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.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
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 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.
2. `Seismic
Waves
These are the waves of
energy caused by the sudden
breaking of rock within the
earth or an explosion. They are
the energy that travels
through the earth and
recorded on seismographs.
3. `Types Seismic
Waves
Body waves - arrive before the surface waves
emitted by an earthquake. These waves are of a
higher frequency than surface waves.
Surface waves(L-Waves) - are of a lower
frequency than body waves, and are easily
distinguished on a seismogram as a result. Though
they arrive after body waves, it is surface waves
that are almost entirely responsible for the damage
and destruction associated with earthquakes. This
damage and the strength of the surface waves are
reduced in deeper earthquakes.
5. `Primary Waves
Primary wavesare “compression waves”.
They push and pull the rocks of the earth's surface. They can move
through solid rock and fluids like water or the liquid core layers of the earth And
first to 'arrive' at a seismic station.
6. `
Primary waves push and pull on the rocks through which
they are traveling. This creates a back and forth movement
on the Earth's surface. This is just like sound waves pushing
and pulling the air. Have you ever heard a big clap of thunder
and heard the windows rattle at the same time? The windows rattle because the
sound waves were pushing and pulling on the window glass much like P-waves
push and pull on rock.
Primary Waves
7. `Secondary Waves
Secondary waves travel slower than primary waves. Also called “shear waves
"or “Transverse Waves”.
They create a side to side motion in the rocks through which they are
traveling.
8. `Secondary Waves
Unlike the other earthquake waves, S-waves cannot
travel through water or the liquid rock of the Earth's
core layer. They can Travel through solid only-waves will rock buildings side-
to-side.
9. `Remember...
Primary WavesSecondary Waves
Also Called as Compression Waves.
They Push and Pull the rock in the earth’s surface
Also Called as Shear/Transverse Waves.
They Push and Pull the rock in the earth’s surface
11. `Surface Waves(L-Waves)
Land waves move along the surface of the earth and cause it to move
up and down like something bobbing on the surface of the ocean.
12. `Surface Waves(L-Waves)
Land waves only move along the surface of the earth.
Their speeds vary depending on the material, rock or soil,
forming the surface. These waves cause the surface to
move up and down. These are the waves that cause
The to buildings and other structures
during an earthquake.
13. `
Named after A.E.H. Love, a British mathematician
who worked out the mathematical model for this
kind of wave in 1911.
Love Waves
Love waves travel with a lower velocity than P or
S waves, but faster than Rayleigh waves. These
waves travels in lithosphere only.
14. `
These waves are a type of surface acoustic
wave that travel on solids
Rayleigh Waves
Named for John William Strutt, Lord
Rayleigh, who mathematically predicted
the existence of this kind of wave in 1885.
Rolls along the ground just like a
wave rolls across a lake or an ocean.
Because it rolls, it moves the ground up
and down, and side-to-side in the same
direction that the wave is moving.
Most of the shaking felt from an
earthquake is due to the Rayleigh wave,
which can be much larger than the other
waves.
16. `Remember...
Love Waves
travels through lithosphere only. Has
Low Velocity but faster than Rayleigh
waves.
Rayleigh Waves
travel on solids and Rolls along the ground
17. `Questions:
1. Other term for primary waves and secondary waves
2. Differentiate the P and s waves
3.Love waves are named after a mathematician. What is the name of the
mathematician ?
4.How about rayleigh waves. What is the name of the mathematician ?
