Why do we believe in electrons, but not in fairies?
by Benjamin Kuipers
No one has directly observed either electrons or fairies. Both of them are theoretical constructs, useful to explain observations that might be difficult to explain otherwise. The “theory of fairies” can actually explain more things than the “theory of electrons”. So why do we believe in electrons, but not in fairies?
Is the issue a political one, where the “electron” fans got the upper hand in the nineteenth century, so by the twentieth century the “fairy” fans were a scorned and persecuted minority? Or, have we proved for sure that fairies don’t exist?
