[zerogate]

Dmitri Mendeleyev, at the age of twenty-six, attended the First International Chemical Congress at Karlsruhe in 1860 and was impressed by discussion there of methods for calculating atomic weight. He became concerned with the problem of order amongst the elements and made a set of sixty-three cards listing the various chemical and physical properties of each, spending most of his spare time in attempts to arrange these in ways that made scientific sense. By March 1st, 1869, he had tried and rejected hundreds of possible patterns and that afternoon, following the failure of his latest system, he fell into an exhausted sleep – and woke up with the answer.

In order to make sense of the elements, Mendeleyev realised, all he had to do was arrange them, according to their atomic weights, in eight vertical columns. As soon as he did this, they fell into natural patterns, with elements of similar properties such as acidity, hardness and melting point, all grouped together. By evening of that momentous day, he had drawn up his celebrated Periodic Table in which the relationships between various elements were made clear by their regular spacing.

Mendeleyev refined and improved the table later, and in the ensuing century it has been extended and subdivided in a number of ways to allow for new discoveries. But despite the suggestion of over 700 other versions in the interim, his pattern remains the best and most useful yet devised. The strongest test of its validity has been the way in which gaps in the table, deliberately left there by Mendeleyev, have been filled by the discovery of new elements (we now have 107), whose existence the table clearly required. Mendeleyev himself pointed out three major holes, and accurately predicted the properties of gallium, scandium and germanium, which were not actually discovered until 1875, 1879 and 1885 respectively.

Mendeleyev’s brainstorm clearly depicts an underlying pattern of nature, an order amply confirmed and explained by our new knowledge of the behaviour of electrons and protons. And it seems proper and satisfying that this insight, the basic shape of the “dream table”, should have come to him in his sleep. It is not, of course, the only great inspiration to have been arrived at in this way.

[...]

In 1865, another mental breakthrough was made by the German chemist Kekulé von Stradonitz while travelling half-asleep on a bus. He was convinced that the atoms of chemicals, particularly the complex organic molecules, were arranged in special structural forms with their own particular properties. Starting in 1858, he successfully worked out the shape of a series of carbon compounds, but one in particular continued to elude him. He was unable to make sense of benzene, a substance discovered by Michael Faraday in 1825 and in increasing use as a base for new synthetic dyes. Kekulé worried over the problem, but could find no solution until that day on the bus, when it seemed to him that he saw atoms whirling in a serpentine dance. As he watched the movement in his mind’s eye, the tail of one long atomic chain was swallowed by its own head and took on the form of a spinning ring. This architectural vision gave him the clue he needed for description of a whole group of cyclic or ring compounds that still play a crucial role in organic chemistry

There seems to be direct link between truly creative intelligence and the ability to dilute consciousness, to cut mental corners and practise unusual, lateral thinking in what amounts almost to a state of trance. All the most profound insights seem to flow from breaches in the barrier between waking thought, which tends to be conservative, and dream logic, which is essentially liberal. It cannot be purely accidental that Coleridge composed “Kubla Khan” in his sleep or that Mozart found his best musical inspiration rising like dreams, quite independent of his will.

It seems that, under conditions of dissociation, we have the chance to tune in directly to some of the world’s basic rhythms, to become aware of the pattern behind the process. To know, in the words of Keats, that “what the imagination seizes as beauty, must be truth.”

What Are Russia's Top 5 Anti-Satellite Systems?

© Flickr/NASA Goddard Space Flight Center

— Ekaterina Blinova | Thursday February 15, 2024

Russia has effective means to thwart adversary satellites, including arms based on new physical principles. What are they? Moscow trashed the groundless rumors of its alleged efforts to deploy a nuclear anti-satellite system in space on February 15.

A day earlier, mainstream US media claimed that Washington had informed Congress and its European allies about Russia's work on a new, space-based nuclear weapon designed to undermine the US satellite network.

A new bugaboo about Russia's supposed plans to destroy American satellites with nuclear arms is aimed at ramming a $60 billion funding package for Ukraine through US Congress, military analyst and editor-in-chief of the National Defense magazine Igor Korotchenko told Sputnik on Thursday. Even though the package in question was earlier passed in the US Senate as part of a $95 billion bill, the chances of the House approving the legislation is considered slim.

According to Korotchenko, Russia has cheaper and more effective means of anti-satellite warfare than those that Washington accuses it of developing.

