You have reached the personal website of Piet Lammertse .
This site gives musings on things that have caught my attention over the years. The idea is often to have "simple" basic principles clarify subjects too often considered "difficult".
The selection of subjects is purely personal, and largely a matter of taste.
This site is much like a personal blog. For easier reference, it is organized by subject instead of chronologically.
The depth varies. Some parts are mere sketches of ideas, others are more elaborate, but all of them are works in progress.
The site contains a serious text on propeller theory, and there will be a similar text on haptics as well.
Please feel free to use any of this material, but do so at your own risk :
some of it is tested in practice, but none of it is peer reviewed.
