Playtime Comments : [Veritasium] How To Make Colour With Holes

Ru*****:

1:30. First male Victoria's Secret model

Yo***:

0:13, well according to all your street videos, I'm highly skeptical about this claim

se*****:

3:45 That's how they coat sunglasses to filter out specific frequencies

be****************:

0:50 Phet! I use that when I teach my GCSE class about radio waves.

No********:

0:13 "most people know that [light] is a form of electromagnetic radiation..."

uh, no. most people do not know that.

Si*************:

epic laugh at the end... ehuh huh huh huh huh.. 5:28 :D

Ju************:

2:30 Look at the fairy! The fairies are real! lol

LE******:

2:33 lmao he has wings :p

Sh*************:

At 4:23 I realized that the shaved guy is also Derek. This is the first time I'm watching an old video on this channel.

Au*********:

0:58 Finally someone explains how photons are created! In school and most videos they just say "when an electron gets excited they emit a photon." And that barely explains what's going on

ve*********:

Wow, as a graphic designer I really want a printer that could do this

Il******:

See Richard Feynman's lecture series on QED here on youtube to understand the physics behind this. He explains it in the first of the four lectures.

Se******:

One of the coolest videos I've seen in a while, especially the visualization of how soap bubbles cancel out certain wavelengths of light.

Da**********:

do you intentionally have those wings in the back ground to make you look like a fairy princess ?

Er******:

I wish you were my science teacher

pa*********:

The butterfly proves Intelligent Design. No amount of random anything will result in such a wonderful structure.

De*********:

Oooooh god, that is genius, I FINALLI got it! So when u explain how the green is removed, since u've got 250 nm between the first and the second wall, multiplied by two it gives 500 nm which is the exact distance that green light travels for a full wavelength, and so it meets the green light that is the same "state" (troth or... what was it called again xD). I got it at like... The fifth view of this video.

Ar*********:

I wish the US would do something like this. However we (US people) seem to be stuck in the past.

2J***********:

THIS IS THE GREATEST VIDEO I'VE SEEN IN YEARS

Gu*****:

Derek, you're hella handsome!

St***:

Your a pretty fairy

bl********:

I have a 100 dollar bill that has the transparent tape on it.

Br****:

Australia has many technologies exceeding that of other countries, we have great healthcare, low crime rates, better security oh and we invented wi fi which a lot of people would have used to watch this video

In******************:

So what you're saying is that Australia has been ahead of the game for and we're technologically superior to the rest of the world without question? Yeah I'd agree with that

Jo******:

"I cannot comment on that" = "Yes, absolutely. That's 100% correct"

Ha***********:

The only thing that could make this channel more like VSauce is if the guy popped up into the frame at the beginning of every paragraph.

Ri*********:

So to remove the green wvelength to form magenta, the thickness of the soap film would have to cause the the crests of the 1st reflection to align with the troughs of the 2nd reflection (and vice versa)....causing destructive interference, the removal of the green wavelength, at that spot on the soap film. Is this correct?

Ja*********:

So funny because they joked about talks with the australian government about inclduing this on notes and now new australian $5 note that rolled out last week actually ended up with this technology

sa**********:

but where does the energy go from the light that gets destroyed, by interfering with itself?

So**********:

Dear Veritasium. One day when I was lying on my back with a straw hat covering my face I found that if I focused my eyes correctly upon the holes in the straw I could see the surface of my eye. When I blinked I could see a line in the fluid upon my eye like a windscreen wiper and particles of dust drifting across the surface. Could you explain this? Does the small aperture cause the light reflected from the inside of my eye to come into sharp focus like a pupil creating a reverse projection.

Be**:

Is the same process used to create that shiny 3d mark on a credit card?

sp*****************:

the thumbnail looks as if he was some strange kind of fairy

sh******:

Why do they named it Blue morpho butterfly if it has a color of gold and white?

Th************:

What if you accidentally punch out that film on your bank notes?

Ad*********:

Derek is looking awesome after clean shave.

To********:

I wonder. If you had a surface of nano-mechanical plungers, each 100nm wide and able to actuate pependicular to the surface 100nm, could you create a system for a display? THere is some precedent for this, DLP projectors have tiny mirrors on a chip that can move around. Now those mirrors are (according to wikipedia) 5.4µm, which is a way bigger, but they also needed thier pixels to pivot in two directions, if we have it acting as a solinoid, 100nm might be a viable option. Though what strikes me as the biggest difficulty would be the distances between the holes really. I'll have to give this some further thought.

Da********:

Sad that we see fiat currency as so valuable.

Ca***********:

Great vid. also great to meet you the other day!
Subscribed :)

su************:

I just wanted to tell you, that I really enjoy your videos. Your personality is very attractive, and your accent is marvelous. However, the best reason that I enjoy your videos is that you cover your topics very well. You explain why, and how the physics of science works, but on a level that doesn't necessarily need a college degree to understand what is happening.

Thank you for being a great teacher. I'm from Montgomery, AL. in America, I started watching YouTube about 5 years ago, after obtaining my first laptop. After learning how to navigate around on the internet, I found YouTube. Your channel was the very first one I discovered, and I liked. I subscribe to it immediately. I enjoy science and learning about how the universe works because of the laws of physics. Please keep them coming. Take care, John Trusty.
