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.

Alexander Ramm Cello Recital with Pieter Jacobs (piano)

2016-04-15

Description: Ramm Tags: Ramm

Alexander Ramm

“Ramm plays with enormous musical authority. Unlike many young instrumentalists, he is not intimidated by the reflective or the elegiac; nor is he nervous about the length of pauses, or the creation of inter-phrase silence. He has a phenomenal technique and he demonstrated it to full effect in this captivating performance.” (Cape Times)

Alexander Ramm belongs to the new generation of cellists recognised for his appealing artistic creativity and unprecedented technical skills. Alexander started his musical education at the age of seven at the Glier music school (Kaliningrad) with Svetlana Ivanova. Her extremely serious attitude to music studies and pedagogical talent revealed the rare musical capabilities of this young cellist.

After moving to Moscow at the age of ten, he was accepted to the class of Maria Zhuravleva at the Chopin Moscow College of Music Performance. From 2007, he continued his professional education at the Moscow Conservatory in the class of the renowned musician and the People’s Artist of the USSR, Natalia Shakhovskaya, an outstanding performer and pedagogue who taught most prominent Russian cellists. Since 2012, he has become a postgraduate student at the Hanns-Eisler Hochschule fur Musik under the guidance of the famous cellist, Frans Helmerson.

From the age of nine, when he made his debut as a soloist with the Kaliningrad Chamber Orchestra, Alexander brilliantly performs with solo programmes and as a soloist with leading orchestras in Russia and worldwide.

He is prizewinner at several international competitions:
1st prize: 4th Moscow Competition for young cellists (2003)
1st prize: 1st Cambridge International Boston Competition (Massachusetts, 2005)
Grand-Prix: Moscow Festival of Romantic Music (Moscow, 2006)
4th prize: 5th UNISA International String Competition (South Africa, 2010)
1st prize: 3rd Beijing International Music Competition (Beijing 2010)
1st prize: 1st All-Russia Music Competition (Russia, 2010)
Prizewinner: Janigro Cello Competition (Croatia, 2012)
Prizewinners: Swedish Duo Competition with duo partner Anna Odintsova (2012)
3rd prize: Paulo Cello Competition (2013) – becoming the first Russian prizewinner in the history of this prestigious contest
2nd prize: XV International Tchaikovsky Competition (2015)

Alexander participated in masterclass festivals at Courchevel Academy and Holland Music Sessions, where he took lessons from the famous musicians such as F. Muller, R. Latzko, M. Kliegel and U. Wiesel. In 2011, he took part in the well-known Verbier festival, where he studied with H. Hoffmann, F. Helmerson, M. Suzuki, L. Power and F. Radosh. At the end of the festival, he was awarded the Neva Foundation top-level prize for gifted students.

Alexander cooperates with such outstanding conductors as V. Gergiev, V. Spivakov, A. Levin, K. Orbelyan, V. Polyansky, S. Kochanovsky, M. Fedotov, A. Slutsky, A. Sladkovsky.

He will be accompanied by Pieter Jacobs, a graduate of the University of Pretoria, who then furthered his studies at Yale in the United States, where he pursued his performing career with considerable success as a soloist and chamber musician in Boston, Cambridge and New Haven before returning to South Africa to perform and teach at the University of Pretoria. Pieter is regarded as one of SA’s foremost pianists and chamber musicians.
