LETTER FROM THE EDITOR Welcome to the second edition of Hubble. Countless hours and sweat went into this edition, but at the end - we are so proud of it. This time, we tried to make more of a conscious effort to make our articles easier to read, understand and enjoy. Some topics, like diversity, are meant for serious conversations and we reflected long on this and decided that if we have a platform it is our responsibility to use it for the better. This edition, we put a focus on diversity in STEM, an issue that has plagued the industry since it began. With opeds regarding women in engineering, and focusing on pioneers in STEM, we hope that some light can be shed on this issue. Together, as we work towards making the world a more diverse and inclusive place, it is crucial to honor those who paved the way for us. Due to this, we as a team have decided to do a profile on an individual in STEM who has broken all the barriers and proven themselves to the world every edition. For this edition, we will shed a light on the life of Katherine Johnson - a black woman in STEM who is a true trailblazer. I would like to thank everyone who came together in order to make this edition a reality, this would not have been possible without you.

STRING THEORY GURSIMAR KUMAR

What is it?

Before reading the rest of the article, take a look at your hand. Maybe turn it around a couple of times, open and close your hand, observe the curling of the fingers and the arch of your wrist. Bring it closer and closer to your face until you see the lattices of your epidermis, skin tensing around the knuckles of your bones. Now, this is far as the human eye can see, but if you use a microscope, you’ll see molecules. With an even more precise transmission electron microscope, you can image atoms. From there, you can zoom in even further and see electrons, and the nucleus with neutrons and protons can be zoomed into even further until you see quarks. Now, this is as far as conventional science allows you to go. If you zoom into a quark, you will find nothing but the mass of the quark or empty space. There’s another theory, though, one that says if you zoom in even further, you will see a string. Just a string. A tiny thread of energy that makes up the entire universe. That’s string theory in a nutshell. Lots of strings of energy, similar to the strings on a guitar or a violin. Zoom out all the way again; the hand that you’re looking at is made up of millions of billions of billions of billions of strings. The same goes for the rest of the universe. Not a group of flying, swarming charged particles, but one big beautiful orchestra that makes up everything we know and everything we don’t.

HUBBLE THE MAGAZINE

Why are these strings so important and so controversial to the scientific world right now?

To understand the answer to that question, we have to know the two other most important theories in science right now. Quantum theory, breaks down the nature and behaviour of particles on an atomic and subatomic level, and the theory of relativity states that gravity isn’t some invisible force that pulls things together, but a warping of space itself. If that doesn’t make sense, try and imagine putting a bowling bowl on a waterbed. That waterbed is the entire universe, and the bowling ball is maybe the Sun. If you roll a ping pong ball across the waterbed, it will roll right across with hardly any diversion from its path. However, if you put a bowling ball in the middle of this bed, the course of this ping pong ball curves around the bowling ball, because of its mass. The only catch with these two brilliantly posed theories is that they seem to contradict each other. There is no math with what we know that unifies the laws of the subatomic universe and the laws of the larger forces of the universe. String theory provides the math that makes the two work together, by adding six more dimensions to the four-dimensional universe around us. String theorists propose that these extra dimensions are so small, we cannot see them with our eyes or specialised tools, or even identify them with our extremely high energy experiments, and that they are necessary to give the strings that make up this universe the room they need to freely vibrate in the ways they do to create the matter and energy in this universe the way it is. String theory is one of many potential candidates for the Theory of Everything. It is the most praised and the most criticised. It is praised for its mathematical beauty and just how perfectly everything seems to fit. It is the most fleshedout candidate, and it is the only one that reconciles the micro and macro laws. However, it is heavily criticized since it just cannot be proven. In fact, some scientists have gone so far as to say that it doesn't even meet the base requirement of a scientific theory, the ability to be proven wrong.

HUBBLE THE MAGAZINE

Is there really no way to prove this theory at all?

Technically, there is a very, very expensive way of testing this theory. Approximately half a million years after the Big Bang, the universe was primarily made up of neutral hydrogen atoms, coupled with the radiation from the original explosion. String theorists predict that some cosmic strings existed at the time, leaving slight fluctuations in space around them, leaving behind some kind of mark on those basic hydrogen atoms, absorbing radiation at a wavelength of precisely twenty-one centimetres. However, due to the 14 billion years of expansion, the wavelength of that radiation would have surely stretched to approximately twenty-one metres before reaching Earth. By creating a wide array of telescopes with a total area of more than a thousand kilometres, we can identify the cosmic footprints those strings left behind. So while testing this theory out doesn’t prove to be impossible, it would cost more than the annual GDP of every country in this world.

