1) Tycho Brahe made careful observations of astronomical events which helped Kepler discover his laws of planetary motion. Kepler found that planets orbit the sun in ellipses, with the sun at one focus, and that they sweep out equal areas in equal times.
2) Newton used Kepler's laws and mathematics to show that planetary orbits must be governed by an inverse-square law of gravitational attraction between the planet and sun.
3) Newton proposed his law of universal gravitation, which states that every particle in the universe attracts every other particle with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
The solar system is made up of the Sun, the planets that orbit the Sun, their satellites, dwarf planets and many, many small objects, like asteroids and comets. All of these objects move and we can see these movements. We notice the Sun rises in the eastern sky in the morning and sets in the western sky in the evening. We observe different stars in the sky at different times of the year.

Nuclear Gravitation Field Theory Demonstrates Strong Nuclear Force is GravityKen Wright
Â
Nuclear Gravitation Field Theory (NGFT) evaluates Strong Nuclear Force with respect to Newton's Law of Gravity, and General Relativity. NGFT demonstrates that when enough nucleons are present in the nucleus to classically form a near perfect spherical shape, the proton and neutron energy levels fill in the same way the electron energy levels fill indicating the potential function is proportional to 1/r^2. NGFT demonstrates the intensity of the Nuclear Gravitation Field is stronger than the Nuclear Electric Field in order to hold the protons and neutrons together in the Nucleus. The Nuclear Gravitation Field at the surface of the Nucleus rivals that of a Neutron Star or Black Hole, therefore, it drops like a rock just outside the Nuclear surface due to Space-Time Compression. The Nuclear Gravitation Field then propagates outward with the feeble intensity we see as gravity.
The update demonstrates the apparent "saturation" of the Strong Nuclear Force occurs because of Space-Time Compression occurring within the Nucleus. This effect can only occur if the Strong Nuclear Force is Gravity.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
Â
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
Â
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Â
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.
2. Motion in the Heavens and on Earth We know how objects move on Earth. We can describe and even calculate projectile motion. Early humans could not do that, but they did notice that the motions of stars were quite different. Stars moved in regular paths. Planets moved in more complicated paths. Because of Kepler, Newton and others, we now know that these objects follow the same laws that govern the motion of golf balls and other objects here on Earth.
4. Tycho Brahe, at the age of 14, observed an eclipse of the sun on August 21, 1560. The date of the event was off by two days as predicted in all of the books of the time, so Brahe decided to become an astronomer to make accurate observations and predictions.
5. In 1597, after falling out of favor with his sponsor, Brahe moved to Prague. There, he became the astronomer to the court of Emperor Rudolph of Bohemia. Johannes Kepler became one of his assistants.
7. Brahe strongly believed that Earth was the center of the universe, Kepler, however, wanted to use a sun-centered system to explain Braheâs precise data.
8. He [Kepler] was convinced that geometry and mathematics could be used to explain the number, distance, and motion of the planets. Kepler discovered three mathematical laws that describe the behavior of every planet and satellite.
10. 1. The paths of the planets are ellipses with the sun at one focus.
11. 2. An imaginary line from the sun to a planet sweeps out equal areas in equal time intervals. Thus, planets move faster when they are closer to the sun and slower when they are farther away from the sun.
14. 3. The square of the ratio of the periods of any two planets revolving about the sun is equal to the cube of the ratio of their average distances from the sun.
18. Note that the first two laws apply to each planet, moon, or satellite individually. The third law, however, relates the motion of several satellites about a single body.
19. Universal Gravitation In 1666, some 45 years after Kepler did his work, 24-year-old Isaac Newton used mathematics to show that if the path of a planet were an ellipse, which was in agreement with Keplerâs first law of planetary motion, then the magnitude of the force, F , on the planet must vary inversely with the square of the distance between the center of the planet and the center of the sun.
21. The symbol ïĄ means is proportional to , and r is the distance between the centers of the two bodies. ï
22. Newton also showed that the force acted in the direction of the line connecting the centers of the two bodies . But was the force that acted between the planet and the sun the same force that caused objects to fall to Earth?
24. Newton wrote that the sight of a falling apple made him think about the problem of the motion of the planets. He recognized that the apple fell straight down because Earth attracted it .
25. He wondered whether this force might extend beyond the trees to the clouds, to the moon, and even beyond. Could gravity be the force that also attracts the planets to the sun?
26. Newton hypothesized that the force on the apple must be proportional to its mass. Thus, the force of attraction also must be proportional to the mass of Earth.
27. This attractive force that exists between all objects is known as gravitational force.
28. Newton was so confident that the laws governing motion on Earth would work anywhere in the universe that he assumed that the same force of attraction would act between any two masses, m A and m B .
29. He proposed his law of universal gravitation, which is represented by the following equation. In the equation, r is the distance between the centers of the masses, and G is a universal constant - it is the same everywhere.
30. According to Newtonâs equation, if the mass of a planet near the sun were doubled, the force of attraction would be doubled. Similarly, if the planet were near a star having twice the mass of the sun, the force between the two bodies would be twice as great.
32. If the planet were twice the distance from the sun, the gravitational force would be only one quarter as strong. Because the force depends on 1/ r 2 , it is called the inverse square law .
34. Motion of Planets and Satellites Newton used a drawing similar to the one shown in Figure 8-6 to illustrate a thought experiment on the motion of satellites. Imagine a cannon, perched high atop a mountain, firing a cannonball horizontally with a given horizontal speed. The cannonball is a projectile, and its motion has both vertical and horizontal components. Like all projectiles on Earth, it follows a parabolic trajectory. During its first second of flight, the ball falls 4.9 m. If its horizontal speed were increased, it would travel farther across the surface of the earth, but it would still fall 4.9 m in the first second of flight.
35. This means that, after the first second, the cannonball is at the same height as it was initially. The curvature of the projectile will continue to just match the curvature of Earth, so that the cannonball never gets any closer or farther away from Earthâs curved surface. When this happens, the ball is said to be in orbit. Newtonâs drawing shows that Earth curves away from a line tangent to its surface at a rate of 4.9 m for every 8 km. An object at Earthâs surface with a horizontal speed of 8 km/s will keep the same altitude and circle Earth as an artificial satellite.
37. A satellite in an orbit that is always the same height above Earth moves with uniform circular motion. Recall from Chapter 7 that its centripetal acceleration is given by a c = v 2 /r. Newtonâs second law, F = ma, can be rewritten as F = mv 2 /r. Combining this with Newtonâs inverse square law (remember that?) produces the following equation. Gm E m r 2 ïœ mv 2 r
38. Solving this for the speed of an object in circular orbit, v , yields the following By using Newtonâs law of universal gravitation, you saw that the time, T , for a satellite to circle Earth is given by the following. Note that both the orbital speed, v , and period, T , are independent of the mass of the satellite. Neat-o animation. v = Gm E r T = 2Ï r 3 Gm E
39. These equations for the speed and period of a satellite can be used for any body in orbit about another.
40. The acceleration of objects due to Earthâs gravitation can be found by using Newtonâs law of universal gravitation and second law of motion.
42. On Earthâs surface, d=r E and the following equation can be written. g = Gm E /r E 2 Thus, a = g(r E /d) 2
43. As you move farther from Earthâs center, that is, as d becomes larger, the acceleration due to gravity is reduced according to the inverse square law.
44. âWeightlessnessâ or âzero-gâ is caused by this fact. There is no âweightlessnessâ however. Gravity still exists and is pressing down on people.
