    New steps towards the creation of a perpetual-motion engine
    The new science on friction: machines of the future will resemble fantastic creatures

    Friction can be useful. This property is being studied as a new breakthrough area of research in the science of friction, tribology, through the lens of synergetics (self-organization)

    Everyone in mechanical engineering knows the problems of friction. But only a very few people understand how friction can be useful. If you are not one of them, then do not worry. Only scientists themselves have made this discovery very recently.

    All researchers have unanimously hailed the new research direction in tribology as a breakthrough and a strategic move. This path of study examines the formative effect of friction on the basis of synergetics (or self-organization).

    Two discoveries of international significance form the scientific basis of this line of research: "the effect of wear resistance when friction is present" (1964) and "corrosion of metals in aqueous solutions" (1992). Dmitry Garkunov, an outstanding Russian scholar, Professor and Academician at the Russian Academy of Engineering, is the man responsible for these discoveries and the founder of this scientific movement.

    The essence of tribology based on self-organization lies in the special interaction of a part possessing regular surface pitting and a metal-coating additive. Regular surface pitting consists of special irregularities that are artificially created on the surfaces of rubbing parts, a system of micropeaks and microdepressions of the correct form. The metal-coating additive represents a special supplement to the lubricant containing quasi-liquid copper nanoparticles.

    The copper nanoparticles fill the pits in the surface of the steel or cast-iron parts, counteracting the wear caused by friction between cast iron and steel, steel and steel or copper and copper, which reduces the coefficient of friction in joints from 0.1-0.05 to 0.03-0.003. In addition, a special protective, continuous and constantly renewing property arises as a result of the interaction of this lubricant and such special pitted surfaces of rubbing parts: the so-called servovite copper film, which has phenomenal physical properties.

    The film is formed by the thermal and electrical energy that is generated by friction as well as by the chemical reactions of elements. As a result, the process of friction is transformed from being a destructive process into being a creative one that is similar to the movement of joints in the skeletons of living organisms, which also contain rubbing surfaces and the analogy to metal-coating lubricants: cartilage and synovial fluid.

    Scientists from around the world are devoting increasing attention to this line of scientific research about friction. Currently a School of Tribology based on self-organization is being formed at the Bauman Moscow State Technical University in Russia.

    Special laboratories are being equipped here with triboengineering devices that allow for pursuing scientific research. New types of metal-coating lubricants are being developed here and new methods for testing them are also being created. A small business to license the lubricants is planned to be created.

    Scientists discussed data from the latest tests of motor oils containing metal-coating additives in Norway and Germany at a national scientific research seminar and workshop dedicated to the "Results of the Implementation of Wear-Resistant Technologies in Metalworking Processes and Operations," which was recently held in Orekhovo-Zuyevo at JSC 'PCP 'Respirator', which is a subsidiary of the  Aviation Technologies Holding. The effect of their use is obvious: fuel consumption is reduced by up to 23% through reducing friction-related losses.

    New tribotechnologies are becoming more widely used in the transport, aviation, marine, chemical, metalworking, heavy machinery and agricultural machinery sectors. Already today they allow for:

    –reducing the consumption of lubricants by 2-3 times;
    – reducing the number of accidents by improving the reliability of friction joints;
    – reducing the atmospheric emissions of vehicles by 2-3 times.

    In the future scientists propose creating closed durable universal friction joints on the basis of new nanoscale tribomaterials and tribotechnologies. In terms of their physico-chemical mechanisms, these joints will be practically identical to the joints of living organisms with all of their natural self-organization. In other words, engineering will employ natural mechanisms to an increasing degree, and machines will more closely come to resemble animals.

    Academy 'reform' is stifling Russian science

    Insufficient funding, more bureaucracy and an inefficient government funding system are sapping the life from Russian research, says Alexey Yablokov.

    It is now a year since Vladimir Putin's government announced sweeping reforms of the Russian Academy of Sciences, stripping away its independence and placing it under the control of a new civil agency.

    How are things going? Not well. Unfortunately, some of the gloomy predictions of critics at home and abroad that the changes would stifle research and weaken Russian science seem to be coming true.

    I can speak as a member of the academy who works at one of its institutes. Formally, all of these academy institutes now belong to FASO, the government agency set up to manage us. The agency handles organization and finances, but the presidium of the academy continues to manage the scientific research. That's a very silly combination.

    As part of its new role, FASO demands information from institute scientists that would be funny if it were not so tragic. We are asked to strictly plan our research. For example, how many papers will we write in a year — in two years? What kind of discoveries will we make in two years? On the basis of our promises, they then give us money.

