We are called the nation of inventors. And we are. We could still claim that title and wear its loftiest honors if we had stopped with the first thing we ever invented, which was human liberty.
Mark TwainIn the space of one hundred and seventy-six years the Mississippi has shortened itself two hundred and forty-two miles. Therefore, in the Old Silurian Period the Mississippi River was upward of one million three hundred thousand miles long, seven hundred and forty-two years from now the Mississippi will be only a mile and three-quarters long. There is something fascinating about science. One gets such wholesome returns of conjecture out of such a trifling investment of fact.
