This Is Not Yellow - Vsauce
It’s Physics Friday, and here is a video from Michael at Vsauce that will BLOW your mind! What you are seeing right now is not yellow …
That’s right. You are not seeing yellow. Watch this video to see what you are actually seeing.
P.S. - If you look at the banner at the top of my blog you’ll see a picture of the visual spectrum of light laid overtop a picture of the Rose Nebula. That tiny sliver of yellow in the very middle, it’s not yellow …
What happens to a wet washcloth when wrung out in space? Astronaut Chris Hadfield answers this question from students with a demonstration. Without gravity to pull the water downward, surface tension effects dominate and the wrung cloth forms a tube of water around it. Surface tension and capillary action draw the fluid up and onto Hadfield’s hands as long as he holds the cloth. After he lets go, we see that the water remaining around the cloth soaks back in (again due to capillary action) and the wet, twisted washcloth simply floats without releasing water or relaxing its shape. While pretty much what I would have expected, this was a very cool result to see! (Video credit: C. Hadfield/CSA; submitted by Bobby E)

The biological and evolutionary reasons behind fight or flight, explained with funny.
Perfection.
looks for my rp group
they are not found.
RL has hijacked us all; I am now a nationally certified Emergency Medical Technician and in classes for my Intermediate, which means lots of clinical hours and shifts at Fire Departments.
I’m jet-lagged and ready for sleep, but I wanted to say that this year is definitely better than the last; no dark elves!
I hope everyone had a safe holiday.
gammapulsed replied to your photo: Somebody tell me these are a bad idea.
Hmmm. ouch, I think.That’s fair.
They’re pretty “ouch” price-wise anyway :c.
Fashion isn’t really high on my list, as you know, so I am really not the best judge.
No.
I don’t actually like Eggnog.
Stop.
I always think “Maybe this year, I’ll LOVE egg nog!”
It has never been that year.
I like the nutmeg.
Dr. Banner, it's so lovely to see you posting again! I'll bet you and The Other Guy have been busy fighting crime and doing various scientific tasks, but I'm glad you're still around from time to time. Happy holidays!
If by crime you mean frostbite in Nepal, then yes, exactly that.
Happy Holidays to you as well; thank you.
Just a word to the wise; trying to get me to ‘hulk out’ because you think he’s more festive might not be merry for all.
