In the video, a woman is standing in front of a whiteboard. She is wearing a black and white striped shirt and has her hair in a braid. The whiteboard has the word "ENTROPY" written on it, followed by the definition "Measure of inform of uncertainty." The woman is speaking and gesturing towards the whiteboard as she explains the concept of entropy. She then draws a graph on the whiteboard, which shows the relationship between entropy and uncertainty. The graph has a blue line that goes up and down, representing the fluctuation of entropy over time. The woman continues to speak and gesture as she explains the graph.