“This is a question of approaches. The fact is that the deployment of nuclear weapons in space is ineffective in terms of its use, especially given that Russia has much simpler and cheaper means to disable, in the event of hostilities, a significant part of the US satellite constellation," the expert underscored.

Sputnik has taken a look at the systems that could do the job.

The Nudol System

On November 15, 2021, Moscow conducted a direct-ascent hit-to-kill anti-satellite (ASAT) test using the A-235 Nudol Anti-Satellite System. The test shot down an old Soviet reconnaissance satellite launched back in 1982.

The A-235 Nudol is an improved modification of the A-135 Amur strategic missile defense system. The missile can hit a target at a distance of up to 1,500 kilometers (versus 850 kilometers for the A-135), while its interception speed is increased to Mach 10 (versus Mach 3.5 for the A-135).

In contrast to its predecessor, the A-235 May Use Kinetic Force, not nuclear or high-explosive fragmentation, to destroy the target.

The development of the A-235 Nudol started in 1985-1986 and was carried out in compliance with international ballistic missile agreements existing at the time. The weapon was designed to become the first Soviet mobile missile defense system capable of intercepting intercontinental-range missiles, spacecraft and satellites operating at high orbits.

Immediately after the Cold War, the development of the A-235 was suspended and restarted in 2011 by Almaz-Antey, nine years after the Bush administration unilaterally terminated the Antiballistic Missile Treaty (ABM) in 2002.

The system has been tested several times since 2014; however, in November 2021 the missile was fired at a specific moving space target and eventually destroyed it, causing a fuss in the Pentagon.

Nanosatellites: Nivelir, Burevestnik and Numismat

The development of Russia's secretive project Nivelir ("Leveler") has reportedly been carried out by the Central Scientific Research Institute of Chemistry and Mechanics Named after D.I. Mendeleyev since 2011.

The endeavor supposedly envisaged building small satellites designed to inspect other satellites in space. The first three satellite-inspectors were reportedly attached to three communications satellites launched between 2013 and 2015.

According to other sources, Russia has been experimenting with satellite inspectors since 2017. The satellites maneuvered in orbit, moving away from each other and then getting closer. In 2019, the Cosmos-2535 and Cosmos-2536 devices were launched. Their goal was to study the impact of "artificial and natural factors of outer space" on Russia's space devices and to develop "technology for their protection."

It is understood that the idea behind placing satellite-inspectors in specific orbits is to affect "adversary" satellites in various ways, including "inspecting" them, i.e. collecting all necessary information on them.

The Burevestnik Project (not to be confused with the ballistic missile) is reportedly being developed on the basis of the Nivelir project. The spacecraft is allegedly capable of tracking many fast-moving objects in space at once, including missiles and satellites in high orbits. The so-called Numismat ("Numismatist", or "coin collector") radar systems for near space is also said to be developed in Russia. These are also "nanosatellites" that are difficult to detect.

The Kontakt System

The USSR started to develop the 30P6 Kontakt ("Contact") system in 1983. The 79М6 munition – a three-stage rocket – was supposed to be mounted on the MiG-31D fighter-interceptor.

Launched from an airplane at an altitude of 15 kilometers the munition was designed to fire a fragmentation warhead into space. It was assumed that the Kontakt system would be a stealth and inexpensive means of destroying enemy satellites.

A series of tests ended up in an allegedly successful launch that took place on July 26, 1991. An experimental aircraft Izdeliye "07-2" (MiG-31D) armed with the 79M6 missile suspension took off from the Sary-Shagan airfield over the Bet-Pak Dala training grounds. It is known that two stages of the rocket were solid-propelled, and the last stage, which controlled the final guidance of the kinetic warhead at the target, was liquid.

The MiG-31 fighter was picked since it can fly at extreme altitudes in the stratosphere while carrying large non-standard missiles and firing all types of weapons at maximum altitude. In addition, the MiG-31's capabilities allow it to carry large-caliber anti-satellite weapons.

The secretive project was frozen after the collapse of the USSR, but in 2009, Russia announced the resumption of work on Kontakt using the MiG-31. According to the media, the Russian military is currently testing the upgraded version of the system.

The Tirada Electronic Warfare System

According to the Russian Ministry of Defense, the Tirada-2S Radio-Electronic Communication Suppression System is capable of electronically jamming satellite communications with complete disabling. In this case, satellites can be deactivated directly from the Earth's surface.

