I think this is a very Nice man because i'm doing a project in geometry and i got stephan hawking's name.

he is infact the greatest mind the world has even seen.

I don't know about the greatest mind the world has ever seen. He is great because he came at the right time. There is no reason any other great scientist couldn't be considered the greatest, "If I appear to have seen furthur than others, it is because I have stood on the shoulders of giants."

Max Planck was probably the greatest physicist the world has ever seen, but Stephen Hawking's books make for interesting reading, nevertheless.

I enjoy his newest topic...multiverse theory. In this theory, the particle wave history is examined. The idea is that each particle has a history path that is infinite and that a particle will occupy a particular point in its history at any given time. The logical conclusion of this concept is that all possible arrangements of the stuff that makes up the universe will occur. Everything that can happen will happen. The multiverse approach defies the closed system view of the universe and instead suggests that there are infinite universes, one for each particular point of a particle's wave history. So what are the probems with this theory? First, it is not scientifically testable. because we are isolated to our own universe, observational evidence is out of our grasp when we consider other universes. It is a purely theoretical suggestion. Second, our instruments of measurement present a philosophical problem. Does an instrument of measurement automatically change the phenomenon under investigation? Most physicists agree that no measurement device is independent from the same event which it measures. In multiverse theory, the measurement device M is said to quantify a property X and a property Y, where X is one part of a history for particle A and Y is another. In theory, both X and Y merely correspond to behavior of particle A, but that each is its own history. In another universe X and Y may be present or may not, as the property is conditional, whereas a particle history is unconditional in one important sense...it is forever. What type of logical argument can be made, in general, that accounts for all events along the line of a particle wave history? For example, if we say "the history of particle A subsumes all possible properties of A." "X has been shown to be a property of A." therefore, the history of particle A subsumes X."
