There are lots of kinds of radiation. I think most are divided into Particle radiation, and then there's ionizing and non-ionizing radiation. Gamma radiation, gamma bursts that sort of thing are particle, ultraviolet, X-ray are ionizing and then the less powerful like radio waves and heat, electromagnetic are non-ionizing.

How 'bout this, it's really easy. What's the antimatter counterpart to an electron?

Gamma radiation is EM, not particles.
Ionizing: Alpha (He-cores), Beta (electons), Gamma (EM), Neutron (neutrons), Röntgen (EM); generally EM above 100 nm
Non-ionizing: EM below 100 nm

A Positron.

I stand corrected. Yes positron it is!

I think it was Newton, Einstein and Hawking. That's the trinity right there!

another one. Concering the Heisenberg uncertainty principle again why is it impossible to determine the position and motion of any given particle?

Because if you look at something you disturb it.

You pretty much got it. Bravo!
I feel extremely extremely under appreciated in Physics class at school. Most people in the class are trying to wrap their minds around the fact that the Sun is a Star and not just a pretty light in the sky.

Default Sure!

Sounds fun. I once tried to give a presentation about transporter physics to my famiy but no one wanted to hear it.
