Welcome to STEMology – Show Notes
Season 1, Episode 30
Musical tree rings, historical bang, anti-aircraft ravens, and supernova deja vu
In today’s episode of STEMology…
Sophie & Dave will talk about dating musical instruments using tree rings, how the medieval soldiers make gunpowder, drone-hating Australian ravens and how researchers have been sighting a supernova while predicting when we’ll see it again…
They want to understand what it is about these old instruments that makes them so special basically. And in order to do that, they want to look at the woods because that’s one of the main things that the instrument is made of.
And basically in a nutshell, what happened was a bunch of historians and chemists went and got some like medieval recipes for gunpowder, and then they made the gunpowder and then they exploded it.
Can you imagine being scalded by coffee dropped from an attacked drone? … It will be disaster for all concerned? Cause I mean the raven itself is not going to be liable, even if it’s responsible.

We’re talking about cosmic events over the scale of 10 billion years. We’re making predictions about when something’s going to happen that far away and that long ago, within two years.
