I rushed mine, to the extent that my supervisor mentioned it to me a few years later... it was a reflection of my state of mind at the time, exhausted and overwhelmed.. if I ever get around to doing another one I'll give it the attention and love it deserves

despite having a phd in nonlinear dynamics, I struggle to wrap my head around most of this stuff... but I always found is deeply fascinating.

In one system I studied we had a sequence of period doublings, which followed one of the feigenbaum constants[1]

seeing this happen in the lab, and subsequently seeing it numerically, and uncovering the analytics behind it was a worthy use of 6 years

the extensibility of matplotlib is simply incredible to me. I've always found the main limiting factor to be my imagination, once I wrap my head around what I want a plot to look like I know matplotlib will facilitate it. An absolute marvel, and a credit to the devs

exact analytical solutions are nice as a check against any numerical solutions imo. (checking the same calculations in multiple ways is handy for error catching ime)

because it's really hard, and they need to publish :)

Having spent ~6 years studying nonlinear laser dynamics, it always amuses me to see bifurcation theory pop up on HN.

A fantastic resource on a lot of this material (basically a peer reviewed wikipedia): http://www.scholarpedia.org/article/Bifurcation

doing the math is seldom enough ;)

*KE == kinetic energy

kinetic energy: "energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes."

in normal person terms: the energy of moving, or ~exercise, in a parallel world :)

anonymous messages are sometimes very powerful, measurements that are easy to make are not necessarily the right ones to make

a spectacularly unbiased example, multiple measurements, experimental and simulated, of the same thing :)

Using a term like nonlinear science is like referring to the bulk of zoology as the study of non-elephant animals.

I think this is the paper, which oddly isn't linked in the article:

matplotlib. at times it can be tiresome, given the multitude of ways it's possible to do things, but it's always possible

I've only made two submissions. By some odd coincidence both made it to #1, which has scared me off making any further submissions for fear of ruining my perfect score! :D
