New in SystemModeler

Our goal with SystemModeler is to provide a state-of-the-art environment for modeling, simulation—and analytics—that leverages the Wolfram technology stack and builds on the Modelica standard for systems description (that we helped to develop).

SystemModeler is routinely used by the world’s engineering organizations on some of the world’s most complex engineering systems—as well as in fields such as life sciences and social science. We’ve been pursuing the development of what is now SystemModeler for more than 15 years, adding more and more sophistication to the capabilities of the system. And today we’re pleased to announce the latest step forward: SystemModeler 5.

The Practical Business of Ontology: A Tale from the Front Lines

The Philosophy of Chemicals

“We’ve just got to decide: is a chemical like a city or like a number?” I spent my day yesterday—as I have for much of the past 30 years—designing new features of the Wolfram Language. And yesterday afternoon one of my meetings was a fast-paced discussion about how to extend the chemistry capabilities of the language.

At some level the problem we were discussing was quintessentially practical. But as so often turns out to be the case for things we do, it ultimately involves some deep intellectual issues. And to actually get the right answer—and to successfully design language features that will stand the test of time—we needed to plumb those depths, and talk about things that usually wouldn’t be considered outside of some kind of philosophy seminar.

Map Projections and the Center of the US

July 14, 2017 — Brian Wood, Technical Writer, Technical Communications and Strategy Group

Center of the United States

In 1918, the National Geodetic Survey (or NGS, at that time the United States Coast and Geodetic Survey) used its compiled geodetic data to compute the geographic center of the contiguous United States as 39°50′N 98°35′W. Their methodology—balancing a cardboard cutout of the lower 48 states at a point—was rudimentary but surprisingly effective, coming within 20 miles of modern estimates. A marker stands near the location (in the city of Lebanon, Kansas) to commemorate the historic calculation.

Books from around the (Wolfram) World!

July 7, 2017 — John Moore, Marketing and Technical Content Team Lead

We’re always excited to see what new things people have created using Wolfram technologies. As the broad geographical distribution of Wolfram Community contributors illustrates, people all over the world are doing great things with the Wolfram Language. In this vein, today we want to highlight some recent books written in languages other than English that utilize Wolfram technologies. From engineering to statistics, these books provide valuable information for those looking to dig a little deeper into scientific applications of the Wolfram Language.

Analyzing Social Networks of Colonial Boston Revolutionaries with the Wolfram Language

June 29, 2017 — Swede White, Media & Communications Specialist

Revolutionary social networks lead image

As the Fourth of July approaches, many in America will celebrate 241 years since the founders of the United States of America signed the Declaration of Independence, their very own disruptive, revolutionary startup. Prior to independence, colonists would celebrate the birth of the king. However, after the Revolutionary War broke out in April of 1775, some colonists began holding mock funerals of King George III. Additionally, bonfires, celebratory cannon and musket fire and parades were common, along with public readings of the Declaration of Independence. There was also rum.

Today, we often celebrate with BBQ, fireworks and a host of other festivities. As an aspiring data nerd and a sociologist, I thought I would use the Wolfram Language to explore the Declaration of Independence using some basic natural language processing.

Using metadata, I’ll also explore a political network of colonists with particular attention paid to Paul Revere, using built-in Wolfram Language functions and network science to uncover some hidden truths about colonial Boston and its key players leading up to the signing of the Declaration of Independence.

Create a Tracker to Analyze Gas Mileage Using Wolfram Tech

Completed reportPlot 3D animation

When I first started driving in high school, I had to pay for my own gas. Since I was also saving for college, I had to be careful about my spending, so I started manually tracking how much I was paying for gas in a spreadsheet and calculating how much gas I was using. Whenever I filled my tank, I kept the receipts and wrote down how many miles I’d traveled and how many gallons I’d used. Every few weeks, I would manually enter all of this information into the spreadsheet and plot out the costs and the amount of fuel I had used. This process helped me both visualize how much money I was spending on fuel and manage my budget.

Once I got to college, however, I got a more fuel-efficient car and my schedule got a lot busier, so I didn’t have the time to track my fuel consumption like this anymore. Now I work at Wolfram Research and I’m still really busy, but the cool thing is that I can use our company technology to more easily accomplish my automotive assessments.

Brain, Neurons, Cognition: Computational Neuroscience

June 6, 2017 — Keiko Hirayama, Wolfram|Alpha Developer, Wolfram|Alpha Scientific Content

Brain image and brain flow graph

As the next phase of Wolfram Research’s endeavor to make biology computable, we are happy to announce the recent release of neuroscience-related content.

The most central part of the human nervous system is the brain. It contains roughly 100 billion neurons that act together to process information, subdivided functionally and structurally into areas specialized for certain tasks. The brain’s anatomy, the characteristics of neurons and cognitive maps are used to represent some key aspects of the functional organization and processing abilities of our nervous system. Our new neuroscience content will give you a sneak peek into the amazing world of neuroscience with some facts about brains, neurons and cognition.

New Books on Applications of the Wolfram Language

June 2, 2017 — Michael Gammon, Blog Coordinator, Document and Media Systems

We’re always excited to see new books that illustrate applications of Wolfram technology in a wide range of fields. Below is another set of recently published books using the Wolfram Language to explore computational thinking. From André Dauphiné’s outstanding geographical studies of our planet to Romano and Caveliere’s work on the geometric optics that help us study the stars, we find a variety of fields served by Wolfram technology.

New in the Wolfram Language: Enhanced Derivatives

May 25, 2017 — Devendra Kapadia, Kernel Developer, Mathematica Algorithm R&D

Calculus mathematician timeline

Derivatives of functions play a fundamental role in calculus and its applications. In particular, they can be used to study the geometry of curves, solve optimization problems and formulate differential equations that provide mathematical models in areas such as physics, chemistry, biology and finance. The function D computes derivatives of various types in the Wolfram Language and is one of the most-used functions in the system. My aim in writing this post is to introduce you to the exciting new features for D in Version 11.1, starting with a brief history of derivatives.
