Is there a mental exercise which has a tendency to order the mind such that the understanding and retention of mathematical concepts, symbology, and algorithmic procedure is increased?

Sometimes it seems to help if one is sober.Quote:

While I intentionally enjoy the occasional buzz, I am by no means a drunkard. The only substance's I have ever meet the criteria for psychological and physiological addiction to is nicotine and caffeine, and I have wholly surrendered the use of nicotine, though I suspect that addiction itself will be with me to the end of my days. I am currently drinking a cup of coffee right now.Quote:

This is the basic drill for developing the fundamental skill necessary to juggling.
I am asking for a drill that strengthens the fundamental skill's necessary to the study and understanding of pattern and order.
As an example, while travelling, picking two points on the horizon and using them, and myself as a third point, to visualize a triangle which would close down to a line segment as my ray of travel intersects the line segment formed by the two original points?
Or, whenever a discernable group of object's fall's within my vision, I could consider them a set, count them to discover the cardinality of the set, then group the set into subsets based on arbitrary equivalence classes?
Perhaps to never do a one to one count of objects in a geometric arrangement, but to always deduce their number from edge count and formula?
Thank you MagiMaster for the suggestion, though I can confidently assert that dearth of interest is not an issue.Quote:

It may help to brew a new pot of coffee.
I have ordered the book. It was affordable. Thanks.Quote:

I find it to be more rigorous, in depth, and clearer.
And after all the calculus texts I've failed to get anything from, I find that I am getting somewhere with Morris Kline's Calculus book. Although his Wiki page gives me the impression that most mathematicians might consider him a pariah.
I am a bit surprised at your feelings with regard to the book of Halmos. He is generally a model of clarity. I quite like that book. That said, it is naive set theory, not axiometric set theory. However, most mathematicians think in terms of naive set theory, and leave axiomeric set theory to logicians. There are exceptions, of course, and when real issues in set theory arise, there is no substitute for the axiometric approach. I do not know the book of Smulyian, yet. He is a logician. But I did order his book from Amazon, as well as Paul Cohen's book on the continuum hypothesis. Cohen is far more than a logician, and while he proved the independence of the continuum hypothesid, he also dif seminal work in harmonic analysis.Quote:

The only "good" calculus book of which I am aware is the (seldom used) book by Mike Spivak.
BTW do not expevct to read Ward's book quickly. The proper waybto go through it is one theorem at a time, and proving each theorem before you go to the next one. You can expect to take a year, working hard and steadily, to get tjhrough the book.
I second these comments on the Halmos book, I enjoyed in immensely.Quote:

Forget axiomatic set theory, it is a very dry subject.
Yeah, why is it "seldom used"? What little calculus I ever had stomach for was taught me from James Stewart's book of the same name, which is thorough, but somewhat mechanical.Quote:

I have Spivak, and, unlike Stewart, he explains the theory very well. I like it (but not enough to make me enjoy calculus).
I also recommend Birkhoff & Mac Lane A Survey of Modern Algebra, which starts from the very "bottom" and covers just about everything except topology and differential geometry. Every statement is proved, plus there are loads of exercises (always a Good Thing)
I got my copy from Alibris for about 10 euros.
BTW, it was Saunders Mac Lane who founded category theory, and one can almost sense the idea of this starting to come to him as he writes this book. As I like category theory, maybe I am biased, but I recommend the book thoroughly.
Silly or not, it is true.Quote:

The necessary topics are more than adequately covered in the introductions to real analysis, topology and algebra, including one's preferred version of the axiom of choice -- the axiom itself, Zorn's lemmsa, Hausdorff maximum principle.
Category theory is useful language, but is not likely to ever be regarded as "underpinning everything".
Birkhoff & MacLane is a fine algebra book, if a bit dated, for an introduction to algebra and number systems. It is not a substitute for books on analysis or topology. It does tend to dwell on the obvious at times.Quote:

I'm currently rather indulged in "A Book of Abstract Algebra" by Charles C. Pinter.
Anyhow, I was wondering if you had received your "Set Theory" by Smullyan yet. What do you think?
Set theory isn't hard, but it is a little tedious. The first order logic symbology in the Smullyan book threw me off a little, but there's a lot of context available, and The Wiki to reference, so I think I got a good handle on it now.
