and weird sort of News stories. This makes it easier for news editors to categorize Science as second-grade news or least interested news category. Another difficulty that science writers and reporters usually face in their daily routine is a “B.A pass Editor”. Since politics is a most trading product in the industry, it gives away to someone who has expertise in political journalism to become Chief Editor, and a science editor is compelled to work under him and a ‘Concept of Independent’ science editor is rare and exceptional.


Since our academia is not interested to pursue science communication as an educational field, it is hard for an editor, who didn’t study science as a subject of interest, to understand the significance of educating viewers about the advancements in the field of science and technology. Our country is lacking scientific approach in all aspects of life and media is equally responsible for it as well as our government.

Another difficulty, which science reporters have to counter is hunting for News. Pakistan is making no daily advancements, we rarely have some science or technology related news in our country. The last breaking news in science category from Pakistan was the launching of Pakistan’s remote sensing satellite and it happened back in July 2018.

Furthermore, Most of the private sector tech related news are killed (the term being used by news desk for the News story which can’t be aired or published) by marketing departments of media outlets, since they consider it as marketing stuff. Consequently, covering government sector tech related News is more difficult as most of our projects are being guarded by the military for security reasons, Like SUPARCO is under military control, so the reporters have to rely on the press releases only, which usually lack the scientific details.

Let’s have an overlook of Science writers and reporters. As Science journalism is not much rewarding field, so we rarely have a science writer who is specialized in scientific writings. Eventually, media organizations rely on people with good translation skills and these sort of writers usually become a curse in disguise. What they usually do with science and tech news is horrific story itself, like imagine, if someone is writing news of Enceladus –The  Natural satellite of Saturn and he never went through a single book on astronomy or even not fully aware about our solar system

Concluding the discussions on a happier note that the launching of an online astronomy magazine from Pakistan is like “a ray of hope in the darkness”. It should not the end of a journey but the beginning of the new start. It is quite obvious that in Pakistan, Science journalism has to cover a long journey barefooted and I have all my wishes and support with “Scientia magazine” and its founding and editorial teams.

The Mysterious Theories of Black and White Holes

0

Black holes have been a mystery for the scientists for a long time. There are many theories about black holes as well as white holes. Before going into detail let’s first define what the black holes really are. A black hole is a region of a spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole, so the black hole is a region of space-time where extremely strong gravity prevents anything, including light escaping from. We know that matterfalling into black holes is no different from the matter which can be found lurking around the rest of the Universe. Black holes have a finite lifetime due to the emission of Hawking radiation. However, for most known astrophysical black holes, the time it would take to completely evaporate and disappear is far longer than the current age of the universe.

Black holes have been a mystery for the scientists for a long time. There are many theories about black holes as well as white holes. Before going into detail let’s first define what the black holes really are
Black Hole

What are wormholes?

 According to the special theory of relativity, the laws of physics are the same for all non-accelerating observers and the speed of light within a vacuum is the same, no matter the speed at which an observer travels, so it means that a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole, which can only be entered from the outside and from which matter and light cannot escape. The theory of general relativity predicts that a sufficiently compact mass can deform space-time to form a black hole.

                   “White holes, which are theoretically the exact opposites

                   Of black holes could constitute a major portion of the

                      Mysterious dark matter that’s thought to make up most

Of the matter in the universe.”

What are wormholes? 

A wormhole is consistent with the general theory of relativity, but whether wormhole actually exists remains to be seen. A wormhole could connect extremely long distances such as a billion light-years or more, short distances such as a few meters, different universes, or different points in time.

Worm Hole

 Now we know the actual difference between black and white holes is that light cannot escape from a black hole and contrary cannot enter into a white hole. Another difference one might hope to exploit is that unlike black holes, wormholeshave no event horizon. This means that things could go in a wormhole and come back out again. In fact, theorists say one variety of wormhole wraps back onto itself, so that it leads not to another universe, but back to its own entrance. There are a couple of theories, let’s discuss them in detail.

Theory1:

White holes, which are theoretically the exact opposites of black holes, could constitute a major portion of the mysterious dark matter that’s thought to make up most of the matter in the universe, a new study finds. And some of these bizarre white holes may even predate the Big Bang, the researchers said.

