"That's one small step for man, one giant leap for mankind."
They were also to achieve the remarkable feat of catching such a jump in midflight and reversing it.
Or the remarkable feat of catching a lady in mid-spin and reversing her:
A quantum measurement influences the system being observed: The act of observation injects a kind of random noise into the system. This is ultimately the source of Heisenberg’s famous uncertainty principle. The uncertainty in a measurement is not, as Heisenberg initially thought, an effect of clumsy intervention in a delicate quantum system — a photon striking a particle and pushing it off course, say. Rather, it’s an unavoidable outcome of the intrinsically randomizing effect of observation itself. The Schrödinger equation does just fine at predicting how a quantum system evolves — unless you measure it, in which case the result is unpredictable.
Without the indefinite article, there is no clear distintinction between "man" and "mankind", so you can trick your perception into observing small steps or quantum leaps. Out of many, one.
Acts 2:1 And when the day of the 50th was fully come, they were all with one accord in one place.
It "just so happens" that the Washington Monument is about to reopen with a new elevator system. Nothing random about that.
Living parables for the win!
