Being an engineer myself, I was embarrassed and saddened to learn that Harold Camping received a B.S. from Berkeley in Civil Engineering.
What was the evidence based on which he formed this prediction? The core â€œproofâ€ rests on a numerological argument which derives the exact number of days since Christâ€™s crucifixion. Among the fascinating parts of his argument are ideas such as that â€œ5 symbolizes atonement, 10 represents completeness, and 17 is for heavenâ€. This kind of blurring of the line between metaphysical concepts and the world of numbers is common among religious scholars. A good example of this is biblical numerics which is the â€œstudyâ€ of numerical patterns in the Bible.
This kind of abuse of numbers is not an exclusive practice of the religious folk unfortunately. It is common amongst engineers and scientists too. In fact, with the advent of computers, modeling and simulation has become a major source of it in science. We form a model of the phenomena under consideration, and based on that model make predictions. The assumptions underlying the model model can be tweaked to achieve almost any desirable conclusion. Itâ€™s the job of the scientific community to question the validity of the assumptions.
Thatâ€™s probably the biggest difference between scientists and followers of Mr. Camping: the willingness to question. The similarity, on the other hands, is that both communities have an admiration of numbers. Somehow, quantifying concepts makes an argument appear more grounded in reason and logic. But of course, this is an illusion, as the argument must also be grounded in real-world observed data (thatâ€™s reproducible).
The proof of the argument I make in this post is the brilliant insight by Douglas Adams that the answer to life, the universe and everything is 42.
