Lecture Lens

Follow a lecture without losing the thread.

Press Start listening and let the lecture play.

1. The transcript appears here as the lecturer speaks.
2. A term this course has not used before is highlighted, with a one-line definition under it.
3. Every new term also collects on the right, so you can look it up without searching the text.
4. Lost the thread? Press I'm lost: it explains how the last few terms fit together.
