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!

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!

Hi Mathcad community members,   For those of you who don't know me (some do), my name is Andrew McGough and I'm the product manager for Mathcad here at PTC. I have talked to some of you in the past individually, but I don't get to participate as much as I'd like on the community. I hope this announcement is the start of me being able to be more active here.   I would like to share with you that PTC is announcing the end-of-sale for the following versions of PTC Mathcad, effective December 31, 2021:   Mathcad 15  Mathcad Prime 1.0 – Prime 6.0     Effective January 1, 2022, the only version of PTC Mathcad available for subscription will be PTC Mathcad Prime 7 and future versions of PTC Mathcad Prime. After December 31, 2021, PTC will no longer have the right to sell or distribute software versions moving to end of sale due to a third-party component contained in those versions.    I appreciate the passion of our Mathcad userbase, so I would like to pass along some additional information on a helpful offer. If you currently have a subscription license and wish to continue using your current version of PTC Mathcad while you evaluate Mathcad Prime 7, we are offering a multi-year renewal option that will give you the ability to use your current version for up to four additional years. If you decide to take advantage of this offer, it is important to place the order prior to December 7, 2021 to ensure no issues in booking the order or the subscription start date. PTC may decline or be unable to process orders received after that date. Please contact your PTC account representative or PTC partner for more information.    Please bear in mind that the use of old versions of software does introduce implicit risk in areas of security, hardware, and software platform support.    PTC will continue to provide technical support access, phone assistance and expert input for versions of Mathcad that have reached end-of-sale. PTC will not be able to issue new licenses or provide access to software downloads for end-of-sale versions.    Our customers in English-speaking countries received the End-of-Sale announcement on February 17, 2021. Our global customers are receiving the localized communication now.    We have put together multiple resources for you to answer your questions. Please refer to our FAQ for more information. We know this is a big change so the Mathcad team will be monitoring this thread for feedback.   Best regards,  Andrew McGough,  Product Manager, PTC

Hi All – I want to announce a critical bug fix release of PTC Mathcad Prime 4.0. We recently discovered an issue where some password protected areas can become corrupted on save/open. This is an issue we feel important enough to fix in a maintenance release. We’ve investigated the issue, submitted and tested a fix and will be releasing PTC Mathcad Prime 4.0 M010 later today. Anyone using Prime 4.0 F000 should upgrade to Prime 4.0 M010 – we’ll be removing Prime 4.0 F000 from download to make sure only the fixed version is available.   We do our best to avoid situations like this but sometimes bugs happen and when they do, we assess them to understand the impact on users. If they’re critical issues, such as this one, we do our best to fix them as soon as possible.   Many thanks,   Andy.
