Science Buddies: "Ask an Expert"

I am doing a project on physics for school. Can someone please tell me how many different types of physicists there are?
Thank you

HI azaral,

Physicists can specialize in a number of different areas. Some of these include astrophysics (galaxies, stars, etc), particle physics (quantum mechanics, fundamental building blocks of matter), acoustics (sound), electromagnetism (magnets and electricity), and thermodynamics (energy and entropy in processes). These are just a few of the different subfields in physics.
