The document discusses the huge waves seen on the water planet near the black hole Gargantua in the film Interstellar. It explains that the massive gravitational pull of Gargantua, being over 100 million times more massive than the sun, causes intense tidal forces that generate seismic activity and gigantic waves over 1 kilometer high on the planet's surface, in a similar way that the moon's gravity causes Earth's tides. While Gargantua itself is fictional, the science behind its tidal effects on the water planet are based on real physics involving black hole tidal forces.

Tides are caused by the gravitational pull of the Moon and, to a lesser extent, the Sun. The Moon's gravity creates bulges in the Earth's oceans that result in high and low tides about every six hours. There are two types of tides: spring tides, which occur during a full moon or new moon and have the largest difference between high and low tides, and neap tides, which occur when the Sun and Moon are at right angles to each other and have a smaller difference between tides.
Let`S Talk About The Earths Tides
This document discusses the tides and how they are influenced by the moon's phases. It begins with an introductory activity to refresh knowledge of moon phases. It then explains that tides are caused by the gravitational pull of the moon and sun, which causes bulges in the oceans. Spring tides occur during full moons and new moons when gravitational forces are strongest. Neap tides occur during quarter moons and have weaker tides. The document includes diagrams and activities to illustrate these concepts. It concludes with assigning students into groups to create posters about different moon phases and their effect on tides.
The moon and tides
The document discusses various lunar phenomena such as micro moons, blue moons, blood moons, eclipses, and tides. A micro moon occurs when the full moon coincides with the moon's farthest point from Earth. There are three types of lunar eclipses defined as penumbral, partial, and total. Eclipses happen when the sun, moon, and Earth are aligned. Tides are influenced by the gravitational pull of the moon and sun, and there are two types of tides called spring tides and neap tides.
The Moon and Tides - Spring vs. Neap Tides
Spring tides occur during new and full moons when the sun and moon are aligned, causing their tidal bulges to constructively interfere and produce the largest difference between high and low tides. Neap tides happen at quarter moons when the sun and moon are at right angles, causing their tidal bulges to destructively interfere and result in a smaller tidal range. The tidal range is greatest when the moon is closest to Earth at perigee and Earth is closest to the sun at perihelion.

How Universe & Life formed
The document summarizes the evolution of the universe, from the initial uneven distribution of particles to the current state of celestial bodies orbiting and attracting each other due to gravity. It describes how planets have moved closer to stars and larger planets have increased their gravitational pull over time. It also outlines key events in the evolution of Earth, including how collisions with meteors shaped its surface and atmosphere, and how the collision with the moon caused Earth to shift closer to the sun. The document concludes by noting the collision of a meteor led to the destruction of dinosaurs and the rise of human civilization on Earth.
Seasons phases eclipses and tides
- Earth rotates on its axis once every 24 hours, causing day and night. It revolves around the sun once every year (its orbit).
- The tilt of the Earth on its axis causes the seasons. Summer occurs when the location is tilted toward the sun, and winter occurs when it is tilted away.
- The moon orbits the Earth, causing phases like the waxing and waning crescent, gibbous, full and quarter moons. Eclipses occur when the moon passes between the Earth and sun (solar eclipse) or Earth passes between moon and sun (lunar eclipse).
Our marvelous moon2

Retrogression of planets
The document discusses the retrogression of planets as seen from Earth and the Sun. Planets can appear to move backwards (retrograde) due to the different motions of Earth and other planets around the Sun. The inner planets Mercury and Venus may seem to weaken when retrograde as they are closer to Earth, while the outer planets like Mars, Jupiter and Saturn may seem stronger when retrograde since Earth is positioned between them and the Sun. The apparent retrograde motion and effects on planetary strength are explained by Newton's law of universal gravitation.
Our marvelous moon1
The document discusses the moon's formation, physical features, the lunar cycle, ocean tides, and eclipses. It examines theories about how the moon formed, including the fission, capture, and giant impact theories. It describes the moon's repeating 29.5 day cycle between its phases from new to full moon. It also explains how the moon's gravity causes high and low ocean tides on Earth through bulges in the seas.
