I'm sure there are some quantum physicists who would disagree with this 
statement and would perhaps say that these quantisations occur more by 
virtue of the observer (or way of measurement) ..

In any case, all these tiny events, particles, etc. are nothing more 
than theoretical models which scientists have made up to try to 
understand and predict what's actually going on at such tiny levels.

(Just my personal opinion .. I'm no physicist!)
