Mk5sf8x [font=Times New Roman]I hope you have all finished reading the assigned chapters, so that [color=red]you’re prepared [/color]for discussion today, but before we start, I’d like to mention a few things your[color=red] text [/color]doesn’t go into. It is interesting to note that the insurance has existed in some form for a long time. The earliest insurance policies were what we called [color=red]bottomry contracts[/color]. They provided shipping protection [color=red]for merchants[/color] as far [color=red]back [/color]as 3,000 BC. In general, the contracts [color=red]were[/color] often no more than verbal agreements. They granted [color=red]loans[/color] to merchants with the understanding that if a particular [color=red]shipment [/color]of goods were lost at sea, the loan didn’t need to be repaid. Interest [color=red]on[/color] the loans [color=red]varied[/color] according to how risky it was to transport the goods. During periods of [color=red]heavy privacy[/color] at sea, for example, the [color=red]amount[/color] of interest and the cost of policy went up considerably. So you can see how insurance helped encourage international trade. Even the most [color=red]cautious merchants [/color]became willing to risk shipping their goods over long distances not to mention in [color=red]hazardous[/color] weather conditions, when they have this kind of protection available. Generally speaking, the basic form of an insurance policy has been pretty much the same since the Middle-Ages. There are four points that were [color=red]salient [/color]then and remain[color=red] paramount [/color]in all policies today. They were [color=red]outlined[/color] in chapter 6 and will serve the basis for the rest of today’s discussion. Can anyone tell me what one of those points might be?[/font]

^ c,C8CTC4e#i8\ [font=Times New Roman]Current studies show that[color=red] what [/color]goes on labels is an important consideration for [color=red]manufacturers[/color], since more than [color=red]70[/color] percent of shoppers read food labels when considering whether to buy a product. A recent[color=red] controversy[/color] [color=red]as to[/color] whether labels on prepared food should educate or merely inform the consumer is over and consumer group got its way. The group had maintained product labels should do more than simply list how many[color=red] grams of nutrients[/color] a food contains. Their [color=red]contention[/color] was that the labels should also list the [color=red]percentage [/color]of a day’s total nutrients that the product will supply to the consumer, because this information is essential in planning a healthy diet. A government [color=red]agency [/color]disagreed strongly, favoring a label that merely informs the consumer, in other words, a label that only lists the [color=red]contents of [/color]the product. The agency maintained that the consumers could decide for themselves[color=red] if[/color] the food is nutritious and [color=red]is meeting [/color]their daily needs. The consumer group, in supporting its case, has [color=red]cited [/color]a survey in which [color=red]shoppers [/color]were shown a food label and[color=red] were then asked [/color]if they would need more or less of a certain nutrient after eating [color=red]a serving of[/color] the product. The shoppers [color=red]weren’t [/color]able to answer this question easily when they were not given a specific [color=red]percentage[/color]. This study and others helped get the new regulation passed, and now food products must have the more detailed labels.[/font]i

9G.m6A~8}+E fiR [font=Times New Roman]Thank you all for [color=red]coming out[/color] this evening to meet sociologist L. Mr. L [color=red]specializes [/color]in research on work place and recently has been writing about the future of the work. This topic would [color=red]be of [/color]special interest, since I know many of you are already [color=red]at the forefront of workplace[/color] technology. For example, let’s have [color=red]a show of [/color]hands to see how many people here telecommute at least part of time. Hmm, I see eight hands raised. You eight[color=red] folks[/color] who work at home [color=red]and [/color]communicate with your office via computer represent one of the trends Mr. L has described: that people are becoming less tied to the workplace. One of the important tools for telecommuting is electronic mail or Email. Email lets you send and receive messages immediately [color=red]on your computer[/color], but you can control when you read them and when you respond to them. This technology allows people have more control over time than[color=red] when relying[/color] solely on telephone. Our guest tonight will discuss how [color=red]these[/color] important changes will alter the way we work. But before turning the floor over to Mr. L, I would just like to remind you tha[color=red]t she will[/color] be available to answer any individual questions [color=red]at the [/color]reception immediately following [color=red]this talk.[/color][/font]

