The rule, implemented by the U.S. Golf Association (USGA) and Royal and Ancient Golf Club (RA), means that from the start of 2010 the U-shaped grooves on wedges will be banned in favor of V-shaped grooves, with the intention of rewarding accurate driving over distance hitting.

The side-view mirrors on most cars are flat, and while they give drivers an accurate sense of the distance of cars behind them, they have a narrow field of view, leaving a space behind the vehicle -- the blind spot -- that a driver can't see.

Radar measurements are incredibly accurate: we get the distance to the asteroid very, very precisely, and we can also get its velocity relative to us.
