| firsty.mp4 | Something is better than nothing.
|
| first.mp4 | Learning about the variable known as time.
|
| second.mp4 | Nice, it's sinusoidal! 0-dimensional.
|
| third.mp4 | A sine in 1-d.
|
| fourth.mp4 |
2-D Sine varying with x and y (and time, shown on z) rectilinearly.
|
| fifth.mp4 |
2D but varying with radius not x & y. Equal energy in each ring.
|
| sixth.mp4 |
Semi-3D: 2D wrapped around a sphere. Not equal energy but equal amplitude rings
(small rings have less total energy).
|
| seventh.mp4 |
Equal energy in each ring, again.
|
| eighth.mp4 | One going
up, another going down, add them together at the same time, you
get a standing wave.
|
| ninth.mp4 |
Two standing waves with different energy levels, different axes
on the sphere, different time frequency, different spatial
frequency. (There's an absolute value in there to fix: see the
discontinuity at one of the equators.
|
| tenthy.mp4 |
Fixed the absolute value, included some frames from a different
run by mistake.
|
| tenthish.mp4 |
This loop is periodic on the vertical standing wave, but not on
the diagonal wave, which jumps 180 degrees at the loop instant.
|
| eleventh.mp4 |
There we go. Two cycles on the vertical for three cycles on the
diagonal. Still equal-energy rings. Pine-cones and coronaviruses
aren't so polarly-peaky.
|
| twelfth.mp4 |
That's getting closer to a pine cone.
