Sneak peek for an upcoming video
Added 2018-10-31 22:13:07 +0000 UTCHere's quick clip I wanted to share. It involves taking a laser, diffracting it through a small glass rod so that the light is spread along a plane, and shooting smoke rings through that plane.

2018-11-03 07:17:15 +0000 UTCI would really value on an exposition on solitons (like smoke rings). They seem to be a stable resonace in non-linear mediums that would be useful to model neural network dynamics.
2018-11-03 07:17:01 +0000 UTCI would
2018-11-03 06:58:57 +0000 UTCExactly!

2018-11-02 19:03:04 +0000 UTCOh yeah, she's great!

2018-11-02 19:02:27 +0000 UTCHmm... this might be a bit difficult to properly pull off.

2018-11-02 19:01:21 +0000 UTCIf you could strobe the cut-plane vertically at a high enough rate (and with a sufficiently fast camera) you could take 3-d movies of the structure of a smoke ring...

2018-11-01 15:11:15 +0000 UTCIs the laser actually diffracting or is it refracting through the rod? There do appear to be max and mins but the rod would need to be pretty thin to diffract the light.
2018-11-01 12:58:25 +0000 UTCJust has to be!

2018-11-01 02:09:57 +0000 UTCI wonder how vortex collision looks like in this setting, like SmarterEveryDay did.
2018-11-01 02:07:29 +0000 UTCNavier–Stokes?
2018-11-01 01:45:00 +0000 UTCAre these cross sections of toroidal vortices?
2018-11-01 01:18:45 +0000 UTCThat's pretty cool. So is the laser plane showing us a section cut of the smoke?
2018-11-01 01:17:46 +0000 UTCSomething like that :)

2018-11-01 00:34:49 +0000 UTCIs there a nonlinear dynamics video incoming?
