I haven’t been able to do yoga this week due to a mild lower arm injury, so I have invested myself in self-motivated learning.

I’m using MIT’s open courseware, and the courses are AWESOME.

Fun fact for the day: The basic unit of mass, the kilogram, is the only basic quantity measurement that is still defined by an actual physical artifact. It’s a lovely alloy cylinder in France holding down the fort as the official copy and basis of ‘what is’ 1kg! Thanks International Bureau of Weights and Measures for keeping the SI system constant!

(Note: the committe is discussing revisions that would base the kg unit on constants of nature, so the unit will stand the test of time, but until then…)
