Time seems to slow as it approaches us, and living in the post-Cold War nuclear age, we should remember that the past feels distant even when it's near, and that the future seems assured even though it isn't. Thanks for watching. I'll see you next week. Crash Course is produced and directed by Stan Muller. Our script supervisor is Meredith Danko. Our associate producer is Danica Johnson. The show is written by my high school history teacher, Raoul Meyer, and myself, and our graphics team is Thought Bubble.
