Here is some discussion as to why red represents danger (incidentally Goober, I found this by Googling for 'red danger physics', same as you).

In ancient India, a wealthy merchant died and left his estate to his three sons. The oldest son got half, middle son 1/4th and youngest son, 1/5th.

A question for you Judge Goober.

How much wood could a woodchuck chuck if a woodchuck could chuck wood?

As to the wood chick - size, diameter, and i do not know.

A woodchuck could chuck as much as a woodchuck could chuck if a woodchuck could chuck wood....

Doesn't really settle the issue though, it reiterates some of the points made here. And in fact red often doesn't mean danger, it means something more or less opposite. Consider apples, strawberries, roses, tomatoes... The use of red for stop lights and brake lights and whatnot has more to do with habit and psychology than physics. I think attempts to link it to the colour of blood or it being scattered less in the atmosphere is the post hoc fallacy. You'd have to be a mighty long way away from a stop light or brake lights for Rayleigh scattering to make any difference to their visibility, far enough away that you could reasonably ignore them.

Who got the other 20th of the estate?

As man has sailed longer than we have had railroads I would refer to the old sailing adage

Red sky in the morning, sailors take warning. Red sky at night, sailors delight

"Red sky in the morning, sailors take warning. Red sky at night, sailors delight."

As SJP posed the question the ball for the most part is in his court.

I turn polar bears white

I make guys have to pee

And girls comb their hair.

I make celebrities look stupid

And normal people look like celebrities.

I turn pancakes brown

And make your champagne bubble.

If you squeeze me, I'll pop.

Here is one from Iraq (that is the advantage of having international friends, one learn so much about other countries).

Two friends from Basra once started on a journey. They made camp for night and they spotted a stranger. They invited him to share a meal with them. Friend A had five loaves of bread, friend B had 3. They divided each loaf into three parts and each partook of one.

At the end of the meal, the stranger thanked them, gave them 8 dinars and left. Now the two friends had an argument. Friend A said that he should get 5 dinars and B should get 3, since he contributed five loaves his friend contributed only 3. Friend B said that since they are friends, it is only fair that they split it evenly four each.

So, what is the fairest way of splitting the eight dinars? Hint: they are both wrong.

Amended answer.......A gets 7 B gets 1.

Here is the answer to the Iraqi puzzle. It is not really a puzzle, one simply has to work out the arithmetic. It constitutes a puzzle simply because the answer is rather unexpected.

Totally there were 8 breads (5 from A, 3 from B), each cut into three pieces. So there were 24 pieces, each ate 8. Friend A had 5 loaves, 15 pieces were made from that. He ate 8, which means he gave 7 to the stranger.

Friend B had 3 loaves, out of which 9 pieces were made. He ate 8, giving 1 to the stranger.

So friend A gave 8 pieces to the stranger, friend B gave one piece. So the fairest split of the 8 dinars would be, friend A gets 8, friend B gets 1.

But how do you know that this took place in Islamic Iraq? This could have taken place in ancient Mesopotemia. Do we really know what the customs regarding accepting money etc. were in those days?

Here is another one from ancient India. People in Middle East and Far East seem to be fond of puzzles, many of which are mathematical in nature. If kids are exposed to such puzzles from the childhood, they probably develop a liking for mathematics. I suppose that would explain why people from there excel in math and sciences.

In ancient India, a king wanted to accomplish some great task (which one, does not concern us). The reward for whoever completed the task was gold coins equal to the weight of king’s favorite elephant.

Well, a man did accomplish the task and was eligible for the reward. But there was a problem. How does one weigh an elephant? The king didn’t have a big enough scale whereby he could put the elephant on one side and balance the other side with gold coins. It would take a long time to build such a scale. Besides, it would be expensive.

He described the difficulty to the reward winner. The winner said “Your Majesty, I am not a greedy or fussy man. Give me gold coins approximately equal to the weight of elephant and I will be satisfied.

Which was something. But still question remains, what is the simplest way to measure out gold coins approximately equal to the weight of an elephant (there is no scale available).

Lead the elephant to a pool of water of known volume then measure the amount of water it displaced

If you tied a piece of string around the equator, and another one around a basketball, then added 1" to the length of each string, which one would be higher off the original surface?

Dinars are used by more Arab / Muslim countries that Christian countries - I went with the odds.

You submerge the elephant in a tub of water and get the volume of the water that spills over. Elephants are very close to the same density as water, gold is about 19 times the specific gravity so give the guy 1/19 of the volume of Au.

'Fraid not, Spade was right. The relationship between the circumference and the diameter of a circle is perfectly linear, increase the circumference by 1 inch and the diameter increases by about a third (1/pi, actually) of an inch, regardless of the original size of the circle.

Here's one of my favourites, which in my experience people either get immediately or never get at all. If a hen and a half lays an egg and a half in a day and a half, how many eggs can 9 hens lay in 9 days?

[Hint: it's not 81]

Anyone feel up to discussing the old Monty Hall problem again?

half a hen cannot lay an egg, and a hen cannot lay 1/2 an egg.

In real life, that's true, but mathematically you can deal with them as if they could. If five hens lay four eggs, for example, we could say that on average each hen lays 4/5 of an egg and half a hen lays 2/5 of an egg.
