Godel's shadow: what mathematics says computation can never do

Roger Penrose builds on Godel and Turing to argue that understanding goes beyond algorithms, Edward Frenkel sees paradox and limits at the heart of mathematics, and Stephen Wolfram describes computational irreducibility. Each identifies a different hard limit on what calculation can predict or prove.

Let the physics do the work: the idea behind graceful legged robots

Russ Tedrake, Robert Playter and Marc Raibert all trace agile robots back to the same principle from the MIT Leg Lab era, which is to work with a body's natural dynamics instead of fighting them. It matters because it explains why balance and movement, not raw computing power, were the first breakthroughs in legged machines.
