A corpus-wide machinelearning analysis of early modern astronomic tables - Abstract: "Understanding the evolution and dissemination of human knowledge over time faces challenges due to the abun-dance of historical materials and limited specialist resources. However, the digitization of historical archives presentsan opportunity for AI-supported analysis. This study advances historical analysis by using an atomization-recomposition method that relies on unsupervised machine learning and explainable AI techniques. Focusing on the“Sacrobosco Collection,” consisting of 359 early modern printed editions of astronomy textbooks from Europeanuniversities (1472–1650), totaling 76,000 pages, our analysis uncovers temporal and geographic patterns inknowledge transformation. We highlight the relevant role of astronomy textbooks in shaping a unified mathematicalculture, driven by competition among educational institutions and market dynamics. This approach deepens ourunderstanding by grounding insights in historical context, integrating with traditional methodologies. Case studiesillustrate how communities embraced scientific advancements, reshaping astronomic and geographical views andexploring scientific roots amidst a changing world." https://lnkd.in/eRebd8EQ Oliver Eberle 1,2, Jochen Büttner2,3, Hassan el-Hajj2,4, Grégoire Montavon 1,2,5,Klaus- Robert Müller 1,2,6,7*, Matteo Valleriani 2,4,8,9

THE CONSTRUCT OF TIMESPACE The concept of timespace is a theoretical framework that combines the dimensions of time and space into a single continuum. It’s often used in discussions related to physics and cosmology, especially in theories like Einstein’s theory of general relativity and concepts like spacetime. In this framework, time and space are intertwined, and events in the universe occur within this unified framework, allowing for a more comprehensive understanding of the universe’s structure and dynamics. Gravity, within the context of time-space energy and matter, can be understood as the curvature of the fabric of spacetime caused by the presence of mass and energy. According to Einstein’s theory of general relativity, massive objects such as planets, stars, and galaxies distort the fabric of spacetime around them, creating a gravitational field. This curvature of spacetime affects the motion of other objects within its vicinity, causing them to move along curved paths dictated by the geometry of spacetime. In essence, gravity is the manifestation of the interaction between matter (mass and energy) and the fabric of spacetime, resulting in the force that we observe as gravity. The concept of gravity, as described by Einstein’s theory of general relativity, relies on the abstract constructs of spacetime, rest energy, and mass. These constructs are theoretical frameworks developed to explain the behavior of the universe at fundamental levels. Spacetime, for example, is a mathematical model that unifies space and time into a single continuum, allowing us to describe how objects move through the universe in the presence of mass and energy. Rest energy, as described by (E = mc^2), demonstrates the equivalence between mass and energy, suggesting that mass can be considered a form of energy even when at rest. This construct plays a crucial role in understanding the relationship between mass and gravity in general relativity. Fortunately, the effects of spacetime curvature apparently become more noticeable in extreme conditions, such as near massive galactic objects like black holes or when objects are moving at very high speeds. For example, near a #black_hole, where the gravitational field is exceptionally strong, the curvature of #spacetime is incredibly pronounced, leading to dramatic effects such as time dilation and #gravitational_lensing. So, in short, spacetime curvature due to mass and energy occurs at all speeds, but its effects become more apparent under extreme conditions or at high velocities. While these constructs may seem abstract, they provide remarkably accurate descriptions of observed phenomena, from the motions of planets and galaxies to the bending of light around massive galactic objects.

📃Scientific paper: Cluster analysis of the Roma-BZCAT blazars Abstract: Based on the collected multiwavelength data, namely in the radio (NVSS, FIRST, RATAN-600), IR (WISE), optical (Pan-STARRS), UV (GALEX), and X-ray (ROSAT, Swift-XRT) ranges, we have performed a cluster analysis for the blazars of the Roma-BZCAT catalog. Using two machine learning methods, namely a combination of PCA with k-means clustering and Kohonen's self-organizing maps, we have constructed an independent classification of the blazars (five classes) and compared the classes with the known Roma-BZCAT classification (FSRQs, BL Lacs, galaxy-dominated BL Lacs, and blazars of an uncertain type) as well as with the high synchrotron peaked blazars (HSP) from the 3HSP catalog and blazars from the TeVCat catalog. The obtained groups demonstrate concordance with the BL Lac/FSRQ classification along with a continuous character of the change in the properties. The group of HSP blazars stands out against the overall distribution. We examine the characteristics of the five groups and demonstrate distinctions in their spectral energy distribution shapes. The effectiveness of the clustering technique for objective analysis of multiparametric arrays of experimental data is demonstrated. ;Comment: Accepted for publication in Research in Astronomy and Astrophysics Continued on ES/IODE ➡️ https://etcse.fr/quBxl ------- If you find this interesting, feel free to follow, comment and share.

