Feel free to add your own gems.
There are seven classifications of snowflakes: plates, stellar crystals, columns, needles, spatical dendrites, capped columns and irregular forms.
You didn't know that, did you?
Cheers,
Steve

Love that word, Stevie...'factoid'
Did you know that every time you lick a stamp, you consume one tenth of a calorie

We share at least 25% of our genome with daffodils.

That is a very elegant piece of maths, Steve.

Here's a good one.
Did you know that all over the world, the sails on every windmill rotate counter-clockwise. Everywhere but in Ireland.
I have no idea why that should be.
Depends on which way the blades are angled when the sails are made, they could be made to turn either way.
If the windmill components were aquired from a common manufacturer, it would be likely they would all turn the same way.

(3) When hydrogen is fused into helium, matter is converted into energy. The Sun, like most stars, is powered by the fusion of hydrogen into helium (what the textbook misleadingly calls `hydrogen burning'). You may well ask, ``Where does all that energy come from when hydrogen is fused into helium? Isn't energy conserved?'' There is another question you can ask. The total mass of four hydrogen nuclei is 6.693 x 10-27 kilograms. The mass of a helium nucleus is 6.645 x 10-27 kilograms. Thus, there is a loss of 0.048 x 10-27kilograms every time a helium nucleus is formed by fusion. The loss is small, but real. You may then ask, ``Where does that mass go when hydrogen is fused into helium? Isn't mass conserved?''
Albert Einstein provided us with an answer to our questions. He pointed out that mass can be converted into energy, and vice versa. The `exchange rate' between mass and energy is given by the famous equation E = m c2where E = energy, m = mass, and c = the speed of light in a vacuum (300,000,000 ometers/second). Thus, the total amount of MASS+ENERGY is conserved.
Every second, as we have seen, the Sun creates E = 3.9 x 1026 joules of energy. To balance the books, every second the Sun destroys m = E/c2 = 4.3 x 109 kilograms of mass. This mass loss, equivalent to more than 4 million tons per second, is accomplished by fusing 600 million tons of hydrogen into 596 tons of helium.

A man can outrun a cheetah over a distance of four miles (6.4km) during the hottest time of the day.
