Crystallography 101 is a work in progress, without any public funding behind it. After
visits, many users have contributed substantially to the
improvement of content by either finding mistakes or suggesting new chapters or programs.
Many interesting and stimulating discussions have come from students submitting answers to
the quizzes. Future editions of this tutorial hopefully will contain more quizzes and
answers on-line.
Any criticism as well as wishes for additions you may have are always welcome. I particularly enjoyed all the unsolicited positive response the users have provided. The kind responses are very helpful, in particular for my fund raising activities. If you have something nice to say, please let us know, in particular if you use crystallography 101 in a class or course. With your help, it will be easier to get funding to expand the tutorial and make it more professional and interactive. So far, I have written all the pages myself with few exceptions, and in spare time I power-pointed all of the sketches in the tutorial text. If someone wants to contribute, please let me know. I also write the CGI programs myself, and they are quite primitive due to my limited resources.
The next expansions will be a 2-d Patterson/Fourier map program, a full MIR solution from simple user data, and a chapter on molecular replacement. A R-free and cross-validation page is in preparation. The crystallization tips need urgent rewriting, but I haven't had the time yet, as usual.
Again, thanks to all who have contributed in one way or the other, and I wish you fun with 101.
Cheers, BR
