The Moon is Earth's only natural satellite, located about 384,000 km away. It was formed 4-5 billion years ago from debris after a collision between Earth and a Mars-sized object. The Moon has no atmosphere and extreme temperature variations, and its features include mountains, rills, large impact craters, and dark basaltic plains called maria. It always keeps the same face towards Earth due to synchronous rotation as it revolves around our planet every 27 days.

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.

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.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Our moon
1. A look at our nearest
neighbor in Space!
The Moon
Free powerpoints at http://www.worldofteaching.com
2. What is the Moon?
• A natural satellite
• One of more than 96 moons in
our Solar System
• The only moon of the planet
Earth
3. Location, location, location!
• About 384,000 km
(240,000 miles)
from Earth
• 3,468 km (2,155
miles) in diameter
(about ¼ the size of
Earth)
4. Birth of the Moon
• “Born” 4-5 billion
years ago
• Formed from impact
of Mars-sized
“planetesimal” on
Earth
• Debris from both
objects melted
together to form the
Moon
5. Cut to the Core
• 3 major divisions
of the Lunar
interior
• Crust - average
thickness of about
70 kilometers
• Mantle
• Core - radius is
between 300 and
425 kilometers
6. The Moon’s Surface
• No atmosphere
• No liquid water
• Extreme
temperatures
– Daytime = 130°C
(265°F)
– Nighttime = -190°C
(-310 °F)
• 1/6 Earth’s gravity
7. Lunar Features - Highlands
• Mountains up to 7500 m
(25,000 ft) tall
• Rilles (trenchlike
valleys)
8. Lunar Features - Craters
• Up to 2500 km (1,553 miles) across
• Most formed by meteorite impact on the Moon
• Some formed by volcanic action inside the Moon
9. Lunar Features - Maria
• Originally thought to be
“seas” by early
astronomers
• Darkest parts of lunar
landscape
• Filled by lava after crash
of huge meteorites on
lunar surface 3-4 billion
years ago
• Mostly basalt rock
11. Movements of the Moon
• Revolution – Moon orbits
the Earth every 27 and 1/3
days
• The moon rises in the east
and sets in the west
• The moon rises and sets
50 minutes later each day
• Rotation – Moon turns on
its axis every 27 days
• Same side of Moon
always faces Earth
12. Far Side of the Moon
• First seen by Luna 3
Russian space probe in
1959
• Surface features
different from near
side
– More craters
– Very few maria
– Thicker crust
13. It’s Just a Phase
• Moonlight is reflected
sunlight
• Half the moon’s surface is
always reflecting light
• From Earth we see
different amounts of the
Moon’s lit surface
• The amount seen is called
a “phase”
14. Waxing and Waning
• New moon
• Waxing Crescent moon
• First Quarter moon
• Waxing Gibbous moon

18. Lunar Eclipses
• Moon moves into
Earth’s shadow – this
shadow darkens the
Moon
– Umbra
– Penumbra
• About 2-3 per year
• Last up to 4 hours
19. Solar Eclipses
• Moon moves between
Earth and Sun
• Moon casts a shadow
on part of the Earth
• Total eclipses rare –
only once every 360
years from one
location!
20. The Tides
• Tides caused by pull of Moon’s gravity on Earth
• High tide –
– Side facing Moon and side away from Moon
– Every 12 hours, 25 ½ minutes
• Low tide –
– On sides of Earth
