Death of Thomas Andrews, Chemist & Physicist

thomas-andrews

Thomas Andrews, chemist and physicist who does important work on phase transitions between gases and liquids, dies in Belfast on November 26, 1885. He is a longtime professor of chemistry at Queen’s University Belfast.

Andrews is born in Belfast on December 19, 1813, where his father is a linen merchant. He attends the Belfast Academy and the Royal Belfast Academical Institution, where at the latter of which he studies mathematics under James Thomson. In 1828 he goes to the University of Glasgow to study chemistry under Professor Thomas Thomson, then studies at Trinity College, Dublin, where he gains distinction in classics as well as in science. Finally, at the University of Edinburgh in 1835, he is awarded a doctorate in medicine.

Andrews begins a successful medical practice in his native Belfast in 1835, also giving instruction in chemistry at the Royal Belfast Academical Institution. In 1842, he marries Jane Hardie Walker. They have six children, including the geologist, Mary Andrews.

Andrews first becomes known as a scientific investigator with his work on the heat developed in chemical actions, for which the Royal Society awards him a Royal Medal in 1844. Another important investigation, undertaken in collaboration with Peter Guthrie Tait, is devoted to ozone. In 1845 he is appointed vice-president and professor of chemistry of the newly established Queen’s University Belfast. He holds these two offices until his retirement in 1879 at the age of 66.

His reputation mainly rests on his work with liquefaction of gases. In the 1860s he carries out a very complete inquiry into the gas laws — expressing the relations of pressure, temperature, and volume in carbon dioxide. In particular, he establishes the concepts of critical temperature and critical pressure, showing that a substance passes from vapor to liquid state without any breach of continuity.

In Andrews’ experiments on phase transitions, he shows that carbon dioxide may be carried from any of the states we usually call liquid to any of those we usually call gas, without losing homogeneity. The mathematical physicist Josiah Willard Gibbs cites these results in support of the Gibbs free energy equation. They also set off a race among researchers to liquify various other gases. In 1877-78 Louis Paul Cailletet is the first to liquefy oxygen and nitrogen.

Thomas Andrews dies in Belfast on November 26, 1885, and is buried in the city’s Borough Cemetery.

Birth of Physicist John Joly

John Joly, Irish physicist famous for his development of radiation therapy in the treatment of cancer, is born in Bracknagh, County Offaly, on November 1, 1857. He is also known for developing techniques to accurately estimate the age of a geological period, based on radioactive elements present in minerals.

Joly is a second cousin of Charles Jasper Joly, the astronomer. He enters Trinity College, Dublin in 1876, graduating in Engineering in 1882 in first place with various special certificates in branches of engineering, at the same time obtaining a First-Class Honours in modern literature. He works as a demonstrator in Trinity’s Engineering and Physics departments before succeeding William Johnson Sollas in the Chair of Geology and Mineralogy in 1897, a position which he holds until his death in 1933.

Joly joins the Royal Dublin Society in 1881 while still a student and is a frequent contributor of papers. During his career he writes over 270 books and scientific papers.

On May 17, 1899, Joly reads his paper “An Estimate of the Geological Age of the Earth” to the Royal Dublin Society. In it, he proposes to calculate the age of the earth from the accumulation of sodium in the waters of the oceans. He calculates the rate at which the oceans should have accumulated sodium from erosion processes and determines that the oceans are about 80 to 100 million years old. The paper is quickly published, appearing four months later in the Society’s Scientific Transactions. Although this method is later considered inaccurate and is consequently superseded, it radically modifies the results of other methods in use at the time.

In 1903 he publishes an article in Nature in which he discusses the possibility of using radium to date the Earth and goes on to study the radioactive content of the Earth’s crust to formulate a theory of thermal cycles and examines the radioactive constituents of certain rocks as a means of calculating their age. Working in collaboration with Sir Ernest Rutherford, he uses radioactive decay in minerals to estimate, in 1913, that the beginning of the Devonian period could not be less than 400 million years ago, an estimate which is in line with modern calculations.

Joly serves as President of Section C (Geology) when the British Association for the Advancement of Science meets in Dublin in 1908, during which he presents his paper “Uranium and Geology” in an address to the society. This work describes radioactive materials in rocks and their part in the generation of the Earth’s internal heat.

Along with his friend Henry Horatio Dixon, Joly also puts forward the cohesion-tension theory which is now thought to be the main mechanism for the upward movement of water in plants.

In 1914 Joly develops a method of extracting radium and applies it in the treatment of cancer. As a Governor of Dr. Steevens’ Hospital in Dublin, in collaboration with Walter Stevenson, he devises radiation therapy methods and promotes the establishment by the Royal Dublin Society of the Irish Radium Institute where they pioneer the “Dublin method” of using a hollow needle for deep radiation therapy, a technique that later enters worldwide use. The Radium Institute also supplies capillary tubes containing radon to hospitals for some years for use in the treatment of tumours.

