# Further to the newsletter
I have done some investigating and there IS and answer!

it's not a perfect system, but I think people know what they're letting themselves in for.

May not be to scale.

Apparently 13 and a half inches. But it's probably no more than 10 inches in a good light.

# i normally go for
2(X+1)-1 over 2 = X

where x is the piece of string.

Edit: now expand!

no it's the meaning of the universe, but only if x = 42

# You just need to subtract
the portion of the universe that does not contain the piece of string from the entire universe, to give you the length of the piece of string.

# No, that would give you....
.... the four dimensional volume of the string (presumably in secondcubicmetres, if you were doing it in metric).

# From there it's just a simple matter of higher dimensional integration
of the hyperspherical space-time footprint of the string, to give you its empirical length.

I had assumed that step was basically too trivial to mention in the above method.

# Which leaves us the simple matter of measuring the universe


Due to the quasi-reciprocal nature of space time, measuring the external universe except the piece of string will also involve measuring the measuring device, but since space time is curved, this should pose no problem to oh god it's friday I can't be bothered have a good weekend.

# The Correct Answer
If you form the string into a circle and measure distance from the centre of the circle to the edge (ie the radius you can calculate the length of the string using 2.pi.R

This leaves the small problem that if we had such a measuring device, the question could be answered by simply measuring the string, an alternative solution must be sought.

Let us make some assumptions:
The string is at least 1cm in length
Any smaller and calling it a piece of string is perhaps a misnomer, fluff would be a better definition.

The string cannot exceed one ton
Manufacturing such a string would be impractical, and would instead of being named string, would be better termed as a tourist attraction.

String is no thinner than 1.5mm
Thinner than this, and we are entering the territory of thread.

Worst case density is 0.7kg/litre
Otherwise the string will be too weak.

So, we know the maximum weight, and the volume:

1000
---- = 1429 litres or 1.429 cubic metres.
0.7

Therefore, maximum length is

Volume 1.429m
------ = -------------
Area pix0.5mmx0.5mm

So the string length lies between 1cm and 11,644.39km which can be expressed as above

thanks for taking the time to clear up the matter, it's been bugging me for a while.
