МОСКВА, 26 ноя — РИА Новости. Ученые Самарского университета совместно с коллегами из РАН разработали новый способ создания оптических элементов, с помощью которого можно усовершенствовать устройства для передачи данных по лазерному лучу в атмосфере и биомедицинские аппараты. Результаты научного исследования опубликованы в журнале "Optics Express". Российские ученые разработали новый подход для построения метаповерхностей, на основе которых можно создать оптические элементы для устройств, позволяющих управлять поляризацией и фазой электромагнитных волн, а также создавать световые поля с неизученными ранее свойствами, в том числе уникальные лазерные пучки. “Мы разработали оптический элемент на основе метаповерхности и продемонстрировали его эффективную работу: одновременное формирование и фокусировка специального лазерного пучка с вихревой структурой поляризации. В фокусе такого пучка световая энергия частично распространяется в направлении к источнику, что невозможно при фокусировке классических лазерных пучков”, — прокомментировал автор исследования, доцент кафедры технической кибернетики Самарского университета Дмитрий Савельев. Ученый также отметил, что метаповерхности более высокого порядка обеспечивают большой общий обратный поток энергии. То есть лазерные пучки, сформированные с помощью поляризующих элементов, устойчивы к помехам, возникающим при передаче информации в различных турбулентных средах, например, в атмосфере Земли. “Существует способ передачи данных по лазерному лучу в атмосфере, но он подвержен помехам. С помощью разработанных метаповерхностей можно создавать особые лазерные пучки, которые будут более устойчивы к возникающим помехам в атмосфере, таким как ветер, туман, дождь. Таким образом можно передавать данные на большее расстояние с меньшими потерями”, — рассказал соавтор исследования, научный сотрудник Института систем обработки изображений РАН Сергей Дегтярев. Ученый объяснил, что реализованные метаповерхности позволяют создавать новые типы оптических ловушек. Они работают как пылесос: обратный поток энергии возле оптической оси заставляет частицы двигаться к источнику. Кроме того, по словам экспертов, за счет объединения в одном элементе поляризатора с фокусатором удается создавать большой обратный поток энергии вблизи оптической оси. Это поможет усовершенствовать оптические пинцеты, лазерную резку и гравировку в биологии, медицине и обработке материалов, а также уменьшить количество оптических элементов в устройствах. "Управление поляризацией позволяет создавать световые поля с новыми свойствами. Меняя структуру лазерного пучка, можно изменять характер воздействия на объект, а это очень актуально для лазерной резки и гравировки в обработке материалов", — отметил Дмитрий Савельев.

Space science next year will be rocketed forward with missions to the Moon, asteroids, Mars and the successor to the Hubble Space Telescope coming online. Why it matters: The data sent back to Earth from these upcoming missions will help scientists learn more than ever before about objects in the solar system and far beyond it.

They include: Mars: The European Space Agency and Russia are planning to launch their joint ExoMars lander and rover to the surface of the Red Planet in September. It will join NASA's Perseverance and Curiosity rovers on the Martian surface. Both are expected to continue their work next year. Asteroids: NASA's Psyche mission is due to launch in August 2022 on a mission to explore a strange, metal-dominated asteroid that may have once been part of the core of a long-dead planet. NASA's DART mission is also expected to arrive at its asteroid target next year in the hopes of slamming into it and figuring out just what it would take to throw a dangerous space rock off of a collision course with Earth. The Moon: NASA is expected to launch the first flight of its Space Launch System mega-rocket on a trip around the Moon, and the space agency plans to load it with scientific experiments. The rocket will carry a clutch of small satellites that will investigate water in the lunar environment. Other nations like Japan, Russia and India are also aiming to send missions to the Moon next year. Russia's mission — called Luna-25 — is https://www.russianspaceweb.com/luna_glob_lander.html designed to search for water near the south pole of the Moon. NASA's James Webb Space Telescope — the successor to the Hubble — is also expected to be up and running starting early in 2022. https://www.axios.com/nasa-james-webb-space-telescope-55169933-6558-4240-9d05-fda169711883.html The JWST is tasked with no less than piecing together the early history of the universe using its powerful, sensitive instrumentation to see the light of some of the universe's first galaxies and cut through dust to see newborn stars. The space telescope is also expected to parse the atmospheres of distant alien planets. Between the lines: As all of these missions launch and arrive at their targets, astronomers and planetary scientists will also be shoring up their goals for the coming years. https://www.axios.com/astronomys-field-survey-release-f2abc6ce-6e57-4968-a1f4-fb79a908bd7b.html In 2021, an influential report laid out the major priorities for the next decade of astronomy and astrophysics, centering on the idea that scientists should strive to find a potential twin of Earth orbiting a star like the Sun. 2022 will be the year that researchers and agencies like NASA continue to find ways to prioritize those goals and others laid out by the scientific community this year. What to watch: China is expected to continue collecting data from ongoing robotic missions to the Moon and Mars. The nation is also expected to complete its space station in the next year or so, providing a new platform for possible scientific research above Earth. Like this article?

