What is Modern Physics?


Modern physics is a department of physics that offers with post-Newtonian ideas on the planet of physics. It’s based mostly on the 2 main breakthroughs of the 20th century: Relativity and Quantum Mechanics.

Modern Physics is the physics of the 20th century.  The primary constructing blocks, the idea of relativity and quantum mechanics, have been developed early in that century.  Two several types of issues with classical physics turned apparent at the finish of the nineteenth century.  One downside was an inner inconsistency.  The opposite kind of downside arose from measurements that might not be understood utilizing classical physics.

Modern physics typically entails an advanced description of nature by new theories which have been totally different from the classical descriptions and entail components of quantum mechanics and Einsteinian relativity. For example, quantum results usually contain distances associated with atoms. However, relativistic results usually contain velocities in comparison with the velocity of sunshine.

The Father of Mordern Physics

Albert Einstein is called the father of recent physics. He was a Twentieth-century scientist, who got here up with important concepts. One of many vital works of Albert Einstein is the idea of relativity and the well-known equation E=mc2.

He was awarded the Nobel Prize for physics in 1921 for his achievements in theoretical physics, significantly discovering the law of photoelectric impact.
