can a fourier transform be done in 3 dimensions with a sphere that also vibrates?

light is an oscillation of the electromagnetic field.

imagine stretching a spring out. this is represents an electromagnetic field. imagine flicking that spring. the vibration caused to the spring is light, and the frequency at which it is bouncing around is the light frequency. In this example this is non polarized light.

5^x ≅ 1 (mod 4)

My mind was blown when I produced this for an unrelated math problem.

proofs?

5 ≅ 1 (mod 4)
5^x ≅ 1^x (mod 4)
1^x = 1
∴ 5^x ≅ 1 (mod 4)

This blew my mind

I want more like these.

Math/Science gifs please.

Will dump a few that I got.

This is explains Gibbs phenomenon if you look at the spikes at the end of each wave.

Do you think there's a way to algebraically find the number of solutions of sin(kx) = x given the value of k?

assuming this is true, would this mean that gamma rays given off by nuclear fusion would be able to be directly converted to electricity instead of first being converted to mechanical then to electricak energy?

this one is a way of visualizing Fourier Series

can't wait to see some cool new ones!

Why is the potential energy of a harmonic oscillator (1/2)*k*x^2 where k is the spring constant?

Can somebody explain/derive it for me? Maybe the kinetic energy as well, please.
