Exploring Exoplanet Systems with the Wolfram Language

Exoplanets are currently an active area of research in astronomy. In the past few years, the number of exoplanet discoveries has exploded, mainly as the result of the Kepler mission to survey eclipsing exoplanet systems. But Kepler isn't the only exoplanet study mission going on. For example, the TRAnsiting Planets and PlanetesImals Small Telescope (TRAPPIST) studies its own set of targets. In fact, the media recently focused on an exoplanet system orbiting an obscure star known as TRAPPIST-1. As an introduction to exoplanet systems, we'll explore TRAPPIST-1 and its system of exoplanets using the Wolfram Language.

Launching the Wolfram Data Repository: Data Publishing that Really Works

After a Decade, It’s Finally Here! I’m pleased to announce that as of today, the Wolfram Data Repository is officially launched! It’s been a long road. I actually initiated the project a decade ago—but it’s only now, with all sorts of innovations in the Wolfram Language and its symbolic ways of representing data, as well […]

Walking the Dog: Neural Nets, Image Identification and Geolocation

It's National Pet Day on April 11, the day we celebrate furry, feathered or otherwise nonhuman companions. To commemorate the date, we thought we'd use some new features in the Wolfram Language to map a dog walk using pictures taken with a smartphone along the way. After that, we'll use some neural net functions to identify the content in the photos. One of the great things about Wolfram Language 11.1 is pre-trained neural nets, including Inception V3 trained on ImageNet Competition data and Inception V1 trained on Places365 data, among others, making it super easy for a novice programmer to implement them. These two pre-trained neural nets make it easy to: 1) identify objects in images; and 2) tell a user what sort of landscape an image represents.

How to Use Your Smartphone for Vibration Analysis, Part 2: The Wolfram Cloud

Vibration measurement is an important tool for fault detection in rotating machinery. In a previous post, "How to Use Your Smartphone for Vibration Analysis, Part 1: The Wolfram Language," I described how you can perform a vibration analysis with a smartphone and Mathematica. Here, I will show how this technique can be improved upon using the Wolfram Cloud. One advantage with this is that I don't need to bring my laptop.

The R&D Pipeline Continues: Launching Version 11.1

A Minor Release That’s Not Minor I’m pleased to announce the release today of Version 11.1 of the Wolfram Language (and Mathematica). As of now, Version 11.1 is what’s running in the Wolfram Cloud—and desktop versions are available for immediate download for Mac, Windows and Linux. What’s new in Version 11.1? Well, actually a remarkable […]

Analyzing and Translating an Alien Language: Arrival, Logograms and the Wolfram Language

If aliens actually visited Earth, world leaders would bring in a scientist to develop a process for understanding their language. So when director Denis Villeneuve began working on the science fiction movie Arrival, he and his team turned to real-life computer scientists Stephen and Christopher Wolfram to bring authentic science to the big screen. Christopher specifically was tasked with analyzing and writing code for a fictional nonlinear visual language. On January 31, he demonstrated the development process he went through in a livecoding event you can watch on YouTube.

Meet the Authors of Hands-on Start to Wolfram Mathematica, Second Edition

Jeremy Sykes: To celebrate the release of Hands-on Start to Wolfram Mathematica and Programming with the Wolfram Language (HOS2), now in its second edition, I sat down with the authors. Working with Cliff, Kelvin and Michael as the book's production manager has been an easy and engaging process. I'm thrilled to see the second edition in print, particularly now in its smaller, more conveniently sized format.
