Revolution & rotation
The document discusses the differences between revolution and rotation as they relate to Earth. Revolution is the movement of Earth around the sun, taking 365.25 days to complete at a speed of about 18 miles per second. Rotation is the spinning of Earth on its axis, taking 24 hours to complete at a speed of about 1,038 miles per hour. Examples are given of objects revolving or rotating to further illustrate the concepts.
The Earth, Rotation and Revolution
The Earth has two movements: rotation and revolution. Rotation is the Earth spinning on its axis every 24 hours, causing day and night. Revolution is the Earth orbiting the Sun every 365 days, causing seasons and years. Due to these movements, different parts of the Earth receive varying amounts of sunlight, influencing climate zones and seasons. The tilt of the Earth's axis and its position in orbit also affect the length of daylight and temperature changes throughout the year.

Cartoon: I drew a cartoon showing Earth rotating on its axis while also revolving around the Sun. Night and day are passing by, and the seasons are changing as Earth makes its yearly journey. In the speech bubbles, Earth says "Wow, it sure gets busy making a full rotation and revolution each day and year! No wonder humans had a hard time figuring all this out - it must look really confusing from down here on the surface."
Poem:
Spinning round and round each day,
Bringing light then taking it away.
Wobbling slightly as I go,
On my yearly trip around the glowing glow.

The weather and seasonal changes affect plants, animals, and their surroundings through various adaptations. Adaptations like whiskers, sharp teeth, webbed feet, and wings help animals survive in their environments. Seasonal behaviors like migration, hibernation, and dormancy allow animals to respond to changes in temperature, light levels, and precipitation. Camouflage also provides protection by allowing animals to blend into their surroundings.
Gyro
A gyrocompass uses a spinning wheel or gyroscope mounted on gimbals to automatically point toward geographic north. It maintains its axis of rotation regardless of the motion of the ship or airplane it is mounted on. By measuring the tilt of the gimbal frame, the gyrocompass can determine the amount of pitch, roll and yaw. It is useful for navigation where magnetic compasses are ineffective near the poles. The document outlines the components, working principle, advantages and limitations of a gyrocompass. It then provides specifications for constructing a basic 3-axis gyrocompass and estimates the total cost.
The Seasons
The document discusses various aspects of the Earth's rotation, revolution, and tilt, and how these factors cause the seasons. It explains that the seasons are due to the tilt of the Earth's axis, not our distance from the Sun. When the northern hemisphere tilts toward the Sun, it receives more direct sunlight, causing summer.
Seasons of the earth
The Earth's seasons are caused by its axial tilt of 23.45 degrees, not variations in its distance from the Sun. This tilt means the Northern and Southern Hemispheres receive sunlight at different angles throughout the year, causing summer to be warmer than winter. The solstices mark the longest and shortest days of the year, while the equinoxes occur when day and night are equal in length and mark the first days of spring and fall.
Gyro compass navigation
Gyro compasses use north-seeking gyroscopes mounted on two gimbals to determine heading, relying on gyroscopic inertia, gravity, and precession. On ships, primary gyro compasses are oriented north-south for navigation and handling, while auxiliary gyros are east-west for combat systems. Gyro repeaters display heading information on the bridge and centerline, while gyro inputs are also used for command and control systems and weapons fire control computers. Gyro compasses are subject to inherent errors from factors like friction, ship motion, electronics, and power fluctuations that must be accounted for through adjustment.

#11 The Sun as an Energy Source
The Sun is the ultimate source of energy for life on Earth. It is 1 million times bigger than Earth but Earth only receives 1 billionth of its energy output due to its distance of 93 million miles. Some of the Sun's radiation is reflected or radiated back into space while enough remains to warm Earth and power its ecosystems. Earth's rotation causes day and night while its revolution around the Sun takes 365 days to complete. Its tilted axis and round shape cause the seasons as different hemispheres receive more direct sunlight throughout the year. Latitude affects climate zones, with the hottest temperatures at the equator and coldest at the poles due to the angle of the Sun's rays.
datum
Spheroid, datum, projection, and coordinate systems are used to locate positions on Earth. A spheroid is a mathematical model that approximates the Earth's shape as an oblate spheroid. A datum defines the reference frame for latitude and longitude coordinates and relates the spheroid to the Earth's center. Projections transform 3D spheroid coordinates onto a 2D surface like a map, introducing some distortion of shapes, areas, distances or directions. Common projections include transverse Mercator, UTM, and lambert conformal conic. Coordinate systems then allow measurement of positions on the projected 2D surface. Understanding these concepts is important for accurately locating geographic features.
Theory of Gyrocompass
A gyroscope, not to be confused with gyrocompass, is a spinning wheel mounted on gimbal so that the wheel's axis is free to orient itself in any way. When it is spun up to speed with its axis pointing in some direction, due to the law of conservation of angular momentum, such a wheel will normally maintain its original orientation to a fixed point in outer space (not to a fixed point on Earth).

