I know that this is a wonderfully generous free online course and thus one should perhaps operate with an understanding of there being some imperfect information, but there are so many ambiguities, discrepancies and errors in the first video of the history module that I have to comment on it. I also noticed some very poor writing in both the subtitling and text, and Ben has clearly chosen the wrong emphasis and cadence in several sentences, which adds to the confusion, I won't say anything further about the grammar and syntax employed, but I would urge you to review this module.
1. What does Ben mean when he states that the sites of Stonehenge and Newgrange were 'proven' to have connections to the civilisations of Myenea, Ancient Greece and Egypt? Is he referring to a common preoccupation with astronomy and the movement of celestial bodies? Is it accurate to call this a connection? Who has proved this? How?
2. First of all, Pythagoras was born in the 570s BCE, not around 500BCE, that's 70 years difference and the fact that you have a slide with the accurate date on it visible whilst Ben is talking only serves to highlight this discrepancy. Also, what on earth is Ben talking about with claiming that Pythagoras' theory of light one based on 'feelers' travelling from the eye to the object? He has this exactly wrong. Empedocles was the first one who articulated some rudimentary concept of 'emission theory', wherein light is cast from the eye to the object. Pythagoras was in fact an early proponent of what became 'intro-mission theory', which postulated that objects cast off images which were then captured by the eyes. This is not even a mild error, this is just flat out wrong.
3. Aristotle was born after Mo Ti died. They were certainly not born around the same time. There wasn't even any chronological overlap. This would be the same as me saying that Galileo and Newton were born at around the same time. Also, I know this is a brief clip and so brevity is the idea here, but it's also not strictly accurate to describe Aristotle's conception of light as being in the shape of waves, he did have an influence on later optical theoreticians who developed wave theory, but he was personally more invested in the idea of an invisible ether through which light moved.
4. 'Wayang' is an Indonesian word! Not an Indian one! 'Indian' isn't even a language!
I don't want to bombard you with criticisms, on the whole I think this is a wonderful idea, but I think it would do your course a great service to go back and review your sources. If you rewrite your text and ensure that the clip you put up is not only factually accurate, but is also easily understood and well-written, I believe you would have a much stronger module. :)
