How Do 3D Films Work? | Earth Science

[@jamiecauson2828]

There is something about James May's videos that makes you want to make you watch them all, in a row , non stop.

[@sohaibakram92]

I really Love James May presentation style!

[@kuzmychmaksym3843]

I freaking love his accent. I've never been watching TopGear in original, I was always been watching it in translation and now I see how much I've lost.

[@foxchaim5370]

i dont mean to be so off topic but does anyone know a tool to get back into an instagram account..? I somehow forgot the account password. I appreciate any tips you can give me

@@foxchaim5370 wait did you made this youtube channel only to comment this💀💀💀

[@UpsideDownMon]

it would be awesome to hear about how all computer parts work. maybe do a couple of episodes on that

[@Dragonion2010]

2:35 "because of something called persistence of vision" Yay POV-Ray :)

[@Ambidextroid]

Why is he standing in front of a PS2 menu screen?

[@omelettesquirrel4485]

Fun?

[@DaRealMikeyBruh.5o17]

just notice that

[@therunawaykid6523]

Good question or he is in the sky with the buildings from mirrors edge below him 😏😏

HeadSqueeze has some of the best animations on KZbin and TV in fact :)

[@AuricomOne]

That crazy gif. Saw the link and when I saw Captain Slow - knew it was a treat.

[@equinox9]

There's a thin layer in front called a parallax barrier filled with tiny gaps. The gaps mean certain parts of the screen are hidden from one angle but can be seen from another. So because your eyes are at different angles to the screen, each eye sees a different picture.

[@mountnstream]

True, I only watch these and the ones with Matt Parker, but that's because he's also on Numberphile.

[@liamtaylor3576]

hard drives work by storing their data using microscopic liner magnets. This is why they can be wiped with magnets. The arm in the hard drive positions the magnets to be read later by the computer. how they stay still while it's spinning I have no idea.

[@alihamud322]

Can you explain more?

[@ManuelGarridoPena]

And now, this is my favorite person in youtube,

[@ManWithBeard1990]

It uses a kind of ribbed plastic lens (not a fresnel lens. That's something else entirely) to make your eyes see a different pixel depending on where they are. So each pixel, or at least, what your eye thinks is a pixel, is actually four pixels. You just see a different one depending on what angle you're looking at it from. You know those 3D flippo's from the 90's, right? It works like that. Peel off the ribbed plastic on one, and you'll see what I mean.

[@DynamixWarePro]

This is the reason I subscribed! I know some won't know them, but how do the older removable storage devices work like floppy disks, Magnetic tape storage devices, Bernoulli Box and Zip/Jaz Drives work?

[@harismichail2]

James you are THE teacher. wouldn't trust to explain that question to anyone else. Can you please, Please explain torque to me?

[@MrOwned94]

Torque- A twisting force that tends to cause rotation. 369 foot-pounds means that if you had a wrench that was 1 foot long, and applied a force of 369 pounds directly perpendicular to that wrench, you would get 369 foot-pounds of torque.

[@SamnissArandeen]

I know the answer, it's an invention of Erno Rubik. There are seven algorithms in the "Beginner's Method". What I was asking, though, was how those algorithms were found in the first place. (And just so I could watch James explain it, because goddammit, he's awesome.)

[@MrOwned94]

Its great to just read some of the questions posed and responses in the comments.

[@Urf93]

Love James :!

[@0609mruehle]

When you close one eye you don't actually see in 3D, but your brain can use other cues to create a "3D-ish" perception of the world. For example: things that are out of focus behind what you are looking at, or things moving across your field of view at different rates when you move your head, and converging of lines (perspective) all help your brain to create a sense of depth. Most 2D cartoons use these effects to suggest depth as well. But 'Real' 3D (stereoscopic vision) requires both eyes.

[@ManWithBeard1990]

There's also a type of glasses that filters out different wavelengths of each color, only a few nanometres apart. So there are six wavelenghts being displayed. Two reds, two greens and two blues. And the glasses can filter that out appropriately. Those glasses are cheaper than the ones with shutters you can buy for your home, and do not go erratic and leak part of the other image when you tilt your head a bit like the polarized ones do.

[@jx592]

By 1:36 my tiny brain has deduced that if i try to poke a nearby cat with both eyes open, left hand. Then alternate between the two eyes, my right eye combined with left hand equals further depth perception. It actually took me a little further to make contact with said cat. Science 🐱 👈👀

[@IJico256]

This is because when the brain only has one image, it tries to infer depth the best it can. It also uses information from recent images, so the effect might work better if instead of closing one eye, you close your eyes, turn your head, then open one eye.

[@Pile_of_carbon]

This channel is brilliant!

