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 congratulates Free State on matric results

The University of the Free State (UFS) congratulates the Free State and its learners on their outstanding performance in the 2016 matric results. The university, who also plays a role in promoting excellence at school level, is proud of the Free State’s achievement as the best-performing province in the country with a 93,2% pass rate, excluding progressed learners.

“On behalf of the university community I would like to congratulate the Free State MEC of Education, Tate Makgoe, who is also a member of the UFS Council, and the Department of Education in the province on this fine achievement. The UFS is proud to be involved in projects that contribute to the success of the province’s learners. These include the Internet Broadcast Project (IBP) and the Schools Partnership Projects (SPP). The projects help to improve the quality of teaching and help learners to overcome severe domestic conditions in rural areas,” says Prof Nicky Morgan, Acting Vice-Chancellor and Rector of the UFS.

Internet Broadcast Project

The UFS IDEAS Lab in the Department of Open and Distance Learning on the UFS South Campus supports learners in 83 schools through the IBP with the help of academic videos. The project is a collaboration between the university and the Department of Education in the province. It includes support for subjects such as Mathematics, Physical Science, Life Science, Economics, Accounting, and Geography.

A purpose-built school appliance, comprising a projector, speakers, and a PC, is set up at each school, where learners receive video lectures from highly-qualified teachers.

During a function held in Bloemfontein on 5 January 2017 to congratulate performing schools in the province, Mr Makgoe made special mention of the IBP and said that part of the success of the province can be attributed to the project. Many of the top performing schools had learners who participated in the project. One of the districts that forms part of the project, the Xhariep District, was announced as the top performing district in the province, and is second in the country.

Schools Partnership Projects

The SPP focuses on teachers in order to have a more sustainable impact, with 69 schools in the Free State and Eastern Cape being part of it.

It makes use of mentors (30) who assist teachers and headmasters with school management, Mathematics, Physical Science, Accounting, and English as language of learning. The project has an annual budget of more than R15 million – all the funds come from sponsors outside the UFS.

Mentors visit schools and share knowledge, extra material, and technology to improve the standard of teaching. The change has been significant. Matric results and Bachelors pass rates have improved dramatically in these schools.

Another aspect is the identification of learners with potential (so-called first-generation students) to go to university. They are assisted through extra classes and in applying for tertiary education and bursaries.

Many of them currently study at the UFS, and also receive mentorship at university.

Dr Peet Venter, SPP Project Manager, said his team is proud to be part of the process of helping the Free State to become the number one province in the country again.

Both the IBP and SPP was started in 2011 and are managed from the university’s South Campus in Bloemfontein.