Furthermore, Black holes possess gravitational pulls so powerful that even the light which is the fastest thing in the universe, cannot escape them. The invisible spherical boundary surrounding the core of a black hole that marks its point of no return is known as its event horizon.

A black hole is one prediction of Einstein’s theory of general relativity. Another is known as a white hole, which is like a black hole in reverse: Whereas nothing can escape from a black hole’s event horizon, nothing can enter a white hole’s event horizon.

Previously, researchers have suggested that black holes and white holes are connected, with matter and energy falling into a black hole potentially emerging from a white hole either somewhere else in the cosmos or in another universe entirely. In 2014, Carlo Rovelli, a theoretical physicist at Aix-Marseille University in France, and his colleagues suggested that black holes and white holes might be connected in another way: When black holes die, they could become white holes.

       “The dark matter is invisible; it does not emit,

    Reflect or even block light. As a result, dark

         Matter can currently be tracked only through

             Its gravitational effects on normal matter, such

As that making up stars and galaxies.”

Theory2:

Black holes nowadays are thought to form when massive stars die in giant explosions known as supernovas, which compress their corpses into the infinitely dense points known as singularities at the hearts of black holes. Rovelli and his colleagues previously estimated that it would take a black hole with a mass equal to that of the sun about a quadrillion times the current age of the universe to convert into a white hole.

However, prior work in the 1960s and 1970s suggested that black holes also could have originated within a second after the Big Bang, due to random fluctuations of density in the hot, rapidly expanding newborn universe. Areas, where these fluctuations concentrated matter together, could have collapsed to form black holes. These so-called primordial black holes would be much smaller than stellar-mass black holes, and could have died to form white holes within the lifetime of the universe, Rovelli and his colleagues noted.

However, even white holes with microscopic diameters could still be quite massive, just as black holes smaller than a sand grain can weigh more than the moon. Now, Rovelli and the co-author of research Francesca Vidotto, of the University of the Basque Country in Spain, suggest that these microscopic white holes could make up dark matter.

What is Dark matter?

Although dark matter is thought to make up five-sixths of all matter in the universe, scientists do not know what it’s made of. As its name suggests, dark matter is invisible; it does not emit, reflect or even block light. As a result, dark matter can currently be tracked only through its gravitational effects on normal matter, such as that making up stars and galaxies. The nature of dark matter is currently one of the greatest mysteries in astrophysics. The local density of dark matter, as suggested by the motion of stars near the sun, is about 1 percent the mass of the sun per cubic parsec, which is about 34.7 cubic light-years. To account for this density with white holes, the scientists calculated that one tiny white hole — much smaller than a proton and about a millionth of a gram, which is equal to about the mass of “half an inch of a human hair,” Rovelli said — is needed per 2,400 cubic miles (10,000 cubic kilometers). These white holes would not emit any radiation, and because they are far smaller than a wavelength of light, they would be invisible. If a proton did happen to impact one of these white holes, the white hole “would simply bounce away,” Rovelli said. “They cannot swallow anything.” If a black hole were to encounter one of these white holes, the result would be a single larger black hole, he added.

As its name suggests, dark matter is invisible; it does not emit, reflect or even block light.
Dark matter

Theory3:

The Black holes are common in the cosmos—nearly every large galaxy harbors a supermassive one in its nucleus, not to mention smaller specimens. However, astronomers have yet to identify a single white hole. That doesn’t rule out their existence entirely since it might be hard to see one: If they effectively repel particles, there’s a small possibility they could be lurking out there somewhere, invisible. Nevertheless, none of all the diverse objects astronomers have observed seem to resemble what we’d expect from white holes.

An even larger problem arises when we consider how white holes could form. Black holes are the end result of gravitational collapse. When a star at least 20 times the mass of the Sun exhausts its usable nuclear fuel, it can no longer produce enough energy to balance the inward force of gravity. At that point, the core collapses on itself, reaching ever higher densities until its gravity is so intense that not even light can escape. That results in a black hole with a mass comparable to a large star. Supermassive black holes, which are millions or billions of times heavier than that, form by some currently unknown mechanism.

