A nice reference is Clifford Stoll's (author of A Cuckoo's Egg) article in Scientific American 2006: http://www.uvm.edu/pdodds/files/papers/others/2006/stoll2006a.pdf http://www.uvm.edu/pdodds/files/papers/others/2006/stoll2006... And a way to make your own sliderule: https://static.scientificamerican.com/sciam/assets/media/pdf/Slide_rule.pdf https://static.scientificamerican.com/sciam/assets/media/pdf...
