  4. THIRD, a very, very few alpha particles were turned through an angle of 90 degrees or more.
  5. SECOND, some of the alpha particles were deflected only slightly, usually 2 degrees or less...
  6. Those alpha particles, of course, continued on a straight-line path until they hit the detector screen.
  7. FIRST, almost ALL of the alpha particles went through the gold foil as if it were not even there.
  8. There were 3 major findings...... (oh gosh this is gonna be long -__-)
  9. Just so you know, Hans Geiger and Ernest Marsden aimed a stream of alpha particles at a thin gold foil for several months in 1909 👍
  10. I was confronted with some rather bizarre alpha-particle behavior that I had to explain.
  11. Actually, I was the one who discovered them. I'm awesomeeeeee!! :D
  12. I had been studying alpha particles since 1898, in case you didn't know! :D
  13. I feel smart!
