The escape velocity is a way of measuring the exact amount of energy needed to reach the lip of the well -- and have no energy left over for walking away. When a ball is thrown up into the air from the surface of the Earth, it does not have enough energy to escape. So it falls back down.
The American Chestnut is a large, broad tree that produces an edible chestnut. Large leaves turn yellow and brown in autumn. At least two American Chestnuts planted no more than 200' apart are required for producing chestnuts.This tree was very common before blight wiped out most of them in the early 1900's.ur pure American Chestnuts come from mature parents who have survived the blight and are producing chestnut seeds. For now, the possibility of American Chestnuts getting the blight sometime in their life is a real possibility.
The chestnut group is a genus (Castanea) of eight or nine species of deciduous trees and shrubs in the beech family Fagaceae, native to temperate regions of the Northern Hemisphere.resh chestnut fruits have about 180 calories (800 kJ) per 100 grams of edible parts, which is much lower than walnuts, almonds, other nuts and dried fruit (about 600 kcal/100 g). Chestnuts contain very little fat, mostly unsaturated, and no gluten.
