A man must have a hobby ....
The name for this non-commercial website comes from my daughter. As a teenager she would tell her friends: "Oh, he collects expensive bits of wood!"
When the latest PC is out-of-date in 6 months or less it may come as a surprise to many that an Englishman, the Rev. William Oughtred (1575-1660), invented a type of calculator around 1621 that would be in continual use for well-nigh the next 400 years - the humble Slide Rule.
My hobby is collecting slide rules. This website is a "display case" for my collection and for the slide rule related articles I have written. To learn more about the remarkable history of this 400-year calculating wonder I recommend the oughtred.org/history.shtml webpage or alternatively sliderules.nl/papers/ for my 2-page Dutch language summary.
For those wishing to nostalgically refresh their memories on how to use a slide rule or those of you intrigued enough to want to learn how such analogue calculators worked in the past, try out: sliderulemuseum.com/SR_Course.htm
For anyone looking for reference books on slide rules or on a particular slide rule maker, a comprehensive list can be found at:
