On the point of pi being officially declared as 3 - I do not know the background but I hasten to point out that a stumbling block both to mathematics and science is the precision of the measure.
If you and I set out to measure a coastline but used rulers of different length, the shorter ruler would yield a larger result than the longer ruler. But both would be accurate according to the measure used.
That is the common example used to explain fractals. A fractal is an object or quantity that displays self-similarity on all scales.
Lurkers interested in seeing what a fractal looks like, click here for the Mandelbrot set. And then continue to click on a point of the graphic to zoom in, etc.
Yes, and for sufficiently large values of 1, 1+1 can equal 3 or any number really : ) Math is just a tool that we use to try and describe reality, it doesn't create reality, although some mathematicians may think otherwise.
