Albert Einstein is perhaps most famous for introducing the world to the equation E=mc2. In essence, he discovered that energy and mass are interchangeable, setting the stage for nuclear power—and atomic weapons.

Albert Einstein received a patent for a camera which could automatically determine the proper aperture and exposure to take a photograph. Einstein employed an “electric eye”, or photoelectric sensor, in his invention, which was one of his approximately 50 patents.

Shortly after Einstein’s death in 1955, Harvey removed and weighed the brain at 1230g.

Our current model of the atom can be broken down into three constituents parts – protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge.

At one level, the equation is devastatingly simple. It says that the energy (E) in a system (an atom, a person, the solar system) is equal to its total mass (m) multiplied by the square of the speed of light (c, equal to 186,000 miles per second).

Our existence, as well as our ability to touch and interact with the universe around us, is governed by the collisions of atoms and molecules. The constant jostling and vibrating of these particles give us heat, light, and life.

An atom. Protons are colored red with a “+” charge. Neutrons are green with no charge. Electrons are blue with a “-” charge.

By mass, about 96 percent of our bodies are made of four key elements: oxygen (65 percent), carbon (18.5 percent), hydrogen (9.5 percent) and nitrogen (3.3 percent). These elements do not give color to fireworks, but they are found in our body’s most abundant and important molecules, including water, proteins and DNA.
