Most of the day today、I was watching YouTube。Last night I happened to see a video by Kantaro Suzuki called ``Understanding Euler's formula through junior high school mathematics.''。２、3It became a hot topic a year ago、There is a link to a book with the same title.。I had seen a glimpse of the book at a bookstore at the time.、It was around the time that the movie ``The Mathematical Formula That the Doctor Loved'' was becoming a hot topic.。Last year, Professor Shinichi Mochizuki of Kyoto University、It became an international topic of conversation for completely proving one of the most difficult problems in mathematics, the ABC conjecture.。Although it was quite a while ago、More than 300 years after Fermat's death、Even when it was announced that ``Fermat's Last Theorem'', famous as a historically difficult problem that no one could solve, had been completely proven.、The whole world was excited。There seems to be a bit of a mathematics boom in the streets in recent years.。
including me、There must be a lot of people who are not good at mathematics.。However, even such a person、Into the abstract and concise world of mathematics、It is not uncommon for people to have feelings similar to admiration.。Mathematics is the first step to science。What has been proven mathematically、No matter how much you like it or hate it、Even if you don't feel comfortable with it, you can't help but admit it.。If there is such a thing as truth, this is it.、We somehow think that。I don't understand that at all、Rather than being embarrassed、I even feel in my heart that it might actually be bad.。But、Even if I pull out my math book,、I think most people will give up again because this is so unreliable.。
That's、Euler's mathematics、It is said that the mathematical formulas of great geniuses in the field of physics can be understood with the knowledge of junior high school students.、It was stuck in the back of my mind.。If you watch the video, it's not like they only use mathematics up to junior high school students.、``If you have mathematical knowledge up to junior high school,、On top of that, explanations of trigonometric functions, differential and integral calculus, etc. are added to help students understand Euler's formula.。It is certainly possible for junior high school students with good understanding.、It was a simple and brilliant explanation that made me think (the content is not simple at all)。If you are interested, please take a look。"Prove that pi is less than 3.5" is a famous question for the University of Tokyo entrance exam.、It was subtle but very interesting。
With the flow、I also saw "Einstein's (Special) Theory of Relativity" by Takumi Yobi Nori (first time I heard about it).、This is also very well explained。I took classes like this in junior high school.、I think if they had done it in high school, I might have taken a slightly different path.、It can't be helped。corona、The world is sinking due to Corona、Moreover, the countermeasures are in a state of disarray.、Hayabusa will return to Earth properly.、The earth's rotation does not stop even for a moment。Don't just go back and forth depending on the phenomenon.、Those that do not change、A day when I felt that the world could become a little different by thinking about where we put our perspective.。
