School of Cosmic Physics Statutory Public Lecture 2013 – Wednesday 4th December
“Solving the Puzzle of Dark Matter?” by Professor Lars Bergström, Professor of Theoretical Physics, Stockholm University and Secretary of the Nobel Committee for Physics.
Wednesday 4th December at 6:00pm. Moore Auditorium, O’Brien Centre for Science (Science Centre East), UCD, Dublin 4. Admission is free.
Location: Building No. 67 on http://www.ucd.ie/maps/2013/UCD_Map_August_2013.pdf
The Moore Auditorium is located on the ground floor (right-hand side) of the new UCD O’Brien Centre for Science (Science Centre East).
Abstract:
Cosmologists are becoming ever more certain that a large fraction of the mass in the universe is invisible and does not emit or absorb light. This talk will give a basic introduction to the history and status of the dark matter problem, and discuss three different methods to find out what it is. First, the LHC accelerator will have a real chance of discovering dark matter particles, if the mass scale is not too high. Second, direct search for scattering of dark matter particles in underground detectors is reaching a sensitivity where a signal may soon be found. The third method, which is useful even if the dark matter particle would have a very high mass, uses indirect detection through annihilation of dark matter particles in our galaxy to gamma-rays, neutrinos or antimatter. All three methods have now reached a sensitivity that a dark matter signal may be soon be found. However, this also means that one has to be aware of false claims of discovery. A summary of the current, somewhat confusing, experimental situation will be presented.

...obituaries of prominent individuals The manuscript has been preserved in the @Library_RIA since 1883. (3/3) @HistFest #DIASdiscovers #connacht #books
The Annals of Connacht is a vellum manuscript that was written in the mid-16th century. The contents were derived from older annals compiled for the O’Conors of the Connacht and contain an annual record of significant events over 320 years, and... (2/3)
Date: 19 October 1944 Paper: The Irish Press Synopsis: DIAS has been publishing books since it's founding. One such early publication is the edited manuscript of the Annals of Connacht (Annála Connacht) which was edited for the first time by Martin Freeman of DIAS. (1/3)
This work was to help towards the preservation of the Irish Language, to maintain it's continuity with the past, and was to become a resource for teachers to check pronunciation #DIASdiscovers #Irish #Irishlanguage #CelticStudies #Gaelic
The researchers used the International Phonetic Alphabet, slightly modified to represent vowels and consonants of living speech. At that time there were concerns over the deterioration of the Irish language due to the "overpowering influence of English"
Date: 02 June 1943 Paper: The Irish Press Synopsis: In 1943, a phonetic investigation led by Brian Ó Cuív, Risteárd B. Breathnach and Tomás de Bhaldraithe of DIAS would begin the first systematic scientific recording of the varied sounds of modern Gaelic speech.

The papers were 1) Affine Field Theory: conservation identitites and relation to Weyl and Eddington 2)The Union of the three fundamental fields (Gravitation, Menson, Electromagnetism) Which went on to secure worldwide acclaim. #DIASdiscovers
Date: 01 December 1943 Paper: The Irish Press Headline: Two Papers by Dr. Schroedinger Synopsis: 1943 was a busy year for Schroedinger. Not only did he deliver the "What is Life?" Lectures in @tcddublin in February in November he delivered two papers in the @RIAdawson (1/2)

"In the lives of St. Patrick, the two saints are invariably fused into one", said Prof. O'Rahilly in his lecture. The lecture was a condensation from O’Rahilly’s book “The two Patricks: a lecture on the history of Christianity in fifth-century Ireland”. (4/5)
He was known by his first name Patricius, which in later times would lead to confusion as he was succeeded by another apostle of the same name (Saint Patrick or Patricius in Latin). (3/5)
He spoke on "Palladius and Patrick". Palladius was the first bishop of the Christians of Ireland. (2/5)
Date: 21st March 1942 Paper: The Irish Press Headline: Palladius and Patrick | School Of Celtic Studies Lecture Synopsis: The first public lecture under the auspices of the School of Celtic Studies was delivered in Trinity College by Professor T. F. O'Rahilly in 1942. (1/5)
As part of our ongoing participation in the @HistFest we decided to take a look into the Irish Newspaper Archives and see where DIAS made it into print over the last 80 years. There were so many articles, the hardest part was selecting what we would post. We hope you enjoy!
@AReillyFailte @CultureNight @VisitDublin Thanks Antoinette! Glad you enjoyed 😊
