In 1663 (or, according to some sources, in 1661) the same demonstration was given in Berlin before Frederick William, Elector of Brandenburg with twenty-four horses. 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 ...
In modern physics, the double-slit experiment demonstrates that light and matter can exhibit behavior of both classical particles and classical waves.This type of experiment was first performed by Thomas Young in 1801, as a demonstration of the wave behavior of visible light. [1]
Thomson's experiments with cathode rays (1897): J. J. Thomson's cathode ray tube experiments (discovers the electron and its negative charge). Eötvös experiment (1909): Loránd Eötvös publishes the result of the second series of experiments, clearly demonstrating that inertial and gravitational mass are one and the same.
Public scientific demonstrations were a common occurrence in the Age of Enlightenment, and have long been a feature of the British Royal Institution Christmas Lectures, which date back to 1825. In the television era, scientific demonstrations have featured in science-related entertainment shows such as MythBusters and Brainiac: Science Abuse .
Benjamin Franklin's experiment with bells and a lightning rod has remained a popular example of electric phenomena in modern times. The experiment has been adapted and updated, and is now commonly used in classrooms and demonstrations to illustrate a variety of concepts related to electricity.
Tyndall's bar breaker is a physical demonstration experiment to demonstrate the forces created by thermal expansion and shrinkage. It was demonstrated 1867 by the Irish scientist John Tyndall in his Christmas lectures for a "juvenile auditory".
