Check out this adorably fantastic thankstank art that was sent in by SciShow viewers Tori and Mallory! It features the names of the fishy inhabitants of our office tank, as well as a corndog-lured anglerfish, Mount McDoobly-Doo the rock, and Papa the tree. Thanks, you two!
Why do dogs eat grass? A look at your pup’s wild relatives may give you a sense of what dogs’ diets are really like.
SciShow explains the genetics — and physics — behind why blue eyes are blue, and what the future may be for the trait. Spoiler alert: Blue eyes aren’t really blue! SciShow explains!
What wiped out the dinosaurs? Most of us were taught it was a killer asteroid — which is true. But it turns out there was more than one disaster movie playing at the cineplex that was Earth 66 million years ago.
Humans judge each other within 33 milliseconds of seeing each other! We learn better if we think we have to teach someone else, and video games are good for us!
Did you know that we’ve got 100 freshly-signed copies of SciShow: The Apocalypse Collection on DVD?! These DVDs feature 8 SciShow episodes, lots of outtakes, 25 minutes’ worth of interviews with the SciShow crew, and a big ol’ signature by the one and only Hank Green.
In this episode of SciShow Space News, Hank details the work of the European Space Agency’s Rosetta spacecraft. He also explains the new discoveries of Jupiter’s moon Io.
First, there’s gravity everywhere. We’ve got a whole episode on it. But we also have this unit of force called the g-force, sometimes abbreviated as G (though this isn’t a technical SI unit.) One G is the amount of force we all experience because of the Earth’s gravity all the time. Two Gs would be double that…we can experience this much force if we’re accelerating away from earth or on a planet two-times more massive than earth (but the same size.) Likewise, if we are in constant freefall (as astronauts are when they orbit the earth) they will experience no Gs at all. We would call that “Zero G” which is not, oddly enough, the same thing as “zero gravity.” Gravity is a force…not amount of force, and just because you are under the influence of gravity (as everything in the universe is (as far as we know)) does not mean you are feeling “G forces.”
