In August I did a course in Sustainable Stand Up with the marvellous Belina Raffy. Here's the result. Inappropriate thoughts and bad fart jokes. but we all gotta start somewhere... 🙂 https://youtu.be/fMiEGudKXoE
Professor Rod Boswell from ANU shows off a nanosatellite and explains how they are revolutionising the space industry. https://youtu.be/jfPAGWG34cc
There's been a lot of news about the electrician who got busted hiding his phone/PDA in a foil Twisties packet to prevent his company from tracking him... so he could go play golf. So I decided to give it a whirl, in some chocolate wrapper. And then try out the microwave. but that wasn't so … Continue reading Faraday Cage: using a foil Twisties packet to hide from your boss
From Physics in the Pub 2016, a great set from Leon Twardy about sound waves, how microphones work, and how an acoustic guitar steals energy from the future. https://youtu.be/35uZ34Ri168
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 … Continue reading Sound and fire = complicated!
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. https://youtu.be/qDCMuhTXo_Y Fi is a PhD student at ANU Research School of Astronomy and Astrophysics, Mt Stromlo. Filmed at Physics in the Pub, 2016, Smith's Alternative. … Continue reading Using antimatter to find weirdo supernovae
We know PhD students like to do things on the cheap... well Ryan Ridden-Harper is doing high altitude astronomy - like the Hubble space telescope - but with no expensive satellite, just a weather balloon. He hopes it will give nice cheap insights into dark energy! https://youtu.be/EUCSk5-7Rbw
https://youtu.be/c-r8LKosap4 A surprise find of blue wine in the washing up opened up a world of chemistry in the kitchen. Turns out red wine and purple cabbage show amazing colours as you change their acidity. They are acid-base indicators, due to chemicals called anthocyanins.
I had the honour to interview David Reitze, one of the leaders in gravitational wave physics, when he visited Canberra earlier this year. Bit surprised he wasn't one of the Nobel laureates... but anyway, ahead of the exciting announcement tomorrow, (what have they found this time?!), here's the interview. https://youtu.be/AYcH-qtKxuo And for those who … Continue reading Gravitational Waves – behind the scenes
Some lovely footage of superconductors weaving their magical levitation spell https://youtu.be/Uk0BivSXiAI One from the archives from Eurofusion.
