Why do ships have cicular windows,why not square ones?

Try this, you only need paper and scissors. Take two sheets of paper, on one of them, cut out a corner in a rectangle shape (so your sheet looks like a very thick L), and on another, cut out a quarter circle instead. Now try to pull apart the corners that you created by cutting out, like trying to make the part you cut out wider – you will notice it is harder to do with the smooth, curved cut, while the one with the right angle will start tearing at the point of the angle right away.
