Inventor of the instrument which bears his name, b. at Ornans, Franche-Comte, c. 1580; d. there, 14 Sept., 1637. His father was his teacher in science. He became captain and castellan, for the King of Spain, of the castle at Ornans, and councillor and director general of moneys in the County of Burgundy. At Brussels, 1631, he published and dedicated to the Infanta, the treatise "La construction, l'usage, et les propriétés du quadrant nouveau de mathématiques", describing the ingenious device on which his fame now rests. To a quadrant with a primary scale in half degrees Vernier proposed to attach a movable sector, thirty-one half degrees in length but divided into thirty equal parts (each part consisting then of a half degree plus one minute). In measuring an angle, minutes could be easily reckoned by noticing which division line of the sector coincided with a division line of the quadrant. Christopher Clavius had mentioned the idea but had not proposed to attach permanently the scale to the alidade. The name vernier , now commonly applied to a small movable scale attached to a sextant, barometer, or other graduated instrument, was given by Lalande who showed that the previous name nonius, after Peter Nunez, belonged more properly to a different contrivance.

Catholic Encyclopedia

Designed to present its readers with the full body of Catholic teaching, the Encyclopedia contains not only precise statements of what the Church has defined, but also an impartial record of different views of acknowledged authority on all disputed questions, national, political or factional. In the determination of the truth the most recent and acknowledged scientific methods are employed, and the results of the latest research in theology, philosophy, history, apologetics, archaeology, and other sciences are given careful consideration.

No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
