FROM A BULLET TO A MOULD History does not always move forward in pomp and ceremony, and even seemingly unin spiring events can change its course. A bullet fired from 19-year-old Serbian Gavri- 10 Princip's pistol not only killed the Archduke Franz Ferdinand, but triggered a World War that claimed more than one million lives. A mould, noticed by chance, in Alexander Fleming's unclean petri dish, led to the discov ery of penicillin, the medicine that eventually saved millions of lives, and marked a milestone in the history of medicine. Inventions, discoveries, explorations... all have contributed to the progress of mankind. On the darker side, you see vicious battles, dev astating epidemics, and crimes. This issue of 'Tell Me Why,' tells you about some such landmarks in the history of our world. What makes the Colosseum a landmark in world history? The Colosseum of Ancient Rome is one of the landmarks of world history, for it is a testi monial to the greatness of the Roman Empire. This giant am phitheatre was built in the centre of Rome. The construction was started by the Em peror Vespasian in AD 72, and completed in AD 80 by his successor and heir, the Emperor Titus. The Colosseum was huge. It could seat 50,000 people. It covered around 2.4 hectares of land. It took more than 1 . 1 million tonnes of marble, stone, and bricks to com plete the massive structure. The Roman emperors staged gladiator fights and other forms of enter4 tainment for the Roman people in the Colosseum, including mock sea battles. After four centuries of active use, the magnificent arena fell into neglect. Though two-thirds of the original Colosseum has been destroyed over time, the am phitheatre remains a popu lar tourist destination, as well as an iconic symbol of Rome. Why is the Antonine Plague considered a turni ng point in the history of Rome? I n AD 1 65, a plague called the Antonine plague hit the Roman Empire. The epi dem ic stole the life of a Roman em peror called Lucius Verus. From his fam ily name Antoninus, the epi dem ic got its name Antonine plague. This disease was brought back to the Rome by troops returning from cam paigns in the Near East. In AD 1 78, it caused 2,000 deaths a day in Rome, and by AD 1 80, it had killed thirty per cent of the population. The plague ram paged throughout the Empire from Persia to Spain, and from Britain to Egypt. The plague almost wiped out the Roman army. The disease broke out again after nine years. In brief, the plague may well have created the conditions for the decline of the Roman Empire. Roman soldiers sacked a temple of the god Apollo in Seleucia. The Romans believed that the Plague was Apollo's way of punish ing them for destroying his temple. MILESTONES IN WORLD HISTORY 5 Look! I've gradua ted from Nal anda. What is the significance of the rise of the Gupta Dynasty? T he Gupta Empire existed at the same time as the Roman Empire. It covered about two thirds of modern India, and parts of modern day Paki stan, Nepal, and Bangladesh. The Gupta Empire lasted from about 320 AD to about 550 AD. The dynasty was founded by Sri Gupta. Chan dragupta I, Sam udragupta, and Chan dragupta I I were the most notable rulers of this dynasty. During this time, there was peace and prosperity. Chandragupta I was also known as Chan dragupta the Great, and Maharajadhiraja. Though the Gupta dynasty was established by Sri Gupta, it was Chandragupta I who consolidated and expanded it. 6 Tell MeWhy Writers, artists and were musicians encouraged. It was also an era of extensive i nventions and discoveries in sci ence and technology. Nalanda U niversity, which became the centre for the educa tion, was built during this time. The g reat m athe m atician Aryabhata, the famous poet Kali dasa, and the revered physician Dhanvan tari all lived d u ri ng this era. Therefore, it is not surprising that this period is considered to be the Golden Age of Ancient I ndia. Why is Constantine known as a great Emperor? T he Roman Emperor Constantine, who ruled from 306 to 337 AD, has left his m ark in history as the ruler who united the Western Roman Empire with the Eastern Roman Empire. When Constanti ne came to the throne, the Roman Empire consisted of two separate empires, one in West ern Europe, and the other in Eastern Europe. Constantine was a mighty general who became the sole ruler of both the western and eastern halves, and u nited them into one powerful empi re. In AD 324, Constantine established a new capital of the Roman Empire. He named it Constanti nople, and it became the largest city of its times. Constantine was converted to Christi anity, and became the first Christian em peror of the Roman Em pire. MILESTONES IN WORLD HISTORY 7 INVASION OF THE HUNS Why is the Huns' i nvasion of Europe i mportant? The H uns were a tribe from Central Asia. They were roaming herdsmen who were extremely warlike by nature. The Huns were skilled horsemen who entered Europe from Central Asia in AD 372. As they moved westward, they absorbed Ger man tribal culture. Beware, I'm Hun King Atti la. Horse Trappings of Huns,jrom 4th Century AD The Huns were feared and hated by other tribes, as they had a reputation for cruelty. As they moved towards Europe, Anglo Saxon tribes like the Goths and Visigoth fled before them to Europe. However, the Huns emerged victorious, and conquered large parts of Europe, Persia, and India. The most famous Hun is Attila. He was a great m ilitary leader who led the Huns to several victories over the mighty Roman Empire. The H u n s ' i nvasion of E u rope is a sign ificant event in world history as it m arked the fi rst time E u rope was invaded and conquered by an Asian tribe . Tell MeWhy Why is the treatise titled 'Aryab hatiya' important to world history? A ryabhata was the first in the line of great mathematician-astrono mers from the classical age of Indi Indian and an m athematics astronomy. His most famous works are the Aryabhatiya written when he was 23 years old, and the Arya bhatasiddhanta. Aryabhata was the first to deduce that the Earth is round, and that it rotates on its own axis, creating day and night. He declared that the Moon is dark and shines only because of sunlight. Solar and believed, he eclipses, lunar occurred because of the shadows cast by the Earth and the Moon. In mathematics Aryabhata's con tributions are invaluable. He gave the value of pi, claim ing, for the first time, that it was an approximation. And he was the first mathematician to give what later came to be called the tables of Sines. All these formed a part of his treatise titled Aryab hatiya. It also dealt with other top ics in mathematics, like geometry, square root, cube root, and pro gression. therefore, Aryabhatiya is, undoubtedly one of the most im por tant treatises ever penned.

