Even though the engine is the biggest concern with regard to breaking in a new car, drivers should also be mindful of the brakes and tires. Their surfaces aren't yet optimized for performance because they may have a film left over from the manufacturing process. Since tires and brakes both work by creating friction, they're less efficient if they're too smooth.

If you can see Polaris, i.e., the North Star, you'll know which way is north — and, by extension, which ways are south, east, and west too. You'll also know your latitude, as the altitude of Polaris above the horizon is equal to your latitude. And if you have an accurate clock, you can also find your longitude by consulting a table of which stars are due south at the time you're observing." … [Read more...] about How Do We Find Things in the Blackness of Space?
