Listen to a part of talk in astronomy class.

The origin of earth moon the largest moon in a solar system is still something of a mystery. There are some theories about its origin however. Now keep in mind that the theory of the moon origin has to be consistent with two important facts. The first fact is that the earth contains a lot of iron, most of it has an iron core, but the moon contains practically no iron. The second fact is that other than the different iron content, the moon in earth are composed of essentially the same minerals, a similarity not shared with any other plant or moon in our solar system. One of the earliest theories of the moon origin, I call it the capture theory, proposes the moon was somehow captured by earth gravitational force. This theory is improbable however because it assumes that the moon on earth formed in different parts of the solar system. If this were true, you would expect the moon's composition to be much different from earth's composition, just as all the other planets in the solar system are so different from earth. A second theory of the moon's origin is more promising. It is sometimes referred to as the mars theory because according to this theory, when earth was still motton, it was struck by a planet about the size of mars. The impact caused the cores of the two planets to melt together and chunk the earth crust to be thrown out into space. These chunks came together to form the moon. Now remember earth crust is low in iron, because the iron is in earth core, but high in various other minarals. This sign accounts for why there's little iron but lots of other minerals on the moon.

Humen populations near the equator have involved with dark skin over many generations，because the expousure to the fierce raze of the sun. A similar phenomenon has also occurred in another part in the animal kinge. The african grass mouse is a good example. Most mice are not ternal, but the african grass mouse is active during daylight hours. This means that the sentive days searching for food in the semidrive bush in scribe have a tack in eastern and southern Africa. It xx like a cheek mouse, which help they gland in with the environment. Because it spends a lot of time in the intence tropical sun, the grass mouse has also involved two separate safe guard to against the sun's untroviolence radiation. First, like the population of human that xxx  in the world, the skin of the mouse contains lots of the meloment or dark pigment.Second and quite unusual, this mouse has the layer of meloment in pigment tissue  between the skou  and skin. This unique cap provide the xx protection for the grace mouse and 3 other types of african mouse like rotton that are active during the day. The only other spiece scientists identified was the same sort of scale the adaptation is the quite type making back of the central american tropics. Although these backs please during the day, they do so crode up with their head expoused to the sun.

Listen to a talk by a marine biologist in an aquiriam.
Welcome to our aquiriam. As we begin our tour, the first animal will see today is the starfish. You probably will have seen the picture of the starfish. But in a few minutes, you'll see some live ones, and learn a little about of their structure and life psycho. first of all, the star fish is not fish. They belong to the family of the akindiderm, which are spiny skinned sea animal.That is, their skin is covered with thorny bomp. Most starfish have five arms like extensions of their bodies, so they look like a five pointed star. But some other kinds have is many sporty your more arms. Starfish, like other members in the akindiderm family, have called radio symmetry. All that means is that their body parts of the animals are arranged around the center, kind of like oak of the wheel around the hub. One of the special features of the starfish is that it can drop off arms as a defensive reaction, to get away from an attacker, for example. They can then grow new arms to replace the old ones. Starfish reproduce by releasing eggs into the sea. These eggs develop into larvy and can swim freely. These early forms preture what larvy are, differ from adult starfish, because the larvy have by lateral symmithry. That means that the two heads of the starfish look exactly the same, which make them a lot different from the later form of the starfish. Eventually, the larvy sink to the ocean bottom and change and adopt radio form. If you don't have any question, we'll go in now and see some of these creatures in person.

Listen to a part of talk in a physics class.

Ok, even if we've been talking about mechanics, then we still have a few minutes. Let me tell you a little about the ancient Greek and what they thought about mechanics. They came up this system mat for them into describe and explain the different motion of different matirial. More than 2000 years ago, Aristotle, the antient Greek philosipher, assumes that all the matter on earth was made up of 4 prime substances, earth, water, iron, siren. Under this system, earth is the stancest, water is next, iron is less stancen water ,and siren is the least stance of all. The heavist object was made of first into water, and the lighter object contains significant into fire or air. So when Aristotle observed that different types of matter have different characteristics, he assumes that this was because the different types of matter were composed of different amount of the 4 primary substances. And Aristotle believes that the motions of object could also be explained by the basic natures of the 4 substances. Um, for example, there was a basic motion of up or down. Aristotle noticed that when he released most objects, they would drop downward. But he also noticed that something would rise upward, like smoke. Aristotle considered that the object downward or upward motion to be result of the nature of the object. So according to Aristotle, matters like rocks were primarily composed of earth, therefore they naturelly wanted to move towards the center of earth, because this was where all things were rested. But fire has a different resting place, the sky. The smoke was naturally rise when it was release, because it was striving for its natural resting place.

