It's death anniversary of #LouisVictorPierreRaymonddeBroglie, the man who made groundbreaking contributions to quantum theory
(Scientist of the Day - 19 March)
For his groundbreaking theory (De Broglie hypothesis - his PhD thesis), he won the 1929 Nobel Prize in physics.

Hello all members, we have a new member who is doing his PhD in condensed matter physics (Research area: Quantum magnetism, spintronics). He is studying in university of Nottingham. He is keen to help us in this group and also prepare google (zoom) meetings sometimes (on topics you members opt for).

THE FOUR FUNDAMENTAL FORCES OF NATURE
The concept of the four fundamental forces of nature is a crucial aspect in physics. While frictional force, tension force, normal reaction, and fluid resistance are some of the common forces we have all learned about in lower grade physics, none of them is classified as fundamental forces. Instead, these forces belong to one of the four distinct classes of the fundamental forces. Two of these forces are well-known, while the other two are impossible to perceive with our senses alone.
The first of these forces is the gravitational force, which is the force between any objects with mass. It is the force that governs the movement of planets in orbit, and even the internal structure of massive celestial objects such as stars, planets, and galaxies is a result of the gravitational force. Because of this force, most planets are almost spherical, while asteroids with less mass have irregular shapes.
The second fundamental force is the electromagnetic force, which is a combination of electric and magnetic forces. Collectively, these forces form the electromagnetic force. At one time, scientists believed they were separate types of forces, but Faraday's work unified them into one. This force is responsible for the formation of molecules. Atoms possess a positive, negative, or zero charge, which means they can exert a force on each other if they are brought near to each other. This force turns into intermolecular force once they combine as one: it is the second strongest force out of the four.

Homo naledi had much smaller brains than modern-day humans. Burials and carvings were previously thought to be associated with larger-brained species.

Loop Quantum Gravity (LQG) is a theory of quantum gravity, which aims to merge quantum mechanics and general relativity, incorporating matter of the Standard Model into the framework established for the pure quantum gravity case. It is an attempt to develop a quantum theory of gravity based directly on Einstein's geometric formulation rather than the treatment of gravity as a force.
As a theory LQG postulates that the structure of space and time is composed of finite loops woven into an extremely fine fabric or network. These networks of loops are called spin networks. The evolution of a spin network, or spin foam, has a scale above the order of a Planck length, approximately 10β»Β³β΅ meters, and smaller scales are meaningless. Consequently, not just matter, but space itself, prefers an atomic structure. β¨
