A teacher should be more clever than a student. Why didn't teacher of James Watt invent steam engine then?
...funny
I heard that in one Czech show.

I heard that in one Czech show.Avagadro's constant = 6.02x10^23 atoms per mole.
Moles = Mass/Molar Mass, Molar Mass of water = 16+2 = 18
According to here, there are 7.5x10^18 grains of sand in the world.
Let's say there is 100ml in a glass of water. That is 100g of water.
Therefore there are 100/18 moles in this glass of water, = 5.5556 Moles.
This is 5.5556*6.02x10^23 Atoms = 3.344x10^24 atoms in this glass of water, which is alot more atoms than grains of sand in the world.
Of course, this estimate to the number of grains is probably a long way out, although even this 100ml glass has 500,000x more atoms than this estimate. So in conclusion, a glass of water probably does have more atoms than grains of sand in the world
Another fact to stay on topic [Chemistry related]
One mole of any substance has roughly the same amount of atoms [6.02x10^23] as the number of grains of rice to cover the UK to a depth of 10km.

Crisps always expire on a Saturday. (at least in the uk)
I have some pringles that expire on a thursday, but then again Pringles aren't really crisps.
Speaking of which: Pringles recently lost a court case to stop Pringles being legally labelled as crisps.

Cake or biscuit?
Under UK law, no Value Added Tax (VAT) is charged on biscuits and cakes — they are "zero rated". Chocolate covered biscuits, however, are subject to VAT, currently 15%. McVities classed its Jaffa Cakes as cakes, but in 1991, this was challenged by Her Majesty's Customs and Excise and the case ended up before the courts.[9] This may have been because Jaffa Cakes are about the same size and shape as some types of biscuit, and particularly because they are commonly eaten alongside, or instead of, traditional biscuits. A question that the court asked itself was "what criteria should be used to class something as a cake?"
McVities defended its classification of Jaffa Cakes as cakes. In doing so it produced a 12" Jaffa Cake to illustrate that its Jaffa Cakes were simply miniature cakes.[10]
McVities argued that a distinction between cakes and biscuits is, among other things, that biscuits would normally be expected to go soft when stale, whereas cakes would normally be expected to go hard. It was demonstrated to the Tribunal that Jaffa Cakes become hard when stale. Other factors taken into account by the Chairman, Mr Potter QC, included the name, ingredients, texture, size, packaging, marketing, presentation, appeal to children, and manufacturing process. Contrary to a commonly held belief, whether something is considered a 'luxury item' is not a test for VAT purposes.
Mr Potter ruled that the Jaffa Cake is a cake. McVities therefore won the case and VAT is not paid on Jaffa Cakes.[11]

That's why Jaffa-cakes are so awesome! Go jaffa-cakes :woohoo:
Haha, people that are involved in law are so pedantic.
Hope it hasn´t been posted yet, but 1 hp is not always 1 hp. Why?
1 kW = 1,359622 PS (in Germany)
1 kW = 1,341022 bhp (in GB + USA)
Think that also has to do something with metric and imperial systems, but I´m not sure.

ps != bhp.
1hp always equals 1hp. But 1hp does not equal 1ps So 1kW = 1.36PS = 1.34hp
PS (Pferdestärke) is 'metric horsepower'.

Even tho it already had two successors, the ol' Microsoft FS 2002 is still able to get real weather data from the Jeppensen servers via its ingame menu button. Looks like nothing changed on Jeppensens side for 7 years:sleep2:
There is a place in Australia called Denmark.
There is a place in Europe called Denmark.
There are a place a place on Earth called Europe
there is a plannet called earth in the milkyway galaxy
If the enemy is within range, so are you.
Unless the enemy just has a bigger gun.
this is a mole
His name was Mel Blanc. He voiced many Looney Toons charaters e.g. Bugs Bunny, Yosemite Sam, Foghorn Leghorn. Many more as well.
He died in 1989, and the engraving on his tombstone says "That's all folks"
- On 2nd July it will be a year without a patch... :worried:
Yea, because a test patch counts...
Why shouldn't it?
