Please see this URL:  http://www.xs4all.nl/-johnw/PhysFAQ/General/hot_water.html
  This symbol"-" should be a "more or less" sign.  I do not have that sign on my keyboard.  Thanks for comments.  Joe L. Ogan

I suppose I'm going to have to try to reproduce the effect myself. I'll try it when it gets a bit colder here. It won't be long till we get well below 0°C overnight.

I'm wondering if the cold water is more likely to supercool?

Joe, I don't seem to be able to get that link to work. Try posting a few lines of the text and I'll try to google it.  Thanks!

If you have a "more or less"  sign please substitute it for the "-" in the URL. I got it by using the URL as shown and I was asked if it was the symbol of "more or less"  When I keyed that URL, the item came up.  It is quite lengthy because the guy who did it went into great detail.  If you will hit the URL that I submitted, it should bring up statement that the URL does not exist and will ask you if the proper URL is the one.  If that will not do it for you, I shall send you an email.  Thanks for comments.  Joe L. Ogan

Darn! I thought I tried a tilde, and I still couldn't get it to work. Thanks JP.

So, if I figure this one out, will you nominate me for a Nobel Prize?

So, maybe I am wrong.  Perhaps science is and should be based on what those think that can shout louder and longer than others.  Thanks for comments.  Joe L. Ogan
Imagine if we all mankind were, from a long time, in a spaceship with no gravity inside. Would you observe that effect, excluding obvious things as vaporization, hot container which melts the ice on which is placed, ecc? What if someone, one day, said: "on a planet's surface hot water can freeze faster than cold one". Would that make a big impression on mankind? Can you see the relativity of the effect? Do you understand that in physics a real effect shouldn't be relative?

There is a nice article on the controversy (and yes it is a controversy) here at the institute of physics Does hot water freeze first?.  I think some of the respondents are being too dogmatic - despite much effort a simple set of experimental conditions have not been defined that are consistent with theory.  In fact is is really difficult to even obtain self consistency.

Well, I thought that the majority of scientists agreed on this.  It is rather amazing to me that (I think) most scientists agree that the "Big Bang" Theory is the accepted way that the universe was formed.  To the best of my knowledge, that experiment has never been duplicated.  I am beginning to understand why primitive man devised the theory of religion.  It gave them an answer to every thing that they could not explain.  The Lord did it!  Is this the new scientific approach?  Thanks for comments.  Joe L.

I am under the school of thought that "hot water" cannot freeze as long as it stays "hot water". :P

How can you make such a statement?  Have you ever performed the experiment?  Have you ever seen a monkey type?  Is this a scientific statement?  Is this generally accepted by the scientific world?  Thanks for comments.  Joe L. Ogan

Yes, I've read it, but none seems to have answered my question about blondes and brunettes:

"brunettes get from their husbands more money than blondes!"

Amazing effect! I will name it: "lightarrow effect".

(Possible explanation: *those* brunettes have richer husbands because, not being as "flashy" as blondes in that county, they had to learn how to be smarter and so they succedeed to marry the richer men there [:)]).

I believe it's well accepted. It's simply a case of having enough monkeys, typewriters and time.
