23. Particle Interactions: A tale of tracks

24. With only one set of tracks, we must infer the passage of something known to leave those kinds of tracks

25. Two sets of tracks require an interaction:
What happened here?

26. One possibility: not an especially conservative one…

30. Yummy!

31. Many types of interactions may be observed
Here’s an important question: if all you saw were these tracks, how do you know which way this goes?

32. Some interactions leave no tracks. Is this just a detection problem
Some interactions leave no tracks! Is this just a detection problem? Or some real property?

33. Conservation laws assure us that all interactions play by the established rules.
