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.

Even the single atom – can be transformed into a mirror

Four Austrian physicists managed to develop the experimental scheme in which the single atom becomes one of resonator Fabri mirrors – the Feather.

Four Austrian physicists managed to develop the experimental scheme in which the single atom becomes one of resonator Fabri mirrors – the Feather.

The design of usual resonator Fabri – the Feather, consists of two mirrors, the main thing that these mirrors were parallel among themselves. It is necessary that in mezhduzerkalnom space passed a laser beam. At each reflexion of a beam, its some part will be uterivatsja because it will come to light. In the given experiment, the distance which overcomes light in a cavity, is not multiple to length of a wave of light. But if this parametre to change, in a pre-production model it is possible to observe the phenomenon of a constructive interference well and it is natural propuskanie, also will be maximum. But in case of change of size of an interval, the destructive interference which to appear in that case, will lead to falling of level of carrying capacity. Proceeding from it, it is possible to draw a conclusion that parametres of passage of radiation, are in direct dependence on distance between mirrors.

We break stereotypes: kernels of atoms in the form of a core

Calculations show, the rotating kernel of oxygen-16 can be deformed in 4 separate alpha particles placed along an axis of rotation. (Click a picture for increase)

Traditionally we represent kernels of atoms in the form of the balls comprising protons and neutrons. Earlier scientific already represented calculations according to which kernels can have the egg form; but last published work of scientists from Japan shows kernels of even more exotic form. In their opinion, quickly rotating kernels can turn to a chain consisting of separate clusters, including protons and neutrons. Similar exotic kernels can play an important role at formation in bowels of stars of such elements, as C₁₂ and O₁₆. The design procedure of similar structures developed by scientists allows to study even more exotic designs.

The kernel form makes serious impact on nuclear reactions, for example, in bowels of stars where all natural elements are created almost. If the atom kernel rotates quickly enough (usually as a result not the central collision or at collision and association of two small kernels), it can be deformed, turning from sphere habitual to our imagination in ellipsoid. This form inseparably linked with the strong interaction keeping together protons and neutrons (nucleons), and also centrifugal force counteracting it. For today scientists have already provided the experimental proof of possibility of existence of strongly deformed kernels with the relation of width to length about l or 1/3 for heavy elements. For easy kernels of such elements as carbon or oxygen, existed only signs of that the similar deformed statuses can be realised. But, despite intensive searches, experimental proofs of this fact did not exist.

Physics of a fireball

Fireball explosion is accompanied by generation of a powerful electromagnetic impulse. It is a source of intensive x-ray radiation. The basic contribution to radiation to a visible spectrum is given by not isothermal plasma of a cover. Presence of a water film at a fireball proves to be true supervision of several light shades at it, "exotic" black fireballs, and as features of its movement.

In the given work (1) the substantiation of plasma model of the nature of a fireball is resulted. At the heart of offered model the magnetic configuration – sferomak lies theoretically predicted bessilovaja. It arises in the channel of a linear lightning at repeated categories in development areas on it instability of type peretjazhek. Initial poloidalnym as a magnetic field the weak magnetic field of the Earth serves. In the course of compression tokovoj covers poloidalnoe the magnetic field increases and becomes comparable with an azimuthal magnetic field pincha. As a result of reshort circuit of power lines poloidalnogo a magnetic field in area peretjazhek are formed bessilovye magnetic configurations with the closed magnetic field which are a fireball basis. Depending on number merged bessilovyh cells energy and the sizes of a fireball can change largely. In external area, for seperetrisoj, power lines of a magnetic field nezamknuty also leave in infinity. The basic energy in it is reserved in the form of energy of a magnetic field.

On border with air the thin cover of not isothermal plasma is formed. In it on internal to separatise surfaces the diamagnetic current shielding it from a magnetic field plazmoida proceeds. On an external surface of a cover of not isothermal plasma there is the double electric layer which is a potential barrier for elektronov. As a result of intensive condensation of steams of water on negative and positive ions in air on border of a double layer the water film is formed. Water molecules play also an important role in formation klasterov in a double electric layer therefore the size and energy of a stream of ions essentially decreases. Besides, not isothermal plasma of a cover serves as the reflective screen for intensive cyclotron radiation elektronov from central bessilovoj to area. As a whole, the external cover of a lightning is the effective thermal and magnetic screen. Vsledstivii strong electrostatic pressure in a double electric layer the energy density in a fireball reaches an order of 10 Dzh/sm3.

The gravitational theory reproduces the superconductivity scheme

Already more than 10 years of mathematics of the whole world are engaged in studying of surprising similarity of the equations describing two, apparently, of absolutely various physical process: a curvature of space-time and interaction of the systems consisting of set of particles. Recently scientific used this mathematical similarity to reproduce work of the "standard" superconducting device. Though results at present do not show any new breaks, full conformity of the theory to experiment gives hope of the future active advancement in studying of other condensed environments.

Very often parametres of border of a certain area of space strongly influence that occurs in this area. Some scientists name this phenomenon «a holographic principle» by analogy to how two-dimensional hologrammes comprise the information on a three-dimensional reality. On the basis of this general principle in 1997 the American theorist from Institute for Advanced Study in Princeton has put forward the assumption of existence of mathematical similarity between two absolutely different theoretical designs. One of them is a theory of strings, in particular, describing features of a curvature of space-time in gravitational fields; the second – the quantum theory describing strongly co-operating particles in usual space-time (which in this case can be considered as border of bent space-time i.e. to assume for it smaller dimension). The hypothesis of the scientist consisted that on border always it is possible to transform the physical equation of the theory of strings in the bent space-time to the theory of a field having smaller dimension. For today it is not proved that it takes place in all cases, but, according to the author of a hypothesis, proofs exist.
