Well so do I Damian!

I can spend hours browsing around and its the best I can find.

Now I have been enjoying receiving the Plus magazine for two years now and would like to recommend it to anyone interested as its very good.

Heres what the latest issue has to say of their new edition

"Issue 42 of Plus is now out! - [url]http://plus.maths.org[/url]


If you thought you knew what geometry is all about, then this issue of
Plus may
change your mind. We explore a strange point-less geometry of
spacetime, find
out about hyperbolic geometry's amazing fractals, celebrate a geometric
formula
named after Leonhard Euler, the most prolific mathematician of all
time, and
try to calculate pi. This issue also contains the first ever Plus
teacher
package and, to celebrate our tenth birthday, continues our series on
the
history of Plus."

Besides the normal articles they have now introduced the 'Teacher package'

which is worth collecting.

BTW: I was introduced to Plus by one of our members. I cannot recall now who it is but thanks all the same.

Not really a forum (although they have a small one) and not entirely math related:

Mally, the "Plus" site is really great. Thanks for the pointer

Thank you robert for acknowledging my post that 'Plus' was great. I look forward to it every month

You are one of the very few members who at least appreciate my intentions.

I understand you are stuck in 'God's own country'.

I have touched down many times in Dhaka but only rambled around the airport as we have a quick turn around to Kolkata.

Please let me know if I can do anything for you and all the best

I think all problems are math related on [url]http://projecteuler.net/[/url].

That's a great site. Currently I'm 99% genius on their rating system, only 1 problem missing from 158 problems.

Those problems look interesting on first scan.
Which one haven't you solved yet?
(I'm guessing #96 on Sudoku, but some of the others
look tricky too.)

Not Sudoku, I haven't solved #143 "Investigating the Torricelli point of a triangle". However I've a very slow algorithm for that so I hope I will solve it.

[quote]That's a great site. Currently I'm 99% genius on their rating system, only 1 problem missing from 158 problems.[/quote]We think we got the link from you somewhere.

We've solved 3 problems via brute force. We like reading the forum for each problem afterwards to see the really elegant solutions.

In our defense, we do use Berkeley Logo, so you end up with concise and easily read gems like this:

[code]make "i "1 make "s "0 while [ lessp :i "1000 ] [ if or equalp "0 remainder :i "3 equalp "0 remainder :i "5 [ make "s sum :s :i ] make "i sum :i "1 ] print :s[/code]:confused:

Which looks like it solves problem #1 in the list.
