Exit polls taken on election day are held because the counting of votes requires a few days and there is a desire to know already how the vote is. A number of people ask at the exit of the polling station how they voted. If one does that in a large number of polling stations you can pretty accurately predict the outcome of the vote in that way.
Why do we not wait those few days? Why do so many fathers and mothers like to know if there is a boy or girl coming? That is our curiosity which is ingrained within us. Everything that is unusual we want to know what it is and what it serves. Animals have that also, if you go through a meadow with cows in it, they all trudge behind you, wondering what kind of strange animal you are ?
Newspapers and TV programmes exist thanks to our ongoing hunger for news.
More so : it is thanks to our curiosity that we live in a technically highly developed society as comfortable as we do now.
Archimedes (287-212 BC) is lying in the bath and out of curiosity he asks himself why he is sitting in water less hard pressed on the bottom than when he is on the dry.
Then he transforms, in his thoughts, his body to one that exists out of water. He now understands why: the body of water remains in place, because the upward force of the surrounding water is equal in size to the downward.
So the upward force on a submerged body is equal to the weight of the displaced volume of water.
The law of Archimedes was born. At that time there was still no practical application for his law but later, we were able to build ships and submarines with it.
A large part of physical science is driven by curiosity. Many laws have emerged because of this curiousity through which we have so much ingenuity around us.
We spent billions to watch the Higgs particle. There is still no practical use in existence because of this find, but that will surely come.
And then we live a bit easier and ..... a little longer.
