AlphaZero perspective on value in chess

AlphaZero is an AI which has been trained to play several sorts of games.

By training not from existing games but by self-play, has provided a new analysis of games. The style of play is different from more traditional chess engines due to the more complex analysis performed, which provides a different perspective on the value of different moves.

Some videos from IM Anna Rudolf on AlphaZero syle of chess play. There is a playlist on her youtube site here:

SpaceX discover wonders of steel rocket skins

When SpaceX started fabricating the top portion of a space ship from steel, and building it exposed to the elements rather than in a hanger, contracting a company that normally builds water towers, people speculated that it was just a mock-up because their “Hopper” is a development platform, not intended to do into space. However as more details have been revealed it seems like this is a first step for SpaceX in using stainless steel for a reusable rocket. Here they use an Austenitic Stainless steel, a material suitable for use at cryogenic temperatures and with a greater temperature capability than aluminium. A particular advantage may be the lower thermal conductivity, since it is intended to have heat tiles attached to the outside,

Rock Hard Carbide

Hard Rock cafe in Chicago is in the Carbide and Carbon Building, maybe a more appropriate name would be the “Rock Hard Cafe”? Carbides are fairly hard materials, and carbon, in the form of diamond is the hardest.

McNamara and the story of Forrest gump

The Project 100,000 “new standards program” commenced by Robert McNamara in 1966 drafted 100,000 men formally rejected as they fell in the lower 30 percentile in the Armed Forces Qualification Test, failing tests for mental and education standards. The story of Forrest Gump was to be shared by around 100,000 men per year, colloquially labelled as McNamara’s morons, men who would be an asset to the army as they could be trained using modern methods such as video tape to bring them up to speed.

Although the mental standards where lowered to increase the numbers drafted without having to draft college educated men and the national reserve, the standards were still slightly higher than the entrance standards during the Korean war.

Hamilton Gregory talks about his book McNamara’s folly discussing the programme:
