Mathcad Tips

Mathcad Prime 10.0.1.0 is available for download.

It's a new, 2024 version of our "Happy Easter!" Easter Egg! What's different from the previous years' eggs is that this one is in Mathcad Prime 9, which allows us to use the "More Colors..." custom colour picker, for a far wider range of designs than before. The attached worksheet predominantly uses PTC's colour palette, which requires use of the custom colour picker... but there are some extra fun (non-PTC), previously unusable colours too, like pure green (0,255,0) and pink.   Happy Easter 2024!

Professor Tetsuro Tokoro (ttokoro on the PTC Community) is a member of the Institute of Electrical Engineers of Japan (IEEJ), and he has dedicated much of his time to teaching and studying electric circuit design for his college students at Japan’s National Institute of Technology (KOSEN), Gifu College.   A true man of math, ttokoro finds helping community members solve their problems to be very fun. He seeks out math-based brain teasers and shares them with the Mathcad community to gain the insights of his kind and very intelligent fellow Mathcad users. These include resistor meshes (including in 3D), perfect squared squares, and a puzzle where you must identify the minimum radius on a circle with n number of points where all distances between points must be an integer. Sometimes, he looks for problems on rosettacode.org to solve.   According to ttokoro, many of these problems are unique and won’t be found in a textbook (and many math textbooks in use were written before math software came to the scene) but demonstrate the value of math software. Ttokoro ventures to say that a lot of these problems cannot be solved by hand, or at least it would be unviable to do so, especially for students. Instead, Mathcad and its programming operators must be used to solve these problems.   Montage of resistor meshes and other fun problems ttokoro has introduced   Beginning in 2021, ttokoro has also become a prolific uploader of Japanese PTC Mathcad content on YouTube. Many of these videos share tips or are tie-ins to the puzzles he or others post on the PTC Community, including the Mathcad Community Challenges.   Ttokoro’s best resistor 3D mesh electric circuit. (Each edge is made by one ohm. Find the resistance between Node [0,0,0] and [1,1,2].)   Ttokoro first started using Mathcad with Mathcad 12, and his biggest requests for Mathcad Prime features are transparent colour availability and for the Animation tool to return. You’ll notice that in his brain teasers, as well as in his submissions to the Mathcad Community Challenges, ttokoro likes to show results with plots because it helps convey the meaning better than with math results alone and having more tools to show the results via images helps with that. This sort of thinking carries over to his academic work as well.   Ttokoro wearing his PTC Champion Jacket and PTC Mathcad T- shirt!   Thank you for your enthusiasm for math and contributions to the PTC Community, ttokoro!

PTC has a Mathcad Scripted Control design Working Group for implementing scripted controls in Mathcad Prime 10.

A Mathcad user for 25 years, Professor Valery (‘Val’) Ochkov takes to the mountains when not involved in developing training and educational software for fossil and nuclear power plants.  He’s shown below in the Chimbulak region of Kazakstahn.   Val has long been involved in the Mathcad community! See the photo of the “Mathcad Clock.”       This is from a post back in 2010!  Beyond answering questions, Valery is also known for using math equations to create designs and authoring Mathcad trivia challenges for other community members to participate in. Some of the more entertaining challenges might be the Hare and Snell’s law and the Problem of Cockroach Races.  The Bicycle Post where Valery quizzes the community on how to solve “How many strokes with a bicycle pump need to be done to inflate the tire to 5atm” also inspired engagement. When asked for hobbies that don’t involve hiking boots, Val assured us his hobbies really are writing books and articles about Mathcad.   He’s now deeply interested in using Mathcad for STEM education, the subject of his latest book, 2⁵ Problems for STEM Education 2 (2020). He says collaborations with community members were critical to developing the material.  Way to go Mathcad Community!  Keep Collaborating! Keep engaging and great things like a book is born!            

I'm sharing a recent long-form interview that PTC's CAD/engineering calculations general manager, Brian Thompson, had with engineering.com: https://www.engineering.com/story/video/for-power-mathematics-retire-the-spreadsheet Alongside with the video interview, there is also a written transcript. You don't have to share any of your own information to access it.   For Power Mathematics, Retire the Spreadsheet   Brian talked through a wide variety of topics, including why engineers and research scientists across many various industries choose PTC Mathcad and how those customers use it, the old and painful days of trying to perform complex calculations in spreadsheets, and some glimpses into the future of Mathcad.
