This book is not a physics textbook.
There are no calculations, no formulas.
It gives a simple and understandable
explanation of physical laws and
examples of how these laws work
in the daily life of each of us.
FROM THE AUTHOR
This book is not a physics textbook. In it you
will You won't find strict definitions, formulas
or complicated calculations. Nor is there a
clear sequence: you don't have to read from
the beginning,but from any chapter, and then
jump to another. I don't think you can learn
anything from it. But that's not what it's all
about.
Usually after passing a high school physics
course, only scraps of laws and formulas
remain in one's head. A little better
remembered are the visual experiments that
are still sometimes shown in schools. But in
general, most graduates are left with the
feeling that physics is, on the one hand,
something complex, where you have to solve
problems and strain your head hard, and on the
other, something abstract, not applicable to
everyday life. And few will observe and think
about why this or that phenomenon happens, or
what physical law is behind it.
Why, for example, does food in a microwave
heats up, but a plastic container does not?
How can a bridge support the weight of a huge
train without collapsing? Where is the current
in the wires? Why can't you stand next to
an oncoming train and how is it to do with
airplanes?
We would like readers to have a flash of
awareness, maybe even more than one,
physics is not about bearded scientists in
white coats. Physics is all around us every
minute of every day, we live in a world of
physical laws, and there's no way around it.
You can use them, you can study them, you
can admire them! If someone finds something
in this book inaccurate or misunderstood,
and picks up a school textbook or a Landau -
Lifshitz course, or opens a popular lecture
on the Internet, we will consider our mission
accomplished.
