I suspect that re-arangement of molecular structures has influenced the refrationans of light waves?????   Is that clumsy supposition in the ball park Caleiasseia?


Your screen name is difficult, Please allow me to refer to you as Ms. C hereafter.  In any case, your posts are stimulating.

Caliasseia

There are two reactions generating I- ions, one fast and one slow, and similarly, two reactions consuming the I- ions and converting them to free iodine. As long as the system is far from equilibrium, the reactions will continue, acting as feedback loops for each other. Arrange for different transition metal ions to be present during the I- generation phase, and the resulting iodide salts are strongly coloured. There's also starch in there, which of course forms a complex with free iodine that's a deep blue colour.

I find inorganic chemistry much more intimidating than organic chemistry, but I understood your clear explanation.

Sorry about the Ms/Mr thing C..

He's got long hair so it's an understandable mistake :grin:

Here is a legitimate fun science video.  It is fun because Neil D, Tyson is animated as usual.   This guy is an extemporaneous speaker of remarkable ability.  This is a Q and A session.   Along about 14 minutes in, one of the questions is about religion.  He answers with class and respect for the questioner.   He also defeats the faith concept politely but decisively.

Worth the twenty minutes or so.  (well at least it is for me)      https://www.youtube.com/watch?v=bd993w3syBM

Going on two years since this thread was active.  It was begun by Sandra Craft aka Books and Cats.

I miss her because she is a class lady who was one of us. I do wish her well. If she ever sees this post, let it be known that she is fondly remembered by this old guy.

I will not leave out Silver sphinx ......Nor Claire.

Wherever you respected girls are.........Seasons greetings.

Given that most people struggle with legible handwriting already, the added complexity of cursive is an unnecessary burden. It is more practical and efficient to stick to standard print writing.

I failed to mention some of the other ladies that have rewarded us with their presence. Mags was an interesting person, fiery,clever, intelligent,very sensitive. There was the Christian lady in Pakistan who was held in esteem by we HAFers.  Where is Buddy, Dobermonster, or the Siberian Husky lady. What the hell?  We even had a Goth....I think she was Sweetdeath. I miss them all.

Right now we have only one participant from the fairest sex; Anne D. Thank you for your input Anne.

Dammit we need more participation from the other half of the world. There are something like eight billion humans on this earth and none of us would be here without the participation of those of the opposite sex.

People come and people go on HAF and other online forums. Most of them will be missed. Thankfully some of them occasionally return or can be found back on Facebook and co.
