🧿 New Form of Matter 🟠

"Measurements on a superconducting material show an abrupt transition between a normal metal and a "strange" metal. The really strange thing, however, is that this abruptness disappears when the temperature falls.

The moral of the story, says Zaanen, is that the origin of superconductivity itself is increasingly a side issue. "After thirty years, evidence is mounting that high Tc -superconductivity is pointing toward a radically New Form of Matter, which is governed by the consequences of Quantum Entanglement in the macroscopic world."

🧿 Molecular Definition of Pressure 🌞

🧿 Molecular Definition of Pressure 🌞From the kinetic theory of gases, a gas is composed of a large number of molecules that are very small relative to the distance between molecules. The molecules of a gas are in constant, random motion and frequently collide with each other and with the walls of any container. The molecules possess the physical properties of mass, momentum, and energy. The momentum of a single molecule is the product of its mass and velocity, while the kinetic energy is one half the mass times the square of the velocity. As the gas molecules collide with the walls of a container, as shown on the left of the figure, the molecules impart momentum to the walls, producing a force perpendicular to the wall. The sum of the forces of all the molecules striking the wall divided by the area of the wall is defined to be the pressure. The pressure of a gas is then a measure of the average linear momentum of the moving molecules of a gas. The pressure acts perpendicular (norma…
