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.

Lavoisier made many fundamental contributions to the science of chemistry. Following his work, chemistry acquired a strict, quantitative nature, allowing reliable predictions to be made. The revolution in chemistry which he brought about was a result of a conscious effort to fit all experiments into the framework of a single theory. He ...
The experiments of Antoine Lavoisier (1743–1794), a French chemist regarded as the founder of modern chemistry, were among the first to be truly quantitative. Lavoisier showed that although matter changes its state in a chemical reaction , the quantity of matter is the same at the end as at the beginning of every chemical reaction.
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
The subsequent Age of Enlightenment saw the concept of a scientific revolution emerge in the 18th-century work of Jean Sylvain Bailly, who described a two-stage process of sweeping away the old and establishing the new. [10] There continues to be scholarly engagement regarding the boundaries of the Scientific Revolution and its chronology.

The ground-observed pitch was higher than that played when the train was approaching then lower than that played as the train passed and moved away, demonstrating the Doppler effect. Foucault pendulum (1851): Léon Foucault's creates a pendulum to demonstrate the Coriolis effect and the rotation of the Earth.
