3D-Printed Jewelry Made with the Wolfram Language Showcases the Beauty of Mathematics
February 15, 2021 — Christopher Hanusa, Guest Author
I enjoy turning mathematical concepts into wearable pieces of art. That’s the idea behind my business, Hanusa Design. I make unique products that feature striking designs inspired by the beauty and precision of mathematics. These pieces are created using the range of functionality in the Wolfram Language. Just in time for Valentine’s Day, we recently launched Spikey earrings in the Wolfram Store, which are available in rose gold–plated brass and red nylon. In this blog, I’ll give a look under the hood and discuss how an idea becomes a product through the Wolfram Language.
Step-by-Step Math Tools in Wolfram|Alpha Help Your Chemistry Course Prep
February 12, 2021 — Becky Song, Wolfram|Alpha Scientific Content
Math is one of the main things that deters students from wanting to learn more about chemistry. Being a chemical engineering student, I understand this, especially for students who just have to get chemistry out of the way as a general education requirement. Essentially, step-by-step solutions are like your own on-demand math tutor: in addition to calculating the answer, Wolfram|Alpha shows you how it got there. Here are six important math skills that you will definitely use on a regular basis in your chemistry class and how they relate to different chemistry concepts.
Wolfram Certifications for Students, Professionals and Everyone in Between
February 11, 2021 — Jamie Peterson, Senior Training & Online Learning Manager, Wolfram U
Over a thousand new individual Wolfram Certifications were awarded in 2020 since the launch of new and updated online interactive courses and Daily Study Groups from Wolfram U. Students and professionals around the world have developed their skills and demonstrated proficiency in Wolfram technologies, as well as several topic-specific applications. We’re excited to now offer expanded achievement opportunities for certification in more areas and more levels.
Classifying Cough Sounds to Predict COVID-19 Diagnosis

Sound classification can be a hard task, especially when sound samples have small variations that can be imperceptible to the human ear. The use of machines, and recently machine learning models, has been shown to be an effective approach to solving the problem of classifying sounds. These applications can help improve diagnoses and have been a topic of research in areas such as cardiology and pulmonology. Recent innovations such as a convolutional neural network identifying COVID-19 coughs and the MIT AI model detecting asymptomatic COVID-19 infections using cough recordings show some promising results for identifying COVID-19 patients just by the sound of their coughs. Looking at these references, this task may look quite challenging and like something that can be done only by top-notch researchers. In this post, we will discuss how you can get very promising results using the machine learning and audio functionalities in the Wolfram Language.

Explore the contents of this article with a free Wolfram System Modeler trial.
System dynamics (SD) is a very powerful and flexible modeling paradigm, ideally suited to tackle strategic business, economics and public policy issues. Some years ago, Guido Wolf Reichert, management consultant and developer for BSL Management Support, Germany, stumbled into problems while modeling the public transport system in a German metropolis. He had reached the technical limits of the established SD software. While looking for alternatives, he discovered Wolfram System Modeler.
Project-Based Life Skills from Wolfram’s Emerging Leaders Program
January 26, 2021 — Rory Foulger, Instructional Designer & Technologist, Outreach & Communications
In the days of online learning and remote work, students are gaining valuable skills to help them navigate their education. With new needs for greater independence in their learning journeys, better time management and finding communities in unexpected places, students are already encountering important lessons. Student-centered events like the Wolfram Emerging Leaders Program help foster success in the workplace and in life, no matter what happens in the world.
The Advention of Coding: Advent of Code Solutions in the Wolfram Language
January 21, 2021 — Philip Maymin, Guest Author
Editor’s note: The following post is based on the 2020 Advent of Code challenge, “an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like.” Guest author Philip Maymin delves into why he chose to use the Wolfram Language to solve these queries with a how-to on learning the language.
How We Navigated a Hybrid Remote Learning Environment Using Wolfram Technology
January 14, 2021 — Timothy Newlin, Guest Author
The past year of learning ushered in a variety of new experiences for instructors and students alike, and the United States Military Academy at West Point was no exception. In addition to masks in the classroom, reduced class sizes to allow for social distancing, rigorous testing and tracing efforts, and precautionary remote video classes, we have also needed to adjust aspects of our teaching styles. While such adjustments were voluntary, to enhance the discussion I chose to teach several lessons outside under large white tents and even in stadium bleachers to safely enable larger conversations with my cadets. Sometimes this meant carrying a large whiteboard with a tripod out to the stadium. At other times it meant putting quiz-style questions on a website so that students could submit answers via forms that were easier to grade while allowing everyone to work at a safe distance on individual devices.
Deploy a Neural Network to Your iOS Device Using the Wolfram Language
January 7, 2021 — Jofre Espigule-Pons, Machine Learning
Today’s handheld devices are powerful enough to run neural networks locally without the need for a cloud server connection, which can be a great convenience when you’re on the go. Deploying and running a custom neural network on your phone or tablet is not straightforward, though, and the process depends on the operating system of the machine. In this post, I will focus on iOS devices and walk you through all the necessary steps to train a custom image classifier neural network model using the Wolfram Language, export it through ONNX (new in Version 12.2), convert it to Core ML (Apple’s machine learning framework for iOS apps) and finally deploy it to your iPhone or iPad.
Data Science at Home: Leverage Wolfram’s Device Integration to Analyze Your Vehicle’s Performance
December 31, 2020 — Andrew Steinacher, Lead Developer, Wolfram|Alpha Scientific Content
Cars are getting smarter and more connected, yet how much have you explored the technology that helps run our vehicles? I was curious to see how I could connect to my vehicle’s communication center and what kind of interface I could create in Wolfram Notebooks to report on the data gathered.
