M. Casco Associates publishes run-time books for physics or math students in high school or college. Subjects are mechanics, dynamical systems and chaos. We offer these books at no cost to anyone interested. Until we get around to converting to the html help system, if you are running Microsoft Vista you will need to download a free program from Microsoft to read the help files in the run-time books. Follow this link to the Microsoft help reader .

Run-time books use mathematical simulations of the subject system instead of static illustrations, allowing experimentation with the concepts covered in the text. Our run-time books have a password protected "teacher" level of access which allows teachers to modify the text or create their own lessons, and create new mathematical models to illustrate the points they are making. For more about any of our titles, click on the appropriate cover image at the right.

For folks who don't want to download and install the run-time books, we offer online versions of two of our titles, "Order" and "Physics 1". These are powered by Java rather than the C++ programs that power the run-time books. That imposes some serious limitations on the capability of the online offerings. You may click on those links at the left.

IMPORTANT CHANGE
The incessant spamming we got by having our email address published in the "Are there any questions?" mailto links on the pages in this website forced us to place an impediment to the automated email address gathering programs out there. If you click on a question mail link your mail handler should open up with a To: address in the form xxxxxAxxxx.com. You will need to replace the A with the @ symbol before you can send the question. If you try to send the question with the A in the address it is likely that your mail handler will complain to remind you that the address is illegal. Click on the "Our support folks" link at the bottom of this page for an example.

Those of us who write online material including Java applets, and those of you who need to run those applets are caught in the crossfire of the Java war. Microsoft tried to take over the Java virtual machine business a few years ago and failed. Sun Microsystems, the original Java company, won that battle and Microsoft is giving up, abandoning their Java technology and their support for Java. All new computers will now be shipped with the Sun Java runtime environment(JRE). That means that when websites are updated, the authors must make a choice about whether or not to move up to the modern Java language, not constrained by the limitations of the Microsoft virtual machine. At M. Casco we have decided to move on, since the move will be have to be made sooner or later. Consequently if you have a computer shipped before 2004, you will probably need to download a free Java plugin from Sun and install it on your computer in order to use the applets included on this website. We apologize for any inconvenience. It seems that this is one of the prices we have to pay as customers for progress in the technology marketplace.
