Episode notes

European physicists are going underground, building a subterranean gravitational wave observatory. This would be only ten kilometers long, but the being underground would help to shield out vibrations. And they're using various other things to try and maximize their ability to detect very low frequency gravitational waves. Well, hopefully in the future than we'll get even more national wave detections.

A computer that can participate in live debates against human opponents.

00:43 AI Debater

After thousands of years of human practise, it’s still not clear what makes a good argument. Despite this, researchers have been developing computer programs that can find and process arguments. And this week, researchers at IBM are publishing details of an artificial intelligence that is capable of debating with humans.