    There has, of course, been a great increase in paperwork. FASO says that it needs all this bureaucracy to guarantee our funding. The government transfers science funds to FASO, which then divides them among the institutes for salaries, expeditions, equipment, research, and so on. And just like any other bureaucratic organization, FASO wants to know what it gets for the money it gives.

    Not that there is much money. There are so-called mega-grants for scientific projects, but the academy receives only 30% of the budget that the government allocates to science. The remainder goes to the high-technology business area at Skolkovo near Moscow, the Kurchatov Institute (a national research centre) and other places.

    “We are creative people — and we need conditions in which our creativity can thrive.”

    It was clear that Russian science needed reform. But the situation now is ridiculous. What the government should have done was to strengthen the way science is funded, following Western examples, such as in the United States, the United Kingdom and Germany. There, when the state wants to support science, it mostly gives the money to an independent science agency, and the agency then divides it among the researchers, taking advice from the wider scientific community. The agency staff understand how science works — they understand which teams need support, and which teams say a lot but don't do much.

    In my opinion, the government wanted to liquidate the academy as a distributor of independent opinions. And of course, it wanted to get its hands on the academy's huge property portfolio.

    Traditionally, academy institutes, scientific stations and labs own a lot of buildings, many in very prestigious areas, such as the centres of Moscow and St Petersburg. The government probably wants to use these properties to make a profit. They have already taken some of the buildings from the presidium of the academy, mainly on Leninsky Prospect in Moscow, where they took two floors.

    We have been told that we, the academy, have one year to get used to the new system. But FASO will really be in charge in six months. It has already announced that it will cut 6,000 administrative jobs at the academy by 2018.

    Before, when I had to go abroad for scientific events, my assistant would take my passport to a specific department that took care of my visa and tickets. There were at least 50 people in that department in Moscow, and I never had any problems. Just recently, I had to go to France — but when I called that department, I was told that there were only five people left. I made the arrangements myself, which wasted time that I could have spent doing research.

    That might not sound like hardship, and it is true that some scientists are spending too much time at their holiday dachas and not in the lab — but this is because we have no money for good equipment and not enough money for field trips and expeditions.

    Of course, when the Soviet Union collapsed, many scientists simply stopped working and went to their dachas to grow potatoes and carrots, to have something to eat in the winter. The situation now is not so horrible, but I know that many scientists have another job elsewhere, just to earn some money on the side because their salaries are not enough.

    This is all heading towards the collapse of Russian science. Right after the reform was first announced, a huge number of young scientists and mid-career researchers with prospects and connections immediately turned to the West or the East. There are more and more of them, and they are now spending more time abroad. About three years ago, more people opted to stay at home when the salaries increased a bit. The brain drain slowed down, but about six months ago, it speeded up again.

    It is not too late to recover the situation. First, the government has to give us more money. Second, this money has to be distributed under the oversight of the scientific community.

    I am a biologist, and biologists know that some animals are not able to reproduce in captivity. Scientists are like that, too. We are creative people — and we need conditions in which our creativity can thrive.

    Chances are, this is bs. What he is suggesting they do is exactly what he mentioned they did at the start - give the money to an organization and they distribute it.

    Maybe he got denied funding.

    As well, if people want to move abroad, let them. Brain drain doesnt exist if everyone is educated.

    But, I bet after some time, these specialists and new ones will find other methods. Previous system was real bad.

    The problem is, all these specialists (in all countries) will talk about how important their field of expertise are, and how they need lots of funding. It seems Russia is funding now organizations based upon the importance the research will be. Hence fund them. So there could be a lot of BS research like there is here. If they are hurting for cash, maybe they should look at getting research grants from private enterprises and other agencies.

    Moscow State University president calls for returning astronomy to school curricula

    PLATEAU SHATZHATMAS, North Caucasus, December 13. /TASS/. Russian higher education community insists on returning astronomy as an academic discipline to general school curricula, Dr. Viktor Sadovnichy, the president of Moscow Lomonosov State University said on Saturday.

    He took part in a gala ceremony of opening the Caucasus Mountainous Observatory in Russia’s North Caucasian region of Karachai-Cherkessia.

    “I think astronomy must be returned to the curricula of general schools,” he said.

    Reforms depend on the people who carry them out and “lopsided decisions occur at times,” Dr. Sadovnichy said.

    He indicated that fundamental sciences, which are the locomotives of human development, suffered considerable losses in Russia in previous years. One of the landmarks of Russian science, the legendary Moscow Planetarium that had become an integral element of the history of Moscow City, was practically eliminated.

