In the video, there are two men wearing white lab coats and blue gloves. The man on the left is writing on a whiteboard with a marker. The whiteboard has various mathematical equations and formulas written on it. The man on the right is standing next to him, watching him write. The man on the left finishes writing and turns to the man on the right, who is now speaking to him. The man on the left looks confused and starts to ask questions. The man on the right is smiling and seems to be explaining something to him. The background is dark, and there are no other visible objects or people in the video.