Joly is elected a Fellow of the Royal Society of London in 1892, is awarded the Boyle Medal of the Royal Dublin Society in 1911, the Royal Medal of the Royal Society of London in 1910, and the Murchison Medal of the Geological Society of London in 1923. He is also conferred honorary degrees by the National University of Ireland, the University of Cambridge, and the University of Michigan. After his death in 1933, his friends subscribe the sum of £1,700 to set up a memorial fund which is still used to promote the annual Joly Memorial Lectures at the University of Dublin, which were inaugurated by Sir Ernest Rutherford in 1935. He is also remembered by the Joly Geological Society, a student geological association established in 1960.

In 1973 a crater on Mars is named in Joly’s honour.

Birth of Charles Boyle, 4th Earl of Orrery

Charles Boyle, 4th Earl of Orrery, English nobleman, statesman and patron of the sciences, is born in Little Chelsea, London on July 28, 1674.

Boyle is the second son of Roger Boyle, 2nd Earl of Orrery, and his wife Lady Mary Sackville, daughter of Richard Sackville, 5th Earl of Dorset. He is educated at Christ Church, Oxford, and soon distinguishes himself by his learning and abilities. Like the first earl, he is an author, soldier and statesman. He translates Plutarch‘s life of Lysander, and publishes an edition of the epistles of Phalaris, which engages him in the famous controversy with Richard Bentley. He is a member of the Parliament of Ireland and sits for the Charleville constituency between 1695 and 1699. He is three times member for the town of Huntingdon and, upon the death of his brother, Lionel, 3rd earl, in 1703, he succeeds to the title.

Boyle enters the army, and in 1709 is raised to the rank of major-general and sworn one of Her Majesty’s Privy Council. He is appointed to the Order of the Thistle and appointed queen’s envoy to the states of Brabant and Flanders. Having discharged this trust with ability, he is created an English peer, as Baron Boyle of Marston, in Somerset. He inherits the estate in 1714.

Boyle becomes a Fellow of the Royal Society in 1706. In 1713, under the patronage of Boyle, clockmaker George Graham creates the first mechanical solar system model that can demonstrate proportional motion of the planets around the Sun. The device is named the orrery in the Earl’s honour.

Boyle receives several additional honours in the reign of George I but, having had the misfortune to fall under the suspicion of the government for playing a part in the Jacobite Atterbury Plot, he is committed to the Tower of London in 1722, where he remains six months, and is then admitted to bail. On a subsequent inquiry he is discharged.

Boyle writes a comedy, As you find it, printed in 1703 and later publishes together with the plays of the first earl. In 1728, he is listed as one of the subscribers to the Cyclopaedia of Ephraim Chambers.

Charles Boyle dies at his home in Westminster on August 28, 1731 and is buried in Westminster Abbey. He bequeaths his personal library and collection of scientific instruments to Christ Church Library. The instruments are now on display in the Museum of the History of Science, Oxford.

Boyle’s son John, the 5th Earl of Orrery, succeeds to the earldom of Cork on the failure of the elder branch of the Boyle family, as earl of Cork and Orrery.

Death of Robert Mallet, the Father of Seismology

robert-mallet

Robert Mallet, geophysicist, civil engineer, and inventor who distinguishes himself in research on earthquakes and is sometimes called the Father of Seismology, dies on November 5, 1881.

Mallet is born in Dublin on June 3, 1810, the son of factory owner John Mallet. He is educated at Trinity College, Dublin, entering it at the age of 16 and graduating in science and mathematics in 1830 at the age of 20.

Following his graduation, he joins his father’s iron foundry business and helps build the firm into one of the most important engineering works in Ireland, supplying ironwork for railway companies, the Fastnet Rock lighthouse, and a swing bridge over the River Shannon at Athlone. He also helps manufacture the characteristic iron railings that surround Trinity College, and which bear his family name at the base.

Mallet is elected to the Royal Irish Academy in 1832 at the early age of 22. He also enrolls in the British Association for the Advancement of Science in 1835 which helps finance much of his research in seismology.

In 1838 he becomes a life member of the Royal Geological Society of Ireland and serves as its President from 1846–1848. From 1848–1849 he constructs the Fastnet Rock lighthouse, southwest of Cape Clear.

On February 9, 1846, he presents to the Royal Irish Academy his paper On the Dynamics of Earthquakes, which is considered to be one of the foundations of modern seismology. He is also credited with coining the word “seismology” and other related words which he uses in his research. He also coins the term epicentre.

From 1852 to 1858, he is engaged in the preparation of his work, The Earthquake Catalogue of the British Association (1858) and carries out blasting experiments to determine the speed of seismic propagation in sand and solid rock.

