Stable atmospheric environments and near perfect weather conditions were the main reasons for the establishment of the Boyden Observatory a few kilometres outside Bloemfontein. This astronomical research observatory and science education centre is managed by the Department of Physics at the University of the Free State (UFS).

With the newly acquired astronomical spectrograph for the Boyden Observatory 1,5-m telescope, scientists will be able to gain visual access to both the Northern and Southern Hemisphere skies.

Collaboration with expert in stellar spectroscopy

The spectrograph, mainly developed and built by Dr Richard Gray, will be used collaboratively for astronomical research by the UFS and the Appalachian State University (ASU) in North Carolina, where Dr Gray is based.

Dr Gray is a world-renowned expert in stellar spectroscopy and leading author of one of the most influential textbooks on stellar spectroscopy, Stellar Spectral Classification, with co-author Christopher J Corbally.

Dr Gray recently received a Fulbright Scholarship from the Fulbright Foundation to spend a full year in the UFS Department of Physics, where he will lecture several Astronomy classes and do research in collaboration with personnel of the UFS Astrophysics Research Group. He will also lead the assembly of the instrument over the next few weeks, working with personnel and students in the Department of Physics as well as the UFS Instrumentation Division.

According to Prof Pieter Meintjes, Senior Professor from the UFS Department of Physics, some components of the instrument have been developed and constructed by the university’s Instrumentation Division, with key components purchased from funding by the Directorate: Research Development at the UFS.

Unique capability in infrastructure

“The availability of a sophisticated instrument of this nature on the 1,5-m telescope will place the UFS Astrophysics Group in an elite bracket in terms of the available infrastructure for astronomical research,” said Prof Meintjes.

He explained: “The combined polarimetric-spectroscopic capability in one single instrument is unique. Combined with the fact that it is hosted on a research instrument that is utilised and maintained exclusively by the UFS Astronomy Group in the Department of Physics, gives this group a competitive edge in relation to most international astronomy groups.”

The instrument is valued at close to R1,5 million.

According to Prof Meintjes, the instrument will be mounted at the backend of the UFS Boyden 1,5-m telescope and will allow them to do simultaneous polarimetry and spectroscopy of astronomical sources. “This is vital for the research we are working on,” he said.

International collaboration and student development

The instrument also brings with it the possibility of forging international collaborations for research as well as student development. “This can advance the stature of the UFS as an internationally respected research-led tertiary institution,” said Prof Meintjes.

The possibility of making the UFS Boyden 1,5-m telescope completely remote-controlled, is being investigated. “This will serve the observational needs of researchers from both the UFS and the ASU, with researchers at ASU able to access the telescope for their own in-house research programmes. The availability of such an instrument on the UFS 1,5-m telescope also opens up the possibility to accommodate visiting researchers from ASU or elsewhere in the world at Boyden,” said Prof Meintjes.

Sites of memory. Sites of trauma. Sites of healing.

2015-04-01

Judge Albie Sachs – human rights activist and co-creator of South Africa’s constitution – presented the first Vice Chancellor’s Lecture on Trauma, Memory, and Representations of the Past on 26 March 2015 on the Bloemfontein Campus.

His lecture, ‘Sites of memory, sites of conscience’, forms part of a series of lectures that will focus on how the creative arts represent trauma and memory – and how these representations may ultimately pave the way to healing historical wounds. This series is incorporated into the five-year research project, led by Prof Pumla Gobodo-Madikizela, and funded by the Mellon Foundation.

Sites of memory and conscience – and healing

“Deep in solitary confinement, I read in the Bible: ‘the lion lay down with the lamb … swords will be beaten into ploughshares.’” And with these opening words, Judge Sachs took the audience on a wistful journey to the places in our country that ache from the past but are reaching for a better future at the same time.

Some of the sites of memory and conscience Judge Sachs discussed included the Apartheid Museum, Liliesleaf, District Six Museum, and the Red Location Museum. But perhaps most powerful of them all is Robben Island.

Robben Island

“The strength of Robben Island,” Judge Sachs said, “comes from its isolation. Its quietness speaks”. Former prisoners of the island now accompany visitors on their tours of the site, retelling their personal experiences. It was found that, the quieter the ex-prisoners imparted their stories, “the gentler and softer their memories; the more powerful the impact,” Judge Sachs remarked. Instead of anger and denouncement, this reverence provides a space for visitors’ own emotions to emerge. This intense and powerful site has become a living memory elevated into a place of healing.

After Judge Sachs visited the National Women’s Memorial in Bloemfontein some years ago, he came to an acute realisation as he read the stories, experienced the grief, and saw the small relics that imprisoned commandoes from Ceylon and St Helena sculpted. “It’s so like us,” he thought, “our people on Robben Island making a saxophone out of seaweed, our people carving little things. It was so like us. It was another form of inhumanity to human beings in another period.”

The Constitutional Court

The Constitutional Court next to the Old Fort Prison is also a profound site of trauma and healing. Bricks from the awaiting trial lock-up were built into the court chambers. “We don’t suppress it, we don’t say let’s move on. We acknowledge the pain of the past. We live in it, but we are not trapped in it. We South Africans are capable of transcending, of getting beyond it,” Judge Sachs said.

Transforming swords into ploughshares

Judge Sachs had great praise for Prof Gobodo-Madikizela’s research project on Trauma, Memory, and Representations of the Past. “You convert and transform the very swords, the very instruments, the very metal in our country. In a sense, you almost transform the very people and thoughts and dreams and fears and terrors into the ploughshares; into positivity.”
