People who influences us in their unique fields - Part 1

-- BC & Early AD--


1. Confucius (Chinese: 孔子; pinyin: Kǒng zǐ; Wade–Giles: K'ung-tzu, or Chinese: 孔夫子; pinyin: Kǒng Fūzǐ; Wade–Giles: K'ung-fu-tzu), literally "Master Kong", (traditionally September 28, 551 BC – 479 BC) was a Chinese thinker and social philosopher of the Spring and Autumn Period.


His philosophy emphasized personal and governmental morality, correctness of social relationships, justice and sincerity. These values gained prominence in China over other doctrines, such as Legalism (法家) or Taoism (道家) during the Han Dynasty (206 BC – 220 AD). Confucius' thoughts have been developed into a system of philosophy known as Confucianism (儒家). It was introduced to Europe by the Italian Jesuit Matteo Ricci, who was the first to Latinise the name as "Confucius".


His teachings may be found in the Analects of Confucius (論語), a collection of "brief aphoristic fragments", which was compiled many years after his death. For nearly 2,000 years he was thought to be the editor or author of all the Five Classics (五經) such as the Classic of Rites (禮記) (editor), and the Spring and Autumn Annals (春秋) (author).


Kong Qiu (孔丘), as Confucius is commonly known, is a combination of his surname (孔) and his given name (丘), and he was also known as Zhong Ni (仲尼), which is his courtesy name. He was born in 551 BC in the Lu state (This state was in the south of modern-day Shandong Province) in the later days of the Spring and Autumn Period. Confucius was from a warrior family. His father Shulianghe (叔梁紇) was a famous warrior who had military exploits in two battles and owned a fiefdom. Confucius lost his father when he was three years old, and then his mother Yan Zhengzai (顏徵在) took him and left the fiefdom because as a concubine (妾), she wanted to avoid mistreatment from Shulianghe's formal wife. Thus, Confucius lived in poverty with his mother since childhood. With the support and encouragement of his mother, Confucius was very diligent in his studies. When Confucius was seventeen years old, his mother died as a result of illness and overwork. Three years later, Confucius married a young woman who was from the Qiguan family (亓官氏) of the [[Song (state)|Song state (宋)]]. Though he had a mild tempered wife who loved him, he left his family to strive for his ideals. Confucius sought to revive the perfect virtue of Huaxia (Chinese civilization) and the classical properties of the Western Zhou Dynasty to build a great, harmonious and humanistic society.


Confucius's works are studied by many scholars in many other Asian countries, particularly those in the Sinosphere, such as Korea, Japan and Vietnam. Many of those countries still hold the traditional memorial ceremony every year.


The works of Confucius were translated into European languages through the agency of Jesuit scholars stationed in China. Matteo Ricci started to report on the thoughts of Confucius, and father Prospero Intorcetta published the life and works of Confucius into Latin in 1687. It is thought that such works had considerable importance on European thinkers of the period, particularly among the Deists and other philosophical groups of the Enlightenment who were interested by the integration of the system of morality of Confucius into Western civilization.


The Ahmadiyya Muslim Community believes Confucius was a Divine Prophet of God, as was Lao-Tzu and other eminent Chinese personages.


2. Aristotle (Greek: Ἀριστοτέλης, Aristotélēs) (384 BC – 322 BC) was a Greek philosopher, a student of Plato and teacher of Alexander the Great. His writings cover many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, politics, government, ethics, biology, and zoology. Together with Plato and Socrates (Plato's teacher), Aristotle is one of the most important founding figures in Western philosophy. Aristotle's writings were the first to create a comprehensive system of Western philosophy, encompassing morality and aesthetics, logic and science, politics and metaphysics.

Aristotle's views on the physical sciences profoundly shaped medieval scholarship, and their influence extended well into the Renaissance, although they were ultimately replaced by Newtonian physics. In the zoological sciences, some of his observations were confirmed to be accurate only in the 19th century. His works contain the earliest known formal study of logic, which was incorporated in the late 19th century into modern formal logic. 

In metaphysics, Aristotelianism had a profound influence on philosophical and theological thinking in the Islamic and Jewish traditions in the Middle Ages, and it continues to influence Christian theology, especially the scholastic tradition of the Catholic Church and some strains of Eastern Orthodox thought. 

