I noticed some mistranscriptions in the transcript (subtitles, captions) for the course videos. Below is the errata for the 4th week. I’ll post the errata for the other weeks in those groups.

The format for the errata is as follows. The approximate time is in braces, then the mistranscribed word or phrase follows, followed by a hyphen, then followed by the correct word or phrase. Like this:

[time] mistranscribed word or phrase - correct word or phrase
