A sling shot is an elastic band mounted on a stick that looks like a 'Y'. It has a small leather pocket in the middle of the elastic for holding the ammunition. The ammunition can be a marble, or a small rock, or something else that will do damage. The operator inserts the ammunition and pulls back on the elastic strap and lets it go while aiming at the target.
Experiments in the early 20th century could not be explained by classical physics (developed by Galileo, Newton, etc.). Classical physics worked fine on a larger scale. However, on an extremly small scale it was flawed. Scientist started looking at things on an atomic level. This was the beginning of Quantum mechanics. This science was greatly advanced during WWII, when the military use was realized. Hope this helps some
Einstein was best known as a theoretical physicist, but working in a patent office in Germany, he also became a less well known inventor. In physics, Albert Einstein is responsible for developing his Special and General Theories of Relativity (E=Mc2), and he did some important work on the photoelectric effect.
He co-invented a type of refrigerator with no moving parts; patent number 1781541. An electromagnetic pump; patent number GB303065, a self adjusting camera; patent number US2058562, and a sound replication device; patent number DE590783. Along with dozens of other patents worldwide. Its no that he had invented anything really, because he is a physcist, but he had come up with E=mc squared. And the relevance between light and its reflection.
well I heard it was a man namd Buzil from England,London in 1963 in october the something. thank you and good night
Historians do not know who or when mankind "invented" a time-keeping device or "clock". Probably thousands of years ago when someone stuck a stick in the ground and saw the shadow of the sun move across the ground, known as a Sundial.
In ancient Egypt water clocks were used to keep time.
The civil day in ancient cultures was made up of watches. The length of the watch varied with the season, and were called seasonal or temporal hours.
The word CLOCK came into use in the 14th century AD.
The science or art of measuring time or making timepieces is known as Horology.
The name CLOCK, which originally meant BELL, came into use when there were very large mechanical time indicators installed in bell towers in the late Middle Ages. These Clocks were not accurate.
The origin of the word Clock
Clokke = Middle English
Clocca = Medieval Latin
Cloc = Celtic and Old Irish
Clugge = Old English
Glocka = Old High German
The word Bell has been used meaning to: chime, cry out, sound off, clamor and war.
