particles

I have only a popular science understanding of quantum physics, so pardon me if my questions are misphrased. In the famous two-slit experiment (let's say using electrons), a stream of particles are aimed at the barrier between two vertical slits. The characteristic interference pattern shows up...

Hey. I had a discussion with a friend about matter and energy. I was under the impression that: - that matter and energy are fundamentally made out of the same stuff. - atoms are made of certain particles (electrons, protons, neutrons) which are actually exactly the same just in different...
