Leonardo da Vinci Leonardo is revered for his technological ingenuity. He conceptualised flying machines, an armoured vehicle, concentrated solar power, an adding machine, and the double hull, also outlining a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or were even feasible during his lifetime,[nb 2] 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.[nb 3] He made substantial discoveries in anatomy, civil engineering, optics, and hydrodynamics, but he did not publish his findings and they had no direct influence on later science.

Charles Darwin Charles Robert Darwin, FRS (/ˈdɑrwɪn/; 12 February 1809 – 19 April 1882) was an English naturalist and geologist, best known for his contributions to evolutionary theory.[I] He established that all species of life have descended over time from common ancestors, and in a joint publication with Alfred Russel Wallace introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s the scientific community and much of the general public had accepted evolution as a fact. Biography Early life and education Painting of seven-year-old Charles Darwin in 1816.

How Anyone Can Become a Good Public Speaker Thomas Edison Edison as a boy Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Edison was a prolific inventor, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany. His advanced work in these fields was an outgrowth of his early career as a telegraph operator. Early life Thomas Edison was born in Milan, Ohio, and grew up in Port Huron, Michigan. In school, the young Edison's mind often wandered, and his teacher, the Reverend Engle, was overheard calling him "addled". Edison developed hearing problems at an early age. Edison's family moved to Port Huron, Michigan, after the railroad bypassed Milan in 1854 and business declined; his life there was bittersweet.

James Clerk Maxwell James Clerk Maxwell FRS FRSE (13 June 1831 – 5 November 1879) was a Scottish mathematical physicist. His most notable achievement was to formulate the classical theory of electromagnetic radiation, bringing together for the first time electricity, magnetism, and light as manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the "second great unification in physics" after the first one realised by Isaac Newton. With the publication of A Dynamical Theory of the Electromagnetic Field in 1865, Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. Maxwell proposed that light is an undulation in the same medium that is the cause of electric and magnetic phenomena. The unification of light and electrical phenomena led to the prediction of the existence of radio waves. Life Early life, 1831–39 Education, 1839–47 Edinburgh Academy, where Maxwell was schooled ...
15 Stunning Examples Of Owl Camouflage Owls are fascinating and beautiful birds we rarely get to see up close and personal. Owls come out at night in order to avoid competition over prey with other large birds. This alone says a great deal about the owls’ personality. Owls like to creep in the shadows, remaining hidden and discrete at all times in order to stay safe as well as catch prey. It certainly helps that they have incredibly silent wings, and the ability to sit very still for long periods of time. It’s not easy to find all of the owls in these pictures. Owls have vivid coat colors that help them remain hidden depending on the environment they reside in. Owls like to use leaves as a way to keep cover, places with thick leave coverage often host a few hide away owls, watching and waiting for nightfall to arrive. Owls are never one solid color, which makes them harder to see at night because not one color stands out. Some owls don’t reside in trees but instead burrow under ground. Trending Today
Benjamin Franklin Benjamin Franklin FRS (January 17, 1706 [O.S. January 6, 1705] – April 17, 1790) was one of the Founding Fathers of the United States. A renowned polymath, Franklin was a leading author, printer, political theorist, politician, postmaster, scientist, inventor, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. Franklin, always proud of his working class roots, became a successful newspaper editor and printer in Philadelphia, the leading city in the colonies. With two partners he published the Pennsylvania Chronicle, a newspaper that was known for its revolutionary sentiments and criticisms of the British policies. He played a major role in establishing the University of Pennsylvania and was elected the first president of the American Philosophical Society. Early life in Boston Franklin's birthplace on Milk Street, Boston, Massachusetts Chess
Isaac Newton Sir Isaac Newton PRS MP (/ˈnjuːtən/; 25 December 1642 – 20 March 1726/7) was an English physicist and mathematician (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations for classical mechanics. Newton made seminal contributions to optics, and he shares credit with Gottfried Leibniz for the development of calculus. 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 of the visible spectrum. He formulated an empirical law of cooling, studied the speed of sound, and introduced the notion of a Newtonian fluid. Life Early life Isaac Newton (Bolton, Sarah K. Middle years Mathematics Optics

20 Most Influential Women Intellectuals Women intellectuals have been playing an increasingly important role in shaping thought and culture. Here is SuperScholar’s list of the 20 most influential living women intellectuals. Margaret Atwood (1939– ), an iconic Canadian feminist novelist, expresses both the “goddess” and “activist” modes of the mid-twentieth century movement, via a confrontational style that gained converts by avoiding both violence and eccentricity. Aung San Suu Kyi (1945– ), a Nobel Peace Prize laureate and scholar living under house arrest and many other restrictions imposed by her native Burma’s (Myanmar’s) military rulers, leads a popular political movement and party whose non-violence and civil disobedience offer hope for eventual democratic government. Karen Armstrong (1944– ), formerly a Roman Catholic nun in her native Britain and widely considered a force for ecumenism, now considers herself a “creative monotheist,” whose many books offer iconoclasm regarding major monotheist religions.
Alhazen In medieval Europe, he was honored as Ptolemaeus Secundus ("Ptolemy the Second") or simply called "The Physicist". He is also sometimes called al-Basri (Arabic: البصري) after Basra, his birthplace.

Galileo Galilei Galileo Galilei (Italian pronunciation: [ɡaliˈlɛːo ɡaliˈlɛi]; 15 February 1564 – 8 January 1642), often known mononymously as Galileo, was an Italian physicist, mathematician, engineer, astronomer, and philosopher who played a major role in the scientific revolution during the Renaissance. His achievements include improvements to the telescope and consequent astronomical observations and support for Copernicanism. Galileo has been called the "father of modern observational astronomy", the "father of modern physics", the "father of science", and "the father of modern science". Early life Galileo was born in Pisa (then part of the Duchy of Florence), Italy, in 1564, the first of six children of Vincenzo Galilei, a famous lutenist, composer, and music theorist, and Giulia Ammannati. Although a genuinely pious Roman Catholic, Galileo fathered three children out of wedlock with Marina Gamba. Career as a scientist Galileo, Kepler and theories of tides
