Wolfgang Pauli: Men of Ideas

Written by
Wolfgang Pauli (1900-1958) was an Austrian theoretical physicist. He is noted for his discovery of the exclusion principle, a principle that underpins the structure of matter. In 1945, Pauli received the Nobel Price in physics for his work on Exclusion Principle (also called the Pauli Principle). The Exclusion Principle states that no two electrons could exist in the same quantum state, identified by four quantum numbers including his two-valued degree of freedom. Pauli identified the electron’s spin degree of freedom. His research played a key role in validating Heisenberg’s matrix theory of quantum mechanics. Pauli used Heisenberg’s metric theory to…

Neils Bohr : Men of Ideas

Written by
Neils Henrik Bohr (1885-1962) was a Danish physicist. He made fundamental contributions to the understanding of the structure of the atom and to quantum mechanics. For his work in quantum mechanics he received the Nobel Prize in 1922. He later worked on the Manhattan Project that produced the first atomic weapon. Bohr improved Ernest Rutherford’s hypothesis on the structure of the atom; in 1913 he published a paper showing that the electron circled the nucleus of the atom; he further showed the chemical properties of each element is largely determined by the number of electrons circling its nucleus; he also…

Max Born: Men of Ideas

Written by
Max Born (1882-1970) was a German, Jewish physicist and mathematician. He played a crucial role in the development of quantum mechanics, solid state physics and optics. Born was awarded the 1954 Nobel Prize in physics for his Statistical interpretation of quantum mechanics. Born was more a mathematician than anything else. His contribution is rendering the various discoveries on quantum mechanics in mathematical language. Born was a professor of physics at Berlin University and many of his students proceeded to win the Nobel Prize in physics. As a Jew, the Nazis made life difficult for Born and he emigrated to the…

Steve Jobs and Bill Gates: Men of Ideas

Written by
Steve Jobs (1955- ) and Bill Gates (1955- ) are two America university drop outs whose computer and internet wizardry has come to represent the face of computers and the Internet. Whereas they were not the actual inventors of computer or the Internet but they represent the computer as we now know it. Steve Job and his friend Steve Wozniak, were the first to translate big computers into small computers, what is now called personal computers. They built the first table top computers (Apple) and marketed them. Other people got into the game and now there are tons of computer…

Albert Einstein: Men of Ideas

Written by
Albert Einstein (1879-1955) was a German, Jewish mathematician and physicist. He is best known for his theory of special relativity, his mass energy equation (E=MC2) and his translation of Planck’s notion that light is emitted in quanta to photons. Einstein’s special relativity theory reconciled mechanics to electromagnetism and his general relativity theory improved on Newton’s gravitation theory. Einstein made other contributions to physics but his special and general relativity and studies on light are considered his seminal contributions to science. Upon leaving college, Einstein worked at a Zurich Patents’ office. While there he had time to study what was dear…

Fred Hoyle: Men of Ideas

Written by
Fred Hoyle (1915-2001) was an English astronomer. He is best remembered for his work on stellar nucleosynthesis and his contrarian nature, his taking opposing perspectives on what atheistic scientists would like the public to believe, that there is no God; Hoyle believed in God. Hoyle’s primary scientific work was on stellar nucleosynthesis, how the atoms in stars decay and transmuted to other atoms (different elements). He observed that one particular nuclear reaction, the triple-alpha process, generated carbon. There is a large amount of carbon in the universe making it possible for our carbon based life forms. He speculated on the…

George Gamow: Men of Ideas

Written by
George Gamow (1904-1968) was a Russian theoretical physicist and cosmologist. He contributed to the idea of the Big Bang origin of the universe by demonstrating alpha decay via quantum tunneling, radioactive decay of atoms, star formation and stellar nucleosynthesis. Essentially, Gamow showed how atoms in the sun are formed and how their nucleus eventually decays to release the radiation (light and heath) that we pick up on earth. This understanding of the formation and decay of stars and by generalization the galaxies and the universe contributed to our understanding of the origin of the universe and how it would eventually…

Georges Lamaitre: Men of Ideas

Written by
Georges Lamaitre (1894-1966) was a Belgian physicist and astronomer. In 1931 Lamaitre proposed what is now called the Big Bang hypothesis of the origin of the universe. Einstein had postulated a steady state universe and Friedman and Lamaitre proved other wise that the universe is expanding. Lamaitre posited that the universe began from a primeval atom that exploded and created space, time and matter. Friedman merely talked about an expanding universe but it was Lamaitre who hypothesized that the universe had an origin in one atom that exploded and gave rise to it. At first Lemaitre’s hypothesis met with opposition,…

