For those who are not from South Africa, "car guarding" is a widely practiced profession. Car guards are the self-proclaimed super heroes of the street, claiming to watch your car whilst you are away, or even help you park it. You are expected to tip, and heaven help you if you don't.
We decided to take to the streets of San Diego and see how people reacted to experiencing car guards for the very first time.
Matrices can be thought of as transforming space, and understanding how this work is crucial for understanding many other ideas that follow in linear algebra.

The enigmatic equation e^{pi i} = -1 is usually explained using Taylor's formula during a calculus class. This video offers a different perspective, which involves thinking about numbers as actions, and about e^x as something which turns one action into another.

After controversy surrounding terrorist group ISIS chopping off statues' heads as well as statues being defaced in South Africa, the statues of the world get together for their annual meeting.
Tempers flare, fingers are pointed & tensions rise...but is there still hope for these once-noble icons in a modern world?

Derick Watts & The Sunday Blues return with their most ridiculous song yet! This time the boys chronicle the journey of two ordinary young men who splurge out & live large on payday, their spending sprees making those of celebrities like P. Diddy and Nicki Minaj look dull in comparison!
Alas though, reality comes back to bite them and they have to figure out how to get by for the rest of the month until payday comes around again. Will the boys learn their lesson this time around?
Featuring guest appearances by Jack Parow, Jeannie D, former-Miss South Africa Cindy Nell & The Kiffness, it's the song everyone can relate to - PAYDAY!