Tide notes part 2
Tides are caused by the combined gravitational forces of the sun and moon on Earth's oceans. There are two types of tides: spring tides that occur during a new or full moon when the sun and moon are aligned, producing the highest high tides and lowest low tides; and neap tides that happen during a first quarter or third quarter moon when the sun and moon are at a right angle, resulting in smaller tidal ranges with higher low tides and lower high tides than normal.
6 -earth_s_motions
Earth rotates on its axis over 24 hours, causing day and night. It also revolves around the Sun over 365 days, causing seasons. The tilt of Earth's axis remains the same, directing more solar radiation at the Northern hemisphere in summer and Southern hemisphere in winter. The seasons are caused by the combined effects of Earth's elliptical revolution, tilt, and rotation on its axis.
Eclipses
The document discusses eclipses and lunar phases. It begins by providing background information on the moon's orbit and how it reflects sunlight before explaining the different lunar phases. It then describes the causes of lunar phases and provides diagrams. The document also discusses the different types of solar and lunar eclipses, providing examples and upcoming dates. It concludes by briefly explaining the causes of ocean tides due to the moon and sun's gravity.
Earth moon sun
The document discusses relationships between Earth, the Moon, and the Sun. It explains that rotation is the turning of a body on its axis, such as Earth rotating daily, while revolution is the motion of one body around another, such as Earth revolving around the Sun yearly. It also defines insolation as the amount of solar radiation reaching Earth and describes how the tilt of Earth's axis and its revolution cause seasons by changing the Sun's angle of incidence across the globe throughout the year.
Our marvelous moon1
The document summarizes key facts about the moon's formation, physical features, lunar cycle, effect on ocean tides, and eclipses. Regarding formation, it discusses the fission, capture, and giant impact theories. It notes the moon's diameter is 1/4 of Earth's, with surface area less than 0.1% of Earth. The lunar cycle repeats every 29.5 days between waxing and waning phases. Ocean tides are caused by the moon's gravitational pull creating two bulges. During a solar eclipse the moon is between Earth and the sun, and in a lunar eclipse Earth is between the moon and sun.
12.1 earth, moon, sun
Early civilizations closely observed the sky and used celestial movements to track time and guide activities. It was later discovered that the Earth revolves around the Sun, while the Moon revolves around Earth. The Moon was formed from debris ejected after a giant impact between Earth and another planet. Its phases and gravitational pull are responsible for ocean tides and it has no atmosphere or erosion, leaving ancient craters visible.
effects of r
The document discusses the effects of the Earth's revolution around the sun, including variations in day and night lengths, heat distribution across the Earth, and the occurrence of seasons. It explains that the Earth's tilted axis and revolution cause different parts of the planet to receive different amounts of sunlight throughout the year, resulting in longer days than nights in summer and vice versa in winter. It also describes how the sun's rays are more vertical and intense near the equator, becoming more slanted and less intense farther from the equator. Finally, it notes that the Earth's seasons are caused by its tilted axis, not differences in its distance from the sun, with different parts oriented toward the sun over the course of the year.
Earth moon sun notes
The document summarizes key concepts about the Earth-Moon-Sun system. It describes the Earth's rotation, revolution around the Sun, and axial tilt, which cause day/night and seasons. It discusses the Moon's orbit and phases as it revolves around Earth. Eclipses occur when the Moon passes between Earth and Sun. The Moon causes tidal bulges on Earth related to its gravity, producing ocean tides.
Ufo's and no_sonic_boom
The document discusses the possibility that particle collisions in the Large Hadron Collider could produce tiny localized gravity effects. It suggests that within the area of such a collision, some particles could experience a force similar to gravity due to energy turbulence. However, this would not result in a net gravitational pull outside of the collision area. As an analogy, it compares this to how a paddle creates small whirlpools that pull on nearby water but do not change the overall water level. It further speculates that such localized gravity fields could enable new forms of propulsion for spacecraft by reducing g-forces during acceleration and allowing easier interstellar travel.
rotation and revolution
The document discusses different types of rotational and orbital motions of objects in space, including the Earth. It explains that the Earth's rotation on its axis causes day and night, while its revolution around the sun over the course of a year leads to seasonal variations due to changes in the sun's angle and day length. Examples of rotation are a top spinning on its axis or the Earth each day, while examples of revolution are the Earth orbiting the sun each year or the moon revolving around the Earth.
