Did you know?

Synthesize is a very common word in chemistry, since chemists are constantly synthesizing new compounds—that is, synthetic compounds—including drugs and industrial chemicals. It's also often used when talking about writing; nonfiction writers must often synthesize large amounts of material from many sources to produce a book—which represents a synthesis of the important materials. An electronic synthesizercreates new sounds (which may imitate the sounds of acoustic instruments) by generating different basic tones and then manipulating and merging them together with others.
