Mathical books for kids award winners announced

By Katie Steckles. Posted April 20, 2015



US organisations the Mathematical Sciences Research Institute (MSRI) and the Children’s Book Council (CBC) have founded a youth book prize, called Mathical: Books for Kids from Tots to Teens. The prizes, awarded for the first time this year, recognise the most inspiring maths-related fiction and nonfiction books aimed at young people. This year, they’ve awarded a set of prizes for books released in 2014, as well as honouring books published been 2009 and 2014, plus two ‘hall of fame’ winners from the further past.

C: $K_A m; \\ K_B d.$

A: $\neg K_A d; \\ m \vDash \neg K_B m.$

B: $d \not\vDash K_B m; \\ (K_A(\neg K_B m)) \vDash K_B (m,d).$

A: $m \wedge K_B(m,d) \vDash K_A (m,d).$

Albert, Bernard and Cheryl have had a busy week. They’re the stars of #thatlogicproblem, a question from a Singapore maths test that was posted to Facebook by a TV presenter and quickly sent the internet deduction-crazy.

First of all: no, it’s not meant to be answered by an average Singaporean student. It’s a hard question from a schools Olympiad test.

Here’s a round-up of some mathematical news from last month.

Bread & Kisses

By Christian Lawson-Perfect. Posted March 24, 2015



Bread & Kisses is a short film by Katherine Fitzgerald about a mathematician who discovers love – I know, I know, you’ve heard this one before – but it also contains a mathematician who moves to the Alps to get more skiing in, so it’s the most realistic film about mathematicians ever. It also features the emotion of love in a star turn as an epsilon term.

Although it contains the line, “you forgot the most important ingredient: love”, so don’t get your hopes too high.
