### I'm losing faith in physicists

QuoteOriginally posted by: rmaxQuoteOriginally posted by: NThe particle is a type of (fancy) wave and as a wave it goes through both slits. To observe it, you need to time-average or take the absolute value.But when I place my detector at a slit, I measure a single discrete event at one slit, and no on the other. I also no longer get a diffraction pattern on my screen, but get two spikes...That's exactly right... A detector in order to work, must interact with the wave and thus changes the geometry of the experiment.It turns out that this is a very hard experiment to instrument properly. That's why I stick to math and QF.

What one needs here is the generalised uncertainty principle.QuoteWhile understanding the details of string and superstring theories requires considerable mathematical sophistication, some qualitative properties of quantum strings can be understood in a fairly intuitive fashion. For example, quantum strings have tension, much like regular strings made of twine; this tension is considered a fundamental parameter of the theory. The tension of a quantum string is closely related to its size. Consider a closed loop of string, left to move through space without external forces. Its tension will tend to contract it into a smaller and smaller loop. Classical intuition suggests that it might shrink to a single point, but this would violate Heisenberg's uncertainty principle. The characteristic size of the string loop will be a balance between the tension force, acting to make it small, and the uncertainty effect, which keeps it "stretched". Consequently, the minimum size of a string must be related to the string tension.Everything you wanted to know about String Theory but were afraid to ask.

### I'm losing faith in physicists

out of curiosity N just how is the very sticky issue of measurement treated in your neo theory? You started to allude to the problem of the indivisibility between a system and measuring device to test your ideas and here perhaps some reality is creeping in....

And for measurements, I use a stopwatch and ruler, remember I'm just a quant.

I know because I got the supersymmetry T-shirt last year. Who's Conway?

I'll reciprocate with pdf's of the papers I presented last year, plus an agenda for the 05 ANPA meeting so you can get an idea of the format. John Horton Conway is a fellow Liverpudlian, as, coincidentally, are several other members.In my blind search for more detail on ANPA, it was Brian Josephson who kindly got me there, literally on the day.You will be in good company.

Misaligned and misunderstood.N and Newton, hmmm...For me N looks more like a speech generating algorithm fed in with a restricted set of consepts like "supersymmetry ", "string theory" and "Riemann conjecture". Semantics is probably still on a TODO list.

QuoteSemantics is probably still on a TODO list.Choose between algebra and analysis. Don't mix them.I would like to see Cayley maps for PDE.
