This group might get a kick out of this.
Imagine writing a calculation down on paper and the paper magically
working out the answers. We have built a calculator that works like
this, which is ideal for pen based computers and interactive whiteboards
in classrooms. It recognises your
I think Barbie summed it up best: Math is hard.
Even most people who are good with computers find math hard. There are
many programmers who have trouble thinking in recursive/dynamic
programming terms, or who have trouble with the sort of simple 3D vector
math found in games. As such,
Pi shows up in many areas that have nothing to do with geometry. For
example, the integral of exp(-x^2) over the whole real line is sqrt(Pi).
Also, the infinite series 1/1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 + ... =
Pi/4.

It has a geometric interpretation. But there are places where a real
number line is useful beyond denoting locations times in our universe.
The original poster was saying that, where gravity warps space
strongly, we would no longer use Pi. I was saying we would, since it

Hey Phil,
If I understand you correctly, I think you're very right. The
information we have about the world is behavior and appearances, and for
most interesting things the mechanism is completely hidden from us. We
can observe inputs and outputs, but not the source code. We can see

Aren't the main causes of hunger political rather than supply or

world population many times over. The poorest countries seem to be run
by despots that use food as a weapon. Although, I'm not sure how

Frankly, I'm disappointed.
The FRIAM list has been through several very philosophical
conversations over 3-4 weeks, all purporting to be complex. Yet
when I ask for a formal treatment, I get no answer.
Does this mean, for complexity, there's no There There?
There was actually a series of brain simulations done a few years ago.

I suspect you'd like Hans Moravec's books:

http://www.amazon.com/gp/product/0195136306
He uses Moore's law and estimates of the brain's computing power to
calculate when we'll have human equivalence in a computer. I forget
the date, but it's not

the claim (for which the author provides some limited evidence) that it
is now impossible to get on in physics academia unless you drink the
string theory kool-aid. Whither (or should that be wither) academic
