Announcing the Mathematica Summer Camp 2012

Are you looking for a great way to spend your summer? We are happy to announce the Mathematica Summer Camp 2012! Held at Curry College in Milton, Massachusetts, students will have the opportunity to learn Mathematica’s language, apply their skills in other disciplines, and program their very own Wolfram Demonstrations! Students will also work individually and in groups to hone their Mathematica skills.

A Preview of CDF on iPad

For 22 years, Wolfram Research has been developing technology to allow subject matter experts to bring their ideas and documents to life with interactivity. This week, as part of his keynote at the O'Reilly Tools of Change for Publishing Conference, Theodore Gray, Co-founder of Wolfram Research and Founder of Touch Press, gave the first demonstration of how we're bringing the full power of our publishing systems to mobile devices. Here's a video excerpt of his announcement of the Computable Document Format (CDF) for iPad:

Apply for the 10th Annual Wolfram Science Summer School

The Wolfram Science Summer School (formerly the NKS Summer School) is now accepting applications for its 10th season, to be held June 25–July 13, 2012, at Curry College in Milton, Massachusetts, United States. We are looking for highly motivated individuals who want to get involved with original research at the frontiers of science. Our participants come from diverse backgrounds but share a common passion to discover and explore cutting-edge ideas. Over the past ten years, participants have included graduate students, undergraduates, professors, industry professionals, artists, and even a few exceptional high-school students.

Launching a Democratization of Data Science

It’s a sad but true fact that most data that’s generated or collected—even with considerable effort—never gets any kind of serious analysis. But in a sense that’s not surprising. Because doing data science has always been hard. And even expert data scientists usually have to spend lots of time wrangling code and data to do […]

Announcing Wolfram|Alpha Pro

Today I’m excited to be able to announce the launch of Wolfram|Alpha Pro—the biggest single step in the development of Wolfram|Alpha since its original introduction. Over the two and a half years since we first launched, Wolfram|Alpha has been growing rapidly in content and capabilities. But today’s introduction of Wolfram|Alpha Pro in effect adds a […]

Happy 10*9*8+7+6-5+4*321 !

I was amazed to see this tweet from our friends at the Museum of Mathematics:

10*9*8+7+6-5+4*321Happy New Year!

— Museum of Math (@MoMath1) January 3, 2012 A quick check with Mathematica verified that, yes indeed, 10*9*8+7+6-5+4*321 = 2012. Wow! How in the world did anyone discover that rare factoid? And how long will it be until another year arrives that can be similarly expressed? That's the sort of question that's so easy to answer with Mathematica that I couldn't not have a look. It turns out that what seemed to me like a rare jewel is as common as dirt. In fact, there is only one year in the next 100 that can't be expressed by interspersing +, -, *, /, or nothing between the numbers in order from 10 to 1! In subsequent correspondence with George Hart, the museum's Chief of Content, he told me that he learned the idea from Hans Havermann, who wrote about it in a blog post last year. I've discovered what he had up his sleeve: abundant computing.

C and a Box of Chocolates: Video Presentations from the Wolfram Technology Conference 2011

Tips for analyzing your social networks with Mathematica, workshops for publishing with CDF, real-world solutions for your financial applications—these are just a few of the many highlights from the Wolfram Technology Conference 2011. If you missed a talk or weren't able to attend, we've now made videos of select presentations available on the Presentations and Talks section of the conference website.

The Wolfram Education Portal Is Here!

Teachers, are you looking for a new way to integrate technology into your classroom? How about through a dynamic textbook or pre-generated lesson plans? Students, are you looking for some extra help or practice in your classes? How about using interactive demonstrations and widgets to help understand the concepts you are learning? The Wolfram Education Portal is the answer for students and teachers alike! We are happy to announce the launch of the free Beta version of the Wolfram Education Portal. The portal comes equipped with a dynamic and interactive textbook, lesson plans aligned to the common core standards, and many other supplemental materials for your courses, including Wolfram Demonstrations, widgets, and videos. The Education Portal currently contains full materials for Algebra and partial materials for Calculus, but will continue to grow and improve with your comments and feedback.

The Longest Word Ladder Puzzle Ever

UPDATE: The solution to the puzzle and more comments from Jon have been added at the bottom of the post. On the long flight to the recent Wolfram Technology Conference, I ended up on the puzzle page of a newspaper. My attention was drawn to a word ladder puzzle, where you must fill in a sequence of words from clues, but each word differs from the previous by only a single letter. Here, for example, is a simple puzzle already solved:
best from a position of superiority or authority
bast strong woody fibers obtained especially from the phloem of from various plants
bash a vigorous blow
bath a vessel containing liquid in which something is immersed (as to process it or to maintain it at a constant temperature or to lubricate it)
math a science (or group of related sciences) dealing with the logic of quantity and shape and arrangement
I wasn't going to do a blog entry on this, as it is a very similar task to my "Exploring Synonym Chains" post that I wrote some time ago, but that changed with a chance conversation at the (excellent) Technology Conference. Proving that one never stops learning, Charles Pooh, one of our graph theory developers, pointed out to me that my synonyms item could have been done much better. I had broken one of the very rules that I wrote about in my "10 Tips for Fast Mathematica Code" entry—"Use built-in functions." I had effectively re-implemented the built-in Mathematica commands GraphPeriphery and GraphDiameter. So, armed with these two new functions, let's find the longest word ladder puzzle that can be made using Mathematica's English dictionary.
