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.

Eusebius McKaiser talks about the magic of books

If you want to turn around this country in terms of the rot in education, you have to start reading. You have to read for your degree."

This was the message from writer and political analyst, Eusebius McKaiser, at a public lecture hosted by the UFS Library and Information Services to celebrate South African Library Week.

Addressing the audience that consisted mostly of students, McKaiser, author of “A Bantu in my bathroom,” said it is not too late to start reading.

"We claim we are too busy as adults, but what is the opportunity cost of not reading? I think we lose our humanity, our sense of awe in the world around us when we stop reading as adults. Instead of saying we are too busy, we will do well to ask ourselves what is the cost of no longer reading as much as we did when we were children."

Reading from some of his favourite books, McKaiser spoke about writing techniques and the magic of books. He read excerpts from JM Coetzee's book “Disgrace,” which he considers to be the most important South African novel. He also read paragraphs from books by Rian Malan, James Baldwin and K Sello Duiker – calling the latter a genius.

Reflecting on the role of fiction, McKaiser said the genre is misunderstood and not utilised sufficiently by academics. "We see fiction as something restricted to the English Department or literary departments. I think fiction can be used as a tool in many departments in the humanities. It gives more real material for exploring complicated questions in the humanities and thought experiments that resemble life."

McKaiser also discussed the role of librarians and writers, saying writers should write what they like, but should not ignore the context. "As academics, librarians, teachers, we have to write for the context in which we teach. We have to order books for the context in which we are librarians and as academics we must not write textbooks for students who live in New York. We have to write textbooks for students who come from townships.”
