Collision theory is a principle of chemistry used to predict the rates of chemical reactions. It states that when suitable particles of the reactant hit each other with the correct orientation, only a certain amount of collisions result in a perceptible or notable change; these successful changes are called successful collisions.
1964 – CP violation discovered by James Cronin and Val Fitch. 1965 – Arno Penzias and Robert Wilson: Cosmic Microwave Background (CMB) discovered; 1967 – Unification of weak interaction and electromagnetism (electroweak theory) 1967 – Solar neutrino problem found; 1967 – Pulsars (rotating neutron stars) discovered
The pivotal question then, was how to unify Maxwell's wave theory of light with its experimentally observed particle nature. The answer to this question occupied Albert Einstein for the rest of his life, [57] and was solved in quantum electrodynamics and its successor, the Standard Model. (See § Quantum field theory and § As a gauge boson ...
He also independently discovered the law of reflection, and his essay on optics was the first published mention of this law. [34] Christiaan Huygens (1629–1695) wrote several works in the area of optics.
1746 – Leonhard Euler develops the wave theory of light refraction and dispersion; 1747 – William Watson, while experimenting with a Leyden jar, observes that a discharge of static electricity causes electric current to flow and develops the concept of an electrical potential .
The new park is dedicated in honor of Holmdel resident and Nobel Laureate Dr. Robert Woodrow Wilson, who discovered the evidence for the Big Bang Theory of evolution at the site in 1964.
This theory came to dominate the conceptions of light in the eighteenth century, displacing the previously prominent vibration theories, where light was viewed as "pressure" of the medium between the source and the receiver, first championed by René Descartes, and later in a more refined form by Christiaan Huygens.
