Dialogue: 0,0:00:17.70,0:00:22.33,Default,,0000,0000,0000,,Computer science is just learning \Nhow a computer works and how it thinks,
Dialogue: 0,0:00:22.33,0:00:24.70,Default,,0000,0000,0000,,so that you can teach it to do new things.
Dialogue: 0,0:00:24.80,0:00:28.10,Default,,0000,0000,0000,,These days what you can do in computer science \Nis pretty much amazing.

Dialogue: 0,0:01:30.30,0:01:33.90,Default,,0000,0000,0000,,I'm going to choose the "turn right" block and I'll drag it underneath