[font=Times New Roman]Today, I’d like to turn our attention to [color=red]an area of[/color] management often [color=red]overlooked[/color] in traditional management courses- small business management. Small businesses have [color=red]gone[/color] from small town stores selling food or clothing to [b]sophisticated[/b] high-tech [color=red]enterprises[/color]. [color=red]And[/color] in addition to the important products they produce, they create jobs [color=red]for [/color]lots of people because there are so many of them. It is important for the management to keep in mind [color=red]which of [/color]the customers’ [color=red]needs [/color]the [color=red]business[/color] serves, because they [color=red]can’t [/color]serve all their needs. Writing a business plan that everyone in the [color=red]organization[/color] understands and follows will help [color=red]to [/color]provide necessary focus and [color=red]direction[/color]. It is important to[color=red] state [/color]clearly what the purpose of the business is. Additionally,[color=red] each person [/color]within the organization [color=red]must[/color] know [color=red]what tasks [/color]to perform in order to fulfill that purpose. Now, [color=red]if for[/color] some reason, the plan of the business doesn’t work, try hard to [color=red]discover [/color]why not, rewrite it and immediately focus on the new plan. [color=red]A work of caution[/color], however, never gives up a bad plan without replacing it. A business has to have a plan, because it can’t afford to waste its limited resources. And as you know, waste leads to unnecessarily high production costs. Production costs are at the heart of the company’s ability [color=red]to make a high quality[/color] product and sell it at [color=red]an affordable [/color]price.[/font]

InteriorC'PF+Bg%@*hax{
I am glad you bring up the question of our investigations into the makeup of the earth’s interior, in fact, since this is the topic of your reading assignment for next time. Let’s spend these last minutes of the class talking about it. There were several important discoveries in the early part of this century that helped the geologists develop a more accurate picture of the earth’s interior. The fist key discovery had to do with seismic waves. Remember, they are the vibrations caused by earthquakes. Well, scientists found that they traveled thousands miles through the earth interior. This finding enabled geologists to study the inner parts of the earth. You see, these studies revealed the vibrations were of two types, the compression or P waves and shear or S waves. And researchers found that P waves travel through both the liquids and solids, while S waves travel only through solid matter. In 1906, a British geologist discovered the P waves slow down at certain depth but kept traveling deeper. On the other hand, the S waves either disappeared or were reflected back, so he concluded that the depth marked a boundary between a solid mantle and a liquid core. Three years later, another boundary was discovered that between the mantle and earth crust. This is still a lot to be learned about the earth. For instance, geologists know the core is hot. Evidence of this is the molten lava flows out of the volcano. But we’re still not sure what the source of the heat is.3d] G?X J

Today, I want to talk about the earth’s last major climatic shift at the end of the Ice Age. But first let’s back up a moment and review what we know about the climatic change in general. First, we defined climate as consistent patterns of weather over significant periods of time. In general, the changes in climate occur when energy balance of the earth is disturbed. Solar energy enters the earth’s atmosphere as light and is radiated by the earth’s surface as heat. Land, water and ice each affects the energy exchange differently. The system is so complex that, to date, our best compute models are only crude approximation and are not sophisticated enough to test the hypotheses about the causes of the climatic change. Of course, that doesn’t keep us from speculating. For instance, volcano activity is one mechanism that might affect the climatic change. When large volcanoes erupt, they disperse tons of particles into the upper atmosphere, where the particles then reflect the light. Since less light is entering the system of energy exchange, the result will be a cooling of the earth’s surface. Of course, this is just one possible mechanism of global climatic change. In all possibility, a complete explanation would involve several different mechanisms operating at the same time.

IxV(F9pE(md I’d like to begin by thanking Doc. K for inviting me to be here today. Although I am not a geologist, I have been collecting minerals for years. My collection is very diverse, because I’ve traveled all over the world to find them. Today, I’ve brought a few specimens for you see. After I discuss each one, I’ll pass it around and so that you can look at it more closely. As you know, feldspars are the most abundant minerals and are divided into a number of types. These first samples are orthoclase. Notice that they vary in colors, from white to pink and to red. This glassy one is found in volcanic rock. In fact I found it in New Mexico on a collection trip. The next sample I will pass around is a microcline mineral, also called amazonstone. You can identify it by its bright green color. It is often used in jewelry and really is quite attractive. The final samples are plagioclase feldspars. Many plagioclases are very rare. So I am particularly proud of the variety in my collection. I have also brought a few slides of some large mineral samples. And if you’ll turn out the lights now, I would like to show them to you.v'? A5Qq8QzK

