The reading and the lecture are about the possibility that the Greek used polished copper curved surface to focus the light of the sun on the invading Roman's ships. The reading rejects the theory that the Greek were able to produce such weapons for many reasons, but the lecturer supports this hypothesis by casting doubt on all the reasons mentioned in the reading. The lecturer provides three evidence to support his argument.
First of all, the reading states that the Greek were not advanced enough to produce such large mirror sheet. The lecturer, however, rebuts this claim by suggesting that the Greek may have used many small mirrors instead of big sheet mirrors.
Second, the author of the reading says that during an experiment of examining the effectiveness of using such mirrors to burn a wooden body, it needed at least ten minutes on fixed object to burn it which was impossible in the real battle since the ships kept moving during the whole time. The lecturer, on the other hand, argues that the bodies of the ships were not only made of wood, but also form sticky substance called pitch that is liable for burning in just seconds of exposing to the high intense heat coming form the mirrors.
Third, the reading draws our attention to the fact that the Greek already had effective weapons like the flaming arrows, so they didn't need any other weapon. The lectures rebuts this claim by explaining that the Roman also were familiar with the flaming arrows and they certainly took precautions against them. In contrast, the mirror weapon would be something that is completely new and surprising to them which would make it a very strong effective weapon.
