Sound and fire = complicated!

The Rubens Tube is a really complicated demo that seems simple. Once you start thinking about it you realise that sound antinodes are points of oscillating pressure, so the flames shouldn’t be stable peaks – they should be going up and down at the frequency of the wave!

And if you change the gas pressure a lot the nodes and antinodes reverse position! Wish I’d thought these points through before Derek asked me to film this!

 

Using antimatter to find weirdo supernovae

Fiona Panther is searching out galaxy for antimatter – no it’s not science fiction, she’s after anti – electrons, called positrons. It’ll help her to study supernovae – exploding stars.

Fi is a PhD student at ANU Research School of Astronomy and Astrophysics, Mt Stromlo.
