Biography of Julius Nyerere

Written by
Julius Kambarage Nyerere (April 13, 1922 - October 14, 1999) was President of Tanzania (previously Tanganyika), from the country's founding in 1964, until his retirement in 1985. Born in Tanganyika to a local Zanaki chief called Nyerere Burito, Julius Nyerere was known by the Swahili name Mwalimu, or "teacher," because of his profession before becoming active in politics. Nyerere was the first African head of state to retire voluntarily. He stepped down because he realized that his socialist policies of communal ownership of farms and state ownership of services were not working. Under his Presidency, Tanzania slipped from being the…

John Logie Baird: Men of Ideas

Written by
John Logie Baird (1888-1946) was a Scottish inventor who played a key role in the invention of the Television. Whereas there is some dispute as to who actually invented the TV, the British have no doubt as to who did so, Baird did. Baird is credited with being the first person to produce a live moving image on television in halftones by reflected light. Baird demonstrated his television and its live moving images in 1925, at a London Department Store. He demonstrated the world’s first color transmission in 1926. In 1927 Baird demonstrated long distance transmission of television between London…
Robert Goddard (1882-1945) was an American physicist and engineer who pioneered controlled liquid fueled rocketry. He launched the first liquid fueled rocket in 1926. He is the father of modern rocketry. Our age has sent a man to the moon and is currently exploring space thanks to Goddard’s efforts in understanding rockets and launching them. Clearly, Goddard was a man ahead of his times. In the 1920s and 1930s when he was attempting to manufacture and launch rockets the general public was not aware of what rockets were and few were interested in rockets. It was only during the Second…

George Washington Carver: Men of Ideas

Written by
George Washington Carver (1864-1943) was an African-American agronomist who made contributions to scientific farming in the Southern United States. He provided agricultural extension studies to farmers thereby enabling them to apply scientific farming methods to their farming practices hence improving their crop yields. For example, planting cotton over and over on the same soil depletes the soil’s nutrients whereas rotating different crops (say, peanuts) and cotton on the soil improved the quality of the soil. Carver taught farmers to rotate their crops on the same soil. Many claims were made regarding Carver’s findings and inventions, for example, on how peanuts…

George Stephenson: Men of Ideas

Written by
George Stephenson (1781-1848) was an English mechanical engineer. He built the first public railway line in the world, using steam locomotives. He is considered the father of Railways. Stephenson did not invent the first locomotive engine; that credit goes to Richard Trevithick who in 1804 rigged such engines to help pull coal out of coal mines. Stephenson’s first locomotive engine, designed in 1814, was also for hauling coal out of coal mines (Killingworth wagon way, and named Blucher after the German whose blueprint for the design he said influenced his design). What made Stephenson famous was constructing an eight mile…

James Watts: Men of Ideas

Written by
James Watts (1736-1819) was a Scottish inventor. He made improvements on the steam engine, improvements that laid the foundation for the industrial revolution and ushered in our age. Watt did not discover the steam engine, others before him did, but he figured out a way to incorporate latent heat in running engines. He not only improved steam engines but also mass produced them thereby making them readily available to those who desired them. His engines were used for pumps and produced reciprocating motion. With encouragement from Boulton, Watt improved his engine further and found a way to convert the reciprocating…

Johannes Guttenberg: Men of Ideas

Written by
Johannes Guttenberg (1400-1468) was a German goldsmith credited with inventing the metal moveable type printing. Although such printing type may have existed in China for several centuries, Guttenberg was the first in the Western world to make it possible. In so doing he made it possible to mass produce books. Prior to him books, mostly Bibles, were laboriously hand written and reproduced by hand. Making books easily and cheaply produced meant that people with ideas could now print their ideas and sell them and that way spread alternative ideas than was taught by the Catholic Church. In a manner of…
Francis Crick (1916-2004) was an English molecular biologist. James D Watson (1928- ) is an American molecular biologist. Crick and Watson are noted for been the co-discoverers of DNA in 1953, for which they won the Nobel Prize in Biology in 1963. According to his biography, Crick was interested in how molecules make the transition from non-living to living things and how the brain makes the conscious mind. Apparently, he succeed in the former and failed in understanding the later, for no one has understood how the brain makes consciousness, mind. Crick and Watson worked hard and eventually showed how…

Paul Dirac: Men of Ideas

Written by
Paul Dirac (1902-1984) was a British theoretical physicist. He made seminal contributions to Quantum Mechanics. Dirac was noted for formulating what is now called Dirac equation, which describes the behavior of fermions and which led to the prediction of the existence of anti matter. For this discovery he was awarded the 1933 Nobel Prize in Physics (along with Erwin Schrödinger). Dirac built on Pauli’s non-relativistic spin systems to propose what is now called Dirac equation, a relativistic equation of motion for the wave function of the electron. His equation led him to predict the existence of an anti electron particle,…

Edwin Hubble: Men of Ideas

Written by
Edwin Hubble (1889-1953) was an American astronomer. With his telescope, Hubble demonstrated the existence of other galaxies other than our own, the Milky Way, and in so doing profoundly changed our understanding of the universe. He showed the immensity of the universe, now calculated to be over thirteen billion light years across. Hubble showed that the universe is expanding. Finally, he showed that light coming from other galaxies, redshift, increased in proportion to the distance of that galaxy from the Milky Way. Hubble’s discoveries consist of the fact that there is more than one galaxy. During his time, early part…

Louis Broglie: Men of Ideas

Written by
Louis Broglie (1892-1987) was a French physicist. In his 1922 doctoral thesis he introduced the theory of electron waves. He developed this idea into what is now called Broglie hypothesis, which states that any moving particle or object has an associated wave (that is, moving matter has both particular and wave function). In effect, Broglie united the wave and particle functions of particles. He further united the physics of light and matter by showing that the wave-particular function is applicable to all matter, not just light. For this discovery he won the Nobel Prize in Physics in 1929. Broglie’s work…

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…