Rotation and revolution
The Earth rotates on its axis from West to East, causing day and night. It also revolves around the Sun, causing seasons. The Equator divides the Earth into the Northern and Southern Hemispheres. Rotation and revolution are responsible for different weather patterns and climates in different places over time. Sea breezes occur during the day as warmer air rises over heated land, drawing in cooler air from the sea.
Moon g6 1
The moon has many impact craters formed by collisions with space objects. It also has large, flat dark areas called maria that were formed by volcanic lava filling huge craters. There are also mountainous regions near the edges of maria and older, more heavily cratered highlands near the lunar poles. The changing phases of the moon are caused by the different portions of the moon that are illuminated by the sun as it orbits Earth. Eclipses occur when the moon passes through Earth's shadow (lunar eclipse) or the moon passes between Earth and the sun blocking the sun's light (solar eclipse). The gravitational pull of the moon is responsible for Earth's ocean tides.
Earth's Rotation
The document discusses several key facts about Earth's rotation:
- Earth spins on an imaginary axis, completing one rotation every 24 hours at a speed of over 1,000 mph.
- Earth's rotation causes day and night and influences the number and placement of time zones around the world.
- Earth bulges slightly at the equator due to the centrifugal force of its rotation.
- Earth's tilted axis and yearly orbit around the sun influence the seasons and amount of sunlight different areas receive through the year.
Power point
Tides are caused by the gravitational forces of the Moon and Sun and the rotation of the Earth, rising and falling with approximately 12 hour periods and being influenced by near-shore terrain. Seasons result from the Earth's yearly orbit and axial tilt, causing changes in sunlight intensity that affect animal hibernation and migration and plant dormancy. The Big Bang theory proposes that the universe expanded from an extremely dense and hot state and continues expanding, carrying galaxies with it like raisins in an expanding loaf of bread.
Tides guillermo, héctor and hugo
The document discusses tides, which are the periodic rise and fall of sea levels caused by the gravitational attraction of the moon and sun. It explains that Isaac Newton realized tides were caused by these gravitational forces. There are two types of tides - low tides when sea levels are lowest, and spring tides caused by perfect alignment of the sun, moon, and earth. The document also mentions that tidal energy harnesses the energy of tides and has potential as a clean, renewable energy source.
Chapter 3 rotation and revolution
The document discusses the rotation and revolution of the Earth. It explains that rotation is the spinning of the Earth on its axis, which causes day and night, while revolution is the movement of the Earth around the Sun, taking one year to complete. It also describes how the tilt of the Earth's axis and its revolution cause the four seasons in the northern and southern hemispheres.
Colton's Rotation and Revolution Powerpoint
The document discusses how the Earth orbits the sun through revolution, which causes seasons due to the concentration of sunlight over different hemispheres throughout the year. It also explains how the Earth rotates on its axis, leading to day and night as different parts of the planet face the sun during its daily spin. The tilt of the Earth's axis further influences the seasons by affecting sunlight distribution across the hemispheres.
Moon g6 2
The document summarizes key features of the lunar landscape as observed from Earth. It describes light and dark colored areas on the moon's surface, including craters formed by impacts, large flat dark areas called maria formed by ancient lava flows, mountains around the edges of maria, and older highlands near the lunar poles with more craters. It also discusses lunar phases caused by the changing orientation of the moon as it orbits Earth, solar and lunar eclipses, and tides caused by the gravitational pull of the moon and sun.
Tides & tidal waves
In this presentation, one will find more elaborative and detailed information on the topic of TIDES with full depth knowledge about its various aspects including the forces that act on it, how & when they act on it with illustrative images.
tides.pptx
The Moon's gravitational pull is the primary cause of tides on Earth. The Moon creates bulges in the Earth's oceans on the side facing it and on the opposite side due to having a stronger gravitational attraction being closer. As the Earth rotates, different places experience high and low tides as they come into alignment with these bulges. The Sun also influences tides through its gravitational pull, sometimes reinforcing and other times counteracting the Moon's effects. Spring tides occur during full and new moons when the Sun and Moon are aligned to produce higher tides, while neap tides have lower heights and occur during half moons when their pulls are at right angles.

