Inverse Square Law - I have always wondered...

Perhaps you might say an area source consists of many point sources which is probably how the maths was developed Ted. There are probably edge effects as well.

This video might amuse you and George.

Couldn't run the video. Site said my machine doesn't have the needed resources, so I'll pass, sorry.

Getting more and more wary about downloading stuff to fix such problems. Only today, I tried to to download FireFox from a site other than Mozilla and Mr Norton intercepted it and killed it.

Quando gratis, caveat emptor . . .

i always get my Opera from their site. I have firefox but usually stick to the updates OpenSuse Linux provides from time to time.

If things are needed the Opera site usually gives a direct link to the original source.

The link is only for "amusement" really anyway and the content doesn't relate on here. It just shows some of the odd things about light. Some make me think stinking fish, can't be right.
