the space race may be the funniest point in history period and i'll stand by that. the US is like "yes whoever gets into space first will prove once and for all that our economic model is superior and that we are, in general, the superior country of superior and smarter people." then the soviets just went and did it and the US freaked out and needed to cover their ass so were like "WE MEAN THE MOON, WE MEAN THE FIRST TO LAND ON THE MOON."

Listen to the sound of wikipedia

This is a way to listen to changes to wikipedia. You are literally listening to knowledge being added to the world.

Pluck sounds are an addition, strings are subtractions, and the pitch says how how big the edit is. My heart shudders at this I love it so much.

I’m a huge fan of how rhodochrosite can either look like beautiful pink flowers, like pointy red crystals, like little Barbie-pink orbs, or like meat

An example of crown flashes, also called jumping sun dogs. They’re streamers of light above storm clouds that appear to dance and flash, sometimes quite rapidly, looking like search lights or huge light sabers.

They’re almost certainly caused by long ice crystals above the cloud that align themselves with the cloud’s electric field. If you see them from the right angle, they bend (or refract) the sunlight toward you, causing the glow. 

When lightning erupts from the cloud to the ground (or inside the cloud) the electric field changes radically, realigning the ice crystals. When this happens they suddenly bend sunlight in a different direction, causing the glow to shift. (Source)
