Modern physics is a branch of physics that developed in the early 20th century and onward or branches greatly influenced by early 20th century physics. Notable branches of modern physics include quantum mechanics, special relativity and general relativity.
Welcome to modern physics essentials (Course intro) Electrons, protons, neutrons, photons - these are the fundamental building blocks of everything you see around us. From the tiniest grains of sand to the biggest stars in our cosmos. But, they defy Newton's laws.

Thermodynamics of the climate system. While the first law of thermodynamics is a well-established principle underlying all models of Earth’s climate system, applications of the second law in climate science are active areas of research.
What Is Modern Physics? Modern physics is a branch of physics that deals with the post-Newtonian concepts in the world of physics. It is based on the two major breakthroughs of the twentieth century: Relativity and Quantum Mechanics. Quantum effects typically involve distances related to atoms.

- The photoelectric effect is a phenomenon where electrons are emitted from the metal surface when the light of sufficient frequency is incident upon...
- Albert Einstein is known as the father of modern physics. He was a 20th-century scientist, who came up with the most important ideas.
- To stay in thermal equilibrium, a black body must emit radiation at the same rate as it absorbs, and so it must also be a good emitter of radiation...
- The blackbody radiation curve for different temperature peaks at a wavelength is inversely proportional to the temperature.
- Davisson-Germer Experiment established the wave nature of electrons.
- Work Function of metal is defined as the minimum energy required by an electron to just escape from the metal surface.

New paradigms of thinking such as relativity and quantum mechanics emerged. This course is the first course in the Understanding Modern Physics series, which covers an introduction to special relativity, general relativity and cosmology.
Jun 21, 2021 · "Modern" physics means physics based on the two major breakthroughs of the early the twentieth century: relativity and quantum mechanics. Physics based on what was known before then (Newton's laws, Maxwell's equations, thermodynamics) is called "classical" physics.
