Contributions and Discoveries

__MATRIX MECHANICS__

- one of the first and most used formulations of quantum mechanics, discovered by Heisenberg in 1925

-- quantum mechanics is the type of mathematical physics where atomic and subatomic systems and their interaction with radiation are measured in terms of observable quantities; energy, momentum, position, and angular momentum.

- one problem with matrix mechanics is that it's abstract and difficult to visualize, so many scientists preferred *wave mechanics*, discovered by *Erwin Schrödinger*, instead.

__The UNCERTAINTY PRINCIPLE__

- discovered by Heisenberg in 1927

-- it's a formulation explaining that when wavelengths of light are shone through a particle (this is done in order to be able to observe a particles measurable/observable quantities;energy, momentum, positions, and angular momentum), it disables you to accurately measure a particle's position because it's being hit with light. That's why it's called the 'Uncertainty' principle!

- It basically means that when you try to measure one observable quantity in a particle, the more accurate you get to one measurement, the less accurate you get from another.
