I've written up a 7 slide intro to Go maths for those with a mathematical inclination (high school - uni - beyond) and some Go knowledge. It covers connections to different parts of maths, sorts of problems in Go, with a case study of board evaluation, inspired by Bill Spight.

My word of the year is 度 du4.

It normally means degree (temperature), or measure.

In Go, it normally means "reasonable extent". A strategy or move is said to have "度" if it has good balance between trying to take the opponent's territory and making territory and development of its own. It is normally in contrast to playing too deep or too aggressively.

Give me triangles strong enough and I can measure the universe.

When Venus transits, we can align our clocks to one event. By measuring the angle to flat Earth at two places far apart on Earth, we can compute the distance to Venus and the Sun.
