... of letters written by
the 7th century writer, Theophylactus of Simocatta. After that he wrote an
astronomical discourse that laid the foundation of his heliocentric theory; the
theory that the sun is the center of our solar system. However, it was 400 years
before it was published.
After leaving his uncle, he wrote a treatise on money, and began the
work for which he is most famous, On the Revolution of the Celestial Spheres,
which took him almost 15 years to write. It is ironic that what he devoted a
good part of his life would not be published until he was on his deathbed.
His Theory:

... explode! But this is
nothing to worry about... unless you have carpeting. Although we modern
persons tend to take our electric lights, radios, mixers, etc. for
granted. Hundreds of years ago people did not have any of these things,
which is just as well because there was no place to plug them in. Then
along came the first Electrical Pioneer, Benjamin Franklin, who flew a kite
in a lightning storm and received a serious electrical shock. This proved
that lightning was powered by the same force as carpets, but it also
damaged Franklin's brain so severely that he started speaking only in

chance, and it makes the theory of evolution plausible. If neo-Darwinism
is correct then numerous small successive changes guided by natural
selection gave rise to all animals and plants.
I will prove that natural selection is not a creative process. Its
primary function is to preserve the status quo. Thus, new structures and
organs must arise through chance. Natural selection can only pre ...
