- Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed.
- When an ambitious young inventor named Charles E Kettering set up a small laboratory in a Dayton, Ohio, barn in 1909, he laid the foundation for what was to become the automotive industry’s first research laboratory.

- Archaebacteria, simple organisms that resemble ordinary bacteria in that they lack a well-formed nucleus and can therefore be characterized as procaryotes in the classification of living organisms. Their biochemistry differs in important ways from that of other bacteria, however, and some biologists place them in a kingdom of their own.
- In recent years, scholarly communication has virtually exploded into the on-line electronic world. This has brought a number of demonstrable benefits to the scholarly communication process as well as highlighting a number of inefficiencies and obstacles to the full deployment of information technology.

- [ABSTRACT]AbstractIn the late 1940s, few Americans had any idea what the long-term effects of nuclear radiation might be, and their government wasn’t telling them. Dr. Linus Pauling had already won renown for his application of modern physics to the problems of chemistry when he took on the unpopular task of informing the public about the dangers of nuclear weapons.
- After graduating from high school he taught in country schools in Indiana and Montana for three years. In 1914 he entered Montana State University where he majored in zoology and minored in chemistry. He received a Bachelor of Science degree in 1917 and worked as an industrial chemist in Philadelphia until the end of World War I.
- Thomas A. Edison earned his reputation as one of America’s greatest inventors and heroes.
