Inilah CHARLES DARWIN 1809-1882

The same is true with the birth of Abraham Lincoln, February 12, 1809 in Shrewsbury, England. Charles Darwin was the inventor of the theory of organic evolution in the sense that natural selection is at the age of sixteen entered the University of Edinburgh to study medicine, but both the medical and anatomical science that makes it deems bored. Soon he moved to Cambridge to study elements of office administration. Even so, hunt and ride horses in Cambridge digemarinya far more than the learning of science. And even so, she's still able to attract the attention of one of the Grand Masters are encouraged to participate in a voyage on board HMS investigation Beagle as a naturalist. At first her father objected to this appointment. She thought the trip like that is just an excuse just reluctant to make Darwin a serious job. Fortunately, later the father could be persuaded, and bless the journey which ultimately proved to be a journey of the most valuable in the history of European science.
Darwin began to go sailing on board the Beagle in 1831. At that time he was only twenty-two years. Within five years of shipping, ship Beagle sailed the world, scour the coast of South America in an exciting pace, explore the Galapagos Islands a quiet secluded, mengambah islands in the Pacific, the Ocean Indonesia and the southern Atlantic Ocean. In perkelanaan it, Darwin witnessed many miracles of nature, visiting primitive tribes, found a large number of fossils, examine the various kinds of plants and animal species. Furthermore, he made many notes about anything that passes in front of her eyes. These records are the basic ingredient for almost all of his work in the future. From these records are just ideas, and events and experiences to be supporting his theories.
Darwin returned to his country in 1836 and twenty years afterwards he published a line of books, which made him a famous biologist in the UK. Commencing from the year 1837 Darwin convinced that animals and plants are not fixed, but changes in the course of geological history. At that time he was not aware of what causes the occurrence of evolution. In 1838 he read an essay "Concerning the principles of population" Thomas Malthus. Malthus's book is menyuguhkannya the facts that led more convinced of natural selection through competition to sustain life. Even after Darwin succeeded in formulating the principles of natural selection, he was in no hurry to print and publish it. He was conscious, his theory would invite challenges. Therefore, he takes a long time carefully preparing the evidence and put the horses to maintain the hypothesis if there are attacks.
The outline of the theory written in 1842 and in 1844 he began compiling his book at length. In June 1858, when Darwin was still being added to increase and improve the book by size, he received a manuscript from Alfred Russel Wallace (a British naturalist who was located in the East) outlined his own theory of evolution. In each of the basic problems, along with Wallace's theory Darwin's theory! Wallace was developing his theory is really standing on his own mind and send the manuscript to Darwin's writings to ask for opinions and commentary from prominent scientists signed it before printing. The situation was bad because it is easy to grow so the fight is not desired to scramble priorities. Way out, both Wallace's script and the outlines of Darwin's theory simultaneously addressed by a scientific body in the next month.
Simply amazing, preposing this problem is not so neglected people. Darwin's book The Origin of Species published in the following year, causing much controversy. It is in fact probably never have published a book of science that is so widespread and so so so warm conversation material, both within the scientists or laymen, such as occurs in the book On the Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Strugle for Life. They put forward an argument remain exciting in 1871 when Darwin published The Descent of Man, and Selection in Relation to Sex. This book, put forward the idea that human beings originated from a type of monkey, adding the thrill of debate opinions.
Darwin himself did not take part in debates in public about the theories say. It could be because health is so because after perkelanaannya parrjang with the ship Beagle (most likely due to fever, due to insect bites Chaga disease in Latin America). And it could be because she felt quite have such a staunch supporter of Thomas H. Huxley a debate champion and defender of Darwin's theory, most scientists agree the basics of Darwin's theory of truth when the relevant niati 1882.
Actually - if you want to talk to a real or not real - not the first inventor of Darwin's theory of evolution. Some people have menyuarakannya before him, including the French naturalist Jean Lamarek and Darwin's own grandfather, Erasmus Darwin.
However, their hypothesis is never accepted by the scientific world because it was unable to give assurance of how and in what way evolution occurs. Darwin's greatest contribution is its ability not only present the mechanism of natural selection that resulted in the occurrence of natural evolution, but he is also capable of presenting a lot of evidence to support the hypothesis.
Worthy of note, Darwin's theory was formulated without any backrest genetic theory or in fact he did not know anything about that knowledge. In Darwin's time, no one would understand how a particular matter of the next generation. Although Gregor Mendel's laws were completed descendants in those years coincided with the time Darwin wrote and published his book which makes history, Mendel's work that support Darwin's theory is so perfect, almost entirely ignored Mendel people until 1900, when Darwin's theory is so well-established and steady. So, our modern understanding about evolution - which is a combination of genetic science to the law of natural selection descent - more complete than Darwin's theories proffered.
Darwin's influence on human thought in sekah. In terms of pure science, of course, he was committing a revolutionary all aspects of biology. Natural selection really have a very broad principles and fundamental, and various attempts had been made its application in various areas such as anthropology, sociology, political science and economics.
Perhaps even more important influence on Darwin's thinking in terms of religion rather than on science or sociology. In Darwin's time and for years afterward, many loyal followers of Christianity believe that accepting Darwin's theory mean lower degree of confidence in religion. Their concern is probably unfounded because although clearly many other factors that be because the dilution of religious belief. (Darwin himself became a secular).
Even on the basis of secular, Darwinian theory lead to major changes in the way people think about happenings in their world they (the human race it seems) as a whole no longer occupy a central position in the natural scheme of things, as was their nature akukan. Now we should see ourselves as one part only of the many creatures and we acknowledge the possibility that once a date will be shifted. As a result of the investigation results of Darwin, the view of Heraclitus who said, "Nothing is permanent except change" becomes more widely accepted. Successful theory of evolution as a general explanation of the origin of humans have more solidified confidence in the ability of science to answer any questions the physical world (although not all human problems and human). Glossary Darwin, "The strong defeating the weak" and "Struggle for life" had become a part of our dictionary.
Indeed, Darwin's theory will be explained as well though such as Darwin had never lived in the world. Moreover, the measure of what has been produced by Wallace, it is quite contain the truth, more than any particulars contained in this book list. However, it is Darwin's writings that has revolutionized biology and antropolgi and it was he who changed our view on the position of humans in the world.

