The circumference is the same as the length of the string

Shucks Thanks

217959 2004-02-26 00:01:00 no...........MrBeef I reckon a circle has NO length...........it DOES have a diameter/circumfrence etc but length ?.........hmm...... drcspy (146)

Thank you Neil, it is nice to be back. :-)

And I have a sore throat, not "sort" throat. Shouldn't have been up posting so late at night. :8} :p

217962 2004-02-26 22:12:00 Of course Billy overlooks Heisenberg's Uncertainty Principle which says that the act itself of observing the string will affect it's properties .

And if the string is with Shrodingers cat in its box then we have a real problem : is the string there or not? Does it exist in another universe? How can it be measured?

At least the relativistic problem is neatly solved by Tony's solution: the length of a fast moving string yields two results in terms of the remote observer and the string itself, but both are equally valid .

And then there is Superstring which gets into quantum physics and unfortunately Tonys answer is of no help . :(

Not so, my friend. If you place yourself at the centre of the string, which ever way you look the string halflength is the same. The Superstring folk are all in a twist right now trying to work inflation into the eq so that they can deal with the "flatness problem". But then, what is the length of this thread ??
