This Is Not Yellow (by Vsauce)

but colour is an invention of our brains anyway? Is yellow a specific wavelength or is yellow what our brain says is yellow whether its red+green together, or "true" yellow.

Either way the light output by your monitor is not 580nm like your brain is telling you but rather an even mix of 650nm and 510nm.
If our eyes didn't "fudge" colors in this way we most likely wouldn't have color television (or monitors)


I didn't read his post like that, maybe he's asking for a definition of yellow because as our cones are basically wavelength filters for photons whilst our brain interprets a message of "hey i caught something of this intensity" from each of them, what is this "yellow" that we all use and think we know what it means? It will eventually come down to the resolution of the eye; each photon from each source will be coming in from a different angle into our eye, by extremely small amounts - the smallest thing we can resolve is where our brain says "ok, i think that's coming from the same place; it's not red and blue separately but yellow."

It'd be the same if you have a green and red patterned circular board and spun it really fast. Our eyes effectively have a "framerate", a point where we see something as motion. Play a game and limit to 1 fps, then increase in say 5's and before 30 you should start to feel motion rather than stuttering frames, then as you keep going you can't see stuttering anymore, it's just all motion. Our eyes have something similar, we used to do it in science. My dad was head of physics and he stuck a ROYGBIV patterned board on a black and decker drill and when it was up to speed it looked white.

So if something registers as yellow to our brains, is that not yellow? We have no direct access to our cones, we just interpret the signals. If all we had were light sensitive cells everything would be one colour and no colour at the same time.

That's what the post meant to me and it's a great point really even if it's just an excuse for sciencey discussion! If yellow is defined as a range of wavelengths of light, he's right to say it isn't yellow, but i doubt many people think of yellow in that sense. Having said all that, the video was actually interesting and informative and i enjoyed watching it, and this is probably a philosophical question for others to bother with.

PS.
Bert and Ernie, Simpsons, Smurfs, South Park, Turtles? Not sure about B&E though.

Tricks of the Sift (Howto Talk Post)

This isn't so much as a trick but more of a question as to why a certain feature goes away.
If you're a member and are logged in you can "Search" for videos but if you're not logged in the search box in the top right corner disappears. This is frustrating because sometimes I want to show people a cool video on VS but don't really want to log in due to various reasons (such as but not limited to: Not wanting an entire auditorium to know my VS name, time constants, on a public computer where I don't want to type my passwords, my name is so awesome people's heads might explode). Being able to search without logging in would be fantastic. Unfortunately, I stopped coming to VS to show people videos because of this and end up just searching Youtube. This of course limits the amount of exposure this site gets. Every now and then I show a video to more than a hundred people. That's a lot of potential future members which can lead to a better community, more exposure through word of mouth and internet talk, and even donations.
If this has been asked before and answered, I apologize and may the Flying Spaghetti Monster have mercy on my soul.
Oh and...
Yay! I popped my SiftTalk posting cherry

This is probably blocked in order to prevent attacks on the site via bots.
If you want to search a video on videosift, use google and type in:

Yeah, I know. It's just much easier to not have to back out of the page and go to Google with every new search.
Thanks for a response

This makes more sense when you can see what was actually written.

I have always wondered how to do the smaller font.... Thanks, bertie!

[edit] DANG. You still can't read what he typed. Bert, you are hysterical. And small.

from stranger blog....

"How dare these liberal movies attack the oil industry, and promote sharing? This afternoon, the Twitter hashtag #GOPMuppethearings has blown up, with Twitter users imagining what a Republican-run congressional committee would ask of the Muppets. "

1. "...no, 'C' is actually for 'communist,' sir. And I assure you that's not good enough for this committee."

2. "Mr. Gonzo, please produce your birth certificate."

3. "Mr. Bert what *is* your relationship with Mr. Ernie?"

4. "Well, the Rainbow Connection certainly sounds like a part of the radical homosexual agenda to me."

5. “Is it your contention, Mr Elmo, that your Communist Red fur is purely coincidental?"
