No one knows who wrote the laws of physics or where they come from. Physics is
about questioning, studying, probing nature. Scientists are motivated by the thrill of
seeing or figuring out something that no one has before.
Science will never be "finished." Every person feels the effects of science in every sphere of life. It is not merely the electric light or the electric fan, the radio or the cinema that displays the power of science in our daily life, but everything we do or is done to us is in some way or another connected with science.
The knowledge generated by science is powerful and reliable. It can be used to devel-
op new technologies, treat diseases, and deal with many other sorts of problems. Science is continually refining and expanding our knowledge of the universe, and as it does, it leads to new questions for future investigation.
Physics is a way of discovering what's in the universe and how those things work today, how they worked in the past, and how they are likely to work in the future.
And what means new cosmos?
What is hidden nature problem?
Who knows future?
Is time travel possible?
