I had similar feelings when I read Bill Bryson's 'A Short History of Nearly Everything' especially since he always pointed out how little we know and how incredibly huge or small things are. Some things are beyond imagination, in a very literal sense. It kind of makes you dizzy.

I read about quantum physics sometimes at work when I'm trying to "clear my mind before starting a new project" (aka: procrastinating).

Maybe I should look into lighter reading material? Quantum physics hurts my brain. Plus, I don't like numbers.