Inilah Constantine the Great 250-337

This figure first Roman emperor who embraced Christian Religion. Through convert it and various ways by which this development, he held prominent role in this change of religion Christian Religion which are pursued and threatened with punishment became the dominant religion in Europe.
Constantine was born about the year 280 in the city Naissus (now named Nis) in the country which is now Yugoslavia. His father was a high-ranking officers, and Constantine spent his youth in Nicomedia, where the court of Emperor Diocletian located.
Diocletian ascended the throne in 305 and father of Constantine - Constantius - became ruler in the western part of the Roman Empire. When Constantius died in the following year, Constantine declared emperor by his soldiers. However, other generals at odds with each other about this coronation and civil war was inevitable. This new war ended in 312 when Constantine defeated by opponents who still survive - Maxentius - in a battle at Milvian bridge near the city of Rome.
Not certain when Constantine entered Christian Religion. The stories commonly heard saying, at times before the battle at the bridge Milvian, Constantine saw a cross burning in the sky and says "By this sign you will be able to conquer." No matter when he entered the Christians, Constantine did much for the progress of Christian Religion. Pemulanya One step is to make the Act Milan. With this law is The Christian religion is legal and tolerated religion. The law also allows the return of Church property that was seized during the chase and ransacked in the past. Also declared Sunday as a day of worship.
Milan Law is not based solely by the attitude of religious tolerance. Instead, the government Constantine can be considered as a sign bermulanya oppression against the Jews who continued to take place in Christian Europe in the coming centuries.
Constantine was never made Christianity as the official state religion. However, through legislation and political steps he is clearly driving the development of this religion. In his reign it was obvious, anyone who entered the open door of Christianity means to him in terms of ease up a career ladder in administration. And decisions issued by Constantine also provides immunity and privileges of the church. Similarly, he built the famous churches in the world - such as the birth of Jesus Church in Bethlehem and the Tomb of Jesus church in Darussalam. All of this church was built at the time of Constantine.
The role of the Roman Emperor Constantine as a Christian religion by itself make him eligible list in the order listed in this book. However, some actions contain the effects of distant futures. For example, he is renovating and expanding the city of Byzantium, and replaced with the name of Constantinople (now Istanbul) is one of the largest cities in the world and still be the capital of the Byzantine Empire until 1453 and several centuries later became the capital of the Ottoman Empire.
Constantine also played an important role in the internal history of the church. Involve themselves in disputes between the followers of Arius and Athonius (two Christian theologians who propose different doctrine), Constantine called the Council meeting Nicola (at 325), the first church council proceedings. Council where Constantine took part actively, to resolve disputes with the accepted doctrine of the Nicene, which later became the orthodox doctrine of the church.
Another important thing is its role in relation to the preparation of civil regulations. Constantine make the legislation governing companies down through the generations (like Joqal, baker). The issuance of the decree which it also set the "colony" (peasant class) are forbidden to leave the ground garapannya. In the modern sense of this decree means to change the "colony" (sharecroppers), a slave, bound with the soil. This decree and other rules are the foundation stone of the whole social structure in medieval Europe.
Constatine not baptized until he lay in bed in a state of dying, though obviously he had entered The Christian long before that. However, concurrent with it is also true that the soul kenasraniannya faded completely. Although the size of the time, he was so violent and cruel. This attitude is not directed to his opponents only. The causes are not clear, he punishes his wife and son in 326.
Can be questioned, the acceptance of The Christian Constantine previously not alter the course of history, but only endorse things that can not be inevitable. In addition, although Biocletian Emperor (reigned from 284-305) has done a great gencetan of Christian Religion, his efforts to make religion that does not work because it was Christian Religion is much more powerful than the power that will be hit even by acts of cruel however. Tarolah people regard the failure of an experiment gone Biocletian quell Religion Christianity and religion could win even without interfering Constantine altogether. Supposition and speculation like that is interesting, but not convincing and uncertain. It's hard to imagine what would happen without Constantine. It is very clear, with encouragement, Religion Christianity is widespread both in number and size following regional influence. From a small group that does not mean only in a period of one century become an established religion and have a great influence in the world.
Evidently so, Constantine is a pivot figures in European history. Place in the order list is higher than the figures of Alexander the Great, Napoleon and Hitler because the effect of a long range.