The Vikings lived in G reenland for almost 500 years, and then disappeared. However, Erik the Red had made Europe aware of the existence of this awesome land, and this has earned him a place in the history of the world. reenland, which is located between the Arctic and the Atlantic Oceans, is the world's largest island. Almost 80 per cent of the land mass is covered by an ice cap and glaciers. Greenland was first settled by a series of nomadic tribal peoples.

T he Normans were a group of people who invaded and conq uered England in 1 066. They came from Northern France. The first Norman king was William the Conqueror who claimed that the earlier ruler of England, Edward, had prom ised him the throne before his death . The Norman Conquest brought an important change in English history for a number of reasons. It linked England more closely with France and the continent of Europe, and created one of the most pow erful monarchies of the times. The Normans brought about great changes in the English language and culture. The feu dal system of France was introduced and strengthened, with the complex institutions that existed in the earlier era. This resulted in the future development of a parliament, and a protection of basic rights, both of which are of supreme importance today. . North Men to Norman In AD 91 1 the French rulers allowed a group of Vikings to settle in Normandy and they were later known as North Men or Normans.

'Angkor Wat was not the original name giv en to the temple when it was built in the 12th century. We have little knowledge of how this temple was referred to during the time of its use. 12 ngkO r Wat is a temple complex in Cambodia. It is the largest religious monument in the world, built by the Khmer King Suryavarman II in the 1 2th century, in honour of the Hindu god Vishnu. Covering an area of roughly 202 hectares, its layout recreates the image of Mount Meru, a legendary place in Hindu mythology that is believed to lie beyond the Himalayas, and be the home of the Gods. Angkor Wat was shifted from H indu to Buddhist use sometime around the late 1 3th century. The temple is used by Buddhists today. Angkor Wat is depicted on Cambodia's national flag, and is Cambodia's national monu ment as well . The temple represents one of mankind's most astonishing architectural achievements.

Wait a minute, my signature is a b i t lengthy. Why was the signing of the Mag na Carta a historic event? The Magna Carta was a docu ment signed by King John of Eng land in 1 21 5. King John of England, raised taxes, arrested people without cause, punished those arrested without a trial, seized land belong ing to the nobles, and was gener ally very unpopular. The nobles finally rebelled against him, and forced him to sign a document called the Magna Carta. The original Magna Carta was written on a parchment made from dried sheepskin. It was written in Latin, and later translated into French. The Magna Carta was issued in English only 300 years later. 14 Tell Me Why The Magna Carta was the first formal document stating that a king had to follow the laws of the land, and it guaranteed the rights of individuals against the wishes of the king. This meant people couldn't be arrested, imprisoned, or have their possessions tak en away except by the law of the land. The Magna Carta guaranteed the civil rights of the individu al. In this respect, it was a historic docu ment, and it remains to this day, a symbol of liberty. What is the significance of the travels of Marco Polo? M arco Polo was one of the most important and famous explorers and writers from Europe. He was born in Venice in 1 254 . In 1 266, Marco's father and uncle left for China to start a trading business, leav ing Marco behind. Marco first ventured to China when he was 1 7, travelling with his father and uncle. The trip took four years. He stayed for 1 7 years, working as an advisor to Kublai Khan and travelling through Asia. Marco returned to Venice, and a few years later he was arrested when Ven ice went to war with Genoa. It was dur ing his jail term that the book 'The Travels of Marco Polo' was written.

Ideas were able to be spread q u icker and farther because of the printing press. The Renaissance was a time of great beauty and art. Art ists l i ke Leonardo da Vinci and Michelangelo created great works of art during this time. It was also a time of creativity. The Renaissance impacted and shaped the future, and the changes that it brought about led to the modern era. MILESTONES IN WORLD HISTORY What was the Black Death? T he Black Death was one of the worst recorded catastro phes in world history. It was a plague that swept through Europe from 1 346 to 1 353, kill ing about 200 million people. The Black Death arrived in Europe by sea in October 1 343, when 1 2 ships docked at the port of Messina after a long journey through the Black Sea, with many of the crew either dead, or sick. People called this disease the Black Death, because death was the inevitable result, and the symptoms of the dis ease included black lumps covering the body. As a result of the Black Death, the population of Europe dropped drastically. 17 Why is the Inca Empire i mportant in world histo ry?

The Incas are famous for having invented terrace farming to grow food more easily on the sharp mountain slopes. They stored their food, and distributed it to all the people in times of drought. Most of the people were farmers, but the I ncas also had specialised professions like weavers who made textiles, and musicians who created new musical instruments. There was an efficient central government, a strong economy, and a well trained army. The I ncas have left a lasting legacy, and many of their traditions live on in the Andes Mountains. Tell MeWhy What is the importance of the printing of the Gutenberg Bible? The invention of the Guten berg printing press is consid ered to be one of the most important inventions of all time. The Gutenberg press wants a proofreader. In 1 455, Gutenberg demon strated the power of the print ing press by selling copies of a two-volume Bible, known as the Gutenberg Bible. Each page of the book had 42 lines. The paper was handmade, and each page contained a watermark. At first, 1 80 copies were made, most of them on paper, although some were printed on vellum, a kind of parchment. The printed Bible proved quite popular, and the stock was quickly sold out. The Gutenberg Bible was the first major book printed using mass produced movable type. This made it significantly cheaper than a handwritten Bible. The Gutenberg Bible signalled the start of the G uten berg Revolution, which led to the Age of the Printed Books. 19 Why is Colu mbus' discovery of the New World one of the most historic events to have ever taken place?