Fresh Wind Blows From Historical Supernova | University of Tokyo Fresh wind blows from historical supernova Elusive temporary star described in historical documents recreated using new computer model, shows it may have recently started generating stellar winds. A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary 'guest star,' now labeled supernova (SN) 1181, which was recorded in historical documents in Japan and elsewhere in Asia. However, after the star dimmed, its location and structure remained a mystery until a team pinpointed its location in 2021. Now, through computer modeling and observational analysis, researchers have recreated the structure of the remnant white dwarf, a rare occurrence, explaining its double shock formation. They also discovered that high-speed stellar winds may have started blowing from its surface within just the past 20-30 years. This finding improves our understanding of the diversity of supernova explosions, and highlights the benefits of interdisciplinary research, combining history with modern astronomy to enable new discoveries about our galaxy. https://lnkd.in/dsiwTgWq

Notes on three space time, dimensions. Hello again and thank you to anyone who has read my thoughts as posts on my linked in profile. 😉 First the universe is roughly astronomical in size, biology is astronomical in figures, and the quantum dimension under that, astronomical in figures. What I am trying to say here is, we instinctively think of the astronomical universe as vast and massive, numerological in figurative values, this is a natural instinct, but my point is the other two dimensions biological and quantum, are equally as large, figuratively, the containment of biological materials, to enable the multi dimensionality of biology, with37 billion, trillion reactions taking place in a human body every second, that is one human alone, there are around 9trillion of us, plus other organisms, very astronomical in values. Then last the quantum dimension, under the biological dimensions containment, building. Up biology in fact, in a time, reaction interaction, or Biocosmology, as I call it the study of biological and quantum fields within a space time time critical interactions, beyond genetics, opening life sciences up, for a more open field of study. We need to break the genetic patent barrier patent, to free up life sciences to more people, openly, a time, interaction and outcome within, a timescale. Making it micro-bio-cosmology. Free the fields of the science and hopefully make new breakthrough’s. In short what I am saying is that all three levels, are the same level of enormity of figurative values. I classify biology as a dimension due to higher levels of perfect order by the second or less, it builds up for higher levels of deeper, interactive as they are, into a higher more chemically reproducing, forms r.n.a to d.n.a. Dimensionality, grows deeper in bio chemical and chemical, entropic pathway, higher states of order and so higher dimensionality, eventually to reproduce its self. #dyslexicthinking, #astronomy,#science #quantummechanics

Oppenheim-errrrr makes the case that “dark matter” is not the be-all-end-all answer to all of the other things scientists don’t understand about the universe. A controversial alternate “seed theory” to compete with the dark matter theory is this, in a nutshell: the simulation called “the universe“ is not as bound by time and matter as we think. Perhaps they are just “wobbly.” Dark Matter’s nature has remained mysterious and therefore demands additional honest inquiry, according to the scientific method. Searches by the Large Hadron Collider have come up empty-handed in the quest for dark matter explanation and proof. Last year, the European Space Agency launched a mission, Euclid, aiming to produce a cosmic map of dark matter. The search goes on, as it should. The simpler explanation being proposed in Oppenheim’s “postquantum theory of classical gravity” aims to unite the two pillars of modern physics: quantum theory and Einstein’s general relativity, which are otherwise inexplicably considered fundamentally incompatible. “Oppenheim’s theory envisages the fabric of space-time as smooth and continuous (classical), but inherently wobbly. The rate at which time flows would randomly fluctuate, like a burbling stream, space would be haphazardly warped and time would diverge in different patches of the universe. The theory also envisions an intrinsic breakdown in predictability.” If the construct of “time” has its genesis in the same place as “matter,” then the design certainly could be as “wobbly” as it needs to be to fulfill the purposes of the simulation. Fascinating. Will we ever know? So many things are taught as “follow the science“ when the science is still quite unclear. Maybe we should be taught to only follow the science — once it’s actually proven, and we are told clearly when it has not yet been proven? That would be Science. Oh well, all in good fun. 👽

A new experiment by a collaboration led by the University of Chicago and Fermilab, known as the Broadband Reflector Experiment for Axion Detection or BREAD experiment, has released its first results in searching for dark matter. One of the great mysteries of modern science is searching for dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. It’s no minor thing—currently, scientists think it makes up about 85% of all the mass in the Universe. #DarkMatter #ParticlePhysics #BREADExperiment #Universe Click the link below to discover more ⬇ https://bit.ly/3U4vnM4

This discovery, made in September 1846, became one of the most sensational discoveries of astronomy. The discovery also became one of the greatest triumphs of Newton's theory of gravity. Based on Newton's law of gravitation, Alexis Bouvard charted the path of Uranus in a table published in 1821. Uranus was discovered in 1781 and completed its first revolution in 1845. The observations suggested that Uranus deviated from the path it should have followed as predicted by Bouvard. Based on the anomaly, Bouvard postulated that some unknown body was responsible for this perturbation. John Couch Adams, while still an undergraduate, wanted to explore the perturbation seriously. Adams started doing his mathematics with the intention to determine the mass, position, and the orbit of the body causing the perturbation. Urbain Le Verrier in France made similar predictions about this unknown body using the tools of mathematics. British Astronomer Royal George Airey convinced astronomer James Challis to search for the planet that was causing this deviation within Uranus' orbit. James Challis searched the skies to look for this hidden giant throughout August and September. However, he looked at the right time but in the wrong place. If James Challis had looked for this planet in the region predicted by John Couch Adams, he would have made one of the greatest discoveries of astronomy: the first planet discovered solely on the basis of mathematical calculations. Meanwhile Urbain Le Verrier sent his results to the Berlin observatory. In Berlin, the astronomers had no idea that they were going to immortalize their observatory after discovering the eighth planet of the solar system. On September 23-24, 1846, Johan Gottfried Galle used the Fraunhofer telescope at the Berlin observatory and found the new member of the solar system. The planet was only 1 degree from its calculated position. Neptune became the first planet which was predicted mathematically before it's direct observation. The discovery of Neptune became one of the greatest testimonies to the fact that mathematics is indeed the mother tongue of nature. Do you know that a similar planet was predicted to affect the orbit of Mercury? This had an interesting connection with Einstein's General Relativity. Share your answer in the comment section.