Inilah NICCOLO MACHIAVELLI 1469-1527

Italian political philosopher, Niccolo Machiavelli, famous for the frank advice that a ruler who wanted to remain in power and strengthen his power must use guile, cunning and deceit, coupled with the use of cruel use of force.

Condemned many people as the bastard did not bennoral, revered by others as genuine realist who dared to expose to the world as it is, Machiavelli was one of the few authors whose work is so close to the study of both philosophers and politicians.

Machiavelli was born in 1469 in Florence, Italy. His father, a lawyer, considered a leading member of the family, but not so located.

During Machiavelli's lifetime - at the peak-peak Renaissance Italy - Italy is divided in small countries, in contrast to a united country such as France, Spain or England. Because it is not surprising that in his time Italy was militarily weak but brilliant in terms of culture.

At the time the young Machiavelli, Florence was ruled by the famous Medici ruler, Lorenzo is commendable. But Lorenzo died in 1492, and several years later expelled the Medici rulers of Florence, Florence became a republic (Florentine Republic) and in 1498, Machiavelli who was twenty-nine years obtained a higher rank in the civil administration Florence. Over the past fourteen years after that he served the Florentine Republic and engage in various diplomatic missions on his behalf, to travel to France, Germany, and Italy in the country.

In 1512, the Florentine Republic was overthrown and the Medici rulers re-hold the reins of power, Machiavelli was dismissed from his position, and the following year he was arrested for alleged involvement in a plot against the Medici rulers. He was tortured but survived declared not guilty and was released in that year. After that he retired and lived on a small farm in San Casciano not far from Florence.

Over the past fourteen years after that, he wrote several books, two of the most famous is The Prince, (The Prince) was written in 1513, and The Discourses upon the First Ten Books of Titus Livius (Discussion of the first ten books of Titus Livius). Among other works are The art of war (the art of war), A History of Florence (Florentine history) and La Mandragola (a good drama, sometimes people are still staged.) But essentially the work of the famous is The Prince (The Prince), perhaps the most brilliant ever written and is most easily read of all philosophical writings. Machiavelli married and had six children. He died in 1527 at the age of fifty-eight.

The Prince may be considered the most important practical advice for one to the state. The basic mind this book is, for a success, a prince should ignore moral considerations entirely and rely on all, things on the strength and cunning. Machiavelli emphasized above all else the most important is a country must be well armed. He argues the only armies that are required from citizens themselves who can be trusted; countries that rely on mercenaries or soldiers of other countries is weak and dangerous.

Machiavelli advises the Prince for to support the population, because if not, he does not have a source of trouble. Of course, Machiavelli understood that sometimes a new ruler, to strengthen his power, must do something to secure his power, was forced to do unpleasant citizens. He suggested, though so to win something the state, the conqueror must arrange cruelty step at a time so no need they experience every day leeway should be given little by little so that they can feel happy. "

To achieve success, a prince must be surrounded by ministers who are able and faithful: Machiavelli's Prince warned to stay away from sycophants and asked what opinion is worth doing.

In chapter 17 of The Prince, Machiavelli discuss whether a prince that's better be hated or loved.

Machiavelli writes: "... The answer is that people should be feared and loved at the same time. ... But safer feared than loved, if we must choose one. The reason, love is bound by obligations that makes a person selfish, and bond It will end when dealing with their interests. ... But the fear is driven by fear punishment, never missed ... "

Chapter 18, entitled "The way how a prince holding the belief." Here Machiavelli said: "... a ruler who must be careful not to hold beliefs if the work was contrary to its interests ..." He added, "Since there is no official basis blaming a prince who apologized because he did not fulfill his promise," because "... man it was so simple and easy to comply with the requirements needed at the time, and that one who cheats will always find people who allow themselves deceived. " As a natural result of that view, Machiavelli advises the Prince to be constantly vigilant against the promises of others.

The Prince (The Prince) is often dubbed the "user's guide to the dictator." Machiavelli's career and various writings indicate that in general he tends to the republican form of government than dictatorship. But he was anxious and worried about the political and military weakness of Italy, and longs for a Prince of a powerful country that can manage and drive foreign troops destructive and despised his country. Interesting to note, though a Prince Machiavelli advocated for such actions cruel and cynical, he is himself an idealist and a patriot, and not so able to practice it himself what he is proposing.

Few political philosophers such diganyang acutely experienced by Machiavelli. For years, he cursed like a derivative of the devil, and his name is used as a synonym for duplicity and cunning. (Not infrequently, the bitterest curse to come from those who actually practice the teachings of Machiavelli, a hypocrisy which may principally be approved also by Machiavelli)!

These criticisms are thrown into the face of Machiavelli than moral grounds is not, of course, shows that he has no effect at all. A more direct criticism is alleged objection that his idea was not specifically out of his own head. Not original! It's a bit much have a point. Machiavelli repeatedly asked that he did not propose anything new, but merely shows the techniques that have been implemented by the Princes earlier with great success. Reality show Machiavelli unrelenting while describing his proposal to sample the greatness-greatness that never happened in the days past, or from events in Italy are somewhat renewal. Cesare Borgia (which is being touted by Machiavelli in The Prince) is not to learn the tactics of Machiavelli, on the contrary, Machiavelli who learned from him.