Tides (Coyle)
Tides are caused by the gravitational pull of the moon and sun on the Earth's oceans. This creates bulges of water on opposite sides of the Earth that result in regular rises and falls of sea level called tides. The moon has a stronger influence than the sun due to its closer proximity. Tides are strongest in coastal areas and weakest in the open ocean. There are typically two high tides and two low tides each day, known as semidiurnal tides, though some locations only experience one of each, called diurnal tides.
Maddy, Hannah and Jillin
Tides are caused by the gravitational pull of the moon and sun. There are two main types of tides: spring tides and neap tides. Spring tides occur when the sun and moon are aligned, creating higher high tides and lower low tides. Neap tides have weaker tidal ranges and occur when the sun and moon are at right angles to each other. The document also includes diagrams and pictures to illustrate high and low tides.

The moon has many geological features formed by impacts, including craters caused by objects hitting the surface and maria, which are large, flat dark areas formed by ancient lava flows. Other features include mountains around the edges of maria, highlands near the lunar poles with more craters, and valleys such as Alpine Valley. The moon also experiences phases as the illuminated side facing Earth waxes and wanes, and eclipses can occur when Earth blocks the sun's light during a lunar eclipse or the moon blocks sunlight during a solar eclipse. Tides on Earth are caused by the gravitational pull of the moon.
Tides
Tides are the periodic rise and fall of ocean water levels caused by the gravitational forces of the moon and sun. The dominant force is the moon, as it is closer to Earth. This causes bulges in the ocean on opposite sides of Earth called high tides, with low tides occurring between them. The periodic rise and fall happens twice each day. Tidal ranges vary depending on the positions of the Earth, moon, and sun, causing spring tides with the largest ranges or neap tides with minimum ranges.
Tides
Tides are the periodic rise and fall of ocean water levels caused by the gravitational forces of the moon and sun. The moon has the strongest effect due to its closer proximity to Earth. This causes bulges in the ocean on opposite sides of Earth called high tides, with low tides occurring between them. The tidal range, or difference between high and low tide, varies depending on the alignment of the sun, Earth, and moon, causing either spring tides with a large range or neap tides with a minimum range.
Sun, Earth, Moon System
This document discusses the relationships between planets, moons, and other celestial bodies. It explains that the Moon orbits the Earth and is considered our natural satellite. A satellite revolves around a planet. Lunar eclipses occur when the Moon passes behind Earth into its shadow, while solar eclipses happen when the Moon passes between Earth and the Sun. The Moon's phases are caused by varying amounts of sunlight reflecting off its surface due to its orbit around Earth. Tides are also influenced by the Moon's gravity, with high and low tides occurring regularly due to the positions of the Moon and Sun relative to Earth.
Life without the Moon
If the Moon suddenly vanished:
- Earth's axis would lose stability and wobble dramatically, causing extreme temperature changes and unpredictable seasons.
- Tides would be much smaller, caused only by the Sun, disrupting marine life and coastal ecosystems.
- Earth's rotation would speed up, with day lengths shortening to 8-10 hours and winds of 160-200 km/h sweeping the surface.
- Life on Earth would struggle to adapt to the entirely different environmental conditions without the stabilizing influence of the Moon.
Earth quake
Earthquakes are caused by the sudden release of built-up strain energy along fault lines in the Earth's crust. Faults occur at boundaries between tectonic plates where the plates slide past each other. There are different types of faults such as normal, reverse, strike-slip and oblique. Earthquake waves called seismic waves radiate out from the hypocenter or focus of the earthquake. P-waves and S-waves are two types of seismic waves that travel through the Earth. Surface waves including Rayleigh and Love waves cause the most damage during an earthquake. Factors like magnitude, distance from the epicenter, local geology can influence earthquake intensity.
Tides
The regular rise and fall of water levels along a shore is caused by tides. Tides are primarily caused by the gravitational pull of the moon on Earth's oceans, which causes the water to bulge on the side facing the moon. Sometimes when the sun, moon, and Earth are aligned, the combined gravitational pull results in especially strong spring tides with higher high tides and lower low tides, while neap tides with weaker gravitational pull result in smaller differences between high and low tides.
The Moon and Tides - What causes tides?