Fossil fuels
!E%aR7H D Today, I’d like to discuss fossil fuels, such as coal, oil and natural gas. The term fossil fuel refers to the trapped remains of plants and animals in the sedimentary rock. You see, living plants trap energy from the sun by the process of photosynthesis, and they store the energy in their chemical compounds. Most of that energy is released, when the plant dies and decays. However, sometimes organic matter is buried before it decays completely. In this way, some of the solar energy becomes trapped in rocks hence the name fossil fuel. Although the amount of the organic matter trapped in any one growing season is small, the accumulated remains for millions of years are considerable. Because the accumulation rate is so slow, millions times slower than the rate at which we now dig up the organic matter and burn it for energy, we must consider fossil fuels as nonrenewable resources. Tomorrow we’ll be discussing alternatives to fossil fuels that can be renewed.

[font=Times New Roman]Not long ago, some of you may have read about a team of mountain-climbing scientists who helped to [color=red]recalculate the elevation[/color] of the highest mountain in the world- Mt. Everest. Of course, the elevation of Mt. Everest was determined many years ago, using traditional [color=red]surveying [/color]methods. But these scientists want to make a more precise measurement, using a new method [color=red]takes advantage of recent advances[/color] in technology. It is called global positioning system. The global positioning system uses 24 [b]satellites[/b] that [b]circle [/b]the earth. Each of these satellites is constantly sending [color=red]out [/color]signals. And [color=red]each[/color] signal contains important information that can be used to determine the longitude, latitude, and elevation [color=red]of [/color]any point on the earth’s surface. Well, in order to use this system to calculate the Mt. Everest[color=red]’s elevation[/color], the scientists needed to put a special receiver on [color=red]its[/color] summit to receive signals from the satellites. The problem with this was that: in the past, the [color=red]receivers were[/color] much too heavy for climbers to carry. But now these receivers have been reduced to about the size and weight of the [color=red]handheld [/color]telephone. So the climbers were able to carry a receiver to the top of Everest and, from there, to [color=red]access[/color] the [color=red]satellite system signals[/color] that would [color=red]allow[/color] them to determine a precise elevation. And it turns out the famous peak[color=red] is actually[/color] a few feet higher than was previously thought.[/font]#^3M~~mh,b5E%u;I

{ [5^&g~-[\t(x [font=Times New Roman]Now, you have been reading articles about the [color=red]tremendous[/color] damage done to life and [b]property[/b] by earthquakes. This is why seismologists have been working so hard to develop [color=red]methods of [/color]earthquake predication. We can now predicate earthquakes fairly well, but predications only [color=red]locate[/color] potential areas [color=red]of[/color] danger. They don’t predicate [color=red]specific [/color]time and location at which[color=red] an [/color]earthquake [color=red]is likely[/color] to occur. Today I want to introduce to you three predication models that have been developed. The first predication model[color=red] looks along [/color]earthquake[color=red] faults[/color], those[color=red] cracks [/color]in earth [color=red]crust[/color], to find what [color=red]are[/color] known as seismic gaps. The seismic gaps are the places where the fault [color=red]has shown little or no seismic activity[/color] for a long time. This theory [color=red]postulates[/color] that [color=red]such places[/color] are due for a major shock. The second model relies on phenomena, like [color=red]ground tilt[/color]. Using long [color=red]cylindrical tubes[/color] containing water, observers[color=red] noted[/color] that ground tilt tend to occur before major earthquakes. That lead them to [color=red]correctly[/color] predicate the big H quake of 1985, the first successful earthquake predication scientists have ever made. A million people were [color=red]evacuated[/color] from that Chinese city before the earthquake [color=red]struck[/color]. Unfortunately, this method [color=red]hasn’t worked[/color] consistently, so we can’t say it’s been perfected. The third model is based on the theory that major earthquakes [color=red]closely [/color]follow [b]a series of[/b] minor ones. Stating with measurements and [color=red]timing[/color] of smaller quakes, [color=red]a complex formula [/color]calculates [color=red]the times of increased possibility of a much large [/color]earthquake. Right now, this method, like the first method, can not predicate specific [color=red]times[/color] and place[color=red]s[/color], but that may change as it is further[color=red] developed[/color]. For the moment, none of these models can predicate with reasonable[color=red] levels[/color] of confidence.[/font]k$c:ks{K;`K

