What does the author explain about the SAR sonar
tracking system?
SAR finds objects underwater by bouncing
electronic sound waves off of them.
We had used Jean-Louis' brand-new SAR system, a sonar
tracking instrument that looked like a red torpedo. But
we had not found anything. We had covered a lot of
ground, but the ocean currents had been very strong.
They had often pushed us off course, wasting precious
time. Already we were behind schedule. Sonar is used to
find underwater objects by bouncing electronic sound
waves off them.

Red torpedoes were used to track the objects on
the ocean floor.
The strong ocean currents wasted time, keeping
the scientists behind schedule

Explanation:

to kill a mockingbird basically is about a lawyer who goes against everything in a racist society like at the time of this novel, to defend a black man accused of sexual abuse. in the bible there are cases like that of joseph, who was accused by the woman of potifar, for a crime similar to that of tim robbinson, of that novel (genesis 39: 1-20). at this point we see that god also provides the escape to joseph, who was accused unjustly, but in his time, and through his attitude, his faith was not shaken, and god provided the solution. the perspective of god also written in the bible and not pay evil with evil. (ephesians 4: 32, 1 thessalonians 5: 15, 1 peter 3: 9). atticus, the lawyer, demonstrated during this lee novel, empathy, love of neighbor, understood the situation of this accused man. he went against everything in that society, and stood in favor of that man, for the injustice committed. this shows the empathy, the love taught by christ, in some passages that speak of love and justice in the sermon of the beatitudes (especially verses 6 and 7 of matthew 5).

recent brain research has shown some surprising benefits as a result of formal musical training. learning to play a musical instrument appears to develop parts of the brain that can even influence academic results. the studies indicate that the earlier a child begins training, the more benefits there are. one such study showed that children who began musical studies before the age of seven had a more developed brain in the region where language production and auditory processing take place. scientists believe there is mounting evidence to show that early musical training can improve brain function.
