At 1:44 video shows interceptions and audio says the same, But it should be intersection.

website should have text box below video, just like youtube description, so that any such typo/errata or any further explanation can be pointed out to learners. As with time and increase in number of courses, the errata cannot be eliminated at each point and question related to same errata would come again and again in questions. Hence, implementing any text box below would significantly reduce such questions and would also help to post any additional information related to particular video.
