Teo tells us about his work in artificial intelligence, his travels around the world, and how inspiration sometimes strikes in the pub.

Clouds make the weather, yet their detail isn't taken into account in weather forecasts. Artificial intelligence might be able to help.

Predicting the weather is hard. With more data and computing power becoming available, artificial intelligence can help.

How does your phone know what the weather's going to be like?

How a little insect can cause chaos.

Consider these two divergent series.

Sp = +1 + 1 + 1 ....

Sn = -1 - 1 - 1 ...

If added together, all terms cancel and Sp + Sn = 0.

However, if one allows the illegitimate preliminary step of "

shifting" either series left or right,one can arbitrarily produce a result of any integer value you want to get. The operation of shifting (or of defining a "series" that starts with a finite number of zeros) creates a finite series that becomes the result. The amount of shifting determines the number you get, because the rest of the infinite series will still cancel.BTW, notice also that Sp + Sn = S1 from the video. So, if one rules out illegitimate cheating steps that artificially create a finite series (e.g. shifting or bracketing), the result is that

Sp + Sn = S1 = 0.
