Thomas Alva Edison was an American inventor who developed many pioneering devices, including the phonograph, the motion picture camera, and a long-lasting practical electric light bulb. According to a story, when Edison was a child his teacher deemed him addled and told his mother he could no longer attend school, but his mother recognized his genius and taught him herself at home. Later in life, Edison discovered a note from the teacher calling him addled, and cried for hours realizing how much his mother had done for him. Edison held over 1,000 patents and won many awards for his inventions, leaving a significant impact on technology and daily life around the world.
Albert’s class was on the history teacher Mr. Braun asked Albert if the Prussians defeated the French to Waterloo. Albert told him that he didn’t know and he must have forgotten. This irritated the teacher. He asked Albert, why? Albert replied that he didn’t see a point in learning dates. One could learn about them from books. Ideas are more important than facts and figures. The teacher attributed to Albert that he didn’t believe in education. He talked in a sarcastic manner. Albert told him that education should be about ideas and not facts. The teacher said that Albert was a disgrace to be there Albert felt miserable when he left the school that afternoon.
He didn’t like this school. He would have to come to it again. He lived in a small room. It was one of the poorest quarters of Munich. The landlady beat her children regularly. Her husband came every Saturday and drank in the evening. He then beat her. He didn’t like the children’s crying every time. He told these things to Yuri. He hated the atmosphere of slum violence. Next time his cousin [elsa] came to Munich. She told Albert that if he tried he could pass the examination. There were more stupid boys than him. Moreover, passing the examination was not difficult. It was simply just to be able to repeat in the examination that Elsa that he was not good at learning things by heart. He liked music as it gave him comfort. Albert didn’t like to remain in school. He met Yuri after six months. He had an idea. He told Yuri that if he had a medical certificate that he suffered from a nervous breakdown, he could get rid of school. He asked Yuri if he had a doctor friend. Yuri told him that he had in Dr. Ernest Weil. However, Yuri told him not to deceive him. He must be frank with him. When Albert visited Dr. Ernest Weil he had really come near a nervous breakdown. Dr. Ernest issued him the certificate. His fees were that he should serve Yuri with a meal. Albert told Dr. Ernest about his future plans.
He would go to Milan. He hoped to get admission into an Italian college or institute. It was possible from the comments of the Mathematics teacher, Mr. Koch. Yuri told him to get a reference in writing from the Mathematics teacher before going to the head teacher. Mr. Koch, the mathematics teacher encouraged him.

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.

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. Thomas Alva Edison (February
11, 1847 – October 18, 1931) was an
American inventor and businessman.
He developed many devices that
greatly influenced life around the world,
ncluding the phonograph, the motion
picture camera, and the long-lasting,
practical electric light bulb.
3. One day Thomas Edison came home and gave a paper
to his mother. He told her, “My teacher gave this paper to
me and told me to only give it to my mother.”
His mother’s eyes were tearful as she read the letter
out loud to her child: Your son is a genius. This school is
too small for him and doesn’t have enough good teachers
for training him. Please teach him yourself.
After many, many years, after Edison’s mother died
and he was now one of the greatest inventors of the
century, one day he was looking through old family
things. Suddenly he saw a folded paper in the corner of a
drawer in a desk. He took it and opened it up. On the
paper was written: Your son is addled [mentally ill]. We
won’t let him come to school any more.
Edison cried for hours and then he wrote in his
diary: “Thomas Alva Edison was an addled child that, by a
hero mother, became the genius of the century.”
A short story of Edison Mother
5. The inventor Thomas Alva Edison (in
the USA) experimented with thousands
of different filaments to find just the
right materials to glow well and be long-
lasting.
In 1879, Edison discovered that a
carbon filament in an oxygen-
free bulb glowed but did not burn up for
40 hours.
6. History. David Edward
Hughes invented a carbon microphone in the
1870s. The first microphone that enabled
proper voice telephony was the (loose-
contact) carbon microphone (then
called transmitter). This was independently
developed by David Edward Hughes in England
and Emile Berliner and Thomas Edison in the US.
7. The Quadruplex telegraph is a
type of electrical telegraph which
allows a total of four separate
signals to be transmitted and
received on a single wire at the same
time (two signals in each
direction). Quadruplex telegraphy
thus implements a form of
multiplexing.
8. PHONOGRAPH
The phonograph was invented in 1877 by Thomas
Edison.
While other inventors had produced devices that
could record sounds, Edison's phonograph was
the first to be able to reproduce the recorded sound.
His phonograph originally recorded sound onto a
tinfoil sheet wrapped around a rotating cylinder.
9. MOTION PICTURE CAMERA
It was to provide a visual accompaniment to the
phonograph that Edison commissioned Dickson, a
young laboratory assistant, to invent a motion-
picture camera in 1888.
Dickson's camera, the Kinetograph, initially
imprinted up to 50 feet (15 metres) of celluloid film at
the rate of about 40 frames per second.
10. ELECTRIC POWER DISTRIBUTION
Swan and Edison later set up a joint
company to produce the first practical
filament lamp, and Edison used his direct-
current system (DC) to provide power to
illuminate the first New York electric street
lamps in September 1882.
11. MEMEOGRAPH
Thomas Edison is credited with inventing
the first mimeograph copying system.
Dick, whose company licensed Edison's
technology, invented the mimeo stencil and
marketed the first commercial mimeograph in
1887.
Once text is cut (or typed) into the stencil, the
stencil is wrapped and fastened around a
cylinder
12. he failed over 1,000 times in trying to find the
right filament for his light bulb. That he
acknowledged openly. But he also tried any
number of other experiments, failing miserably
often, so I'm not sure there's a complete
count. He, like most other successful
inventors and entrepreneurs, knew that failing
was the road to success, and wasn't afraid of
doing so or trying things outside the box.

14. THOMAS EDISON DEATH
Death. Edison died of complications of
diabetes on October 18, 1931, in his home,
"Glenmont" in Llewellyn Park in West Orange,
New Jersey, which he had purchased in 1886 as
a wedding gift for Mina.
He is buried behind the home.
Edison's last breath is reportedly contained in
a test tube at the Henry Ford Museum.
