Archibald Vivian Hill: Pioneer of Muscle Physiology and Advocate for Human Rights

Archibald Vivian Hill (1886–1977), born in Bristol, England, was a trailblazer in muscle physiology and biophysics. His groundbreaking research into the mechanisms of muscle contraction and energy metabolism garnered him the Nobel Prize in Physiology or Medicine in 1922, an honor he shared with Otto Meyerhof. Hill's concept of "oxygen debt" remains foundational in understanding the physiological processes underlying physical activity.

Hill's academic foundation was laid at Trinity College, Cambridge, where he initially studied mathematics before gravitating toward physiology. His mathematical background allowed him to apply quantitative methods to physiological problems, a novel approach at the time. During World War I, he contributed significantly to the war effort by enhancing anti-aircraft targeting systems and studying the effects of physical exertion on soldiers, paving the way for modern exercise physiology.

After the war, Hill's work at University College London further advanced the understanding of muscle function. His experiments elucidated how heat production in muscles corresponds to energy release during contraction, and he clarified the role of lactic acid in muscle fatigue. These discoveries bridged the gap between biophysics and biochemistry, influencing both scientific research and practical applications in sports medicine.

Hill's influence extended beyond the laboratory. A staunch humanitarian, he opposed the Nazi regime, using his position to aid persecuted scientists, including physicist Max Born. Hill played a key role in the Academic Assistance Council (now the Council for At-Risk Academics), helping refugee scholars find safety and academic positions abroad.

As a teacher, Hill inspired countless students, emphasizing critical thinking and scientific rigor. His interdisciplinary approach continues to shape modern physiology, with the fields of biophysics and sports science building on his foundational work.

Hill's legacy endures as a testament to the power of science not only to advance knowledge but also to champion human rights and social justice. His contributions to physiology and his unwavering commitment to aiding others ensure his place as a pivotal figure in both science and society.

Alan Turing: Father of modern computing

Alan Turing, the founder of Computer Science, a mathematician, philosopher, code-breaker, was an extraordinary visionary of his time. His invention, the Universal Turing Machine laid the foundation for today’s digital computers.

Alan Mathison Turing was on 23 June 1912 in an upper-middle class British family in Paddington, London. At the age of 14, Turing was sent to Sherborne School in Dorset, southern England, a traditional British public school.

Turing went on to study mathematics at King’s College, Cambridge, from 1931 to 1934, graduating with a first-class degree. In his seminal 1936 paper, he proved that there cannot exist any universal algorithmic method of determining truth in mathematics, and that mathematics will always contain undecidable propositions.

From 1936 to 1938, Turing studied under the American mathematician Alonzo Church at Princeton University, obtaining his doctorate in a remarkably short period. After receiving his Ph.D. he returned to Cambridge, and then took a part-time position with the Government Code and Cypher School, a British code-breaking organization.

During the Second World War, Turing worked at Bletchley Park. It was the Britain’s code-breaking center where the brightest minds in the country including Gordon Welchman and Harold Keen collaborating to crack German ciphers.

In 1945, Turing went on to start the design of a stored-program electronic computer called the Automatic Computing Engine – or ACE. The name was in homage to the 19th-century computing pioneer Charles Babbage who proposed large mechanical calculating ‘engines’.

In 1948, Turing joined the Mathematics Department at the University of Manchester. He was appointed the deputy director of the computing laboratory at the university, working on software for the Manchester Mark 1, an early stored program computer. Turing continued to consider more theoretical and abstract ideas, including the concept now known as artificial intelligence, in which he explored whether a machine can think.

On 8 June 1954, Turing was found at home by his cleaner, the day after his death.

Robert Boyle: Anglo-Irish natural philosopher, chemist, physicist, and inventor

Robert Boyle (25 January, 1627 – 31 December, 1691), ‘The Father of Chemistry’, was the most influential scientist ever born in Ireland.

Robert Boyle was born in Lismore, Co. Waterford, the youngest son of Richard Boyle, First Earl of Cork, and his second wife Katherine Fenton. Richard accumulated a great fortune in Ireland and enjoyed a high social standing. Robert displayed a quiet scholarly disposition and was his father’s favorite son.

