Re: Jet
M. Čaplins vai nu tīšām, vai kā citādi ignorē vienu, man domāt, ļoti būtisku faktu - šādu struktūru pastāvēšanas ilgumu.
"Our results highlight the efficiency of energy redistribution within the hydrogen-bonded network, and that liquid water essentially loses the memory of persistent correlations in its structure within 50 fs" (doi:10.1038/nature03383)
"With increasing coupling strength, the anisotropy decay speeds up and the long-lived components vanish. This effect can clearly be assigned to intermolecular ET which is expected to be at least partially coherent. The anisotropy decay can now be fitted with a single exponential decay, resulting in decay times of 75 fs" (doi:10.1063/1.2919050)
"What has been demonstrated is that water molecules form transient bonds with other water molecules, creating a larger ultrastructure—but these water structures are extremely short-lived. They are not permanent. In fact, research shows that water molecules very efficiently distribute energy from these bonds, breaking them apart in approximately fifty femtoseconds. Scientists can argue about whether or not water can display ultrastructure lingering for longer than femtoseconds under certain conditions—but they are arguing over incredibly small fractions of a second."

So, ūdenī zināmos apstākļos uz dažām sekundes kvadriljonajām daļām var izveidoties molekulāra superstruktūra? Tas ir... piemīlīgi.
