in the 50's an American chemist Stanley Miller who subjected a mixture of the supposedly early atmospheric gases (CH4, NH3, H2 and H2O vapor) to an electric discharge. The products that he obtained included several amino acids, fatty acids, and simple sugars. Similar results, using ultraviolet radiation instead of electric discharges demonstrated that solar radiation may have been chiefly responsible for promoting reaction among the gases of the early atmosphere. (to cut to the chase)
As the primitive anaerobic organisms multiplied, the nutrients were depleted and waste products accumulated. Some cells, which then evolved a different means of obtaining food and energy, eventually emerged as the aerobic organism that first accomplished photosynthesis with the aid of chlorophyll. The carbon dioxide accumulated in the atmosphere and oceans by anaerobic and volcanic activity was converted photosynthetically to carbohydrates and gaseous oxygen:

Fear of flying Welcome aboard

Sep 7th 2006
From The Economist print edition

...."Also, please keep your seat belt fastened when seated, even if the seat-belt light is not illuminated. This is to protect you from the risk of clear-air turbulence, a rare but extremely nasty form of disturbance that can cause severe injury. Imagine the heavy food trolleys jumping into the air and bashing into the overhead lockers, and you will have some idea of how nasty it can be. We don't want to scare you. Still, keep that seat belt fastened all the same."

Using the formula h(t) = -1/2gt^2 + vt+s, and where "v" is initial velocity, "s" is initial height, "t" is time, and g is 32 ft/sec/sec.

Also, after 4 seconds it hits the ground, and you are standing on a building.