Alexander Friedman: Men of Ideas

Written by
Alexander Friedman (1888-1925) was a Russian, Jewish, mathematician and astronomer. His main contribution to science is positing, in 1922, the hypothesis that the universe is expanding. Edwin Hubble’s 1929 observations proved this hypothesis to be correct. Since Albert Einstein’s special relativity there had been a debate as to whether the universe is static or expanding. Lamaitre’s Big Bang hypothesis of the origin of the Universe and Edwin Hubble’s telescopic observations eventually demonstrated that the universe began at one point and is expanding outwards. The detection of cosmic microwave background radiation also lead to the abandonment of Einstein’s steady state hypothesis…

Ernest Rutherford: Men of Ideas

Written by
Ernest Rutherford (1871-1937) was a New Zealand chemist and physicist; he is considered by many as the founder of nuclear physics. He posited the thesis that the electron orbits around the nucleus of the atom (the nucleus consists of the proton and neutron). For this discovery he was awarded the Nobel Prize in Chemistry in 1908. Rutherford discovered that the atom has a positively charged nucleus orbited by electrons. He showed that atoms do spontaneously disintegrate (decay) and do so at given rates, that is, took the same amount of time for that to happen (half time); this discovery gave…

Max Planck: Men of Ideas

Written by
Max Planck (1858-1947) was a German physicist. He is generally considered the reluctant founder of quantum mechanics. Planck posited that electromagnetic energy is emitted only in quantized forms (now called Planck’s action quantum, mathematically, F=hv, where h is Planck’s constant). Einstein later demonstrated that light was emitted in photons (quanta). Interestingly, Max Planck initially rejected Einstein’s hypothesis that light is emitted in quanta (photons), a hypothesis Einstein based on Phillipp Lenard’s 1902 discovery of the photoelectric effect. Planck thought that accepting Einstein’s hypothesis would discard Maxwell’s electrodynamics and thereby set physics back y centuries. Planck made other mistakes such as…

William Thomson: Men of Ideas

Written by
William Thomson (1824-1907) was an Irish mathematician, physicist and engineer. He did seminal work on thermodynamics and mathematical analysis of electricity. He developed what is now known as the Kelvin scale (named after him, when he was made the Baron Kelvin) of absolute temperature measurement. Thomson’s greatest work was in heat. Apparently, he was set into motion by Joules demonstration of the mutual convertibility of heat and mechanical work and their mechanical equivalence. Thomson was intrigued and set out to see if there were theoretical explanations of Joules experimental conclusions. Building on the work of Carnot-Clapeyron, Thomson predicted that the…

Ludwig Boltzmann: Men of Ideas

Written by
Ludwig Boltzmann Ludwig Eduard Boltzmann (1844-1908) was an Austrian mathematician and physicist. His most important contribution to physics is statistical mechanics and statistical thermodynamics. He was a supporter of Dalton’s atomic theory and he did so at a time it was controversial (that is, before Ernst Rutherford demonstrated its reality). Boltzmann’s most important contribution is his kinetic theory (of gases) for the distribution for molecular speeds in gases (now called Maxwell-Boltzmann distribution).The Maxwell-Boltzmann distribution and Boltzmann statistics are the foundations of classical statistical mechanics. Boltzmann tried to use his statistics to show that atoms indeed exist (now called Boltzmann’s constant)…

James Clerk Maxwell: Men of Ideas

Written by
James Clerk Maxwell (1831-1879) was a Scottish mathematician and theoretical physicist. His greatest contribution to physics was putting into mathematical equations (now called The Four Equations of Maxwell) discoveries made by several researchers on the nature of electricity, magnetism and inductance. These equations unified electricity and magnetism, as Faraday and others had experimentally demonstrated. Maxwell mathematically showed that light and magnetism are linked, called electromagnetism. This achievement helped found modern physics; it especially contributed to the development of special relativity and quantum mechanics. Maxwell created the first color photographs in 1861. Maxwell showed that electric and magnetic fields travel through…

Michael Faraday: Men of Ideas

Written by
Michael Faraday (1791-1867) was an English chemist and physicist. Though not formally trained in either chemistry, physics or mathematics, Faraday made seminal contributions to our understanding of electromagnetism and electrochemistry. Through his studies he established that electricity and magnetism go hand in hand and are essentially the same force. He established the basis for electricity as we now know it. He invented the electromagnetic rotary which formed the basis of electric motor technology. In Chemistry, Faraday discovered benzene, invented the Bunsen burner (now an indispensable source of heat in chemistry laboratories), and contributed to our understanding of anode, cathode, electrode,…

Howard Flory: Men of Ideas

Written by
Howard Florey (1898-1968) was an Australian pharmacologist. His notable contribution to medicine was finding a way to extract penicillin and mass produce it and use it to immunize the public against bacterial infection. Apparently, he had read Alexander Fleming’s paper regarding the extraction of penicillin from penicillin and noted Fleming’s difficulties in extracting large enough quantities of penicillin to make it useful for immunizing the public. Fleming had given up on his efforts to extract large quantities of penicillin. Florey and his associate, Ernst Boris Chain, found a way to accomplish what Fleming could not. For his work along with…