On December 16, 1857, the area around Padula, Italy is devastated by the Great Neapolitan earthquake which causes 11,000 deaths. At the time it is the third largest known earthquake in the world and has been estimated to have been of magnitude 6.9 on the Richter Scale. Mallet, with letters of support from Charles Lyell and Charles Darwin, petitions the Royal Society of London and receives a grant of £150 to go to Padula and record at first hand the devastation. The resulting report is presented to the Royal Society as the Report on the Great Neapolitan Earthquake of 1857. It is a major scientific work and makes great use of the then new research tool of photography to record the devastation caused by the earthquake. In 1862, he publishes the Great Neapolitan Earthquake of 1857: The First Principles of Observational Seismology in two volumes. He brings forward evidence to show that the depth below the Earth’s surface, from where the impulse of the Neapolitan earthquake originated, is about 8–9 geographical miles.

One of Mallet’s papers is Volcanic Energy: An Attempt to develop its True Origin and Cosmical Relations, in which he seeks to show that volcanic heat may be attributed to the effects of crushing, contortion, and other disturbances in the crust of the earth. The disturbances leading to the formation of lines of fracture, more or less vertical, down which water would find its way, and if the temperature generated be sufficient volcanic eruptions of steam or lava would follow.

Mallet is elected Fellow of the Royal Society in 1854, and in 1861 moves to London, where he becomes a consulting engineer and edits The Practical Mechanic’s Journal. He is awarded the Telford Medal by the Institution of Civil Engineers in 1859, followed by the Cunningham Medal of the Royal Irish Academy for his research into the theory of earthquakes in 1862, and the Wollaston Medal of the Geological Society of London in 1877, the Geological Society’s highest award.

Blind for the last seven years of his life, Robert Mallet dies at Stockwell, London, on November 5, 1881, and is buried at West Norwood Cemetery.

Death of Mary Ward, First Motor Vehicle Fatality

mary-ward

Mary Ward, Anglo-Irish amateur scientist, is killed on August 31, 1869, when she falls under the wheels of an experimental steam car built by her cousins. As the event occurs in 1869, she is the world’s first person known to be killed by a motor vehicle.

During the 19th century, when most women have little encouragement for a science education, Mary is unusual. She is born Mary King in present-day Ferbane, County Offaly on April 27, 1827, the youngest child of Henry and Harriett King. She and her sisters are educated at home, as are most girls at the time. However, her education is slightly different from the norm because she is of a renowned scientific family. She is interested in nature from an early age, and by the time she is three years old she is collecting insects.

Universities and most societies do not accept women, but Mary obtains information any way she can. She writes frequently to scientists, asking them about papers they have published. During 1848, her cousin William Parsons, 3rd Earl of Rosse, is made President of the Royal Society, enabling her to meet many scientists during visits to his home.

Parsons’ sons build a steam-powered car. It is thought at the time that steam transport will be developed greatly during the near future. This becomes true for trains but does not become true for cars due to the development of internal combustion engine. Steam cars are heavy, and they do too much damage to the already uneven roads. In 1865, the Red Flag Acts imposes a speed limit of four miles per hour for the countryside and two miles per hour in towns. This effectively ends the popularity of motorcars, but some enthusiasts still have one, often homemade, like the Parsons’ vehicle.

On August 31, 1869, Mary and her husband, Henry, are travelling in it with the Parsons boys, Richard Clare Parsons and the future steam turbine pioneer Charles Algernon Parsons, and their tutor, Richard Biggs. She is thrown from the car on a bend in the road at Parsonstown, County Offaly. She falls under its wheel and dies almost instantly. A doctor who lives near the scene arrives within moments and finds her cut, bruised, and bleeding from the ears. The fatal injury is a broken neck.

Birth of Mathematician George Gabriel Stokes

george-gabriel-stokes

Sir George Gabriel Stokes, mathematician, physicist, politician, and theologian, is born into an evangelical Protestant family in Skreen, County Sligo, on August 13, 1819. After attending schools in Skreen, Dublin, and Bristol, he matriculates in 1837 at Pembroke College, Cambridge.

In 1849, Stokes is appointed to the Lucasian professorship of mathematics at Cambridge, a position he holds until his death in 1903. In physics, Stokes makes seminal contributions to fluid dynamics, including the Navier–Stokes equations, and to physical optics. In mathematics he formulates the first version of what is now known as Stokes’ theorem and contributes to the theory of asymptotic expansions.

On June 1, 1899, the jubilee of his appointment is celebrated in a ceremony which is attended by numerous delegates from European and American universities. A commemorative gold medal is presented to Stokes by the chancellor of the university, and marble busts of Stokes by Hamo Thornycroft are formally offered to Pembroke College and to the university by Lord Kelvin.

Stokes, who is made a baronet in 1889, further serves his university by representing it in parliament from 1887 to 1892 as one of the two members for the Cambridge University constituency. During a portion of this period (1885–1890) he also serves as president of the Royal Society, of which he has been one of the secretaries since 1854. Since he is also Lucasian Professor at this time, Stokes is the first person to hold all three positions simultaneously.

Stokes dies on Feb. 1, 1903, at his cottage in Cambridge, Cambridgeshire, England. He is buried in the Mill Road Cemetery.
