Some questions about light

I miss proper spelling of my user name even more, Ferd.

Please accept my sincere apology for the spelling error. I intended no slight.

There seem to be times when my dyslexia (mild) breaks the path between my brain and my fingers. Letters such as "n" are sometimes turned backwards by part of my brain and apparently another part recognizes the error and occasionally rather than correcting it, just eliminates the letter altogether. I don't get called out on spelling very often. I suspect most errors are either not noticed or taken to be typos. Of course when an error is in someone's name then it is recognized. One interesting part, to me, is that I do much better reading at speed, recognizing whole words, and not trying to see the individual letters. I know one woman who is just the opposite, she has to see the spelling of every word and will comprehend almost nothing if she doesn't read slowly.
