Beautiful Questions

The last episode for Story of Maths was more on the unsolved puzzles of math, which is a collection of questions by David Hilbert. He had 23 problems, each was still unsolved during his time, and he challenged the future mathematicians to solve it one by one.
       The first problem was solved by George Cantor, who lived in East Germany. He was the first mathematician to fully understand infinity, which was amazing, because until now I find it hard to believe that a number such as infinity exists. It was cool the way he showed how to pair up the infinite number of fractions with the infinite set of whole numbers. Apparently, there are infinite infinities, each having a somewhat different size. A problem he had thought was whether there were infinities sitting between two other sets of infinities.
            The next mathematician discussed solved how 3 heavenly bodies could move in a stable orbit, so that he could receive the prize from the king of Sweden who asked the problem. However, before publication, as mistake was found in his work. This mistake was important for creating the chaos theory, which is currently part of the 20th century mathematics.
            I got interested in the next problem about the 7 bridges, because it was more of a puzzle than a problem. Leonard Euler proved that it was not possible to answer the problem, which kind of left me quite disappointed, because I was looking forward to the answer. This lead to the study of topology, which can also be called ‘bendy geometry’, since it states that if one object can be morphed into another without cutting it, they are topologically the same. It’s a really interesting thing to know about, because I do want to know how a bagel can be the same as a tea cup.
            David Hilbert was an interesting mathematician, and sometimes referred to as the most charismatic mathematician of his time. What intrigued me was his problem. He was able to prove that there is a finite set of equations, but he cannot somehow construct it. Hilbert was a very interesting mathematician; a proof of this is when he collected his favorite problems which math has not solved yet during his time. They became somewhat a foundation of mathematics, and so many mathematicians have been dedicating their lives to answer one of the 23 puzzles.
            Another interesting mathematician was Kurt Godel, who was somewhat odd. During his time, he loved to stay in cafes, pretty much like what we do. Here, in his discussions with the Vienna circle, he stated on how he wanted to solve Hilbert’s 2nd problem, but instead he proved he opposite of it. There can be mathematical problems which are true, but cannot be proved. It was like the sentence: I always tell a lie, wherein you can say it is true but you cannot prove it. It somewhat made him feel blue.
            Due to the raging Nazi wars, a lot of European mathematicians fled Europe and came to America, where the Institute for Advanced Study was waiting for them. Here, a lot of famous mathematicians thrived, and one of those was Albert Einstein himself. Kurt Godel also went to the institute, and he became good friends with Einstein. Soon, Kurt Goedel gave into depression. During those times, a  younger American mathematician was making his way to the top.
            Paul Cohen was young when he first loved math. At the age of 22, he was able to find a solution for Hilbert’s first problem; that there could be a mathematics where the continuum hypothesis was true, and the other mathematics where the continuum hypothesis was false. No one believed him that much, but after Kurt Goedel said yes, his answer was correct, he received a lot of fame and money. I can’t believe being a mathematician could actually make you earn money. Sometimes, I wonder what it would be like going to the same institute as they had. It would’ve been fun and at the same time, could induce a lot of pressure due to the presence of the many highly intellectual people.
            It really made me quite proud that there were female mathematicians who also rocked the mathematics world. One of them was Julia Robinson, who from a young age showed full potential in mathematics. She stayed in the University of California, found her partner, married and settled onto Hilbert’s 10th problem. Apparently, it was solved by Yuri Matiyasevich, who was 22 when he found the answer. It was sweet of him to thank Julia with all his heart, since she was his inspiration for solving the problem.
            Nicholas Bourbaki was another math star, for he had numerous books which were used as foundations. Apparently, he was not one person, but rather a group of mathematics lead by Andre Weil, who was a great Russian mathematician.
           At the end of the movie, I learned that out of all the 23 problems, the 8th one has not been solved yet: the Riemann’s hypothesis. Maybe one day, I would be the one to solve it. Maybe.
           All in all, the Story of Maths as a wonderful journey throughout the mathematical world. It was amazing how a lot of people contributed to form foundations for the subject, and how they just exchanged problems to be solved. It helped be somewhat appreciate math a lot more. I will be missing Du Sautoy though, because of how witty he is and how he was able to make me watch everything without getting bored. The adventures of math that we have gone through proved how hard yet enjoyable it is, despite the fact that it sometimes caused depression and paranoia. Still, I grew to appreciate math more, and hopefully I will continue on to appreciating it, or maybe be able to solve problems that have never been solved before.
