The Sinclair Scientificcalculator was a 12-function, pocket-sized calculator, selling for about $100. It was introduced in late 1974 and sold in both kit and assembled forms.
Power was supplied by four AAA sized alkaline cells. A common failure mode of these calculators was breakage of the battery contacts, but Sinclair was quick to respond by refurbishing any calculator with this problem for free (although you did have to pay the shipping to them).
SINCLAIR, GEORGE, a well-known mathematical writer, was professor of philosophy in the university of Glasgow in the latter part of the seventeenth century.
The self-complacency of Sinclair, and his presbyterian principles provoked the celebrated James Gregory, then a professor at St Andrews, to attack his Hydrostatics in a pamphlet published with the quaint title of the "Art of Weighing Vanity," and under the thin disguise of Patrick Mather, archbeadle of the university of St Andrews.
Sinclair was among the first in Britain who attempted to measure the heights of mountains by the barometer.
Sinclair's passion for and thorough knowledge of country music shone through his sarcastic wit and casual demeanor, particularly in the insightful, respectful interviews he conducted with the many local and national country and bluegrass musicians who visited WHRB's studios.
Sinclair was born in Sabattus, Maine, on Nov. 4, 1940, to Roy and Thoris Sinclair.
Sinclair studied French at Harvard and pursued graduate studies in linguistics at the University of North Carolina, where Joiner was studying anthropology.
