. Since the speed of light is well known, any delay in receiving the satellite39。 s signal can be converted into a distance. 9 In Japan there are already over a million cars with some type of navigational capability. (Some of them locate a car39。 s position by correlating the rotations in the steering wheel to its position on a map.) 10 With the price of microchips dropping so drastically, future applications of GPS are virtually limitless. The mercial industry is poised to explode, says Randy Hoffman of Magellan Systems Corp. , which manufactures navigational systems. Blind individuals could use GPS sensors in walking sticks, airplanes could land by remote control, hikers will be able to locate their position in the woods the list of potential uses is endless. 11 GPS is actually but part of a larger movement, called telematics, which will eventually attempt to put smart cars on smart highways. Prototypes of such highways already exist in Europe, and experiments are being made in California to mount puter chips, sensors, and radio transmitters on highways to alert cars to traffic jams and obstructions. 12 On an eightmile stretch of Interstate 15 ten miles north of San Diego, traffic engineers are installing an MITdesigned system which will introduce the automated driver. The plan calls for puters, aided by thousands of threeinch magic spikes buried in the highway, to take plete control of the driving of cars on heavily trafficked roads. Cars will be bunched into groups of ten to twelve vehicles, only six feet apart, traveling in unison, and controlled by puter. 13 Promoters of this puterized highway have great hopes for its future. By 2020, telematics may well be incorporated into one of the major highways in the United States. If successful, by 2020, as the price of microchips drops to below a penny a piece, telematics could be adopted in thousands of miles of highways in the United States. This could prove to be an environmental boon as well, saving fuel, reducing traffic jams, decreasing air pollution, and serving as an alternative to highway expansion. UNIT 3 Harvey Mackay, who runs his own pany, often interviews applicants for jobs. Here he lets us into the secret of what qualities an employer is looking for, and gives four tips on what can help you to stand out from the crowd. Get the Job You Want Harvey B. Mackay 1 I run a manufacturing pany with about 350 employees, and I often do the interviewing and hiring myself. I like talking to potential salespeople, because they39。 re our link to customers. 2 When a recent college graduate came into my office not too long ago looking for a sales job, I asked him what he had done to prepare for the interview. He said he39。 d read something about us somewhere. 3 Had he called anyone at Mackay Envelope Corporation to find out more about us? No. Had he called our suppliers? Our customers? No. 4 Had he checked with his university to see if there were any graduates working at Mackay whom he could interview? Had he asked any friends to grill him in a mock interview? Did he go to the library to find newspaper clippings on us? 5 Did he write a letter beforehand to tell us about himself, what he was doing to prepare for the interview and why he39。 d be right for the job? Was he planning to follow up the interview with another letter indicating his eagerness to join us? Would the letter be in our hands within 24 hours of the meeting, possibly even handdelivered? 6 The answer to every question was the same: no. That left me with only one other question: How well prepared would this person be if he were to call on a prospective customer for us? I already knew the answer. 7 As I see it, there are four keys to getting hired: 8 1. Prepare to win. If you miss one day of practice, you notice the difference, the saying goes among musicians. If you miss two days of practice, the critics notice the difference. If you miss three days of practice, the audience notices the difference. 9 When we watch a worldclass musician or a top athlete, we don39。 t see the years of preparation that enabled him or her to bee great. The Michael Jordans of the world have talent, yes, but they39。 re also the first ones on and the last ones off the basketball court. The same preparation applies in every form of human endeavor. If you want the job, you have to prepare to win it. 10 When I graduated from college, the odds were good that I would have the same job for the rest of my life. And that39。 s how it worked out. But getting hired is no longer a onceinalifetime experience. Employment experts believe that today39。 s graduates could face as many as ten job changes during their careers. 11 That may sound like a lot of pressure. But if you39。 re prepared, the pressure is on the other folks the ones who haven39。 t done their homework. 12 You won39。 t get every job you go after. The best salespeople don39。 t close every sale. Michael Jordan makes barely half of his fieldgoal attempts. But it takes no longer to prepare well for one interview than to wander in halfprepared for five. And your prospects for success will be many times better. 13 2. Never stop learning. Recently I played a doubles tennis match paired with a 90yearold. I wondered how things would work out。 I shouldn39。 t have. We hammered our opponents 61, 61! 14 As we were switching sides to play a third set, he said to me, Do you mind if I play the backhand court? I always like to work on my weaknesses. What a fantastic example of a person who has never stopped learning. Incidentally, we won the third set 61. 15 As we walked off the court, my 90yearold partner chuckled and said, I thought you39。 d like to know about my numberone ranking in doubles in the United States in my age bracket, 85 and up! He wasn39。 t thinking 90。 he wasn39。 t even thinking 85. He was thinki。