Vasco da Gama, a Portu guese explorer, left Portugal on 8th July, 1 497 to find a sea route to India. He had four ships, and 1 70 men . Earlier, thousands of sailors had lost their lives in attacks and shipwrecks whi le trying to reach India, but that did not deter Vasco da Gama. He sailed around the tip of Africa, and because there was a mon soon wind, he reached I ndia in less than one month. The discovery of this route to India meant that in order to reach Asia, sailors would not have to cross the Mediterrane an or Arabia, both of which were considered to be very dangerous at that time. It allowed the Portuguese to create a colonial empire in Asia, and made it possible for the Portuguese Empire to improve its trade with the East. Most important of all, Vasco da Gama's voyage succeeded in linking Europe and Asia for the first time by an ocean route. It connected the Atlantic and the Indian Oceans, and brought the West and the East closer together. What is the importance of the con quest of the Aztecs by the Span iards? Hernan Cortes' Army T he Aztecs were a fierce tribe of war riors who settled in the Valley of Mexi co in the 1 3th century AD. They fought endless wars with neighbouring tribes until they dominated most of Central America. They established a great civilization, and built spectacular cities. Their capi tal Tenochtitlan lay in the middle of a lake, and became the hub of their vast empire. Invaders led by the Spanish conq uistador Hernan Cortes over threw the Aztecs by force, and cap tured Tenochtitlan in 1 521. They tore down much of the city of Tenochtitlan, and built their own city on the site called Mexico City. The Spanish conquest of the Aztecs destroyed a great civilization. It made Spain a world power, and eventually, led to the creation of Mexico. 22 Mandatory Education was very important to the Aztecs.

What was Copernican helio centrism? C opernican heliocentrism is a very big term for an astro nomical model developed by Nicolaus Copernicus, an astronomer, mathematician, and scientist born in the 15th century. This model changed how we viewed the positioning of the S u n , Earth, and other celestial objects in space. It has the Sun motionless at the centre of the Universe, while the Earth and other planets rotate around it in circular paths. Copernicus was not the first astronomer to suggest the Sun as the centre of the Universe. But, the ideas of earlier astronomers were rejected 24 because of opposition from the Church . However, Copernicus' mod el of the universe was accept ed because his was more accurate. He also had a better formula for the calculation of planet's positions at different times of the year. How many yol ks are there in this bul l's eye? Tell MeWhy Many believe that the theory and ideas put forward by Copernicus heralded the mod ern era in astronomy. Why is the Gregorian calendar an i mportant mi lestone? The G regorian calendar was introduced in 1 582 by Pope Gregory X I I I . I t replaced the Julian calen dar which had been the official calendar of Europe since it was introduced by Julius Cae sar in 46 BC. But the Julian calendar had an error. The length of the Julian year was exactly 365.25 days . However, the actual MILESTONES I N WORLD HISTORY time it takes for the earth to go around the Sun once is closer to 365.2425 days, or about 365 days, 5 hours and 49 mi nutes. This difference is about eleven minutes each year. To correct this, the calendar was moved forward ten days in 1 582, and a new calendar, the G regorian calendar, was intro duced. The Gregorian calendar year differs from the solar year by only 26 seconds. This only adds up to one day's differ ence every 3,323 years. The G regorian calendar is the most widely used calendar in the world today. 25 Wow, that pl anet is a star! Why were Galileo's astronomical observations using a telescope a sci entific breakthrough? G alileo Galilei was an Italian astronomer, physicist, mathemati cian, philosopher, and inventor who lived during the Renaissance period.

However, that did not deter him in any way from pursuing his passion for science. It was while he was blind that he designed a special mechanism for pen dulum clocks. 26 Tell MeWhy ing telescopes of the times. With these telescopes, Galileo was able to observe the skies in ways previously not achieved. They enabled him to carefully observe, analyse, and study the solar system. In 1 61 0 Galileo observed four objects surrounding Jupi ter that behaved unlike stars. These turned out to be Jupi ter's four largest satellite moons. Galileo made many impor tant discoveries which he doc umented in various literary works during his lifetime. Gali leo has been called the 'father of observational astronomy', the 'father of modern physics', and the 'father of science'. What was the impact of Wil liam H arvey's discovery of blood circulation? W illiam Harvey, a 17'h cen tury English physician, was the first person to describe in detail how blood was pumped by the heart, and circulated through out the body. He showed that arteries and veins form a complete circuit, which starts and leads back to MILESTONES IN WORLD H ISTORY the heart. He also described how the heart's regular con tractions drive the flow of blood around the whole body. Harvey was able to make his he discoveries because ignored the medical text books of the time. Instead, he dis sected animals, and made his own observations and the deductions. Harvey's theories of blood circulation drew considerable criticism in the medical com munity at that time but ulti mately, they were proved to be correct, and his contribu tions to modern medicine were hailed. 27 Why is the Taj Mahal a historical landmark?

