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.

France has a long history of innovation and scientific discovery, contributing to various fields such as physics, mathematics, engineering, medicine, and the arts. [1] French inventors and scientists have pioneered breakthroughs that shaped the modern world, from the development of photography and the metric system to advancements in aviation ...
Bernard Courtois (French pronunciation: [bɛʁnaʁ kuʁtwa]), also spelled Barnard Courtois, (8 February 1777 – 27 September 1838) [1] was a French chemist credited with first isolating iodine, making early photography possible.

A 100,000-year-old ochre-processing workshop was found at Blombos Cave in South Africa. It indicates that early humans had an elementary knowledge of mineral processing. Paintings drawn by early humans consisting of early humans mixing animal blood with other liquids found on cave walls also indicate a small knowledge of chemistry. [3] [4]
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 ...
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.
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.
