The year 1725 in science and technology involved some significant events.

Astronomy

James Bradley first observes stellar aberration.
John Flamsteed's Historia Coelestis Britannica is published posthumously in a version containing Flamsteed's revisions, thanks largely to the efforts of his widow, Margaret, and former assistants Abraham Sharp and Joseph Crosthwaite.

History of science

John Freind (physician) begins publication of The History of Physick, from the time of Galen to the beginning of the 16th century, chiefly with regard to practice, the first comprehensive history of medicine in English.

Mathematics

The binary numeral system is invented by Basile Bouchon.
The construction of a 4x4 Graeco-Latin square is published as a puzzle involving playing cards by Jacques Ozanam in Recreation mathematiques et physiques , vol. IV.
Pierre Varignon's Nouvelle Méchanique ou Statique, published posthumously in Paris, includes recognizable planar dual graphs.

Technology

Stereotype printing, a copying process, is developed by Scottish goldsmith William Ged. The concept later generates the word "stereotyping".
The ocular Harpsichord, or clavecin oculaire, comprising a 6-foot square frame above a normal harpsichord, is invented by the Jesuit mathematician and physicist Father Louis-Bertrand Castel. No illustrations of it remain.

Dru Drury was a British collector of natural history specimens and an entomologist. He received specimens collected from across the world through a network of ship's officers and collectors including Henry Smeathman. His collections were utilized by many entomologists of his time to describe and name new species and he is best known for his book Illustrations of natural history which includes the names and descriptions of many insects, published in parts from 1770 to 1782 with most of the copperplate engravings done by Moses Harris.
