I’ve done another maths video! If you missed it earlier this week, here’s a nice mathematical card trick I learned recently on a trip to Finland. Enjoy!
My wife’s school recently sent round a form with questions about “a day in the life” of people working in STEM careers, to show to their year 6 children. My job involves the M in STEM, so I agreed to have a go at describing my day.
I quite enjoyed describing about what I do, so I’ve decided to reproduce my answers here. Enjoy!
As if there wasn’t enough maths/pizza news lately, the story has hit the red-tops recently that UK supermarkets are scamming consumers by offering them oval-shaped pizzas – marketed in the high-end/’Extra Special’ ranges, with more expensive (sounding) ingredients like mozzarella di bufala, roquito peppers and merguez sausage, and a distinctive pair of artisanally different radii. These pizzas apparently cost more per gram, because their elliptical shape means they’re actually smaller than a circle with the same diameter. Cue plenty of ‘costing you dough’ and ‘cheesed off’ puns.
While we’re not massively bothered by the pricing, the articles do raise, and then completely fail to address, an interesting point: an oval pizza is harder to cut into equally sized pieces! Luckily, maths is here to save the day. I found a nice method and made a video explaining how it works:
The next issue of the Carnival of Mathematics, rounding up blog posts from the month of February, and compiled by Robin, is now online at Theorem of the Day.
The Carnival rounds up maths blog posts from all over the internet, including some from our own Aperiodical. See our Carnival of Mathematics page for more information.
As part of our series of ‘Follow Friday’ posts in which we suggest mathematical Twitter accounts you might like to follow, here’s a special International Women’s Day edition with some of our favourite mathematical women and related accounts. If you’d like the conversation in your feed to be less dominated by the Sausage Theorem, maybe consider adding a few to your lists. Put your own suggestions in the comments too!
Mega-late to the party, I’ve now arrived back from a week lecturing in Indonesia and have found time to go and see the incredibly well-received and widely talked-about NASA women maths film, Hidden Figures. I’ve heard an incredible number of wildly positive responses to the film, from as long ago as January, and have been looking forward to it greatly.
The film is a painstaking and at times brutally realistic depiction of the struggles faced by African-Americans, and by women, during the era of the early space missions.
Today is International Women’s Day, so we’ve taken a moment to think about the woman mathematicians in our lives.
