This image depicts a lecture hall at Columbia University in the City of New York, United States. A large projector screen occupies the upper portion, displaying a Columbia University course webpage (columbia.edu/courses/221005). The webpage presents a syllabus or schedule for a computer science-related course, outlining topics such as Java programming, data structures, algorithms, recursion, and binary search, with associated dates (e.g., Sep. 3, Sep. 8 and 10), textbook chapters, and links to digital resources. The Windows operating system taskbar is visible at the top of the projected display. In the lower half of the frame, a male professor, appearing middle-aged or older with balding gray hair and glasses, stands in the center-right. He wears a dark blue collared shirt and an ID badge on a lanyard. He is actively interacting with students, extending a crumpled white object, possibly a piece of paper, with his right hand towards a student whose raised hand is visible in the foreground. A silver metallic water bottle rests on a light-colored, ribbed wooden lectern to the professor's left. A similar lectern is partially visible to his right, behind which a dark chair holds a dark bag. The foreground is filled with the backs of multiple students' heads, seated in rows, with several laptops open on their desks, indicating an active classroom environment.
