Imagine that Holmes and Watson discover a single tire track instead of a pair of tire tracks while walking down a path at the Priory School. Could Holmes and Watson determine the direction the cyclist was heading (assuming of course the tire track was made by a cyclist)? | |
It seems natural
to suspect that Watson would come to the obvious conclusion that the tire
track was created by a unicycle, and thus the direction can not be determined
from the track. However, one could imagine that Holmes would chide
Watson and draw on his famous question to Watson, "How often have
I said to you that when you have eliminated the impossible, whatever remains,
however improbable, must be the truth?", to consider the question could
a bicycle have created this single tire track.
Our goal in these pages is to examine this possibility. [The answer is of course yes, a bicycle can create a unicycle track.] |
