Happy New Year, Vsauce! Michael here. And in honor of 2013

To begin, where to spend all that cash you picked up over the holidays?

Now, plenty of website sell cool stuff. United Nuclear sells

Aerogel, radioactive isotopes, jet engine schematic

and even marbles doped with uranium. Maths Gear sells these cool non transitive

of the land effect. Even though it appears to contain

a bunch of different colors - oranges and yellows and greens,

the entire image is actually made out of nothing

but red. Seriously. I've linked the image down in the descriptions, so you can grab

your favorite image editor. The yellows are actually

light reds or pinks. And the green is just dull grey

color constancy. Your visual system, your eyes and brain

calculate the average illumination conditions of a scene

and then subtract those conditions, so that colors remain relatively constant.

This is why a blue object looks blue, whether you're viewing it

under the midday Sun or a dark red sunset or fluorescent light or

It's a very brilliant system, but it can fool

us. Special images, like this one, appear to be illuminated with a lot of red

so your brain actually subtracts the red and makes assumptions.

There are plenty of other examples of the land effect and other ways our visual

that depiction of raindrops. Raindrops are not shaped like

teardrops. Surface tension means that  small drops are spherical,

but when they combine the air and get bigger, the pressure of the air below

flatten, which means that raindrops are shaped less like

and there are plenty of resources discussing how many raindrops fall

but throughout all of history? Let's go to mathforum.org for this one.

quite roughly but amusingly, that given the percentage of earth

usually covered in land and the amount of rain that

typically falls on earth and the volume of a raindrop,

the total number of raindrops that have fallen on land,

ever since earth began, is about 16 times

But you know what earth doesn't have a lot of? Nice big, old chunks of Moon rock.

Material from the Moon is incredibly rare.

We can only get pieces of the Moon in two ways. By

visiting it or by finding chunks of the Moon that were blown off

a long time ago and eventually fell to Earth.

the searchable Calvin and Hobbes. I shared this on @tweetsauce a few weeks ago.

Type in a word and you can find every single Calvin and Hobbes comic strip

that used that word. Words or phrases that help you remember something are

mnemonics. For instance, if you wanna remember the exact

Four circles with corners cut out of them. We perceive

an actual square resting on top of circles, even though no square

is there. Now interestingly, if you take this shape

and put it on top of text, the letters within the

fake square appear bigger than the rest of the letters.

This is because our brain assumes the letters are closer to us

than the rest of the text. After all, the letters are on top of a square
