From the knowledge of the crystalline structure, the temperatures, pressures, and other aspects of formation can often be deduced. The molecular components and crystalline structures are determined, allowing individual components of a mixture, such as an oxide and sulfide, to be identified. While elemental analysis obtained by spectroscopy or wet chemistry can identify the elemental constituents of a component or mixture, XRD provides far more information. The diffracted peak positions and intensities from a particular material phase serve as a fingerprint that can be compared to a database of reference patterns to identify a phase or phases of solids, powders, thin films, or suspensions.

![]() Since they absorb all the light around them, we can't see black holes directly, but the surrounding glowing gas reveals a telltale circular shadow in the central region surrounded by a bright ring. Size comparison of the two black holes M87* and Sagittarius A* - Credit: EHT collaboration One at the center of Galaxy M87 and three years later in 2022 the seemingly tiny one, known as Sagittarius A* at the heart of our own Galaxy, the Milky Way : Some black holes power the brightest known objects in the universe, known as quasars. But not all black holes fit this description, because light can still be emitted from the region outside the event horizon. "Gargantua" seen in the Movie InterstellarĪnd then in 2019, the world was thrilled by the first photos of real black holes using the Event Horizon Telescope. We tend to imagine black holes as black spheres in the middle of space. The 2014 film Interstellar featured a black hole that blew the minds of even seasoned scientists. Within a century of Einstein's theory, the black hole theory was proven and already found its way into pop culture. Later Roger Penrose and Stephen Hawking worked on this theory until 2020 a shared noble prize was awarded to Penrose for "the discovery that black hole formation is a robust prediction of the general theory of relativity". ![]() In 1916 Karl Schwarzschild predicted them to be a theoretically possible solution to Einstein's general theory of relativity, but Einstein himself thought of them as non-physical. Gravity is the ultimate victor in the life story of any star, leaving behind the exotic end states of white dwarfs, neutron stars, and black holes. Additionally, scientists believe that simulation of unusual states of matter will be an important early application of quantum computing, and there are few more unusual states of matter than those found in the vicinity of black holes.A common misconception is, that Albert Einstein was the first to think about black holes, but in fact, first John Michell in 1783 and later Pierre-Simon Laplace in 1796 suggested their existence for the first time. Stars are the crucibles of heavy element creation, and the chaotic regions of their birth are being understood though long wavelength observations. "One day, we may even be able to use rotating black holes as quantum computers by sending photons on the right trajectory around these ghostly astronomical bodies," Racorean concludes. This topic may seem esoteric, but it could have practical applications. "If we find that the X-ray polarisation changes with distance from the black hole, with those in the central region being least polarised, we will have observed entangled states that can carry quantum information," says Racorean. These will investigate the polarisation of all X-rays found in space, including those emitted close to black holes. ![]() Two space probes with the same mission will be launched around 2022: the Imaging X-ray Polarimetry Explorer (IXPE) by NASA, and the X-ray Imaging Polarimetry Explorer (XIPE) by the European Space Agency. The final proof will come when the properties of X-rays near spinning black holes are observed, which could happen in the next decade. Thus far, however, this process is only a prediction. "It now seems that the curvature of spacetime around a black hole will play the same role as this apparatus." "Lab-based researchers already use beam splitters and prisms to entangle these properties in X-ray photons and process quantum information," says Racorean. Each of these can encode a qubit (quantum bit) of information, the standard information unit in quantum computing. The photons that make up the X-rays have two properties: polarisation and orbital angular momentum. ![]() Powerful forces acting on accretion disks raise their temperature so they emit X-rays, which can act as carriers of quantum information. Material that gets close to a rotating black hole but does not fall into it will aggregate into a circular structure known as an accretion disk. If the star that forms it rotates, as most stars do, the black hole will also spin. Some may collapse into a point with essentially no volume and infinite density, with a gravitational field that not even light can escape from: this is a black hole. ![]() When stars come to the end of their lives, they can collapse in on themselves under their own weight, becoming denser and denser. The term 'black holes' is widely known, but not everyone knows exactly what they are. ![]() ![]() ![]() ![]() This live preview feature provides you with instant feedback, showing you exactly how your design will look as you work and experiment with code.