Motions of earth
The document discusses rotation and revolution. Rotation is defined as the spinning of a planet on its axis, which for Earth is tilted at 23.5 degrees. The Earth's rotation causes day and night as it spins once every 24 hours. Revolution is defined as the movement of a planet around another object, in this case the Earth revolving around the Sun. It takes the Earth 365.25 days to complete one revolution around the Sun, defining a year. The tilt of the Earth's axis as it revolves causes the seasons, not the Earth's distance from the Sun.
Rotation and revloution
The document discusses the rotation and revolution of Earth. It explains that rotation is Earth spinning on its axis, which causes day and night. Revolution is Earth orbiting the Sun, which takes 365.242 days and causes the seasons as Earth's tilted axis changes which hemisphere is closer to the Sun throughout the year. Seasonal changes occur due to both Earth's tilt on its axis during rotation and its revolution around the Sun.

Plate Tectonics
The document discusses plate tectonics and the structure and dynamics of the Earth's interior. It describes how the crust is broken into plates that move atop the mantle due to convection currents, and the three types of plate boundaries: divergent where plates move apart, convergent where they move together, and transform where they slide past each other. It provides examples of associated geological features like mid-ocean ridges, subduction zones, volcanoes, and earthquakes.
Tides
Tides are caused by the gravitational pull of the moon and sun on Earth's oceans. Each day there are two high tides and two low tides as the moon revolves around Earth. Spring tides result in the highest and lowest tides and occur during a new or full moon when the sun, Earth, and moon are aligned. Neap tides have a smaller range between high and low tides and happen during the first and last quarter moon phases when the sun, Earth, and moon form a right angle.
Eclipses
Solar eclipses occur during the day when the moon passes between the Earth and sun, either fully or partially blocking the sun's light. Lunar eclipses happen at night during a full moon when the moon moves behind Earth into its shadow, resulting in either a total or partial eclipse where some or all of the moon is covered by the Earth's shadow. The document describes the differences between total and partial solar and lunar eclipses in terms of the moon passing through different parts of the sun or Earth's shadow.
Phases of the Moon
The document discusses the phases of the moon. It explains that the moon gets its light from the sun and revolves around the earth every 28-31 days. As it revolves, the shape of the moon changes through phases such as new moon, crescent moon, quarter moon, gibbous moon, and full moon depending on how much of the illuminated side is visible to observers on earth.
Solstices & Equinoxes
The document discusses the earth's solstices and equinoxes. The winter solstice occurs on December 21/22 and has the shortest day of the year. The summer solstice is on June 21/22 and has the longest day. The equinoxes happen around March 21 and September 22, marking equal amounts of day and night and the first days of spring and fall.
Seasons
Earth's seasons are caused by its revolution around the sun and the tilt of its 23.5 degree axis. During summer, the northern hemisphere tilts toward the sun, receiving direct sunlight and warmer temperatures. In winter, the northern hemisphere tilts away from the sun and receives indirect sunlight, resulting in cooler temperatures. Spring and fall occur when both hemispheres receive equal amounts of indirect sunlight. The equator experiences no seasons as it always receives direct sunlight.
Geocentric vs. Heliocentric Models
The document compares the geocentric and heliocentric models of the solar system. The geocentric model, proposed by Ptolemy, placed Earth at the center, which was believed by the Catholic Church. The heliocentric model, proposed by Copernicus, correctly placed the Sun at the center. Evidence like seasons, Galileo's telescope observations, Kepler's laws of planetary motion, and Newton's theory of gravity supported the heliocentric view, though the Catholic Church originally opposed it.
Solar System
The document provides an overview of the objects in our solar system, including the sun, eight planets, asteroids, comets, and meteoroids. It describes the key characteristics of each, such as the inner terrestrial planets being made of rock and metal versus the outer gas giants consisting mostly of hydrogen and helium. Images and facts are presented about traits like Venus' dense carbon dioxide atmosphere, Jupiter's Great Red Spot, and Neptune's blue color from methane gas.

South African Journal of Science: Writing with integrity workshop (2024)Academy of Science of South Africa
A workshop hosted by the South African Journal of Science aimed at postgraduate students and early career researchers with little or no experience in writing and publishing journal articles.A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
