These pages will be useful for all people interested in fluid flows, including engineering and natural sciences students, hobbyists, water sports enthusiasts, and all who are just curious. The minimum reader background is the secondary school level, but this is planned to be an advanced course, also aimed at the students studying at a university. We will use mathematical notation only as a short-hand for physical effects we will discuss. The notation itself, however, will be the same as used in a university course. Therefore, if you are not a university student, you need not worry about the full mathematical meaning of the few symbols you might encounter, but if you are a university student our text will help you to understand those symbols better.
This is a work in progress. Keep coming to check for new pages to appear, or contact us to be put into the list of those who wish to be notified about new pages.