Although Benito Mussolini was one of the few political leaders who had publicly praised Machiavelli, because it is no doubt a large number of prominent political figures have never read The Prince carefully. It is said that Napoleon always sleep on the pillow tucked beneath her book The Prince, as well as they say carried out by Hitler and Stalin. However, it is not apparent that Machiavelli is more commonly used tactic in modern politics than in the period before The Prince was published. This is the main reason why Machiavelli is not placed higher than the place now in this book.

However, if effect, Machiavelli's thought in political practice is not so clear, its influence in political theory does not need to be debated. Previous writers such as Plato and St. Augustine, has linked politics with ethics and theology. Machiavelli discussed the history and politics entirely in terms of human and ignore moral considerations. The central problem, he says, is not how people should behave, rather than who should be in power, but how real people can gain power. Political theory is discussed today in a way more realistic than ever before without minimize the significance of the influence of Machiavelli. This person can properly be considered one of the important founders of modern political thinkers.

Inilah ABRAHAM LINCOLN 1809-1865

ABRAHAM LINCOLN 1809-1865

President of the United States into the 16th, Abraham Lincoln, one of the most famous and impressive political figure who once owned the United States - or any country as well. Well, if it does, because what he is not included in the list of the main sequence? Do not release 3.5 million bondsman a masterpiece?
Indeed so. But if we look back, will be seen that strength around the world are struggling irresistible by any force to eliminate all forms of slavery. Many countries had abolished the system of slavery even before Lincoln's reign, and within fifty-five years after his death, most countries do so. The most can be appreciated from the work of Lincoln is to accelerate the process in a country, the United States.
ABRAHAM LINCOLN 1809-1865
However, the work of Lincoln's greatest service is to maintain the unity of the United States faced attempt secession states south of the country. For this act alone he is entitled to be included in the list order this book.
However, through Lincoln's election was the one who so because the separation of the states south of it. And certainly not the North would also failed to win a civil war if people other than Lincoln became president. And above all, the North opened the battle with the superior of capital, looking from the corner of the population and also greater in the industry.
Even if the North did not win the war, on the whole course of history will not experience major changes. The link language, religion, culture and trade between North and South is so tightly they would unite also. If the split lasted for twenty years, or put, fifty years, it was only a minor event in world history. (Worthy of note that even without the South, the United States now remains the fourth largest populated country in the world, and will remain the most leading industrial countries).
Does this mean that Lincoln did not figure at all important? Absolutely not. His career has profound influence on millions of people in one generation. However, he has not been equal importance as Mahavira whose influence continued for centuries.

Inilah Penemu Listrik THOMAS EDISON 1847-1931

Versatile inventor Thomas Alva Edison was born in 1847 in Milan, Ohio, United States. Just three years he received formal education, after it kicked out of school because the teacher thought the child was incredible stupid.
THOMAS EDISON 1847-1931
 His first creation, electronic voice recorder dibikinnya when he was twenty one years. Her work did not sell. After that he earned expectation fabrication equipment can be sold in the market, shortly after he managed to make an electronic voice recorder, he discovered and perfected telegraph machines that automatically print the letter, which sold for 40,000 dollars, a huge amount at that time. After that, as he queued to find new work and in a short time Edison was not only famous but also the rich. Perhaps, the most original invention is a patented machine LPs in 1877. However, more famous in the world than it is the development of a practical incandescent light bulb in 1879.
Edison was not the first to create a system of electric lighting. A few years earlier bersinarkan light electric current has been used for street lighting in Paris. However, the ball follows Edison incandescent electric power distribution system which enables the development of practical electric lighting for the home. In 1882, his company began producing electricity for homes in New York, and in a short time had spread throughout the world.
With the establishment of the first electricity for lighting homes, Edison is already laying the groundwork for the development of big industry. The use of electric power is not just for lighting but for all aspects of their household needs, ranging from televisions to washing machines. Furthermore, the use of electricity through the distribution networks established Edison in itself encourage the use of electricity for the industrial sector.
Edison also gave large donations made remarkable progress film cameras and projectors. He made important improvements pertilponan (carbon transmitter increase the clarity of hearing), improvements in the field telegraph, and typewriter. Among other findings, among others, dictation machines, coffee machines and battery-driven storage. Arguably, Edison designed more than 1000 inventions, a number that really does not make sense.
One reason for its productivity is very surprising because in the beginning of his career he built a laboratory investigation in Menlo Park, New Jersey. That's where he called for the group which enabled makers to help him. This is the embryo of a laboratory investigation that later imitated by so many industries. Edison beginner modern laboratories, a fully equipped central inquiry where so many people working together is a team, is also the result of his work is important, though, of course, something she could not patented.
Edison was not only an inventor, he also engaged in fabrication and organizing various industrial companies. The most important of which eventually transformed into the General Electric Company.
Although the traits he's not a pure scientist, Edison make a scientific discovery. In 1882 he found that in a state of near vacuum, electric current can flow between the two wires are not touching each other. This phenomenon - called Edison's invention - not just have an important theoretical purpose, but also have practical use meaningful sense. This leads to the development of vacuum tubes and laying the basis of the electronics industry.
Almost all his lifetime, Edison suffered from weak hearing. But, even so, he is more than able to overcome it with hard work are amazing. Edison married twice (his first wife died young), has three children from each wife. He died in 1931 in West Orange, New Jersey.
There was no disagreement about the talent Edison. Everyone agreed that he was the inventor of the genius who ever lived. Rows of his findings are very helpful considered appalling and raise a knee chills, although perhaps only partly developed by another person within thirty years. However, if we consider his personal discoveries, would seem to us that none of it has a decisive significance. For example, incandescent ball, although widely used, is not an irreplaceable items in the modern world. The fact is, lighting that comes from the radiation and the outgoing scattered in the form of light, which works on the basis of scientific principles are entirely different, also used by people at large, and in our daily lives does not make any difference if we do not use incandescent light bulbs altogether. Indeed, prior to use electric lighting, candles, oil lamps, and gas lamps are generally regarded as satisfactory levels of illumination.
LPs tool is a clever invention, but nobody thought the device was able to change our daily lives as well as the role that served the radio, television or telephone. Furthermore, in recent years, has to be created a voice recording device with an entirely different method, such as magnetic tape cassettes. And if there is no machine record, it did not feel anything. Many of Edison's patents relating to the improvement of tools, have actually been found by other people first, even in a form that can be utilized. These improvements - although much help - can not be regarded as an important meaning in the series of historical movements in general.
But, although none of Edison's inventions have an appalling significance, useful also to remember that he did not just create a single tool, but more than a thousand. On the basis of these considerations I put Edison higher than such famous inventor Guglielmo Marconi and Alexander Graham Bell.

