Why These Two Planets SHOULD Be the Same
You'd think that two planets with similar stats, orbits, and parent stars would grow up to be pretty similar, but these twins have atmospheres that beg to differ.

Z-Scores and Percentiles - Crash Course Statistics
Today we’re going to talk about how we compare things that aren’t exactly the same - or aren’t measured in the same way. For example, if you wanted to know if a 1200 on the SAT is better than the 25 on the ACT. For this, we need to...

Jonathan Drori: What we think we know
Starting with four basic questions (that you may be surprised to find you can't answer), Jonathan Drori looks at the gaps in our knowledge -- and specifically, what we don't about science that we might think we do.

Mathematical Thinking - Crash Course Statistics
Today we’re going to talk about numeracy - that is understanding numbers. From really really big numbers to really small numbers, it's difficult to comprehend information at this scale, but these are often the types of numbers we see...

Making a Realistic Simulation of the Sun
We’ve created simulations to recreate the difference in time it takes for the Sun’s equator and poles to complete rotations, and the way we’ve solved is a bit surprising. And it looks like the Milky Way may not be great at mixing metals,...