The Taj took 22 years to complete, and has been hailed as one of the wonders of the world. This monument is made of gleaming white marble. It has a large white dome that is often called an 'onion dome' due to its shape, which is surround ed by four smaller domes. Around 20,000 people worked round the clock for more than two decades to complete this marvel. A thousand elephants were used to transport the con struction materials from different parts of I ndia, and thirty different types of precious and semi pre cious stones were used to adorn it. Tell MeWhy Is it any wonder then that Taj Mahal was designated as a U N ESCO World Heritage Site in 1 983? It is truly poetry captured in stone, and an everlasting tribute to immortal love. How did the contributions of Sir Isaac Newton change the world of science? S ir Isaac Newton was a bril liant English scientist who was born in the 17th century. He came up with numerous theo ries, and contributed ideas to many different fields including physics, mathematics, and philosophy. These theories completely revolutionised the world of sci ence. One of his most famous theories is the law of universal gravitation. It describes the attraction gravitational between different bodies with mass like the Earth and the Moon. Newton was known to have said that this theory of gravita tion was inspired by watching an apple fall from a tree. He also formulated the three laws of motion that relate the forces MILESTONES IN WORLD HISTORY acting on a body to its motion. One of his most famous publi cations is the ' P hilosophiae Naturalis Principia Mathemati ca,' or Mathematical P rinciples of Natural P hilosophy. It proved to be groundbreaking, in that it laid the fou ndation for classical mechanics. Newton was also the first one to build a reflecting tele scope, to study the speed of sound, and to observe spec trum of colours through a p rism. The list of achieve ments of this legendary genius is truly awe inspiring. 29 What is the significance of Samuel Johnson's Dictionary? S amuel Johnson was an English writer and critic, and one of the most famous literary figures of the 1 8th century. H is best-known work is his 'A Dictionary of the English Lan guage'. The dictionary took eight years to complete, and was published on 1 5th April 1 755. It was not the first such dictionary, but was certainly the most important at that time. I n Johnson's lifetime, five further editions were published, and a sixth came out just after his death. John son defined 43,000 words. His dictionary was path breaking in many ways and had a great influ ence on the style of later dictionar ies. Johnson sometimes explained words in his dictionary in a way that showed his opinions too. 30 Not the Only One In 1 755, a new Universal Etymolog ical Didionary compiled by Scott-Bailey was also published. So, Johnson's didionary was not the only one that was published in that year - but it was certainly the most famous one. Tell Me Why Why was the Industrial Revo lution historically important? T he Industrial Revolution is the name given to the enor mous changes that took place in technology, farming, mining, manufacturing and transporta tion from the middle of the 1 8th century through to the middle of the 1 9th century. It began in Great Britain, and spread to Western Europe, North America, and around the world. In the late 1 700s, manu facturing was often done in people's homes, and societies were largely rural. The Industrial Revolution changed all that. The mai n thi ng that happened d u ri n g t h e I n d u strial Revolution was that m achi nes were devel oped that cou ld do many of MILESTONES IN WORLD HISTORY the jobs and tasks that had previously been done by people -or in some cases, ani m als, such as horses.

It was fought between the last ruler of L od hi dynasty, I brah i m Lod h i , and the ruler o f Kabu l , Babur. By 1 526, Babur had cap tured the whole of Punjab, and then he proceeded towards Delhi to meet Ibrahim Lodhi. Ibrahim Lodhi had a much larger army, with formidable war elephants. Babur's army was smaller, but he had guns which he used to scare the elephants. Thanks to Babur's skilful strat egy, his much smaller force was able to defeat Lodhi's MILESTONES IN WORLD HISTORY mighty army. I n addition to heralding the beginning of the Mughal era in Indian history, the victory in the battle made Babur the master of Delhi and Agra, the two political centres of northern India. The treas u res that Babur came to acquire from the royal treas u ry of Delhi made h i m finan cially very strong. Another reason for the impor tance of this battle is the exten sive use of gun powder, matchlocks, and field artillery for the first time in the I ndian sub-continent. All i n all, the first battle of Panipat, pulled curtains on the already crumbling Delhi SUl tanate. The 300 year rule of the Sultanate ended, and a new era in the history of medi eval India began. 33 Why was James Watt's steam engine a milestone in world history? J ames Watt was a Scottish engineer and inventor, and one of the most important con tributors to the Industrial Revo lution. He is best known for making major improvements to the steam engine. The steam engine was actually built for the first time in 1 698 by Thom as Savery, but it was Watt who improved it in the 1 800s, and made it really useful. In Watt's steam engine, steam output and engine speed were con trolled. Watt's steam engine offered a powerful source that could be located almost anywhere. In the late 1 760s, Watt worked with the inventor John Roe buck, and an engineer, Mat thew Boulton. They made steam engines for canals, coal mines, and mills. From the mid 1 800s to the early 1 900s, steam engines powered machines, ran facto ries, trains, and even huge ships. Watt's steam engine domi nated industry and transporta tion for 1 50 years. In 1 698, Thomas Savery, an engineer and inventor, patented a machine that could effectively draw water from flooded mines using stea� pressure. This was the first steam engine. In 1 7 1 2, another English man, Thomas Newcomen, developed an improved version that was used for the next 50 years or so, by mine owners. 34 Tell MeWhy What was the impact of the US Declaration of Independence on the world? The Declaration of I nde pendence was a document declaring the US to be inde pendent of the British Crown. It was signed on July 4th, 1 776, by the representatives of the thirteen colonies. Thomas Jef ferson was the main architect of this document. These colonies had been at war with Britain for over a year, a nd after the document was signed, they became the Unit ed States of America. The Declaration of Independence states that the authority to gov er n belongs to the people, that all people are created equal and have rights to life, liberty, and the pursuit of happiness. MILESTONES IN WORLD HISTORY The Declaration of I nde pendence laid the fou ndation for the United States of Ameri ca, and had great impact on world history. It i nspired the freedom movement in many countries that were under the colonial rule of European countries.

