Wolfram Technology Conference 2014

October 31, 2014 — Wolfram Blog

Wolfram technology users from around the world gathered in Champaign, Illinois, our headquarters, October 21–24, for another successful Wolfram Technology Conference. Attendees got access to the latest information about our emerging technologies and gained insights from colleagues who shared innovative ways of using Wolfram technologies.


The conference kicked off with a keynote by Stephen Wolfram, and then rolled right into the other 125 scheduled talks. Also featured were a connected devices playground, “Meet-Ups,” social/networking events, small group meetings, roundtable discussions, and tours of Wolfram and the Blue Waters supercomputer at the University of Illinois.

Calling All Goblins: Tweet-a-Program Halloween Code Challenge

October 27, 2014 — Wolfram Blog

Halloween is quickly approaching, and to help you gear up for trick-or-treating, costume parties, and pumpkin carving, we’re issuing another Tweet-a-Program Code Challenge! This time, instead of spaceships and planets, we want you to tweet us your spookiest Halloween-themed lines of Wolfram Language code. We’ll then use the Wolfram Language to randomly select three winning tweets (and a few of our favorites) to pin, retweet, and share with our followers. Winners will also be awarded a free Wolfram T-shirt!

Take some inspiration from these examples, while you come up with your creepy codes:

Wolfram Data Summit 2014

October 22, 2014 — Wolfram Blog

This year’s Wolfram Data Summit brought together innovators in data science, creators of connected devices, and leaders of major data repositories for two days of high-level discussion about challenges and opportunities facing the worldwide data community.

This annual Summit offers an exclusive group of thought leaders an opportunity to meet and share insights into new and ongoing projects. But in light of the high caliber and exceptionally broad interest of this year’s presentations—and for the first time ever—we are sharing videos of the Summit presentations with the public, including the keynote from Stephen Wolfram, CEO of Wolfram Research and creator of Wolfram|Alpha.

October 21, 2014 — Ed Pegg Jr, Editor, Wolfram Demonstrations Project

For today’s magic show:
A century ago,
Martin Gardner was born in Oklahoma.
He philosophized for his diploma.
He wrote on Hex and Tic-Tac-Toe.
The Icosian game and polyomino.
Flexagons from paper trim,
Samuel Loyd, the game of Nim.
Digital roots and Soma stairs,
mazes, logic, magic squares.
Squaring squares, the golden Phi.
Solved the spider and the fly.
Packing circles (with corrections),
ellipses, pi, and conic sections.

Summer Internships

October 16, 2014 — Jenna Giuffrida, Content Administrator, Technical Communications and Strategy Group

Summer has drawn to a close, and so too have our annual internships. Each year Wolfram welcomes a new group of interns to work on an exciting array of projects ranging all the way from Bell polynomials to food science. It was a season for learning, growth, and making strides across disciplinary and academic divides. The Wolfram interns are an invaluable part of our team, and they couldn’t wait to tell us all about their time here. Here are just a few examples of the work that was done.

First Tweet-a-Program Code Challenge: Space Week

October 7, 2014 — Wolfram Blog

In honor of World Space Week and this year’s theme of satellite navigation, “Space: Guiding Your Way,” we’re issuing a Tweet-a-Program Code Challenge focused on anything to do with space and getting there. You tweet us your “space-iest” line(s) of Wolfram Language code, and then we’ll use the Wolfram Language to randomly select three winning tweets (plus a few favorites) to shower with retweets, pin or post to our wall, and receive a free Wolfram T-shirt!

Any space-themed submissions tweeted to us @wolframtap all day Thursday and Friday (12am PDT Thursday, October 9 through 11:59pm PDT Friday, October 10) will be eligible to win. To not waste needed code space, no hashtag is required with your original submission, but we encourage you to share your results by retweeting them with hashtag #wsw2014 and #tapspaceweek.

In addition to satellite path tracking and real-time analysis, the Wolfram Language gives you access to all sorts of entities, formulas, and other functionality for astronomical computation and coding—from supernovas, comets, and constellations to the Sun, deep space, and other galaxies.

Maybe you want to remix the planets and their colors, as Stephen Wolfram did in one of his first Tweet-a-Program tweets:

The Nobel Prize in Physics

October 1, 2014 — Richard Asher

The Nobel Prize in Physics ceremony is upon us once again! With the 2014 winner set to be revealed in Stockholm next week, we at Wolfram got to wondering how many of the past recipients have been Mathematica users.

We found no less than 10 Nobel Prize–winning physicists who personally registered copies of Mathematica. That’s at least one in every eight Physics laureates since 1980! And anecdotal evidence suggests that nearly every Nobel laureate uses Mathematica through their institution’s site license.

Modeling Aircraft Flap System Failure Scenarios with SystemModeler

September 29, 2014

Have you heard about the Boeing 747 Dreamlifter that flew to the wrong airport and was forced to land on too short of a runway? Luckily, that story had a happy ending, and no passengers were hurt. Still, it is a potentially dangerous scenario when the landing distance required (LDR) is longer than the runway, and there are other possible reasons for such a situation besides a pilot gone astray.

One potential cause of such a scenario is a flap system failure. Flaps are hinged devices located on the trailing edges of the wings, where their angular position can be adjusted to change the lift properties of the plane. For example, suitably adjusting the flap position can enable the plane to be flown at a lower speed while maintaining its lift, or allow it to be landed with a steeper angle of descent without any increase in speed. One of several resulting advantages is that the LDR becomes shorter. This makes me wonder: Could a small flap failure increase the LDR so much that the assigned runway is suddenly too short?

To answer such a question, you have to understand the effects that a failure on a component level have at a system level. How will the control system react to it? Can we somehow figure out how to detect it during a test procedure? Can we come up with a safety procedure to compensate for it, and what happens if the pilot or maintenance personnel for some reason fail to follow that procedure?

Presentations Available from Wolfram Experts Live: New in Mathematica 10

September 24, 2014 — Jamie Peterson, Technical Programs Manager

Following one of our most anticipated releases to date, we hosted the virtual workshop Wolfram Experts Live: New in Mathematica 10 to give the Wolfram community the details on this latest version of our flagship product Mathematica.

Mathematica 10

A dozen Wolfram experts and Mathematica developers came together at our headquarters—both in person and remotely via online connections—to take turns showing off new advances in usability, algorithmic functionality, and integration with the Wolfram Cloud. Presenters participated in a live Q&A with the online audience, and in turn were able to hear from Mathematica users and enthusiasts.
