AI and the Wolfram Language Work toward Partial Automation in the Search for Cancer

NOTE: The following post contains real medical images.

As more technology is folded into medical environments all over the world, Wolfram’s European branch has taken on work with the United Kingdom’s National Health Service (NHS) in an effort to partially automate the process of cancer diagnosis. The task is to use machine learning to avoid checking thousands of similar-looking images of people’s insides by hand for signs of cancer.

Computational Video Premieres in Wolfram Language 12.1

Version 12.1 of the Wolfram Language introduces the long-awaited Video object. The Video object is completely (and only) out-of-core; it can link to an extensive list of video containers with almost any codec. Most importantly, it is bundled with complete stacks for image and audio processing, machine learning and neural nets, statistics and visualization and many more capabilities. This already makes the Wolfram Language a powerful video computation platform, but there are still more features to explore.

Quantum Chemistry: Step-by-Step Chemistry Series

After working our way through chemical reactions, solutions and structure and bonding, we close out our step-by-step chemistry series with quantum chemistry. Quantum chemistry is the application of quantum mechanics to atoms and molecules in order to understand their properties.

Have you ever wondered why the periodic table is structured the way it is or why chemical bonds form in the first place? The answers to those questions and many more come from quantum chemistry. Wolfram|Alpha and its step-by-step chemistry offerings won’t make the wave-particle duality any less weird, but they will help you connect chemical properties to the underlying quantum mechanical behavior.

The step-by-step solutions provide stepwise guides that can be viewed one step at a time or all at once while working through a problem. Read on for example problems covering orbital diagrams, frequency and wavelength conversions, and mass-energy equivalence.

Structure and Bonding: Step-by-Step Chemistry Series

We’re back this week with more chemistry, to explore molecular structure and bonding with Wolfram|Alpha and its step-by-step chemistry offerings. Read more on chemical reactions and solutions from previous weeks, and join us next week for our final installment on quantum chemistry!

Structure and bonding in chemistry refer to where the atoms in a molecule are and what holds those atoms together. Molecules are held together by chemical bonds between the atoms comprising the molecule. Understanding the interplay between molecular structure and the electrons involved in bonding is what facilitates the design of new molecules, the control of chemical reactions and a better understanding of the molecules around us.

To master structure- and bonding-related calculations, the step-by-step solutions provide stepwise guides that can be viewed one step at a time or all at once. Read on for example problems covering Lewis structures, oxidation numbers and orbital hybridization.

From Sine to Heun: 5 New Functions for Mathematics and Physics in the Wolfram Language

Mathematica was initially built to be a universal solver of different mathematical tasks for everything from school-level algebraic equations to complicated problems in real scientific projects. During the past 30 years of development, over 250 mathematical functions have been implemented in the system, and in the recent release of Version 12.1 of the Wolfram Language, we’ve added many more, ranging from the elementary Sin function to the advanced Heun functions.