 In any case, they still are the result of the gravitational collapse, whether from a huge super-star born in the early days of the Universe, a huge cloud of gas at the heart of a primeval galaxy, or some other phenomenon. Forming a white hole, however, would require something akin to a gravitational sewer explosion, and it’s not clear how that sort of event could ever occur. One possibility is that white holes might be “glued” to black holes. In this view, a black hole and white hole are two sides of the same thing, connected via a wormhole, a concept familiar from many science-fiction stories, a similar principle proposed for a “warp drive”—but no evidence for such material exists.

Conclusion:

 A probable conclusion of the above discussion is that our Universe contains a multitude of black holes but no white holes. That’s not because of a fundamental asymmetry in time—general relativity still works just as well either way time flows—but due to the nature of gravitational collapse: It only works one way.  This parallels the situation with the entire cosmos: There was a Big Bang, an initial expansion of all we observe, apparently from a single point. But the evidence points pretty strongly against the possibility of a Big Crunch, a re-collapse of all we observe into a single point sometime in the distant future. If current trends continue (specifically if dark energy doesn’t drastically change its character), the Universe will continue to expand forever at an ever-faster rate.

Just because the equations of general relativity allow white holes and big crunches, warp drives and wormholes doesn’t mean these things actually exist in nature. The asymmetry of time in gravity isn’t inherent but seems to arise from the behavior of matter and energy: gravitational collapse at the end of time, initial expansion at time’s beginning. The deep meaning of that is something physicists are still trying to comprehend.

FIRST MAN: MOVIE REVIEW

0

One of the most memorable and amazing films of the past year was “First Man”. Directed by Damien Chazelle starring Ryan Gosling and Claire Foy, this film explores the life of the first human to step on the moon, Neil Armstrong, thus aptly named. The film is a spectacular feature and a great addition to the science fiction genre. In Hollywood these days, where superhero franchises rule the box office, this film seems to be a breath of fresh air telling the story of a real-life hero.

After the end of World War II, the cold war continued between two giant superpowers i.e. America and The Soviet Union. One of the races was to become the first country to land on and explore the moon. The film highlights this issue in the beginning, showing the struggles and the journey of the American Space Program and their approach towards the achievem-ent of this certain goal. However, as this movie is based on the life on the life of Neil Armstrong, it starts with the depiction of his personal experien-ces that greatly affected his life. It is no surprise that it showed how the death of Neil’s daughter had a traumatic impact on his life, and afterwards, he became much soberer and more serious. He was a quiet man who had a brilliant mind, evident through his repeated selections in space programs by NASA.

st memorable and amazing films of the past year was “First Man”. Directed by Damien Chazelle starring Ryan Gosling and Claire Foy, this film explores the life of the first human to step on the moon, Neil Armstrong, thus aptly named.

Neil was selected to be in the team of the three people who would go to the moon in the Apollo 11 Mission. The other members were Buzz Aldrin and Michael Collins. However, this historic feat was not achieved in a single year, rather it took many years and even lives to shape and develop a perfect program. Neil’s competency was never argued and rejected as he performed exceptionally well at each step. In the movie, a melancholy tone gripped the entire plot which would surely intrigue the audience and keep them interested till the end. It also showed the views of the Americans who were critical of the program and NASA itself.  

The script was written by Josh Singer and was based on the book First Man: The Life of Neil Armstrong by James R. Hansen. What I loved about the film was it’s out of the world music by Justin Horowitz, the Academy award-winning composer of films like Whiplash and La La Land. It was the fantastic tunes and melodies that wonderfully complemented each scene and made it even more stunning. At times it was satisfying and at times it was beautiful enough to take your breath away. The final moments of the film showed the true compassion and nature of Neil Armstrong, who was previously presented as a rather calm and reserved human. One scene was so well crafted that I am sure it’ll bring tears to the viewer’s eyes.

