Stephen J. Hawking By Rachel Finck
Stephen Hawking was born in January of 1942 in Oxford, England. He grew
up near London and was educated at Oxford, from which he received his BA in 1962,
and Cambridge, where he received his doctorate in theoretical physics. Stephen
Hawking is a brilliant and highly productive researcher, and, since 1979, he has
held the Lucasian professorship in mathematics at Cambridge, the very chair once
held by Isaac Newton. Although still relatively young, Hawking is already being
compared to such great intellects as Newton and Albert Einstein. Yet it should
be noted that since the early 1960s he has been the victim of a progressive and
incurable motorneurone disease, ALS, that now confines him ...

the entire of the physical world; a theory that
would stand as a complete, consistent theory of the physical interactions that
would describe all possible observations. Our attempts at modeling physical
reality normally consists of two parts: a) A set of local laws that are obeyed
by the various physical quantities, formulated in terms of differential
equations, and b) Sets of boundary conditions that tell us the state of some
regions of the universe at a certain time and what effects propagate into it
subsequently from the rest of the universe. Presently, physicist are still
trying to unify two separate theories to describe everything in the universe.
The two theories are the general theory of relativity and quantum mechanics.
Albert Einstein formulated the general theory of relativity almost
single-handedly in 1915. First, in 1905, he developed the special theory of
relativity, which deals with the concept of people measuring different time
intervals, while moving at ...

general relativity cannot be defined as a singularity. This means that general
relativity cannot predict how the universe should begin at the big bang. Thus,
it is not a complete theory. It must be paired with quantum mechanics.
In 1905, the photoelectric effect was written about by Einstein, which
he theorized could be explain if light came not in continuously variable amounts,
but in packets of a certain size. A few years earlier, the idea of energy in
quanta had been introduced by Max Planck.
The full implications of the photoelectric effect were not realized
until 1925, when Werner Heisenberg pointed out that it made it impossible to
measure the position of a particle ...
