Any unrestrained liquid in space will form a perfect sphere.

I guess first off I should define what is meant by 'unrestrained.' Here on Earth, whenever we see falling liquids they obviously do not take the form of a perfect sphere (have you ever drawn a round raindrop before?). This is not for a lack of 'trying' on the liquid's part; there are simply other forces at work here on Earth that do not allow liquids to become completely spherical. The two culprits that 'restrain' liquids on Earth are gravity and the atmosphere. Gravity keeps the liquid moving toward the Earth and the gases in the atmosphere provide an uneven drag, with both factors resulting in raindrops that are flattened out and deformed.

You weigh less at the Equator

The reason for this is that Earth bulges outward at the Equator because of the planet's rotation and its tendency to stay in a straight line while moving. This creates a gravitational field that is uneven, with more pull on the poles than in the middle. Because of this bulge, a person standing at the Equator is really further from the majority of Earth's mass than a person standing at either of the poles. But don't get your hopes up too much - the weight difference is a mere 0.5%! That's less than a pound for anyone weighing less than 200 pounds.

Albert Einstein’s brain was stolen after he died.

Tiny metal electrodes are attached to Albert Einstein's
head to pick up impulses from his brain and to
magnify and record them for study in 1950 in
Princeton, N.J. Dr. Alejandro Arellano kneels
beside him.

The man who performed the autopsy on Einstein’s body shortly after he died was a Princeton pathologist by the name of Thomas Harvey. Harvey removed the brain for examination, as is customary during autopsies, but he never replaced it. At the cost of his job and reputation, Harvey instead placed it in a jar of formaldehyde and took it home!
