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.

Women have not internalised the fact that they can participate on an equal footing in politics with men. This is one of the conclusions made by Prof Lilian Lem Atanga in a study of the political participation of women in Cameroon.
“There still is a strong belief that women can’t deliver the goods (in areas such as politics),” Prof Atanga said. According to her, stereotypes were still entrenched in Africa and a lot had to be done to change societal perceptions of the role of women in politics.

Poor representation of women in politics
Prof Atanga, an associate professor at the University of Bamenda in Cameroon, was guest speaker at the First Humanities and Gendered Worlds Lecture 2017. The lecture was hosted by the Faculty of Humanities and the Centre for Africa Studies (CAS) at the University of the Free State (UFS) in the Equitas Auditorium, Bloemfontein Campus, on 3 August 2017. The title of the research fellow’s lecture at the CAS lecture was Gender, Discourse and Cognition and Implications on Political Participation.
She noted that although there had been a marked increase in the political participation of women in Cameroon, it still was insufficient. Of the 24 million people in the country, 52% were women but only 20% of the senators and 31% of parliamentarians were women.

Gender-segregated roles affect participation
And there are many reasons for this. “A lot more women still believe in gender-segregated roles and this affects their political participation.” Many men also don’t approve of women’s political participation.
In her study Prof Atanga found that stereotypes were also emphasised in the way the media in Cameroon reported on the roles of women.
