For clarity’s sake it is essential that the preceding article by Heisenberg be rectified immediately.[ 2 ] These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
Electric fields and magnetic fields exert a manifest influence, or effect, on the energy levels of an atom. These effects, revealed for example by the splitting of spectral lines, are called Stark and Zeeman effects, respectively. The Stark effect (first observed by Johannes Stark in 1913) plays an important role, for example, in theoretical attempts to understand the formation of molecules from atoms. Our interest will be in the Zeeman effect—especially as we consider the notion of “spin,” and spin wave functions in the next chapter, particularly in Section 9.3 there.

Scientists sometimes pretend that what they do is as natural as breathing, and hence they have no philosophies. But Heisenberg, Bohr, Schrodinger, and Einstein all paid attention to theirs, and indeed no scientific discipline in this century has attracted more philosophical comment than quantum physics. 172 Should one not therefore make a compendium of these views, the better to shift truth from error?
