A lot of people think that cultural anthropology is just about studying the special and strange aspects of a society, but anthropologists are also interested in the aspects of life that seems so ordinary that the people in the society think they're not significant. Let me give you an example, I see lots of T-shirts here in class today, but you probably don't think of them as an important part of your culture, but anthropologists could learn a lot about the culture of the US just by studying the T shirt. For one thing, T shirts are a mark of how casual clothing has become in America. No one was quite sure where they came from, but the T shirt first become popular in this country as an under shirt for sellers in the 1940s. Then in the 1950s, it became a sign of rebellion for teenagers to wear this white under shirt by itself, not under anything. By the 1960s and 70s, T shirts have become accepted a spart of the uniform views. You could even say that they came symbolized that generation's attitude towards informality and all thing, including dress. On another aspect that anthropologists would find interesting is that T shirts are used to express personal opinions. Look around this room, you know who likes watch TV show, who went where on vacation, who belongs to what organizations on campus. All of these aspects of our culture are printed on your T shirts. OK, I want to stop for a minute and ask you to try to write down five different conclusions you could reach about American culture from just the T shirts in this classroom.

Finally there is one more element to business success that we haven't talked about, l know what you think I'm going to say, luck and you're partially right. Good entrepreneurs know how to make their own luck and that means being in the right place at the right time with the right product. Let me give you a little example, early in this century, if you're a traveler by train and subway and you happen to get a little thirsty in the station, where would you go for some water? There were no big soda machine at every corner or even drinking fountains, yet there were thousands of thirsty travelers out there, well, what they did was drank water out of one little tin cup that was passed from one thirsty commuter to the next. That's right, everybody drank out of the same cup, and you can bat it didn't get washed after every user. Will, that was the right time for the right product and there was a man who had it. His name is H M and his product was the disposable paper cup. He came up with it just as the nation was becoming concerned about their health risks associated with the tin cups. Laws were passed outlying the things; reports were published showing just what sorts of germs can be passed around from sharing them. Mr. M road that way to become the best known producers of one of the most successful paper products of all time. He originally called his product health cups, but later changed the nature, so can anyone guess what that name might be?

A number of insects rely on leaping or jumping as a way of escaping from enemies. Grosshoppers probably have the most remarkable jumping ability of all these insects. If we think of it in human terms, a grosshopper's high jump is like a human jumping over a five story building. Imagine that a person jumping over a five story building. Well, we'll take a look at the structure of grosshopper's leg to see why it's able to jump so well, but first I wanna talk about the sensory organ that tells grosshoppers
when to jump in the first place. En, OK, a grosshopper has two sensory organs located
at the end of its abdomen. Whenever these organs sense of change in air pressure which might be p
roduced by an enemy approaching, and impulses transmitted to the legs, this first impulse deactivates the nerves that control normal working and sets the grasshopper's jumping muscles into a sort of pre-jumping position. Now at this point, if the sensory organs don't detect additional air pressure changes, the jumping muscles relax and a grosshopper goes back to its normal walking, but if the organs continue to send danger, another set of impulses put the jumping muscles in motion. The distance of the jumping is determined by just how many impulses are transmitted in the second set, the more impulse the longer the jump. OK now let's see why the grosshopper can jump so far . Open your books at the part of that muscle structure of the grasshopper's leg. I think it's in chapter 9.
