This document discusses views about the Earth and universe throughout history. It addresses debates around whether Earth is the center of the universe and whether ancient people knew the Earth was round, not flat. The document also summarizes early models of the solar system including geocentric models with Earth at the center proposed by Aristotle and Ptolemy, and the heliocentric model proposed by Copernicus with the sun at the center. Key figures who contributed to the shifting model of the solar system from geocentric to heliocentric are also mentioned, including Copernicus, Tycho Brahe, and Johannes Kepler.

physical science senior high school Q2 WEEK 1.pptx
1) Ancient civilizations believed the Earth was flat until the Greeks proposed it was spherical based on observations of lunar eclipses and the circular shadows cast on the Moon.
2) Early models of the universe placed Earth at the center, with Copernicus and others later advocating heliocentric models with the Sun at the center.
3) Galileo's observations with early telescopes, such as the moons of Jupiter and sunspots, provided evidence supporting heliocentric models and advancing astronomical understanding.
Physical science chapter1 for shs
The Greek's viewed the universe as having celestial and terrestrial motion, with objects moving in perfect circular orbits around a spherical Earth at the center. Models of the universe differed on the orbital center - either Earth, Sun, or concentric spheres. Kepler's Laws showed planetary orbits are elliptical with the Sun at one focus, areas are swept equal in equal time, and orbital periods increase with orbital radius.
WEEK 1 MODEL OF THE UNIVERSE.pptx
The document discusses the celestial sphere and coordinate system used in astronomy. It identifies key points on the celestial sphere including the north and south celestial poles, declination, right ascension, the ecliptic, and the vernal equinox. It then discusses the contributions of various ancient Greek astronomers such as Aristarchus, Hipparchus, Ptolemy, Copernicus, Brahe, and Kepler. Key contributions included Aristarchus proposing the heliocentric model of the universe, Hipparchus' astronomical observations and measurements, Ptolemy developing the geocentric Ptolemaic system, Copernicus also proposing the heliocentric model, Brahe's precise observations, and Kepler's formulation of the three laws of planetary

Ptolomy, copernicus, and kepler's laws
Early models of the solar system described the Earth as stationary at the center with celestial objects revolving around it in circular orbits. Ptolemy developed an influential geocentric model that explained observations using epicycles but was inaccurate. Copernicus proposed a heliocentric model placing the Sun at the center. Kepler analyzed Brahe's precise observations of Mars to deduce its elliptical orbit and formulated his three laws of planetary motion, establishing the foundations of modern astronomy.
Introduction to cosmology
1) The document discusses ancient Greek and early modern scientific models of cosmology and the solar system. It describes models proposed by thinkers like Aristotle, Ptolemy, Copernicus, Brahe, Galileo and Kepler.
2) Key events included Galileo's observations of Jupiter's moons and Venus' phases, which supported Copernicus' heliocentric model over the Ptolemaic geocentric one. Brahe made accurate observations without telescopes that challenged Aristotelian ideas.
3) Kepler developed his laws of planetary motion based on Brahe's observations, establishing elliptical orbits with the Sun at one focus and relationships between orbital periods and distances. This provided strong evidence for the Copernican model of a Sun-
Greek astronomy
This document provides an overview of early Greek astronomy from Plato to Ptolemy. It discusses how Plato and Aristotle viewed the universe, with Plato believing in uniform circular motion and Aristotle recognizing lunar phases and arguing that the moon reflects sunlight. It then covers how later Greek astronomers like Hipparchus made important advances, including developing star catalogs and discovering precession. The document concludes with Claudius Ptolemy, who synthesized the knowledge in his influential book "The Almagest," establishing the geocentric Ptolemaic system as the standard model for over 15 centuries.
The History of Astronomy
The document traces the development of scientific understanding of the solar system from ancient times to the modern era. It describes early geocentric models proposed by Anaximander and Ptolemy that placed Earth at the center. Later thinkers such as Aristarchus, Copernicus, and Galileo proposed heliocentric models with the Sun at the center. Kepler determined orbits were elliptical rather than circular, and Newton explained planetary motion through universal gravity. Edwin Hubble's discovery of an expanding universe led to the development of the Big Bang theory.

The theory was eventually replaced by the heliocentric model of Copernicus, Galileo and Kepler, which placed the Sun at the center.
Early Observers Astronomers ppt jshay v1.ppt
Ancient cultures studied the sky and developed early calendars and astronomy by observing cyclic patterns of celestial objects like the sun, moon, and stars. They used structures like Stonehenge and sites in Egypt to track solstices and help form early understandings of days, months and years. Over millennia, models evolved from geocentric views to the eventual heliocentric model established by Copernicus, Kepler, Galileo and Newton, through precise observations, mathematical laws, and the discovery of gravity.

