Honestly, I have no idea what this actually means, it's something about electrical circuits in a solar panel, I just did the cool 3D visualisation...

Suggestions always welcome!

Both Bode and Nyquist plots are used to determine whether a system is stable, and in that case, how robust it can be, at various frequencies of the input variable.

There is a LOT of math (differential equations, matrices, eigenvalues, complex numbers, Laplace transforms...) behind these, it's quite interesting.

The craziest part of this to me is that in my current math class we’re going to cover everything you mentioned. We’re covering eigeinvalues on Wednesday and laplace transformations later. I’m so excited to get into these higher level math topics! Mechanical vibrations was so cool.

Well, dynamical systems are everywhere, and if one studies engineering/physics/maths... They will be covered.

Really cool animation. I would almost prefer it to be slowed down but it's great stuff!

Can you explain this for us dumb people

Excited about these beautiful curves in 3d. What does it all mean?

Look at the big brain on Brad.

As someone who loves Control Engineering this is just like art. Outstanding job :)

I understand very little of what any of this data means, but I am quite proud of how readable the graph is. (with the exception of details like the freq axis ticks...)

In general, it is very hard to interpret a single line in 3D from just a static plot. Even with the 3 projections onto the 3 "walls", it's not easy to intuitively understand the shape of the line and how it behaves.

The regularly spaced vertical lines together with the semi-transparent fill make it surprisingly easy to just understand the shape, simply from looking at it. And basically from any direction.

There aren't too many real-life cases where you have a single line in a 3D space, but I'm definitely going to use this exact visualisation again if I ever come across one!
