Antoine Lavoisier publishes Traité Élémentaire de Chimie, the first modern chemistry textbook. It is a complete survey of (at that time) modern chemistry, including the first concise definition of the law of conservation of mass, and thus also represents the founding of the discipline of stoichiometry or quantitative chemical analysis.

Tanks : developed at the same time (1915–1916) in France and in Great Britain. France was the second country to use tanks on the battlefield (after Great Britain). in 1916, the first practical light tank, the Renault FT with the first full 360° rotation turret became, for armour historian Steven Zaloga "the world's first modern tank".

France carried out its first test of an atomic bomb in Algeria in 1960 [7] and some operational French nuclear weapons became available in 1964. Then, France executed its first test of the much more powerful hydrogen bomb over its South Pacific Ocean test range in 1968; this first hydrogen bomb was dropped from a strategic bomber .

The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature.
Lavoisier subsequently discovered and named oxygen, described its role in animal respiration [90] and the calcination of metals exposed to air (1774–1778). In 1783, Lavoisier found that water was a compound of oxygen and hydrogen. [91] Lavoisier's years of experimentation formed a body of work that contested phlogiston theory.
The oldest message in a bottle ever found was 131 years and 223 days old when it was discovered, Guinness World Records said in a statement. Australians Tonya and Kym Illman found the message on ...
These rays, which he discovered but were later called cathode rays by Eugen Goldstein, produced a fluorescence when they hit a tube's glass walls and, when interrupted by a solid object, cast a shadow. 1869: William Crookes: Invented the Crookes tube. 1873: Willoughby Smith: Discovered the photoelectric effect in metals not in solution (i.e ...
