somewhat revised dates for the Oblig

An earlier message, given a few weeks ago, read as follows:

"The Oblig (obligatory exercises) dates are now set. On Thu Nov 1 the set of exercises is made available; by Mon Nov 12, before 12:59, you hand in your reports. This needs to be done via the Devilry System [sic]; more details regarding this later. Expect both theory and practice, so to speak."

Apparently certain rules imply that the Oblig should have *two weeks of time*, which means that I'm now revising the above to (i) starting date Tue Oct 30, (ii) deadline for handing in report Tue Nov 13. More details will come later.

One more thing, regarding the four-hour exam: Students will be allowed (by me) to bring with them (a) a simple calculator, with no memory, just enough to compute \sqrt{49} and a bit of \log and \exp, perhaps; (b) *one sheet of paper, in their own handwriting* (where they may write anything they want, from E = mc^2 to a formula for the mean of a normal distribution with mean zero, and in as tiny a handwriting as they manage) -- but no book and no other aids.