Listen to a part of a talk in a literature class. The professor is discussing the poetry of ancient Greece.
We are gonna start our discussion of poetry in Western Europe with the I and the O. These two great poems stand out as great examples of the earliest therapy in poem. They are believed to have been return sometime between 800 B.C. and 700 B.C., probably because the poems referred to the social condition of that time. Conditions that have been validated by the fining xx of the archeologist. But just two was the poet who laid down these corner stones of western literature. Well, tradition ascribed them to a man named Homer. But we know virtually nothing about this Homer, in fact, some state that such a poet never existed at all. That need of the I nor the O was written by a single poet, but rather each poem is a compositive of the writing of several people. This, anyway, was the view of a school of literary creatics 18 century, known as the analyze. The analyze pointed to internal evidence, such as very ancient in the library devices using the poem, to argue that each work was in fact a collection of several poems by several gregothers. A pose in the analyze was a second group of scholars calls the Unitarian. They insisted that I in the O could well have been the work of a single polemic genius. To support their argument, they stressed among other thing, the consistency of the characters betrayed in the stories. This would have been impossible, they said, if they were written by many different poets. Now how we look at the whole American question today has been greatly influenced by someone named MP, an American scholar first presented his idea about the homer in the 1930s. So let's take a look at Paris research and how it affects what modern day scholars think of Out Homer.

Listen to a part of a talk in a music class. The professor is discussing a musical theater production.
It may seems strange that we are discussing music from Broadway production in the next class, the Lion King especially, since it's based on a popular Hollywood movie. I mean, music be formed for Broadway theater in the heart at New York city, surly would seem to be in the western tradition of popular music, and not have much in common with the music we've been studying in the course. Such as G music in A, or Z in south africa,music get to develop outside of the western tradition of European and America. But in fact, musician have a long standing tradition of borrowing from one another cultures. And this production ?? intentionally include both western and nonwestern music. That weighs some of the reason. Instruments, harmonies, typical of nonwestern music contrast with the incomplement popular music more familiar to ordiences in north America in Europe, music like rock jazz, or Broadway style showtune, so i'd like to spend the rest of this class and most of the next one on the music from the show the Lion King as a way of summarising some of the technical distinctions between typical western music and nonwestern music that we've been studying. Now the african xx in songs is clear. the story takes place in africa, so the director got a composer to write songs which is distinctly africa sound, and the songs even include various from african languages. But work exactly african into flater. first, let's turn to the music that was written for the shadow puppet things in the Lion King. music based on the indernition music used the shadow puppet theater of that region.

Listen to a talk in a biology class.
This morning I want to tell you about a recent scientific discovery dealing with the relationship between plants and animals. This is about a desert shrub, whose leaves can shoot us extreme a poison and ......a distance of 6 feet. you think it'll be safe from all attack by infect. but a recent study has found one infect, a beatle, that can choose its way path the plan ...system by cutting the main vim that delivers the poison to the leaves. This vim cutting is just one methods that the beatles use to prepare its safe meal. Another is by cutting a path all the way across the leaf to hold the fluid chemical. Then they simply eat between the vim to avoid the poison. in the past, scientists who studied in the adaptation to plan defenses, have focused on the chemical responses. That is how the infect can neutralize or all to the poison ... substances plan for duce. What is unique about this chewing strategy, is that the beatle is a actually exhibiting a behavioral response to the plan's defenses, rather than the more common chemical response. it is only actor a beatle survive several encounters with the plan resent learn how to avoid poison by chewing through the resent transporting vims on the next fleet ... and thus get itself a safe meal. However, it can take a beatle an hour and a half of careful vim cutting to prepare a small leaf that takes it only a few minutes to eat. So, though the method is effective, it's not very efficient.

Listen to a talk in a biology class. The professor is discussing insect behavior.
Today we are going to continue our discussion of social insects, focusing on the Argentina ants, which as you may guess, is a species of ants that is native to Argentina. We’ll consider what happened to this type of ants after some members of the species moved to California from their original habitat. Ok, well, in Argentina, these argentine ants behave like most ant species around the world. They fight other ants of the same species if those ants are from some other nest. but the argentine ants living in California behaved differently. Ants from different nests form a single large colony. Within this colony, there is little aggression among ants from different nests. And when they fight insects from outside the colony, the argentine ants can quickly recruit a huge army from their network of nest. This of course will give some advantage over other ant species. So then, why do argentine ants behave differently in California than they do in Argentina? Well, using genetic testing, researchers found that all the argentine ants in California were very similar genetically. You see, when the first argentine ants came to California, their population not to have been very small, and all the later generations of argentine ants there must be descended from the same few ancestors. So, they are all closely related. This discovery is important because for most social insects, membership in the colony is based on how closely related they are genetically.

