We are currently moving into the “dog days of summer.” It is the time of year when the dog star, Sirius, rises and sets with our own star, the sun. It was once thought that because both stars were rising at the same time, we must get hotter because of it. In fact, it doesn’t even add one degree to our heat. The phrase “dog” days goes back to the early Roman empire. We now know it is the tilt of the earth that makes the sun’s rays more direct this time of year and, in turn, makes it so hot.
