ln() vs. log()

[Csaba Tizedes]

Lots of E and I&C engineers here...
I'm a mechanical, so I believe that the HP32SII keyboard is the only one which is designed for the engineering calculations:

LN() and EXP() as primary(!) function,
Y^X and 1/X also as primary(!) functions.

With this keyboard layout any engineering problem solved as fast as possible.

In the nature everything is depends on how many driving force is available. No more changes will be done what is available: everything is exponential because its derivative is also exponential function: No more U235 will be splitting what is available, no more people will be die what is lives now, not cooles below your room temperature what is the temperature outside - because almost all the changes in the nature exponential. Solution of a simple differential equation.

I know it not everything is simple. But lot of things is that.
