Physics is the most fundamental of the sciences. It is concerned with the most basic building blocks of all things - from ants to antennas, from quarks to quasars. The study of physics means trying to find out what the universe is made of, and how these things move and interact with each other. So in one sense, all the other sciences are built on the knowledge gained through the study of physics. Physics is beautiful.
Physicists love simplicity.
They are constantly striving to find the most fundamental ideas that can be used to describe even the most complex of phenomena. For example Newton found that only a very small number of concepts could be used to describe just about all of the mechanical world - from steam engines to the motion of the planets. Physics teaches you to think. This might seem like a strange statement. The study of all subjects teach you to think.
