I worry about Las Vegas schools. I hear in math, they only teach them to count to 21.
Life is girt all round with a zodiac of sciences, the contributions of men who have perished to add their point of light to our sky. . . . These road-makers on every hand enrich us. We must extend the area of life and multiply our relations. We are as much gainers by finding a property in the old earth as by acquiring a new planet.
