Hello, my name is Mark Sundaram! I'm a university prof with a PhD in Medieval Studies. I use language, literature, and history to explore the web of connections in the world around us. Many of my videos start with a word as a jumping off point, with its history and etymology opening up a way to explore history and culture more widely. Others examine literary devices, cognitive science, myth, history of science, and other topics. The endless knot is a common visual motif of an interconnected knot with no beginning or end, found in many cultures around the world. My use of the symbol is a reference to the 14th c. poem "Sir Gawain & the Green Knight", where it describes the pentangle which Gawain has emblazoned on his shield as a symbol of the interconnectedness of things. Here it also gains significance from its comparison to the cognitive science hexagram which shows the interrelated nature of various fields in cognitive science.