    Moscow State University helped with it re-establishment and reconstruction. “Now the lines of people waiting for admittance are as huge as the ones described by /Soviet poet of the 1920’s and 1930’s/ Vladimir Mayakovsky,” Dr. Sadovnichy said. “We’ve begun to fight for astronomy.”

    “Everything is getting restored step by step,” he said. “Theme compositions have already made a comeback and considerable efforts are being made in mathematics.”

    “We’ve rebuffed an assault on the system of inter-school competitions in academic subjects and it embraces almost two million school kids at present,” Dr. Sadovnichy said.

    He also recalled recent proposals to revive school-leaving exams in history and to make enter them on the list of mandatory Unified State Examinations.

    “As the next step, we’ll insist on the return of astronomy as a subdivision of some other discipline or a separate school subject,” he said.

    In Siberia, university-led consortium develops advanced OLED matrix
    Researchers at Siberia’s Tomsk State University of Control Systems and Radio Electronics (TUSUR) have created Russia’s first prototype of a full-color organic OLED matrix developed by using printing technology, and have also come up with an instrumentation system to analyze the characteristics of such matrices, TUSUR announced.

    TUSUR has teamed up with scientific and industrial partners in Siberia and other Russian regions to develop a brand new technology of printing organic displays. The project is aimed at using printing methods to create domestic organic LED semiconductor based matrices.

    “OLED displays are superior in many ways to plasma and LC ones, but this country still doesn’t have its own technology to produce these… A technology will be developed to help set up shop completely independent from foreign suppliers,” said Alexander Shelupanov, TUSUR’s vice rector for research activity.

    One of TUSUR’s partners in the endeavor, St. Petersburg’s Institute of High-Molecular Compounds, is responsible for the synthesis of raw material, or ‘powders.’ In Tomsk, another partner, Tomsk State University, is tasked with making a special ‘powder’-based printing solution, and also with determining the composition and parameters of solvents. TUSUR is in charge of the entire effort, enabling the printing process and assessing its overall results.

    Sweet, future Russian 100% made OLED TV's. If they can produce enough of them and make them cheap, they could lead the OLED market since there is really nothing out there in decent price.

    Very promising development of more efficient superconductivity. Russian scientist have created a super super conductive materials that can hold people literary in the air. Shocked   Superconductivity is not new.. but the level they have taken this science is super amazing..  The video is in spanish , could not find any in other language.. but the images speak for itself. about the possibilities for new forms of personal transport. other than train.. but also new sports ,and also could be used to replace electrical power lines in cities and for laboratories to maintain two elements separated.. they say the possibilities of this new superconductivity technique is the the next BIG thing .

    Moreover in the comments on his blog he's explaining about how he has little chances of breaking through into real investment and production, as the 'big man is keepin' him down'. That's to say how he has no hope of funding while so much has been invested into conventional rocket technology and the rocket engine makers are such big players in the Russian space industry.

    Which is a sure sign he's full of shit. If he actually published and explained his patents and findings, he'd easily win the Nobel Prize in Physics; probably a couple in a row - and would get worldwide recognition, fame, fortune and as much investment as he desires both from Russia and abroad.

    But of course he's not going to do that; he's just going to publish a few videos of a tin can on wheels propelling itself a couple metres. And then wait 6 years for everyone to have forgotten about him, and then come back and give an interview to some website.

    Being able to manipulate gravity would be an enormous breakthrough... whether it is a wave or a field... gravity and acceleration are related.

    Being able to separate an object from the gravity field or gravity waves around it means the propulsion needed to take off from earth and leave earths orbit would amount to that needed to overcome air friction... in other words if you were not in a hurry the power of a ceiling fan would get you into orbit.... and beyond.

    You could cancel the gravity of Earth and use the moons gravity to take you to the moon...

    Yep which is exactly why it's about as likely as my ass for the next 300 years.

    Of course gravity imparts energy/potential energy to any mass and there's no way around that. So either way you'll need a power source that would give enough power to enable an object to achieve escape velocity; whether its an engine within the object itself that effectively propels it without having to eject mass (i.e. circumventing Newton's 3rd law by just using that same amount of energy to counteract gravity instead), or having some sort of anti-gravity generator on the ground which emits some sort of narrow zone where all the matter within will have the Earth's gravity cancelled out for them (would take up a hell of a lot of power).
    The former case seems to be what this hoo-haa here is about, but I'm highly skeptical to say the least.

