A movement is underway in the United States to reintroduce schools and families to freshly prepared meals. Last month, First Lady Michelle Obama introduced the “Let’s Move” campaign, an effort to raise awareness of and access to fresh food in schools and in our communities. The goal of the campaign is to eliminate childhood obesity within a generation. This Friday, Chef Jamie Oliver’s new television show Food Revolution will take us inside a few of America’s school cafeterias and classrooms in an effort to fulfill his wish to teach every child about food.

Wolfram|Alpha is already being used as a learning tool in schools to tackle subject areas such as math, science, social studies, and more. But did you know that Wolfram|Alpha contains a number of tools to help schools and families successfully start their own nutrition and wellness revolutions?

Imagine if students had the opportunity to compare the nutritional values of lunch options and make informed decisions before ever hitting the cafeteria. For example, students can go online to Wolfram|Alpha and compare grilled chicken breast to a corn dog. Wolfram|Alpha provides them with a nutrition label for each item, and shows a side-by-side comparison of nutritional values such as fats, proteins, and vitamins in each food option.

Saturday’s massive 8.8-magnitude earthquake in Chile has captured the attention and concern of the world community. The area continues to be plagued by dozens of smaller quakes including at least nine of magnitude 6.0 or higher.

Below is a timeline of earthquake activity in Chile over the last 72 hours. Wolfram|Alpha‘s earthquake data is updated every six minutes with information reported by the United States Geological Survey (USGS). The USGS reports activity within 30 minutes of most seismic events worldwide.

In addition to the map and timeline, the output shows the top three earthquakes (ranked in decreasing order of magnitude) within the past 72 hours, and clicking the “More” button will pull up information on the lower-magnitude shocks. Furthermore, you can see exact coordinates by clicking the “Show coordinates” button.

If you’re monitoring quake activity in Chile or other parts of the world, you will find Wolfram|Alpha useful for exploring a single event or series of events by time, location, and magnitude.

(The image below reflects activity within the 72 hours before this post was written; click the image for current information and further exploration.)

We’ve added a new feature that will come in handy for adding information from Wolfram|Alpha into your next blog post or presentation: you can now easily save results pods from Wolfram|Alpha as GIF images.

Here’s a quick walk-through to get you started. First, enter a query into Wolfram|Alpha, such as “1 cup of oatmeal + ½ cup of milk + 1 tsp of sugar“. You can then save results by right-clicking on the pod you want, then clicking on the “Generate image of output” icon that appears in the lower right corner of the popup pod.

One of the most rewarding aspects of working on Wolfram|Alpha is the support from everybody who wants to participate in our mission to make all systematic knowledge computable by everyone. Some help by submitting ideas for data sets or usability, or by reporting bugs; others are helping us achieve this goal as Wolfram|Alpha volunteer data curators. We’d like to take this opportunity to recognize a few of our volunteers and share highlights of the program.

Data curators are charged with identifying and collecting data for a specific subject area or region, and preparing the data to be incorporated into Wolfram|Alpha. There are many advantages to being a volunteer for Wolfram|Alpha compared to other online databases. First, because Wolfram|Alpha is in the early stages of its growth, there are plenty of opportunities to contribute to areas of most interest to you. Second, the data that volunteers curate is reviewed and verified with a member of the Wolfram|Alpha development team, so you don’t have to worry about your contribution being erased or altered by another user on the web. In addition, all volunteers receive a complimentary Mathematica license for the duration of their involvement.

Today we have a global network of over 240 volunteer data curators from over 50 countries, including Mexico, Colombia, Australia, France, Greece, United Arab Emirates, China, Malaysia, India, Egypt, and the United States. We’d like to introduce a few volunteers and share why they became involved in the project and what they hope to achieve.

Seth, a United States native residing in Austin, Texas, recently retired after 30 years of work in mathematics, physics, computer science, and statistics. Throughout his career he has contributed to an impressive number of projects in fields ranging from epidemiology to meteorology, social network analysis, and many more.