How did the French Revolution change history? T he French Revolution took place from 1 789 t0 1 799. The revolution broke out because of the misrule of the King Louis XVI. By 1 787, the country was nearly bank rupt and the poor people were dying of starvation, while the nobles and the king were living a life of idle lUxury. The French Revolution began on July 1 4th, 1 789 when the people of France stormed the Bastille in Paris - a royal fort that had been converted to a prison. A TaLe to Tell One of the most famous books about the French Revolution is 'A Tale of Two Cities'. It was written by Charles Dickens, and is con sidered one of the greatest literary works of all time. 36 Tell MeWhy The revolution lasted until 1 799, resulting in the abolition of the French royal family, a change in government, further armed con flicts with other countries in Europe, the execution of King Louis XVI and his Queen Marie Antoinette, and the beginning of Napoleon Bonaparte's reign in France. The French Revolution profound ly altered the course of world his tory, and its ideals of Liberty, Equality and Fraternity triggered the decline of monarchies and the rise of republics and liberal democ racies not just in Europe but in oth er continents as well. Why is 'A Vindication of the Rights of Woman' considered to be a milestone in world history? 'A Vindication of the Rights of Woman' is a book written by Mary Wollstonecraft in 1 792. It is a mile stone in that it is one the first books on feminism, which is a movement to uphold the rights of women. Till then, many people believed that here was no need to educate wom en. I n this book, Mary Wollstonecraft pointed out that women's educa tion is of national i mportance because it is women who usually MILESTONES IN WORLD HISTORY educate their children. She says that an educat ed woman can also be companions to their hus bands, rather than just uneducated wives. Wollstonecraft did not see women as simply ornaments to society, or property to be traded in marriage. She argued that women are equal to men in every way, and deserve the same basic rights men have. The ideas in her book were truly revolutionary at the time, and caused tre mendous controversy. 37 Edward Jenner had many different interests. He was a keen natural historian, and carried out research on the habits of the cuckoo bird. His findings on this subject were published in 1 788. Don't worry, i t's j ust sma l l pox vi rus. How did Edward Jenner's dis covery of the smallpox vaccine change the world? For centuries, smallpox was a dreaded disease. It was Edward Jenner who discovered a way to prevent people from catching smallpox. Jenner realised that giving people a mild dose of the disease could protect them from .getting it in a severe form. In 1 796, Jenner conducted his first experiment on a boy called James Phipps, and it was a suc cess. 38 Tell MeWhy Why was the Battle of Water loo a historic event? he Battle of Waterloo is one of the world's most famous battles. It was fought on 1 8th June 1 8 1 5, at Waterloo, in pre sent day Belgium. The overall commanders at Waterloo were two of the greatest generals of all time. They were Britain's D u ke of Wellington who had never lost a battle in 1 2 years of war, and the French Emperor Napole on, who had in his time, crushed every army in Europe except Britain's. But, Waterloo was not just a British victory. The Duke of Wellington would have been hard pressed to win without the timely help of Marshal Blucher's Prus sians. Besides, two-thirds of his own army was made up of allies from the rest of Europe. It was a bloody battle, with heavy causalties on both sides. Waterloo was the battle that finally and decisively end ed the ambition of the French Emperor Napoleon to domi nate Europe. It brought to an end a terrible war that had raged on and off for more than 20 years, and ushered in a hundred years of relative peace, until 1 91 4 . This is how Jenner's vacci nation treatment was born. Jenner's work is regarded as the foundation of immunology. His was the first successful vaccine ever to be developed, and remains the only effective preventive for smallpox. T MILESTONES IN WORLD HISTORY 39 This too was a camera? Hard to bel ieve.

In 1833, slavery was abol ished from the British Empire by an act called The Slavery Abolition Act. Slavery had existed in a number of British colonies, principally in the plantations in the West Indies. This act gave MILESTONES IN WORLD HISTORY all slaves in the British Empire their freedom. The British gov ernment paid compensation to the slave owners. The amount that the plantation owners received, depended on the number of slaves that they had. This act was an important step forward for mankind. It paved the way for the total abolition of slavery all over the world. Slavery was an evil that had degraded humanity for centu ries. Slaves were treated even more harshly than animals, and they had no rights whatso ever. The abolition of slavery was a significant victory for the principle that all men are born equal, and that no man is the personal property of another. 41 Dr. Crawford Long INTRODUCTION OF ANAESTHESIA pain. Surgeons employed all kinds of means, from using opium to alcohol to lessen the pain, without much success.

