After a friend of mine got a tattoo with a representation of the cosecant function, it got me thinking about how there's another sense in which this function is a tattoo on math, so to speak.
They've found the winning formula to get the ladies in the mood...but at what cost? Thanks a lot, Mumford & Sons - Derick Watts & The Sunday Blues realise that with great power comes great responsibility!

Dot products are a nice geometric tool for understanding projection. But now that we know about linear transformations, we can get a deeper feel for what's going on with the dot product, and the connection between its numerical computation and its geometric interpretation.

There's a slight mistake at 13:33, where the angle should be arctan(1/2) = 26.565 degrees, not 30 degrees. Arg! If anyone asks, I was just...er...rounding to the nearest 10's.
For those looking to read more into group theory, I'm a fan of Keith Conrads expository papers: http://www.math.uconn.edu/~kconrad/blurbs/

The same guys who brought you the "Anaconda Fart Remix" are back with a stab at Maroon 5's attempt to pull the wool over our eyes. It was pretty darn clear that their "Sugar" music video was staged, but here is how it probably WOULD have turned out had it not been.
Guest starring Chloƫ Kiley & Lloyd Carney

The fundamental vector concepts of span, linear combinations, linear dependence, and bases all center on one surprisingly important operation: Scaling several vectors and adding them together.
