In this presentation, you'll hear from University of Warsaw professors sharing their experience teaching an analysis course using Mathematica. The presenters give examples of problems where Mathematica can be used effectively as an aid in solving mathematical problems, or at least to inspire the idea of a solution.​ ​​ ​They have been teaching the course of analysis for computer science students for several years and augmented the standard course with computations in Mathematica. The problems chosen for the classes are those in which Mathematica could be genuinely useful in a way that did not involve simply applying some standard algorithm or plotting a graph, but which required the students to think and come up with some mathematical idea. Sometimes this idea is a guess inspired by a Mathematica calculation or a visual representation of the problem. Sometimes Mathematica can only verify this guess in special cases, and sometimes it can prove its correctness in full generality. In all such cases, we normally still want to obtain a rigorous mathematical proof. When using a computer program as an aid in mathematics, it is important to understand what such programs are well suited to and what they are not, and also what kind of problems (including incorrect answers) one can run into. In this presentation, we give examples of problems where Mathematica can be used ...

Over the last five years, SDGCounting has used the Wolfram technology stack to track and report on progress made around the UN's sustainable development goals (SDGs). As the capabilities of Wolfram have evolved, our methodologies and uses have evolved as well. In this presentation, we explore our work in 2020, which was focused on turning unstructured information into data. Specific topics include: automation of data gathering; turning narratives and reports into usable data; using Wolfram to make your ongoing topic research easier; tips and tricks for optimizing searches; and data import.​ ​​ ​The year 2020 is the fifth year of the SDG | Global Goals 15-year plan—2020 to 2030 had been designated as the Decade of Action to try to get on track toward achievement of defined targets by 2030. But the COVID pandemic is causing great disruption—estimates are that for many goals, there may be a 10-year+ setback. Country statistical offices are closed; data collection, already lagging by up to three years in many cases, is a mess. To get back on track will require augmentation of traditional United Nations counting methods with new methods relying on more contemporaneous—and less structured—sources of information. Over the past five years we have used Wolfram technology on most of our SDG projects, for example to integrate UN data with ...
