To watch the video, click the play button (arrow).

Closed Captions (subtitles) are available on this video. To view them click the (CC) button at the bottom right-hand corner of the video screen and select 'English'. AI-generated captions are available in other languages as well, but I can't guarantee their accuracy.

When you have finished watching the video click the green 'complete and continue' button* at the top of the screen to move to the next lecture.

*If you are on a mobile device the green button will simply have an arrow on it.
