Scientific Method

Key Questions

Explanation:

And so an application of the scientific method. Have you ever lost your house keys or your car-keys (of course you have!). And so the scientific problem is defined....$\text{where are my £?""!&@ keys?}$

And so we ask the questions...

$\text{When did I last use them?}$

$\text{To where did I go after that?}$

$\text{Does the wife have them?}$

$\text{Are they in my coat?}$

...and of course other questions are appropriate to ask given your personal circumstances. And while no-one can have a perfect memory, each time you ask a question, and potentially falsify it, you narrow down the true location of the keys....
