summarize the points made in the lecture, being sure to explain how they challenge the points that why Greeks never built burning mirror to burn the Roman ships mentioned in the reading passage
In the reading passage, the author discusses that burning mirror is just a myth and the Greekes of Syracuse never really built such a device to burn the Roman ships, while the lecture claims that what the passage state is not convincing and disputes those ideas presented in the passsage with several proofs.
Firstly, according to the reading passage, it is suggested that the ancient Greeks not technologically enough to make such a device because the mirror should have to be several meters wide and have a very precise parabolic. In contrast, the professor argues in the lecture that a burning mirror could be made with dozens of small individually flat pieces of copper instead of a large single sheet of copper. Moreover, the Greeks knew the properties of the parabola and thus they could direct the assembly of small mirror pieces into the burning mirrors.
In addition, the statement in the reading material indicates that the burning mirror would have taken a long time to set the ships on fire. The experiment had shown that the device concentrating the Sun's rays on a wooden object 30 meters away took ten minutes to set the object on fire and the object had to be unmoving during that time. On the contrary, the professor points out that the experiment just tested the wood maternial which was on fire needed ten minutes. However there is another materinal called pitch that would get fire quickly within seconds. Once it catches fire, it would rapidly spread to other places.
Finally, the author of the reading claims that the Greeks already had flaming arrows so that they had no reason to build a weapon like a burning mirror. However, the speaker argues that burning mirror to be more effective. Roman soliders were familiar with flaming arrows and knew how to deal with them, but they could not see the burningrays form a mirror and would be surprised at when and where the fire would start.
