Some laws of phycics have been discovered in ancient times. There are complex physical formulas. Atoms and molecules are an important part of this hard science. Light and electricity work by the laws of physics.
Astronauts must know physics for their work. Ordinary people also should know that science. For example, water is a good conductor of electricity. Electrical items can not be touched by wet hands.
Famous scientists who studied physics: Aristotle, Isaac Newton, Albert Einstein. Today scientists study this science too.
Perhaps physics is more difficult than mathematics. If math is necessary to understand, for physics than physics is more difficult. There is a common subject on physics-chemestry. This science also has complicated formulas.
It was an essay about one of the most complex subjects. Next time will be another.
