Water is one of the most important substances on the planet yet mystery still surrounds many of its properties, exactly how much do we really know about it ?

What makes water so fundamentally important to life ? Why do ice cubes float ? Why does it freeze from the top rather than from the bottom ? This article delves in to these mysteries and more.

"We are confronted by many mysteries, from the nature of dark matter and the origin of the universe to the quest for a theory of everything."

Since when did your belief become fact? and guess what.......... I told ya so Cheap post. Why not go take a bath or something? Please.

No sorry but that is what they are saying. The study makes a clear distinction between the two structures. One as having a more disctinct 'pyramid' strucure and one that does not. From your source; The shape of a water molecule is such that each H2O molecule is surrounded by four neighbours arranged in the shape of a triangular pyramid - better known as a tetrahedron. They are talking about the structure of hydrogen bonding here not a pyramid or tetrahedron. They (triangular pyramid and tetrahedron) are one in the same. That is all old news the author of the article was telling you, so you'd c... [More]

Cheap post. Why not go take a bath or something? Please. Now you want me to take a bath in all those pyramids, you sick puppy LOL I'm scared of water now LOL Just a side note here. Copasetic knows what he's talking about, I have learned many things from him. It's wise to listen sometimes and ask questions. He is more than willing to answer them for you as he has shown.

The self-gratifying posts of trying to act like you have something to teach when you do not is annoying. As I have already said, I understand the article I posted but it you who do not understand my comments on the article that went beyond it at all obviously. Oh well.

Yet of course there is more to learn of course. As I have said I think that lower-level structures like the actual chemical compositions of H1O, H2O, and H3O will also tie in if someone searches. You will find a harmony between these two super-structures and these three chemical bonds. The self-gratifying posts of trying to act like you have something to teach when you do not is annoying. As I have already said, I understand the article I posted but it you who do not understand my comments on the article that went beyond it at all obviously. Oh well. That's interesting coming from one who does... [More]

A pyramid is made of triangles, No? And the triangle is the simplist of shapes. Chemically you can not get simpler then a triangle, other then a straight line. There is nothing mystical about pyramids.

That's interesting coming from one who doesn't seem to have worked out Gen Chem: Acids and Bases Obviously, since you seem to understand it all so well (And I obviously have no idea what I'm talking about and "nothing to teach" in my self-gratifying way) I'm sure you wouldn't mind solving some simple problems like "In a 1 liter, .03 M solution of hydrochloric acid, how much H3O+ exists". Or since, you obviously understand and I don't maybe you could answer a question like; "In a .5 M sulfuric acid solution at equilibrium (pH 4.1) how much of each each exists; H2SO4, HSO4-, SO42-, H3O+ and OH-....

Due to my own profession, I've gone through basic chemistry as we understand it. And I laughed my ass off the entire time........... Not because what I was learning was wrong....but because what I was being taught was the be-all/end-all. How can we be this arrogant? It's as if we've learned nothing from our own history. Scientists are ostracized if they so much as even attempt to suggest something remotely less than mainstream. Have today's scientists forgotten what people like Copernicus and Galileo went through? Instead of the stockade or even worse forms of torture, scientists today can hav... [More]

I heard Lars Petterssen talk about this research at an X-ray conference. Actually I heard a lot of people talk about the structure of water. Everyone and their mother seemed to be jumping on the band wagon. From basic chemistry and group theory we expect liquid water to have a loosely tetrahedral structure. Of course since it is a liquid this structure should be transient and fluctuating. The majority of this research is on the amount of `disorder' in water. The data `showing' that water has small regions of ice-like order (which was the whole point of Petterssen's research) is rather unconvin... [More]