After early education at home, Robert together with his brother were sent for a while to Eton College in England for four years. Then at the age of 11 he was sent, with a French Protestant tutor, on a grand tour of Europe which lasted for 6 years.

After spending some time on the Continent, during which he met Galileo in Florence in 1641–1642, he returned to England and lived in London. In 1649 he set up a scientific laboratory, and he began to write accounts of his scientific work, promulgating the use of experiment and the scientific method.

His research intensified after 1654, when he took lodgings in Oxford, UK. There, he met regularly with another group of experimentalists convened by the mathematician John Wilkins. Its members included the multi-talented Christopher Wren and Boyle’s gifted assistant, Robert Hooke. Robert Hooke helped him in his experiments. Boyle referred to the group as the “invisible college.” This later became the Royal Society in 1662.

Boyle demonstrated the necessity of air for combustion, for animal breathing, and for the transmission of sound.

Using an improved air pump built for him by Hooke, Boyle began to study the physics of gases. The results appeared in 1660 as New Experiments Physico-mechanical Touching the Spring of the Air and its Effects, in which he described the first controlled experiments of the effects of reducing the pressure of the air. Soon afterwards, he stated for the first time the inverse relationship between gas pressure and volume we now call ‘Boyle’s law’.

Caroline Herschel: The first female comet-hunter

Herschel, Caroline Lucretia (16 March 1750 – 9 January 1848), astronomer, was born at Hanover, the eighth child and fourth daughter of Isaac Herschel (1707–1767) and his wife, Anna Ilse Moritzen.

The Herschels grew up in a musical family in Hanover, and there Caroline was trained to look after her brothers and ageing parents. Her father also encouraged his children to study music, Mathematics and French.

Closer to her father, Caroline recounted that one of her strongest childhood memories was of her father taking her outside on a frosty night and showing her the winter stars 'to make me acquainted with the most beautiful constellations, after we had been gazing at a comet which was then visible'.

Caroline's childhood was overshadowed by the defeat in 1757 of the Hanoverian army by the French in the Seven Years' War and the resulting occupation of Hanover. Her elder brother William, though in the same band as their father, was too young to be under oath, and so was free to flee to England. Caroline joined her brother, William in England in 1772, ostensibly to train as a singer and to accompany him in his concerts. This training was technical in nature, teaching her the mechanics of how to sing and make her voice carry, how to read music and speak English.

William and Caroline often discuss astronomy. Eventually her interest grew in that area and she gave up a promising career as a singer to concentrate on astronomy. Her brother soon found her efficient, meticulously talents essential to his work. She assisted him by his recording his observation astronomical catalogue.

Then in 1781 William discovered the planet Uranus and this gained him a Royal Pension from George III, with the requirement that they should give up music and move near to Windsor Castle. Once there, Caroline began training as an astronomer, learning skills she was expected to put to use almost immediately, acting as her brother’s astronomical assistant and scribe.William had built her a telescope expressly designed for the discovery of comets.

Caroline was to become famous as the discoverer, or co-discoverer, of no fewer than eight comets, four with the sweeper made in 1783, three with its successor, and the last, found in 1797, with the naked eye. However, her earliest sweeps, in the winter of 1782–3, yielded not comets but comet-like nebulae, to add to the hundred or so already known. Later in 1783 she was to discover the companion to the Andromeda nebula.

When William died in 1822, Caroline returned home to Germany and continued her astronomical work. She was awarded a gold medal by the Royal Astronomical Society in 1828 and was made an honorary member of the Royal Society ten years later.

Michael Faraday (22 September 1791 – 25 August 1867): British physicist and chemist

Michael Faraday was born in 1791 in the village of Newington, now part of the urban area of London. His father was a blacksmith who had migrated from the north of England earlier in 1791 to look for work and his family was able to allow him but the most basic education.

