Mile of Pi - Numberphile
This video by Numberphile is uncharacteristically light on math but is still pretty cool to watch - they printed out a million digits of pi (which ended up being just over a mile of pi) and unravelled it on the landing strip of an airport in Denmark!

As we've written about before, mitochondria generate the energy required by our cells through respiration that involves using an "electrochemical gradient" as an energy store (a bit like pumping water up into a reservoir for energy storage to then harness it flowing down the gradient of a hill to turn a turbine), and produces free oxygen radicals as by-products (a bit like sparks when the engine is running hot). The fundamental importance of this machinery which not only delivers energy, but is

What's in the list you keep (internally or physically) of things we still traditionally teach in our math courses that just feel "wrong" in 2014? Memorizing formulas is probably one of my least favorite things, and I know I have that in common with my students, so wherever and whenever possible! I like to teach them the concept on a pattern level or with strategies that have more than one