[font=Times New Roman]One [color=red]reason[/color] [b]oceanographers [/b]analyze the [b]sediment [/b]on the ocean floor is to see how long terms changes in earth temperature have affected the depth of the ocean. By analyzing the remains of sea animals in the old layers of ocean sediment, oceanographers can determine the depth of the ocean in the past. They[color=red]’ve analyzed[/color] hundreds of [color=red]such[/color] layers, including some from the coldest periods of the earth history, the ice ages. What they’ve found is that during the ice ages the [color=red]amount of[/color] the water in the ocean [color=red]decreased[/color]. Water levels in the ocean dropped [color=red]by[/color] about four hundred feet. Water from the ocean[b] evaporated[/b] and became[b] frozen[/b] in the [b]continental[/b] [b]glaciers [/b]so it didn’t drain back into the ocean. When temperatures [b]eventually [/b]rose again, the glaciers [b]melted[/b] and the oceans returned to their former depths. Analysis of sedimentary data indicates that the [color=red]periods [/color]of glaciers freezing and melting [b]occurred[/b] [color=red]in regular cycles [/color]of twenty thousand, [b]forty[/b] thousand and one hundred thousand years. Oceanographers are interested in the history of [color=red]the seawater levels [/color]because they hope to use the historical data in order to [b]predict[/b] possible effect that global warming could have on the seawater levels. If [b]industrial[/b] pollutants are capable of [color=red]heating[/color] global temperature[color=red]s[/color] to the point that the glaciers begin to melt, it is [color=red]urgent [/color]for us to know precisely how high seawater will rise as a result.[/font]

[font=Times New Roman]The old [color=red]Canada[/color]
8eW|u\r8vT'{ road is a [color=red]long lost [/color]trail between the [color=red]Canadian province of Quebec and Maine, [/color]in the northeast corner of United States. Yes, it really was lost and finding it again was a complex process that involved[color=red] state of the art technology[/color]. How the location of the road was [b]pinpointed[/b] was very interesting. And I will return to it [color=red]as soon as [/color]I [color=red]have[/color] given you a little background information. The road was [b]begun[/b] in 1817, a few years before Maine even became a state. At the time, Quebec was a major market for [b]livestock[/b], crops and fish, so a road to Quebec was seen by [color=red]officials in Maine[/color] was necessary to trade. For about twenty years, the movement of people and goods was mainly from Maine to Quebec, but then the trend reversed, as thousands of [b]Canadians[/b] [color=red]immigrated[/color] to Maine to escape [color=red]poor crops[/color], a lack of jobs and the thread of disease. I think it was a [color=red]cholera epidemic[/color]. Besides [color=red]these[/color] negative reasons, major building projects in Maine also make the state very attractive for[color=red] the[/color] Canadians who needed work. I should stress, though, immigration during that period went in[color=red] both [/color]directions. In fact, the flow of people and goods went completely [color=red]unhindered[/color]. There was not even a [color=red]border[/color] post until around 1850. People of the time [color=red]saw[/color] Maine and Quebec [color=red]as a single region [/color]mainly because of the [color=red]strong French influence[/color], which is still influenced in Maine today, which is still evident in Maine today. Eventually the road fell into disuse, as[color=red] a [/color]major railway was completed. Finally, people simply forgot about it and that’s how it [color=red]came to be[/color] lost. This brings me back to the original topic.[/font]

