The name "Thomas Edison" makes people think of the first incandescent light bulb or the phonograph machine. Many don't realize that he also created one of the earliest motion picture cameras. This American businessman and inventor was a renowned scientist whose name appears on 1,093 US patents.

Everyone’s favorite Mythbuster, Adam Savage, once said: “the difference between screwing around and science is writing it down!” So true, Adam, so true. As long as you record your observations, you’re a scientist. Scientists gather knowledge, make observations, write them down, and test their theories. This process is known as the scientific method.

There are three main branches of science: physics, chemistry, and biology. These sciences combine with other fields to make specializations. For example, if you wanted to be a doctor, you would study human biology and organic chemistry. If you wanted to be an astronomer, you would study astronomy and astrophysics.

Those that study the sciences will tell you how closely related math, science, and engineering are. The acronym, STEM (Science, Technology, Engineering, and Mathematics), refers to the close relationship between these fields. People in STEM industries help to shape our understanding of the world. Without STEM, our quality of life would be poor. Not only would we be without cell phones and computers, but we also wouldn’t have vaccines and surgery. At this point in history, it is hard to imagine what our lives would look like without it.
