Harvard CS50 (2026) – Full Computer Science University Course - Transcript [EN]

The video is an in-depth lecture from Harvard CS50 Week Zero, introducing core computer science concepts using accessible storytelling. David Malan walks through how information is represented as zeros and ones, bases like binary and decimal, Unicode, colors, and media, and the role of algorithms and abstraction. The session includes live demonstrations in Scratch and Scratch-based projects to illustrate building blocks, functions, conditionals, and loops. It emphasizes problem solving, programming fundamentals, and gradual abstraction from low-level hardware to high-level coding concepts. The talk also previews tools and environments like VS Code and Scratch to scaffold learning throughout the course.
