A Virtual celebration of Africa Month

On 25 May 2020, Africa will celebrate the 57th anniversary of the founding of the Organisation of African Unity. A central tenet of the organisation, which was the predecessor of the African Union, is African solidarity. Member states undertook to coordinate and intensify their cooperation and efforts to achieve a better life for the people of Africa. The University of the Free State (UFS) has a long tradition of commemorating Africa Day and the ideas underpinning it. Every year, diverse events aimed at advancing African unity and solidarity take place during Africa Month – traditionally, the highlight is the Africa Day Memorial Lecture hosted by the University's Centre for Gender and Africa Studies

This year, celebrating African unity through significant events involving the physical presence of a large number of people, will likely be impossible. COVID-19 is ravaging the world and Africa may become one of the world regions worst affected by the consequences of the virus. Social distancing may be difficult to achieve in a continent with densely populated urban centres that often feature large informal settlements. Besides, the economies of African nations are not as robust as those of other world regions. The challenge that Africa is facing, appears to be one that can only be mastered by its people acting in solidarity and unity. The continent has already developed an Africa Joint Continental Strategy for COVID-19 Outbreak to combat the virus, and an Africa Taskforce for Coronavirus has been established. The ideas of African togetherness and the underpinning philosophy of Ubuntu may be critical for strengthening African solidarity at a time when it may be more relevant than ever.

The commemoration of Africa Day takes a different theme each year. This year, the UFS 2020 Africa Month celebrations will take a virtual format, with the theme of ‘Africa together forever’ underpinned by the COVID-19 global pandemic. The theme is particularly significant considering the context of the African continent; and only through the demonstration of solidarity and unity can Africa overcome the challenges of the global pandemic.

The University will host a variety of cultural and intellectual contributions on the dedicated UFS virtual Africa Month website. On Africa Day (25 May 2020), a virtual Africa Day function, which will be posted on the website, will conclude the Africa Month commemorations.

The diverse contributions to the 2020 virtual Africa Month activities will highlight the University’s commitment towards creating a diverse, challenging intellectual environment. The UFS strives as a research-led university, to provide an environment in which new ideas are incubated and debated; contributing towards its transformation process and African unity.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
