Love arguing but don’t feel like watching Sarah Palin talk in her grating, nasal whine for an hour tonight? Why not start your own argument? Mention any of these topics while out having drinks or dinner, and then just sit back and watch: 1.) The airplane on a treadmill question. In the discussion on that link, the topic went on for fifteen pages. 2.) Does hot water boil faster than cold water? 3.) Can water be colder than 32°F and not be ice (here’s the answer in video form) ? 4.) If the curved top of an airfoil makes airplanes fly, why are the most efficient airfoils curved on both sides? Okay, that one’s a little nerdy. I asked an airline pilot the question once, and he said “put enough THRUST behind it, and a BRICK’ll fly”… Got any more to share?
