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!

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.

“Measurement”, by Paul Lockhart

From Harvard University Press:

For seven years, Paul Lockhart’s A Mathematician’s Lament enjoyed a samizdat-style popularity in the mathematics underground, before demand prompted its 2009 publication to even wider applause and debate. An impassioned critique of K–12 mathematics education, it outlined how we shortchange students by introducing them to math the wrong way. Here Lockhart offers the positive side of the math education story by showing us how math should be done.Measurement offers a permanent solution to math phobia by introducing us to mathematics as an artful way of thinking and living.

In conversational prose that conveys his passion for the subject, Lockhart makes mathematics accessible without oversimplifying. He makes no more attempt to hide the challenge of mathematics than he does to shield us from its beautiful intensity. Favoring plain English and pictures over jargon and formulas, he succeeds in making complex ideas about the mathematics of shape and motion intuitive and graspable. His elegant discussion of mathematical reasoning and themes in classical geometry offers proof of his conviction that mathematics illuminates art as much as science.

Lockhart leads us into a universe where beautiful designs and patterns float through our minds and do surprising, miraculous things. As we turn our thoughts to symmetry, circles, cylinders, and cones, we begin to see that almost anyone can “do the math” in a way that brings emotional and aesthetic rewards. Measurement is an invitation to summon curiosity, courage, and creativity in order to experience firsthand the playful excitement of mathematical work.

 

 

Moebius Noodles: Adventurous Math for the Playground Crowd

A highly unusual and original book for parents of young children, written by Yelena McManaman, Maria Droujkova, and Ever Salazar, and published under Creative Commons Attribution-NonCommercial-ShareAlike license. From promotional material:

 How do you want your child to feel about math? Confident, curious and deeply connected? Then Moebius Noodles is for you. It offers advanced math activities to fit your child’s personality, interests, and needs.

Can you enjoy playful math with your child? Yes! The book shows you how to go beyond your own math limits and anxieties to do so. It opens the door to a supportive online community that will answer your questions and give you ideas along the way.

Learn how you can create an immersive rich math environment for your baby. Find out ways to help your toddler discover deep math in everyday experiences. Play games that will develop your child’s sense of happy familiarity with mathematics.

A five-year-old once asked us, “Who makes math?” and jumped for joy at the answer, “You!” Moebius Noodles helps you take small, immediate steps toward the sense of mathematical power.

You and your child can make math your own. Together, make your own math!

Moebius Noodles run a crowd-sourced project: translation of the book in  languages ranging from French to Turkish. Please join here!