Listen to a part of a talk in a biology class.
We’ve been looking at fear from a biological perspective, and someone asked whether the tendency to be fearful is genetic. Well, some studies done with mice indicate that animals do in xx have fearfulness to some degree. in one study, for instance, a group of mice were placed in a brightly open box with no hiding places. Some of the mice wandered around the box and didn't appear to be bothered about being so exposed. The other mice didn't move. They stayed out against one wall, which indicated that they were afraid. well, when the fearful mice or you might say, anxious mice, like the one who stayed in one place, when mice like these was spread one and another repeatedly, after about 12 or so generations, then all of the the off-spring showed similar signs of fearfulness. and even when a new born mouse from this generation was raised by a mother and with other mice who were not fearful, that mouse still candid to be fearful as an adult. Now, why is it? Well, it's thought that the specific genes in animal's body have an influence on anxious behavior. These are genes that are associated with particular nerve cellary(?) receptors in the brain. And degree of overall fearfulness in the animal seems to depend in large part on the presence or absence of these nerve receptors. And this appears to apply to humans as well by the way. But while a tendency towards anxiety and fear may well be in xx trait, this specific form that the fear take has more to do with the individual environment. So, a particular fear, like the fear of a snake, or the fear of a spider, say, is not genetic, but the overall tendency to have fearful responses is.

Listen to a part of a talk in the United States history class. The professor is discussing the Civil War.
Last time, we outlined how the civil war finally got started. I want to talk today about the political management of the war on both sides, the north under Lincoln, and the south under Jefferson. An important test for both of the presidents was to justify for their citizens just lie the war was necessary. In 1861, on July 4th, Lincoln gave his first major speech in which he presented the northern reasons for the war, and what he said to preserve the democracy. Lincoln suggested that this war was a noble crusade that would determine the future of democracy throughout the world. For him, the issue was whether or not this government of the people, by the people could maintain its integrity, could it remain complete, and survive it demotic both. In other words, could the a few discontented individual and by that he meant those who led the southern rebellion, could they arbitrarily break up the government, and put it into a free government on earth. The only way for the nation to survive was to crush the rebellion. at the time, he was hopeful that the war wouldn't last long and this label xx would be put down forever. but he underestimated how difficult this war would be. It would be harder than any the American supported before all since, largely because the north had to break the will of southern people, not just by the army. But Lincoln rally northerners to a deep commitment to the cloth. They came to perceive the war as a kind of democratic crusade against southern society.

Continuing our survey in the 19th century, let's take a look at now HBS. Now still in best known for her novel uncle tom Kevin, a book that details the harshness of plantation like in the south. The book is extremely popular in the United States as well as in other country. Ironically, for all the attention given to Uncle Tom Kevin, it is far from Stone's best work. She did write one other novel about the life in the south. But much of her best work has nothing to do with the south at all. In fact, Stone's best writing is about the village life in the New England State in the 19th century. In recording the customs of the villages she wrote about, Stone claimed that its purpose was to reflect the really...possible. She usually succeeded for her setting her often describe accurately and in detail. In this sense, she was an important forerunner to the realistic movement that became popular later in the 19th century. She was one of the first writers to use local dialects for her characters when they folk. And she did this folks for 30 years before Mark Twin popular to use the folk dialects. It makes sense that Stone was write about New England life and she is born K. As a young woman there, she worked there as a teacher. The teaching job helped lead to her first published work, a geography book for children. Later when she was married, her writing helped her to support her family financially. Throughout her life she wrote xx, travel books, biographical sketches in children's books as well as novels for adult.

Listen to a part of a talk in xx communication's class.
Let’s turn our focus now to advertising. We all know what an advertisement is; it's essentially a message that announces something for sale. Now, there is important 3 conditions as much exist before you have advertising. And that's a large supply of consumer goods, that is, things for sale. You see, in a place where the demand for the product is greater than the supply, there's no need to advertise. now the earliest forms of advertising going back many hundreds of years were the simple sign over shop doors that told you whether the shop was a bakery or put you shop where would help you. Then will be advent in printing crease. Advertising in crease, substantially, as for product like coffee, tea and chocolate, a period in newspapers in other parietals, as well as the signs of the building. In the American colonies, advertising in communication's media like newspapers and paxx, became a major factor and marketing goods and services. By MS, this early advertisement was quite small and subdue, not the splashy whole page today. Still, some of them appear in the front page of newspapers, probably because the news often consisted of less and fresh report from distant Europe or the ads were currently local. Advertising really came in and do it soon and became an essential part of doing business during the Industrial Revolution. Suddenly there was much greater supply of things to sell. And that's what we said earlier, that is the driving force behind advertising. People’s attention had to be drawn to the new product. Let’s take a look at some of the advertisements from that time.
