I can watch these allday

[@sergiocortesgodoy]

Amazing! It blew my mind seeing the different lattices

[@wayneyue1662]

amazing!

[@GerardHammond]

This is one of my favourite quantum videos. Any followups?

[@jareknowak8712]

Great job!!

[@x1magalhaes]

Amazing

[@christianresources1912]

This would make Einstein so happy.

[@seditt5146]

Doubtful, its about to disprove everything he worked towards.

[@81giorikas]

@@seditt5146 On the contrary.

[@qzamboni]

@@seditt5146 No, Einstein was working on a theory of "ghost fields" - pilot wave theory inspired by de Broglie - before he died. This would validate everything he worked towards.

How wonderful to be able to save such a treasure

[@ninapersson4109]

Wow!

[@andrewferg8737]

The wells are not fences. They correspond to frequencies arising from interactions with the quantum vacuum and other particle /waves on the quantum scale, or electromagnetic field interactions on a macro scale, or gravitational interactions on an astronomical scale.

or gravitational interactions on a quantum scale, that would explain why light changes direction and slows down relative to a vacuum in glass, a sharp increase in gravity causing a strong pull toward the surface of the glass, and the time dilation caused by said difference in gravity causing the light to continue moving at C, but in a different relative frame compared to vacuum

@@Information_Seeker
Refraction of light is an electromagnetic phenomenon. Scale is important when discussing the different forces, although they do display apparent similarities (hence my comment about the wells in the experiment). The contribution of gravity at the microscopic level is insignificant in relation to the electromagnetic fields in the refraction of light, or other electromagnetic waves.

Очень интересно!

Makes me want hundreds of them.

[@alonsovm2880]

what this has to do with ferromagentism, why extrapolate like that.

[@qzamboni]

Ferromagnetism is an ordering of spins. Spin is intrinsic angular momentum. These droplets have intrinsic angular momentum. The whole point of the video is that the intrinsic angular momentum of these droplets is aligning just like spins do in (anti-)ferromagnetism.

[@rotgertesla]

So you are holding the dropplets inside a circular underwater fence? What happen if you slowly remove those fence once the lattice is created?

[@billyte1265]

No. There is no fence. These particles are only interacting with the wave they create on the oil bath. They lock into lattices based on their relative phase of bounce.

[@tgfoftg2946]

@@billyte1265 Could the fence be considered as some kind of dynamic pressure reflected from the well? There is no information in the video about shape of well or wells under latices.

[@cea6770]

@@billyte1265 Although there is no fence it seems there is a sudden depth difference at the boundaries thus implementing a circular potential well. Check 0:27
