Dear Colleagues & Friends

 

With this first Math e-Newsletter of the year 2017, I'd like to wish everyone a happy mathematical year ahead.

 

1. HOMEPAGE UPDATES

 

My 'Downloadable Articles' Homepage at http://dynamicmathematicslearning.com/homepage4.html has been updated with the following new item:

1)      Enrichment for the Gifted: Generalizing Some Geometrical Theorems & Objects (my ICME 13 paper).

2)      mathematics/science cartoon and mathematics quote (at bottom of page)

 

My 'Dynamic Geometry Sketches' site has been updated with a neat solution by Johan Meyer in the Explorations for Students section:

1) Japanese Circumscribed Quadrilateral Theorem

 

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

 

a) Entries for the SA Mathematics Olympiad (SAMO) for Grades 8-12 organized by the South African Mathematics Foundation (SAMF) is closing this Fri, 3 February 2017. Last year more than 80 000 learners participated; so please consider entering as many learners as you can.

b) The SA Mathematics Challenge (SAMC) for Grades 4-7 will also run again this year, and has had entries in excess of 70 000.

For information about entering these competitions go respectively to these 2 sites:

SAMO: http://www.samf.ac.za/Default2.aspx

SAMC: http://www.samf.ac.za/Challenge.aspx

 

 

3. WEBSITES

 

a) The most common question students ask math teachers at every level is "When will I use math?" WeUseMath.org is a non-profit website that helps to answer this question. This website describes the importance of mathematics and many rewarding career opportunities available to students who study mathematics. Also provides some Teachers Resources and Links to Math Competitions.  Go to: http://weusemath.org/

 

b) Join the site https://www.academia.edu for free and read scholarly papers like "Algebraic thinking of grade 8 students in solving word problems with a spreadsheet" by Susana Carreira and "Mathematics education ideologies and globalization: Is mathematics discovered or invented?" by Paul Ernest.

 

c) Join the site https://www.researchgate.net/ for free and read scholarly articles about the teaching and learning of mathematics at all levels.

 

d) Celebrate PI day, March 14 (3.14) with these learning activities from the NCTM Illuminations website:

Grades 6–8 Unit: Apple Pi

Discover the ratio and meaning of pi.

Grades 9–12 Interactive: Pi Fight

Become comfortable using both radians and degrees with this fun game.

5. QUOTES TO PONDER

 

"If mathematics describes an objective world just like physics, there is no reason why inductive methods should not be applied in mathematics just the same as in physics." - Logician Kurt G̈odel (1906-1978) in 1951 Gibbs Lecture.

 

"The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities — perhaps the only one — in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there."  ― Karl Popper, Conjectures and Refutations: The Growth of Scientific Knowledge

 

"It seems to be one of the fundamental features of nature that fundamental physical laws are described in terms of a mathematical theory of great beauty and power, needing quite a high standard of mathematics for one to understand it. You may wonder: Why is nature constructed along these lines? One can only answer that our present knowledge seems to show that nature is so constructed. We simply have to accept it. One could perhaps describe the situation by saying that God is a mathematician of a very high order, and He uses very advanced mathematics in constructing the universe. Our feeble attempts at mathematics enable us to understand a bit of the universe, and as we proceed to develop higher and higher mathematics we can hope to understand the universe better."    - British physicist P.A.M. Dirac

 

 

6. LIGHTER SIDE

 

Proof by deception: "Now everyone turn your backs. . ."

 

Proof by supplication: "Oh please, let it be true."

 

Proof by poor analogy: "Well, it's just like adding fruit . . . "

 

Proof by avoidance: "This is so easy, let's skip it ..."

 

Proof by design: "If it's not true in today's math, invent a new system in which it is."

 

Proof by authority: "Well, Wolfram Mathematica says it's true, so it must be!"

 

Proof by intuition: "I just have this gut feeling. . ."

 

 

Geometrically yours

Michael
