known as natural philosophy.
Physics occupies special place among other sciences because it is
the science about the most general laws of nature.
The role of mathematics in physics is very important. Physics as

quantitative science rapidly became and has remained mathematical
science. The laws of physics are typically expressed in the form of
mathematical expression; as such, they are the same for physicists all

over the world. Thus mathematics provides universal language for
physics and means of strict, logical reasoning which is difficult to
activate in any other way.
Surely it's not necessary to convince anybody that today computers

change the way and the manner of our perception of the physical world.
The question: "How can we formulate this problem on a computer?" has
changed our understanding of old problems and allows us to consider the

new ones more effectively.
Now, it is impossible to imagine contemporary physics without
computers. Computers as parts of experimental equipment are used for

analysis of experimental data, for theoretical calculations, etc.
The special field is mathematical modeling of physical processes
and phenomena.Physics is the basis of technology and technical progress.

Over the last three centuries the development of technology has
been closely connected with the development of physics that foresaw and
scientifically grounded new fields in technology. In the XXth century this
connection becomes more indissoluble.

Needs of society initiated the development of many branches of
physics.
All branches of different sciences have at least one thing in common

— measurement. None of the processes or ideas can be described fully
until it can be described mathematically, i.e. until it can be measured.
Description that does not involve measurement and hence does
not involve mathematics is said to be qualitative. On the other hand,

when description is expressed in mathematical terms, it is said to be
quantitative.
Quantitative formulation of physical laws is possible only as the

result of measurement.
Measurement is the process of comparison of physical value with
another one, which is homogeneous with it and is adopted as the unit of

measurement.
As the result of measurement the quantitative meaning of the value