Alexander Fleming : Men of Ideas

Written by
Alexander Fleming (1881-1955) was a Scottish biologist and pharmacologist. His primary achievement was the discovery of the enzyme lysozyme in 1922, and with the Australian researcher Howard Florey the discovery of the antibiotic, in 1928, penicillin from the fungus Penicillum notatum. For this discovery they were awarded the Nobel Prize for medicine and physiology in 1945. Fleming had studied to become a medical doctor but somehow wound up a medical researcher. This was during the era when Louis Pasteur’s germ theory of diseases was in the air. The race was on to discover germs that caused diseases and figure out…

Joseph Lister: Men of Ideas

Written by
Joseph Lister (1827-1912) was an English surgeon. His primary accomplishment is his recognition that surgeons contributed to the death of those they operated on if they did not take measures to sterilize their hands and the instruments they employed in surgery. He introduced carbolic acid (phenol) to sterilize surgical instruments and clean wounds. Essentially, Lister discovered antiseptic means of treating wounds. Lister contributed to the germ theory of diseases and helped prevent death by spreading diseases. Preventing germs from getting into wounds prevents infection and death. Sterile surgery, which Lister introduced, has done more for public health than any thing…

Louis Pasteur: Men of Ideas

Written by
Louis Pasteur (1822-1895) was a French Chemist and microbiologist. He is best known for discovering the germ theory of disease. His germ theory of diseases and consequent efforts to kill the germs that cause diseases prevent diseases. Before Pasteur’s time, folk did not understand how diseases were caused in the human body and his studies showed how germs enter the human body and cause it to malfunction. Pasteur also made the seminal discovery of how to prevent milk from rotting (caused by germs) through what is now called pasteurization (initially heating the milk to kill potential germs and then ceiling…

Gregor Mendel: Men of ideas

Written by
Gregor Mendel (1822-1884) was a German, Augustinian priest who experimented with the inheritability of the traits of peas (and later of plants, crops, and by generalization, the inheritability of human traits). He is called the father of genetic studies. His name, Mendel, is synonymous with genetic studies. Mendel cultivated pea plants and tried to mix different varieties of the pea plants to produce hybrids of them. In the process he identified key concepts in the study of genes, such as, dominant genes, recessive genes, and alleles. Clearly, plants can be hybridized. Many of the common fruits we now consume, such…

Charles Darwin: Men of Ideas

Written by
Charles Robert Darwin (1809-1882) was an English biologist. Darwin is known for his contribution of the notion of natural selection. Early in his career as a naturalist, Darwin sailed to the Galapagos Island in South America, an Island little disturbed by man, and cut off from mainland South America; animals there were left to evolve differently from their kinds on the South American mainland. Darwin observed the behavior of animals on the island and noted that they had made some changes to their kind on the mainland of South America, a place from which they were cut off. In 1859…

John Dalton: Men of Ideas

Written by
John Dalton (1766-1844) was an English Chemist. His work was largely responsible for resurrecting the discarded Greek notion that the atom is the smallest, irreducible part of elements. He therefore contributed to our modern understanding of the elements, the atomic theory, and quantum mechanics. He also made some useful contributions in understanding color blindness in people. He said: “There can scarcely be a doubt entertained respecting the reducibility of all elastic fluids of whatever kind, into liquids; and we ought not to despair of affecting it in low temperatures and by strong pressure exerted upon the unmixed gases further.” Dalton…

Robert Boyle: Men of Ideas

Written by
Robert Boyle (1627-1691) was an Irish-English chemist and physicist. He developed what is now called Boyles law in Chemistry and is generally regarded as the father of modern Chemistry. In physics Boyle discovered the role of air in the propagation of sound, the forces involved in water becoming frozen, and studied, crystals, gems, hydrostatics and colors etc. In Chemistry Boyle advanced the view that elements (atoms) are the irreducible parts of matter; he contributed to the understanding of chemical mixtures and compounds. Boyle was one of the first persons to practice Francis Bacon’s empiricism, the insistence that knowledge should be…

An Assessment of The Social Sciences

Written by
During the month of March (2008) I lived social science. I devoted every spare time I had to thinking about the major social scientists and their contributions to their field of endeavor. I am now done with that task. However, I find myself wondering whether social science really is a science or a pseudo science? In this essay, I will try to answer my own question and if, perchance, similar questions exercise your mind you could benefit from my cogitations. To answer my question we first must have some clarity as to what is science? What is science? During the…

Karl Marx: Men of Ideas

Written by
Karl Heinrich Marx (1818-1883) was a German Jew who systematized socialism and tried to make the ideology a science worthy of academic study (his book, Das Capital has academic pretensions). Karl Marx and Frederic Engels collaborated in writing the Communist Manifesto (1848), a sort of Bible for Communist revolutionaries. Marx did not see himself as utopian but an utopian (social idealist) he was, for only such a person would disregard human nature and say: “from each according to his abilities and to each according to his needs”. That is to say that all people should work together, each using his…
