The Beach

How many grains of sand are on the beach? And how many drops of water in the Mediterranean Sea? Since the Mediterranean Sea is connected to the Atlantic Ocean, and the Atlantic to all other oceans, we may as well ask how many drops of water are there in the world? And as all land is one, we may wonder how many grains make up the planet Earth? Only Earth floats in a void detached – at least, as far as we know. Gravity tethers us to the sun. It also tethers us to the Earth, water to the oceans, to the seas, and grains of sand to the beach. A day at the beach can be the most cosmic experience of all.
