- | <note tip> | + | Quantum numbers are what we use to label elementary particles and their values are crucial for the behaviour of particles in experiments. |
- | Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party. | + | |
- | </note> | + | For example, an electron is defined by the following quantum numbers |
- | | + | |
+ | * mass: $9,109 \cdot 10^{-31}$ kg | ||
+ | * spin: $\frac{1}{2}$ | ||
+ | * electric charge: $1,602 \cdot 10^{-19}$ C | ||
+ | * weak charge, called weak isospin: $-\frac{1}{2}$ | ||
+ | * strong charge, called color charge: $0$ | ||
+ | |||
+ | |||
+ | These labels determine how a given elementary particle behaves in experiments. The techincal term for these labels is quantum numbers. | ||
