The Teddy Rocks Maths 2023 Showcase is finally here!! After the mammoth task of reading nearly 300 incredible entries (thanks to all of you for your amazing efforts) it's time to share them with the world. Find the first 12 at tomrocksmaths.com (link on profile). [Image shows voting systems around the world where red indicates a "first past the post" system, and blue "proportional representation.] #tomrocksmaths #teddyrocksmaths #showcase

Huge thanks to the year 12 students @carmel_college who not only came to see my talk on ocean pollution, but did so during lunchtime! Amazing commitment to both maths and the environment :) #tomrocksmaths #carmelcollege #oceanpollution

If you've been following the Oxford Linear Algebra series (based on the course I teach my students) then don't forget to sign-up for a 30-day free trial of @proprepeducation to see how much it can help you to improve your STEM skills. Image shows the blackboard from my latest video on the Direct Sum of Vector Spaces which you can watch at tomrocksmaths.com (link on profile) #tomrocksmaths #proprep #directsum

Tattoo #52 - Sigrún, Queen of the Valkyries. Defeating her in God of War was probably the most fun - and most frustrated - I’ve ever been playing a video game. An epic challenge to end an incredible game. Left hand side is fresh and right hand side is healed (each took 4 hours). #tomrocksmaths #sigrun #valkyrie

NEW VIDEO: Parabolic Mirrors @numberphile_official. One of my favourite geometry calculations which shows how a parabola focuses all incoming horizontal beams into a single point, making it ideal for satellites, torches, and listening devices. Watch at tomrocksmaths.com (link on profile) #tomrocksmaths #numberphile #parabolicmirror

NEW VIDEO: Direct Sum of Vector Spaces Explained. Features a nice proof showing the two standard definitions are equivalent, and 3 fully worked examples of how to show something is/isn't a direct sum. Thanks to @proprepeducation for supporting the series! Premieres today at 3pm - watch at tomrocksmaths.com (link on profile) #tomrocksmaths #oxfordlinearalgebra #directsum
