Machines that generated static electricity with a glass disc were popular and widespread in Europe by 1740. [3] In 1745, German cleric Ewald Georg von Kleist and Dutch scientist Pieter van Musschenbroek discovered independently that the electric charge from these machines could be stored in a Leyden jar , named after the city of Leiden in the ...
The Danish physicist Valdemar Poulsen creates the world's first magnetic recording and reproduction, using a 1 mm thick steel wire as a magnetizable carrier. Nikola Tesla publicly demonstrated the first wireless remote control of a model ship. 1899: The dog "Nipper" is used in "His Master's Voice", the trademark for gramophones and records.
This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.
Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.
Rectifiers of this type were used in electric motor power supplies for industry, in electric railways, streetcars, and diesel-electric locomotives. They also found use in static inverter stations and as rectifiers for high-voltage direct current power transmission. Mercury arc rectifiers were invented by Peter Cooper Hewitt in 1902. [90]
1380: Madhava of Sangamagrama discovers the most precise estimate of π in the medieval world through his infinite series, a strict inequality with uncertainty 3e-13. 15th century: Parameshvara discovers a formula for the circumradius of a quadrilateral. [114] 1480: Madhava of Sangamagrama found pi and that it was infinite.
