Last week, my friends and I won a trivia contest at a bar, because our friend, Charlie, knew the answer to a random question about the history of air conditioning. This was one of the weirdest things I have ever heard in my life. Charlie knows a lot about a lot of things, but who knew that he’d know about this? He actually knew the name of the guy who invented the first air conditioner, and when he answered correctly, the two of us all just kind of stopped and stared at him in awe and disbelief. At that point, our trivia team was down and if we did not get the answer to this question, we would be out of the competition. When I saw what the question was, I thought for sure we would strike out. It was a bummer for us, too, because we had been doing so well in the competition series. Suddenly, Charlie rang in. At first, I thought it was a mistake. I thought that he had accidentally pushed his buzzer. Then, he confidently answered the question. He knew exactly who the father of modern air conditioning was! I suppose that my jaw hit the floor when he answered that question correctly. Later on, after the two of us had won the competition, the two of us were all asking Charlie how in the world he would know the answer to that question. I learned his dad was an HVAC specialist when he was growing up, and he used to study all about heating and cooling systems for fun back when he was a kid.
