Beyond the Atom: How Modern Physics Powers the 21st Century

Theory of Relativity

However, there is a catch. Einstein’s tells us that time is not absolute.

• Cancer treatment: Proton therapy (hadron therapy) uses particle accelerators—descendants of quantum mechanics—to shoot protons directly at tumors. Because protons deposit most of their energy at a specific depth (the Bragg peak), they destroy cancer cells without damaging overlying skin or organs.

In 1917, Einstein theorized "Stimulated Emission"—the idea that you could nudge atoms to spit out light in a synchronized beam. It took 40 years to actually build one. The Application: Applications Of Modern Physics
