Magical Pi

Today I watched a bit of "The Life of Pi" - a great movie.
It prompted me to consider the magical number Pi, a non-repeating decimal value that is a major part of mathematics.
Many years ago I memorised it to 16 decimal places - 3.1415926535897932..... etc etc etc.
I got to thinking how strange it was that it is the essential component of the formula for calculating the circumference of a circle in relation to the radius (2 Pi r), and how it also features in the formula for calculating the area of a circle (Pi r^2).
The circumference is a liner dimension, and the area is obviously an area dimension, and these 2 values are completely separate entities. Why is it so? How come this ratio that we call Pi is an integral part of each of these separate computations?

Gardening Time

Today was all work and no play. We dug out the 2 bushes on the patio. They had become root bound and it took a strenuous effort to dig them out and prepare the ground for some more suitable vegetation.
In the meantime the planting effort by Cath on her recent visit, is all looking positive.

Some Good Things in Life

Eating is one of them.
Here we have a successful apple pie by Helen.
And here we are about to have our fill of a great meal on Easter Sunday.
