NW Parabolas can be seen in nature or in manmade items. Located in an area known as Little Paris, the replica of the Eiffel Tower near Sofia, Bulgaria, features a restaurant about one-third of the way up the building. Since Eiffel did not seem confident in estimating the wind torque on the tower, he "overdesigned" the bottom section, beefing it up for safety reasons. Note: Franz Reichelt (16 October 1878 4 February 1912), also known as Frantz Reichelt or Franois Reichelt, was an Austrian-born French tailor, inventor and parachuting pioneer, now sometimes referred to as the Flying Tailor, who is remembered for jumping to his death from the Eiffel Tower while testing a wearable.