The commune movement started in the 10th century, with a few earlier ones like Forlì (possibly 889), and gained strength in the 11th century in northern Italy, which had the most urbanized population of Europe at the time. When a commune formed, all participating members gathered and swore an oath in a public ceremony, promising to defend each other in times of trouble, and to maintain the peace within the city proper. At their heart, communes were sworn allegiances of mutual defense. However, there were rural communes, notably in France and England, that formed to protect the common interests of villagers. In most cases the development of communes was connected with that of the cities. Thus towns formed communes which were a legal basis for turning the cities into self-governing corporations. Because much of medieval Europe lacked central authority to provide protection, each city had to provide its own protection for citizens - both inside the city walls, and outside. The walled city provided protection from direct assault at the price of corporate interference on the pettiest levels, but once a townsman left the city walls, he (for women scarcely travelled) was at the mercy of often violent and lawless nobles in the countryside. Such charters were often purchased at exorbitant rates, or granted, not by the local power, but by a king or by the emperor, who came to hope to enlist the towns as allies in order to centralize power. This was a long process of struggling to obtain charters that guaranteed such basics as the right to hold a market. Such townspeople needed physical protection from lawless nobles and bandits, part of the motivation for gathering behind communal walls, but also strove to establish their liberties, the freedom to conduct and regulate their own affairs and security from arbitrary taxation and harassment from the bishop, abbot, or count in whose jurisdiction these obscure and ignoble social outsiders lay. Other towns were simply market villages, local centers of exchange. Such towns were also founded in the Rhineland. The sites for these ab ovo towns, more often than not, were the fortified burghs of counts, bishops or territorial abbots. In the Low Countries, some new towns were founded upon long-distance trade, where the staple was the woolen cloth-making industry. In central and northern Italy, and in Provence and Septimania, most of the old Roman cities had survived-even if grass grew in their streets-largely as administrative centers for a diocese or for the local representative of a distant kingly or imperial power. When autonomy was won through violent uprising and overthrow, the commune was often called conspiratio (a conspiracy) ( Italian: cospirazione).ĭuring the 10th century in several parts of Western Europe, peasants began to gravitate towards walled population centers, as advances in agriculture (the three-field system) resulted in greater productivity and intense competition. Ultimately, the Proto-Indo-European root is *mey- (to change, exchange). They come from Medieval Latin communia, plural form of commune (that which is common, community, state), substantive noun from communis (common). The English and French word "commune" ( Italian: comune) appears in Latin records in various forms. At the same time in Germany they became free cities, independent from local nobility. They had greater development in central-northern Italy, where they became city-states based on partial democracy. ![]() These took many forms and varied widely in organization and makeup.Ĭommunes are first recorded in the late 11th and early 12th centuries, thereafter becoming a widespread phenomenon. Medieval communes in the European Middle Ages had sworn allegiances of mutual defense (both physical defense and of traditional freedoms) among the citizens of a town or city. ![]() SOLE Defensive towers at San Gimignano, Tuscany, bear witness to the factional strife within communes.

Important Update! The HCPRO-SD380 is now a 4-in-1 selectable HD-over-Coax security camera and has a built-in audio surveillance microphone. This HD security camera easily mounts to ceiling tiles and other ceiling materials. A very small cone / pinhole lens peeks out of the side of the smoke detector plastic housing and is virtually undetectable and makes this an excellent spy cam. This professional spy camera is completely hidden in the smoke detector housing. smoke detectors are installed high on the walls or ceilings hence giving an advantageous position for recording videos.The HCPRO-SD380 smoke detector security camera is an excellent choice for indoor covert surveillance. The second main reason is because of their height advantage. ” Since they are the most common appliances in offices and at home, it is easy to conceal a camera without arousing suspicion.” The number 1 reason proposed by majority of customers: What Makes a Smoke Detector Camera the Best Spy Cam?
