I'm gld you can find something useful. For the reason of keeping a work sheet as clean as possible, my preference goes to as short modules as possible and not too many extras. I can't view your work sheet because this site does not work as it should, not even for the minimal . Two days ago, James had 5 work sheets in optics, only 2 did download, tried several times. You have one work sheet mcd*.zip , it does not download as a zip but as a work sheet, as a work sheet it does not open in mathcad 11 "Failed to open document". First time since june 22 that a *.zip does not download as zip. That's not all: sometimes click right to download. sometimes click left to download ... normally click right. In > 10 years, it's the first time that Microsoft is confused by a web about downloading.
What to do ? Wait and see, read and go.
A full page of avatars, most are for joke, can't remove those you don't like, and you can have only one. Like Ford model T democratie ... you can have any color as long as it's black.... you can have any avatar you want as long as you have only one.
