Chemistry in Everyday Life

August 06, 2000

Chemists are not just scientists wearing white coats in laboratories. From such simple tasks as taking vitamins and baking bread to fueling automobiles and fertilizing plants, every person alive works with chemicals and chemical reactions daily, and is in fact a walking laboratory of chemicals in action. Learn how chemistry can help you understand how the world works and explore the many ways chemistry enhances our lives through these direct links on The Times Launch Point Web site: http://www.latimes.com/launchpoint
