Why do flying creatures find it really easy to get in windows when slightly opened, but have trouble exiting when you open the door to let them out?
In: Biology
Say there are 100 bugs flying outside your cracked window. After 1 hour, one of those bugs manages to find its way through the crack.
That’s 1% of the population that has managed to find the crack in 1 hour.
Now consider the situation from the inside — if it took 1 hour for 1 bug of the 100 to find its way through, what chance does that single bug have to find the crack to escape?
This is a situation very closely related to entropy, and you might find [Maxwell’s Demon](https://en.wikipedia.org/wiki/Maxwell%27s_demon) an interesting concept to read up on.
