The Moon Landing and Sir William Rowan Hamilton

Space exploration would be unthinkable without the contribution of the Trinity College graduate, mathematician, poet and Professor of Astronomy William Rowan Hamilton (1805-1865), best known as the inventor of quaternions. Quaternions provide a mathematical notation for representing orientations and rotations of objects in three dimensions – essential for space flight. They are routinely employed by NASA, and were used in simulations and in plotting the orbit of the missions to the moon. These equations are also used in many other established and emerging technologies, from the computer games industry to molecular dynamics.

Among the Library’s manuscript collections is the tiny notebook which contains Hamilton’s earliest surviving workings-out of the quaternion equation. As he recounted to Peter Guthrie Tait in a letter of 15 October 1858, ‘[I] felt the galvanic circuit of thought close; and the sparks which fell from it were the fundamental equations between i, j, k; exactly such as I have used them ever since. I pulled out on the spot a pocket-book, which still exists, and made an entry’.

The first ‘written’ recording of the quaternion equation was a piece of graffiti scratched by Hamilton on Broome Bridge in Dublin. In a letter to his son, Hamilton recalled the circumstances around his ‘discovery’ on 16 October 1843, ‘which happened to be a Monday, and a council day of the Royal Irish Academy – I was walking in to attend and preside, and your mother was walking with me, along the Royal Canal…yet an under-current of thought was going on in my mind, which gave at last a result, whereof it is not too much to say that I felt at once the importance … nor could I resist – unphilosophical as it may have been – to cut with a knife on a stone of Brougham Bridge, as we passed it, the fundamental formula … but of course, as an inscription, has long since mouldered away’.

Although the inscription degraded within Hamilton’s lifetime the site is now commemorated with a plaque. 

Mathematicians and scientists from around the world (some with NASA connections) have made pilgrimages to see the little notebook in the Manuscripts & Archives Reading Room. The manuscript was also filmed for tomorrow’s RTE broadcast ‘The day we landed on the Moon’, where Professor Peter Gallagher, Adjunct Professor of Astrophysics at Trinity and Head of Astronomy and Astrophysics at DIAS, will explain the direct relationship with the Apollo missions.

Hamilton’s significance for the moon landing itself was recognised by Neil Armstrong when he visited the Library of Trinity College Dublin a few years ago. Whilst being shown around the Old Library he stopped at the marble bust of Sir William Rowan Hamilton and discussed the role of such calculations in the control of spacecraft.

The Dublin Apocalypse

The Library is digitising apocalypse manuscripts like there’s no tomorrow. The Dublin Apocalypse (TCD MS 64) contains the Latin text of the Book of Revelation, heavily decorated with 73 vibrant miniatures, and you can now see the Final Judgement in gold and vivid colour on our Digital Collections.

IE TCD MS 64, folio 31r

The imaging of this volume was completed to coincide with a one-day symposium based on the Dublin Apocalypse, taking place in the Neill Lecture Theatre of the Trinity Long Room Hub on Friday, 1 February 2019 from 9.45am. The event will draw together experts in their fields to discuss multiple aspects of the Dublin Apocalypse and its broader context. Attendance at what is sure to be an fascinating event is free but registration is essential at https://dublinapocalypse.eventbrite.ie.

IE TCD MS 64, folio 6r

Nigel Morgan, Professor Emeritus of the University of Cambridge, will discuss the iconography of the manuscript through an art historical lens. Michael Michael’s and Frederica Law-Turner’s papers will cast light on the Ormesby Psalter and delve into the East Anglian school of manuscripts. James T. Palmer, of the University of St Andrews, will study the circulation, interpretation, and use of the Book of Revelation in the Middle Ages.  

Bernard Meehan, former Head of Research Collections and Keeper of Manuscripts at the Library of Trinity College Dublin will recount the curious story of how the manuscript arrived at the College through an unusual deal between the Board and a former Provost. Finally, Laura Cleaver, Ussher Lecturer in Medieval Art in Trinity, will address early-twentieth century facsimiles of the text and their impact. 

So, if you’re seeking a friend for the end of the world or simply interested in one of the Library’s medieval treasures, please join us for insightful discussion and some free coffee.

Illuminating the Middle Ages

The Library is home to a unique collection of around 450 medieval Latin manuscripts, spanning a period of 800 years. Until now, the catalogue has existed solely in hard copy but it has been taken from the shelves of the reading room and made globally accessible online through our Manuscripts and Archives online catalogue, available here. You can search specific manuscripts by title, reference number or any keyword relevant to your area of interest – or simply search for the phrase ‘medieval manuscripts’ to have a browse.

