Erwin Schrodinger: The chicken doesn’t cross the road. Rather, it exists simultaneously on both sides…..just don’t peek.
Richard Feynman, 2: There was this good-looking rooster on the other side of the road, and he figured he’d skip all the games and just get to the point. So he asked the chicken if she’d like to come over to his side, and she said sure.
Richard Feynman, 1: It’s all quite clear from this simple little diagram of a circle with lines poking out of it.
Werner Heisenberg: Because I made darn sure it was standing right next to me on this side.
Enrico Fermi: In estimating to the nearest power of 10 the number of chickens that cross the road, note that since fractional chickens are not allowed, the desired power must be at least zero. Therefore, at least one chicken crosses the road.
Henri Poincare: Let’s try changing the initial position of the chicken just a tiny, tiny, tiny bit, and….look, it’s now across the road!
