Dear Colleagues & Friends
Shortly after I sent out my previous Math e-Newsletter at the end of January this year, my desktop computer unfortunately completely crashed. In the process I unfortunately lost some files and e-mails, and it might be that some folks who requested to be added or removed from the mailing list were not. So please feel free to contact me again. Also note I am sending this mail from my g-mail account, which I don't check daily.

WebSketchpad:
My latest Dynamic Geometry Sketches all use WebSketchpad, which are more easily accessible across a range of platforms from cellphones to tablets as well as laptops and PC's without the need to constantly update Java, or to change your security settings.
2. SA MATHEMATICS OLYMPIAD
This year's SA Mathematics Olympiad (SAMO) had a record breaking number of almost 100 000 learners participating. Congratulations to all new learners (and their teachers and parents) who progressed to the third, final round - good luck!
3. IN MEMORIAM
It was with shock and sadness I learnt of the passing of Malcolm Swan from the University of Nottingham's Shell Centre for Mathematical Education, who died at the age of 64. His research work on the teaching and learning of modelling, graphs representing real-world situations, and diagnostic teaching was particularly influential around the world.

7. QUOTES TO PONDER
"... logical inferences are definitely productive in extending knowledge by virtue of bringing to light otherwise unsuspected connections." - Yehuda Rav (1999:10). Why do we prove theorems? Philosophae Mathematicae.
"Perhaps, though, there is another purpose to proof - as a testing ground for the stamina and ingenuity of the mathematician. We admire the conqueror of Everest, not because the top of Everest is a place we want to be, but just because it is so hard to get there." - Davis & Hersh (1983:369) in The Mathematical Experience.
"Were all proofs in mathematics routine, there would be a machine that could solve any problem; press a button and wait until the machine presents its answer. But it can be proved that no such machine can ever exist. Your first reaction to this fact of life might be despair, but do not be discouraged. Mathematics is not the realm of a few "magicians"; you are not expected to compete with Archimedes, Gauss, Hilbert, and Poincare'. Each of us is inventive to some degree; and the more one learns, the more proficient one becomes. In music, we can listen and thrill to the beauty of Bach, Mozart, and Beethoven. Even though we cannot compose the sonatas for unaccompanied violin, Don Giovanni, or the late quartets, we can still sing." - Joseph Rotman (1998: 15). Journey into Mathematics. London: Prentice-Hall.
8. LIGHTER SIDE
There was a statistician that drowned crossing a river... It was 3 feet deep on average.
An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third orders a third of a beer. The mathematical educated bartender bellows, "Get the hell out of here, are you trying to ruin me?"
Mathematic puns are the first sine of madness - Johann Von Haupkoph
Crazy Dictionary of Mathematical Terms:
Calculus - what a dentist scrapes from teeth.
Center of Mass - the Priest.
Centroid - a 100 year old nerd.
Chaos - Kmart.
Chord - a pile of wood.
Circle - the longest distance between any two points.
Circumference - a circuitous inference.
Coefficient - two heads are better than one.
Cylinder - Budweiser.
