It's reasonable to assume that an ice tray full of hot water will freeze slower than a ice tray full of room temperature water. But because much of the hot water will evaporate, the opposite is true.

For millenia, it was assumed that our sun orbited the Earth, based on the 'self-apparent' geocentric model. The question is, how would the incorrect model of a truly geocentric universe appear?

Eating any animal too often

This one puzzles me. If you want to take 1000mg of Vitamin D, will taking 2 x 500mgs of Vitamin D equal 1000mg of Vitamin D? It would appear that the answer would be yes, but is it?

Boy, the sun sure does look like it’s moving around the earth.

The "Monty Hall Paradox" is one of my favorite examples of this: If there are 3 curtains and a prize behind one of them, you have a 1/3 chance of guessing the prize. After you guess, the host reveals one of the other non-winning curtains. The host then asks if you want to stick with your original guess, or if you want to switch. To most, it seems that there are 2 curtains, and you now have a 50/50 chance either way, but in fact you should switch your guess, as you then have a 2/3 chance of winning. [en.wikipedia.org]

If one spaceship is approaching another at 3/4 the speed of light and the other is traveling towards the first one at 3/4 of the speed of light, it is entirely reasonable to say that they are approaching each other at 1.5 times the speed of light.

Not to put FDR down but I always thought, "..the only thing we have to fear is fear itself " was a bit odd.

If one or two drinks calms your nerves, ten will really help...

If I can finish getting ready to go out in 10 minutes, it seems reasonable that my wife could achieve the same in under an hour. But noooooooo.

Taking 2 Tylonol or Motrin works better than 1, so taking 5 or 6 would work even better. I still know people who do this.. Not true and not safe.

It seems reasonable that a tornado spins because of the Coriolis effect, like hurricanes do. However, this is incorrect. The Coriolis effect does not have much influence on such a small scale. It is not responsible for the spin of a tornado (that's mostly wind shear,) and it is not responsible for the spin of the water flowing down a drain.

It is reasonable to see a move toward independence of thinking by rejecting gods, but wrong to believe that a step in a direction represents actual arrival at the destination.

It's reasonable to assume on any given day that you won't die, but one day you're going to be wrong.

...too dark? Probably too dark. ¯_(ツ)_/¯

Pineapples don't grow on trees. They should but they don't. Bananas grow upside down. How? They do though. Coconuts are not a nut, but a fruit. They shouldn't be a fruit but they are. Strawberries are not a berry

It could be reasonable to assume from four feet away two identical plain bottles both containg clear liquid are full of water.. maybe you have been told it's water. So it would be reasonable to assume one was not vodka ? but one is vodka .. i don't know if this helps or i ust entered a league of proffesional wafflers.. i don't like vodka much lol

A diamond is forever and yet a good hit of liquid oxygen reduces it to carbon in a second

Deer crosing, speed limit, happy medium thought mediums were serious.