His ethics, though always influential, gained renewed interest with the modern advent of virtue ethics. All aspects of Aristotle's philosophy continue to be the object of active academic study today. Though Aristotle wrote many elegant treatises and dialogues (Cicero described his literary style as "a river of gold"), it is thought that the majority of his writings are now lost and only about one-third of the original works have survived.

What we today call Aristotelian logic, Aristotle himself would have labeled "analytics". The term "logic" he reserved to mean dialectics. Most of Aristotle's work is probably not in its original form, since it was most likely edited by students and later lecturers. The logical works of Aristotle were compiled into six books in about the early 1st century AD:
1. Categories
2. On Interpretation
3. Prior Analytics
4. Posterior Analytics
5. Topics
6. On Sophistical Refutations

The order of the books (or the teachings from which they are composed) is not certain, but this list was derived from analysis of Aristotle's writings. It goes from the basics, the analysis of simple terms in the Categories, the analysis of propositions and their elementary relations in On Interpretation, to the study of more complex forms, namely, syllogisms (in the Analytics) and dialectics (in the Topics and Sophistical Refutations). The first three treatises form the core of the logical theory stricto sensu: the grammar of the language of logic and the correctness rules of reasoning. There is one volume of Aristotle's concerning logic not found in the Organon, namely the fourth book of Metaphysics


3. Plutarch, born Plutarchos (Greek: Πλούταρχος) then, on his becoming a Roman citizen, Lucius Mestrius Plutarchus (Μέστριος Πλούταρχος), c. 46 – 120 AD, was a Greek historian, biographer, essayist, and Middle Platonist known primarily for his Parallel Lives and Moralia. He was born to a prominent family in Chaeronea, Boeotia, a town about twenty miles east of Delphi.


"The soul, being eternal, after death is like a caged bird that has been released. If it has been a long time in the body, and has become tame by many affairs and long habit, the soul will immediately take another body and once again become involved in the troubles of the world. The worst thing about old age is that the soul's memory of the other world grows dim, while at the same time its attachment to things of this world becomes so strong that the soul tends to retain the form that it had in the body. But that soul which remains only a short time within a body, until liberated by the higher powers, quickly recovers its fire and goes on to higher things."
Plutarch (The Consolation, Moralia).


Plutarch's writings had an enormous influence on English and French literature. Shakespeare in his plays paraphrased parts of Thomas North's translation of selected Lives, and occasionally quoted from them in verbatim.


Ralph Waldo Emerson and the Transcendentalists were greatly influenced by the Moralia — so much so, in fact, that Emerson called the Lives "a bible for heroes" in his glowing introduction to the five-volume 19th-century edition. He also opined that it was impossible to "read Plutarch without a tingling of the blood; and I accept the saying of the Chinese Mencius: 'A sage is the instructor of a hundred ages. When the manners of Loo are heard of, the stupid become intelligent, and the wavering, determined.'"


Montaigne's own Essays draw extensively on Plutarch's Moralia and are consciously modelled on the Greek's easygoing and discursive inquiries into science, manners, customs and beliefs. Essays contains more than 400 references to Plutarch and his works.


James Boswell quoted Plutarch on writing lives, rather than biographies, in the introduction to his own Life of Samuel Johnson. Other admirers included Ben Jonson, John Dryden, Alexander Hamilton, John Milton, and Francis Bacon, as well as such disparate figures as Cotton Mather and Robert Browning.


Plutarch's influence declined in the 19th and 20th centuries, but it remains embedded in the popular ideas of Greek and Roman history.


4. Zhuge Liang 諸葛亮 (181-234) was Chancellor of Shu Han during the Three Kingdoms period of Chinese history. He is often recognised as the greatest and most accomplished strategist of his era.


Often depicted wearing a robe and holding a fan made of crane feathers, Zhuge was not only an important military strategist and statesman; he was also an accomplished scholar and inventor. His reputation as an intelligent and learned scholar grew even while he was living in relative seclusion, earning him the nickname Wòlóng (臥龍, literally Crouching Dragon).


Zhuge is an uncommon two-character compound family name. His name – even his surname alone – has become synonymous with intelligence and tactics in Chinese culture.


