 Isaac Newton (1643 – 1727) was an English physicist, mathematician, astronomer, natural philosopher,
alchemist and theologian. His Principia Mathematica, is widely considered to be the most influential book in the history of science. In this work, Newton described universal gravitation and the three laws of motion, laying the groundwork for classical mechanics, which dominated the scientific view of the physical universe for the next three centuries.

Claims of cell phones causing brain cancer are becoming common. An examination of the basic properties
of electromagnetic radiation and suntanning shows that this cannot be true.
We examine what a scientific theory is and how it differs from the usual English meaning of the word.
Gain some practice with the Laws of Physics by applying them to some puzzles and movie plots.
The physics behind the interaction of radiation and matter tells us that cell phones cannot
cause cancer. So why does the idea persist? We dig into the history of radiation and cancer
to find out why.
The journal Science is reporting that two studies claiming that radiation from cell
phones can cause DNA damage are fraudulent.
