This was originally in The Big Bang Theory TV series (which by the way I do recommend to everyone! This show is both clever and hilarious at the same time!).
– Sheldon was giving this riddle to Penny and Leonard – they both failed, although Sheldon was considering this riddle to be very easy.
The expression we’re guessing is something from physics…(quite well known thing – even for the general public).
Here’s the solution:
- hydrogen atom, H, plus pigs minus P = Higgs (“h*igs”)
- bow, plus General Zod trapped in the Phantom zone = Boson (“bow*zone”)
- pear, plus tickle =Particle (“pear*tickle”)
= Higgs boson particle
