Re: Majoring in Math

There has already been plenty of good advice offered here, but I'll throw in my own two cents since I'm over the finish line on a similar journey. I was a freshman at 30 -- just out of the army -- thought I'd be an English teacher. I rediscovered math in college algebra, the lowest level of math cou...

Re: What material is covered in a college algebra course?

The original post for this thread was not ambiguous: the question was what algebra would be needed for a (presumably first) course in calculus. Whether one thinks of this stage of learning mathematics as appropriate to children or post-docs isn't relevant, at least not to the poster of the question....

Re: How much of a math nerd are you?

Man, and all I do is fiddle with a digit system I concieved based on the factorials (i.e. the base for each digit is the place of the digit +1, such that the series 1, 10, 100, 1000 in my system correspond to n! - fractions use 1/n!, and I suspect there are interesting properties to it). I can't se...

Re: How much of a math nerd are you?

Ended's analysis of "Is this question singular?" is brilliant, and leads to the obvious next question, "Is this question non-singular?" The latter appears to be a paradox of the Epimenides type; it can only be answered incorrectly.

Re: How much of a math nerd are you?

So, let's say a question is singular if it has only one possible correct answer. Example: "If testator one says 'exactly one of us seven is lying' and testator two says 'exactly two of us seven are lying' and ... and testator seven says 'exactly seven of us testators are lying,' then which of t...

Re: Logic And Conditionals

Couple of thoughts, The Godel Incompleteness Theorem, which I think you are referring to, has to do with the "completeness" of a logic, to grok which you must separate the notions of "true" and "provable". (Logical) truth is a semantic concept, and refers always to trut...
