As students are returning to campus, Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison at Protection Services, believes it is important that they ‘know’ and practise safety at the UFS:

1) Know the number of your Department of Protection Services:

• Bloemfontein Campus: +27 51 401 2911(also in cases of GBV)
• Qwaqwa Campus: +27 58 718 5032 / 5029 / 5033
• South Campus: +27 51 505 1298

Protection Services staff are the experts on campus safety, and they are able to point out the safest routes on and around campus, especially after dark. They can also assist with any safety concerns you may have.

As a student, you are smart; use your senses:
o Never let a stranger in your room or apartment
o Never walk alone after dark.

2) Know how to use alcohol

Although drinking and driving is a big NO, there are some other cardinal facts about drinking that you need to take note of:

• Never consume a drink provided by a stranger
• Never leave a drink unattended
• Never drink too much too quickly
• Always leave a party with a buddy

3) Know the basics of personal finance

You will be bombarded with offers from credit card companies, clothing stores, etc. Know how to budget. If you do not know how to budget, please contact the Student Counselling and Development office to assist you. This skill will not only make your life easier at varsity, but also once you start earning an income.

Be aware of fraud. If something looks too good to be true, it often is.

Watch your wallet. Theft or robbery is a possibility.

4) Know how to be safe on the internet

You are spending a lot of time on the internet. Unfortunately, criminals are also spending time in cyberspace with the aim of taking advantage of unsuspecting people like you. This may include cyberstalking, which may lead to emotional or physical harm, or it may result in them taking your information or money through phishing scams. Do not become a victim and ensure that you
- never use the same password twice;
- never use unsecured Wi-Fi to access private accounts;
- always use passwords that are difficult to guess;
- never reveal important information such as your banking login details to strangers calling on the phone; and
- never mention your location online.

5) Know basic self-defence

Avoid being the victim of any form of harassment or assault. Learning basic self-defence techniques will help you to protect yourself from physical attacks.

Protection Services offer self-defence classes from time to time. Make use of the opportunity and equip yourself with these self-defence techniques. Also buy yourself pepper spray, which can give you time to escape.

“Lastly, be aware of your surroundings. Walk with a purpose, without headphones, and always pay attention,” says Van Jaarsveld.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