Tides are caused by the gravitational interactions between the Earth, moon, and sun. This causes two tidal bulges in the Earth's oceans, with one bulge facing the moon and the other on the opposite side. As the Earth rotates daily and revolves around its axis, different locations experience high and low tides depending on their alignment with the tidal bulges. Specifically, high tides occur when a location is aligned under the moon or opposite the moon, while low tides occur when a location is at a right angle to the tidal bulges.
Geniushourpowerpoint.pdf
The document discusses tides and provides information about their causes and patterns. Tides are periodic changes in ocean water levels caused by the gravitational pull of the moon and sun. Most places experience two high and two low tides daily (semi-diurnal) but some have only one of each (diurnal). Tides were discovered over 300 years ago by Isaac Newton, who developed the theory that all objects exert gravitational pulls on each other. The document defines and compares spring tides, which occur during full and new moons, and neap tides, which happen during quarter moons and have smaller differences between high and low water levels.
My Genius Hour Project
Tides are periodic changes in the water level of oceans, gulfs and bays caused by the gravitational pull of the moon and sun. Most places experience two high tides and two low tides daily, called semi-diurnal tides, though some have only one per day, called diurnal tides. Tides were discovered over 300 years ago by Isaac Newton, who developed the Equilibrium Theory of Tides to explain how every object exerts a gravitational pull on every other object. There are two main types of tides: spring tides, which occur during full and new moons and have more extreme high and low tides, and neap tides, which happen during half moons and have the
Tides
Tides are the rising and falling of sea levels caused by the combined effects of the gravitational pull of the moon and the sun and the centrifugal force of the Earth's rotation. The moon has the strongest influence due to its closer proximity. This creates bulges in the ocean that result in two high tides and two low tides every 24 hours and 50 minutes. Spring tides occur at new and full moons when the sun, moon, and Earth are aligned, creating higher tides. Neap tides happen when the sun and moon are at right angles, resulting in smaller differences between high and low tides.
The Definition of High Tide and Low Tide
Tides are caused by the gravitational pull of the Moon and Sun on Earth's oceans. The Moon has the strongest effect due to its proximity. The Moon's gravity causes two tidal bulges in the oceans on opposite sides of Earth. As Earth rotates, different locations experience these bulges as either high or low tides about every six hours. The relative positions of the Moon, Earth, and Sun also influence the monthly tidal cycle, with spring tides resulting in higher high tides and lower low tides.
tides_DrSS.pptx
The document summarizes tides and their causes. Tides are the daily rise and fall of sea levels caused by the gravitational pull of the Moon and Earth's rotation. The Moon's closer proximity to Earth means it has a stronger gravitational pull than the Sun. This pull creates tidal bulges in the oceans on the sides facing and facing away from the Moon. As Earth rotates, different locations experience high and low tides passing through these bulges. Spring tides occur during full and new Moons when the Sun and Moon pull together, creating higher tides. Neap tides happen at half Moons when the Sun and Moon pull at right angles, resulting in lower tides.

Pp udl inroduction
- Universal design (UD) in architecture aims to make buildings and environments accessible to all by removing barriers rather than designing for the average user.
- UDL applies these UD principles to education by ensuring the learning environment (curriculum, materials, teaching) is accessible and beneficial to all students by considering diversity from the start of lesson planning rather than retrofitting afterwards.
- The UDL Guidelines provide a framework to help apply the three UDL principles of engagement, representation, and action and expression to educational practice through multiple means of representation, engagement, and expression.
Slope c
1. Students measured the weight of objects on horizontal surfaces and on slopes of varying degrees of inclination using kitchen and person balances.
2. They found that as the inclination of the slope increased, the measured weight decreased, with steeper slopes showing smaller weights.
3. The conclusion is that placing an object on a sloped surface decreases the measured weight, and weight decreases more with increased slope inclination as the force of gravity has more of a parallel component to the slope.
Spacesuit c
Two groups of students, one in Italy and one in Belgium, conducted experiments with space suits and aluminum foil. They tested how aluminum foil affects electromagnetic signals by calling phones with and without foil. They also dropped balls on surfaces with and without aluminum protection to see how foil reduces impact. The results showed that aluminum foil can stop electromagnetic radiation and lessen the size and depth of impacts when enough layers are used.
