In this video I calculate a value for g, the acceleration due to gravity, by treating my hair as a simple pendulum. Uncertainty analysis was done following the method outlined here: https://www.youtube.com/watch?v=HVyjjcRmIwQ

Thanks (and happy birthday) to my brother Jack for his appearance in this video.

At 3:00 the uncertainty in the period is 50ms. And the unit for L should be m.

I make videos about physics, math, astronomy and scientific beauty with a new episode every wednesday and sunday.