There is little information about the system's specifications in the public domain. The system was first mentioned by the deputy head of the 46th Central Research Institute of the Russian Ministry of Defense Oleg Achasov in 2017. Achasov said that the Tirada-2S mobile complex to jam communication satellites was created as part of the weapons modernization program for 2018-2027.

A year later, at the international military-technical forum "Army-2018" a contract was signed for the supply of an automated satellite communication jamming station "Tirada 2.3" to the Russian military.

In 2020, the mysterious electronic warfare was tested by the personnel of the Central Military District in the Sverdlovsk region. The Ministry of Defense noted at the time that "the crews of the Tirada complex trained the detection of satellite communication channels that provide a cycle of combat control and data transmission by reconnaissance aircraft and sabotage groups of a mock enemy. Having identified the channel and belonging to a space satellite, the Tirada crews conducted suppression and set up controlled interference to prevent the signal from passing through."

The Peresvet Laser System

On March 1, 2018, Russian President Vladimir Putin first mentioned Russia's laser weapon for air defense and anti-satellite warfare, the Peresvet, during his address to the Federal Assembly.

The Peresvet, named after a medieval Orthodox warrior monk Alexander Peresvet, entered experimental combat duty in the Russian Armed Forces in December 2018. By February 2019, the Russian president announced the laser installations had confirmed their unique characteristics along with the Kinzhal hypersonic missiles.

According to Russian military observers, the laser system is capable of blinding the optical systems of reconnaissance satellites, drones, and aircraft. The Peresvet project remains classified, so it's hard to say what type of laser it is equipped with. Some scientists believe that this is a nuclear-pumped laser, others believe that the complex uses an oxygen-iodine laser (OIL) with iodine explosive pumping.

The aforementioned systems are just a few of those potentially developed by the Russian military-industrial complex, indicating that Russia is capable of using its decades-long scientific and technological potential to ensure the nation's security in the event of a large-scale conflict.

