Food for Martian thought, proton role-playing in a video game and more

By Tushna Commissariat

With space agencies across the world planning manned missions to Mars in the coming decades, pondering what one would eat while on Mars seems like a sensible thing to do. SpaceX engineer Andrew Rader helps us out with this difficult question in the video above, sharing gems like “chickens can’t swallow in space.” In the video, titled “Cooking on Mars” Rader cooks and eats a seemingly unappetizing option – bugs and insects – and makes it clear that is the fare future astronauts will be partaking in.

Winning rock-paper-scissors, meeting a future Nobel laureate, hot new batteries and more

When I was a PhD student, there was a group of retired professors that shared a tiny office in the physics department. It was whispered that one of them was extremely wealthy thanks to a successful commercial spin-out and we marvelled at the fact that he came in to work every day rather than enjoying the fruits of his labours. However, it wasn’t the wealthy professor who was destined for international fame. In 1994 his officemate Bertram Brockhouse shared the Nobel Prize for Physics, and Brockhouse’s quiet life changed dramatically. Indeed, he got his own office!

I was reminded of this little group when I read ZapperZ’s blog entry about his encounter with Ray Davis before Davis bagged the 2002 Nobel for his work on neutrinos. Sitting next to Davis on a two-hour flight, ZapperZ had an inkling that he was beside an interesting character after their brief chat about physics. But it wasn’t until the Nobel was announced several years later that he realized the opportunity he had missed.

Cruise-ship physics, the many ways to tie a tie, shaken-up carbon dating and more

By Tushna Commissariat

If you like piña coladas and quantum mechanics, then we hope you are currently on the two-week “Bright Horizons 19” Southeast Asia cruise, as on board is physicist and writer Sean Carroll. He will be giving multiple lectures over the next 15 days on everything from the Higgs boson to dark matter and other fundamentals of quantum mechanics. Also floating along with Carroll are other lecturers who will cover topics from natural history to genetics to military strategy. If, like us, you are stuck at home, you can take a look at Carroll’s slides on his blog, maybe have a cocktail while you are at it.
