## Wild About Math blogs 4/22/11

Welcome to another edition of Wild About Math blogs!

I'm about to start a new blog about the intersection of Math+kids+exploration+programming+Mathematica.

I’m about to start a blog about programming with Mathematica as a way for kids (and adults) to get engaged with Math. I’m pretty new to Mathematica and I find myself getting stuck with some of the basics (which will make the new blog all the more valuable.)

If you have experience with Mathematica and can help me with writing some simple animations I would be incredibly grateful and, of course, I will acknowledge you in the blog and (if you like) I’ll link to your site.

In the new blog I’ll be writing how-to articles where I dissect some simple Mathematica code and show readers how to do neat explorations.

If you can help please drop me an email at

## Playing with Mathematica is live

This morning I launched a new site, Playing with Mathematica. For those of you who, like me, are new to Mathematica I believe you will enjoy the site. (I'm not calling it a blog because my intent is to produce in depth how-to notebooks and essays on topics related to exploring math with Mathematica. I'm not expecting it to have the tone of a blog.)

Wild About Math! will continue to live on although by the end of next month I'll stop doing the weekly Wild About Math bloggers! series and I'll go back to the sporadic postings I've been doing for some time.

I invite you to come check out the new site and, if it catches your fancy, subscribe in a reader or via email.

## I’m famous!

The local Santa Fe newspaper ran an article about my monthly Math gatherings.

... I read about some guy who thought it was possible to make math "fun and accessible." He started a blog, Wild About Math!, and last fall he began hosting a math group the third Wednesday of each month at the Santa Fe Complex (a place where brainy people work with math to create some incredible, even useful, things).

Welcome to the April 8th edition of Wild About Math Bloggers!

What's special about Algebra II? The Washington Post reports that ...

Of all of the classes offered in high school, Algebra II is the leading predictor of college and work success, according to research that has launched a growing national movement to require it of graduates.

Try your hand at this problem that lends itself to proof by induction.

It is known that

is an integer number. Prove that is also an integer number for any integern.Discussion and hints: Use mathematical induction. First square the given integer number to show that is also an integer number, thus proving the statement for

n= 2 .

## 80 pencils

Check out the great pictures in this blog post by Cory Poole at An Ocean of Knowledge an Inch Deep.

It's the middle of April and this next week all students at University Preparatory School, where I teach, will be taking the California standardized tests. So I decided to design and build a sculpture that I'm calling "Standardized Testing And Reporting" or "STAR", which is what the California testing program is named. The sculpture is made up of 80 pencils and is held together with a variety of glues.

Welcome to April!

The 9th Mathematics and Multimedia Blog Carnival is hosted at Virtual Math Tutor. Check out this perpetual motion waterwheel I discovered at the Carnival:

Math Teachers at Play 36 is published at Math Hombre.

Check out the article (and video below) of a 12-year old physics genius. The article title refers to the boy as autistic but, if you read the article, you'll learn that the boy has Asperger's Syndrome. HUGE difference. (Hat tip to Shecky.)

## TI introduces new color-display TI-Nspire CX

TI has a new color CAS (computer algebra system) handheld learning device!

From the Press Release:

DALLAS, Feb. 25, 2011 /PRNewswire/ -- In its quest to support math and science educators in achieving learning goals for their students, Texas Instruments rolls out its Nspired Learning solution with the introduction of the new color-display TI-Nspire™ CX handheld. With the Nspired Learning solution, teachers are able to build their own interactive and engaging math and science classrooms.

The TI-Nspire CX handheld is the cornerstone of the Nspired Learning solution. The TI-Nspire CX handheld offers a set of fully integrated tools that allow dynamic links among multiple representations of a problem. The color display enables students to better observe patterns and make connections between math and science concepts and real-world learning. With the TI-Nspire CX and TI-Nspire CAS handhelds' new 3D graphing capabilities, students can explore concepts from multiple points of view to develop deeper conceptual understanding.

Welcome to Spring!

Conrad Wolfram writes about how the usability of the Wolfram Demonstration site has been greatly improved:

Our "knowledge app" site demonstrations.wolfram.com was completely redesigned to use the inline Mathematica 8 or free Wolfram Player plug-in rather than having to open a separate window (alongside various other changes).

This apparently small plug-in change makes a big usability difference and by the same token, it changed the site workflow quite a bit. It also required the latest version of Player--just releasing too--and itself quite a feat of engineering.

Division by Zero has an exploration of Albrecht Dürer’s ruler and compass constructions.

These constructions are definitely Geogebra-worthy.
