Puzzle 119. LONG DISTANCE LOVERS |
|
|
Jim and Carol were two long distance lovers. Jim lived in Chicago, and Carol lived in New York. Jim was eager to get married soon. Carol, who wanted to concentrate on her career, wanted to delay for at least two years. Knowing that Chicago and New York have a time difference on an hour, Carol told Jim over the phone that if he proposed at a time when both Chicago and New York have the same time, she would agree to get married right away. Within a month, Jim proposed, and Carol agreed. And the married couple, at least for Jim, lived happily ever after. How did this happen? When did Jim proposed?

Bits and Beyond... PRIME NUMBERS Prime numbers have captured the hearts of many mathematicians for centuries. During 18th century, mathematician Christian Goldbach (1690-1764) wrote to Leonhard Euler that he believed it could be shown that every even integer greater than 2 is the sum of 2 primes. For example, 30 = 23+7 and 36 = 13+23. Until now, this conjecture has neither been proved or disproved.
