Yes. You can calculate logarithms by hand using pen and paper. Then, you can make divisions using the compass and a straight edge until you have a finely divided ruler and then mark logarithms on that ruler based on what you calculated.
After all, the slide rule was invented hundreds of years before the computer.
- kd5bjo 6y agoIf you want a base-10 scale, I think you only need to calculate the logarithms of 1/5 and 1/2 by hand, and the rest can be done by scaling those ratios (not to scale): | 10 | => divide by log10(1/2) : 1 | 5 | 5 | => divide by log10(1/5) : 1 |1| 4 |1| 4 | => divide by log10(1/2) : 1 |1| 2 | 2 |1| 2 | 2 | => divide by log10(1/2) : 1 |1|1|1|1|1|1|1|1|1|1|