Mabuhay Asgardians! Ito si Igor Ashurbeyli, Ang lumikha ng Asgardia, ay malugod kayong tinatanggap sa aking opisina sa Moscow. Dito ang lugar kung saan ang ideya ng paglikha ng unang estadong pang kalawakan sa kasaysayan ng tao ay binuo. At dahil ngayon ang ikatlong buwan mula nang ihayag namin ang simula ng politikal na pundasyon ng Asgardia, ito rin, ang ika-12 ng Oktubre 2016, ang unang araw ng kalendaryo ng Asgardia. Na sa loob lamang ng 40 oras, mahigit sa 100,000 aplikasyon sa Asgardia ang naipasa at sa loob ng dalawang buwan, ang bilang ay tumaas sa halos mahigit kalahating milyon. Nitong nakaraang ika-12 ng Disyembre, nanawagan ako sa inyo na iberipika ninyo ang inyong datos, at sa loob lamang ng dalawang linggo ay mahigit sa 100,000 Asgardians ang nagkumpirma ng kanilang personal na datos at binigyan ako ng awtorisasyon upang maging kinatawan ng Asgardia bilang pangulo ng bansa. Personal akong nagpapasalamat sa bawat isa sa inyo sa tiwalang inyong ipinagkaloob. Ngayon, ang Asgardia ay binubuo ng mamamayan na nagmula sa higit dalawang daang bansa. Ito ay ang globo; kung saan ang bawat nasyon ay gumagamit ng iba't ibang kalendaryo. Hindi natin maaaring gamitin ano man sa mga kalendaryong ito dahil ang nasyong pang kalawakan ay may ibang pamumuhay kaysa sa mundo. Ang Asgardians ay gumagamit ng higit sa 100 wika sa buong daigdig. Ang Ingles ay ang pinaka popular sa lahat. Ito ang ginagamit ng higit sa 48 porsiyento ng Asgardians. Kinakausap ko kayo ngayon gamit ang aking lokal na lenggwahe,sa ruso, kung saan ika-walo sa ginagamit na lenggwahe sa Asgardia. kakaiba para sa akin na tinatawag na ‘Ama ng Nasyon’ ngunit nang maihayag na 70 porsyento ng Asgardians ay kabataan na may edad na 18 hanggang 35 taong gulang, aking napagtanto na ang pangunahing gawain natin ay protektahan ang ating planeta at ingatan ang ating tahanan para sa mga susunod na henerasyon. Sa bilog na lamesang ito, kung saan nagsisimbulo ng prinsipyo ng kalayaan at pagkakapantaypantay sa Asgardia, kami ay nagpulong at pinag-usapan ang kasalukuyang kaganapan at ang hinaharap. Sa taong 2017, kung saan ang unang taon ng Asgardia, marami tayong gawain na kailangang tapusin. Kailangan nating iendorso ang deklerasyon ng pagkakaisa, pagpasa ng konstitusyon, iboto ang mga mamumuno, italaga kung saan ang ating pandaigdigang lokasyon, pumili ng watawat, ang pambansang himig, ang ating sagisag at marami pang iba. Tayo rin ay naghahanda para sa paglunsad ang ating unang Satellite. Sa likod ko, makikita mo ang orasan na simbolo pamumuhay sa mundo. At sa gitna ng lamesang ito, mayroong isang sinaunang kabibe na nabuhay milyon-milyong taon ang nakalipas. Ito ay ang landas ng ebolusyon ng tao. At sa anumang panahon, ang mahuhusay na tao ay tumitingin sa kalangitan ng may pag-asa at pangarap ng isang masayang mundo at bagong bansa sa kalawakan. Hindi man masasabing ang mga Asgardians ng pinakamahuhusay na tao, tayo ang mga nilalang ng hinaharap. At ang ating motto, kung saan umaasa ako na inyong tatanggapin ngayon, ay: "Isang Sangkatauhan at Pagkakaisa" Isang mainit na pagyakap para sa bawat isa sa inyo. ---------------------------- (English Translation) Hello Asgardians! Igor Ashurbeyli, the Founding Father of Asgardia, welcomes you to his office in Moscow. This is exactly where the idea of creating the first Space State in the human history came to live. And since today is exactly three months since we announced the start of Asgardia’s foundation politically, it is also today that I name October 12th 2016 to be the day number one of the new Asgardian Calendar. In onlya 40 hours, more than 100,000 applications to Asgardia have been submitted and then, in two months, the numbers skyrocketed to over half a million. On December 12th, I asked you to start verifying your data, and in only two weeks more than 100,000 of you Asgardians have confirmed your personal data and authorized me to represent Asgardia in the Earthly world as the Head of the Nation. I personally thank each and every one of you for the trust you placed in me. Today, Asgardia’s home for citizens for more than 200 countries. This is the whole globe; where different nations adhere to different calendars. We cannot give preference to any of those since our Space Nation has to rise above the commotion of the Earthly life; above it’s borders and earthly religions. Asgardians speak more than 100 languages of the world. English was the most popular choice among those. It is spoken by over 48% of Asgardians. I am addressing you today in my native language, in Russian, which ranks 8th on the hierarchy of Asgardian languages. It was strange for me to be called the ‘Father of the Nation’ but when it became known that 70% of Asgardians are the young people aged between 18 and 35 years old I realized that our main task is indeed to protect planet Earth and preserve our common home for generations to come. At this round table, which symbolizes Asgardia’s principles of freedom and equality the country's current affairs and its future development are discussed. In 2017, in the first Asgardian year, we have a lot to accomplish. We need to endorse the ‘Declaration of Unity, approve the Constitution, elect the governing bodies, define their locations on the Earthly continents, select a flag, the national anthem, the insignia and many other things. We are also working on the first Asgardia satellite launch. In the background, you can see the clock which symbolizes the transience of Earthly life. And in the middle of the table, there is an ancient shellfish which dates back millions of years. This is the evolutionary path of a human being. And yet, in any era, the best of people looked at the stars with hope and dreamed of a happy new world and a new country in the sky. Even though we, Asgardians, may not be the best of all people but, for sure, we are the people of the future. And our motto, which I hope you will accept and endorse today, is: “One humanity – one unity”. I embrace you and every one of you. https://www.youtube.com/watch?v=PMP51UQlmAg