    On a side-note I remember when I was a kid I had a PS1, and the game Wipeout on it. Basically the story in Wipeout as far as I can recall - is that anti-gravity engines, at least in some form, were developed by the year 2018; and though they were invented somewhere in Europe or North America - there were some problems and at least one of the inventors went to Russia to pitch his technology there; which investors or the Russian government eagerly agreed to fund.
    As a result by 2050 or so, there were at least 4 anti-gravity tech companies in the world; who built anti-gravity racing craft and sponsored championships in order to demonstrate their technology, including for potential military clients - and the biggest company with the fastest AG craft in the game is actually the Russian one.

    Aside from the issue of cranks, the established theory pertaining to gravity (GR) is rife with problems and
    has a dogmatic cult-like enforcement in the scientific community. Papers are dismissed as being too speculative
    when the whole subject is one big speculation.

    The so-called tests (e.g. precession of the perihelion of the planet Mercury around the Sun) "proving" GR are a joke.
    There are an infinite number of theories that can fit these tests. In GR the claim is made that matter-energy tells
    spacetime how to distort and spacetime tells the matter-energy how to move. But there is no actual instrument
    of this communication. There is no field just magical distorting geometry. This is why talking about gravitons and
    GR as being self-consistent is stupid. The notion of gravitons comes from field theory attempts to substitute GR.
    GR has no field to quantize and hence on gravitons. This lack of a quantizable field has been the source of the stall
    in the development of a theory of gravity consistent with quantum mechanics and all the other forces. We have
    attempts to work around this "magic spacetime geometry distortion" of GR with loop-quantum gravity and string theory.

    There is a stream of alternative theoretical thought (e.g. http://arxiv.org/abs/gr-qc/0204062v1) which is basically
    a fundamental challenge to the notions on which GR rests. Frankly, the period in time in which GR appeared was
    just too early (it predates quantum mechanics) and subsequent core revisions are much more realistic (BTW, they
    satisfy all of the GR tests). Anti-gravity actually has physical sense in field theory. There is no anti-gravity in GR.

    So what is 'anti-gravity' exactly if it has been observed not even once; not in nature, not experimentally?

    Though you hit upon a good point when you bring up gravity as something where it's not so easy to define a 'field' as such.

    We talk about an electro-magnetic field.. basically it's a region of space time where charged particles will behave differently; they are affected, their trajectories change as they're acted upon by a force; each other.
    Neutrally-charged particles on the other hand aren't affected at all.

    We also hear talk of a 'gravitational field', most often in science fiction although I presume it's an actual scientific term too. On the face of it, it has similaries to electro-magnetism; in that it's a region of space time where particles with mass will behave differently; a force will act upon them; manifested by each of them on everything else.
    Like their neutrally-charged particles in electro-magnetic fields; particles/waves without mass (e.g. light) don't exert or feel any gravitational force at all - YET, they are still affected and their trajectories do change, as space-time itself is curved by gravity; the geometry warps as you said and light has no choice but to travel through that geometry.

    Perhaps the answer is is that we really are missing a few pieces of the puzzle in regards to gravity.
    After all, electro-magnetism can affect particles without charge too.. indirectly, if they form a molecular structure through which charged particles flow freely - then a force can be exerted by the magnetic field on the whole object. Indeed all molecular structures and structures of matter in general are formed by electro-magnetism (and in part, the strong & weak forces). So defining electro-magnetism as a 'field' as such - is not actually so simple either.

    Maybe something like that is going on with gravity too. Gravitons could actually be evenly spaced out everywhere in an empty vacuum; and cancel out each other's effects due to their equidistance from each other; allowing anything without mass to go through completely empty space with no deformation of trajectory at all or going through any warped space-time.
    However, mass causes local concentrations and dispersals of gravitons, and that leads to the actual perceived warping of space-time.
    There are many possibilities and it's too early to judge.

    As for whether it's a field or not.. well first one has to define what a field is exactly. We talk about an electro-magnetic field; as in a region of space time where some force acts upon particles with charge (but not on neutral ones).. in the same manor we also talk about a gravitational field; a region of space time where some force acts upon particles with mass (but not on ones without).

    If you want anti-gravity, we already have a force which

    Not sure where i am suppose to post this but a true tragedy has happened in Russia. cry

    Blaze devastates Russian academic library

    One of Russia's largest academic libraries, which contains millions of unique historical documents, has gone up in flames in Moscow. A part of the building’s roof collapsed before dozens of fire fighters managed to contain the blaze.

    This is catastrophic.

    I am wondering who was responsible, and why they did it.

    I am assuming there are copies, including digital.
