The Faculty of Economic and Management Sciences invites all its academic departments to participate in the 2021 celebration of Nelson Mandela Day by requesting their staff and students to become involved in a 67-minute fitness challenge to be held over a seven-day period, commencing on 18 July 2021. These kilometres can be completed by running, walking, swimming or on a bicycle (no vehicles permitted). 

These activities may be completed at any location, at any time from 18 to 25 July 2021 (terminating at midnight on 25 July). This ensures that social distancing protocols are adhered to, since each individual is completing the challenge on their own.

Participants will be required to provide relevant proof of the distance completed, as well as the date and time interval, by either submitting a picture of the treadmill screen, sharing the progress they logged by using a mobile app such as Strata, pictures of the number of steps completed, etc. (Send this via email to Reabetswe Parkies at Parkiesrg@ufs.ac.za upon completion – at the latest by 08:00 on 26 July 2021.)

Raising funds

To raise funds, each department in the faculty is requested to consider sponsoring a specific amount per kilometre completed by their staff and students. It is recommended that each department consider its available budget for this purpose and that the total departmental contribution should be capped at a specific amount to ensure that departments are not faced with open-ended liabilities.  We have sought and obtained approval from the Department of Finance for the use of UFS funds in this manner. To this end, for example, the School of Accountancy has pledged to contribute R10 per kilometre completed, capped at a maximum contribution of R6 700.

To encourage healthy competition and to increase the amount raised, departments will be encouraged to compete against each other and attempt to complete the most kilometres. Each department will donate their pledges to the charity of their choice.  In support of this noble cause, the Dean’s office has pledged a donation of R6 700 to the winning academic department, to be added to the department’s donation to the charity. 

We believe this is a very good marketing initiative, as well as an opportunity for the faculty to illustrate its commitment to social investment and community engagement.  It is also likely to contribute to improving the morale of the staff in the faculty. The UFS Community Engagement office has further indicated that it would like to arrange a radio interview to promote this event – to this end, we can raise awareness and place the spotlight on a worthy cause.

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.
