Dew Point. (Abbrev. DWPT) - A measure of atmospheric moisture. It is the temperature to which air must be cooled in order to reach saturation (assuming air pressure and moisture content are constant). A higher dew point indicates more moisture present in the air. It is sometimes referred to as Dew Point Temperature, and sometimes written as one word (Dewpoint). You can either type in the word you are looking for in the box below or browse by letter.
The story has been told many times around Teal campfires of how the first Teal, then called a Worsley, was designed by IAN FOSTER on the back of several fag packets in the bar of The Pack Horse Inn at Affetside, Bury in 1983.
Historical Background. It is considered by some that the screw thread was invented in about 400BC by Archytas of Tarentum (428 BC - 350 BC). Archytas is sometimes called the founder of mechanics and was a contemporary of Plato. One of the first applications of the screw principle was in presses for the extraction of oils from olives and juice from grapes. The oil presses in Pomeii were worked by the screw principle. Archimedes (287 BC - 212 BC) developed the screw principle and used it to construct devices to raise water.
