A...and, adds some weight to the notion of Inconvenience in Pynchon, yes?

Prashant's characterization of "i" as a "convenience" reminds me that's how Poikler describes delta t to Leni.
"The important thing is taking a function to its limit. Delta t is just a convenience, so that it can happen."
Leni thinks it's just his way of removing all the excitement from things . . . .

There was a result in Nature recently that proved that the wavefunction is not just a statement of knowledge, it represents more than just probabilities. If anyone is interested I can go into this, but the short answer is Witt was wrong

Imagine a 2D graph, the vertical axis marked with multiples of i and the horizontal axis with real numbers. So on this 2D graph we can define a complex number as a point. Call such a point s = \sigma + \rho, \sigma and \rho being real and imaginary numbers resp.

If I have a RZ function, writing R as a function of s as R(s), the zeroes are the values of s for which R(s)=0. The Riemann Hypothesis (unproven) states that the zeroes of the RZ function have real part 1/2. Formally, R(1/2 + \rho) = 0. This gives you a line on the surface of the RZ function (known as the critical line) along which the zeroes are hypothesised to lie. That wasn't too bad, right?
