A cool calculation that you can do with your kids, hints that about 1000 years ago, each of us had around 8 billion ancestors. However it is estimated that around the year 1000 AD, there were only about 300 million people in the world. How does that work?

Some kind of average A(a,b) of two numbers a and b should at least:
i) always be a value between a & b
ii) satisfy A(a,b) =A(b,a)
iii) satisfy A(ka,kb)=kA(a,b).
If A(a,b) behaves like an average, must f^(-1)(A(f(a),f(b)) behave like one too for any invertible function f?

Prove that each positive integer point on the vertical axis is collinear with two points with integer coordinates on the curve of the y = -x^2 graph. With how many such pairs is the point (0,1000) collinear?

Finished day 1 of learning #julialang from @ynazarathy 👩💻
And for myself, I have to check that Julia works with #rmarkdown (it does!)

A self-referential die has faces labeled with fractions so that the chance of seeing the fraction you roll is the fraction you see. There are four 6-sided SR dice. There are zero 2-sided SR dice (coins). For world fame, find an explicit formula for the number of N-sided SR dice.

Given an a-by-b rectangle, a square of the same perimeter has side the arithmetic mean of a & b; the same area, the geometric mean of a & b; the same diagonal, the quadratic mean of a & b. A square of side the harmonic mean of a & b has what in common with the original rectangle?

Have been using Facebook mobility data to map social distancing and how it changes in Australia at maths.adelaide.edu.au/lewis.…. tl;dr: social distancing has been gradually waning over the past 3 weeks or so, across all states.

Oh what fun to do tie-folding with such a fabulous community of high-schoolers in the DC metro area! @mrchasemath For those curious, here's the unsolved math (Artin's conjecture) behind the scenes. youtu.be/y3HxU4WMvdA @GlobalMathProj

Is there a rectangle that can be cut with three straight-line segments into three pieces of equal area, equal perimeter, and each possessing an equal portion the the rectangle's perimeter? If so, what are its dimensions?

It is possible to divide a square into three pieces so that all three pieces have the same area, the same perimeter, and possess the same proportion of the square's perimeter. Can the same, for sure, be done for any non-square rectangle?

It is poss to divide a square into 3 pieces of equal area & equal area; or into 3 pieces of equal area with equal portions of the square's perimeter. Possible to divide a square into 3 pieces with equal perims & equal portions of the square's perimeter? With all three features?
