I wanted to build a simple web application for manipulating and exporting Pythagoras trees to make posters and desktop wallpaper, and so I turned to the new features of webMathematica 3.

webMathematica is a web application framework released by Wolfram Research. It allows users to write web pages using Mathematica, seamlessly integrating Mathematica code with HTML and JavaScript.

webMathematica 3, the new version released on September 15, introduces several new features such as a web version of the popular Manipulate command and a way to evaluate Mathematica code asynchronously, without delaying page loading.

Longtime Mathematica user Flip Phillips recently sent us this tremendously amusing error message generated by Mathematica. Much as you might think when stumbling upon a pickup truck hanging from a tree, your first reaction is probably, “How does something like that even happen??”

I have taught collegiate mathematics for more than 20 years and have used Mathematica for 15 or so of these years to explore, learn, and teach. For the last eight years Mathematica has been my primary tool to write all of my exams, handouts, letters, reports, papers, presentations, and even a complete electronic textbook. New features introduced recently have been revolutionary in the teaching and learning environment and make possible the creation of materials that integrate text, typeset mathematics, and interactive figures, which can be created efficiently and used effectively in ways not possible with other software tools.

For faculty and students to benefit from using Mathematica in the teaching and learning process, they must be able to use Mathematica sufficiently well to remain focused on course concepts and not become frustrated by the technology. Without question, the main challenge I face teaching new users how to use Mathematica is helping them master the task of creating syntactically correct commands, followed closely by the challenge of teaching how to use Mathematica to write rich documents that combine text, typeset mathematics, and figures.

When the use of technology gets in the way of the teaching, learning, and writing about content, which should remain the focus of academic learning, then all involved in the teaching and learning process experience frustration! If enough example commands are provided, if the ways of Mathematica are carefully explained, and if patient help is readily available, then some new users are able work their way up the learning curve and reach a point where they can focus on the subject matter and are able to comfortably use Mathematica to explore, learn, teach, and write about the concepts. Members of this group are often able to independently deepen their understanding and use of Mathematica by relying on the Wolfram Mathematica Documentation Center and other resources; but not enough new users reach this level of Mathematica knowledge and thus do not experience firsthand the marvelous capabilities of Mathematica to explore, investigate, learn, teach, and write about interesting ideas!

In the middle of last year, we finished our decade-long project to reinvent Mathematica, and we released Mathematica 6.

We introduced a great many highly visible innovations in Mathematica 6—like dynamic interactivity and computable data. But we were also building a quite unprecedented platform for developing software.

And even long before Mathematica 6 was released, we were already working on versions of Mathematica well beyond 6.

And something remarkable was happening. There’d been all sorts of areas we’d talked about someday being in Mathematica. But they’d always seemed far off.

Well, now, suddenly, lots of them seemed like they were within reach. It seemed as if everything we’d built into Mathematica was coming together to make a huge number of new things possible.

All over our company, efforts were starting up to build remarkable things.

It was crucial that over the years, we’d invested a huge amount in creating long-term systems for organizing our software development efforts. So we were able to take those remarkable things that were being built, and flow them into Mathematica.

And at some point, we realized we just couldn’t wait any longer. Even though Mathematica 6 had come out only last year, we had assembled so much new functionality that we just had to release Mathematica 7.

So 18 months after the release of Mathematica 6, I’m happy to be able to announce that today Mathematica 7 is released!

Today is an important anniversary for me and our company.

Twenty years ago today—at noon (Pacific Time) on Thursday, June 23, 1988—Mathematica 1.0 was officially launched.

Much has changed in the world since then, particularly when it comes to computer technology.

But I’m happy to be able to say that Mathematica still seems as modern today as it did back then when it was first released. And if you take almost any Mathematica 1.0 program from 20 years ago, it’ll run without change in the latest Mathematica 6.0 today.

From the beginning, I had planned Mathematica for the long term. I wanted to build a system that could capture the essence of computation, and apply it wherever that became possible.

I spent great effort to get the fundamentals right—and to build the system on principles that would endure.

And looking back over the past two decades it’s satisfying to see how well that has worked out.

Many new features in Mathematica are manifested in new functions with definite names, but some are not so prominent. You might miss one of the new features that I implemented for Mathematica 6.0.2—but it’s really useful, and so I thought I’d write about it here.

Let’s say you have a plot, or some other kind of graphic. You see something in the graphic—some special point—and you want to know where that is, what its (x, y) coordinates are.

In earlier versions of Mathematica, there were primitive ways to find this out. Now in Mathematica 6.0.2 there’s a nice, clean, general way to do it.

Open the Drawing Tools palette (from the Graphics menu, or by typing CTRL-d or CTRL-t). Choose the “Get Coordinates” tool at the upper right.

In my ten years at Wolfram Research, I’ve never seen so much software development activity. In the middle of last year, we had our biggest launch in a decade: Mathematica 6. Now there’s a huge pipeline of new development underway.

Some people are working on Mathematica 7; some people on Mathematica 8. We’re developing major new frameworks and we’re adding boatloads of new functions. But we’re also continuing to polish and strengthen everything that’s already in Mathematica.

We brought out Mathematica 6.0.1 last summer to add a variety of improvements that didn’t make it into 6.0.0. And we’ve now accumulated enough improvements that we’ve decided to release 6.0.2—which is being sent to Premier Service customers as of today.

As someone who works with university software groups to maintain Mathematica site licenses, I’m not surprised that Windows Vista compatibility is such a common topic of conversation. After all, this is the season for setting up computer labs for the upcoming academic year, and Windows is quite the popular platform.

What does surprise me is the tone of these conversations. The questions during Vista testing started pouring in during the spring and fall semesters, and continued this summer.

Inquiries have a slightly weary, mildly suspicious tone and start with questions like, “What’s the story with Mathematica on Vista?” Or, “When will Mathematica be compatible with Vista, and what limitations should we keep in mind?” A few schools even asked the exact same questions about compatibility twice in consecutive weeks!

Clearly a complicated answer is expected here.

But the answer, for Mathematica at least, has been very simple since Vista’s early-spring release.

We can’t emphasize enough how important colors are in scientific visualization. Colors can convey the information which cannot be represented by geometry only. Sometimes, the data is just unreadable without proper colors in place. Most of all, colors can make graphics and plots more attractive and appealing.

In previous versions of Mathematica, it was not always easy to pick the right colors or color functions. Probably, you would end up playing with the values of RGBColor or Hue, which can be both tedious and time consuming.

During the development of Mathematica 6, we committed to change this situation. First off, we made–among dozens of newly added controls–a few specifically dedicated to color input.

Wolfram Research is a place where “eating your own dogfood” is part of the culture. Most of us use Mathematica for our routine office administration tasks, documents, presentations, sales forecasting, etc.

I have been using Mathematica to analyze international sales data for 15 years now. It was through this activity that I think I can stake the claim to being the first real practical professional user of the new CountryData function.

It was time to present an analysis of sales figures at our annual Wolfram Reseller Conference in April to help our distributors understand where they are doing well and where they need to improve.

Comparing sales is difficult when one distributor has a large territory like Germany, and another a relatively small one like Romania. A couple of years ago, I started using economic gross domestic product (GDP) of the territory as a scale, but it is a pretty blunt tool–one might expect a small industrialized economy to outperform a large agricultural one.

This year, a new tool was in my hands: Mathematica 6.
