Paul Harrell did not kill anyone in 1967 because he was born in 1966 - removed by Facebook
Just more proof that macho men always tell tall tales. Mundus vult decipi, ergo decipiatur.

Odd YouTube auto-generated captions glitch
Its language recognition and translation software are excellent, so I'm wondering how it could confuse English with Czech. Link: https://www.youtube.com/watch?v=TyQ0hzq4hYE
See what auto-generated captions you get.

Brahmagupta's formula, Heron's formula, and the circumscription of polygons
I noticed recently that the formulas of Heron and Brahmagupta have the same structure, and thus I conjecture that any polygon with sides (a, b, c, d, etc.) and a semi-perimeter (s) that can be circumscribed will have an area (A) given by the following equations:
s = (a + b + c + d ....)/2
A = sqrt[(s - a)(s -b)(s - c)(s - d)....]
Heron's formula (for the area of any triangle)
s = (a + b + c)/2
A = sqrt[(s - a)(s -b)(s - c)]
Brahmagupta's formula (for any cyclic quadrilateral)
s = (a + b + c + d )/2
A = sqrt[(s - a)(s -b)(s - c)(s - d)]