G/L6n6F+H O;`?%{ [font=Times New Roman]Scientists are always on the[color=red] lookout[/color] for alternatives source[color=red]s[/color] of energy. Today, we’re going to discuss one that is so plentiful; they say they could [color=red]supply [/color]more energy than all coal and oil in the world. It is [color=red]found in something [/color]called [color=red]gas hydrate[/color], and believe it or not, that is a kind of ice. That is right. But the water in this ice[color=red] was way down[/color] below the earth surface when it [color=red]was [/color]frozen, so it was under a lot of pressure. And trapped[color=red] inside [/color]the crystal [color=red]of [/color]ice are individual molecules of [color=red]methane[/color], that’s what is in natural gas. All [color=red]this [/color]make gas hydrate pretty strange stuff. If you touch a [color=red]match[/color] to a piece of [color=red]this ice[/color], it’ll burst into flame. And when geologists bring [color=red]a chunk of[/color] it up to the surface to study [color=red]at [/color]normal air pressure and temperature, gas hydrate begins to [color=red]hiss and bubble[/color]. And in less than half of an hour the ice melts and the[color=red] methane [/color]inside escapes into the air. Now, as you might guess, this can make gas hydrate [color=red]kind of[/color] hard for[color=red] miners[/color] to handle. And then there is a problem of where if is located, in frozen [color=red]arctic regions [/color]or in the ocean water off the[color=red] Atlantic [/color]coast and up to a mile down. Environmentalists warn that mining it could even be [b]disastrous[/b]. Offshore drilling could [color=red]allow[/color] the seawater to [color=red]seep down[/color] into the huge[color=red] icy deposits[/color] and release [color=red]tons of [/color]methane up into the atmosphere. And methane, the listeners may recall, is a greenhouse gas that could really [b]worsen[/b] the problem of global warming. [color=red]So[/color], gas hydrate may offer some interesting possibilities, but with all these drawbacks, I am not going to [color=red]hold my breath waiting for it to fuel[/color] my furnace.[/font]`c%^2d0y^f1w

/Tm/k Dg#Y [font=Times New Roman]Look at our topographical map. You will see that[color=red] the middle third[/color] of North America continent from [color=red]Rocky Mountains[/color] almost to the [color=red]Mississippi River[/color] is pretty flat. This is the Great Plains. This kind of area is sometimes called [color=red]a[/color] [b]prairie[/b] or sometimes[color=red] a steppe[/color]. That is STEPPE. The defining [b]features[/b] are [color=red]level terrain[/color], dry climate and [color=red]an absence of [/color]trees. The Great Plains are actually the former bed of [color=red]shallow inland sea[/color]. Over millions of years, the sediment left by the glaciers, water and wind [color=red]smoothed out [/color]the dry sea bed. As I said, the Great Plains are [b]bordered[/b] on the west by the Rocky Mountains. And it is really the Rocky Mountain[color=red]s[/color] that [color=red]are[/color] responsible for the formation of the grasslands. The mountains are so high that they block the [color=red]heavy moist air[/color] [color=red]traveling eastward[/color] from the Pacific Ocean. [color=red]Lighter[/color], drier air passes over the mountains. Until people [color=red]intervened with [/color][b]irrigation[/b] and farm, only grass could grow on the dry windy [color=red]plain[/color]. In fact, we could divide the Great Plains into three zones. In the west, where it is driest and windiest, the grass is very short. In the eastern zone, there is more rain and the grass grows [color=red]as high as[/color] three hundred and sixty centimeters. In the [color=red]middle third[/color], there is a [color=red]mix [/color]of grass species that grow to an [b]intermediate[/b] height.[/font]0W0WaslAU

[font=Times New Roman]Since we [color=red]have been[/color] discussing alternative fuels lately, I [color=red]wanted[/color] to pass on [color=red]to you[/color] some information I read bout a new fuel [color=red]that’s been[/color] in the news a lot lately. It is called A21. It is composed of water and a chemical known as [color=red]naphtha[/color]. It seems to be a very promising fuel because it is much cleaner than the gasoline[color=red] that [/color]we use today. That’s not to say it doesn’t pollute, but it is cleaner. A21 isn’t like [color=red]some other[/color] alternative fuels that require [color=red]completely [/color]new types of [b]engines[/b]. A21 still works in regular everyday [b]combustion[/b] engines like the ones in cars with only [b]minor[/b] mechanical [color=red]modifications[/color]. So changing over wouldn’t be a big deal. You may doubt some of the claims[color=red] as[/color] many researchers have. Some people [color=red]feared that[/color] because it contains about forty five percent water it would freeze in [color=red]the[/color] winter. But a small amount of antifreeze was added to it and that seems to [color=red]have solved[/color] the problem. A21 has recently [color=red]undergone street tests[/color] in buses in [color=red]Reno[/color][color=red], Nevada[/color]. So far it seems to work just fine. It is a good thing, especially in Nevada, because the state government there has passed a law requiring [color=red]that[/color] a large [color=red]percentage [/color]of vehicles in Nevada [color=red]run on [/color]alternative fuels. A21 should help.[/font]