Zhuge Liang's name is synonymous with wisdom in the Chinese language. He was believed to be the inventor of the Mantou, the landmine and a mysterious, efficient automatic transportation device (initially used for grain) described as a "wooden ox and flowing horse" (木牛流馬), which is sometimes identified with the wheelbarrow. Although he is often credited with the invention of the repeating crossbow which is named after him and called the Zhuge Nu, i.e. Zhuge Crossbow, this type of semi-automatic crossbow is an improved version of a model that first appeared during the Warring States Period (though there is debate whether the original Warring States Period bow was semi-automatic, or rather shot multiple bolts at once). Nevertheless, Zhuge Liang's version could shoot further and faster. He is also credited with constructing the mysterious Stone Sentinel Maze, an array of stone piles that is said to produce supernatural phenomenon, located near Baidicheng. An early type of hot air balloon used for military signalling called the Kongming lantern is also named after him.


Some books popularly attributed to Zhuge Liang can be found today. For example, the Thirty-Six Stratagems, and Mastering the Art of War (not to be confused with Sun Tzu's The Art of War) are two of Zhuge's works that are generally available. Supposedly, his mastery of infantry and cavalry formation tactics based upon the Taoist I-Ching were unrivalled. His petition Chu Shi Biao was written prior to the Northern Campaigns and it provided a salutary reflection of Zhuge Liang's unwavering loyalty to Shu-Han. The petition moved readers to tears.


--1400s - 1800s--


1. Leonardo di ser Piero da Vinci (April 15, 1452 – May 2, 1519) was an Italian polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist and writer. Leonardo has often been described as the archetype of the Renaissance man, a man whose unquenchable curiosity was equaled only by his powers of invention. He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived. According to art historian Helen Gardner, the scope and depth of his interests were without precedent and "his mind and personality seem to us superhuman, the man himself mysterious and remote". Marco Rosci points out, however, that while there is much speculation about Leonardo, his vision of the world is essentially logical rather than mysterious, and that the empirical methods he employed were unusual for his time.


Born the illegitimate son of a notary, Piero da Vinci, and a peasant woman, Caterina, at Vinci in the region of Florence, Leonardo was educated in the studio of the renowned Florentine painter, Verrocchio. Much of his earlier working life was spent in the service of Ludovico il Moro in Milan. He later worked in Rome, Bologna and Venice and spent his last years in France, at the home awarded him by Francis I.
Leonardo was and is renowned primarily as a painter. Two of his works, the Mona Lisa and The Last Supper, are the most famous, most reproduced and most parodied portrait and religious paintings of all time, respectively, their fame approached only by Michelangelo's Creation of Adam. Leonardo's drawing of the Vitruvian Man is also regarded as a cultural icon, being reproduced on everything from the euro to text books to t-shirts. Perhaps fifteen of his paintings survive, the small number due to his constant, and frequently disastrous, experimentation with new techniques, and his chronic procrastination. Nevertheless, these few works, together with his notebooks, which contain drawings, scientific diagrams, and his thoughts on the nature of painting, compose a contribution to later generations of artists only rivalled by that of his contemporary, Michelangelo.


Leonardo is revered for his technological ingenuity. He conceptualised a helicopter, a tank, concentrated solar power, a calculator, the double hull and outlined a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or were even feasible during his lifetime, but some of his smaller inventions, such as an automated bobbin winder and a machine for testing the tensile strength of wire, entered the world of manufacturing unheralded. As a scientist, he greatly advanced the state of knowledge in the fields of anatomy, civil engineering, optics, and hydrodynamics.


2. René Descartes (31 March 1596 – 11 February 1650) (Latinized form: Renatus Cartesius; adjectival form: "Cartesian"),[2] was a French philosopher, mathematician, physicist, and writer who spent most of his adult life in the Dutch Republic.


He is best known for the philosophical statement "Cogito ergo sum" (French: Je pense, donc je suis; English: I think, therefore I am; or I am thinking, therefore I exist), found in part IV of Discourse on the Method (1637 – written in French but with inclusion of "Cogito ergo sum") and §7 of part I of Principles of Philosophy (1644 – written in Latin).


3. Sir Francis Bacon, 1st Viscount Saint Alban, KC (22 January 1561 – 9 April 1626) was an English philosopher, statesman, scientist, lawyer, jurist and author. He famously died of pneumonia contracted while studying the effects of freezing on the preservation of meat. He served both as Attorney General and Lord Chancellor of England. Although his political career ended in disgrace, he remained extremely influential through his works, especially as philosophical advocate and practitioner of the scientific method and pioneer in the scientific revolution.


