Gross Miscalculation

Within weeks after the 1990 launch of the Hubble Space Telescope, observers noticed a serious problem with its optical system, which was returning fuzzier-than-expected images. Scientists discovered that the multi-billion-dollar telescope's mirror was barely 2.3 micrometers off from the required shape -- a small miscalculation that caused very large, very expensive problems.

Beverly Willis, who penned this letter to the editor of the Catonsville Times, also made a serious miscalculation regarding the distance of her car from the curb. She seems to find it strange that it would be "illegal to park more than 12 feet from the curb." By my calculations, that would put you on the other side of the street. So yes, Beverly, it really is "that big of a deal if [you're] parked 18 feet from the curb as opposed to 12." The extra six feet will, indeed, obstruct the public safety of your neighborhood. Thanks for asking.