So if it can’t be proven right or wrong, why is Hubble writing about it?

Simply because we may not be able to prove this theory right or wrong right now doesn’t mean that we will never be able to do so. Thousands of scientists worldwide are finding new ways every day, and with the rate at which our technology and our ideas are evolving and expanding, we might find a way very soon. This theory presents incredible possibilities for our universe. The entire visible Universe could be a hologram, merely an illusion that is isomorphic to the information on the surface of the Universe. This theory also backs the idea of the anthropic principle, that uses the existence of human life as an explanation for the natural constants in our Universe. It even opens doors that there are possibilities of infinite universes, either parallel or completely different to ours. A grand cosmic heavenly symphony of strings playing a grand sonata, where our little planet, perhaps the only one with life, plays a sweet little melody, getting closer and closer to figuring out the rest of the piece.

HOW ENGINEERING FAILED WOMEN ADITI GAUR

Disclaimer: Before reading this article, please note that this article speaks to

the majority of the people that go into this field. There are most definitely exceptions, but this speaks to the data. Meet the most male dominated field in STEM - engineering. Only 13% of engineers are women in the US. While a lot of schools and organizations are taking steps and reforming curriculum to be more inclusive of the gender, it’s needless to say that this issue is far from solved. Most of these curriculum reforms happen in schools, and to some extent, have worked well. While more women are coming in to study engineering, the problem is that many quit either during or after school. While focusing solely on education, we have turned our backs to the issue that these women leave this profession at a much higher rate compared to men. 20% of engineering graduates are women, but estimates suggest that almost 40% of them either quit pursuing their degree, or choose to not enter the workforce once graduated.


Very often when I have talked about this issue, people make similar statements like “Women tend to drop out since they don’t have the willpower and work ethic to make it in this field.” “Women tend to naturally not be interested in fields like engineering, so studying it felt forced to them. Thus, they drop out the first chance they get.” “If they dropped out after having the opportunity, that’s on them. Women just aren’t cut out for this field.”

These ignorant comments are harmful, since they are so misinformed about why women actually drop out and the fact that this issue is resolvable. It’s high time to inform people who make such comments with actual facts and reasons that lead to this situation. Carroll Seron (UC Irvine), Erin Cech (University of Michigan), Brian Rubineau (McGill) conducted a research study of engineering students to learn about the culture they face, and how gender plays a role in that. The first thing they found was that female students did either as well as their male counterparts, or better in school - which proves that the idea that women don’t have the work ethic or the brains to make it in engineering is invalid. Looking at why they enter the field

The study found that both male and female students had, more or less, similar reasons for enrolling. They were described as being good at science and math in high school and wish for well-paid career opportunities later down the line. A difference found between the two is that - more often than men, women reported that they want to use their engineering education to solving major problems and contribute to making a difference in people’s live - this is also consistent with research by other which shows that women tend to be more ‘socially conscious’ compared to their male engineering counterparts.

HUBBLE THE MAGAZINE

|

23


As time goes on, women and men are both equally successful in their classroom. However, as time passed, they noticed that women started to doubt their problem-solving skills and lack self-confidence - which they previously didn’t. Why do they start leaving the field?

It is important to understand that every profession has its own culture and values, ideas that make it unique. For most women engineers, this culture works against them. Their first encounters with engineering are tied to gender stereotypical ones, usually by their own peers. Collaboration is a major part of this field, and so many women have had negative experiences with it. When working with their male peers, they are often made to feel excluded and forced to do more ‘secretarial’ jobs and being kept away from the ‘real’ engineering work. A lot of these women found themselves in situations where they would work hard on a project, and their male peers would join the group and quickly sentence them to do more unskilled work, taking much of the credit. A lot of them also report being treated differently by professors. Rachel, a participant in the study, said that once she was in an all-girls team and won second place in a design competition, when her team was asked to pose for a celebratory picture, their professor said: “You guys look like professional catalog models; this picture could go in a catalog and you could sell big time.”

HUBBLE THE MAGAZINE

|

24


Comments like these, obviously, make women uncomfortable. Meanwhile, the male students in the classroom reported much more positive comments about group projects, and how much they enjoyed working on them. Exposure to the workplace

Most students intern in the fields they are pursuing - to gain more exposure to how their career will look in the future. It was found that in these internships and opportunities, men were assigned more problem solving tasks which would allow them to develop their skills, meanwhile women were assigned tasks such as - sorting paper, writing notes and coordinating - which they said did not make them feel valued or develop their skills in any way. Almost all male students reported their experience in the internship to be positive, and it was not like that for the female students. While there were some women who spoke highly of the opportunity they got, the variation in responses was much greater compared to their counterparts. Aurora, a participant in the study said “The environment was creepy, with older weirdo man engineers hitting on me all the time and a sexist infrastructure was in place that kept female interns shuffling papers while their oftentimes less experienced male counterparts had legitimate engineering assignments.”

