This week we talk about academia. How does it work? The career track is long and has many twists and turns. There are also a lot of jobs many people never think about. And what is this elusive colloquium we speak of?

• Do parachutes really work? How do we know without double blind, randomized, placebo controlled, crossover trials? (Thanks for Nick H. for this fun paper!)

• Smith, Gordon CS, and Jill P. Pell. “Parachute use to prevent death and major trauma related to gravitational challenge: systematic review of randomised controlled trials.” British Medical Journal 327.7429 (2003): 1459.
