In the video, a man is standing in front of a whiteboard and writing on it with a marker. He is wearing a green shirt and a red and blue sweater vest. The whiteboard has some writing on it, but it is not clear what it says. The man is smiling and appears to be enjoying himself as he writes. Behind him, there is a poster of Albert Einstein on the wall. The man continues to write on the whiteboard and then turns to the camera, still smiling.
