The field of chemistry requires the use of computers in a multitude of ways. Primarily, computers are useful for storing vast amounts of data for the researcher or student to use. From facts about the periodic table to displaying 3-D models of...

Chemistry is the science that studies why materials have their characteristic properties, how these particular qualities relate to their simplest structure, and how these properties can be modified or changed. The term chemistry is derived from the...

Chemistry deals with the study of the properties and reactions of atoms and molecules. In particular, chemistry deals with reaction processes and the energy transition. Major divisions of chemistry include inorganic chemistry, organic chemistry...

Chemistry is the science that studies the properties and composition of matter, the changes in composition and structure that occur, and the energy phenomena accompanying these changes. The term chemistry is a shortened form of the word alchemy....

Chemistry (from Egyptian kēme (chem), meaning "earth"[1]) is the science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions.[2] Historically, modern chemistry evolved out...

Stephen Craig, Al Nichols, and Nagarajan Vasumathi, Dept. of Physical and Earth Sciences, Jacksonville State Univ., Jacksonville, AL 36265. Starting with ethyl 5,7-dichloro-4-{[(4-methylphenyl)sulfonyl]amino}quinoline-2-carboxylate prepared by a previously reported...

The relationship between chemistry and biology is succinctly embodied in the often-cited statement "cells obey the laws of chemistry." In this context, it is also relevant to reflect on the opening lines of the famous paper by Watson and Crick: "We wish to...

We think the biological clock is unique to women and that men hear it second-hand, via gentle prodding or violent arm-twisting—and some, due to the volume on their televisions, never hear it at all. Is it true that most guys are seeking another decade of...

Terry Collins sounds like the world's most dour pessimist. The Carnegie Mellon University chemistry professor paints a bleak picture of the Earth's future, a planet damaged by global warming and ravaged by toxins, with a population sickened by poisonous chemicals."We are practicing time-limited technologies that...
