One day you have a some problem and you know what your friend
Cauchy (of course, all my Russians friends have a friend with name
Cauchy) can help you to solve your problem. You invite them to your room and you together trying to solve a problem that you have. After few hours your friend
Cauchy says — "If I have *this* instrument, I could solve the problem". You remember that three days ago, your friend
Jacob told you that he had bought *this* instrument. You invite a
Jacob to your room and you all trying to solve your (seems to hard) problem. It seemed like the problem had almost been solved, but then
Jacobi says, ‘We've solved your problem, but it will only work if
Zermelo solves his problem.’ You call
Zermelo to find out how his problem is progressing, and he says — "Sorry, bro, my problem can't be solved in
ZFC, try another one."
It explains how mathematics works for me and why I love it 😌!Mathematics has grown a lot over the last thousand years, but the connections between different topics have stayed the same.
I think Geometry and Algebra are a great combination. The idea of using a coordinate system to solve geometric problems is very beautiful.
The second thing I found beautiful was the connection between number theory and analysis. Number theory seems to be something discrete, countable and simple, since we most often work with natural numbers.
Analysis, on the other hand, uses the language of infinitesimals and functions, which doesn't seem to match number theory at first.
To show how number theory and analysis are connected, I will give you three simple proofs of statements about prime numbers.
