On Coast to Coast AM this morning, the topic was the Shroud of Turin. If the supernatural one wanted more involvement on the physical plane, by now, he/she would have sent more prophets for you to bend, fold, staple, and mutilate. :) -- Regards, Casey ... 5 Apr 2010 12:45

Time spent by an algorithm
Hi, I am measuring the time spent by an algorithm. Let's assume it is a gaussian-distributed random variable. How many repetitions do I have to make to get a good estimate of the mean and standard deviation of this distribution? I'd like a cook-book answer this time, because I am in hurry with these measu... 6 Apr 2010 18:44

Most *elementary* Q on quotient map of topological spaces
This is the most basic question possible: a definition (I can't find it online). In a different thread ( <120e389f-6f19-49d9-b1f9-1240cff7eb8b(a)35g2000yqm.googlegroups.com>) drhab <habrozius(a)gmail.com> writes: ...let A be a subset of topological space X. Let q:X->X/A be the quotient map... How is the ... 11 Apr 2010 03:41

iscomposite( n^n + 2*n + 1) always ?
Many thanks to all those who supplied an answer (even 12 years ago!). No Kent, it wasn't homework and I should have thought a little longer. Actually, there's even a easier way to find the answer: f(n)=n^n + 2n + 1 in a certain sense behaves like a polynomial, since "If n is even then f(-1)=0 therefore f(n) is divi... 6 Apr 2010 03:10

X,Y Top. Spaces, f cont:f: X-- --Y is nullhomotopic if X is contractible
Am 05.04.10 05:20, schrieb Bacle: Hi, everyone: Let X,Y be topological spaces, f:X-->Y a cont. map. I am having trouble seeing that if X is contractible, then for any Y , f is nullhomotopic. The opposite direction, i.e., g:X-->Y, with Y contractible is clear, but not this direction. An... 5 Apr 2010 06:07

From the book: "How to Succeed in College Mathematics - A Guide for the College Mathematics Student", Richard M. Dahlke, Ph.D., 2008. Main Idea: He says that Calculus 12 is worthless, UNLESS it prepares the student to write the AP Exam, either AB or BC. From page 63: Calculus AB has some content on elementa... 4 Apr 2010 21:30