Inilah Wilhelm Conrad Rontgen tools that created the famous X-ray

Wilhelm Conrad Rontgen
November 8, 1895 X-ray again to make the experiment with the "cathode rays." Cathode rays consist of electron flow. Diprodusir flow by using high voltage between electrodes placed at each end of the glass tube where the air is almost entirely emptied. Cathode rays themselves are not specific and has stopped seeping by several centimeters of air. In this incident X-rays has been completely shut down his cathode ray tube with thick black paper, so that even electric light lit, no light can be seen from the tube. However, when X-rays turned on the electric current in the cathode ray tube, he was surprised to see that the light began to anneal on the screen that is located near the bench as stimulated by light. He put out the tube and screen (which is wrapped by a barium platino cyanide) stop light anneal. Because the cathode ray tube is fully closed, X-rays immediately aware that something invisible form of radiation that must come from the tube when the electric light turned on. Because this is a mysterious thing, he calls it visible radiation "X-rays" The "X" is a common mathematical symbol for something unknown.

Tempted by an accidental discovery, the X-ray investigations of other aside and concentrate on a review of things contained in the "X-rays" After several weeks of hard work, he found other evidence such as this: (1) X-ray beam can make various chemical objects in addition to "barium platinocyanide." (2) X-rays can break through the various objects that do not penetrate the normal light. Special X-rays found that X rays can penetrate the meat directly but stopped on his bones. By putting his hand between the cathode ray tube and the glowing screen, X-rays can see on the screen image of hand bones. (3) X-ray running vertically; not like electrically charged particles, X-ray did not terbelokkan by magnetic fields.

X-rays give a big contribution and advancement of world dentistry

Month December 1895 Rontgen wrote his first paper on X-rays Report in a short time arouse attention and uproar. Within a few months, hundreds of scientists to investigate X-rays, and within a year about 1000 papers published about it! One of the scientists who rely directly investigation of X-ray findings is Antoine Henri Becquerel. This man, although its main purpose to investigate X-rays, it is important to find the phenomenon of radioactivity.

In general, X-ray work when high energy electrons on target. X-rays themselves do not contain electrons, but electron magnetic waves. Therefore, he is basically similar to the radiation that can be seen the eye (ie light waves), except X-ray wavelengths much shorter.

The use of X-rays of the best known - of course - in the field of medical and dental diagnosis. Another use is in the field of radiotherapy, in which X-rays used to destroy malignant tumors or prevent their growth.

X-rays are also widely used in various industrial purposes. For example, can be used for measuring thickness of object or find something hidden damage. X-rays are also useful in many areas of scientific investigation, ranging from biology to astronomy. In particular, X-ray scientists presenting large amounts of information relating to atomic and molecular structure.

Nevertheless, one should not exaggerate the significance of X-ray rate. It is true, the use of X-ray brings many benefits, but one can not say he has revolutionized the whole of our technology, like Faraday's discovery of electro-magnetic proof. Similarly, one can not say the discovery of X-ray is truly a fundamental importance in the theory of science. Ultraviolet light (a wavelength shorter than visible light by the eye) has been known nearly a century earlier. The existence of X-rays - which have similarities with ultraviolet waves, but still much shorter wavelength - still within the framework of classical physics. Above all, I think the significance of X-ray proper place under the discovery Becquerel have more fundamental significance.

X-rays do not have children, so he and his wife raised the child was a girl. In 1901 R�ntgen received the Nobel Prize for physics, which for the first time be given to the field. He died in Munich, Germany in 1923.

