Early Calculus Self-Discovery
Scott Aaronson taught himself calculus at age 11 by exploring symbols in his babysitter's textbook.
He emphasized rediscovering old math as a path toward original discoveries for students.

Karp-Lipton Theorem's Implications
The Karp-Lipton theorem links advice-augmented algorithms with deep complexity collapses.
It shows if NP problems got polynomial-time algorithms with advice, the polynomial hierarchy collapses.

Understanding P vs NP
P contains problems solvable in polynomial time; NP contains problems verifiable in polynomial time.
The P vs NP question asks if problems verifiable quickly can also be solved quickly.

In this episode of the 632nm podcast, Scott Aaronson shares his early fascination with calculus at age 11 and how “rediscovering” old mathematics led him toward groundbreaking work in complexity theory. He gives a lucid explanation of P vs NP, revealing how seemingly trivial questions about verifying solutions speak to some of the deepest unsolved problems in all of computing.
Aaronson also explores the frontiers of quantum computing, from the nuances of quantum supremacy experiments to the idea of quantum money and certified randomness. He explains how amplitudes—rather than straightforward probabilities—unlock powerful interference effects, yet still face limits imposed by measurement. The conversation concludes with a look at the future of fault-tolerant quantum computers and the possibility that we’ve finally reached the ultimate horizon of computability—unless nature has even stranger surprises in store.
