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 6 жыл бұрын

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.)

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 6 жыл бұрын

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)

Not trying to sell you anything, I just think it's one of the most amazing pieces of tech i've ever seen!

@sisyphyus 3 жыл бұрын

@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.
