The Naval Hill Planetarium at the Centre for Earth and Space on Naval Hill was inaugurated on 1 November 2013. It was the first digital planetarium in Africa south of the Sahara. 

The Department of Physics at the University of the Free State (UFS) is responsible for the Naval Hill Planetarium (formerly the Lamont-Hussey Observatory). The department uses the planetarium to educate and inform citizens about the natural sciences. The planetarium, together with the Boyden Observatory, is also important for the display and communication of South Africa’s astronomical heritage.

The planetarium system was recently upgraded in a project that cost R6 million. According to Prof Matie Hoffman from the Department of Physics, it was time to upgrade the computers and graphic cards, and to replace the lamp projectors with laser projectors.

Funding for the state-of-the-art equipment came from the Faculty of Natural and Agricultural Sciences and the Information and Communication Technology Services (ICT Services) at the university. Businesses in Bloemfontein – First Technology and Raubex Construction – also contributed to the project. 

Presenting programmes more often

Planetarium specialists Dieter Schwab and Alex Reither from Sky-Skan Europe, based in Germany, installed the new equipment over a period of two weeks.

Prof Hoffman says the new equipment will enhance the experience of people visiting the planetarium for a close encounter with the wonders of the universe to deepen their appreciation of science and astronomy.

“Besides a clearer image with better colour, the new projectors will also be more economical to operate. This means we will be able to offer programmes at the planetarium more often,” he says. 

The upgrades also include new software. Prof Hoffman explains that the software will enable more sophisticated presentations and open the door to the use of the planetarium for higher level visualisation of scientific data where any large data sets with many variables are involved, such as climate science, astrophysics, and cosmology. 

Offering an incredible experience

After completion of the installation, a period of two weeks will be spent on training to master the use of the new equipment and the software. The public can expect the first show with the new equipment at the end of June. 

“I am most looking forward to the planetarium creating an incredible experience – better than in the past – for the public and increasing everyone's admiration and understanding of the universe. I also believe the planetarium is an excellent facility to improve students' skills in science communication, and it provides these students the opportunity to share their knowledge with the public,” concludes Prof Hoffman.

Sometimes it is difficult for language departments to be topical and to show their relevance for the people out there. However, with the RSG Crossword Tournament, this became possible and Afrikaans could be celebrated in a positive manner. This is what Prof Angelique van Niekerk, Head of the Department of Afrikaans and Dutch, German and French at the University of the Free State (UFS), had to say about this initiative.

Interest during the Vrystaat Arts Festival exceeded all expectations. Altogether, 46 participants from across the country participated on 15 and 16 July 2016. Ilse van Hemert from Pretoria was crowned as the first South African crossword champion.

New dimension to language milieu

Prof Van Niekerk said people are familiar with crossword puzzles from the media, and it was the first time that a tournament like this was presented to the public in South Africa. “This tournament brings something like linguistics and linguistic sensitivity to the fore,” she said. “It is another dimension of the language milieu.” This is exactly why her department would like to see it grow in future.

Wordplay serves as inspiration

The idea for the tournament is based loosely on the film, Wordplay (2006), which is set in New York, and the annual New York Times Crossword Tournament. The South African Tournament was presented in conjunction with the crossword group, XWord, Prof Van Niekerk’s department, and the radio station RSG as brand sponsor.

Crossword puzzles and blockbusters crosswords completed

“This tournament brings something like
linguistics and linguistic sensitivity to
the fore.”


Albe Grobbelaar from XWord said the winners were determined on a points basis. “Competitors had to complete two crossword puzzles and one blockbuster crossword. The difference between the two is that a blockbuster’s clues are within the blocks or grid, but with the crossword, you have white and black blocks with the clues separate on the outside.”
