Samuel Hansen is a busy man. As well as finishing off Relatively Prime, he’s continually making up new ideas for podcasts. His latest effort is ACMEScience NEWS NOW, a series of video interviews with the people behind scientific and mathematical research stories in the news.
We didn’t post about episode 1, with Paul Hines talking about crowdsourcing, due to it coming out in that weird bit of the Summer where all three of us fell asleep for a few weeks. But last night Sam posted episode 2 — an interview with Sally Dodson-Robinson about modelling planet formation — so here it is:
You may remember Math52, a Kickstarter project from Mathalicious which reached its goal in June. This promised, “every week for a year we’ll create a short video exploring a unique application of math in everyday life”. Now the Mathalicious video series has launched with two videos, both less than two minutes in length, available via YouTube.
The first video, Tip Jar, explores tipping in restaurants.
When we go out to eat at a restaurant, it’s customary to tip as a percent of the total bill. But is this fair? And what are some other ways we might pay waiters & waitresses?
The videos are snappy and nicely produced. The Mathalicious website offers free lesson plans and materials to support the video in the classroom.
A few days ago, my friend David asked me if I could help him with a card trick. I said I could, hence this post. I managed to pin David down in front of my camera long enough for him to demonstrate the trick; a full explanation follows this video:
Having discovered this wonderful design for a paper Enigma machine, which uses a standard size crisp tube and does a pretty good job of encoding things like an Enigma machine, I decided it was worth trying it out. What better opportunity to use something which can encode secret messages than to send messages between two monthly Maths Jam events via the medium of Twitter? The public sending of the messages would be incomprehensible to anyone not willing to get their hands dirty with a crisp tube and scissors. Unless they’ve got an actual Enigma machine.
Anyone who hasn’t yet spotted the YouTube channel Numberphile (call yourself a maths fan?) would do well to check out its amazing selection of videos, all loosely themed around numbers – not all of which are integers, either – but now edging on giving up on that pretence and just continuing to post videos about interesting bits of maths.
As a mathematician (and not just any kind of mathematician – a PURE mathematician), I heard of the “Dance Your PhD” contest and immediately burst out laughing. As much as there is some nice pure mathematical dancing out there (see, for instance, this series of videos of different numerical sorting algorithms interpreted through dance), the idea that someone’s mathematical PhD research could be conveyed via bodily gyration was both fantastical and hilarious.