Bacon has been called the father of empiricism. His works established and popularized inductive methodologies for scientific inquiry, often called the Baconian method or simply, the scientific method. His demand for a planned procedure of investigating all things natural marked a new turn in the rhetorical and theoretical framework for science, much of which still surrounds conceptions of proper methodology today. His dedication probably led to his death so bringing him into a rare historical group of scientists who were killed by their own experiments.


Bacon's works include his Essays, as well as the Colours of Good and Evil and the Meditationes Sacrae, all published in 1597. His famous aphorism, "knowledge is power", is found in the Meditations. He published Of the Proficience and Advancement of Learning, Divine and Human in 1605. Bacon also wrote In felicem memoriam Elizabethae, a eulogy for the queen written in 1609; and various philosophical works which constitute the fragmentary and incomplete Instauratio magna (Great Renewal), the most important part of which is the Novum Organum (New Instrument, published 1620)


In 1623 Bacon expressed his aspirations and ideals in New Atlantis. Released in 1627, this was his creation of an ideal land where "generosity and enlightenment, dignity and splendor, piety and public spirit" were the commonly held qualities of the inhabitants of Bensalem. In this work, he portrayed a vision of the future of human discovery and knowledge. The plan and organization of his ideal college, "Solomon's House", envisioned the modern research university in both applied and pure science.


4. Sir Isaac Newton FRS (4 January 1643 – 31 March 1727 [OS: 25 December 1642 – 20 March 1726]) was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian who is considered by many scholars and members of the general public to be one of the most influential people in human history. His 1687 publication of the Philosophiæ Naturalis Principia Mathematica (usually called the Principia) is considered to be among the most influential books in the history of science, laying the groundwork for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the Scientific Revolution.


Newton built the first practical reflecting telescope and developed a theory of colour based on the observation that a prism decomposes white light into the many colours that form the visible spectrum. He also formulated an empirical law of cooling and studied the speed of sound.


In mathematics, Newton shares the credit with Gottfried Leibniz for the development of the differential and integral calculus. He also demonstrated the generalised binomial theorem, developed Newton's method for approximating the roots of a function, and contributed to the study of power series.


In a 2005 survey of members of Britain's Royal Society asking who had the greater effect on the history of science and made the greater contribution to humankind, Newton or Albert Einstein. Royal Society scientists deemed Newton to have made the greater overall contribution on both.


Newton was also highly religious, though an unorthodox Christian, writing more on Biblical hermeneutics and occult studies than the natural science for which he is remembered today.


5. Johann Wolfgang von Goethe (28 August 1749  – 22 March 1832) was a German writer and polymath. Goethe is considered by many to be the most important writer in the German language and one of the most important thinkers in Western culture. Goethe's works span the fields of poetry, drama, literature, theology, philosophy, and science. His magnum opus, lauded as one of the peaks of world literature, is the drama Faust. Goethe's other well-known literary works include his numerous poems, the Bildungsroman Wilhelm Meister's Apprenticeship, and the epistolary novel The Sorrows of Young Werther.


Goethe was one of the key figures of German literature and the movement of Weimar Classicism in the late 18th and early 19th centuries; this movement coincides with Enlightenment, Sentimentality (Empfindsamkeit), Sturm und Drang and Romanticism. The author of the scientific text Theory of Colours, his influential ideas on plant and animal morphology and homology were extended and developed by 19th century naturalists including Charles Darwin. He also served at length as the Privy Councilor of the duchy of Saxe-Weimar.


Goethe's influence spread across Europe, and for the next century his works were a major source of inspiration in music, drama, poetry and philosophy. Early in his career, however, he wondered whether painting might be his true vocation; late in his life, he expressed the expectation that he would ultimately be remembered above all for his work on colour.


6. Ralph Waldo Emerson (May 25, 1803 – April 27, 1882) was an American lecturer, essayist, and poet, best remembered for leading the Transcendentalist movement of the mid-19th century. He was seen as a champion of individualism and a prescient critic of the countervailing pressures of society, and he disseminated his thought through dozens of published essays and more than 1,500 public lectures across the United States.
Emerson gradually moved away from the religious and social beliefs of his contemporaries, formulating and expressing the philosophy of Transcendentalism in his 1836 essay, Nature. Following this ground-breaking work, he gave a speech entitled The American Scholar in 1837, which Oliver Wendell Holmes, Sr. considered to be America's "Intellectual Declaration of Independence". Considered one of the great lecturers of the time, Emerson had an enthusiasm and respect for his audience that enraptured crowds.