Y,dv\+A_ [font=Times New Roman]The winds of[color=red] a tornado[/color] are the most [b]violent [/b]and [b]destructive[/b] ones on earth. Any of you who have seen one know very well how[b] frightening [/b]and powerful they are. What is interesting about[color=red] them [/color]is that scientists don’t [color=red]actually[/color] know exactly why tornadoes occur. We do know, however, what happens when tornadoes are formed. As you remember, a [color=red]front [/color]occurs, when cool dry air from the north meets the warm humid air [color=red]coming [/color]from the south (from the Gulf of Mexico for tornadoes in the United States) [color=red]Where[/color] these air masses meet, a narrow zone of [color=red]storm clouds [/color]develops, and [color=red]thunderstorms[/color],[color=red] and sometimes tornadoes[/color], occur. How is this violent weather produced? Well, a mass of warm, humid air rises very rapidly. As it rises, more warm air rushes into [color=red]replace it[/color]. This [color=red]inrushing[/color] air also rises, and in some cases, especially when there is a[color=red] extreme thermal instability[/color], [color=red]begins[/color] to rotate. When this happens, the rotating air forms a tornado. Even if you[color=red]’ve [/color]seen tornadoes only in movies, you know that [color=red]they[/color] can demolish buildings in seconds. This is possible because when a tornado passes over a house,[color=red] it sucks up the air[/color] from around the house and so the air pressure outside the house drops rapidly. Inside pressure remains the same. So air pressure inside is greater than air pressure outside. The result is that the building[b] explodes [/b]outward. Next, we’ll talk a [color=red]little[/color] bit about how new technological developments are being used to [color=red]try to[/color] predict tornadoes.[/font]

[font=Times New Roman]It seems like [color=red]only[/color] yesterday that I was sitting where you are, just finishing my first year[color=red] of[/color] medical school and wondering if [color=red]I’d ever[/color] get a chance to use all my new knowledge on a real life [b]patient[/b]. Well, I have good news for you. You don’t have to wait until your third or [b]fourth[/b] year [color=red]of [/color]medical school to get some [color=red]hands-on[/color] experience. The [b]dean[/b] has invited me here to tell you about the university’s rural opportunity program. If you [color=red]enroll [/color]in the program, you can have an opportunity this summer, after your first year of medical school to spend four to six weeks observing and assisting a [color=red]real [/color]physician, like me, in a small rural community. You [color=red]won’t [/color]have to compete with other students for time and attention and you can [color=red]see [/color]what life[color=red] as [/color]a country doctor is really like. The program [color=red]was[/color] designed to encourage medical students like [color=red]yourselves[/color] to considerate careers in rural communities [color=red]that are [/color]still [color=red]understaffed[/color]. It seems that medical students are afraid to go [color=red]into[/color] rural family practice for two reasons. First, they don’t know much about it. And second, [color=red]specialists[/color] in the cities usually make more money. But [color=red]on the upside[/color], in rural practice doctors can really get to know their patients and be respected members of the community. I participated in the program when it first started and spent six weeks in a small rural town. Let me tell you it was really great. I got to work with real patients. I watched the birth of a child, assisted [color=red]an accident victim[/color] and had lots of [color=red]really practica[/color]l hands-on experience all in one summer. And to my surprise, I found that country life has [color=red]lots[/color] to offer that city life doesn’t, no pollution or traffic jams for instance. My experience made me want to work where I am needed and appreciated. I don’t miss the city at all.[/font]Cf$v(^(Q |r^ `

[font=Times New Roman]Located at the NASA research center [color=red]in Iowa[/color] is a 5000-gallon[color=red] vat[/color] of water and inside the [b]tank[/b] is an underwater [color=red]treadmill[/color], designed by Dava Newman, an [color=red]aerospace[/color] engineer. For four years, Newman observed [color=red]scuba divers[/color] as they [color=red]stimulated[/color] walking on the moon and[color=red] on[/color] Mars on her underwater [color=red]moving belt[/color]. She wanted to discover how the gravity [color=red]of [/color]the moon and [color=red]of [/color]Mars would affect human movement. To do this, Newman attached weight[color=red]s[/color] to the divers and then [b]lowered[/b] them into the tank [color=red]and [/color]onto the treadmill. These weights were carefully adjusted [color=red]so that [/color]the divers could experience underwater the gravity of the moon and [color=red]of [/color]Mars as they walked on the treadmill. Newman concluded that walking on Mars will probably be easier than walking on the moon. The moon has less gravity than Mars does, so [color=red]at lunar gravity[/color], the divers struggled to keep their balance and walk[color=red]ed [/color]awkwardly. But at [color=red]Martian[/color] gravity, the divers have greater [color=red]traction[/color] and [b]stability[/b] and can easily adjust to a pace of 1.5 miles per hour. As Newman gradually increased the speed of the treadmill, the divers[color=red] took longer graceful strides[/color] until they [color=red]comfortably settled into[/color] a even quicker pace. Newman also noted that at Martian gravity divers [color=red]needed[/color] less oxygen. The data Newman [color=red]collected[/color] will help