Elevator c
An experiment was conducted with people standing on a scale in an elevator to measure changes in weight as the elevator moved up and down. When the elevator went up, participants' weight increased, and when it went down, their weight decreased. This is because as the elevator moves up, it pushes the person up, increasing the force they exert on the scale, while moving down does not provide that additional pushing force, so the measured weight is less.
Magnet ab
1) The document describes an experiment to investigate how the weight of a magnet changes when another magnet is brought near it.
2) When the magnets attract each other, the weight of the lower magnet decreases, and when they repel each other, the weight increases.
3) The Belgian and Italian schools that performed the experiment found similar results, though they used different distances.
Buoyancy c
1. The experiment measured how the buoyant force of different liquids affected the weight of objects by submerging a cube and nuts in distilled water, salt water, and oil and measuring the resultant force.
2. The results showed that the resultant force was always smaller than gravity, with salt water producing the greatest reduction in weight.
3. This demonstrated that salt water best simulates the lower gravity conditions on Mars out of the three liquids, as it most reduced the apparent weight of the objects.
Generating gravity ab
This document summarizes a student experiment to simulate gravity on a spacecraft. The experiment involved spinning glass tubes with attached masses to measure the time taken to make 10 revolutions. Heavier masses took less time to complete 10 revolutions than lighter masses. The results supported the theory that centrifugal force from spinning a spacecraft can generate artificial gravity for astronauts by pushing them towards the outer hull. The document also explained how circular motion and centripetal acceleration relate to creating gravity in space.
Elevator ab
1) Students conducted an experiment to measure changes in weight when riding in an elevator.
2) They used a balance, elevator, camera, and chronometer to record weight while the elevator moved up and down.
3) The results showed that weight increased when the elevator moved down due to gravitational acceleration, and weight decreased when moving up due to deceleration.
Astronauts suit ab
The document summarizes two experiments conducted by Belgian and Italian students to test whether aluminum can protect astronauts from solar radiation and micrometeorites.
The first experiment tested whether aluminum foil could block electromagnetic waves by making phone calls to phones with and without aluminum wrapping. The second experiment dropped balls made of different materials into containers of sand with and without overlying aluminum foil to compare impact sizes.
Both groups found that aluminum blocked electromagnetic waves like solar radiation. They agreed aluminum reduced impact size but the Italians concluded it could fully protect against micrometeorites while the Belgians weren't certain it provided full protection.
Slope ab
Two groups of students - one from Belgium and one from Italy - conducted an experiment to measure the effect of slope on measured weight. They used kitchen scales and a balance scale to measure the weight of objects and people on slopes of varying angles. Both groups found that measured weight decreased with increased slope steepness. However, the Italian group found a greater change in measured weight over different slopes compared to the Belgian group, indicating the slopes in the Italian school were generally steeper.
Magnet on balance c
The students conducted an experiment to determine how the weight of a magnet is affected when another magnet is held above it. They found that if two magnets of the same polarity are held above each other, they repel and the weight increases, while if two magnets of opposite polarity are held above each other, they attract and the weight decreases. The results were the same in both Belgium and Italy because they can be explained by the Law of Universal Gravitation.
Generating gravity c
- Students conducted an experiment to investigate how to generate artificial gravity by spinning a spacecraft. They measured how the time it took to spin rubber caps attached to different masses changed when the mass or spin velocity was altered.
- The Belgian group found that heavier masses required faster spin speeds to remain attached to the rubber caps. The Italian group found that increasing the spin velocity allowed heavier masses to be elevated and that larger spin radii required lighter masses to remain attached.
- The experiment demonstrated that artificial gravity can be generated on a spacecraft by spinning and that both spin speed and radius impact the amount of gravity generated.
Buoyancy ab
The document describes an experiment to measure the effect of different liquids on the apparent weight of objects. Cubes and nuts were measured in distilled water, salt water, and oil. The results showed weight decreased most in oil due to its lower density, similar to how gravity is lower on Mars. While results matched theory, some differences occurred in practice between salt water and oil. The pulling up force from liquids causes apparent weight to decrease as buoyancy increases.
