Richard Feynman Mirror

[msjessypp]

some sweet info here

[sk8shred]

I need his brain for my physics and mathematics tests/exams (A) Such a wonderful man

WHAT KEEPS A TRAIN ON THE TRACK???!!!

[cnestudy1]

what we see in the mirror is a defraction of light. what the hell is he talking about" squashing heads to look like us"??? hell is this guy

[Azyashi]

@cnestudy1 defraction? That's not a word. Perhaps you mean diffraction?

But even if you do mean diffraction, you're still wrong. Diffraction is what happens to waves as they pass around an obstacle. Mirrors don't diffract, they reflect.

And to answer your final question, this guy is Richard Feynman, and he's right and you were wrong! =)

[the42Q]

It really should have been called a fbrev - as mirror is not an accurate description. fb standing for front back and rev for reverser.

[Th0111]

That's exactly the question I was thinking about a few weeks ago standing in the bath and brushing my teeth:)

[GalacticMuppet]

Basically, Feynman is saying reflection is different to rotation, but when we first see a mirror we think the image has been rotated though the image it is in fact reflected.

[WarPhalange]

"We don't think of the idea that the person has been pushed and squashed backwards-forwards, because that's not what ordinarily happens to people." Pfft, this guy's never been to Detroit, obviously.

[mililaniguy]

Anyone who has ever taken organic chemistry should know this.

[MajorGeneralPanic]

Can you explicate this?

[mililaniguy]

Look up stereoisomers. That should help explain.

[gamewarrior2216]

My answer was light relfection but yeah that answer sounds good... I guess.

[spacepirate725]

Wow, I feel smart because I know what keeps a train on the tracks. Thanks, Physics class.

[TheHaohmaru]

I hope when I get old I can sit in a wing-back chair and sound like that.

[NightshadeMortis]

If someone asked me that question, I would think they were a retard and I would away....clearly I'd be at the wrong college. That is not a trick question...at all.

[designflaw01]

I don't doubt that Feynman was a genius but the average person can understand that mirrors invert right and left. Hell even pigs and cats understand this concept.

[bspoka]

@designflaw01 you obviously did not finish the video... It is obvious that the mirror inverts left and right, however what feynman was trying to explain that even though we perceive the left/ right axis to flip it is the one that is pointing into the mirror that actually gets inverted.

[NightshadeMortis]

Omg, nothing is inverted. It's simply a reflection. There's no explaining to be done. The mirror reflects visible light near perfectly. It seems like a "flipped" or "inverted" image because the mirror has the same viewpoint that another person would have if looking at you. The mirror allows you to see your self from the front as others see you. There is no inverting or flipping done. This video was pointless.

[agenteighty]

Nice work NightshadeMortis - you have a level of scientific knowledge, combined with an articulate yet clear voice that speaks to me in ways I never thought possible. Your deep and strongly scientific explanation of how a mirror works is like poetry to me. You really are a genius. I wish I could be like you. You are my idol.

[NightshadeMortis]

...*locks doors*

[Manwithcam]

@NightshadeMortis Holy shit you're stupid.

[wowsa0]

@NightshadeMortis 'The mirror allows you to see your self from the front as others see you.'

When others look at me from the front my heart is not on the right.

[NightshadeMortis]

@wowsa0 Well...mine is.

[Psued0Name]

If you listened, it was a typical problem used in MIT fraternities. And most folks, the answer is only obvious once it is explained.

And the part of genius is to boil a complex problem down to its essentials so that the answer seem easy.

@cunfyoosed

path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the super fluidity of super cooled liquid helium, as well as work in particle physics (he proposed the Parton model). For his contributions to the development of quantum electrodynamics, Feynman was a joint recipient of the Nobel Prize in Physics in 1965, together with Julian Schwinger and Sin-Itiro Tomonaga.

what have you accomplished? other than getting a nuke in mw2

[NSResponder]

I thought he was going to explain how the silvering returns the photons in the direction from which they came.

[omidsarmad]

lol same

[Gansmiller]

A mirror is not a retro reflector... so it doesn't return them in the direction that they came in. It is simply reflecting them, so angle of incidence equals angle of reflection.

[ludmac7]

lol, i thought of the same question while checking my car's mirrors a few months ago XD

[dhannyboy86]

Degrasse is awesome too. he really grabs your attention.

[dhannyboy86]

only 142 views? sad

[rageatm4life]

@dhannyboy86 29,202 now

[dhannyboy86]

@rageatm4life Sweet! all these Feynman video views are increasing! I take it as a good sign

[alien8ted]

Brilliant! There are mere geniuses, then there is Feynman!

[greenleaf81]

Yes! Feynman is brilliant and equally entertaining unlike many other boring dull scientists.

Carl Sagan is another of my favt. Scientist.
