Introduction:
Understanding of
being and time has always been interesting and
difficult for
mankind. Generally, there are three approaches
of religion, philosophy and science to being and
time. In this essay, I have reviewed physical
being and time, because everything in nature is
a physical entity. The question is what
relationship is between being and time and
whether in physics, being and time are
separable? In this essay, I have answered these
questions.
In the early days;
physics was a part of the philosophy. Before
Newton, physics was descriptive and analytic,
and physicists had not used mathematics yet, so
physics was closer to philosophy than science.
For this reason, Newton had named his book
"Mathematical Principles of Natural Philosophy".
Still we are using
philosophical concepts in the physics. One of
these concepts is phenomenon. According to Kant,
it is vital always to distinguish between the
distinct realms of phenomena and noumena.
Phenomena are the appearances, which constitute
our experience; noumena are the (presumed)
things themselves, which constitute reality.
Phenomenon of a
physical event can be different for different
observers. Even the fact of a physical event can
be something different from the phenomenon of
all observers. For example, thousands years
everybody thought that the earth is the center
of the universe, sun and the planets orbit
around the Earth. The appearance of the solar
system in the minds of the people is an Earth
central system. Another phenomenon that is on
everyone's mind at the time it was created, was
that each object must be connected to a physical
object or placed on it. The question was: Where
is the earth standing? That's why some people
thought the Earth was on turtle. For example;
the Ptolemaic Model was based on common
phenomena that earth was the center of the
universe. But Copernicus system was based on
himself phenomena*.
We are not seeing the
world out of it. We are a small part of the
world that we live in. Also, no picture covers
all the landscape, the physical events are not
in our minds, and we will process our personal
phenomena in mind that usually are far from the
reality.
We describe a
personal phenomenon, it will bring judgment and
the others are compared with the phenomenon
itself. In discussion, a common phenomenon will
be created that is closer to reality. The
history of science shows that even a common
human phenomenon isn�t all reality. Physicists
in order to make the joint phenomenon close
together and prevent dispersion of votes and
results used mathematical models.
Therefore physicists
used mathematics to describe reality. Kelvin
said: "When you can measure what you are
speaking about, and express it in numbers, you
know something about it".
Scientific theories
do not show the laws of nature, but are our
understanding of physical phenomena to explain
the nature and closeness of the common phenomena
to the dominating rules of nature. So no theory
is perfect, even if expressed with mathematical
formulas.
* Ptolemy's model
(left side) was based on general common
phenomenon (opinion) that was thought earth was
the center of universe. But Copernicus's model
(right side) was based on his own personal
phenomenon (opinion), this is why the majority
of people opposed it.
