This is super cool and yes it is very interesting to use spiralized light and the modes of OAM (orbital angular momentum) of light from entangled photon sources as a variable for entanglement steering and with setups that can use OAM and polarization entanglement simultaneously one can do a very interesting experiment called entanglement distillation which is one of my research goals using non-linear optics entanglement sources (BBO and KTP). actually your setup I think may very well work at the wavelengths I'm covering! 810nm, I'd love to try your print out haha it would make a much more affordable setup than using components from Thorlabs!

Wow epic symbolism the snake and the stick ! There is a lot more going on here and I am now hooked to this channel. So can light or radio waves travel around corners ? That being it has sideways momentum.

Hello is spired light the same as circularly polarized light?

Everytime i see your new video clicks the video and repeat with you - hey guys todayyyy i m going to

“So if you look down the center of this, you can actually see the center of it”

Can you introduce a medium which will allow us to see the spiral of light along its path/ is there a way to film/ capture a "snapshot" of the light in space at its transmission frequency to "freeze" the spiral for viewing?

The natural first (Occam’s) assumption to explain how or why a particle like a photon (or electron, etc) might behave as an uncertain location particle while also like a polarizable axial or helical wave ''packet'', given that everything in the universe from electrons to solar systems are in orbit with something else pulling them into polarizable axial or helical apparent waves depending on the orientation of their orbits as they travel thru space, and given that we know we’re in a sea of undetectable dark matter but don’t know where it’s disbursed, is that they’re in orbit with an undetectable dark matter particle pulling them into polarizable axial or helical apparent waves as they travel where the speed of their orbit determines the wavelength and the diameter is the amplitude which would explain the double slit, uncertainty, etc. No?

When you said, "overhead projector" the first thing that came to mind was Beavis &Butt-head destroying one in the school parking lot. "Yeah yeah kick it.Break it, break it break it!!! Yeah I hate those things." ;-)

Nice shirt! ;)

is the light spin affected by Coriolis effect of gravity IE spin right or left (not necessarily by earth but larger wells in space)?

Please explain how electromagnetic equipment can give energy freely by perpetual motion, using only magnets and batteries, the equipment once given motion continues to move without any external force and it also produces current that does work like lighting a bulb

This "spiral light", more commonly called circularly polarized light, is the principle behind most 3D glasses, with the lenses filtering opposite rotations. If they were using regular polarized light filters(which some still do), the glasses would work best only when viewing straight, so tilting your head would greatly impact your vision.

Vortex beams are not circularly polarised light. Vortex beams are rotating wavefronts (carry orbital angular momentum) whereas circularly polarised light are local rotations of the electric field around the propagation axis (carry spin orbital momentum). Circularly polarised light when projected on a surface normal to its propagation axis will not give a donut intensity profile.

I do not see a link in description to the pattern you have. ???

Is there a way to do this experiment and have the light go through a mist to see it?

And what if you let water particles/drops pass/fall down between the laser system you created and the wall with the light from the laser hitting it? Will you be able to see the spiral of light?

This guy is saving a generation from the void of Bill Nye and Myth Busters Academics keep getting more and more contrived in confusing jargon and elaborate theories But school is getting further and further from common sense, practical, hands on, inexpensive, demonstrations, explanations etc Wood shop, machine shop, pottery, arts crafts, photography, gardening, debate, drama, apprenticeships, entry level jobs, So many things have been deemed Kindergartners should have toys that have levers, pulleys, pneumatics, etc

If you want more information on a subject that is really similar look into linear polarizers, circular polarizers, and quarter/half wave-plates. This will give you an more indepth idea of how photons (particles of light) travel in air and how the "fields" (which represents an approximation of the exchange of photons from one object to another) of the photons can change due to light hitting the wave plates or polarizers.

So extrapolating this principle...is that basically the conception of the universe emerging as a hologram (a "line" of light projected can appear as a circle, and so on and so on)?

Hi Thaks for this video I have tried to understand the vortex of light only since the advent of the James Webb Telescope, in order to understand the coronagraph, which enables weak-luminous stars and planets to be shown after blocking the strong light of their stars. But now I'm starting to think that the vortex of light is an electromagnetic wave with rotating polarization?? Is this what really happens?

Could you please test and show gravitation lensing, By using a large flat bath with a drain in the middle to create a vortex representing a black hole or large body. And shine a not so dangerous laser pointer threw and around it. Demonstrating how space is more like a fluid and how gravity influences it. Under water camera would be interesting to capture the laser passing behind, and maybe a white board to see how the light tracks across it via passing behind the vortex. I guess someone is making waterproof laser pointers... Or put it in waterproof vessel.

It was way cooler than what I saw here, but I think this is how the did it I remember them saying something about that Y shape. EDIT: After that I could never find the video ever again
