General Philosphy:

In general texts can be expensive which is sometimes a barrier for students. In the world of open courseware and open source materials there is less and less reason to require a specific text for any class. For these reasons I am personally committed to finding free, or very low cost, texts for my classes.

For this class:

Because NDT is a new context for this class there is not a reasonable textbook. I will be finding and posting various resources for you to read and understand on this website.
