I would like to challenge you all to(adsbygoogle = window.adsbygoogle || []).push({}); definequantum mechanics.

An ideal definition should contain only one sentence and should cover all aspect of quantum mechanics. If you cannot construct an ideal definition, you can try with a good but not ideal one which covers most but not all aspects of quantum mechanics, and/or contains more than one sentence.

Here is my try:

Definition 1 (probability amplitude):

Probability amplitude is a complex number the squared absolute value of which is equal to probability.

Definition 2 (quantum mechanics):

Quantum mechanics is a branch of physics which studies probabilities of different measurement outcomes, for systems for which the probability can be most easily calculated from a probability amplitude.
