    In Russia, the slide rule called a logarithmic rule. But we can not calculate with this device ... logarithm or 10^x. Or I'm wrong?

    One solution of one student

    It is for Mathcad Mad House - Маткадовский дурдом

    No sure if the slide rule split his head in two or he is making it part of his brain.

      I was able to solve differential equations on such device (Robotron?) in my student years. If you divide by zero, the carriage of this device goes from left to right - to the stop and there chirped until it laboratory assistant stopped.

            There is a story about the slide rule of Igor Sikorsky's cousin and its burn marks.

             

            See: https://sikorskyarchives.com/wp-content/uploads/archives-newsletters/NEWS-2022-10.pdf

            “I recall being in Prof Sikorsky’s office asking for
            help in calculating rotor performance. Professor
            Sikorsky, as he was called, was Igor Sikorsky’s
            cousin who had become the company’s chief
            aerodynamicist. When I sat down next to his
            desk, I noticed that his extra-long K&E slide rule
            was full of burn marks because he often rested
            his cigarette on the slide rule while doing something
            else. I asked Prof what he would do if the
            cursor ended up directly over a burn mark obscuring
            the answer to his string of calculations.
            Without hesitating, Prof replied, ‘I make-ed verry
            good guess.’
