Physics

I have also had such difficulties

Hi Kurt and Zane
Feynman diagrams are line drawings that represent how subatomic particles interact ... or decay. They can make it easier to understand what results from an interaction.

To see an example, go to ...

* First diagram shows the decay of a muon. Notice time on the x-axis. Time moves from left to right. There is no scale but there were they would be tiny fractions of seconds.
So 'reading' from left to right, you see a muon existing for a short time before it decays (at the dot) into a muon neutron (green line) and a W- particle (wavy line).
* Second diagram also shows a short time later (at the next dot) when the W- particle decays into an electron and a neutrino.

If you can be more specific, I might be able to help you understand better.
