From an early age, many have been taught that strangers are not only a danger to the individual, but to the communities too.

A StrangerKind (ASK), an organisation hosting unconventional conversations in communities on topics and responding to questions that many may not have the opportunity to ask, has partnered with the University of the Free State to host the talks that aims to promote curiosity, diversity, and social cohesion.

As part of the ASKcampus – a first to be hosted at any university in the country – participants will have an opportunity to talk to a stranger in a safe setting and ask any question that comes to mind, without any judgement.

Michelle Nöthling, Assistant Researcher in Kovsie Support Services, said: “The ASK event is an opportunity for participants to pick a topic from a list that sparks curiosity and book an available 45-minute time slot. During your session, you sit down to a one-on-one conversation with a stranger who will briefly introduce themselves and their topic. They will then share their personal life experience on that topic with you.”

The event, which will be launched at the Thakaneng Bridge, Bloemfontein Campus, on 28 July 2022, is open to both UFS staff and students.

“During the individual sessions, participants may ask the strangers anything about the chosen topic. We even encourage you to ask those questions that you might otherwise have been too shy, or felt were too ignorant, to ask. What is more, is that the strangers you will meet will be fellow UFS staff and students. But you will not know who your stranger is until you sit down with them,” said Michelle.

Individuals who want to know more about becoming a UFS stranger are encouraged to visit the organisation’s YouTube channel or register to attend training and become a ‘stranger’.

Be curious. Be brave. Talk to strangers.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