He was hired in a London bookshop, run by Mr. George Riebau. This work enabled Michael Faraday to read many books, that passed through the bookshop of Mr. Riebau. In his spare time he was an avid reader, teaching himself many scientific concepts.

With the help of a customer of the shop, in 1812 Faraday was able to attend the public lectures of one of the most famous scientists of the day, the chemist Humphry Davy, director of the Royal Society. For our Michael it was a veritable godsend, and perhaps precisely for this reason, also thanks to his curiosity and his initiative, he was able to exploit this opportunity more than anyone else.

In 1813 he was appointed as Chemical Assistant at the Royal Institution. During his stay at the Royal Institution, Faraday managed to obtain the two fundamental laws of electrolysis.

*First LAW: For a given solution, the quantity of matter that is deposited on the electrodes is proportional to the amount of charge which passes through the solution. This implies that the ions carrying the charge through the solution have a well-defined electric charge.

*Second LAW: The monovalent ions of different sub-stances carry an equal quantity of electric charge, while the bi- or tri-valent ones carry a correspondingly higher charge.

Faraday, who became one of the greatest scientists of the 19th century, began his career as a chemist. He wrote a manual of practical chemistry that reveals his mastery of the technical aspects of his art, discovered a number of new organic compounds, among them benzene, and was the first to liquefy a “permanent” gas.

His major contribution, however, was in the field of electricity and magnetism. He was the first to produce an electric current from a magnetic field, invented the first electric motor and dynamo, demonstrated the relation between electricity and chemical bonding, discovered the effect of magnetism on light, and discovered and named diamagnetism, the peculiar behaviour of certain substances in strong magnetic fields.

Faraday was the author of numerous publications in scientific journals. his main contributions are collected in his Laboratory Journal, which he hold regularly from 1820 until 1862.

History of Faraday’s scientific discoveries·
*1810-1820 First Electrochemical Experiments·

Biography of Robert Hooke

Microscopes existed in Holland by 1620. Robert Hooke and Christian Huygens were the first two scientists to make scientific use of microscope. Both designed and built two lens microscopes.

English scientist Robert Hooke (28 July 1635 – 3 March 1703) was one of the most important early chemists because his contributions would prove crucial to the birth of modern forensic science. Among many other achievements, Robert Hooke did significant development with microscopes, the first forensic instrument.

Robert Hooke also made significant theoretical and practical contributions many fields of science, including astronomy, mechanics, chemistry and physiology, geology, optics, psychology, music theory, microscopy and horology. He also did much architectural work, assisting in the rebuilding of London after the Great Fire of 1666.

In 1660, Robert Hooke investigated the phenomenon of color separation on thin transparent films, such as the colorful soap bubble. This study provided him with the rudimentary theoretically conviction that light is a wave.

In 1665, Robert Hooke proposed that atomic model of matter, based on crystalline structure and apparent transparence, indicating holes between the solid-state natures.

Joseph Lister - a pioneer of antiseptic surgery

Joseph Lister (5 April 1827 – 10 February 1912) was born to a prosperous family at Upton, Essex England. He was one of seven children, all of whom lived to adulthood. His father, the prominent Quaker Joseph Jackson Lister, perfected the achromatic lens and participated in the Royal Society.

Joseph interested himself in the world of the microscopic and he was excellent draftsman who might have made a fine artist.

He was taught at a private school and at London University which he began to attend in 1843 at age sixteen. Lister initially entered the arts faculty, graduating with Bachelor of Arts degree in 1847. Lister received his degrees in medicine and surgery in 1852.

He was appointed assistant surgeon to the Royal Infirmary, and extra-academical lecturer on surgery. In 1856 he was appointed regius professor of surgery in the University of Glasgow. He held this post for 4 years, during which he lectured on surgery.

His first papers, published in 1853, while he was still a student, were on the muscular tissue of the skin, and the contractible tissue of the iris. His article on Antisepsis, entitled “On a New Method of Treating Compound Fracture Abscess, Etc.” appeared in the Lancet in 1867.

Lister retired from practice in 1896 but continued his scientific work. In the next year he was elected President of the Royal Society.
