I’m usually quite interested in the attempts of individuals to apply math to the Bible, and the Church Hopping blog has a fun little article about some people that are actually using interesting mathematical principles on the text of the Bible. Check it out.

UPDATE: Daniel from the Logos Blog has contacted me about a great post over on that site. As he said, “Thought you might be interested in today’s Logos Blog post looking at The Top 50 People in the Bible and using the IBM Many Eyes visualization. Cool thing is that anyone can play around with the charts and data…” Check it out here.

It happens to be the case that there are two different verses in the Old Testament which provide for an approximation of pi. In the NIV translation both I Kings 7:23 and II Chronicles 4:2 give the following measurements for a tank which would be enclosed in the “First” Temple:

He made the Sea of cast metal, circular in shape, measuring ten cubits from rim to rim and five cubits high. It took a line of thirty cubits to measure around it.

Taking these measurements along with the ratio for pi given as circumference over diameter we have a coarse approximation for pi of 3. While not astounding in accuracy, I’m always excited to see how subtle tidbits of mathematics invade even religious scripture. In other words, sometimes math is beautifully inescapable.

In you’re interested in learning more about these two verses I suggest reading an article called “On the Rabbinical Exegesis of an Enhanced Biblical Value of Pi” written by Shlomo Edward G. Belaga. An online version of the article can be found here. The article surmises that the Biblical narrative lends itself to a much more accurate approximation of pi. It’s worth a look if you’re intrigued by such ideas.