3rd Universe Model .pptx
The document discusses models of the early universe proposed by ancient Greeks. It describes both geocentric models which placed Earth at the center, including those of Pythagoras, Plato, Aristotle, and Ptolemy involving celestial spheres, and heliocentric models like Aristarchus' which placed the Sun at the center. The models attempted to explain observations of planetary motions and positions of celestial objects in the sky through the early Greeks' philosophical and religious perspectives before the invention of advanced astronomical tools.

Ancient cultures studied the sky and developed calendars based on observed cycles of celestial objects like the sun, moon, and stars. They noticed that the sun rises and sets daily, the moon's appearance changes monthly in a repeating cycle of phases, and stars return to the same positions annually. Over millennia, observations led to models of the universe, from geocentric ones placing Earth at the center, to the eventual acceptance of Copernicus' heliocentric model with the sun at the center.
HOW GREEKS KNEW EARTH IS SPHERICAL1.1.pptx
The Greeks knew the Earth was spherical through several lines of evidence:
- Pythagoras first proposed a spherical Earth around 500 BC.
- Anaxagoras observed circular shadows on the Moon during lunar eclipses, indicating the Earth was round.
- Aristotle made detailed arguments including that the North Star appears higher in the sky the farther north you travel, and ships disappear over the horizon progressively from bottom to top.
- Eratosthenes calculated the circumference of Earth by measuring the sun's angle at different locations, arriving at a value close to modern measurements.
Models-of-the-Universe.pptx
Here are two potential responses in 2-3 sentences each:
1. I would show my flat-earther friend that no matter which way I point the Frisbee, it will always cast a circular shadow on the ball, demonstrating that only a spherical object can do this. Eratosthenes proved the Earth was round using a similar shadow experiment over 2000 years ago.
2. Tycho Brahe spent over 20 years meticulously recording the positions of planets with unprecedented accuracy. This treasure trove of observational data was invaluable for Kepler to analyze and discover the elliptical orbits of planets, replacing the imperfect circular/epicyclic models. Without Brahe's precise records, Kepler would not have been able to derive his revolutionary laws of planetary
astronomy1.ppt
The document discusses the history of astronomy from ancient to modern times. It begins by explaining how early civilizations used the movement of stars, planets and the moon to tell time before modern clocks. It then discusses key figures like Ptolemy who proposed an Earth-centered model, Copernicus who proposed a Sun-centered model, Galileo who used a telescope to observe moons orbiting Jupiter which supported Copernicus, and Kepler who formulated laws of planetary motion. The document also discusses constellations, stars, and life cycles of stars of different masses.
The planet earth
Earth is a planet that formed around 4.6 billion years ago from a cloud of gas and dust. It is the only planet known to support life. Earth is spherical in shape but slightly oblate, meaning it bulges at the equator. It rotates on its axis once every 24 hours and revolves around the sun once every 365 days. Earth has four major interior layers - crust, mantle, outer core, and inner core. NASA studies Earth using satellites to monitor changes to its land, oceans, atmosphere, and climate in order to better understand and predict environmental changes.
PPT Models of the Universe.ppt
The document discusses models of the universe throughout history. It describes the geocentric model proposed by Aristotle and Ptolemy, in which the Earth is at the center. Nicolaus Copernicus proposed a heliocentric model, with the Sun at the center. Galileo Galilei used the telescope to observe evidence supporting Copernicus' model, such as the phases of Venus and moons orbiting Jupiter. Johannes Kepler mathematically modeled the planets' elliptical orbits around the Sun. Modern science continues to refine models of the universe as new evidence is discovered.

99 years modern astronomy
This document discusses the progression of ideas in astronomy from ancient Greek thinkers to Isaac Newton. It describes the models proposed by Claudius Ptolemy, Nicolaus Copernicus, Tycho Brahe, Johannes Kepler, and Galileo Galilei. Kepler discovered the elliptical orbits of planets and his three laws of planetary motion. Newton then proposed his law of universal gravitation to explain what causes planets to remain in orbit. By the late 1600s, it had been established that the Sun is at the center of the solar system and that planets move according to the principles of inertia and gravitation.
Astronomy by victor r
Ancient cultures like the Chinese, Egyptians, and Babylonians began recording the motions of celestial objects like the sun, moon, and planets over 5,000 years ago to track seasons and plan activities. The Golden Age of astronomy from 600 BC to AD 150 centered in Greece, where scientists like Aristotle and Eratosthenes made early attempts to measure the size and distances of astronomical bodies using geometry and trigonometry. Later, Copernicus, Kepler, Galileo and Newton developed the heliocentric model of the solar system and laws of planetary motion through observations and mathematical analysis, overturning the geocentric Ptolemaic model that had dominated for over 1,000 years. Their work established modern astronomy and understanding of

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