Inilah Sejarah Indonesia (1945-1949)

Kembalinya Belanda bersama Sekutu

Sesuai dengan perjanjian Wina pada tahun 1942, bahwa negara-negara sekutu bersepakat untuk mengembalikan wilayah-wilayah yang kini diduduki Jepang pada pemilik koloninya masing-masing bila Jepang berhasil diusir dari daerah pendudukannya.
Menjelang akhir perang, tahun 1945, sebagian wilayah Indonesia telah dikuasai oleh tentara sekutu. Satuan tentara Australia telah mendaratkan pasukannya di Makasar dan Banjarmasin, sedangkan Balikpapan telah diduduki oleh Australia sebelum Jepang menyatakan menyerah kalah. Sementara Pulau Morotai dan Irian Barat bersama-sama dikuasai oleh satuan tentara Australia dan Amerika Serikat di bawah pimpinan Jenderal Douglas MacArthur, Panglima Komando Kawasan Asia Barat Daya (South West Pacific Area Command/SWPAC).
Setelah perang usai, tentara Australia bertanggung jawab terhadap Kalimantan dan Indonesia bagian Timur, Amerika Serikat menguasai Filipina dan tentara Inggris dalam bentuk komando SEAC (South East Asia Command) bertanggung jawab atas India, Burma, Srilanka, Malaya, Sumatra, Jawa dan Indocina. SEAC dengan panglima Lord Mountbatten sebagai Komando Tertinggi Sekutu di Asia TenggaraJepang dan mengurus pengembalian tawanan perang dan tawanan warga sipil sekutu (Recovered Allied Prisoners of War and Internees/RAPWI). bertugas melucuti bala tentera

Mendaratnya Belanda diwakili NICA

Berdasarkan Civil Affairs Agreement, pada 23 Agustus 1945 Inggris bersama tentara Belanda mendarat di Sabang, Aceh. 15 September 1945, tentara Inggris selaku wakil Sekutu tiba di Jakarta, dengan didampingi Dr. Charles van der Plas, wakil Belanda pada Sekutu. Kehadiran tentara Sekutu ini, diboncengi NICA (Netherland Indies Civil Administration - pemerintahan sipil Hindia Belanda) yang dipimpin oleh Dr. Hubertus J van Mook, ia dipersiapkan untuk membuka perundingan atas dasar pidato siaran radio Ratu Wilhelmina tahun 1942 (statkundige concepti atau konsepsi kenegaraan), tetapi ia mengumumkan bahwa ia tidak akan berbicara dengan Soekarno yang dianggapnya telah bekerja sama dengan Jepang. Pidato Ratu Wilhemina itu menegaskan bahwa di kemudian hari akan dibentuk sebuah persemakmuran yang di antara anggotanya ialah Kerajaan Belanda dan Hindia Belanda, di bawah pimpinan Ratu Belanda.

Pertempuran melawan Sekutu dan NICA

Terdapat berbagai pertempuran yang terjadi pada saat masuknya Sekutu dan NICA ke Indonesia, yang saat itu baru menyatakan kemerdekaannya. Pertempuran yang terjadi di antaranya adalah:
  1. Peristiwa 10 November, di daerah Surabaya dan sekitarnya.
  2. Palagan Ambarawa, di daerah Ambarawa, Semarang dan sekitarnya.
  3. Perjuangan Gerilya Jenderal Soedirman, meliputi Jawa Tengah dan Jawa Timur
  4. Bandung Lautan Api, di daerah Bandung dan sekitarnya.

Inilah Negeri kita Indonesia Raya

Berawal dari diskursus akademik para antropolog Barat di penghujung

abad ke-19, Indonesia lahir sebagai nama ilmiah yang diperuntukkan

bagi kepulauan Hindia-Jauh jajahan VOC. Pemetaan Nusantara sebagai

kapling kolonial bernama Indonesia telah menyulut diskursus

kebangsaan yang panjang, bermula dari polemik kebudayaan sejak tahun
1935 di harian Pudjangga Baru dan Suara Umum, antara Sutan Takdir
Alisjahbana, Sanusi Pane, dan Dr Purbatjaraka.

Menurut penulis, jiwa polemik tersebut adalah persoalan: apakah
Indonesia adalah sebuah negeri yang terberi atau datang dari dalam
diri? �Terberi�, menurut logika STA, karena Indonesia terwujud
melalui pengaplingan kolonial atas negeri kepulauan ini. Adapun bagi
Sanusi Pane, Indonesia itu datang dari dalam diri (melalui sejarah)
karena sang budayawan berpandangan, entitas bernama Indonesia adalah
sambungan sejarah Nusantara yang terus berdialektika semenjak zaman

Di masa kepemimpinannya, Bung Karno pernah mengutip tesis Ernest
Renan untuk merumuskan kebangsaan kita. Dalam esai klasiknya, Qu�est-
ce qu�une nation? (What is a Nation, 1882), Renan menjelaskan bahwa
rasa kebangsaan merupakan endapan sejarah kesamaan nasib sekelompok
orang dan visi masa depan yang mereka bentangkan bersama.

