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.

Horse-riding therapy improves self-confidence in children

Horse-riding therapy helps to improve self-confidence in children, and changes their perception of themselves. It puts them in a totally new environment where they can be free of any judgement.

According to Wijbren Nell, who achieved his Honours degree in Psychology at the University of the Free State (UFS), this is the ideal therapy when working with children with disabilities. He said it was amazing to see how they developed.

He was part of a group of Honours students in Psychology who received the best postgraduate Service Learning award in the Faculty of the Humanities for their community project. In 2015, this project by Wijbren, Hershel Meyerowitz, Gerán Lordan, Melissa Taljaard, Simoné le Roux, and Adriana de Vries, was part of their module Community and Social Psychology. They were honoured at the Faculty’s prize-giving function on 15 April 2016.

Purpose of project

“Our purpose with the project was to demonstrate to the children that they could still accomplish something, despite their disabilities,” Wijbren said. The students work on a weekly basis with learners from the foundation phase of the Lettie Fouché School in Bloemfontein. Marie Olivier’s Equistria Therapeutic Development Trust serves as the site for the community project. She has a long standing partnership with the UFS.

Horse-riding and therapy

According to Wijbren, the idea was to stimulate the psychomotor functioning of the children, as well as to promote their psychological well-being. He said research has shown that there is incredible therapeutic value in horse-riding. In this specific case, it has improved the children’s self-confidence, as they may have a poor self-image as a result of their disabilities.

“At the beginning of the year, there was a girl who didn’t even want to come close to a horse, let alone getting onto the horse. We kept on trying, and, once she was on the horse, we couldn’t get her down. This was the amazing thing about the project,” said Wijbren.

Award a surprise

Wijbren said the award was a honour and surprise to his group. He was full of praise for Dr Pravani Naidoo, a lecturer in Psychology at the UFS, who coordinates the therapeutic horse riding project. “She has a tremendous passion for this project, and challenged us to think on our feet. She is a real inspiration.”
