Nicolaus Copernicus (1473-1543) was a Polish astronomer who proposed a model of the solar system in which the Sun is at the center and the Earth and planets orbit around it. This contradicted the prevailing Ptolemaic system where Earth was the center. Copernicus published his theory, called the Copernican or heliocentric system, in 1543 in his book On the Revolutions of the Celestial Spheres. Although not widely accepted in his lifetime, Copernicus' model eventually replaced the Ptolemaic system as the accepted astronomical model.
The geocentric theory stated that the earth was the center of the universe and was the most accepted viewpoint for a long, long time. The heliocentric theory, on the other hand, states that the earth revolves around the Sun. The first advocate of a heliocentric model was Aristarchus of Samos in ancient Greece.
Nicolaus Copernicus set off a scientific revolution with his Sun-centered view of the Universe.

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of pre-history: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World (see astrology and astronomy). In some cultures, astronomical data was used for astrological prognostication.
Ancient astronomers were able to differentiate between stars and planets, as stars remain relatively fixed over the centuries while planets will move an appreciable amount during a comparatively short time.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

4. Nicolaus Copernicus Known for : Proposing a heliocentric (sun-centered) model (1500s) for the solar system, in which the Sun is stationary at the center, and Earth and the other planets orbit around it. Copernican System theory of planet movements: the theory of Nicolaus Copernicus regarding the mechanics of the solar system, which postulates that the Earth and other planets revolve around the Sun. This theory challenged the Ptolemaic system of astronomy that had prevailed since the 2nd century.
6. Nicolaus Copernicus Heliocentric plan of the Solar System in the first edition of Copernicus’ De Revolutionibus 1. Sun 2. Mercury 3. Venus 4. Earth 5. Mars 6. Jupiter 7. Saturn 8. Celestial sphere
7. Nicolaus Copernicus Career: 1491-1494: Studied mathematics at Kraków Academy (now Jagiellonian University) 1496: Went to Italy to study astronomy and law at the University of Bologna 1497: Began observations of the Sun, Moon, and planets 1514?: Wrote Commentariolus, an outline of his astronomical ideas, but did not circulate it widely 1543: Published De Revolutionibus Orbium Coelestium (On the Revolutions of the Celestial Spheres), which held that Earth and the other planets orbit a centrally located Sun.
9. Nicolaus Copernicus Did You Know: Before Copernican theory was accepted, astronomers believed that Earth was stationary at the center of the solar system, and the Sun and planets revolved around it. Copernicus was best known to his contemporaries as a doctor and the Canon of Frauenburg Cathedral. Italian physicist and astronomer Galileo attempted to publicize Copernican theory in the early 1600s, and was convicted of heresy as a result. Copernican theory was not widely accepted until the late 17th century—over 100 years after Copernicus's death. Copernicus's book, De Revolutionibus Orbium Coelestium, was banned as heretical by the Catholic Church until 1835.
10. Nicolaus Copernicus Planetary Motions According to Copernicus A person moving at uniform speed is not necessarily aware of his motion. Copernicus argued that the apparent annual motion of the Sun about the Earth could be represented equally well by a motion of the Earth about the Sun. The apparent rotation of the celestial sphere could also be accounted for by assuming that the Earth rotates about a fix axis while the celestial sphere is stationary.
11. Nicolaus Copernicus Planetary Motions According to Copernicus He deduced that the nearer a planet is to the Sun, the greater is its orbital speed. The retrograde motions of the planets were easily understood without the necessity for epicycles. He worked out the correct approximate scale of the Solar System. He resorted to using a number of epicycles in order to achieve the accuracy he required in predicting the positions of the planets in the sky. He maintained the concept of uniform circular motion in his theory.
12. Nicolaus Copernicus Planetary Motions According to Copernicus The heliocentric model did not prove that the Earth revolves around the Sun. Ptolemaic model was clumsy, it lack the beauty and symmetry of the Copernican model. In the Copernican model the Earth seems to be no longer the central element of the universe.
13. Nicolaus Copernicus The Scale of the Solar System Definition of Terms 1. Superior Planet Any planet whose orbit is larger than that of the Earth. 2. Inferior Planet A planet closer to the Sun than the Earth is. 3. Elongation The angle formed at the Earth between the Earth-planet direction and the Earth-Sun direction.
14. Nicolaus Copernicus The Scale of the Solar System Definition of Terms (Continued) 4. Opposition Configuration of the planet when its elongation is 180 degrees. 5. Conjunction The configuration of a planet when it has the same celestial longitude as the Sun, or the configuration when any two celestial bodies have the same celestial longitude or ascension. 6. Quadrature A superior planet is at quadrature when a line from the Earth to the Sun makes a right angle with the line from the Earth to the planet.
17. Nicolaus Copernicus The Scale of the Solar System When an inferior planet is at greatest elongation: EP - must be tangent to the orbit of the planet. - hence perpendicular to the line from the planet to the Sun (PS). We therefore have a right triangle (EPS). Greatest elongation is at PES. ES – will be Earth’s distance from the Sun. PS – distance of the planet to the Sun, can then be found in terms of the Earth’s distance, by geometrical construction or by having trigonometric calculation.
19. Nicolaus Copernicus The Scale of the Solar System Suppose planet P is at opposition. We can now time the interval until the planet is next at quadrature. Quadrature happens when: The planet is at P’ and the Earth is at E’. With a knowledge of the revolution periods of the planet and the Earth, we can calculate the fractions of their respective orbits that have been traversed by the two bodies. Thus the angles PSP’ and ESE’ can be determined.
20. Nicolaus Copernicus The Scale of the Solar System Subtracting PSP’ and ESE’ gives the angle P’SE’. SE’ is the Earth’s distance from the Sun. Enough data are then available to solve the triangle and find the distance for P’S by geometric construction or calculation.
23. Nicolaus Copernicus Sidereal and Synodic Period Copernicus recognized the distinction between the sidereal period and the synodic period. Sidereal period is simply the period of revolution of a planet about the Sun. Synodic period is the time required for it to return to the same configuration, such as the time from opposition to opposition or conjunction to conjunction. What is observed directly from the planet is the synodic period.
