The document compares the relative sizes of objects in our solar system and Milky Way galaxy. It shows that Earth is tiny compared to the Sun, and the Sun is tiny compared to the Milky Way galaxy. The Milky Way galaxy itself contains hundreds of billions of stars and is just one of hundreds of billions of galaxies in the visible universe. The vast scale of the universe reveals the immense knowledge and power of its Creator.
The Universe is a beautiful place full of captivating galaxies, stars, planets, asteroids, and infinite other bodies. Stars probably hold the title for the most fascinating celestial objects there. From growing up with stories of how stars are actually angels to finally knowing that the Sun is a star as well. While the Universe is still a mystery to us, there is a lot we know. Here are the ten biggest stars in the Universe that are known to mankind till date.
The term planet is ancient, with ties to history, astrology, science, mythology, and religion. Several planets in the Solar System can be seen with the naked eye. These were regarded by many early cultures as divine, or as emissaries of deities.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

5. As we have compared the
Earth with Sun
Now !!
Start comparing the Sun with
the Universe
6. The closest star to the Sun is only 7000 times further than the edge of our solar system.
This map shows all of the stellar systems that lie within 12.5 light years from us.
7. This map is a plot of the 1500 most luminous stars within 250 light years.
All of these stars are much more luminous than the Sun and most of them
can be seen with the naked eye. About one third of the stars visible with the
naked eye lie within 250 light years, even though this is only a tiny part of our galaxy.
8. The Sun is
located in the
Orion Arm - a
fairly minor arm
compared with
the Sagittarius
Arm,
which is
located closer
to the galactic
centre.
The map shows several stars visible with the naked eye which are located deep within the
Orion arm. The most notable group of stars here are main stars in the constellation of Orion
-from which the spiral arm gets its name. All of these stars are bright giant and supergiant
-stars, thousands of times more luminous than the Sun. The most luminous star on the map
-is Rho Cassiopeia - to us 4000 light years away, it is a dim naked eye star, but in reality
-it is a huge supergiant star 100 000 times more luminous than our Sun.
9. A spiral galaxy of at least two hundred billion stars. Our Sun is buried deep within the
Orion Arm about 26 000 light years from the centre. Towards the centre of the Galaxy
the stars are packed together much closer than they are where we live. Notice also the
presence of small globular clusters of stars which lie well outside the plane of the Galaxy,
and notice too the presence of a nearby dwarf galaxy - the Sagittarius dwarf –
which is slowly being swallowed up by our own galaxy.
10. Although the Milky Way is but one of billions of galaxies in the universe,
the Galaxy has special significance to humanity as
it is the home of the solar system.
As a guide to the relative physical scale of the Milky Way,
if the galaxy were reduced to 130 km (80 mi) in diameter,
the solar system would be a mere 2 mm (0.08 in) in width.
11. Number of large galaxies within 500 000 light years = 1
Number of dwarf galaxies within 500 000 light years = 9
Number of stars within 500 000 light years = 225 billion .
The Milky Way is surrounded by several dwarf galaxies, ypically containing a
few tens of millions of stars, which is insignificant compared with the number of
stars in the Milky Way itself. This map shows the closest dwarf galaxies,
they are all gravitationally bound to the Milky Way requiring billions of years to orbit it.
12. Can you find the
Milky Way in this??
Our Milky Way galaxy
is part of Local Group
& it is in centre
Number of galaxy groups within 100 million light years = 200
Number of large galaxies within 100 million light years = 2500
Number of dwarf galaxies within 100 million light years = 25 000
Our galaxy is just one of thousands that lie within 100 million light years. The above map
shows how galaxies tend to cluster into groups, the largest nearby cluster is the Virgo
cluster a concentration of several hundred galaxies which dominates the galaxy groups
around it. Collectively, all of these groups of galaxies are known as the Virgo Supercluster
The second richest cluster in this volume of space is the Fornax Cluster, but it is not
nearly as rich as the Virgo cluster. Only bright galaxies are depicted on the map, our
galaxy is the dot in the very centre.
13. Galaxies and clusters of
galaxies are not uniformly
distributed in the Universe,
instead they
collect into vast clusters
and sheets and walls of
galaxies interspersed with
large voids in
which very few galaxies
seem to exist. The map
above shows many of
these superclusters
including the Virgo
supercluster - the minor
supercluster of which our
galaxy is just a minor
member. The entire map
is approximately 7 percent
of the diameter of the entire
visible Universe.
14.
15. This map attempts to show
the entire visible Universe.
The galaxies in the universe
tend to collect into vast
sheets and superclusters of
galaxies surrounding large
voids giving the universe a
cellular appearance.
Because light in the
universe only
travels at a fixed speed, we
see objects at the edge of
the universe when it was
very young up to 14 billion
years ago.
16. Now Stop Comparing
& start thinking about the
Knowledge & Power
of the Creator by seeing this Creation
Don’t you ever ponder over the signs of the Creator ???
All Praise is to the Lord of the Universe
The Almighty, The all-Knowing, The Omnipotent
Can you imagine the Knowledge & Power
Of the creator of this universe???
