A dazzling white smile might be essential for Hollywood stars. But those glow-in-the-dark teeth aren't right for most people, according to scientists who have worked out a formula for the perfect smile. They took several factors into account, including the size and width of each tooth, the curve, colour and shape of the teeth and the overall width of the mouth. picked by AutumnLotus 2 years ago

This is one of the two most perfect spheres ever. Exactly one kilogram—Imperial units be damned forever—smooth to the nearest 0.0000000003 meter (1.18110236 × 10-8 inches), and round to within 0.00000005 meters (1.96850394 × 10-6 inches).

The Space Shuttle is an amazing engineering accomplishment. It is also an incredible programming accomplishment. The software never crashes. It is bug-free. It is perfect, as perfect as human beings have achieved. The last three versions of the program -- each 420,000 lines long-had just one error each. Commercial programs of equivalent complexity would have 5,000 errors picked by bernardblack 6 months ago
