Today’s Google Doodle (visit google.com to see it, or if you miss today, you can find it in their archive) celebrates Russian mathematician Olga Ladyzhenskaya. In recognition of her 97th birthday, the Doodle includes the Navier-Stokes equations, of which Ladyzhenskaya provided the first rigorous proofs of convergence using a finite-difference method.

- Maths learning organisation (and Carnival of Mathematics stalwarts) Ganit Charcha are running a competition for schools in India, challenging them to ‘Doodle for π‘ – students should take inspiration from a mathematical concept, and create a doodle/image to submit. The competition invites creativity and imagination, and runs until 12th March.
- If you’re not in India, you can still use π as inspiration for artworks – Think Maths speaker and Aperiodical Math-off contestant Zoe Griffiths has put together a set of ideas for how to use π to create beautiful pictures, to decorate your home, school or office.

It’s that time of year again – 3.14 (March 14th), a.k.a π day, is just around the corner, and if you want to do something fun on the day, now’s the time to plan it. One nice way to celebrate this brilliant infinite string of digits is by creating π-inspired art, and we’ve spotted a couple of relevant links if that’s your jam.

# Making Tricurves

Tim Lexen has written a series of posts on the topic of Tricurves: Bending the Law of Sines, Combining Tricurves and Phantom Tiling. In this latest post, Tim has been working with our own Katie Steckles to turn Tricurves into real objects to play with. When you discover an interesting mathematical shape or object, there’s a…

# Nine months of HLF blogging

I’ve now been writing fortnightly blog posts for the Heidelberg Laureate Forum’s Spektrum blog for over nine months. Small trumpet noises!
