Aperiodvent, Day 16: Relatively Prime Christmas Special

Remember this time last year, when we had a chat with Samuel Hansen for their amazing Relatively Prime podcast? We discussed our collective hobby of getting angry at stupid formulae in the news, and how it sometimes crosses over with the festive season. Listen again below.

Registration for 2019 Alan Turing Cryptography Competition and MathsBombe is open

The Alan Turing Cryptography Competition, now in its 7th year, is an online competition run by the University of Manchester School of Mathematics, for school students up to year 11 or equivalent. Cryptographic puzzles are released every couple of weeks and teams of up to four compete to solve the puzzles, with prizes for the fastest and other randomly selected correct entries. Registrations are open now, and the competition starts on 28th January 2019.

For sixth form pupils, there is also MathsBombe – an online competition, with two mathematical puzzles released every fortnight. The puzzles are not directly related to the A-Level syllabus but will require students to use their problem-solving skills.

Aperiodvent, Day 12: Fractal Christmas Trees

If you’re looking for a fun hands-on project that’s mathematical and Christmassy, look no further than Think Maths‘ classic Fractal Christmas trees – building a Sierpinski tetrahedron tree, Menger Sponge base and Koch Snowflake star.

Aperiodvent, Day 11: MathsJam Shout

Today is the regular monthly MathsJam date for people to meet in pubs and do maths all over the world (some are meeting next week instead – check to find your nearest). Their internal puzzle sharing sheet is snowflake themed this month, and is shared online so you can join in from home.

Aperiodvent, Day 10: Dimensional Analysis and Turkeys

Photo of Jim ProppBefore he entered Aperiodical’s Big Internet Math-Off, contestant Jim Propp wrote this lovely blog post about dimensional analysis back in February, using it to predict how well Michael Jordan would be able to play basketball on the moon and how long it would take to roast a large bird. Make use of it when you’re planning Christmas dinner!
