Nome, Alaska USA
√ Two 2 1/2 pound GPS-guided UAVs that tolerate extreme cold helped bring fuel to snowbound Nome, Alaska over two weeks in January. On daily photographic missions, the Aeryon Scouts helped University of Fairbanks researchers map ice thickness in the frozen harbor so a Coast Guard icebreaker could slowly guide a Russian fuel tanker close enough to pump the fuel to shore.

In 1589, at the age of 25, Galileo Galilei toiled up the 294 steps of a 55-meter bell tower in Pisa, Italy, where he was tutoring math students at the time.

According to his pupil and later biographer, Vincenzo Viviani, Galileo carried with him two cannonballs, one twice the weight of the other. When he reached the top of the tower, he went to the lower balcony of the tilted structure and dropped the two balls simultaneously.
