In quantum mechanics, the Pauli exclusion principle states that two or more identical particles with half-integer spins (i.e. fermions) cannot occupy the same quantum state within a quantum system simultaneously.- Quantum mechanics (Wikipedia)
Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.
- Alberta (Wikipedia)
Alberta (/ælˈbɜːrtə/ al-BUR-tə) is one of the thirteen provinces and territories of Canada. It is a part of Western Canada and is one of the three prairie provinces. Alberta borders British Columbia to the west, Saskatchewan to the east, the Northwest Territories to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada, with Saskatchewan being the other. The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds.
