So, I had a heart attack and bypass surgery brian.moonspot.net/so-i-had-a-hea…

@divbyzero Let me know how it turns out, if you try it.

I may try to making some aperiodic monotiles like these Penrose tiles that @wilderlab gave me a few years ago. Who knows if my home cutting machine will cut these flexible magnetic sheets though...? Worth a try. amazon.com/Colored-Magnet…

Did you know that any two polygons with equal area are "scissors congruent"? I outline a simple proof in this column for @QuantaMagazine. #math #geometry quantamagazine.org/simple-geometr…

@panlepan Perfect totient numbers

@wilderlab Wow ! A sort of perfect number using iterations of Euler's totient function. Do these numbers have a name ?

For the 327th day: φ(327) = 216, φ(216) = 72, φ(72) = 24, φ(24) = 8, φ(8) = 4, φ(4) = 2, φ(2) = 1, and 216 + 72 + 24 + 8 + 4 + 2 + 1 = 327

Numbers and squares: 3869 = 62²+05² 6205 = 38²+69²

For the 324th day: √324 = 3 • (2 + 4)

Fours and exponents:
4624 = 4⁴+4⁶+4²+4⁴
595968 = 4⁵+4⁹+4⁵+4⁹+4⁶+4⁸

Exponents in reverse:
48625 = 4⁵+8²+6⁶+2⁸+5⁴
397612 = 3²+9¹+7⁶+6⁷+1⁹+2³

Happy Halloween! 🎃 👻
