Steven Strogatz: Whi Pi Matters

Our American colleagues celebrate today Pi Day, although, technically speaking, it is American Pi Day: for the rest of the world, today is 14/03/14. A brilliant article by Steven Strogartz in The New Yorker, a brief quote:

What distinguishes pi from all other numbers is its connection to cycles. For those of us interested in the applications of mathematics to the real world, this makes pi indispensable. Whenever we think about rhythms—processes that repeat periodically, with a fixed tempo, like a pulsing heart or a planet orbiting the sun—we inevitably encounter pi. There it is in the formula for a Fourier series: […]

Maria Droujkova: Multiplication Explorers Online Course

Multiplication Explorers Online Course

What’s so special about multiplication? To begin with, it is universal and therefore unavoidable. We all had to learn it. And our children will have to learn it too, in some shape or form. Here’s something else – the way you will help your children learn multiplication will mirror the way you learned it yourself, unless you take steps to change that. So how did you learn?

Did you spend hours repeating “the facts” with chants, flashcards, and seemingly endless drills? A lot of things have changed since we were children. There must be more effective ways of mastering multiplication! And there must be ways to make it relevant to our lives!

Let’s dig deeper. Do you remember how you felt studying the multiplication tables? For so many people we meet, the dislike and fear of math can be traced all the way back to their struggles to understand (and not just memorize) multiplication. Can we change this pattern so our children, approaching multiplication, feel not fear but curiosity, not anxiety but joy, not alienation but affinity? Can multiplication be more about smart play, rich mathematical thinking and usefulness everywhere in life?

This is what our Multiplication Explorers course is all about. It explores holistic approach to learning multiplication. Memorization based on smart number patterns is a part of it. The course also includes bridges between multiplication and natural world, as well as links to many virtual and imaginary worlds in books, music, technology, art, and games.

We invite you to boldly go beyond the familiar representations of multiplication such as skip counting and repeated addition, to explore many more meaningful, beautiful, and fun models. This course is a launch pad to adventures across the universe of multiplication.

Hamid Naderi Yeganeh: Mathematical drawings made from segments

A cardioid

This figure is closely related to a cardioid.

This image shows 1,000 line segments. For each \(i=1,2,3,\cdots,1000\) the endpoints of the \(i\)-th line segment are:

\[\left(\cos\left(\frac{2\pi i}{1000}\right), \sin\left(\frac{2\pi i}{1000}\right)\right)\]

and
 
\[\left(\cos\left(\frac{4\pi i}{1000}\right), \sin\left(\frac{4\pi i}{1000}\right)\right).\]

The Imitation Game Cryptography Competition

From Charles Walkden, University of Manchester:

Dear all,

The Imitation Game Cryptography Competition:  www.maths.manchester.ac.uk/cryptography_competition_the_imitation_game

`The Imitation Game‘ is a biopic of Alan Turing starring Benedict Cumberbatch in the lead role (also starring Keira Knightley, Charles Dance,…) and will be released in cinemas on Nov 14th.

The film’s distributors asked us to get involved in the publicity and promotion for the film by running a one-off on-line `Imitation Game Cryptography Competition‘, www.maths.manchester.ac.uk/cryptography_competition_the_imitation_game.

It’s free to enter and is open to everybody.  There are some great prizes for you to win: film posters signed by the cast, DVD bundles, soundtracks, etc,  The competition runs until 14th Nov.
Please can you spread the word to anyone and everyone (and feel free to take part yourself!).
PS:  The School’s annual `Alan Turing Cryptography Competition’ will run again from Jan 2015, with registration opening on 1st Dec.  Unlike the Imitation Game competition, this is only open to school children in Year 11 or below – but again please spread the word!
Andrew, Charles, Kees, Sebastian, Helen

BugFest 2014 Coloring Fractal

BugFest is a big annual celebration of insects and crustaceans at the North Carolina Museum of Natural Sciences, attracting some 35,000 visitors to its hands-on learning centers – for example, to explore fractals in nature at our table. We miss you already, BugFest friends, and hope to see you again next year! Huge thanks go to the amazing kids who liked our activities so much that they taught them to others. The two most popular activities at the BugFest were insect-themed coloring pages and origami.
