Talks from the TEDxCaltech event are gradually coming online. You’ll definitely want to check out Scott Aaronson’s contribution, which was a clear highlight. (The biggest highlight was the closing jam session featuring keyboard wizard Lyle Mays and Tuvan throat-singer Ondar. You heard right.)
But just to show it’s not all about me, you should also see this talk by awesome undergrad Jordan Theriot. I would have been a puddle of nervous jelly in this venue at that age.
