A deep-dive into electric vehicle technology and a comparison to the old clunky topic of gasoline cars. Gas engines are 18% efficient. Electric motors are 85%-95% efficient. It is a no brainer to use electric right? It is a bit more complicated than that. A demonstration of a tiny electric motorcycle will introduce you to the world of electric vehicles. Then we will talk in detail about: battery technology, battery management, motor types, motor controllers, efficiency, rapid charging, and why the world isn't electric yet.

Do you find that your mind - and your pencil - wander during math classes? Are your shoelaces nearly impossible to unsnarl? So are ours! Come hang out while we play with string, talk about knots, and doodle the infinite. We'll talk about knots that can't be undone (but can be turned into other knots), drawing knots on paper, map coloring, fractals and space filling curves.
