*Following my trend as of late to briefly capture the essence of charmingly old or neglected books as part of my duties as a digital archivist + librarian*
This is one of those classic AI books from my dad's collection that I read when I was younger, and only now appreciate in retrospect for its historical value. Below we can see how Turing machines (arguably our first model of the modern, but still primitive computer) and the programs used to do addition, multiplication, and exponentiation.
Note that 15 line(!) program to just multiply two numbers! We take that for granted nowadays since in Python I can just do all that with a simple " * "-sign, haha.
Or how a simple "counting machine" might be designed (like the odometer in your car):
This was published in 1974, but you can see that they were already thinking about all the implications of AI, such as how to use boolean logic to solve problems in medicine!
Or how this boolean logic can be implemented as an electrical circuit:
And here we can see those old engineers thinking about how to design a "heart beat" or a circuit that "pulses" (note from the title of the device where this research was being carried out):
