The Subject is Physics

In the last hundred years, research in pure science has revealed much about how the universe works. In addition to advancing understanding of the nature of the universe, physical research has resulted in unexpected benefits. Linear electron accelerators treat millions of cancer victims worldwide every year. Medical diagnoses are aided with CAT (Computer-Aided Tomography) scans and MRI (Magnetic Resonance Imaging) technology resulted from particle physics research. Lasers are used not only in medicine, but also in areas such as information storage for CD-ROM discs and players and hologram art.

Physics ranges from the microscopic, such as the top quark, to the macroscopic, the universe. The Internet has some excellent tutorials, demonstrations, and online textbooks.
