No, in essence it is a logarithmic scale. They put it around a circle because it represents the significant part of a number when you write it in scientific notation. This is a number from 1 to 10, and when the value exceeds 10, it wraps back around to 1. (for instance 12 is 1.2 x 10)
Yeah, like a "standard" circular slide rule, but the scale is 10^(n/10), right? I'm still having a bit of trouble wrapping my head around it, but it's a real interesting idea!
I haven't had a chance to read that in detail yet, but just skimming the first part is interesting. I'll come back to that when I can spend some more time and brain cells on it. Thanks!
