SCP Statutory Public Lecture: February 10, 2020 – Professor Heino Falcke
Speaker : Professor Heino Falcke, Radboud University Nijmegen, The Netherlands
Title : The First Image of a Black Hole
Abstract: One of the most bizarre, but perhaps also most fundamental predictions of Einstein’s theory of general relativity are black holes. They are extreme concentrations of matter with a gravitational attraction so strong, that not even light can escape. The inside of black holes is shielded from observations by an event horizon, a virtual one-way membrane through which matter, light and information can enter but never leave. This loss of information, however, contradicts some basic tenets of quantum physics. Does such an event horizon really exist? What are its effects on the ambient light and surrounding matter? How does a black hole really look? Can one see it? Recently we have made the first image of a black hole and detected its dark shadow in the radio galaxy M87 with the global Event Horizon Telescope experiment. Detailed supercomputer simulations faithfully reproduce these observations. Simulations and observations together provide strong support for the notion that we are literally looking into the abyss of the event horizon of a supermassive black hole. The talk will review the latest results of the Event Horizon Telescope, its scientific implications and future expansions of the array.
Short bio :
Heino Falcke is professor of astroparticle physics and radio astronomy at the Radboud University in Nijmegen, the Netherlands. He is chair of the science council of the Event Horizon Telescope, member of the royal Netherlands academy for arts and science, knight in the order of the Dutch lion, and recipient of the Spinoza price, the highest science award of the Netherlands.
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.

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)
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!
