I learned pi to 15 places while I was still at school. 3.141592653589793 --- try converting this to a date AND time. When is that?

I hope I have still got this right as my schooldays were a long time ago and my memory is not what it was.

I round it off to 3.1416. :roll: Close enough for most (basic) calculations.

And my favorite dessert is pie, any flavor. :wink:

The one thing that π and I have in common is that we are both absolutely and inconvertibly irrational … :mrgreen:

and just google "incorrect value of pi"

Now, will someone tell us what the relationship of pi to music is? :-)

I was looking for a pertinent link, but couldn't; perhaps these links were not as good on this issue as I thought.
I only quickly glanced at them. My bad.

Whether they are a load of tosh: I don't know. As I said, I didn't read them.

But: I recently discovered a brilliant insight by someone about the Fibonacci numbers, even though he is not a mathematician and interprets everything in light of kabbalistic numerology, which I personally do not subscribe to. We need to remain openminded and not dismiss or even judge everything we encounter, just because it happens to be outside our comfort zone.
