I wonder, then, what your basis is for saying so.
At least I give a source.

===========================

Sorry Richard. I never refer to sources. Except perhaps Ohm.
There's no way of guaranteeing reliability. I work things out for
myself so you'll just have to take my word for it.

I have a remarkably small book library. Although I did buy a
second-hand copy of Terman in 1947 which I still occasionally browse
through when I'm running short of ideas. He's most comprehensive.
Which accounts for his continued popularity. But he's not God. Anyone
who has actually tried to use him will know that.

I do have volumes from A to S of notes accumulated over the last 45
years. But some papers are about telescope making which was a hobby of
mine before our night skies became polluted with vapour trails and
other fumes. And some wicked kids stole my camera.