Unfortunately, the film suffered some major setbacks in the box-office as well as the general audience in the USA due to some controversies. Some argued that this film should’ve discussed more aspects of the Apollo mission to the moon and should’ve included more stories and people. The major trouble was created when people said that it was very wrong not to include the moment when the American flag was placed on the lunar surface. Ryan Gosling, the lead actor, said that it was not the story of the Americans but a hero who was human and who didn’t care any less about the flag. He said that it was an achievement for the whole humanity, and it would contradict the famous words of Neil himself that were, “This is one small step for man, one giant leap for mankind”.  Also, this film included several of his famous quotes including the iconic phrase, “Houston, Tranquility Base here. The Eagle has landed”.

Ryan and Claire Foy performed exceptionally well and brought life to their characters.

The movie had amazing cinematography, direction, soundtrack and acting among other things. Ryan and Claire Foy performed exceptionally well and brought life to their characters. The supporting cast was also great and the director Damien Chazelle, just like his other hit movies, proved that he would soon stand out in the line of best directors of the century. Visually, the efforts of the editors and visual effects artists must be appreciated as replicating the landing wasn’t as an easy step as it sounded. Every department did their best. Certain moments may bore those having a short attention span but can be compensated by other stupefying bits. Neil Armstrong’s sons also applauded the movie and it’ll be remembered in the years to come as a masterfully crafted work of art.

It is a daunting task to portray such a hero but, in my opinion, it was a job well done. Portraying human emotions, a historic scheme, and a dangerous expedition needs skills and work which was aptly done by the entire team of this film. It will certainly inspire many who like to dream big and work hard while facing extreme personal issues. It is a lesson that if a human possesses humility and commitment, nothing can stop from him/her from going to the moon and back. Literally!

COVER STORY “Nancy Grace Roman”

0

Mother of Hubble Telescope

Who would have thought that this little newborn baby girl born in Nashville, Tennessee would defy all odds and rise to the challenge what nobody ever thought was possible in that era? The girl like most women in the sciences in the mid-twentieth century would have to face the male dominance to pursue a role in science and technology where these roles were perceived as inappropriate for women in that time period but unlike many women discouraged by the odds, she continued to be resilient and thus Roman’s scientific legacy was hard-won. She emphasized on science subjects despite discouragement from teachers and professors. And during her career, she faced gender-based discrimination when science was largely dominated by men, but her persistence paid off, and she became the first woman to hold an executive position at NASA before retiring in 1979. The Roman’s crowning achievement at NASA was perhaps the greatest gift ever given to astrophysics: the Hubble Space Telescope, the groundbreaking satellite observatory that has helped in more than 1.2 million observations and 14,000 research papers since its 1990 launch.

Nancy Grace Roman was born in Nashville, Tennessee on May 16, 1925, the only child of Georgia Smith Roman, a former music teacher, and Irwin Roman, a geophysicist. Because of her father’s job, the family moved various states around the US like Oklahoma, Texas, New Jersey, Michigan, and Nevada. Once Roman memorized her childhood days when her mother had taken her outside in Michigan and introduced her with the natural world and pointed out specific birds, plants, and animals. Georgia Roman often showed her the constellations and the northern lights in the night sky. At the same time tried his best to provide the answers to her queries about the natural world in a precise scientific manner that helped to grow her early interest in nature and celestial objects.

“Who would have thought that this little newborn baby

It was because of her parents’ efforts that Roman organized her own astro-nomy club at the age of 11 with her neighbors and friends, where they used to hold weekly meetings to learn about the constellations. Though her great passion for scientific subjects she very often met with resistance, if not out-ward contempt. Once she recalled her early days when her high school guidance counselor insisted that if she could take second-year algebra ins-tead of Latin? And very identical sort of reception I met with most of the way out. The only encouragement she had gotten during her graduation was by a nice teacher of hers, who told that more often she tries to discou-rage girls from majoring in physics, but she applauded Roman’s passion in science and show her confidence that she will certainly make it.” 

Despite the doubts that surrounded her scientific ambitions, Roman fought to receive secondary education in astronomy and physics. As a promising student at Swarthmore College, Roman still had paid no attention to the warnings from the Dean of Women education about studying science and ultimately earned her B.A. in Astronomy in 1946.

