Smoothie Bike challenge
The Smoothie Bike Challenge feeds the body, soul and the mind in support of mental health awareness.

Smoothie lovers at the University of the Free State (UFS) pedalled furiously to create their favourite drink. The Smoothie Bike Challenge was recently introduced to the Bloemfontein Campus community by the Division for Organisational Development and Employee Wellness.

Blending bikes and berries

Kovsies staff members were invited to pop a handful of berries and bananas into a blender attached to a specially adapted bike that uses pedal power to turn the ingredients into a refreshing drink. 

Blending physical exercise and healthy eating is one way to ensure holistic health. The division wanted to raise awareness around mental health and the effects that fitness and healthy food have on the mind. 

Wheelie good fun

“The purpose of this initiative was to involve employees in a fun way to use their bodies to make a healthy drink. Individuals of all fitness levels could participate,” said Burneline Kaars, head of the organisational development and employee wellness division.

A precursor to Mental Health Awareness month

Participants provided the energy to make the smoothie and Employee Wellness provided the ingredients but the initiative also created awareness around mental health. This comes weeks before the country officially enters Mental Health Awareness month.

According to the government: “The month of October has been declared Mental Health Awareness month with the objective of not only educating the public about mental health but to reduce the stigma and discrimination that people with mental illness are often subjected to.”

An estimated 400 million people worldwide suffer from mental or neurological disorders or experience psychosocial problems. Initiatives such as the Smoothie Bike Challenge are some of the ways in which the UFS is attempting to ensure that staff members are taken care of and do not become statistics. In the light of these numbers, it is evident that continuous efforts are necessary to tackle the issue.

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.
