Pi Quotes (7 quotes)

De Morgan was explaining to an actuary what was the chance that a certain proportion of some group of people would at the end of a given time be alive; and quoted the actuarial formula, involving p [pi], which, in answer to a question, he explained stood for the ratio of the circumference of a circle to its diameter. His acquaintance, who had so far listened to the explanation with interest, interrupted him and exclaimed, 'My dear friend, that must be a delusion, what can a circle have to do with the number of people alive at a given time?'

If pi wasnt around, there would be no round pies!

The Biblical value of pi, by comparison, is exactly three, as is clear from a verse in 1 Kings vii 23: 'and he made a molten sea, ten cubits from brim to brim, and his height was five cubit; and a line of thirty cubits did encompass him round about.'

What good your beautiful proof on [the transcendence of] π? Why investigate such problems, given that irrational numbers do not even exist?

[As a youth, fiddling in my home laboratory] I discovered a formula for the frequency of a resonant circuit which was 2π x sqrt(LC) where L is the inductance and C the capacitance of the circuit. And there was π, and where was the circle?
I still dont quite know where that circle is, where that π comes from.