TCD MS 52, folio 32v

The most effective way to illustrate the scope of this project is to provide some insight into the array of items that come under the umbrella of Trinity’s Latin manuscript collection. Perhaps the most well-known group consists of seven Early Irish Christian manuscripts dating from Ireland’s golden age of faith and culture. Among the seven are the Book of Armagh (TCD MS 52) and the Book of Kells (TCD MS 58), which are among the most famous manuscripts in Ireland and, in the case of the latter, the world. All seven of these manuscripts have now been conserved, fully imaged and are available freely online through the Library’s Digital Collections.

The medieval collection includes luxuriously illuminated Books of Hours, confessors’ handbooks, psalters and bibles, to name but a few. The Book of Kells may be the most magnificently decorated Insular manuscript in existence but does it have a plate-spinning dog? No.

TCD MS 35, folio 17v

TCD MS 632 presents a kind of fifteenth-century classical handbook for medieval readers. Through articles, diagrams and maps, the book accounts for multiple aspects of classical study including mythology, geography and history. These small circular diagrams represent the rivers of the classical world. The larger infographic here relates to the length of time it takes individual planets to orbit the earth (the word terra is marked in the centre). The seven zones of the earth (including the arctic and temperate) are illustrated on folio 108r, identifying which zones are habitable and which are not. There is also a brief note beneath the diagram referring to the nine Muses of Greek mythology.

TCD MS 632, folios 107v-108r

TCD MS 10994, folio 1r

This charming fellow situated inside the large letter Q of TCD MS 10994, likely depicts Michael of Belluno in Italy; the named scribe of this manuscript. The text serves as a guide for confessors, a list of sins and omissions committed by society, including (but not limited to) boasting, dancing, fighting, superfluous drinking, cursing, gluttons who eat too quickly, men in curled wigs, women who indulge in cosmetics and listening to arousing music.

Other standout examples include the Ricemarch psalter, a Latin text of Welsh origin in an Irish style, and the Dublin Apocalypse (TCD MS 64, pictured below), a fourteenth-century manuscript depicting the Final Judgement in gold and vivid colour that is simultaneously beautiful and grotesque. This particular illustration is the horseman of war, identifiable by his fiery red horse and his big ol’ sword.

If you would like to learn more, here is a quick and shameless plug for our Illuminating the Middle Ages online exhibition which went live in January of this year, available at the following link.

What is Life? Celebrating Erwin Schrödinger and the science collections in the Library of Trinity College Dublin

In 1943, Erwin Schrödinger (1887-1961), Nobel-prize winning physicist and Director of Dublin Institute for Advanced Studies (DIAS), delivered three public lectures entitled What is Life? at Trinity College Dublin as the DIAS statutory lecture. The lectures were published as a book in 1944 and had an immediate and powerful impact on the development of molecular biology including inspiring the discovery of DNA.

To mark the anniversary, and to coincide with the major international conference ‘What is Life?’ Schrӧdinger at 75 – the Future of Biology, Archivist Estelle Gittins has collaborated with Professor Luke O’Neill, one of the conference organisers, to curate an exhibition now on show in the Old Library of Trinity College Dublin. The exhibition, and accompanying online exhibition, showcase some of the Library’s most significant scientific and mathematical collections.

At the outbreak of World War II, Schrӧdinger was invited to Dublin by President Éamon de Valera to become Director of the School of Theoretical Physics at Dublin Institute of Advanced Studies, where he stayed until 1956. The exhibition examines what attracted him to Dublin; one of the reasons was the chance to walk in the footsteps of one of his heroes, Ireland’s most renowned scientist Sir William Rowan Hamilton (1805-1865).

Hamilton made numerous advances in maths and science reflected in the vast collection of his papers held in the Library, but he is most famous for developing Quaternions, the mathematical notation for representing orientations and rotations of objects in three dimensions. Quaternions are essential for calculating orbital rotation in space flight; they are routinely employed by NASA, and are also relied upon by the computer gaming industry. The exhibition includes the tiny notebook containing Hamilton’s first scribbled recording of the Quaternion equation made as he walked by the Royal Canal at Broome Bridge in Dublin. The display also includes poetry and sketches that provide a glimpse of the private man as well as the genius. Schrödinger has been described as the scientific heir to Hamilton and made use of the Hamiltonian operator in his wave equation.

