Summarise the points made in the lecture, being sure to explain how they case doubt on specific points made in the reading passage.
The reading and the lecture are both about ancient Greek's use of "burning mirror" to defend themselves from a navy attack of Romans. The author of the reading feels that it was just a myth and Greeks of Syracuse never used them. The lecturer challenges the claim made by the author. She is of the opinion that this weapon was actually used.
To begin with, the author argues that the Greeks then were not technologically improved enough to build this type of weapon. The argument mentions that it would require a very precise parabolic curvature, which will need a large sheet of copper. This specific argument is challenged by the lecturer. She says dozens of small copper pieces could have been used to produce the same result. Additionally, she describes that, the mathematical knowledge of the Greeks were sound enough to produce a precise curvature of parabolla.
Secondly, the writer suggests that burning with this weapon would have taken a long time. In the article, it is stated that a wooden object takes 10 minutes to burn with the help of that weapon. The lecturer, however, refutes this by mentioning that there were other parts of the ship which were not wooden. She elaborates on this by bringing up the point that there was a substance called pitch that would fire up within seconds after the sunlight had been concentrated on it.
Finally, the author posits that Greeks were already using flaming arrows that were producing the same result. Moreover, in the article, it is stated that "burning mirror" would not have been considered as an improvement to arrows. In contrast, the lecturer's position is that this weapon would have been better in the sense that they have an element of surprise. She notes they are better as they are not as predictable as arrows.
