In his book, The World is Flat, Thomas Friedman mentions how at first countries, then companies, and eventually communities went global. In true flat-world fashion, a combined team of the University of the Free State (UFS) and the Astronomical Society of South Africa – led by Prof Matie Hoffman, Associate Professor in the Department of Physics – participated in a once-in-a-lifetime event with their counterparts from the Ellinogermaniki Agogi School and the Skinakas Observatory in Greece.

On 21 December 2020, Earth was treated to the Jupiter-Saturn conjunction, when the two planets were only 0.1 degrees apart in the sky. Although conjunctions are regular phenomena, NASA mentions that the great conjunction of Jupiter and Saturn in 2020 was the closest since 1623 and the closest observable since 1226! A pinkie finger at arm’s length could cover both planets – although they were still millions of kilometres apart in space.

Planning started months ahead of the event, with the Ellinogermaniki Agogi Observatory in Greece and the Boyden Observatory in Bloemfontein chosen as the two selected vantage points. From both the Southern and Northern Hemisphere, the conjunction would be broadcast live on YouTube. As with any other technical project on an international scale, challenges arose. For example, in the Northern Hemisphere, it was already dark at 17:45 while the South African astronomers were still basking in sunlight until after 19:00. The conjunction would only be visible from South Africa after 19:30, almost two hours after it would be visible in Athens. The time was well used, with the event including a word of welcome by the Consul General of Greece in South Africa, Ioannis Chatzantonakis, presentations on Saturn and Jupiter, as well as a virtual tour of the Boyden Observatory, emphasising its connection with Greece through its first Director, Stefanos Paraskevopoulos. 

On Saturday, 19 December, the teams ‘gathered’ on opposite sides of planet Earth to do a dry run. One could sense the urgency and tension as both teams realised that they would have a huge captive audience on YouTube, and plans had to be made in case of connectivity challenges and if the weather did not allow the conjunction. As preparations progressed, Prof Hoffman was talking to his Greek counterparts and was simultaneously walking around with his laptop to share the landscape and activities via his webcam with colleagues in Greece. 

Monday 21 December 2020 – the weather prediction was correct. Clouds covered the Free State sky and scattered raindrops started to fall. Revert to Plan B. A recording made on Saturday evening was shared via the YouTube link, while a live feed of the conjunction from elsewhere in South Africa was arranged. From both sides of the world, information was shared about the history of the venues, as well as the marvel of what was happening in space. Fortunately, expert planetary photographer Clyde Foster was able to share a live feed just after 19:30 from the observatory at his home in Centurion, Gauteng. Those attending the event where visuals and speakers were together on one screen – yet thousands of kilometres apart – watching an event in outer space, will indeed agree with Thomas Friedman: the world is flat. The live-stream event of the conjunction was a catalyst that will result in continued collaboration between the UFS and colleagues in Greece in the field of astronomy. 

By the time of this writing, the livestream has reached more than 50 000 people.

UFS presents sport concussion programme for schools
2008-11-14

The Sports Medicine Clinic at the University of the Free State (UFS) will present a sports concussion programme for schools in the Free State.

“The Pharos Schools Concussion Programme makes the latest methods and technology in concussion management available to learners who play contact sport,” says Dr Louis Holtzhausen, Programme Director of Sports Medicine at the UFS.

The great risk of concussion is that there is an uncertainty about when a player can return to a sport with safety and with the minimum complications in the brain. This programme fills that gap to a large extent.

“By using this programme, no player who suffers concussion will return to play before it is medically safe to do so. The programme also educates players, parents, coaches and the medical fraternity on how to manage sports concussion,” says Dr Holtzhausen.

The programme has been designed for hockey, soccer, cricket, rugby and other contact and collision sports.

SA Rugby has used the programme for professional players for the last five years and advocates that all school rugby players should participate in the programme.

Several sports teams from schools in and around Bloemfontein as well as the University’s Shimla and Irawa rugby teams have already been tested. This will provide invaluable information in the management of possible head injuries.

“We can now give definite guidelines to players and coaches regarding the safe return of players to teams after such an injury. It takes a lot of the guesswork out of the management of concussion and provides peace of mind to coaches, parents and players regarding serious injuries,” says Dr Holtzhausen.

By enrolling in the concussion programme, learners and their parents are ensured of among others:

A baseline computer brain-function test before the start of the season.
Information on how to recognise and treat concussion, including a fieldside information card for the player’s team.
A free consultation and neurological examination by a sports physician after any suspected concussion.
As many brain-function tests and sports-physician consultations as necessary after any concussion, until complete recovery.
Referral to a network of specialists if necessary.

The Pharos Programme uses a cognitive function evaluation called Cogsport. This is a neurophysiological test that measures brain function before the season starts. In this way, a baseline standard is established and, should concussion occur during the season, the extent of it can be measured according to the baseline and rehabilitation.

“Once we have the baseline values, the concussed player’s return to those levels must be monitored. He/she can return to light exercise in the meantime and semi- and full-contact can be introduced at appropriate times,” says Dr Holtzhausen.

The cost of enrolment is R200 per learner, regardless of the number of concussions suffered or sports physician consultations received. “By enrolling in this programme, parents will ensure that their child has the best chance of avoiding the potentially serious consequences of concussion, including learning disabilities, recurrent concussions, epileptic fits and even death,” says Dr Holtzhausen.

More information on the programme can be obtained from Ms Arina Otto at 051 401 2530.
