Global Citizen Invitation Prof Thuli Madonsela 4 July 2024

The University of the Free State (UFS) and the South African Chamber of Commerce United Kingdom (SACC UK) are pleased to present a Global Citizen Series conversation, South Africa’s Future in Focus: the post-election impact on social justice, service delivery, higher education, and the economy, from the perspective of Prof Thuli Madonsela, Director of the Centre for Social Justice in the Faculty of Law at Stellenbosch University and Professor of Law in the Law Trust Research Chair in Social Justice Studies.

As part of the Global Citizen Webinar Series, Prof Madonsela – a member of the International Anticorruption Advisory Council and Global Justice Leaders – will join UFS Vice-Chancellor and Principal, Prof Francis Petersen, and SACC UK Chairperson, Sharon Constançon, for a conversation that explores what the future holds for social justice, service delivery, higher education, and the economy in South Africa.

After thirty years of democracy, South Africans once again made their mark on 29 May 2024 in one of the most pivotal elections since 1994. Join us in person during the Free State Arts Festival or online as we explore South Africa’s Future in Focus: The post-election impact on social justice, service delivery, higher education, and the economy.

Date: Thursday 4 July 2024
In-person event SA time: 18:00-20:00 SAST, Centenary Complex, UFS Bloemfontein Campus
Webinar SA time: 18:30-19:30 / UK time: 17:30-18:30

About Prof Thuli Madontsela

Prof Thuli (Thulisile) Madonsela is the Director of the Centre for Social Justice (CSJ) in the Faculty of Law at Stellenbosch University and Professor of Law in the Law Trust Research Chair in Social Justice Studies. She is the founder of the Thuma Foundation for Democracy Leadership and Literacy and a member of the African Academy of Sciences. She was recently appointed to the UN Scientific Advisory Board and as Chairperson of Cities Alliance. She is a member of the International Anticorruption Advisory Council and Global Justice Leaders.

The former Public Protector of South Africa and full-time Commissioner in the South African Law Reform Commission was one of the 11 technical experts who helped draft the South African Constitution, and is a co-architect of several constitutionally mandated laws, including the Equality Act, Employment Equity Act, and the Promotion of Administrative Justice Act. She has an extensive background in applied constitutional, social justice, and administrative law principles, mainly based on her years of public service and her investigation of improper conduct in state affairs as Public Protector. A regular sought-after keynote speaker, Prof Madonsela has written, taught, presented papers, and published on these matters and ethical leadership, good governance, and gender mainstreaming for decades.

Prof Madonsela helped draft several international human rights instruments at UN, AU, and SADC levels, as well as country reports on such matters. She currently teaches Constitutional Law, Social Justice Law, Administrative Law, and Constitutional Governance and Ethical Leadership. She holds eight honorary law doctorates, in addition to two law degrees, a Harvard Advanced Leadership Certificate, and other postgraduate qualifications.

Named one of Time’s 100 most influential people in the world in 2014, Prof Madonsela’s global recognition includes more than 70 awards, including Rotary’s Paul Harris award, the Commonwealth Lawyers Truth and Justice award, and the global ACFE’s Cressy award. Prof Madonsela is a mother of two, a philanthropist, and an avid mountaineer who has summited Mt Kilimanjaro twice under the #Trek4Mandela-#Caring4Girls anti-period poverty campaign and the Musa Plan for Social Justice, and regularly hikes for the #Action4Inclusion campaign, a quest to end student debt.

UFS physicists publish in prestigious Nature journal

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
