Document Summary
The beginnings of quantum mechanics: until the beginning of the 20th century it was believed that all physical phenomena were deterministic: if you know the present state, you can calculate the future state precisely, physicists discovered that, for sub atomic particles, the present condition does not determine the future condition. M. dirac, and erwin schr dinger: quantum mechanics (the physics of very small particles) forms the foundation of chemistry explaining the periodic table and the behavior of the elements in chemical bonding as well as providing the practical basis for lasers, computers, and countless other applications. Node is the point on a wave where the value = 0; change in sign: amplitude is the vertical height of a crest (= depth of a trough). Distance from node to crest or node to trough: wavelength ( ) is the distance between adjacent crests (or in general between given period of time. any two adjacent analogous points).
