How do 3D glasses work?!

Have you ever thought about what kind of optics those cheap plastic glasses use to make movies 3D? It has to do with circular polarization of electromagnetic waves (otherwise known as light). The physics is actually pretty cool.

How can you do everything so interesting and explain it so simply? I have understand, you have been a teacher? Why oh why we didn´t have teachers like you in my school-days!!? I´m from Finland and our school-system is praised to be so advanced and student-friendly. Bull... When I was at school I was about to get weary every day. We spend hours and hours learning something very simple and then practice again. Now my son goes school and really nothing has changed. There are levels, but as I fill out the initial form I told that he can read and write. What happens? He goes to group that is learning to read and mathematics were level 1+1=3. It took 2 months before they find that out and were really sorry that he was signed up in a wrong group. What does that tell about our educated school-system? I really really wish there was teachers like you. Man, You Rule! Hmm.. could you make a video about holograms, how they really work and what happens in quantum level? Thank You for this super-interesting channel and please, keep up the good work! (sorry about this long story).

Hey, Nick. I was wondering if you could explain something that I genuinly can't seem to properly grasp; Hawking Radiation indicates that black holes eventually 'evaporates' and vanishes, due to all the mass being gone. How does Hawking radiation escape the event horizon when even electromagnetic waves cannot? I know it's due to virtual particles, but I seriously can't seem to grasp that. Thank you; I adore your explanations to fascinating content!

[@ScienceAsylum]

The virtual particles are not escaping from inside the horizon. Virtual particles are created in pairs and sometimes only one of them is inside the horizon. The other can be outside and is free to escape. (Of course, that's the grossly over-simplified explanation. I happen to know PBS Space Time is releasing a video on this soon. It might be worth checking out.)

Thank you for your explanation. I was curious how it works 👍

I have "accidentally" forgotten to return my Real 3D glasses on many occasions. This is mainly because I "accidentally" figured the glasses were part of the price to see the movie, and I don't trust them to not "accidentally" give me some glasses that were used and possibly has someone else' lice or other contaminant on them.

[@OvidiuHretcanu]

if you forget to keep them where I live, you will have to buy other pair (by "accident") on your next movie. You always keep them ;) Besides, it better to recycle, isn't it?

[@aymendzcultureentertainmen5530]

[@snapshotsnapshot3622]

In France, we buy the glasses at the entrance of the theatre for 1€ and we keep them at the end, so there is no point in giving them back

[@Noah_B127]

I did not forget I took like 10 and made some super cool thing with two shades of the glasses on top of each other and it makes light colorful

[@omarnoor767]

The theater I go to gave us a pair that had a normal right eyepiece. But the left was strange, if you look through it you see only blue shades and if you tilt it and make vortical you only see red shades. Can you explain that to me?

[@haangpa]

Hi, I am looking for a way in which an invisible projection can be viewed only by a 3D glass sort. That too each glass would view negative and positive version of the projection. Is invisible projection possible? Is negative and positive viewing possible with 3D glass?

[@QuadiePoo]

I never give back my 3D glasses. Shoot a 3D movie is expensive. I take what I can 😆

[@culwin]

I didn't know we were required to give back the glasses. I just walked out with a couple pairs, and nobody said anything. But then I give the rest back because I don't want any more. Do theaters actually care if they get them back?

[@tisebi14]

culwin no it's accounted for in the price of your movie ticket but if you give em back they'll just give them to someone else so it's a way to make more money essentialy

[@ScienceAsylum]

There's usually a big cardboard box in the hallway outside the theater. They don't "police" it or anything though.

[@culwin]

Please don't report me

[@hckr47]

culwin too late😉

[@ooloncolluphid7904]

+culwin So that was YOU!!! Seriously, though, those glasses are pretty expensive in the grand scheme of things (say, if a theater loses a dozen or so a show). They can range from $10 to $30 a pair, depending on what projection system they use. You probably just lucked up by getting lazy ushers. SHAME ON YOU!!! I've still got two pair....

[@StanleyKowalski.]

if 50K subscribers each gave30 cents a month ( yes 30 cents a month) , he would devote most of his time to these beautiful videos. you cant be that cheap

[@lidarman2]

For those enjoying this video and 3d movies, go to the bathroom at the theater with the glasses (or at home with a pair you took with you since you did pay for them) and look in the mirror wearing them. Then cover/close one eye.

[@crossbreed7625]

[@LarryBinFL]

Nick, you've asked "Do you have a question that's driving you crazy?". I do. We take for granted the notion of "static energy", e.g., if I raise a weight upwards and put it on a shelf, it takes energy to do so, and that energy can be recovered later by letting it fall. My question is: What kind of energy IS that, and where IS it? If E=MC^2, does the object have more mass?

[@ScienceAsylum]

Lifting the weight upward gives it what we call "potential energy." Energy isn't like a substance that exists. It doesn't have a "where." It just _exists_ or it doesn't. To answer your last question though, yes, the object would have more mass. (the extra height doesn't add much mass though, so you wouldn't be able to measure the difference)

[@sisyphyus]

How about 30 Spectral Lensing glasses? Trust me, and look them up. They come with a coloring book but try them at an art gallery!!! You can use them anywhere (just not for long, they can give you headaches and/or make you ill). P.S. Not trying to sell you anything, I just think it's one of the most amazing pieces of tech i've ever seen!

[@sisyphyus]

@Rose Jenna Prieto Arias Since my original comment, I actually found and purchased a 10 pack of the very glasses I commented about without having to buy another kids coloring book. They go by a few different terms but rainbow depth or spectrum stretch should point you better to what I'm talking about. I like these glasses best because they let in everything, and don't require the image to be altered or designed specifically for them, they work with any image (technically, but best results are with "true" colors like actual Red, Orange, Yellow, Green and blue. Pastel wavelengths are "fuzzy" because of the extra colors coming in due to the white needed for the effect of pastels). Seriously, I took a pair of these glasses to a local art gallery and the pieces with strong "true" colors looked AMAZING in 3D when I tried them on and looked at them. Anachrome, if I understand the technology correctly, requires the image to be created a specific way in order to work properly.

[@Beethoven1111]

Hey, what are your thoughts on this, I've been wondering a lot about this lately when I watched your relativity series. . . is Math relative? Maybe you can do a video on that. . . take throwing a tennis ball for example. The standard quadratic representation of the shape the ball would travel wouldn't work in a situation with drastically different gravitational fields. But I'm not a mathematician, so, there could be a mathematical work around to this I'm missing. But I suspect math is relative just because of the fact the equations and theories we use to describe things and how they work are very relative to our earthly environment.

[@ScienceAsylum]

The physics (scientific math) we use to describe things like tennis balls also works on things like planets orbiting stars and stars orbiting the centers of galaxies. It's not based on our earthly environment. If it was, we'd be failing at our job as physicists.

[@Abhi-no3sf]

I forgot to give the 3d glasses. But when i came back i didn't see anyone to give it. So i thought i will keep it. Can this 3d glasses can use for any video from mobile or TV for a 3d effect?

No, they can't be used anywhere. There are many different methods for creating 3D images. The method used in theaters is just one of them.