A lot of these women also reported they would be treated as if they did not have any knowledge, and wouldn’t be taken seriously. While they did say that not everyone did this, it was a fair amount of people, and most of these people were old men. If this culture of stereotyping and sexism is not addressed urgently, smart and capable women who can accomplish so much will be forced to drop out of the field they love. The culture of engineering needs to be reformed from the root and the people who are already in the field need to be at the forefront of it. An occupation that is so glorified for its problem solving skills fails to find a solution to this colossal problem, and honestly, doesn’t seem to care.

BENFORD'S LAW AND TAX EVASION ADITI GAUR

Warning: this article may or may not blow your mind. It also may or may not contribute to convincing you that we are all a simulation. Reader’s discretion advised. First off, what even is Benford’s Law? Every single user on Facebook has a certain number of followers. So, imagine that is your data set, a list of the number of everyone's followers. the first digits of that data, the leading number, for every element in that data set will begin from 1-9. Typically you would assume that the first digits of that data ranging from 1-9 will have equal occurrences of each number, with roughly an equal number of elements having a leading digit of the number 1, equal with the number 2, and so on. Except, that’s not true. Benford’s Law refers to the distribution of the leading digits in an economic data set. It is an observation that, despite what you might expect, in a data set that has not been intentionally uniformly distributed, the occurrence of the digits 1-9 as the first leading digit are not equally likely. Instead, the probability of occurrence decreases with an increase in number. To understand that better, 1 as a leading digit will appear around 30% of the time, while 9 as a leading digit will appear approximately 4.6% of the time, this is called the Benford’s Curve (Fig 1).

Fig 1. Benford’s Curve

Getting back to Facebook followers, the data set of the number of followers everyone has will follow Benford’s Law, with 30% of people having followers starting with the number 1, about 17% with the number 2 and so on. Studies found that it doesn’t only apply to Facebook but also to Twitter, Google Plus, Pinterest, and LiveJournal. To further blow your mind, this law even applies to the number of posts users make, and even describes the price distributions in eBay auctions! Here’s the results from the research study looking at online social networks and Benford’s Law (Fig2):

Fig 2. Distribution of first digits for Twitter, Google Plus, Pinterest followers, Facebook and LiveJournal.

Here’s why this is useful:

While studying data from social media accounts to see if it follows Benford’s Law, they found some users deviating very strongly from this law. Out of 20,000 Twitter accounts analysed, the 100 users who were farthest from this law were all found to be engaged in suspicious activity. This opens a possibility for this law to be used to detect irregular behaviour on social media, like bots. It can also be used to validate samples in datasets from social media. So you never know, if all goes well, you might not have to complain about these annoying bots on Instagram in the near future.

Background on Benford’s Law

In the 1880s, an astronomer, Simon Newcomb, first came about what is now called Benford’s Law. He was looking at a book with logarithm tables and noticed the tables in the front pages of the book, where most numbers would begin with 1, had more wear than than the back, where numbers would start with nine. Using this observation, he calculated a probability formula. Later on, Frank Benford, a physicist, noticed the same thing. To validate this observation, he collected data sets from various sources: atomic weights, the surface areas of rivers, numbers appearing in Reader’s Digest etc. Soon, a pattern was established - Benford’s Law. What is perhaps even more intriguing is the fact that this law holds across change in measurement units. Temperatures that follow Benford’s Law will follow if it is measured in Celsius, Fahrenheit, or Kelvin. Distances will follow it regardless of whether they are measured in miles, kilometers, or yards. Tax fraud?

If you’re wondering how tax fraud fits into all of this, here’s how. As you might know, what bad rich people tend to do a lot for some reason, is tax fraud. Tax fraud is when a person or a corporation puts fake numbers on their tax returns in order to decrease the amount of tax they have to pay or to avoid it altogether. When someone creates fake data, the chance of the first digit being between 1-9 is generally 1/9. This, as we know, is not generally true with naturally occurring data due to Benford’s Law. Tax agencies - such as the IRS- can use this information to their advantage by using the law to spot numbers that deviate from the curve. It is important to note that simply because something is not following Benford’s law does not guarantee that something fishy is going on, but it provides tax agencies a way to spot potential wrongdoing, a clue on where to look. We believe that every individual is unpredictable, and all of us exercise free will, but in the long run, we all seem to fit into this curve made by some guy named Benford. HUBBLE THE MAGAZINE