A pril 1 6th , 1 853 was a histor ic day in India. It was on this day that the first passenger train service was introduced between Bori Bunder, Bom bay, and Thane. The train with fourteen rail way carriages, carrying around 400 guests, left Bori Bunder at 3:30 pm that day. It was drawn by three engines, and covered MILESTONES IN WORLD HISTORY a total distance of 33 km in 57 minutes. Railways were devel oped in India first by the British East India Company, and lat er, by the British Government mainly to transport troops for their wars, and secondly, to transport cotton for export to mills in UK. Since then, the I ndian Rail way has grown to become the largest rail network in Asia today. It is also the world's second largest network oper ated under a single manage ment. Indian Railway has 1 1 5,000 km of track length, and runs 1 2,617 trains to carry over 23 million passengers daily, con necting more than 7, 1 1 2 sta tions. It is indeed amazing to think it all began as a single train service. 43 Use this l fa t-'free' \. rifle. What is the significance of I ndia's first war of i ndependence? I ndia's first war of independence, has great significance, for it marked the first step in India's struggle for freedom from British rule. There was general unrest and discon tent among the Indian people against the policies of the English East India Company. The last straw was the use of ani mal grease on the cartridges of the company's newly acquired rifles. While loading the rifles, the soldiers had to bite off the end of the cartridge, greased with cow or pig fat. Indians against Indians During the first war of independence, many Indian kings were on the side of the British. They fought against the soldiers of the British Army who were their own countrymen. 44 Tell MeWhy This outraged both the Hin du and Muslim soldiers, for it went against their religious teachings. On May 1 Qth 1 857, the Indian soldiers in Meerut protested. Although the upris Ing was quelled by the British, It set the stage for India's Free dom Movement against the British Rule. Why is the book 'On the origin of Species,' a pathbreaking one? O n the Origin of Species, by Charles Darwin is a path breaking book published in 1 859. D arwin changed the way humans viewed themselves, and the world around them, through his ideas on evolution and natural selection. MILESTONES IN WORLD HISTORY Darwin, an English natural ist, put forward the idea that all species of life have evolved over time from common ances tors. During this process, favour able traits become more com mon in successive generations of living things. At the same traits unfavourable ti me become less com mon.

These p l a n ts are look a l i kes. regor Mendel was a 1 9th cen tury monk and brilliant scientist. He was interested in heredity, and through his experi ments, found that certain traits were inherited following specific patterns. Mendel experi mented with peas in his garden , and discov ered that living thi ngs pass traits to the next generation by some thi ng which remains unchanged i n successive generations of an organism. He found that traits could skip a generation - seemi ngly lost traits could appear agai n in another generation - and he called these recessive traits.

Why is the end of the shogun rule i n Japan an important milestone? The shogun was Japan's supreme military leader. He was awarded the title by the emperor. From 1 1 92 through 1 867, Japan was ruled by a series of shoguns. The role of the emperor was ceremonial, simi lar to the position of the Japa nese monarchy after second world war. Also known as the MILESTONES IN WORLD HISTORY Edo period, the shoguns ush ered in a time of internal peace, political stability and economic growth. The shog u ns imposed a strict class system, with the samurai or warriors at the top, followed by farmers, artisans, and merchants. Tokugawa shogunate was the last shogunate in Japan. D u ring its final 30 years in power, the Tokugawa shogu nate had to contend with peas ant uprisings and samurai unrest, as well as with financial problems. In addition, there was the growing threat from Western powers. As a result, many demanded the restora tion of direct imperial rule. The last Shogun Yoshinobu, was overthrown in 1 867. This marked the end of the shogun rule in Japan. 47 Why was the opening of the Suez Canal a historic event? T ------ Win One, Lose One Ferdinand de lesseps was the developer of the Suez Canal which proved to be a grand success. He also dreamt of building a canal across the Isthmus of Panama. Work began in 1 881, but Ferdinand failed to achieve his second dream. 48 he Suez Canal is a man-made canal in Egypt, connecting the Medi terranean Sea to the Red Sea, through the Isthmus of Suez. Earlier, ships sailing between Europe and South Asia had to make a long and dangerous voyage all the way around the tip of Africa. The opening of the Suez Canal in 1 869, changed all that. Ships could now go directly between the Mediterranean and Red Sea through the canal. This 1 93 km long �:eh�2) cut. ...- waterway reduced the sea voyage distance between Europe and South Asia by 7000 km. The Suez is the longest canal in the world without locks- and the safest too. To sum up, the Suez Canal is the shortest sea link between the east and the west, due to its unique geographic location. Its opening gave a tremendous boost to the maritime industry and world trade. How did the invention of the telephone by Alexander Gra ham Bell change the world? A lexander Graham Bell, is best known as the inventor of he telephone in 1 876. He will be remembered for all time as having been the first person to MILESTONES IN WORLD HISTORY design and patent a practical device for transmitti ng the human voice by means of an electric current. The telephone is considered by many to be the most impor tant invention of modern times. It offers a fast, cheap mode of communication. It has reduced the concept of distances when you can contact a per son living thousands of kilometres away i n just a few seconds, the distance does not seem very far. The telephone has i ncreased socialization and interaction between people, and made possible the introduction of the Internet. In fact, if the world is a global village today, it is the tele phone that has played a major role in making it so. 49 Thomas Edison Why is it said that the i nvention of the elec tric bulb lit up the world itself? B efore the invention of the electric bulb, people used candles or oil lamps, which were smoky and messy. Though the invention of the light bulb is associated with Thomas Edi so n , the fact that i s Thomas Edison did not invent it. Several designs for the light bulb had been created before. Sir Joseph Swan of England, and Thomas Edison both i nvented the fi rst electric i ncandescent lamps around the 1 870s. By creating a vacu u m i nside the b u l b , fi ndi ng the right fi lament to use, they were able to ach ieve a l i g ht bulb that l asted for many hours. Edi so n 's i nvention was the most practi cal one. Edison also established a power g rid system, which could generate elec tricity, and deliver it to homes through a network of wires. He subsequently started the Edison Electric L ight Company in 50 Tell M eWhy October of 1 878. F rom then on, there was no looking back, as new and better light ing systems appeared on the market, to light up not just homes, but also offices, roads, and institutions. The list seems never ending. Thanks to Thomas Edison and his electric light bulb, i n every corner of the world, darkness is being banished with the glow of light. Why is television considered a m ixed blessing? Television is a way of send ing and receiving moving i mages and sounds over wires, or through the air, by electrical Impulses. Television's development depended upon previous MILESTONES IN WORLD HISTORY inventions, and more than one person contributed to the development of television, as we know it today. In England, i n the 1 920s, John Bai rd, a Scottish amateur scientist, successfully trans mitted the first TV picture, after years of work. Television has been praised for its ability to transmit visual i mages with accompanying sound to entertain, educate, and to provide a sense of truth. On the other hand, because of television, children have wit nessed war, murder, and vio lence first hand, so television can actually be considered a mixed blessing. In any case, television has sparked revolutions in enter tainment, journalism, and social behaviour that are still ongoing. 51 What was the impact of the Women's Suffrage Movement in New Zealand? The term women's suffrage refers to the right of women to vote and to hold an elected office. Women did not always have the right to vote.

