CNC Machining
CNC stands for Computer Numerical Control, and is a method of controlling mechanisms and machines especially those used for manufacturing and fabrication.  At Harris Educational we use CNC routers in order to produce parts for our Reinventing Science kits.  Here you will find links and resources relating to CNC machining including original articles that we've published ourselves. {more coming soon!}

Open Source Software
Open Source Software is software developed by groups of cooperative individuals who share their design and code with others so that it can be commented on, improved, and expanded.  Open Source software projects offer choice, freedom of use, and much lower cost (often distributed and available for free and with lower total cost of ownership).  At Harris Educational we use Open Source Software wherever possible and practical and we support Open Source especially for schools and for students where budgets are tight and results are important.  Here you will find links and resources to open source software.

History of Technology / Retro Technology
Harris Educational's Reinventing Science kits are designed to make science and math concepts more accessible and more fun by relating them to invention and history. We feel that there is a great deal to be learned about science and technology by looking at the ways people thought and used concepts in the past.  To that end we've assembled this list of great resources (many of them video clips posted on YouTube) about the history of technology and sometimes the use of older ideas today (retro technology). Many of these links have featured as a story of the day on our Fan Page wall on Facebook. Like us and become a fan on Facebook if you want to see the latest Retro Technology links and resources the easy way.