in the future design of Martian space suits. Compared to lunar space suits, the Martian space suits will require smaller air tanks. And to allow for[color=red] freer[/color] movement, the [color=red]elbow and knee areas[/color] of the space suits will also be altered.[/font] PvCT(c

[font=Times New Roman]Most people think of [b]astronomers[/b] [color=red]as[/color] people who spend their time in cold [b]observatories[/b] peering through telescopes every night. In fact, a typical astronomer spends most of his or her time [b]analyzing[/b] data and [color=red]may[/color] only be at [color=red]the [/color]telescopes a few weeks of a year. Some researchers work on [color=red]purely [/color]theoretical problems and never use [color=red]a [/color]telescope at all. You may not know how rarely images [color=red]are viewed[/color] directly through telescopes. The most common way to observe the [color=red]skies[/color] is to photograph them. The process is very simple. First a photographic [color=red]plate[/color] is [color=red]coated[/color] with a [color=red]light-sensitive[/color] material. The plate is [color=red]positioned[/color] [color=red]so that[/color] the image received by the telescope is [color=red]recorded [/color]on it. Then the image can be developed, enlarged, and published, so that many people could study it. Because most of the astronomic objects are very remote, the light we receive from them is rather feeble. But by using a telescope as a cinema, long time [color=red]exposures [/color]can be made. In this way, objects can be [color=red]photographed[/color] that are a hundred times [color=red]too faint to be seen [/color]by just looking [color=red]through[/color] a telescope.[/font][Z$ejN-LWs

J7{I\Y0G:\ [font=Times New Roman]Thank you. It’s great to see so many of you interested in the series on [b]Survival [/b]in outer space. Please excuse the cameras. We are being [color=red]videotaped[/color] for the local TV stations. Tonight I [color=red]am going [/color]to talk about the [color=red]most [/color]basic aspect of survival- the space suit. When most of you imagine an [b]astronaut[/b], that’s probably the first thing [color=red]that[/color] comes to mind, right? Well, without space [color=red]suits[/color], it will not be possible for us to survive in space. For example, outer space is [color=red]a vacuum[/color]. There is no gravity or air pressure. Without protection, [color=red]a body [/color]would [color=red]explode[/color]. What is more, we[color=red]’d[/color] cook in the sun [color=red]or [/color]freeze in the[color=red] shade [/color]with the temperatures ranging from a[color=red] toasty[/color] three hundred degrees above to a cool three hundred degrees below zero [color=red]Fahrenheit[/color]. The space suit that NASA [color=red]has [/color]developed is truly a [color=red]marvel[/color]. The photo [color=red]enlargement here [/color]is a l[color=red]ife-size[/color] image of [color=red]an [/color]actual space suit [b]worn[/b] by astronauts[color=red] on the last space shuttle mission[/color]. This part is the [color=red]torso[/color]. It is made of seven extremely [b]durable[/b] layers. This [color=red]thick insulation[/color] protects against temperature extremes and radiation. Next is what they call a[color=red] bladder[/color] of oxygen. This [color=red]inflatable [/color][b]sac [/b]filled with oxygen to stimulate [color=red]atmospheric[/color] pressure. This [color=red]bladder[/color] [color=red]presses[/color] against the body with the same force as the [color=red]earth’s[/color] atmosphere at the sea level. The[b] innermost[/b] layers provide liquid cooling and[color=red] ventilation[/color]. Despite all the layers, the suit is flexible, allowing free movement so we can work. Another really sophisticated part of the space suit is the helmet. I brought one along to show you. Can I have a volunteer come and demonstrate?[/font]4l'z#} s3p II

