Hi All!

Love logic and puzzles (obviously eek), this looks to be a fun place to exercise the brain!

Re: Hi All!

Hi logical1;

Welcome to the forum!


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Hi All!

Hi! Welcome aboard!

Have you run across G. Spencer Brown's "Laws of Form" and his notation for two-valued logic?
It introduces a notation that uses a single symbol (in addition to the p,q,r,... for statements) to
represent and, or, implies, if and only if, not, and the truth value "T".  The system of notation is
phenomenal and makes calculations of truth values extremely easy.  Paying attention only to the
notational system and its rules of operation is really neat.  But trying to understand his more or
less (according to me) "philosophical" language of "distinctions, crossings" etc is another matter.
I gave up on it and just took the notational system and ran with it.  Works really great.  Oh, and
the one symbol also does grouping.

I think there are sites where you can download it for free.  Enjoy!  smile


Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).
LaTex is like painting on many strips of paper and then stacking them to see what picture they make.

Welcome to the forum!

This is a great place to exercise the brain.  I'm still 'overheating' on phrontister's puzzles.

Next job.  Look at the Sam Loyd puzzle you mention.

Hi logical1!

Welcome to the forum!

So far I like the games here, although, admittedly, I haven't done many.  Hope you enjoy the games in that case!
