What is memory of water?

Mankind since the most ancient times by practical consideration found various wonderful properties of water. However until recently the science could not record and explain the observed phenomena. Water, it is also water - one atom of oxygen and two atoms of hydrogen, steadily connected. What can happen to them?

And only recently with the advent of the devices and technologies allowing to study substance on a nanolevel a lot of things begin to clear up. Remember that a water molecule - not just a ball. In it two atoms of hydrogen are attached to atom of oxygen at an angle of 105 degrees. From - for asymmetrical arrangements of electric charges it has also poles - one party is loaded positively, and another - is negative. Such structure in physics is called a dipole. The molecule of water is very steady. And from each other they from - for irregular shape and existence of electric charge can settle down differently.

All complex substances are ordered in the most favorable structures from the power point of view. They are recorded and known in solid bodies where communications between separate molecules are strong. In a liquid phase, with weak communications between separate molecules, any external influences can reconstruct them relatively each other. Then they can find, not the most energetically favorable but rather steady combinations. Such groups of molecules are called clusters.

The relative positioning of molecules of water stores information on the external influence which led to its education in clusters. Clusters of different structure, depending on depth of local power benefit of their education, can remain for a long time or quickly collapse. If the following impact is made energetically stronger than communications in a cluster, then the old cluster collapses and new is formed. Memory of water also consists in various relative recorded positioning of groups of molecules.

the Sizes of these clusters - about one milliard share of meter. And their structures can be studied by nanomethods now.

From the point of view of physics, in a data recording groups of dipolar molecules there is nothing new. Remember tape recorders and hard drives of computers. There the magnetic head according to information submitted on it ordered not electric, but magnetic dipoles on a thin magnetic film. And this record could be considered then by means of the same head. Nanotechnologies allowed to reduce sharply the sizes of heads, and they began to influence much smaller groups of magnetic dipoles that much more increased density of records and capacity of memory devices. For the opening which led to creation of such nanoheads, Albert Fer and Peter Gruenberg got in 2007 the Nobel Prize on physics.

And water, unlike flat magnetic films, has volume structure. Also can store (and stores) much more information. Now scientists by means of nanotechnologies take only the first steps in studying of memory of water. The whole new scientific direction opens. And Nobel Prizes here still ahead!]
