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.

New violinist for Odeion String Quartet

2013-02-06

Samson Diamond
06 February 2013

The Odeion String Quartet has a new member, a young accomplished violinist with a string of awards to his name. Samson Diamond, who won the Standard Bank Young Artist Award for Music in 2010, has joined the quartet. He is the first male member the quartet has had for about five years. The Soweto-born violinist replaced Denise Sutton, former leader and first violinist. He will lead the quartet, a flagship of the university and the only resident string quartet at a South African university. The other three members are Sharon de Kock (violin), Jeanne-Louise Moolman (viola) and Anmari van der Westhuizen (cello).

Twenty-eight year old Diamond, a graduate of the Royal Northern College of Music in Manchester, UK, says he is looking forward to working with students from the Odeion School of Music. “I am sure there are many talented students here.”

The musician, who obtained both his Bachelor of Music Honours degree and his Masters of Music Performance degree with distinction, will be based in Bloemfontein on a full time basis. As a member of the quartet, he will be giving concerts, coaching chamber music for the various chamber ensembles and will also give individual lessons to some of the violin students at the School.

Diamond, who started playing the violin at age ten, boast a long list of achievements. At age 12, he was leader of the Buskaid Soweto String Ensemble, one of the country's prominent youth projects. He was a founding member of the jazz classical band Quattro Fusion and former leader of the Diamond quartet. He has performed before many distinguished guests, including Queen Elizabeth II, the Duke of Edinburgh and former presidents Nelson Mandela and Thabo Mbeki.

Diamond says being the first male member in years will not bring about a change in the quartet He says it is about the standard of playing and the calibre of music.

“Music is music whether you work with men or women.”

Diamond’s first performance as member of the quartet will be on 21 February 2013. Details about the performance will be communicated later.
