Solving DEs is very important dude.

Also it gives some very important insights into Fourier series, which is also very important, even in your everyday life.

In what way

>>9040343
Is this an infinite space?

>>9040377
>In what way
Do you mean why Fourier series are important?
If that is the case just google a bit about electrical engineering and signal processing. Even mp3 is based on that shit.

How can somebody use a computer to write a question like this?

>>9040343
All of quantum mechanics and qft rests on functional analysis (and in some respects IS just functional analysis)

Kernel methods in machine learning

In the 1960s Friedrichs met Heisenberg and used the occasion to express to him the deep gratitude of mathematicians for having created quantum mechanics, which gave birth to the beautiful theory of operators on Hilbert space. Heisenberg allowed that this was so; Friedrichs then added that the mathematicians have, in some measure, returned the favor. Heisenberg looked noncommittal, so Friedrichs pointed out that it was a mathematician, von Neumann, who clarified the difference between a self-adjoint operator and one that is merely symmetric. "What's the difference," said Heisenberg

In conclusion, is garbage
