The first paper explained the photoelectric effect, which established the energy of the light quanta =, and was the only specific discovery mentioned in the citation awarding Einstein the 1921 Nobel Prize in Physics. [3] The second paper explained Brownian motion, which established the Einstein relation = and compelled physicists to accept the ...
Grade 9 subjects include Danish, English, Christian studies, history, social studies, mathematics, geography, biology, physics/chemistry and German and French as electives. [11] Students must sit compulsory school-leaving exams at the end of grade 9, and must also complete a mandatory project assignment during the year.
Physical Review Letters (PRL), established in 1958, is a peer-reviewed, scientific journal that is published 52 times per year by the American Physical Society.The journal is considered one of the most prestigious in the field of physics.
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.

Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
The Feynman Lectures on Physics is a physics textbook based on a great number of lectures by Richard Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". [1] The lectures were presented before undergraduate students at the California Institute of Technology (Caltech), during 1961–1964.
[9]: 28 Newton's original formula was: where the symbol means "is proportional to". To make this into an equal-sided formula or equation, there needed to be a multiplying factor or constant that would give the correct force of gravity no matter the value of the masses or distance between them (the gravitational constant).