[@procartoon]

I really enjoy these videos! Good job, sir.

[@bezoticallyyours83]

This was a pretty cool video and a good explanation.

[@da12ius]

Yea James, that shirt is messin with me! Class.

[@Metalmanz3]

Always love some new video with the May explaining shit.

[@martanigraphics]

What a great shirt! Where do you get them from James?

[@larrybooth1771]

Gordon Gordon Wyatt from Bones. Loved your part as a psychologist. Forgive me if I've mistaken you for that guy.

[@524sbth]

Loved this one! Very smart!

[@524sbth]

Favorite James shirt!

[@bobsobol]

Q: How do Hard Disks work? A: Quite differently from one another. The earliest Winchester drives where literally metal platters placed in a stack, with information recorded magnetically, but like a vinyl record. Modern magnetic Hard Disks work similarly, but with more information on smaller discs in a little box, but...! SSD Hard Disks don't have a disc at all, and are simply Static RAM chips, much more like digital camera SD cards or USB memory. Now discuss SCSI, IDE, ATA, TTL, MFM and SATA.

[@MrOwned94]

If you could give a reference for me to check on then I would but if not then I'm afraid I've not heard of it. Any article will do, and always check sources on things like that.

[@mattfox14]

2:27 spot James May

[@FreakinPeanut]

James May is a legend....seriously

[@chriswww]

The 3d movies generally use polarized lenses not shutters. The shutters cost a lot of money whereas the polarizing type is cheap. I'm not sure of the reason why you get a headache but it could be the distance between your eyes, the difference between the two images and the distance between you and the cinema screen don't match up properly so your brain has to work overtime to compensate for these differences when it creates the image.

[@thief9001]

I hope when you answer how hard drives work, you also touch on how Solid-State ones do! That would be cool.

[@unamaxify]

you forgot about the autostereoscopic technology where tiny lenses on the screen or paper direct the light into the corresponding eye (either the to right one or the left one) this was used on a popular gaming handheld as well as on "3D wobble pictures" that usually were included with sugary American cereal

[@forevercomputing]

A hard drive is different from a hard disk. The hard disk is the entire unit. The hard drive is a drive on the hard disk. But this must be set up or formatted. This would be done with partitioning, all disks intended for use must contain one partition and hence, one drive. Setting up more would be multiple drives on one disk.

[@nahomgirma5501]

James May is the best

[@hsmeyer93]

I've been wondering about this for a long time: How do nuclear explosions (and in particular, clouds produced by them) get their distinctive shapes?

[@MrOwned94]

what I mean is the only thing we have really discovered that does this naturally would be large stars and even then due to the timescales we have little knowledge of any other occurrences or ways to form them.

[@reck101101]

It is just nice to hear James May talk. What a gentleman- bloke ....ish

[@godnyx117]

3D gives me some nostalgia!

[@Cellsd]

Yes, I get that but what of the theories on particle accelerators that may create black holes on earth?? I remember reading something on a massive particle accelerator that they refrained from using, as it may create a black hole

[@Cellsd]

Damn, that is incredible Thanks

[@MasterAccordionKing]

Haha! Loved the ending!

[@wmarema93]

I love this man.

[@MrKDilkington0]

This is like an internet version of James May's Things You Need to Know About... TV series.

[@inspirality]

These videos with James are so much better than that dreadful animation thing.

[@TheKapperify]

What about the "primary" eye? Like if you close one of your eyes, and the thing you see still looks like when both eyes were opened?

[@memus3852]

It's like an itch: Once you give in, you won't stop until it hurts. (Ergo Head Squeeze... interesting...)

[@p4x.frontier]

Hmm, that "Persistence of vision"... THAT'S why when I look away then back at a clock the seconds hand stays still longer! Now I know. :D

[@danzigrulze5211]

I concur I would always get frustrated with the damn thing and just take all the stickers off and put them back.

[@LordTwaddle]

I just realised that instead of Clarkson interrupting, I'm listening to may droning, wow...

[@Barachat]

They usually are stars, but in theory any extremely dense object could be a black hole. Vsauce did something on black holes, explaining that if earth was condensed to the size of a peanut while retaining the same weight, its gravitational pull would be like a black hole's.

[@matisstar]

how do James May's Q&A work? no i mean for real how you guys make this whole thing?

[@KyeMclachlan]

Sensors in the road. Next time you are at an intersection have a look on the road. There are lines cut out into the road with cables in them.

[@ericrevollo]

There's a funny side effect of blue red glasses, look at 3d images with them for a while, then take them off and look at something white close one eye and you will see white becomes colored either blue or red.

