General Science: Expert Guides and Resources

Whether you're talking about evolution — or any other element of science — you should understand the process of scientific investigation, which proves or disproves a scientific theory. Take a look at a chart of our hominid ancestors as discovered through fossil records, and learn some key terms to grasp the course of evolution.

Albert Einstein revolutionized science with his famous writings on relativity and quantum physics. But Einstein was more than a scientist — he was also a complex and well-respected man and an NAACP member who called racism America's "worst disease."

How do the scientists know what they know? When it comes to gathering information, scientists usually rely on the scientific method. The scientific method is a plan that is followed in performing a scientific experiment and writing up the results. It is not a set of instructions for just one experiment, nor was it designed by just one person.

When Einstein began his research as an amateur scientist, there were two major problems: Light was known to be a wave but had to be considered as made up of lumps — not waves — to explain the ultraviolet catastrophe (the observation that hot objects emit less ultraviolet light and more light of other colors).In mechanics, the results of experiments are identical in motion or at rest (all motion is relative, and there is no absolute motion).

Einstein obviously had a tremendous influence on the scientific community and the entire world. Einstein enjoyed people's company and learned a great deal from those around him – including the two women whom he married over the course of his life. First wife, Mileva Mileva Maric was the only female physics major at the Polytechnic in Zurich, where Einstein went to college.

For those of us who keep our eyes fixed to the heavens, Einstein's theory of special relativity has thrilling implications. Namely, the relativity of time and space allows for the possibility of human interstellar travel. The nearest stars to Earth, the binary stars Proxima and Alpha Centauri, are about four light-years away.

The energy of a nuclear bomb comes from inside the nucleus of the atom. Mass is converted into energy according to E = mc2. This energy is the binding energy of the nucleus, the glue that keeps the nucleus of the atom together. Radiating particles In some cases, the nuclear force is not able to keep a nucleus all together, and the nucleus loses some of its particles.

Boy, put biology, geology, and chemistry together, and you get biogeochemical! When you talk about the "circle of life," the circle to which you are referring is a biogeochemical cycle. The plants and animals that live and then die are the bio part; the earth that they decompose into comprises the geo part; and the process by which organic matter returns to the chemical elements in the earth is explained by the chemical part.
