QUES: Hannah Harvey was a ten year old that had many friends in school. She lived in New York and enjoyed doing gymnastics and playing soccer. One day, Hannah came home from school and her parents greeted her. She knew that something was different by the expressions on their faces. Even Jackson, Hannah's dog, was acting different. Hannah asked why everyone was being so strange. Hannah's father, who was known as Pop, explained to Hannah that his job was forcing him to move. Hannah did not seem to think this was too big of a deal. Then, Hannah's mother explained that they were moving to Kenya. Kenya, she explained, was a place in Africa and life would be very different there. As Hannah began to cry thinking about all of her friends at home, Hannah's mother calmed her with a gentle touch. Jackson began howling as Hannah cried, but was also calmed by Hannah's mother. Hannah spent the next two weeks visiting her friends and saying her goodbyes. She did not know the next time she would be home. She cried very hard when she said goodbye to her best friend, Susan. Susan did not quite understand where Kenya was, but promised to visit Hannah. The next day, Hannah boarded a plane with her family. At first, they thought that Jackson could not come with them. However, Hannah worked hard and helped make sure that he had all of his shots so that he could come. After he had them all, the airport said it was OK for Jackson to come! The Harvey family left and off they went across the ocean to begin their new life in Kenya.

QUES: Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit . Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years . Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes . The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold . Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species . The robotic probes sent out to research on Darwin IV are called Horus Probes . Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ' brain ' , a ' head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves . The probes have a limited degree of artificial intelligence , very similar to the ' processing power ' of a 4-year-old . All the real thinking is done by a supercomputer in the orbiting Von Braun . The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker . The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin . After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter .

QUES: Tocqueville asserted that the values that had triumphed in the North and were present in the South had begun to suffocate old-world ethics and social arrangements. Legislatures abolished primogeniture and entails, resulting in more widely distributed land holdings. This was a contrast to the general aristocratic pattern in which only the eldest child, usually a man, inherited the estate, which had the effect of keeping large estates intact from generation to generation. In America, in contrast, landed elites were less likely to pass on fortunes to a single child by the action of primogeniture, which meant that as time went by, large estates became broken up within a few generations which, in turn, made the children more equal overall. It was not always a negative development, according to Joshua Kaplan's interpretation of Tocqueville, since bonds of affection and shared experience between children often replaced the more formal relation between the eldest child and the siblings, characteristic of the previous aristocratic pattern. Overall, in the new democracies, hereditary fortunes became exceedingly difficult to secure and more people were forced to struggle for their own living. This rapidly democratizing society, as Tocqueville understood it, had a population devoted to "middling" values which wanted to amass, through hard work, vast fortunes. In Tocqueville's mind, this explained why America was so different from Europe. In Europe, he claimed, nobody cared about making money. The lower classes had no hope of gaining more than minimal wealth, while the upper classes found it crass, vulgar, and unbecoming of their sort to care about something as unseemly as money; many were virtually guaranteed wealth and took it for granted. At the same time in America, workers would see people fashioned in exquisite attire and merely proclaim that through hard work they too would soon possess the fortune necessary to enjoy such luxuries. Despite maintaining with Aristotle, Montesquieu, and others that the balance of property determined the balance of power, Tocqueville argued that, as America showed, equitable property holdings did not ensure the rule of the best men. In fact, it did quite the opposite. The widespread, relatively equitable property ownership which distinguished America and determined its mores and values also explained why the American masses held elites in such contempt.

MY QUESTION: Why were the children of American elites more equal to non-elite children than were the children of European elites?

QUES: Sound waves are mechanical waves. They can travel only through matter. They cannot travel through empty space. This was demonstrated in the 1600s by a scientist named Robert Boyle. Boyle placed a ticking clock in a sealed glass jar. The clock could be heard ticking through the air and glass of the jar. Then Boyle pumped the air out of the jar. The clock was still running, but the ticking could not be heard. Thats because the sound couldnt travel without air particles to transfer the sound energy. Is there any other place where sound cannot be heard? Here is a hint: is there any other place that does not have air molecules? Thats right, in space sound cannot be transferred. So can astronauts hear each other? Yes, they can, because they are in enclosed space stations or pressurized suits.In both cases, they are surrounded by air molecules. If they left their space ship and did not use their electronics, they would not be able to hear each other. Next time you watch a science fiction movie, think about this factoid. When spaceships are destroyed by hostile alien beings, there would be no sound heard. Sound waves can travel through many kinds of matter.