We all have dreams while sleeping, but when we wake up, we generally forget about them. However, in 1 899, Sig mund Freud, a psychoanalyst, believed that our dreams have meanings, and published a book analysing them . Its name was 'The Interpretation of D reams'. It contained some very inter esting theories about our dreams. Always a vivid dream er, Freud had by this time also noticed the i mpact of dreams on his patients. According to Freud, every dream represents a wish fulfil ment or fantasy that is not accessible when one is awake. 56 'The Interpretation of Dreams' is a fascinating text revealing Freud's unique talent as a writ er and ambitious theorist. The book is very important, because it introduced many key concepts that would later become central to the theory of psychoanalysis. WINGS FOR HUMAN Why was the flight at Kitty Hawk a his toric one? Orville Wright M an has always dreamt of being able to fly, but this dream became a reality only because of the Wright Brothers, Orville and Wilbur. They were the first to make a successful flight with humans on board, in an aircraft that was powered by an engine, and was heavier than air. The Wright Brothers believed that their fascination with flight began when their father brought home a toy helicop ter when they were children. Their first flight using an engine was on 1 7th December, 1 903 at Kitty Hawk Island, USA. The plane had a wingspan of 40.3 feet. It was Orville who flew the plane. The flight lasted 1 2 seconds, and the plane flew for 1 20 feet. It was a historic moment when the aircraft landed safely after this maiden flight.

A lbert Einstein was a scien tific genius who was born in 1 879 in Germany. Einstein made many contributions to the field of theoretical physics. He revised Newton's laws of gravity to make them more accurate. We call what he developed the theory of relativity. It is actually two theories. The first is called Special Theory of Rel ativity. This theory states that it is impossible to determine whether or not you are moving unless you can look at another object. The second is the General Theory of Relativity. It is the one which redefined the laws 58 of gravity. The theory explained how time and distance may change due to the 'relative' or different speed of the object and the observer. It broke new ground in the world of science. In 1 921 , Ein stein won the Nobel Prize in Physics for his services to Theoretical Physics. ---- Science has to energise the mass. Tell MeWhy What was the impact of the invention of plastic? P lastic is not the i nvention of one person. The fathers of modern plastics were chem ists Leo Baekeland , Alexan der Parkes, Brandenberger, Roy Plunkett and D aniel Fox. Today, plastic is made in factories using chemicals found in oil and natural gas. It is a very versatile material . It can be coloured by adding dyes. Hot plastic can be poured into moulds in the shapes of toys and other things. It can also be squeezed through holes to make pipes, hoses, and bags. Because it is so light, many parts of aeroplanes and cars are made from plastic. It can MILESTONES IN WORLD HISTORY be made into thin threads and then woven to make material that is used to make clothing such as raincoats and water proof jackets. These plastic materials are called synthetic. Since the appearance of plastic more than 1 50 years ago, modern industry has grown rapidly. Plastics have played a key role in the modern way of life, in the creation of thousands of new articles and technologies. We now use about 20 times more plastic than we did 50 years ago. However, we must remem ber that plastics harm the envi ronment because it is not degradable. Therefore, it is important that we reuse and recycle plastic as much as possible. 59 � What is the significance of the I Rutherford model of atom? l e know that the atom is W th e smallest particle of an ele n,ent still having the same chemical properties of the ele ll'Ient. However, by 1 91 1 , it was d iscovered that the atom was Ihade up of even smaller, or �ubatomic particles called pro tons and electrons. But it was not clear how these protons and electrons were arranged within the atom. It was believed that they were evenly spread out, but this was proved incor rect. It was Ernest Rutherford, who first presented a planetary model of the atom. This put all the protons in the nucleus with the electrons orbiting around the nucleus, like the planets revolve around the Sun. Si r, this is my model of a tom. So simple, isn' t i t?

Ford had been trying to increase his factories' produc tivity for years. To streamline the process, Ford divided the proce dure into 84 steps, and trained each of his workers to do just one step. L ater, he i nstalled moving lines for bits and pieces of the manu facturing process. Finally in December 1 91 3, he introduced the moving-chassis assembly line. Ford's i nnovation reduced the time it took to build a car from more than 1 2 hours, to two hours and 30 minutes. This enabled the company to bri ng out more cars faster. It also cut down costs, so the cars could be sold cheaper. 61 What was the i mpact of World War I on the world? W orld War I was a global war fought in Europe. It began in 1 91 4 and lasted for four years till 1 9 1 8. It was fought between the Allied Powers and the Central Powers. The main members of the Allied Powers were France, Russia, and Britain. The United States also fought on the side of the Allies after 1 91 7. The mai n members of the Central Powers were Ger many, Austria- H u ngary, the Ottoman Empi re, and Bul garia. There were many reasons for the war, but the immediate cause was the assassination of Austria's Archduke Ferdi62 nand by a Serbian youth Gavri10 Princip. More than 65 million soldiers fought in the war in the battle fields of Europe. The Allies eventually won, but the price was heavy indeed. It is estimated that by the time the war was over, over 9 million soldiers had been killed, and another 21 million wound ed. The member countries of the Central Powers were forced to sign armistice agreements one by one, and Germany was severely punished under the Treaty of Versailles.