Whilst in Dublin, the sociable Schrödinger joined a circle of intellectuals sheltering in neutral Ireland including Irish physicists Shelia Power and Kathleen Lonsdale who had returned from Edinburgh and London respectively. The exhibition includes the papers of some of those friends and colleagues, including a first edition of What is life? inscribed by Schrödinger for his close friend and Trinity College Provost Albert McConnell (1903-1993). Schrödinger also spent time with fellow Nobel-prize winner, Ernest Walton (1903-1995). Walton, a Trinity graduate and lecturer, is most famous, (along with John Cockcroft), for the splitting of the atom in 1932, which constituted the physical demonstration of Einstein’s law E=mc. On display is Walton’s first communication of the breakthrough, an understated letter to his fiancée Freda Wilson confiding, ‘Cockcroft and I made what is in all probability a very important discovery in the lab … It opens up a whole new field of work which may go a long way towards elucidating the structure of the nucleus of the atom’. This is displayed alongside Walton’s Nobel medal. Ernest Walton very generously donated his scientific and personal papers to the Library in 1993.

The exhibition also looks at the important academic and cultural legacy of the What is life? lecture series including the 40th anniversary commemorations where an older Professor Walton met a younger Professor Hawking. There is also a selection of the literary and artistic works inspired by the notion of ‘Schrödinger as a Dubliner’ such as the musical Improbable Frequency produced by the Rough Magic Theatre Company, whose own archives were donated to the Library in 2017.

The conference Schrödinger at 75: the future of Biology will be streamed live on the website https://www.tcd.ie/biosciences/whatislife/

The exhibition What is Life? Celebrating Erwin Schrödinger and the science collections in the Library of Trinity College Dublin will be on display in the Long Room of the Old Library until 31 October and the online version can be accessed here http://www.tcd.ie/library/exhibitions/what-is-life/

Davitt Down Under

Michael Davitt, who was born in 1846 and died in 1906, was a radical Irish nationalist, social reformer and champion of the Irish diaspora of the nineteenth and twentieth centuries. Davitt’s papers are held in the Manuscripts’ Department of the Library of Trinity College Dublin. The photographs within the collection are in the process of being catalogued and digitised.

In 1895, Michael Davitt departed Dublin for a tour of Australia, New Zealand, Samoa, Hawaii and the United States.

One of the aims of the tour was to re-connect with the Irish communities in Australia after Charles Stewart Parnell’s adulterous relationship with Kitty O’Shea became public knowledge and caused major damage to the Irish Parliamentary Party’s (IPP) reputation internationally.

Irish-Australians had been major financial contributors to Irish famine relief, the IPP and the Land League throughout the nineteenth century. Their support was essential for continuing the campaign towards Irish Home Rule in Westminster. Other reasons for the tour were personal; including Davitt’s need to make money for his family by lecturing in Australia and New Zealand.

MS 9477/4425 Telegraph from Mary to Michael Davitt, 1895

During Davitt’s journey to Australia, disaster struck his family in Ireland, when his six-year-old daughter Kathleen died suddenly from the flu. However, Davitt’s wife pressed him to continue his ‘mission’, in a telegram he received from Mary in Colombo, Sri Lanka. Following his wife’s advice, Davitt continued on his voyage to Australia. 

Following his tour of Australia and New Zealand, Davitt published Life and Progress in Australasia in 1897. His book focuses on the gold rush in Western Australia and particularly on the town of Coolgardie.

MS 9649/348 Crowd of men at a sale of mining lots in Coolgardie, 1895

 

Davitt describes Coolgardie as ‘full of the gold-seeking fever’, with miners from vastly different backgrounds. In his diary for Western Australia MS 9565 he lists these as ‘any number of men with University training, pressmen, politicians, barristers, lawyers…all here on same gold hunting purpose’. The independence of the miners from the Australian authorities is illustrated by his photographs of a fire on Bailey Street in Coolgardie, which he reports in his diary was caused by the burning of an effigy of the Mayor of the town. 

MS 9649/373 Group of Aboriginal Australians under a tree near Great Boulder, Kalgoorlie, Western Australia, 1895

 

 

Davitt includes an interview with Catholic bishop Matthew Gibney in his book. Gibney discusses the mistreatment of Aborigines, the privatisation of Aboriginal land and hunting grounds in Western Australia. In Life and Progress Davitt declares that ‘the white man’s law justifies him in stealing the black man’s country, his wife, and daughters whenever he wants them; but to take a sheep from this moral professor of the ten commandments is to earn the penalty of a bullet!’

Davitt, as a radical politician and writer from a famine emigrant, working class background, was an important figure to the Irish diaspora in Australia. Davitt’s family were part of the million people who emigrated from Ireland to England, the United States and Australia to escape starvation after the failure of the potato crop during the Irish Great Famine. His importance to the Irish diaspora is evident throughout the Davitt photographic collection as large welcoming committees were organised to from MS 9649/32 below, where Davitt is welcomed at the train station in Maryborough, Victoria, Australia.