He became a Wolfram|Alpha Volunteer Data Curator shortly after the site’s launch in May 2009. Seth claims he got involved because of “ulterior motives,” stating, “The old saying says, ‘You learn something new every day.’ Through my work on the project, I wanted to see if I can learn two new things.”

This international traveler and avid reader says the amount of time he allocates to the project varies from week to week depending on what life brings. Thus far Seth has contributed to the project by gathering country data for New Zealand, and publication and distribution data for books. We asked Seth about the challenges he has encountered as a curator and he said, “One challenge that anyone working with ‘real world’ data has to deal with is the quality, currency, and availability of data. In this type of work, when I find a reliable, up-to-date, comprehensive source of information, I feel like a miner, after digging through tons of granite, finally encountering a vein of pure gold. I pick out every bit of useful information I can, then continue on through the granite. By the time I go from raw data, organize it into understandable information to submit for inclusion into the knowledge base, it has to be correct. If there is a choice between including data that could well be incorrect and leaving that data out, it should be left out until better data can be found.”

Saleh Penhos runs a knit clothing factory that produces graphic T-shirts in Mexico City, Mexico. He is also a self-professed fan of computers. Saleh says his computer skills are mostly self-taught but that he did study computer systems engineering in college.

Saleh became a volunteer after learning about Wolfram|Alpha’s mission. He says that he immediately fell in love with the project and saw volunteering as an opportunity to contribute to the data community. Thus far, Saleh has experienced no challenges. In fact, he says he enjoys searching for reliable information, and as a bonus he is exposed to new fields of knowledge. He currently spends about seven hours a week curating Mexico’s country and geographic data in addition to translating some information to the Spanish language.

Rohan Sehgal is a native of India, currently studying in Dubai, United Arab Emirates. Rohan’s goal of becoming a computer engineer led him to Wolfram|Alpha when he began using the site for help with differential and integral calculus. He said the benefits he received from Wolfram|Alpha led him to want to contribute to its growth.

We recently checked up with Rohan to find out what he was working on, and he said, “Currently I’m participating in a project for finding information on fictional characters in movies, serials, and books. But I have curated data involving languages, units of measurement, and facts and figures on countries as well. Being a curator takes anywhere between fifteen minutes to an hour’s work a week. Wolfram|Alpha is extremely supportive and has not only provided me with assistance at nearly all points of time, but also with the software to work on the same platform as them. All in all it has been a wonderful experience.” More »

Version 1.1 of the Wolfram|Alpha App for the iPhone & iPod is now available in the App Store. The new version includes a number of new features that continue to improve the app’s unique mobile Wolfram|Alpha experience. Perhaps its most iconic feature, the specialized keyboards that greet you when you first open the Wolfram|Alpha App, have been painstakingly constructed to ease the burden of entering queries, whether you’re converting from pounds to euros or computing a numerical value for the Weierstrass p-function . Our goal in creating these keyboards was to form families of characters that naturally occur together both in common use and in traditional mathematical applications. We also wanted mathematical expressions to look and feel natural to enhance usability and understanding. Version 1.1 has four specialized keyboards: the default keyboard, the “math” keyboard accessed by the right-shift key  , the “Greek” keyboard accessed by one press of the left-shift key , and the “symbol” keyboard accessed by a second press of the left-shift key.

To determine the optimal keyboard layout, we scoured Wolfram|Alpha’s server logs for the most commonly entered phrases that have characters with meaning in Wolfram|Alpha. Given that Wolfram|Alpha is built on Mathematica, one of its core strengths is advanced mathematics. True to form most of the commonly typed characters are related to math. For example, you would generally type the word “integrate” to compute an integral on the Wolfram|Alpha website. In the Wolfram|Alpha App you could simply type the  key on the math keyboard. The same is true for other symbols common in math, such as and . Specifying geometric shapes, such as a triangle, is straightforward as well.
