    Following the terminology of political economist Joseph Schumpeter, an invention differs from an innovation. While an invention is merely theoretical (even though the legal protection of a patent may have been sought), an innovation is an invention that has been put into practice. However, these conflicts with the theory of social anthropologists and other social sciences researchers. In social sciences, an innovation is anything new to a culture. The innovation does not need to have been adopted. The theory for adoption (or non-adoption) of an innovation is called diffusion of innovations. This theory, first put forth by Everett Rogers, considers the likelihood that an innovation will ever be adopted and the taxonomy of persons likely to adopt it or spur its adoption. Gabriel Tarde also dealt with the adoption of innovations in his Laws of Imitation.[citation needed]

    几周前,罗老师叫我和其它4个同学去听小发明课。听了以后,我深受启发,马上制作了多功能饭盒和环保清洁书写擦。

      首先,我把目光瞄准了饭盒。可左思右想也没有想到饭盒有什么不方便的,“啊,终于想起来了。”我自言自语地说,“能否加一个工俱箱呢?”晚上我就开始了我的“秘密行动”,趁爸爸妈妈没发现,我便拿起剪刀、胶布悄悄地溜进我的“实验室”——厨房,把准备好的饭盒、筷子、勺子整齐地放在一起,拿起胶带一贴,好,我的多功能饭盒大功告成。第二天,老师拿着我的多功能饭盒对我说:“你这个发明实用性很高,但上面的胶布用过几次粘性就不强了,要在上面加个盖子。”我拿着我的发明回家后,迅速找了个盖子装在饭盒上。我到校后再把它交给了老师,我的这个发明也就勉强成功了。

      之后,我又准备发明一个新的东西。“嘿,异想天开节目不是经常播放黑扳擦的发明吗,我也要发明,而且跟别人的不一般”,想到这里,我找来一块长15厘米、宽5厘米的长条形泡沫,在泡沫正面用小刀锉了一个洞,再将粉笔安装上去,就可以握着泡沫写字了,同时还可以用泡沫的下端擦拭,真是一举多用,但就是擦拭的效果还比不上学校的擦子。爸爸下班后,带回来黑板擦,我割下擦子的一部分,用布贴胶安在泡沫的下端,可就是贴不稳,怎么办呢?我突然想出一个好办法,在擦子四周用胶围上二圈就能固定了。“好了,完成了。擦拭不理想的问题也解决了。”连爸爸也说我这个发明比上一次好,可不是吗,我这个发明费尽了三天两夜才做出来的,能不好吗。它既能书写不脏手,又能很方便地擦拭。我恨不得马上把这个发明交给老师。时间过得可真慢,总算等到第二天早上,二节课下课,我怀着喜悦的心情把发明交给老师,老师告诉我,如果把一个小缺点改了,也许能获奖。当时,我一听,差点一蹦三尺高,喊出声来“我成功了。”这是我第一次做小发明,没想成功了。

      这次发明使我品尝了“先苦后甜”的快乐,也明白了这样一个道理:如不经过细心的观察、认真的思索和反复的实验,又怎能获得艰辛之后的笑容呢?

    The abacus was invented in the sixth century by Chinese people.The umbrella was invented about 4000 years ago in Assyria,China and Egypt.The binoculars was invented in 1854 by Ignatio Porro in Italy.The camera was invented in 1827 by Joseph Nicephore Niepce who took the first picture.The bicycle was invented in 1880s in England.

    Computer enjoys a long history and it is one of the most inventions.

    Today, it is widely used in many fields.

    The oldest computers is the abacus used in China several centries ago, but the computer is becoming smaller and smaller now, and it can be used in shops, factories and hospitals.

    The computers are developing with an astonishing speed, and no one could expect what it will be like in the future.

    1.The computer has a long history , it is one of the most important nventions. Today, the computer applies in many ways.
    2.The oldest computer is was the abaci which worked in many A.Ds ago in China, but now the couputer is getting smaller and smaller, and it can do many works, it can work in shops,factories and hospitals and other places.
    3.The computer grows very fast, nobody can know the future of it.

    An invention is an object, process, or technique which displays an element of novelty. An invention may sometimes be based on earlier developments, collaborations or ideas, and the process of invention requires at least the awareness that an existing concept or method can be modified or transformed into an invention. However, some inventions also represent a radical breakthrough in science or technology which extends the boundaries of human knowledge. Legal protection can sometimes be granted to an invention by way of a patent.

    [edit] The process of invention

    Over time, humanity invented objects and methods for accomplishing tasks which fulfill some purpose in a new or different manner, usually with the objective of realizing that purpose in a faster, more efficient, easier or cheaper way.

    [edit] Ideas as a starting point

    Although a new or useful object or method may be developed to fulfill a specific purpose, the original idea may never be fully realised as a working invention, perhaps because the concept is in some way unrealistic or impractical.

    A "castle in the air" or a "pie in the sky" (or "castles in Spain") may refer to a creative idea which does not reach fruition due to practical considerations. The history of invention is full of such castles, because inventions are not necessarily invented in the order that is most useful; for example, the design of the parachute was worked out before the invention of powered flight. Other inventions simply solve problems for which there is no economic incentive to provide a solution.

    On the other hand, any barriers to implementation may simply be an issue of engineering or technology which can be overcome in time with scientific advances. History is also replete with examples of ideas which have taken some time to reach physical reality, as demonstrated by various ideas originally attributed to Leonardo da Vinci which are now expressed in everyday physical form.

    [edit] Commercialization

    Inventors may be inspired to invent through a desire to create something new or better, simple altruism, or for competitive or commercial reasons. An invention may also result from a combination of these motivating factors. Although many inventors may have in mind the commercialization of their product, very few will secure the funding and support often needed to develop and launch a product in the marketplace, and fewer still will experience lasting commercial success or the economic reward they may have expected. However, inventor associations and clubs and business incubators can be used to provide the mentoring, commercial skills and economic resources which private inventors may often lack. Entrepreneurship and an awareness of the demands of a changing marketplace are typical characteristics of successful inventors.

    Most great inventors developed countless prototypes, changing their designs innumerable times. Today much emphasis is placed on research and development, prototyping and finding solutions.

    Inventions are one of the chief examples of "positive externalities" (an economist's name for a beneficial side-effect that falls on those outside a transaction or activity). One of the central concepts of economics is that externalities should be internalized: unless some of the benefits of this positive externality can be captured by the parties, the parties will be under-rewarded for their inventions, and systematic under-rewarding will lead to under investment in activities that lead to inventions. One important economic effect of the patent system is to capture those positive externalities for the inventor (or the party that hired the inventor), so that the economy as a whole will invest a more-closely-optimum amount of resources in the process of invention.
