The group of physicists of University of Oslo has found out that the skin of the person can similarly behave memristoru.

Memristorami it is accepted to name passive elements which establish a parity between integrals on time at most a current proceeding through them, and pressure on them. The first working sample of such element has been received three years ago by employees of company NR on the basis of a thin film dioksida the titan.

It is known that memristory most advantageously simulate properties sinapsov: consecutive connection of two correctly picked up elements allows to model transfer of nervous impulses to an organism. In the future memristory can become a basis of so-called neuromorphic systems which are projected with the account of architecture of nervous system.

Physicists from Sweden, the USA and Japan have described the first case of supervision of dynamic effect of Kazimira.

Let's remind: in the quantum theory weeding vacuum it is considered not as absolutely empty space and as area in which constantly are born and virtual particles disappear. Scientists have quickly enough understood that these fluctuations of vacuum can yield results giving in to measurement — for example, lembovsky shift, displacement of levels of energy of the connected statuses elektrona in an outside margin.

"The usual" effect of Kazimira which explain on an example of two mirrors (the spending not charged plates), placed in vacuum more often is connected with a birth and disappearance of virtual particles also. At rapprochement such plates as in 1948 has found out Hendrik Kazimir, should test an appreciable mutual attraction. It is possible to tell that the birth of virtual photons chokes in a narrow backlash between not charged surfaces, and in all other space — is limited by nothing. As photons put pressure upon mirrors, in experiences force of an attraction is registered.

Recent researches have turned representations of scientists aboutability of loose substances to maintain pressure

By scientists it has been established that the surface of a loose mix can sustain weight which stays in considerable dependence on coordination number of each particle of a part mix.

By scientists it has been established that the surface of a loose mix can sustain weight which stays in considerable dependence on coordination number of each particle of a part mix.

Thanks to presence of stable structures which are in each loose substance, they can sustain weight of other objects on the surface. These stable structures consist of separate parts which are called as "bridges". Results of last research of the German scientists have shown that the limit of weight which such "bridges" can keep a little depends on external forces, for example, from gravitation or interaction among themselves separate particles. Proceeding from the analysis of the received data, it turns out that influence on weight keeping, renders only average of neighbours of each particle. To prove the assumptions, scientists had to create three dimensional structure kolloidnyh solutions as their parametres have property to change in rather broad range in comparison with dry mixes.
