Science Jokes


  1. Two atoms walk into a bar. One says to the other, "I think I've lost an electron!" "Are you sure?" "Yes, I'm positive!"
  2. A neutron walks into a bar and asks, "How much is a beer?" The bartender says, "For you, no charge."
  3. The tachyon orders a beer. A tachyon walks into a bar.
  4. Why Did the Chicken Cross the Möbius Strip? To get to the other side.
    Caveat: nerds of the world are arguing if this joke should end with "same side" or "other side". One point of view is that a Möbius Strip only has one side. But if you started and experiment with fast chicken-a and slow chicken-b on opposite sides (from a local perspective) of the same plane, fast chicken-a would eventually catch up to slow chicken-b. Time to test this hypothesis with an experiment: cut a strip of looped paper then fuse it end-to-end so it is now a loop with no twist. Draw a colored line on the inner surface of the loop. Now cut the loop, insert a twist, then close the loop. Moving 360 degrees around the loop allows you to traverse the surface with the colored line while another 360 degrees allows you to traverse the surface without the colored line. I now forget why the joke was funny  
  5. Some helium floats into a bar. The bartender says, "Get out! We don't serve any noble gases in this bar." Helium doesn't react.
  6. A neutrino walks into a bar. The bartender says, "Get out! We don't serve any neutrinos in this bar." The neutrino says, "Don't mind me; I'm just passing through."
  7. A room temperature superconductor walks into a bar. The bartender says, "Get out! There are no superconductors allowed in this bar." The room temperature superconductor leaves without putting up any resistance.
  8. Two bacteria walk into a bar. The bartender says, "Get out! We don't serve any bacteria in this bar. The two bacteria say, "Hey, but we work here. We're staph."
  9. Schr�dinger's cat walks into a bar... and doesn't.
  10. A parasite walks into a bar. The bartender says, "Get out! No parasite are welcome in this bar." The parasite says, "Well, you're not a very good host."

  22. Two high school chemistry students walk into a bar tended by an irate Ph.D. chemist who was down sized from a major corporation. The first kid says, "I'll have some H20." The barkeep serves the water, knowing there will be no tip. The second kid says, "I'll have some H20 too." The bartender says, we don't serve minors in this oxidation state.
