I've noticed that, while incredibly intelligent, PhD.s are rather lacking in the common sense department. I shared a lab with a guy who, while not a PhD, had been accepted into Cornell Medical School (many years ago, but accepted there nonetheless). One day, he was rinsing glass wool in 99.99% pure hexanes, which are more flammable than gasoline, and it wasn't drying fast enough for him. He wanted to go to Saratoga Race Course and lose some money (
lots of money), and he couldn't wait for the glass wool to dry . . . so he put the whole mess (a soaking-wet with hexanes piece of glass wool the size of a
softball) into an oven that was set at 140 degrees Celsius. He just did get the door shut when it cooked off. He didn't get hurt in the fire (no one did, because it was minor), and I walked into the lab right as it went out. When I heard the start of the chemist's explanation, I
had to leave, and I very nearly choked from laughter. I went back into where Jim was, and said to him, "You may be a ****-up, but you are
our ****-up, and I will defend you until I die."
Literally, I was like this . . .
