## Natural Units

I’m back! I decided to blog this because it didn’t feel substantial enough to have notes on its own and I couldn’t find a proper place for it elsewhere so here I am.

Today, I wanted to discuss natural units i.e. the system under which $c=1$, $\hbar=1$, etc. It became apparent to me that many believe such a system is the result of convenience or laziness but this could not be further from the truth! There are some deep physical insights associated with such a system which I think never weaves its way into standard curriculum and one which I would like to lay down here. First, we must understand how we work with physical units.
