Vocabulary - Technology • Look at the vocabulary. Translate the words. Which of these things do you use? When do we use these things?
Inventions that changed the world There can be no doubt that the twentieth century is one of the most remarkable in human history for its previously unparalleled rate of technological advances and scientific discoveries, a rate that continues to this day. In fact, there were so many new gadgets invented and discoveries made in the last century that it’s difficult to pare the list down to just the five. So hereisthe list ofsomeofthe most importantones.
The Personal Computer It’s difficult to imagine our world today without computers. Of course, they have been around since World War Two, but they were clunky, massively expensive things that had all the calculating power of a brick. When Steve Wozniak and Stephen Jobs introduced the Apple in 1976, however, it changed everything and the rest is, as they say, history. Today, of course, they are everywhere and we have become so dependent upon them that many people almost feel naked without one. For some, they even provide the very means of maintaining a livelihood: we use them to keep track of our finances, write books, design logos and sell real estate. Plus, they are rapidly replacing the stereo and television in their ability to entertain us with music, movies, and games. (Image: the Apple 1, 1976.)
The Airplane Just as the locomotive made the world a smaller place in the19th century airplane did the same for us in the twentieth century, shrinking our planet to the point that a person could fly anywhere in the world in a matter of hours. Not only have they made travel quick and safe, but aircraft provide many other services as well: from crop dusting and fighting forest fires to overnight delivery of packages and chasing hurricanes. that the way wars are fought has completely changed by them.
Television Yes, I know it destroys brain cells and renders people emotionally and psychologically damaged, but really, where would we be without the boob tube? It is society’s baby-sitter, news source, teacher, entertainer, and story-teller. When in competent hands, television can even be useful at times. Itis the single greatest reason that families no longer eat in the kitchen or dining room anymore, but instead huddle in the living room around their TV on the sofa. Still, even while we pretend we hate it, we can’t help but seeing what’s on tonight. Worse, most of us would have no idea what to do with our time without it, which is probably the saddest commentary of all.
The Internet The computer rendered the typewriter obsolete and made writing in long-hand a thing of the past, but it took the internet to truly turn the computer into the monster it is today. While the airplane shrank our planet to the point that one could fly from New York to London in six hours, the internet made it possible to be there in a few seconds. It also gives anyone the ability to buy and sell almost anything imaginable, find and torment old school mates, watch the latest you-tube videos, and even find their perfect life partner, all for a few bucks a month. Where would we be without it?
Radio Few people today can appreciate the impact the advent of radio had on the twentieth century. Not only did it suddenly make it possible for a person to be heard from hundreds or even thousands of miles away without the use of a wire but it was the center of family life through the end of the Second World War and into the doldrums of the fifties, when it was gradually replaced by the television. Today, it seems to only be useful in the car as a means of keeping the driver from falling asleep behind the wheel or as a tool of talk radio designed to rile the masses
Inventions of the future • What will be the main inventions of the future? What technology will we use in the following areas: • House and living • School and education • Transport • Medicine
Miniaturized Medical Equipment Truly tiny implants that can test, diagnose, and even alert doctors to problems with their patients will replace costly routine visits. Researchers in the Netherlands say they've developed a pill that can be loaded with medicine and programmed to travel to a specific part of the body to unload it. A pen-size device is being developed at the University of Texas that can detect skin cancer without the need for a biopsy.
3D Printing It has been around for a while, but 3D printing is becoming more affordable, which in itself will unleash a host of new inventions and applications, pushing beyond prototypes and models. Scientists have been experimenting using the technology to reconstruct human tissue.
Body Power Researchers are coming up with ways to rechannel the body's natural energies to power electrical devices. Scientists at the Energy Dept.'s Berkeley Lab announced breakthroughs in silicon nano-wire based converters that could let someone charge a cell phone with body heat or charge an iPod through walking.
