New projection system contributes to enhanced experience at Naval Hill Planetarium

During the installation of the new computer and projector equipment at the Naval Hill Planetarium, were from the left: Dieter Schwab and Alex Reither from Sky-Skan, and Prof Matie Hoffman, Barry Crous (Instrumentation), and Pat van Heerden (Department of Physics) from the UFS.

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.

Eusibius McKaiser gives first talk on new book at Kovsies

Students and staff from our university got the first glimpse of political and social commentator Eusibius McKaiser’s new book, There is a Bantu in my bathroom, during a public lecture of the same title held by the author on the Bloemfontein Campus.

McKaiser told the audience that they were amongst the first people to get a preview of his book, a collection of essays on race, sexuality and politics.

His talk centred on domestic race relationships, posing the question whether it was acceptable to have racial preferences with regard to whom you live with. Recounting an incident he encountered while looking for a flat in Sandton, McKaiser said the country was still many kilometres away from the end-goal of non-racialism.

McKaiser, who hosted a weekly politics and morality show on Talk Radio 702, and is a weekly contributor to The New York Times, said the litmus test for non-racialism in South Africa was not what people utter in a public space, but rather what was said in private.

“We need to talk more about the domestic space. In public, we are very insincere and quick to preach non-racialism.”

Recounting conversations he had with Talk Radio 702 listeners on the incident, McKaiser said that preference about whom you live with was not specific to white people’s attitude. He said many of his black listeners also felt uncomfortable living with a white person. “The question is, ‘What do these preferences say about you? What does it say about where we are as a country and people’s commitment to non-racialism?’”

McKaiser was the guest of the International Institute for Studies in Race, Reconciliation and Social Justice.