in the beginning it was al about receiving the good signals true our brain.. mostly by night and in caves.. then came the evolution of deciding.. species could decide during the day and receive by night or rest.. when humans became powerful due natural resources their thinking and evolution went the most luxury way to survive the earth.. so they needed no longer the receiver part of their brain.. now.. after many catastrophes and very difficult times we search again for that sender and receiver part.. - but the problem is that humans have discarded the natural earth and its natural and magnetic signals.. so that we have lost the sane decisions from the natural world and have exchanged them for electronics and weird spiritual ways.. - this makes us far more advanced then ever before.. but we will pay a price for it.. namely the extinction of humans able to connect directly with the natural world.. to name the most important ones wild tribes, original populations and spiritual leaders.. - if we ever should go to space then we have to be sure to take our foundations with us.. and by that i mean a piece of the natural world in its natural environment.. so that it can adopt to space and not be forced by humans.. Grtz, Dirk.

Les deseo una feliz navidad a todos los hermanos de Asgardia.

one thing we can observe and call a fact is that with democracy the decision makings are slower because of internal discussions and agreements.. if we move to space then that is not the way to do it for all things.. we have to categorize which things need fast solutions and which need more time and the lot in between.. maybe some point-priority system from 1 to 10 as example would make it more to the point.. Grtz, Dirk.
