When the famous Sherlock Holmes found out that his main homicide
suspect was actually playing soccer with some 20 other players at the time of
the crime, he reasonably concluded that someone else must have committed
the crime. Why?
Simply because his reason told him that the suspect could not have been at the
crime scene and at the soccer field at the same time. But how did we draw this
reasonable conclusion? I guess it is out of experience. Sherlock,
his friends, and everyone else never experienced someone being at two places
at the same time.
But is the fact that we never experienced it enough to conclude that it can
never happen?
It actually did happen! Not for a man though
Quantum theory has proved that particles can exist at two places at the same
time.
So imagine another Sherlock Holmes coming from the tiny world of particles facing
the large Sherlock Holmes Her is the conversation they had:
- Why did you exclude this suspect from your investigation?
- Are you out of your mind! He was playing soccer at the time of the murder!
- So what? He could have been playing soccer and killing the victim at the same
time.
-
Besides the murderer is a tall man according to all the witnesses. However
the suspect is rather short
- So what? He was tall when the witnesses saw him, but became shorter when you
looked at him. That is very common in our world of particles. Tell me Sherlock,
where did you learn these stupid rules.
- It is common sense..
- But who taught you this common sense?.
- Experience taught me.
Then if you were to have a different experience, you might have a different
common sense?
- I dont think so.
- Dont you see my dear, that by being reasonable, you are being completely
unreasonable!
