Why has this photo of Trump gone viral?

1 Comment

This [possibly edited] photo of Trump is trending. But why? Is it his luxuriant swept back hair? His coy over-the-shoulder invitation to join him in a frolicsome adventure? The lush greenery of the White House south lawn? Please submit your best guess in the comments.

Pi Clacks

1 Comment and 2 Shares

In 2003 mathematician Gregory Galperin of Eastern Illinois University offered a remarkable way to calculate π: Launch two masses toward an elastic wall, count the resulting collisions, and you can generate π to any precision, at least in principle.

“On the one hand, our method is purely mathematical and, most likely, will never be used as a practical way for finding approximations of π. On the other hand, this method is the simplest one among all the known methods (beginning from the ancient Greeks!).”

The video above, by 3Blue1Brown, gives the setup; the continuation is below. Via MetaFilter.

Area Matters

1 Comment and 2 Shares

area matters 1

If you know the vertices of a polygon, here’s an interesting way to find its area:

  1. Arrange the vertices in a vertical list, repeating the first vertex at the end (see below).
  2. Multiply diagonally downward both ways as shown.
  3. Add the products on each side.
  4. Find the difference of these sums.
  5. Halve that difference to get the area.

area matters 2

This works for any polygon, no matter the number of points, so long as it doesn’t intersect itself. It’s a slight restatement of the shoelace formula.

(Thanks, Derek, Dan, and Kyle.)

Can confirm. This thing was amazing for the early 90's.
