In our daily lives, we believe we touch objects and surfaces, but fundamentally, this isn’t accurate. All matter is composed of atoms, which include electrons. When atoms come close, their electrons repel each other. This fundamental principle of physics means that objects never actually touch. What we perceive as touch is the electromagnetic force produced…
As far as we know, the universe is made up of fundamental particles like electrons and quarks. Everything we see in the universe, including ourselves, is the result of interactions between these particles. Fundamental forces mean interactions of elementary particles. Four fundamental forces have been identified. They are gravitational force, electromagnetic force, weak nuclear force…
We know that an atom is made up of tiny particles called electrons, protons and neutrons. The discovery that protons and neutrons are made up of smaller atoms is crucial in the history of modern physics. The physical model of these is known as the Standard Model of Particle Physics. The standard model states that…
Mole is a word that those who have studied science may have heard at least once. Few people do not think that this is their mole or that they should call it a mole for some reason. The concept of mole was conceived by the scientist Amidio Avogadro. The concept of mole is based on…