The first revolution was in Febru ary, and the second in October of 1 91 7. Prior to the revolution, the Russian monarchy had become pro gressively weaker, and increasingly insensitive to the hardships of the people. The emperor, Czar Nicolas I I , used extremely severe measures to put down resistance movements with little effect. Vladimir Leni n , the leader and motivating force behind the revolu tion, rose to prominence as the most powerful figure in Russia. Though the revolution was successful in overthrowing the monarchy, the new government, led by Vladimir Lenin, would solidify its power only after five years of civil war, which ended in 1 922. After the Russian Revolution, Rus sia withdrew from World War I . The Tell MeWh� revol ution had far reaching consequences.

Mussolini became the dictator of Italy, and at first, many Italians were happy with Mussolini's rise to power. Order was restored, and the Fascists began pro grammes of public works. Mussolini helped landowners and industry leaders, and con vinced the common people that the coun try was finally being run efficiently. However, fascism became unpopular before long when parties that opposed it were outlawed. Workers were forbidden to go on strike.

MILESTONES IN WORLD H ISTORY credited with the Big Bang theory of how the U niverse began. Today, most astronomers agree with this theory that the Universe began in a Big Bang, about 1 3.8 billion years ago. At that time, the entire Universe was i nside a bub ble that was thousands of times smaller than a pinhead. It was hotter and denser than anything we can i magine. Then, it suddenly exploded. The U niverse that we know was born. Time, space, and matter all began with the Big Bang. In a fraction of a second, the U niverse grew from smaller than a single atom , to big ger than a galaxy. And it kept on growing at a fantastic rate. It is still expanding today.

So, he made it his goal to find anti bacterial substances and he succeeded, with the discovery of penicillin. Hooray . . Hooray . . . I t's a 'mouldy' hol iday. Why was the discovery of penicil lin a giant leap forward in medi cine? P enicillin is a common antibiotic that is used to treat infections today. It was discovered quite accidentally by the Scottish bacteriologist Alex ander Fleming, in 1 928. He had gone on a vacation, and when he came back he found that a green mould called Penicillium notatum had contaminated the petri dishes i n his lab. I n addition, this mould was killing some of the bac teria he had been growing. Fleming called his discovery 'mould juice'. Later, the name pen icilli n was adopted. After much research and experi mentation, an i njectable, mass-produced form of penicillin was ready by 1 942. That was just i n time to help soldiers wounded in World War I I.

World War II was the world's most devastating war ever, directly involving more than 1 00 million people from over 30 countries. Lasting six years, it began on 1 st Sep tember 1 939, with the i nvasion of Poland by Germany. It was a war between two groups of countries - the Allies and the Axis.

The first computer chips had several thou sand transistors on each chip to perform calculations. 80 How has the i nvention of the tran sistor changed the way we live? A transistor is an electronic component that can be used as an amplifier, or as a switch. The transistor revolutionised the field of electronics, and paved the way for smaller and cheaper radios, calculators, and comput ers, among other things. Three physicists were credited with the invention of the transis tor in 1 948. They were Walter Brattain, John Bardeen and Wil liam Shockley. The first transistor was about the size of our palm, and was made from Germanium. Since then, transistors have become smaller and smaller. Introduced in 1 952, Shockley's bipolar junction transistor, which was made from a solid piece of semiconductor material, dominatTell MeWhy ed the industry for the next 30 years. By 1 954,Texas I nstru ments developed the first transistor made from silicon. Today in electronic devices we use comput er chip, also called chip, integrated circuit or small wafer of semicon ductor material embed ded with integrated circuitry. Chips com prise the processing and memory units of modern digital computers. As transistor compo nents have shrunk, the number of chips have doubled about every 1 8 months, from a few thousand to more than one billion. What is the significance of January 26th, 1 950?

In the early 1 950s, scientists had learned a lot about genetics, but they still didn't understand the structure of the DNA molecule. James Watson and Francis Crick discovered the structure of the DNA in 1 953. They were able to put together an accu rate model of the structure. Why was Sputnik 1 a landmark in space exploration? S putnik 1 was the first man made satellite to be launched into orbit. It was launched by the Soviet U nion on October 4th 1 957. The tiny spacecraft orbited Earth once every 90 minutes. The satellite was the size of a basketball and it travelled at about 29,000 kilometres per hour.

Mob: 9881477305 Tell MeWhy Question sent by: Aditi Gupta, on e-mail. Send us your questions E mail: [email protected] Why is plaster of Paris so called? Plaster of Paris, or simply plaster, is the common name for calcium sulphate hemihydrate. It is made by heating the mineral gypsum. There is an interesting story behind its curious name. In 1 666, a fire that raged across the city of London destroyed many buildings. Keeping this catastro phe in mind, the King of France ordered that all walls made of wood in Paris be immediately covered with plaster, as a protection against such fires. Paris had a lot of gypsum deposits at that time, and the king's order resulted in the large-scale mining of the mineral. Thus, the city of Paris became the cen tre of plaster production, and hence the material came to be known as plaster of Paris.
