MATH PUZZLE: Can you replace the question mark with a number?

Denis Papin

Born 22 Aug 1647; died c. 1712 .French-English physicist who invented the pressure cooker (1679). He assisted Dutch physicist Christiaan Huygens with air-pump experiments, and went to London in 1675 to work with the English physicist Robert Boyle. A few years later, Papin invented his steam digester (pressure cooker), a closed vessel with a tightly fitting lid that confined the steam at a higher pressure, considerably raising the boiling point of the water. A safety valve of his own invention prevented explosions. Observing that the enclosed steam in his cooker tended to raise the lid, Papin conceived of the use of steam to drive a piston in a cylinder, the basic design for early steam engines. He never built an engine of his own, but his idea was improved by others and led to the development of the steam engine, a major contribution to the Industrial Revolution.

The Darwinian vs. God Contest

One day a group of Darwinian scientists got together and decided that man had come a long way and no longer needed God. So they picked one Darwinian to go and tell Him that they were done with Him.
The Darwinian walked up to God and said, "God, we've decided that we no longer need you. We're to the point that we can clone people and do many miraculous things, so why don't you just go on and get lost."
God listened very patiently and kindly to the man. After the Darwinian was done talking, God said, "Very well, how about this? Let's say we have a man-making contest." To which the Darwinian happily agreed.
God added, "Now, we're going to do this just like I did back in the old days with Adam."
The Darwinian said, "Sure, no problem," and bent down and grabbed himself a handful of dirt.
God looked at him and said, "No, no, no. You go get your own dirt!"