[@kooksies5712]

microwaves are on the ionising side of the electromagnetic spectrum (purple and above), this means they have this ability to ionise electrons. THAT means they can cause an electron to literally fly off the metal causing an electric spark. i believe its called the photoelectric effect. if you google it im sure you'll discover microwave photons are not the only ones able to do this.

[@AGH0STBUSTER5]

how does a digital camera know when it is in focus?

[@kooksies5712]

it's the same as diffusion except its to do with fluids (primarily water) across a partially permeable barrier (or membrane)

[@Cellsd]

I just did, and damn its some next level stuff

[@RiffRaffMakes]

James I'd very much love it if you could explain how electricity works, my mother can't get her head around it but she loves you to bits so she might actually listen to the point of understand. (You are welcome to take her out on a date, however if she kidnaps you I can't be held responsible...)

[@Cellsd]

James May, I need you to thoroughly explain black holes. What would happen if one was, let's say, created or came to exist on earth. What would it do? And what would happen to someone if he/she falls through it?? How would we perceive it??7

[@SamnissArandeen]

James, how do Rubik's Cubes work and how were the algorithms derived to solve them?

[@thelonewolfesoldier]

I like the james may ones headsqueeze isn't all that cool but james may is

[@moralrefai]

I want to know how the television work and when the first podcast was

[@logoncal21]

that is a tricky one stig has so many facts about him

[@SynphamyMusic]

So if you watch a film that's been "post 3D'd" Is that what results in 'ghosting'? When you sort of get a bit of double vision with certain objects or people in the odd scene here and there?... I have to admit though, i agree with the cardboard thing, but Titanic was incredible in 3D. I think that'd be because James Cameron is just a genius anyway.

[@Bobbleoff]

James hard drives are like a jukebox full of records and but instead of using a needle to read they use a small magnet to pick up magneticaly chaeged particles which represent 0 and 1 as in binary instead of groves

[@nino2910]

Crazy the brain work so fast

[@frederickhf241]

I'd imagine it would be more or less the same as having two eyes. Although one advantage I see would be the ability to having slightly higher accuracy in depth perception.

[@Sachi_Ray]

imagine if we had more than 2 eyes......closing one and viewing through others would be extreme fun!

[@EluciaDeLuteIma]

0:53 ok you got me

[@ryanlewis1704]

If you Pause it at 1:56. James May make a hilarious Zoolander Impression :D hahaha

[@applepieindesky]

That's a good one

[@rroge5]

this one pick this one!

[@AtticusHimself]

No such thing as a SSD Hard Disk. It's just: 'SSD' or 'Solid State Drive'. No hard or disk in the name. HDD is 'Hard Disk Drive' and refers to the previous storage technology. Anyway other than that good explanation, I agree mostly.

[@LIGERZER0X1]

Imagine, EVERY video that James May appears in are 3D...

[@LadyTink]

3:14 I like how you pronounce "bothered" You actually say it correctly, as apposed to how some british folk say "bovered" :)

[@maxvandenhoven2320]

yes

[@1234567895182]

well search it up. its pretty interesting actually. i researched it and a genius mustv made the rubk's cube lol. it is very interesting! i also searched how to solve a rubik's cube and found that algorithms are used to solve them! the people who hold world records just use shortened versons and combinations of algorithms to solve it. it does take an amazing amount of skill to solve the cube in 6 seconds. Just by analyzing the cube they know what algorithms to use. now thats amazing!

[@harrycarr5224]

I dont think you will make a video but why do planes ook like they are flying slowly? Thanks

[@1234567895182]

so why is it that when i close one of my eyes i can still see in 3d. i may not beable to percive depth that well but i still see in 3d

[@jt2197]

They actually ARE 3 dimensional but we don't see it that way?

[@Near310]

James, how does The Stig work?

[@TheKandyan]

Nice

Never could see the 3D in the old method. The new method fools my brain for a few minutes, then I see both images, get a really bad headache and look for bin into which to vomit.

[@MrDawggy313]

Magic

[@1234567895182]

lol i guess it would be interesting to hear it coming from James. but i guess its people who are seriosuly good at math and geometry or trial and error. computer programers have to make algorithms all the time and sometimes it requires intense thinking and lots of trial and error

[@RiffRaffMakes]

*understanding...

[@bobsobol]

I agree with your interpretation of "correct use of language", but that's not what people are calling them, or where they get put. Like IDE or SATA... I thought SATA *was* IDE, Serial IDE, to be precise. Or the "turbo" button computers used to have... Do they have any idea what a turbo is? How would that even work!? lol The "drive" part actually refers (I believe) to the motor, so it's just a "Solid State Device". Pen Drive? Thumb Drive? No... :( lol
