TPO-30 Integrated Writing

A little over 2,200 years ago, the Roman navy attacked the Greek port city of Syracuse. According to some ancient historians, the Greeks defended themselves with an ingenious weapon called a "burning mirror": a polished copper surface curved to focus the Sun's rays onto Roman ships, causing them to catch fire. However, we have several reasons to suspect that the story of the burning mirror is just a myth and the Greeks of Syracuse never rally built such a device.

First, the ancient Greeks were not technologically advanced enough to make such a device. A mirror that would focus sunlight with sufficient intensity to set ships on fire would have to be several meters wide. Moreover, the mirror would have to have a very precise parabolic curvature(a curvature derived from a geometric shape known as the parabola). The technology for manufacturing a large sheet of copper with such specifications did not exist in the ancient world.

Second, the burning mirror would have taken a long time to set the ships on fire. In an experiment conducted to determine whether a burning mirror was feasible, a device concentrating the Sun's rays on a wooden object 30 meters away took ten minutes to set the object on fire: and during that time, the object had to be unmoving. It is unlikely that Roman ships stayed perfectly still for that much time, Such a weapon would therefore have been very impractical and ineffective.

Third, the mirror does not seem like an improvement on a weapon that the Greeks already had: flaming arrows. Shooting at an enemy's ships with flaming arrows was the way of setting the the on fire. The burning mirror and flaming arrows would have been effective at about the same distance. So the Greeks had no reason to build a weapon like a mirror.

The reading part and the lecture both discuss a weapon that Roman Empire used to set a fire. In the reading passage, the author mentions that the story of 'burning mirror' is a myth and could not exist for three main reasons. In the listening part, however, the speaker challenges what the author states and rebuts the reasons, inconvincing enough.

To begin with, as mentioned in the article, the author points out that they were not technologically advanced adequetaly to chieve this instrumente. In the listening part, nevertheless, the professor refutes the reasons asserting that they utlizied polish copper and with new metal and small peace of mirrores , they could make it.

Secondly, the author sets forth that should they want to set a fire on ships, they should stable the ship for minutes and it did not posssible on that time. Nonetheless, the speaker, flatly contradicts the idea and contends that they used to set wood and it took ten miniutes to lit, in contracts they used another material so-called pich to cash fire insted of woods and it could set on fire on mirrior by a second and it was quieqly enough to be on ships.

Finally, the author claims that it was not a important weapons on that time and thety use arrows and it was much more capable than this. In contrast, the professor is of the opinion that their enemies know arrows and they use the morror for surprising them and it was much effective that arrows, because the mirrore just took thier attention and they could use arrows bether on that conspets.
