Did you know that a knight on an infinite chess board is 24/13 times faster then a king?!
A proof of this fact was posted on the archives by Christian Táfula, where he solves the problem for the (a,b) knight, a generalisation of the beloved (1,2) knight.

Knights are 24/13 times faster than the king

I am sitting in a cafe at a bookstore and two sisters are at the table over, the younger 8 or 9, the older looks like she might be starting highschool this year.
They are having the most wonderful exploration of the differences between 'estimation' and 'guestimation'.
I am taking notes.

What I have been thinking about is how is the culture of this space evolving and how do we participate in creating the kind of culture we want to be a part of ✨

Excellent article from Ben Orlin about not worrying so much about easy vs hard and thinking instead about being welcoming and challenging. #iTeachMaths

TEACHER VOICE: Instead of worrying about whether math is easy or difficult, let’s make it welcoming - The Hechinger Report