Emerson wrote on a number of subjects, never espousing fixed philosophical tenets, but developing certain ideas such as individuality, freedom, the ability for man to realize almost anything, and the relationship between the soul and the surrounding world. Emerson's "nature" was more philosophical than naturalistic; "Philosophically considered, the universe is composed of Nature and the Soul."


While his writing style can be seen as somewhat impenetrable, and was thought so even in his own time, Emerson's essays remain one of the linchpins of American thinking, and Emerson's work has influenced nearly every generation of thinker, writer and poet since his time. When asked to sum up his work, he said his central doctrine was "the infinitude of the private man."


-- Recent Famous People --


1. Robert Lee Frost (March 26, 1874 – January 29, 1963) was an American poet. He is highly regarded for his realistic depictions of rural life and his command of American colloquial speech.  A popular and often-quoted poet, Frost was honored frequently during his lifetime, receiving four Pulitzer Prizes for Poetry.

"The Road Not Taken" is a poem by Robert Frost, published in 1916 in the collection Mountain Interval. It is the first poem in the volume and is printed in italics. The title is often mistakenly given as "The Road Less Traveled", from the penultimate line: "I took the one less traveled by".

The Road Not Taken
Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;
Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,
And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference

Frost intended the poem as a gentle jab at his great friend and fellow poet Edward Thomas, with whom he used to take walks through the forest (Thomas always complained at the end that they should have taken a different path) and seemed amused at the interpretation of the poem as inspirational.

According to the popular interpretation, the poem is inspirational, a paean to individualism and non-conformism. Popular interpretations take the last two lines literally, as meaning that the speaker was a courageous nonconformist in taking a road few other people had taken.

The ironic interpretation, widely held by critics, is that the poem is instead about personal myth-making and rationalizing our decisions, whether with pride or with regret. In this view, "The Road Not Taken" "is perhaps the most famous example of Frost's own claims to conscious irony and 'the best example in all of American poetry of a wolf in sheep's clothing.'

2. Margaret Mead (December 16, 1901 – November 15, 1978) was an American cultural anthropologist, who was frequently a featured writer and speaker in the mass media throughout the 1960s and 1970s.
She was both a popularizer of the insights of anthropology into modern American and Western culture, and also a respected, if controversial, academic anthropologist. Her reports about the attitudes towards sex in South Pacific and Southeast Asian traditional cultures amply informed the 1960s sexual revolution. Mead was a champion of broadened sexual mores within a context of traditional western religious life.  She was married three times and while Margaret Mead never openly identified herself as lesbian or bisexual, the details of her relationship with Ruth Benedict have led others to so identify her. In her writings she proposed that it is to be expected that an individual's sexual orientation may evolve throughout life. She spent her last years in a close personal and professional collaboration with anthropologist Rhoda Metraux, with whom she lived from 1955 until her death in 1978. Letters between the two published in 2006 with the permission of Mead's daughter clearly express a romantic relationship.

On January 19, 1979, President Jimmy Carter announced that he was awarding the Presidential Medal of Freedom posthumously to Mead. U.N. Ambassador Andrew Young presented the award to Mead's daughter at a special program honoring Mead's contributions, sponsored by the American Museum of Natural History, where she spent many years of her career. The citation read:

"Margaret Mead was both a student of civilization and an exemplar of it. To a public of millions, she brought the central insight of cultural anthropology: that varying cultural patterns express an underlying human unity. She mastered her discipline, but she also transcended it. Intrepid, independent, plain spoken, fearless, she remains a model for the young and a teacher from whom all may learn."

3. Stephen William Hawking, CH, CBE, FRS, FRSA (born 8 January 1942). is an English theoretical physicist and cosmologist, whose scientific career spans over forty years. His books and public appearances have made him an academic celebrity. He is an Honorary Fellow of the Royal Society of Arts, a lifetime member of the Pontifical Academy of Sciences, and in 2009 was awarded the Presidential Medal of Freedom, the highest civilian award in the United States.


