Today's Science Natterings I was just at the bookstore leafing through Bill Bryson's new book A Short History of Nearly Everything. In a section dealing with the sensitivity of radio telescopes, he says (drawing on observations by the late Carl Sagan) that the total energy of all the signals received from outside our Solar System (in the history of all the radio telescopes on Earth) is less than the energy of a single falling snowflake. This gives me enormous amounts of new respect for either scientists or snowflakes. I haven't figured out which, yet.
