The reading claims that the story of the burning mirror and Roman ships is a myth. However, the lecturer refutes this claim. In the following paragraphs, you will see her reasons to reject this claim.
First, the reading says that these mirrors would have be at least several meters wide, and ancient Greeks did not have enough technological knowledge to make such big sheets of cooper with precise mathematical measures. The professor refutes this claim. She asserts that the ancient Greeks did not need to make a large mirrors. They could have made several smaller ones, and the put them together. They mathematicians had the necessary knowledge to make this kind of mirrors.
Second, the reading says that according to an experiment that was conducted with this kind of mirrors, the Roman ships must stayed with no movement for 30 minutes or more for them be practical. The lecturer refutes this claims too. She said that the aforementioned study was conducted on woods. However, the Roman ships had other materials too. For example, they used some kind of black material to make their ships water proof. In an experiment that was conducted on this material, it was shown that this material needs only several seconds to inflame, and its fire will spread to other part of the ship, very quickly.
Finally, the reading suggests that Greek people of Syracuse did not need the mirror. They have burning arrows, something with the same efficiency in that range. The professor refutes this suggestion too. She said that Roman soldiers were familiar with burning arrows, and they would look for them. They would be ready to put out their fire, but they did not have any kind familiarity with burning mirrors. They would have saw just some mirrors, and then suddenly fire would be on their ships. Something more surprising and more efficient.
