Subdomains of physics

you will often see, nowadays various professors calling themselves “professor of quantum mechanics” … back in the day they used some titles as “professor of string theory” with the same unjustified pride. The question appearing is: are the various fields of physics indeed so separated? Is overspecialization indeed a problem so that someone from another field would be completely incapable of understanding the depths of a subdomain he was not specifically “trained” into it?

The answer to this question is certainly NO! There are no subdomains of physics especially complicated or demanding knowledge that is so radically different from other fields. There is essentially no domain of physics someone couldn’t become an expert in, if working for 2 months maximally on that field.

So, why the complaints? Why the epaulets of declaring oneself “professor of quantum mechanics”? Why then? It is a popular subject! Some time ago it was String Theory, now it is “Quantum Foundations”… They do not differ majorly from other kind of physics… once a person has a certain ease with general physics and some mathematics one can easily learn any subfield of physics in less than, say 2 months… variations accepted…

One thought on “Subdomains of physics

  1. The next best question would be: are there areas of mathematics that bring in ideas never explored in physics? Is the mathematics of physics done now perfectly consistent? Does it miss some aspects that would appear obvious if one looked at physics in general from the perspective of another mathematical field than just what was done until now? Certainly YES!
