The condemned was locked  inside the belly of the bull and fire was set under it, heating the metal until the person inside roasted to death. Read more

## Bernoulli’s theorem

A body orbiting around a planet is in equilibrium between two forces: the centrifugal force and the gravitational force

where Fc is the centrifugal force, Fg is the gravitational force, m1 is the mass of the orbiting body, m2 is the mass of the planet, v is the speed of the body while orbiting, r is the distance of the body from the center of the planet, G is the gravitational constant

## The Earth map used in the UN flag: 33 sectors

A grid, probabl
y representing parallels and meridians, divides the Earth in 33 sectors. Another special number is 11, 33 being a multiple of it. You probably wonder what  it means and what relation have these numbers with the Earth.
