Energy is the capacity to do work or produce an effect. It is a fundamental concept in physics and plays a central role in various scientific disciplines, including thermodynamics, mechanics, and electromagnetism. Energy can exist in various forms and can be transformed from one form to another, but the total amount of energy in a… Read More

Axon is a type of cell in the nervous system that transmits electrical signals between neurons. These signals are sent from the body to the brain, and then from the brain to other parts of the body. Axons are important for communication between different areas of the nervous system, and they also play a role… Read More

The word “electron” was coined in 1894 by Irish physicist George Johnstone Stoney (1826–1911). He suggested that electrons were components of atoms and proposed the name “corpuscle” for them. In 1897, English physicist J. J. Thomson (1856–1940) discovered electrons in cathode ray experiments and proposed that they were parts of atoms as well. Electrons are… Read More

Electromagnetism is one of the four fundamental forces of nature and the other three are gravity, weak interaction, and strong interaction. It is the force that governs the behavior of electrons and protons, and it is responsible for most of the physical phenomena we see in everyday life. Electromagnetism arises from two basic principles: electricity… Read More

Electricity is the set of physical phenomena associated with the presence and motion of electric charge. Although initially considered a phenomenon separate from magnetism, since the development of Maxwell’s equations, both are recognized as part of a single phenomenon: electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges,… Read More
