In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also,...

The other day I got bored and noticed this weird thing happened when I held my finger up to my eye, so I had to science it and figure it out! Let me know if you try these light-bending experiments too, especially that last one that I...

Two authors battle it out on SciShow to see who knows the most about animal clothes and mysterious circumstances.

A curious pattern in polar plots with prime numbers, together with discussion of Dirichlet's theorem

Some birds fly in V shapes because it has many benefits, but other birds fly in clumps instead. Why would they do that?
