alfred wegener\njust learned this myself (:

muromets is correct. You can model this yourself using clay. On a cookie sheet, put a half inch of water. On top, put a 1/2 layer of rolled clay. This is what the earth was liked pre-flood. The earth was watered from below. Now break open the center and the water will burst forth (as Genesis describes) and now the clay is covered by the water as the clay sinks. Now pull the clay out toward the corners and the water will display into seas.\nIn order for the continental drift to occur properly, the earth would have had to expand, thus making physics of the covering of the earth with water and its later displacement to be quite possible.

The things he failed to provide he had no way of knowing existed. His observation was correct, and the fossil evidence, glacial evidence, and evidence of matching geologic formations across continents were correct. He failed to provide a credible mechanism to explain the movement of continents. Because it was assumed that oceanic plates were stationary, it was easy to invalidate his hypothesis. That assumption turned out to be wrong. \n\nAt that time the ocean floor was an unexplored and unknown part of the planet. Wegener had no way of knowing that volcanically-active mid-ocean ridges existed in every ocean basin. The mid-Atlantic ridge was known, but no significance was given to this. Wegener had suggested that the continents actually disrupted the ocean floor as they moved, and there was no evidence to support that idea.

A. True.\nThe concept of continental drift was first proposed by Alfred Wegener. In 1912 he noticed that the shapes of continents on either side of the Atlantic Ocean seem to fit together (for example, Africa and South America). Francis Bacon, Antonio Snider-Pellegrini, Benjamin Franklin, and others had noted much the same thing earlier. The similarity of southern continent fossil faunae and some geological formations had led a relatively small number of Southern hemisphere geologists to conjecture as early as 1900 that all the continents had once been joined into a supercontinent known as Pangaea. The concept was initially ridiculed by most geologists, who felt that an explanation of how a continent drifted was a prerequisite and that the lack of one made the idea of drifting continents wholly unreasonable. The theory received support through the controversial years from South African geologist Alexander Du Toit as well as from Arthur Holmes. The idea of continental drift did not become widely accepted as theory until the 1950s in Europe. By the 1960s, geological research conducted by Robert S. Dietz, Bruce Heezen, and Harry Hess along with a rekindling of the theory including a mechanism by J. Tuzo Wilson led to acceptance among North American geologists.\n\nThe hypothesis of continental drift became part of the larger theory of plate tectonics. This article deals mainly with the historical development of the continental drift hypothesis before 1950. See: plate tectonics for information on current ideas underlying concepts of continental drift.

charles darwin proposed theory of natural selected or DARWININISM.It states:\n1.Despite having enormous potential of fertility, the population size of any kind of organism remains within a limit.\n2.It is due to the struggle between members of same species and different species for food, space and mate.\n3.The struggle eliminates the unfit individual.(survival of the fittest).\n4.These favourable changes when accumulated for a long time lead to origin of new species.\n\nHope it helped

Isaac Newton. It would give him a big scare, considering he is most remembered for his laws of gravity.\nOh, and Christopher Columbus........."OMG!    It is flat!!!!"

I'm sure many of the famous astronomers before him like Edwin Hubble, Harlow Shapley, James Jeans (mentioned by person in an interview) where all important to his work.  Check out some of his papers in the Astrophysical Journal or the Astronomical Jounal and check who the references are.

It is sometimes suggested that Ben Franklin was the first to suggest daylight savings in a letter to the Journal of Paris. However he was putting it forward humorously.\n\nt was first seriously proposed by William Willett in the "Waste of Daylight", published in 1907, but he was unable to get the British government to adopt it despite considerable lobbying. The German government introduced it during 1916 to increase productivity in World War I with the British following soon after.

The closest I came to any kind of a real answer was that there was a surveyor by that name who lived in Czarist Russia in 1830 and planned a series of canals to make a river run backward.\n\nhere's the site:  \n\nhttp://www.time.com/time/archive/preview/0,10987,950711,00.html

I think it is Albert Einstein... Einstein stated The Theory of Relativity, breaking down Isaac Newton's The laws of Three Motions and Theory of Gravitation, demonstrated that Newton's theories were only partially right. What is more, scientists believe that there will need more than 200 years for another "Einstein" be born in this world to help the innovation of Physics. Current Mathematics is not adequate for solving Physical problems any more.

Scientific theories behind the origins of sea salt started with Sir Edmond Halley in 1715, who proposed that salt and other minerals were carried into the sea by rivers, having been leached out of the ground by rainfall runoff. Upon reaching the ocean, these salts would be retained and concentrated as the process of evaporation (see Hydrologic cycle) removed the water. Halley noted that of the small number of lakes in the world without ocean outlets (such as the Dead Sea and the Caspian Sea, see endorheic basin), most have high salt content. Halley termed this process "continental weathering".

Edwin Hubble was an astronomer.\nHe was one of the first to show that some "nebulae" were actually separate galaxies outside of our own.\n\nHe observed that light from distant galaxies was redshifted - indicating that they were travelling away from us at very high speeds. This was a key discovery leading to theories of an expanding universe and the theory of the big bang.\n\nHis work is the foundation for modern physical cosmology.

He came up with the Theory of Evolution

Two main reasons:\n\nFirst, he could not explain *how* continents were able to move.\n\nSecond, he suggested that the reate of drift was ten to a hundred times faster than we now know to be true.\n\nI would suggest that, third, the idea is so counterintuitive -- because human lives are so short, in geological terms, continents seem to us to be utterly constant and permanent.

einstein. he just sat in his chair and thought of theories. he did experiments in his mind
