Gentlemen, (Hanno and Greg)
If I as a largley inumerate medic can be so bold, I think you have both done great work here. The current Doniol works well as do the hv tables and indeed the sin/cos tables.As we say in Cornwall, England, "Proper job".
I now need your superior mathematical brains to range over other areas of new and even greater importance. My latest enthusiasm. The Brown-Nassau spherical , graphical circular slide rule.
Please look at my postings and tell me what to do.
I think I now know I can make the thing from the graphs from the 2 papers, but it will be primitive without computer generated curves which are beyond my limited brain.
Gentlemen, please think deep and come to my rescue!
Best to both.
Francis
