The document provides an overview of Earth science topics including the origin of the universe, solar system, and Earth. It discusses theories of how the universe and solar system formed, including the nebular hypothesis which proposes that the solar system condensed from a giant cloud of gas and dust. Key events included gravitational collapse of the solar nebula forming the Sun and planets condensing from the disk as it rotated and cooled.

Embracing GenAI - A Strategic ImperativePeter Windle
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.

25. CONCEPTS
Cosmology - is the study of
the universe, including its
properties, structure and
evolution.
26. Introduction
Universe galaxy solar system
Universe: all of space, including all matter and
energy everywhere
Galaxy: a clump of stars within a universe
Solar System: one star and its surrounding
planets
Star: matter that emits huge amounts of energy
Planet: matter that revolves around a star

33. The Origin of the Universe
The Big Bang Theory
(Georges Lemaitre, 1927)
“Time zero” 10 to 15
Billion years ago
all matter was compacted into
a teeny tiny little ball
little ball was extremely hot,
dense and under enormous
pressure
small, dense ball expanded
rapidly hurling matter and
energy in all directions
35. http://rainbow.ldeo.columbia.edu/courses/v1001/7.html
- A split second later there
was instantaneous filling of
space with all matter
=Inflation
-as the universe inflated it
was flooded with energy and
matter (gravity and
electricity)
Building a Universe
36. Building a Universe
After 3 minutes, quarks started to join and form
atoms like hydrogen
After 1,000,000 years gases began to curdle into
strands with dark holes in between
After 300,000,000 years the strands clumped
clouds stars and galaxies
We can still see the afterglow today! (think of a
piece of firewood after the fire is out)

39. The Evidence
There is an abundance of light elements (hydrogen and helium) in
the universe.
The universe cooled as it expanded so that today the Cosmic
Microwave Background (CMB) radiation corresponds to a
temperature of 2.7 K.
As the galaxy moves away, the wavelength of light gets longer
and shifts to the red end of the visible spectrum. This is called
red-shift.

43. CREATIONIST THEORY
According to the Genesis of the Bible’s
Old testament, the creation of the
entire cosmos (universe) took place in
six days. The biblical creation story tells
that God created the universe.
44. CREATIONIST THEORY
7 DAYS OF CREATION
Day 1 - God created light and separated the
light from the darkness, calling light "day"
and darkness "night."
Day 2 - God created an expanse to separate
the waters and called it "sky."
Day 3 - God created the dry ground and
gathered the waters, calling the dry ground "land," and the
gathered waters "seas." On day three, God also created
vegetation (plants and trees)
45. CREATIONIST THEORY
Day 4 - God created the sun, moon, and the stars
to give light to the earth and to govern and
separate the day and the night. These would also
serve as signs to mark seasons, days, and years.
Day 5 - God created every living creature of the
seas and every winged bird, blessing them to
multiply and fill the waters and the sky with life
46. CREATIONIST THEORY
Day 6 - God created the animals to fill the earth.
On day six, God also created man and woman
(Adam and Eve) in his own image to commune
with him. He blessed them and gave them every
creature and the whole earth to rule over, care for,
and cultivate.
Day 7 - God had finished his work of
creation and so he rested on the seventh
48. STEADY STATE THEORY
infinite Universe Theory or Continuous Creation
*Proposed by Hermann Bondi, Thomas Gold, And Sir Fred
Hoyle
*The universe has no beginning or end.
*The universe is in the process of constant creation and the
matter is being continually replenished in one place and
being destroyed elsewhere.
*Believes that as galaxies move apart, new matter appears
between them and forms new galaxies.'
*As new galaxies form, old ones die, with the universe
always having the same density
58. Origin of Our Solar System ~ 4.5
billion years ago
Nebular Theory – our Solar System
formed from a giant, swirling cloud of gas
& dust.
Solar nebula – name given to the cloud
of gas from which our own Solar System
formed
The nebular theory holds that our Solar
System formed out of a nebula that
collapsed under its own gravity.
60. Gravitational Collapse
The solar nebular was initially somewhat spherical
and a few light years in diameter.
– very cold
– rotating slightly
It was given a “push” by some event.
– perhaps the shock wave from a nearby supernova
As the nebula shrank, gravity increased, causing
collapse.
As the nebula “falls” inward, gravitational potential
energy is converted to heat.
– Conservation of Energy
As the nebula’s radius decreases, it rotates faster
– Conservation of Angular Momentum
62. Orderly Motions in the
Solar System
The Sun formed in the very center of the nebula.
– temperature & density were high enough for nuclear
fusion reactions to begin
The planets formed in the rest of the disk.
This would explain the following:
– all planets lie along one plane (in the disk)
– all planets orbit in one direction (the spin direction of the
disk)
– most planetary orbits are near circular (collisions in the
disk)
63.
64. A summary
A. solar nebula
B. gravity causes contraction into rotating
disk
C. Temp and pressure gets so high that
nuclear fusion occurs sun
D. Collisions between particles of dust and
gas occur clumping
E. These form planets
65. Formation of the
Inner Planets
Small grains stick to one another via
electromagnetic force until they are massive
enough to attract via gravity to form...
planetesimals which will combine near the Sun
to form rocky planets!
