*pi*to the nth digit. I guess this was our equivalent of being able to down a shot of tequila without barfing, although in this case, regurgitation was required. I always had trouble getting past the 7th digit; for the following cartoons, I actually had to look in the Nerd's Bible, formally known as the CRC Handbook of Chemistry and Physics.

I should note that it is not necessary to own a copy of the CRC Handbook to know

*pi*(**π)**out to the 100th digit. You can look up a whole etymology of*pi*on Wikipedia, although in keeping with the Wikipedia tradition of factual reliability, every digit beyond the 39th place is inaccurate.*Pi*

**is not the only number which has a train of significant digits reaching into the infinite. Among the many different constants in mathematics, there is**

*e*.

For those of you who are still in grade school (and those of us for whom senility has started robbing us of our mental knowledge of the trivial),

*pi*is the circumference of a circle divided by the diameter, while*e*is the point at which the derivative of the function e to the x equals 1, when x is 0.There is another, more obscure constant...

I should mention that the CRC Handbook is a venerable compendium that is now in its 91st Edition (my copy, which still resides on a bookshelf in my office, was the 54th Edition). It is known for its functionality and versatility. And it is entirely indispensable.
