“When Kepler found his long-cherished
belief did not agree with the most precise observation, he accepted the
uncomfortable fact. He preferred the hard truth to his dearest illusions; that
is the heart of science.”
Carl Sagan
Physics
Class
"Physics (Greek:
physis - φύσις), in
everyday terms, is the
science of
matter
and its
motion. It is the
science that seeks
to understand
very basic concepts such as
force,
energy,
mass, and
charge. More
completely, it is the general analysis of nature, conducted in order
to understand how the
world around us
and, more broadly, the
universe, behaves.[2][3]
Note that the term 'universe'
is defined as everything that physically exists: the entirety of
space and time, all forms of matter, energy and momentum, and the
physical laws and constants
that govern them. However, the term 'universe'
may also be used in slightly different contextual senses, denoting
concepts such as the
cosmos, the
world,
and
nature."
