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.
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.

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. MEANING OF
MEASUREMENT
Measurement is the process of observing and recording the observations that are
collected as part of a research effort.
To get the exact measurement of an object we make use of tools used in the field of
science, especially in physics called measuring instrument.
Examples of such instrument are chemical balance, spring balance, meter rule, caliper,
micrometer screw guage, clock, thermometer etc.
3. MEASUREMENT OF MASS
Mass is the quantity of matter contained in a body.
The instrument used in measuring mass is chemical/beam balance.
It is a scalar quantity & measured in kilogram (kg).
Mass is a fundamental quantity & is constant from place to place.
4. MEASUREMENT OF WEIGHT
Weight is the earth pull on a body or the downward force produced when a mass is in a
gravitational field.
The instrument used in measuring weight is spring balance.
It is a vector quantity & measured in newton (N).
Weight is a derived quantity & varies from place to place.
Relationship Between mass & weight
W=mg
Where: W=weight (N); m=mass (kg) & g=acceleration due to gravity (m/s2)
5. MEASUREMENT OF LENGTH
Length is simply distance extended. It is a fundamental quantity & measured in meters
(m).
Length can be measured using tape rule, meter rule, caliper, vernier caliper and
micrometer screw guage
6. MEASUREMENT OF TIME
Time can be defined as the interval between events.
It is a fundamental quantity & measured in seconds(s).
Time can be measured using stop watch/clock