After graduating with a BA in astronomy in 1946, she graduated from the University of Chicago, even though the professors clearly did not like educating women. Moving to the University of Chicago, she earned a Ph.D. in astronomy three years later and joined University’s Yerkes Observatory as a researcher. However, spending six years of professional success at Yerkes, she was not satisfied with her career achievements and future. Neither she was a permanent staff member and nor hopeful to be in future since she could see that those positions were overwhelmingly offering to men.

Eventually, in 1955 she met with an astronomer who needed for the US government’s naval research laboratory in Washington, DC. She applied for and got the job. Four years later, she was tipped off that the recently formed NASA was looking for someone to set up its space astronomy program. She earned that position, and finally, at NASA, she got a place where men treated her as an equal without gender discrimination.

Hubble Telescope Program:

In fact, the idea of the Hubble Telescope can be traced back to 1946, initially, it was astronomer Lyman Spitzer who published his research paper titled as “observatory”. But due to concerns over the costs of such a telescope and doubts that it could even be executed, the plan to get such an instrument into space did not take off for a decade.

 In 1959 Nancy Joined NASA, just six months after the agency opened, Roman was in-charge of developing a program of astronomy from space. She traveled the US talking to astronomers in their various universities and listening to their ambitions. She also went in lengthy discussions to elaborate the advantages of observing from space, where there was no atmosphere to blur the view and no daytime to halt the observatory’s work for half the day. In 1960, she successfully arranged meetings of around 30 astronomers and NASA engineers to discuss the idea of a large, general-purpose space telescope that in order to come up with something that could sense to everyone, she acted as the interpreter for these groups of engineers and astronomers. The real hurdle lies in a heavy budget since it cost 20 times the price of the largest ground-based telescope.

Eventually, with her great efforts, she laid the foundation, but it took until the 1970s for certain key technologies to be developed, like the CCD chips that made the first digital cameras possible. Once these were available, Roman set up the program that built the Hubble space telescope. It was too laborious and by the time the telescope was launched in 1990, Roman got retirement from NASA after 11 years of hard work and dedication and joined as a consultant and an advocate for women in science. 

This is because of her great contribution, she often is called the “Mother of Hubble”. Initially,

It was Edward J. Weiler, the [then] chief astronomer of NASA who worked with Roman at the agency first, called her ‘the mother of the Hubble Space Telescope’. Once he paid a great tribute to Roman that “we are regretful that history has forgotten a lot in today’s Internet age, but it was Nancy in the old days before the Internet and before Google and e-mail and all that stuff, who convinced the US Congress to fund such a huge project, organized the astronomers around the country that led to the launching of Hubble Space Telescope,

Research and Contributions:

Though many might consider Hubble to be her greatest legacy, Roman herself once told National Geographic that she was proudest of two things. During her time at Yerkes, Roman discovered that stars on circular orbits with more heavy elements are younger than those with more random orbits and fewer heavy elements. She also observed BD+67 922, a star that would later be renamed AG Draconis. Roman’s groundbreaking research on stars helped and motivate others to explore the evolution of the galaxy, and the International Ultraviolet Explorer, which facilitated over a hundred thousand observations of the stars.

 Her other Work Included in the Astrophysical Journal Supplement Series was a catalog of high-velocity stars. She documented new “spectral types photoelectric magnitudes and colors and spectroscopic parallaxes for about 600 high-velocity stars”. Roman also wrote a paper on the detection of extraterrestrial planets and also discovered that stars made of hydrogen and helium move faster than stars composed of other heavier elements. Moreover, during her early research, she found that not all stars that were common had the same age. That was later proven by comparing hydrogen lines of the low dispersion spectra in the stars.

Legacy:

Roman’s role as an advocate was not limited to the Hubble, she sought to inspire young people, and particularly girls, to pursue careers in the scientific fields. After getting retired, she taught astronomy to fifth graders in Washington. She advised to students who interested to pursue a career in science that science or engineering can be a great field for you only when you enjoy puzzles because scientific research and engineering consists on a tedious series of solving puzzles. Science, like all jobs, has its share of drudgery and boredom for many but basically, it is fun.
