Electromagnetism - DAMTP
www.damtp.cam.ac.ukAt the atomic scale, electromagnetism (admittedly in conjunction with some basic quantum e ects) governs the interactions between atoms and molecules. It is the force that underlies the periodic table of elements, giving rise to all of chemistry and, through this, much of biology. It is the force which binds atoms together into solids and liquids.

It is clear from this equation that the wavefunction must be complex: if it were real, the right-hand side of (1.2) would be real while the left-hand side would be imaginary, due to the explicit factor of i. ...
