Five things you may or may not already know:
Jaws opened on 409 screens on its first weekend in 1975, which was considered a huge number for what was then a "wide" release. Blockbusters often open on 10 times that number now.
If the Earth were reduced to the size of a billiard ball, it would be just as smooth as what you'd find on a pool table. (How's that, you wonder, given we have Everest and ocean troughs? Read here.)
Apart from being a great wine-growing region, California also produces scores of different types of cheese ... about 250, in fact. The state's cheese producers make about 100 types of flavoured and spiced cheese alone. (And, of course, Monterey Jack, which dates back, in one form or another, about 200 years.)
The wife of Wilhelm Conrad Röntgen made medical history in 1895, when she allowed her husband to make the world's first X-ray, using her hand. The experiment revolutionized diagnostic technology.
Seaweed has been used to make everything from medical products to food; Toyota is hoping now to develop a car.
