Are electrons, neutrons and protons visible?

I would think the physics since everything is based on it, even the mind. physics> chem> biology. Evolution of the universe and all.

Don't get wrong I like physics and I'm especially fascinated by lasers, electronics and semiconductor devices and cryogenics.

 

Oops I forgot to add spintronics which is a new field which could produce new and faster computers. Spintronics, semiconductors, nonvolatile memories, quantum computers are all based on nothing else but physics.

 

Lasers also have many applications and are used in industry and materials processing. Lasers are used for cutting, welding, marking and for measurements.
