Quantum Physics Quiz

Quantum field theory and quantum mechanics.

Quantum Physics studies how particles behave at levels below the atomic.

At levels below the atomic, Quantum Physics allows for realistic calculations within the microscopic arena.

<p>Derivations from calculations under quantum physics can sometimes appear strange when juxtaposed against workings within the physical arena because the microscopic arena is not discernible under ordinary circumstances.</p> Signup and view all the answers
