Nathan Myhrvold likes to challenge conventional wisdom. When the founder and CEO of Intellectual Ventures (and former Chief Technology Officer at Microsoft) isn’t running one of the world’s leading invention businesses, he’s busy doing norm-defying research on topics like dinosaur bone density, asteroid sizing, and the proper way to knead dough. Kara and Nathan talk about everything from AI, politics, nuclear power, and global warming to “splash shots” — photographs of colliding wine glasses.
