Today, March 14, is Pi day

I am by no stretch mathematical but Pi was not conceived in either an imperial or a metric system. Pi is Pi, irrespective of where it is being used.

I think if the diameter is metric then the circumference is also metric.

"Pi are squared".... No, "Pi are round"

And it's Albert Einstein's birthday.

Pi is a ratio, not a measurement.

It makes no difference whether you measure in feet, meters or lengths of a hummingbird's beak, it's still the ratio between the 2 measurements of circumference divided by diameter.

Pi are round. Cake are squared

It doesn't have to be only metric or imperial. For example, my height is 5 foot, 28 cm.

Pi that is divisible by 10: pecan
Pi too good to divide by 10: blackberry, lemon meringue
Pi too unpredictable to divide by any number: mincemeat

I read once that the West Virginia legislature passed a law requiring Pi to be defined as 3, not 3.xx, just 3.0. Apparently, in the Bible, there is a description of a lake where the distance around was three times the distance across, and they didn't want to defy the Bible.

Does the value of Pi change with altitude? Pi in the sky?

The week before last was National Pi(e) week in the UK.

In order to calculate the waist circumference of a full circle skirt, you must use Pi.

In order to calculate the waist circumference of a full circle skirt, you must use Pi.

But don't eat too much pi or the skirt won't fit.

Anyone else ever notice that 3.14 written backwards or read in a mirror spells PIE?

And let's just be clear the only pie is pecan pie, everything else is a poor pretender!

VAP, I will remember that forever.

Also, apple pi would like a word. ;)

I admit pecan pi is one of the best.
But a good cheesecake looks kinda like a pi to me.

This year pi was a chocolate cheesecake. And very good it was/is.