[font=Times New Roman]I am sure you realize that your research paper[color=red]s[/color] are due in six weeks. I have looked at your [b]proposed[/b] topics and made commits about them. The most frequent problem was proposing too broad a topic. Remember it is only a fifty-page paper. As I return your topic papers, I’d like to look over the schedule which [color=red]sketches out[/color] what we’ll do during the next two weeks. Today is Monday, by Friday I want your preliminary outline. Please be sure to [b]incorporate [/b]the suggestions I have made on your topics in your outlines. Next week, I will have a conference with each of you. I’ve [color=red]posted[/color] a schedule on my office door. Sign your name to indicate time you are [b]available[/b] to for an appointment. In the conference, we’ll discuss your preliminary outline. Then you can make the necessary [color=red]revisions[/color] and hand in your final outline which is due in two weeks from today. Use the outline style in your textbook and remember it should be no more than two-page long. Be sure to begin with the thesis statement that is [color=red]with [/color]a precise statement of the point you intend to [color=red]prove [/color]and include a conclusion. Have you got all that? Your two-page preliminary outlines are due at the end of this week and [color=red]the [/color]final outlines are due after your conference. Follow the textbook style and include a thesis statement and a conclusion.[/font]"a[yg9G4wP2CW7^

mocWL,BXjP0g)N [font=Times New Roman]We have probably all wondered how a new word gets into the dictionary. Take the word ”doofus” for example, [color=red]spelled [/color]DOOFUS, meaning a stupid or [color=red]incompetent [/color]person. This word, [color=red]which [/color]has been around since the late 1960s[color=red] in a slang sense[/color], made it into the [color=red]Merriam-Webster’s Collegiate Dictionary[/color] only in 1993. Why did it take so long? Well, first of all, dictionary editors [color=red]like[/color] to wait, at least three years, to be sure the word is going to last, especially a [color=red]slang [/color]word. They don’t want to put in a word [color=red]prematurely[/color] and then have to [color=red]take[/color] it out in the next edition. But even for words that [color=red]are not slang[/color], getting into the dictionary isn’t easy. New words have to pass a lot of [color=red]editorial[/color] tests including how [b]difficult[/b] or easy they are to look up. There is also a limit to how thick [color=red]a[/color] dictionary can be and how small[color=red] its [/color]type can get [color=red]before people feel [/color]they don’t want to use it. Some words have to be taken out before[color=red] others[/color] can go in. Collegiate dictionary add about ten thousand new words to every edition and [color=red]it[/color] takes out only a few hundred, so choices have to be made very carefully.[/font]

[font=Times New Roman]You[color=red]’ll[/color] recall[color=red] that in [/color]the last week’s class I [color=red]talked about[/color] the sounds made by[color=red] most [/color]animals, though sometimes complex, are different from human language. Only in humans, [color=red]do these sounds[/color] represent objects and events. Keep in mind that most animals can only repeat their limited [color=red]utterances[/color] over and over again, [color=red]while[/color] humans can say [color=red]things[/color] that have never [color=red]been[/color] said before. Today I want to focus on human language and how it developed. I [b]doubt[/b] that you’ll be [b]surprised [/b]when I say that evolution of language [color=red]was[/color] slow and[color=red] laborious[/color]. There[color=red] is [/color]some reliable [color=red]evidence [/color]that language began with early humans a million and a half years ago. Through the study of the size and shape of[color=red] brain fossils[/color], scientists [color=red]have [/color]determined that early human brains, like modern brains, have [color=red]a[/color] left hemisphere [color=red]slightly larger[/color] than the right hemisphere. We know that, in modern [color=red]humans[/color], the left hemisphere is the [color=red]seat [/color]of the language. And we also know that the early human brains have [color=red]a [/color]well-developed [color=red]frontal section[/color], know as [color=red]Broca’s area[/color], which[color=red] coordinates[/color] the [color=red]muscles [/color]of the [color=red]mouth and throat[/color]. It is clear, [color=red]then[/color], early humans [color=red]had[/color] speech [color=red]apparatus[/color]. They can produce any sound that we can. What we don’t know is whether early humans used what they had. Since scholars know [color=red]virtually[/color] nothing about the [color=red]prehistoric[/color] speech [color=red]patterns,[/color] all they can do is to [b]speculate[/b] [color=red]about [/color]how the language [color=red]actually [/color]originated. Let me give you a [color=red]brief summary [/color]of some of [color=red]these theories[/color].[/font]
