I gave a hint on how one can approach the proof, but you are welcome to share other ideas. Have fun! ❤️

It might be only a special case of a more general theorem by Besicovitch, but it’s not easy to do! Have fun! 🔥 Found in „Mathematical Problems and Puzzles” by S. Straszewicz.

Solved this one and generalized a few weeks ago with my younger brother. A lot of fun!

It’s a short one… or maybe not? Who knows. Me? Perhaps. You? When you solve it. So… go ahead! And solve it! … did you solve it? P.S. Mathinity Sunday Challenge is officially back!

√7 is missing from this viral double cube, and… it’s not a coincidence. But it took over 2000 years to find the real reason why √7 and many other numbers are missing. Full story on my YouTube channel.

I’ve pulled a few all-nighters just to make it happen. And it was totally worth it. „√7 is missing – and it took 2000 years to find the real reason why” is LIVE ON YOUTUBE. Enjoy! Link in a reply!

I'm starting a PhD in Mathematics at @JagiellonskiUni ! 🥳

Cool non alternating series to calculate, what else would you like to do on this beautiful Sunday evening? Have fun! 👑
