You use dimensional analysis to check if your answer is in the right units. For example, if a question asks you to solve for the energy, but your answer is in kilograms, you made a mistake somewhere.
To do this you break up all the types of units into mass, time, length, electric charge and temperature....

Bell's Theorem and Quantum Entanglement
Bell’s Theorem, introduced in 1964 by John Steward Bell in his paper On the Einstein Podolsky Rosen paradox, deals with the “spooky action at a distance” that is at the heart of so much quantum weirdness. The gist of the theorem is this: if there are local explanations for the results we see due to entanglement then there are a set of inequalities which the outcomes of the...