Hawking was the Lucasian Professor of Mathematics at the University of Cambridge for thirty years, taking up the post in 1979 and retiring on 1 October 2009. He is also a Fellow of Gonville and Caius College, Cambridge and a Distinguished Research Chair at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario. He is known for his contributions to the fields of cosmology and quantum gravity, especially in the context of black holes. He has also achieved success with works of popular science in which he discusses his own theories and cosmology in general; these include the runaway best seller A Brief History of Time, which stayed on the British Sunday Times bestsellers list for a record-breaking 237 weeks.


Hawking's key scientific works to date have included providing, with Roger Penrose, theorems regarding gravitational singularities in the framework of general relativity, and the theoretical prediction that black holes should emit radiation, which is today known as Hawking radiation (or sometimes as Bekenstein–Hawking radiation).


Hawking has a neuro-muscular dystrophy that is related to amyotrophic lateral sclerosis, a condition that has progressed over the years and has left him almost completely paralysed.

4. William Butler Yeats (13 June 1865 – 28 January 1939) was an Irish poet and dramatist, and one of the foremost figures of 20th century literature. A pillar of both the Irish and British literary establishments, in his later years Yeats served as an Irish Senator for two terms. He was a driving force behind the Irish Literary Revival, and along with Lady Gregory and Edward Martyn founded the Abbey Theatre, serving as its chief during its early years. In 1923 he was awarded the Nobel Prize in Literature for what the Nobel Committee described as "inspired poetry, which in a highly artistic form gives expression to the spirit of a whole nation." He was the first Irishman so honored. Yeats is generally considered one of the few writers who completed their greatest works after being awarded the Nobel Prize; such works include The Tower (1928) and The Winding Stair and Other Poems (1929).

Yeats is generally considered to be one of the twentieth century's key English language poets. He can be considered a Symbolist poet in that he used allusive imagery and symbolic structures throughout his career. Yeats chose words and assembled them so that in addition to a particular meaning they suggest other abstract thoughts that may seem more significant and resonant. His use of symbols is usually something physical which is used both to be itself and to suggest other, perhaps immaterial, timeless qualities.

Unlike other modernists who experimented with free verse, Yeats was a master of the traditional forms. The impact of modernism on his work can be seen in the increasing abandonment of the more conventionally poetic diction of his early work in favour of the more austere language and more direct approach to his themes that increasingly characterises the poetry and plays of his middle period, comprising the volumes In the Seven Woods, Responsibilities and The Green Helmet. His later poetry and plays are written in a more personal vein, and the works written in the last twenty years of his life include mention of his son and daughter, as well as meditations on the experience of growing old.

5. Albert Einstein (14 March 1879 – 18 April 1955) was a theoretical physicist, philosopher and author who is widely regarded as one of the most influential and best known scientists and intellectuals of all time. A German-Swiss Nobel laureate, he is often regarded as the father of modern physics. He received the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect".

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.

On the eve of World War II in 1939, he personally alerted President Franklin D. Roosevelt that Germany might be developing an atomic weapon. As a result, Roosevelt advocated uranium research and the top secret Manhattan Project, which led to the U.S. becoming the only country to possess nuclear weapons during the war.

Einstein published more than 300 scientific along with over 150 non-scientific works, and received honorary doctorate degrees in science, medicine and philosophy from many European and American universities; he also wrote about various philosophical and political subjects such as socialism and international relations. His great intelligence and originality has made the word "Einstein" synonymous with genius.

6. Sri Lankabhimanya (a title) Sir Arthur Charles Clarke, CBE, FRAS (16 December 1917 – 19 March 2008) was a British science fiction author, inventor, and futurist, most famous for the novel 2001: A Space Odyssey, written in parallel with the script for the eponymous film, co-written with film-director Stanley Kubrick; and as a host and commentator in the British television series Mysterious World. For many years, Robert A. Heinlein, Isaac Asimov, and Arthur C. Clarke were known as the "Big Three" of science fiction.

7.  Alvin Toffler (born October 4, 1928 in New York City) is an American writer and futurist, known for his works discussing the digital revolution, communication revolution, corporate revolution and technological singularity.

Toffler explains, "Society needs people who take care of the elderly and who know how to be compassionate and honest. Society needs people who work in hospitals. Society needs all kinds of skills that are not just cognitive; they're emotional, they're affectional. You can't run the society on data and computers alone." Toffler also states, in Rethinking the Future, that "The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn."