Summary physics
This document discusses several physics experiments related to weight and gravity. It describes experiments to determine how weight is affected by an elevator's movement, slope, nearby magnets, and different liquid environments. The document also explores how centrifugal force from a spinning mass can generate gravity and how aluminum foil can block electromagnetic signals and reduce impact. Key conclusions are that weight increases in an upward elevator, decreases on slopes and near attracting magnets, and is lowest in salt water due to buoyancy.
Buoyancy italy
This physics experiment tested how buoyancy changes with different liquids using a force sensor to measure the weight of objects submerged in distilled water, salt water, and oil. The experiment measured the weight of a cube and nuts in air and then in each liquid. As the density of the liquid increased from distilled water to salt water to oil, the measured weight of the submerged objects decreased, showing that buoyancy increases with the density of the surrounding liquid.
Question 5 group 12
1) The document discusses Newton's third law of motion and how it applies to Brand escaping the black hole in the movie Interstellar.
2) It explains that Cooper detaches his ship, applying a force, which by Newton's third law pushes Brand's ship in the opposite direction, allowing her to escape in a slingshot motion.
3) However, the third law requires equal and opposite forces, and escaping the black hole's strong gravity would require a large force from fuel, which they had already used up. Therefore, the third law alone could not be used to escape the black hole without an additional energy source like fuel.

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.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid

Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.
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.

Question 4 group 11
- 1. Interstellar Made by Camille, Hayco, Joao, Federica, Caterina, Arianna
- 2. What causes the huge waves on the ‘water planet’? • On our planet the tides are caused by the moon. The moon has a just a little bit of attraction. This causes our little tides and quite small waves. • On the Water Planet the waves are caused by Gargantua. This black hole generates a lot of attraction. This is the reason for these big waves. • Miller’s Planet surface is characterized by the constant movement of water. Huge waves are caused by a seismic event due to the intense gravity produced by the black hole. These forces generate the incessant swells and the propagation of waves.
- 3. • The waves are very big, but if you compare the two forces from the moon and Gargantua. You’re able to understand that these waves are pretty normal. • They followed the rules of nature and didn’t exagerate.
- 4. Does it really exists? • Gargantua doesn’t exist but there are many black holes. Gargantua could have existed. • They created Gargantua in this film, they recreated a real black hole with the same symptoms. • There is proof of black holes but none for Gargantua.
- 5. WHY DID THEY DECIDE TO CALL THE BLACK HOLE GARGANTUA? THE BLACK HOLE TAKES THE NAME FROM A NOVEL CALLED «THE LIFE OF GARGANTUA AND OF PANTAGRUEL», OF THE SIXTEENTH CENTURY WRITTEN BY FRANCOIS RABELAIS. THE MAIN CHARACTER GARGANTUA, IS A GIANT KNOWN FOR HIS FORMIDABLE HUNGER. SO JUST LIKE THE BLACK HOLE, THIS GIANT DEVOURS EVERYTHING HE FINDS.
- 6. • WHICH FORCE CAUSES THE TIDES? • On Miller’s planet the tides are caused by the black hole Gargantua.This process is what happens with the Moon on the earth, but the Moon is once much closer to the Earth and we have huge tides. These tidal forces cause planetary distortions (the planet becomes a sort of football shape) and as the Moon spins, it is essentially being kneaded by the tidal forces. In the case of Interstellar there is a sort of gravitational attraction too: Miller's planet is the equivalent of the Moon and Gargantua is the equivalent of the Earth. • Practically the Gargantua’s attraction causes on Miller’s planet oscillations: when the planet moves to the right, Gargantua pulls it back to the left. This constant rocking back and forth on Miller’s planet under Gargantua’s intense tidal force means that those gigantic waves slosh about on the planet surface.
- 7. • WHY ARE THE WAVES SO HIGH? • THE MOON’S GRAVITY DOES NOT ONLY PULL ON THE EARTH’S MANTLE BUT ALSO ITS OCEANS. THE WATER OVER THE SUBLUNAR SIDE IS CLOSER AND IS PULLED TOWARDS THE MOON FASTER THAN THE SOLID MANTLE BENEATH, CREATING A BULGE. ON THE OPPOSITE (ANTIPODAL) SIDE, SOMETHING DIFFERENT HAPPENS.
