Forgot to add this. You can get the book online nonelectrical for less. It is nice to have a book where you can underline and look at things again you have found of interest.
I love electronic media due to its instant availability covering many subjects. If I am really serious about something it is nice to have a hard copy in hand.
I am old but deft with electronic media. I guess I am just old school.
“nonelectrical “
My stupid fingers did it again. It should have said, “electronically.”
