Still laughing at Brian May offhandedly writing the greatest understatement in the history of academia in his astrophysics doctoral dissertation:

Ah, yes - “various pressures.” Like being one of the greatest guitarists ever and playing/writing/singing for the most legendary rock band of all time.

Those various pressures.

Lynn Conway passed away this weekend. She was an electrical engineer whose professional work was instrumental in enabling virtually all modern semiconductor devices. She was fired from IBM, and lost her family for transitioning, and later came out and became an outspoken transgender activist.

Rest Easy, Lynn, the world is less for your absence.
