1774 – Charles Mason: Conducts an experiment near the Scottish mountain of Schiehallion that attempts to measure the mean density of the Earth for the first time. Known as the Schiehallion experiment. 1796 – Edward Jenner: tests the first vaccine. 1798 – Henry Cavendish: Torsion bar experiment to measure Newton's gravitational constant.
The experiment became a popular way to illustrate the principles of air pressure, and many smaller copies of the hemispheres were made, and are used to this day in science classes. Reenactments of von Guericke's experiment of 1654 are performed in locations around the world by the Otto von Guericke Society.
Benjamin Libet's experiment on free will shows that a readiness potential appears before the notion of doing the task enters conscious experience, sparking debate about the illusory nature of free will yet again. (1983) Vilayanur S. Ramachandran's experiment on phantom limbs with the Mirror Box throw light on the nature of 'learned paralysis ...
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.
The history of science is often seen as a linear story of progress [27] but historians have come to see the story as more complex. [ 28 ] [ 29 ] [ 30 ] Alfred Edward Taylor has characterised lean periods in the advance of scientific discovery as "periodical bankruptcies of science".
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.

The historiography of science or the historiography of the history of science is the study of the history and methodology of the sub-discipline of history, known as the history of science, including its disciplinary aspects and practices (methods, theories, schools) and the study of its own historical development ("History of History of Science", i.e., the history of the discipline called ...
