Theoretical physics and applied maths. I occasionally see people at the back of seminars with their laptop open, pugging away at their current puzzle with Mathematica.

I've used it to test and prototype calculations and algorithms.

The Stackexchange page for Mathematica is pretty amazing, and quite a good community.

The main sections of the talk without note are:

- Bert and Natural Language processing, - Tesla Autopilot Hardware v2+: NN at scale, - AdaNet: AutoML with Ensembles, - AutoAugmentation, - Training Deep Networks with Synthetic data, - Segmentation Annotation with Polygon-RNN++, - DAWNBench: Training fast and cheap, - Big GAN: state of the art in image sythesis, - Video to Video Synthesis, - Semantic segmentation, - AlphaZero and openAI Five, - Deep learning frameworks

A medical doctor friend of mine pointed out that thinking slow was fine, except in an emergency or indeed any time--limited situation where the rate of response needs to be above some threshold. Think: baraster responding to opponent, a and e doctor, board-room negotiation etc.

"Chaos" by James Gleick is about the same age as Hawking's book. The story of discovery there gives a great idea of the adventure in science.

I would be interested to know if there is some good software which copies some of the mechanics of over head projector presentations.

Seems there are some people producing lovingly hand written presentations using tablets

The old ohp slides can be beautiful: I highly recommend digging out Roger Penrose talks on YouTube

This type of calculation is used on a very regular basis in molecular dynamics simulation. The wrap-around space is implemented using periodic boundary conditions. Calculating the distance between points is most often done using what is called the minimum image convention. In one dimension for a "box" of length L the minimum image distance between particles i and j: xij = xj - xi can be calculated through xij <- xij - L*nint(xij/L). This avoids any if statements.

In "Surly you're joking my Feynman" there is the story of RF talking to the painter who teaches him to mix paints, and the colours you need to get make yellow. Turns out you should talk to the person who's been mixing paints all their working life.

Isn't there a similar story after the challenger accident where he talks to the maintenance people on the ground?