Kemudian pada tahun 1983, buku masyhur Imaginary Communities karangan
Ben Anderson terbit dan melahirkan pemikiran baru tentang rasa
kebangsaan yang berseberang pandangan dengan Renan. Anderson
menggambarkan bahwa sebuah bangsa hanya sebatas konstruksi imajiner
sekelompok orang tentang sebuah komunitas yang berdaulat di atas
publiknya. Pandangan ini dipertegasnya dalam buku �Language and
Power: Exploring Political Cultures in Indonesia� (1990), di mana
bahasa Indonesia sebagai elemen penting mosaik komunitas imajiner
Nusantara kerap kali dimanipulasi elite politik untuk merampungkan
arsitektur kekuasaannya.

Selanjutnya, dalam berbagai perdebatan menyoal rasa keindonesiaan,
pakar-pakar kerap membandingkan relevansi antara kedua tesis ini.
Melalui anjakan ilmiah tersebut, diskursus kebangsaan bagai merajut
kembali polemik yang ditelurkan para budayawan kita
terdahulu: �Indonesia, negeri terberi atau produk sendiri?�

Negeri terberi?

Umumnya, pakar dalam negeri bertendensi menghikmahi keindonesiaan
melalui tesis Renan ketimbang logika Indonesia sebagai negeri
terberi. Namun, mesti disadari bahwa tesis Renan lahir dalam konteks
Eropa abad ke-19. Secara garis besar, negara-bangsa di Eropa abad
pertengahan terbentuk dari kelompok-kelompok suku bangsa dalam
wilayah tertentu yang tertindas dominasi Gereja.

Berbeda dengan kita. Nusantara terdiri atas puluhan ribu pulau dan
memiliki tingkat pluralitas kebudayaan yang tinggi. Meski mosaik
kebangsaan kita disebut-sebut telah bersatu melalui Sumpah Pemuda
1928, tak bisa dinafikan bahwa masyarakat Nusantara tidak memiliki
jejak rekam sejarah tunggal yang bisa merekatkannya secara holistik.

Karena kendurnya tali ikatan sejarahwi inilah, sepanjang riwayat kita
hidup bernegara, rasa kebangsaan ditanamkan dalam masyarakat
Indonesia dengan politik identitas. Seperti pada saat politik etis
dilansir, bukankah bahasa Indonesia (melayu tinggi) dijadikan bahasa
nasional agar Belanda dapat menggenggam Nusantara yang luas sebagai
satuan politik jajahannya? Demikian juga yang dilakukan insan-insan
adiputera kita sendiri, sehingga litani realitas kehidupan kita
bernegara menunjukkan betapa relevannya untuk menghikmahi Indonesia
sebagai negeri terberi.

Pada masa Orde Baru, rezim yang paling lama berkuasa itu melansir
kebijakan pembangunan yang mengatasnamakan kemajuan bangsa. Namun,
keuntungan pembangunan bagai kue yang diperuntukkan untuk sekelompok
orang saja, rakyat banyak hanya disisihkan remah-remahnya. Pancang
kekuasaan Orde Baru bak piramida kurban, di mana para pejabat dan
pengusaha merampas hak-hak rakyat dan menari-nari di atas
penderitaannya. Betapa relevannya pengumpamaan sosiolog kita yang
skeptis itu, negeri ini bagai Republik Kapling di mana setiap jengkal
dan petak bumi Nusantara ini telah dipecah-pecah dalam satuan kapling
ekonomi politik.

Di manakah rasa kebangsaan yang bisa meredam tingkah korup di antara
rekan-rekan sebangsa? Rasa itu justru direkayasa guna merampungkan
struktur kekuasaan yang korup. Pancasila, ideologi yang dirumuskan
founding fathers kita untuk memfinalisasi Indonesia sebagai sebuah
negara-bangsa, disekap dalam interpretasi-interpretasi sempit
penguasa berupa Manipol-USDEK hingga P4, kemudian dikenakan sebagai
doktrin sakral guna menjaga kesatuan negara dengan menghalalkan cara
yang paling keji sekalipun. Entitas keindonesiaan bak marionette yang
dimainkan oleh tali kendali penguasa. Tariannya hanya mengindahkan
sejumlah elite yang mengendalikannya.

Meneruskan polemik

Bila kenyataan yang tersibak begitu menyakitkan, salahkah paradigma
kita membangsa selama ini? Tidak sepenuhnya demikian. Realitas
seperti Proklamasi Kemerdekaan Indonesia merupakan fakta sejarah yang
ditulis dari perjuangan kebangsaan yang holistik karena berakar dari
aspirasi rakyat Indonesia yang direpresentasikan oleh sejumlah tokoh.

Ihwal-ihwal sejarah yang menggugah rasa senasib sepenanggungan
sebagai sebuah negara-bangsa seperti ini dapat dijadikan tolakan yang
obyektif untuk melihat �Indonesia sebagai produk sendiri�. Ironisnya,
kelanjutan proyek pembangunan rasa kebangsaan kita dicemari oleh
rezim yang pernah menghuni pemerintahan kita, menyebabkan rasa
kebangsaan yang sejati mati suri sebelum bertumbuh.

Kini di tengah tantangan globalisasi dan bangkitnya primordialisme,
revitalisasi keindonesiaan merupakan sebuah kebutuhan mutlak demi
mencegah luruhnya Indonesia menjadi remahan-remahan ideologi
primordial atau menjadi kapling-kapling kapitalisme global. Untuk itu
kita telah dianugerahi dengan dua paradigma kebangsaan oleh para
pendahulu kita.

