I'm actually doing research at my University's optics lab with optical vortices! It's very cool to see some public showcase of these as I have really only seen dense academic papers on the subject. Great video!

The spiral light is used in microscopy to achieved superresolution (STED), going beyond the diffraction limit of the light microscope.

Did anyone else think he said “put it in a coffee machine” at 1:15 ?

This guy doesn’t even need the Infinity Stones to destroy even the whole universe.

Next episode: opening wormholes by unfolding space fractures and how to stay safe from the time devouring monsters on the other side. Me: Sure. Mhhm. Just a normal episode.

"It's the CIRCLE of LIGHT..." -- all I can hear is Elton John 3:53

I was expecting a glowing tornado

Fun fact , in Switzerland we still use overhead projectors

Awesome, can u please post a video on "Navier Stokes equations"

The thumbnail pic got me all excited...

Question: So if you will move the paper closer to the light source, the "spirals" will rotate as you move closer?

So if light has momentum. Can you do an experiment to show shining light on an object and having it move? Maybe floating a paper in your vacuum chamber and seeing if it'll move when you hit it with your laser?

Could you show us the spiraling by using a fog machine?

One day he will bend the space and time and will be the most powerful person in the omniverse

Amazing video.

U deserve the greatest appreciation for ur work.....

I can't get enough of those super hi-tech simulations.

Does sound travel in plasma and Bose-Einstein condensate?

Him: *Says momentum * Me: Okay, I'm not gonna say it. Him: *says that again a few times* Me: WHEN THE MOMENTUM, AND THE MOMENT ARE IN RHYMEEEE GIVE ME THIS MOMEEEENT

Could you also get this effect with a rotational polarising filter?

About you said at the end of the video, I not only enjoyed it, I loved it too. You've demostrated exactly how I imaginated the light could travel when I was in the school studying basic Physics and the types and physic of waves. This is one of most educative videos of Sicence I ever seen. Thank you for post it! 👍

3:54 it’s the ciiiiircle of liiiiight and we see it all

0:49 stare at the middle of the symbol and you can see a circle...

Really happy I came across this video and channel!!!

Excellent demonstration! I really wished you would have experimented with fog/smoke to see what it looks like 3D

You should never stop making videos

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

Quality is even better lately! Amazing experiment! Are other spiralizing ways doable at home?

Action Lab never disappoints.

Oh wow over head projectors. They were going out of style when I was in primary school. That's like, 15 years give or take

2:04 brings back the memories of singing in school assembly

Thank you action lab for making another fantastic video

The Action Lab is the Irish Spiraling! Triskelion

3:08 was like the fringes seen in Young's double slit experiment Have you used a double slit. Please can you explain me this

You the best!

Awesome! OAM of light is my research topic for my masters degree. We produce the vortices using fork pattern hologram on spatial light modulators....

Quantum wave particle duality and visualising the polarisation of electromagnatic radiation ... in your living room. Just amazing.

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!

Is this something that can be visualized with like a fog machine or something?

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

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.

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?

Our school still has overhead projector, and we still use 'em

not sure if i'm clickbaited or i'm just plain dumb to imagine about light vortex.

Anyone else seeing a circle in the pattern? 1:10

In Germany overhead projectors are more common than smart boards in school😂

“Next im going to turn into a pickle and this can be useful to get out of therapy sessions with your family”

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?

Is this the same as the Circular Polarized waves used for radio transmisión in FPV drone video antennas ? Since light and radio waves are electromagnetic , you should be able to make light “antennas” and radio “lenses” I think that you can make a nice video about those topics.

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.

That's really cool. So.....if you used a bigger defraction square thingy and a more powerful laser with a bigger beam, you can make a time tunnel?

Amazing! Great video

The circle of light, now that song is in my head ( the circle of life )

Awesome sir!

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

Instructions unclear. I made a black hole that ate the whole universe.

1:19 If you use SVGs, you can utilize the highest print resolution of your printer.

That is amazing!

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

overhead projector - standard polish school equipment used in 2020 in science classes.

Not to nitpick, but just for my own confusion- at 2:53, those dots aren't concentric, but co-linear, are they not?

You did not explain , why this pattern dowing this specially ?

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.

So what you’re saying is that the special beam cannon has light spiraling around the energy piccolo disperses.

Next episode will be why does afternoon not have a name.I mean why is it called after the noon please help me understand this

Physics: light travels in a straight line. The action lab : No.

Question: have you tried using this same process of printing and transferring onto projector slides to create double slit apparati? Buying double slits where the openings are small enough that the interference pattern isn't overwhelmed by the diffraction pattern can be really expensive. If this works it would be a really nice DIY option that I would definitely use in my classes

We’re you able to bend the light using a flux capacitor?

Hello is spired light the same as circularly polarized light?

I saw a video on youtube a long time ago (about 2007) and the students were doing this in a hallway and I think one of them said they figured it out and they were doing testing on it to improve privacy during communication. In this video the had the laser going through a fog and you could see the light bend around itself in a double helix. 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

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.

Please reply! Was water boiling at 100°C and freezing at 0°C a coincidence or freezing point of water was said 0°C and boiling point as 100°C?

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." ;-)

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

Super nice 👍👍👍

How u r able to get all these idea its really amazing

Are both of those spirals in same direction?

You can blow smoke on a laser beam and see the straight line but what would the beam look like if you were to blow smoke/fog/whatever across this?

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?

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

1:15 i honestly thought he said coffee machine i was so excited to see what the heck he was gonna do with it

Get the pattern where? Link doesn't work. What's wrong with internet, availability of information isn't maintained.Like a library full of books missing pages.

love your content btw

What happens when you pass this light through a polariser

Can I do this project for my science exhibition.

I’d never noticed how much he speaks with his hands

Does this phenomenon have a correlation to the black hole pictures taken by telescopes?

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)?

Okay, Increase and decrease the distance between the source and target. I'm not convinced! You still haven't proven this to me. If I'm wrong, someone please explain. By the way you opened up, it sounds like you saying light has mass

This man clearly lives in year 9999.

amazing content

Nice shirt! ;)

Im just chillin then DO YOU WANT TO LEARN HOW TO SPEEEN LIIIIGGHHHTT

I was honestly hoping for a fog machine or something to show the light in the air

How does this pattern on the paper makes light to spin in a spiral shape?

Watch this man start controlling a black hole in his garage

so a single point can have multiple synchronized photons, some spiral or do those move slower, so by combining spiral and flat you can create bright spots , in space. inspiring.Or is that a hologram.

How is it possible for light to have angular/linear momentum without having a mass

OMG I hate it when KZfaqrs use video thumbnails of things that aren't even in their videos!

could you do this with sound?
