Nicolaus Copernicus was a Polish astronomer born in 1473 who developed a model of the universe where the Sun, not the Earth, was at the center. He published his theory, called heliocentrism, in 1543 just before his death, contradicting the geocentric model of Ptolemy that had been accepted for centuries. Copernicus's revolutionary theory helped start modern astronomy and a scientific revolution by establishing a new view of our solar system and the universe.
Nicolaus Copernicus set off a scientific revolution with his Sun-centered view of the Universe.

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.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
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.

2. Nicolaus Copernicus was an
astronomer who changed how
we viewed the positioning of
the Sun, Earth and other
celestial objects in space. He
reasoned that it was the Sun at
the middle of the known
Universe and not the Earth, an
idea that was strongly opposed
at the time. Read on for
interesting facts, quotes and
information about the
scientist Nicolaus Copernicus.
3. Copernicus was born on the 19th of February, 1473 and
died on the 24th of May, 1543.
He was born in Thorn, Royal Prussia, part of the
Kingdom of Poland at the time.
The astronomical model that Copernicus developed
was called heliocentrism (helios means Sun).
It has the Sun motionless at the center
of the Universe while the Earth and
other planets rotate around it in
circular paths.
4. A much earlier geocentric model (geo means Earth)
created by Ptolemy featured Earth at the center of the
Universe. This model was used by astronomers and
other scientists for centuries before Copernicus
developed his heliocentric model.
Many believe that the theory and ideas put forward by
Copernicus started modern astronomy and were the
beginning of a scientific revolution.
Copernicus's work ‘On the Revolutions of Celestial
Spheres’ was published shortly before he died in 1543.
Copernicus's skills were not limited to just astronomy.
Among other things, Copernicus was also a physician,
scholar, economist, translator, mathematician, artist
and diplomat.
5. The chemical element Copernicum is named after
Copernicus. It has the symbol Cn and atomic number
112.
Famous Nicolas Copernicus quotes include: “Finally
we shall place the Sun himself at the center of the
Universe.”
“For when a ship is floating calmly along, the sailors
see its motion mirrored in everything outside, while
on the other hand they suppose that they are
stationary, together with everything on board. In the
same way, the motion of the earth can unquestionably
produce the impression that the entire universe is
rotating.”