Ruang polemik antarkedua pandangan ini mesti dibuka bebas agar kita
tidak takabur tatkala menjejakkan kaki untuk menoreh lembaran baru
sejarah yang diliputi hasrat kebersamaan. Polemik tersebut juga akan
menjaga kita dari jebakan kehampaan akan rasa kebangsaan yang sejati,
karena ada pandangan yang meyakinkan kita bahwa Indonesia merupakan
produk sejarah kita sendiri.

Dengan demikian, semoga interaksi kritis di antara dua penalaran yang
berlainan haluan ini mengalir sebagai polemik yang menyehatkan bangsa.

Inilah Prof Djoko Suryo: Belajar dari Sejarah dan Humaniora

Add caption
Sejarah adalah kebajikan. Ia adalah ilmu yang menjadi pangkal untuk memahami seluruh kehidupan manusia beserta peradaban yang sebenarnya. Belajarlah dari sejarah karena ia adalah guru yang akan membawa manusia kepada kearifan.
Sebuah pandangan yang diyakini oleh Prof Dr Djoko Suryo setelah pergulatannya selama puluhan tahun sebagai sejarawan. Guru Besar Sejarah Fakultas Ilmu Budaya Universitas Gadjah Mada Yogyakarta ini mengatakan, begitu banyak nilai-nilai dan pelajaran yang bisa ditarik dari perjalanan kehidupan manusia dalam sejarahnya.
"Kalau orang mempelajari sejarah, berarti ia sedang mempelajari manusia dari segala dimensinya. Manusia yang sebenarnya itu lahir, hidup, berkembang, dan menghadapi perjalanan hidup, mengalami tantangan, dan bisa mencapai keberhasilan, tetapi juga bisa mengalami kegagalan. Dari situlah seluruh pelajaran hidup tersimpan," papar pria kelahiran 30 Desember 1939 ini, Selasa (21/3), di Yogyakarta.
Pelajaran sejarah itu akan bisa ditarik makna dan nilainya sesuai apa yang manusia inginkan. Banyak hal yang bisa dipetik dari contoh- contoh pengalaman-pengalaman masyarakat masa lampau. Dari peperangan, bencana, ataupun perusakan lingkungan hingga mengakibatkan hancurnya peradaban masa lampau.
"Kita bisa memilih mana yang patut kita lakukan dan ditinggalkan karena tidak perlu ditiru. Dan juga, kita bisa melihat apa yang dilakukan masyarakat sekarang dan bagaimana berusaha melahirkan masyarakat masa depan, masyarakat seperti apa yang akan kita ciptakan. Sejarah mengajarkan proses kehidupan manusia dalam tiga dimensi-masa lalu, masa sekarang, dan melihat sejarah masa depan dari sejarah masa lalu," ujarnya.
Sayangnya, kini orang cenderung melihat masa kini dan melupakan sejarah, bahkan dari sejarah pribadinya. Orang pun menjadi tidak berpikir akan sejarah masa depan.
"Orang kini digoda oleh kekinian saja. Apa yang sekarang sedang tren. Mereka menjadi terbius, sehingga yang masa depan tidak terpikirkan. Akibatnya, orang merencanakan sesuatu hanya seadanya saja," katanya.
Sejarah kehidupan tersingkirkan. Manusia masa kini, menurut Djoko, cenderung kesulitan bahkan tidak bisa lagi merenung karena cepatnya perubahan zaman yang serba pragmatis. Anak-anak muda pun tidak sempat lagi merekam, merenungkan, dan merefleksikan apa yang sudah terjadi, sehingga orang cenderung cepat saja melupakan yang sudah terjadi.
"Peristiwa cepat lewat dan tergantikan peristiwa baru sehingga tidak sempat melihat apa yang sudah terjadi. Situasi itu mengakibatkan kita pun tidak mampu melahirkan pengetahuan dan pemahaman dari masa lampau. Akhirnya, kita tidak bisa belajar dari sejarah," tutur Djoko.
Di sinilah, bidang ilmu-ilmu humaniora atau ilmu tentang kemanusiaan memiliki perannya. Humaniora mempelajari manusia menghadapi perubahan dalam setiap bentuknya, lambat atau cepat.
"Ilmu humaniora itu penting dipelajari, di samping mempelajari ilmu yang canggih-canggih. Ilmu science itu kan muncul dari basis peradaban dan basis kebudayaan. Basisnya dulu adalah humaniora dan melalui itulah manusia memiliki kemampuan berpikir, berkreasi, bercita-cita, dan berimajinasi, maka tumbuh penciptaan. Oleh karena itulah, humaniora tetap memegang peranan penting," ujar Djoko.
Kini, lanjut Djoko, generasi muda kurang memiliki ruang dan kesempatan untuk berimajinasi. Yang ada hanya ingin serba cepat tanpa proses. Akhirnya, hanya menjadi pemakai dan pengekor teknologi. "Sejarah muncul dari penciptaan-penciptaan," ucap Djoko. Untuk itulah, ruang untuk menjadi kreatif itu yang perlu dibangun, ruang untuk berimajinasi. Sebuah ruang yang banyak dimiliki masa lampau yang dibangun melalui ilmu humaniora. Sejarah telah mengajarkan, maka belajarlah dari sejarah.