Shostakovich

Origins and early years Dmitri Shostakovich (Russian: Дми́трий Дми́триевич Шостако́вич) ( Saint Petersburg , September 12 , 1906 (Julia) - Moscow , August 9 , 1975 ), full name with patronymic Dmitri Dmitrievitch Shostakovich , was a composer and pianist Russian of the Soviet period . He started on the piano of his mother's hand. Later, from 1919 to 1925, he studied piano and composition at the Petrograd Conservatory. He composed his first symphony in 1925, premiered on May 5, 1926 in Berlin . The Soviet government of the time commissioned the second symphony for the tenth anniversary of the October Revolution . From 1925 to 1935 he wrote several avant-garde compositions. His operas El Nas in 1930 and Ledi Màkbet Mtsènskogo Uiezda in 1934 stood out. The latter caused a scandal in New York City and strong criticism from the Stalinist government, which banned it. Over time, Shostakovich regained favor with the Soviet government, notably with his Fifth Symphony in 1937. During World War II he wrote about the heroism of the Soviet people. His seventh symphony was written during the siege of Leningrad . After the war, from 1948, he suffered the persecution of Andrei Zhdanov and could not write freely until the death of Stalin in 1953. He died on August 9, 1975, leaving a legacy of fifteen symphonies, fifteen concertos, two operas, three dozen film pieces and many works of chamber music, including fifteen string quartets, and many others minor works and songs. Born on Podolskaya Street in Saint Petersburg ( Russian Empire ), Shostakovich was the second of three children of Dmitri Boleslavovich Shostakovich and Sofiya Vasílievna Kokoúlina. Shostakovich's paternal grandfather, originally surnamed Szostakowicz, was of Catholic Polish descent (his family roots go back to the region of the city of Vileyka in present-day Belarus ), but his immediate ancestors came from Siberia . A Polish revolutionary in the January Uprising of 1863–1864, Bolesław Szostakowicz went into exile in Narym (near Tomsk ) in 1866 during the repression that followed Dmitri Karakózov's assassination attempt on the Tsar Alexander II . When his period of exile ended, Szostakowicz decided to remain in Siberia , where he became a successful banker in Irkutsk and raised a large family. His son, Dmitri Boleslavovich Shostakovich, the composer's father, was born in exile in Narym in 1875, studied physics and mathematics at St. Petersburg University and graduated in 1899. He then went to work as an engineer with Dmitri Mendeleyev at the Bureau of Weights and Measures in St. Petersburg. In 1903, he married Sofiya Vasílievna Kokoúlina, one of six children born to a Siberian who also immigrated to the capital. House in which Shostakovich was born (now School no. 267), with a commemorative plaque on the left. Her son, Dmitri Dmitrievich Shostakovich, showed great musical talent after he began taking piano lessons with his mother at the age of nine. On several occasions, he showed a remarkable ability to remember what his mother had played in the previous lesson and was "caught in the act" of playing music from the previous lesson while pretending to read different music placed in front of him. In 1918, he wrote a funeral march in memory of two leaders of the Russian Constitutional Democratic Party murdered by Bolshevik sailors. In 1919, at the age of 13, Shostakovich was admitted to the Petrograd Conservatory, then directed by Aleksandr Glazunov , who closely monitored his progress and supported him. He studied piano with Leonid Nikoláiev after a year in the class of Elena Rózanova, composition with Maximilián Steinberg and counterpoint and fugue with Nikolái Sokolov, of whom he became a friend. He also attended the musical history classes of Aleksandr Ossovski. Steinberg tried to guide it in the way of the great Russian composers, but was disappointed to see him "wasting" his talent imitating Igor Stravinsky and Sergei Prokófiev . Shostakovich also suffered from his apparent lack of political zeal, and initially failed his Marxist methodology exam in 1926. His first major musical achievement was the First Symphony (premiered in 1926), written as his graduation piece in the age of 19 years. This work attracted the attention of Mijaíl Tujachevski , who helped him find accommodation and work in Moscow , and sent a driver in "a very elegant car" to take him to a concert. Beginning of his career After graduation, Shostakovich initially embarked on a dual career as a concert pianist and composer, but his dry playing style was often unappreciated (his American biographer, Llorer Fay, comments on his "emotional restraint » and «fascinating rhythmic impulse». He won an 'honorable mention' at the first Frédéric Chopin International Piano Competition in Warsaw in 1927 and attributed the disappointing result to suffering from appendicitis and the all-Polish jury. He had his appendix removed in April this year. After the competition, Shostakovich met the conductor Bruno Walter , who was so impressed with his First Symphony that he conducted it at its premiere in Berlin that same year. Leopold Stokowski was equally impressed and directed the play in its premiere in the United States the following year in Philadelphia . Stokowski also made the first recording. Shostakovich concentrated on composition thereafter, and soon limited his performances mainly to his own works. In 1927, he wrote his Second Symphony (subtitled October ), a patriotic piece with a pro-Soviet choral ending. Due to its experimental nature , as with the later Third Symphony , it was not acclaimed by critics with the enthusiasm received in the First . This year also marked the beginning of Shostakovich's relationship with Iván Sollertinsky , who remained his closest friend until the latter's death in 1944. Sollertinsky introduced the composer to the music of Gustav Mahler , which had a strong influence on him from his Fourth Symphony onwards. While writing the Second Symphony , Shostakovich also began work on his satirical opera The Nose , based on the story of the same name by Nikolai Gogol . In June 1929, against the composer's wishes, the opera was performed and fiercely attacked by the Russian Association of Proletarian Musicians (RAPM). Its stage premiere on 18 January 1930 opened to generally poor reviews and widespread misunderstanding among musicians. In the late 1920s and early 1930s, Shostakovich worked at TRAM, a proletarian youth theater . Although he did little work on this publication, it protected him from ideological attack. Much of this period was spent writing her opera Lady Macbeth of Mtsensk , which was first performed in 1934. It was an immediate success, both popularly and officially. It was described as "the result of the general success of socialist construction, of correct party politics", and as an opera that "could only have been written by a Soviet composer educated in the best tradition of Soviet culture". Shostakovich married his first wife, Nina Varzar, in 1932. Difficulties led to divorce in 1935, but the couple soon remarried when Nina became pregnant with their first daughter, Galina. Between October 1950 and March 1951 he composed the 24 Preludes and Fugues op. 87, dedicated to the pianist Tatiana Petrovna Nikolaieva . During the period that Shostakovich was composing these pieces, Nikolayeva called him every day and went to her house to watch him play what he had re-composed. In 1952, the complete 24 preludes and fugues were performed for the first time, in the city of Leningrad, by Nikolayeva. Read the full article
