The same mathematics that explains why a fridge magnet sticks to your refrigerator also explains why neural networks work when they have no right to.
Transcript, bonus content, and my Monday M.A.G.I.C. Message: briankeating.com/yt
His group did the calculation. Nobody else had.
Nigel Goldenfeld is a Professor of Physics at UC San Diego, a Fellow of the Royal Society, a Member of the National Academy of Sciences, and a former director of NASA’s Astrobiology Institute. He spent 36 years at Illinois applying condensed matter physics to problems everyone else had abandoned.
We cover:
- Why a model fitting pure noise generalizes anyway
- What Francis Crick concluded when he decided life evolved too fast to have started here
- Why the genetic code is optimal rather than arbitrary
- What horizontal gene transfer has to do with how libraries work
- Why Enceladus is the better bet and Europa is the wrong moon
- The purpose of life, stated as a thermodynamics problem
The impact you make is the ratio of what you do divided by what everybody else does. Minimize the denominator.
Nigel Goldenfeld, on this episode.
