“When Bloom discovers that Stephen Dedalus is living in the city, the two arrange to meet on the Number 11 Outer Circle tram so the “Bull Ring Befriending Bard” can take him on a guided tour of the city’s key residential areas, even though most of them are still fields. Unfortunately, Bloom boards a number 11 that is travelling along the route in a clockwise direction and Stephen boards another heading the opposite way. As a result the two characters never actually meet, although their respective buses briefly pass each other in Cotteridge. This seems to be an oblique reference to the Copenhagen Interpretation of quantum mechanics which states that any two particles moving in the opposite direction will eventually pass each other in Cotteridge.”
