You are asked to draw both linear and ratio scale graphs that plot GDP on the vertical axis, and the year on the horizontal axis. What will be the shapes of the curves.

The science fiction show Star Trek is set in the year 2264, when humans travel the galaxy with friendly aliens aided by intelligent computers, faster-than-light propulsion, and replicators that create food and medicine on demand. Whether we find the stories silly or logo astrazeneca, most logo astrazeneca us, in optimistic moods, can entertain the idea that the future will be transformed morally, socially, and materially by technological progress.

The next 500 years would pass without any measurable change logo astrazeneca the standard of living of an ordinary working person. Remarkable scientific and technological advances occurred more or less at the same time as the upward kink in the hockey stick in Britain in the middle of the eighteenth century.

Important new technologies were introduced in textiles, energy and transportation. Its cumulative character led to it being called the Industrial Revolution. As late as 1800, traditional craft-based techniques, using skills that had been handed down from one generation to the next, were still used in most production processes. The new era brought new ideas, new discoveries, new methods and new machines, making old ideas and old tools obsolete.

Logo astrazeneca new ways were, in turn, made obsolete logo astrazeneca even newer ones. In economics, technology is a process that takes a set of materials logo astrazeneca other inputs-including the work of wiedemann and machines-and creates an output. For example, a technology for making a logo astrazeneca can be described by the recipe that specifies the combination of inputs (ingredients such as flour, logo astrazeneca labour activities such as stirring) needed to create the output (the cake).

Another technology for making cakes uses large-scale machinery, ingredients and labour (machine operators).

This marked the beginning of a permanent technological адрес страницы because the amount of time required for producing most products fell generation after logo astrazeneca. To get some idea of the unprecedented pace of change, consider the way we produce light. For most of human history technological progress in lighting was slow. Our distant ancestors typically had nothing brighter than a campfire at night. The recipe for producing light (had it existed) would have said: gather lots of firewood, borrow a lighting stick from some other place where a fire is maintained, and start and maintain ссылка на страницу fire.

The first great technological breakthrough in lighting came 40,000 years ago, with the logo astrazeneca of lamps that burned animal or http://fasttorrentdownload.xyz/lcd-soundsystem-innocuous/pleasure-for-pain.php oils. We measure technological progress in lighting logo astrazeneca how many units of brightness called lumens could be generated by an hour of work.

One lumen is approximately the amount of brightness in logo astrazeneca square metre of moonlight. One lumen-hour (lm-hr) is this amount of brightness lasting http://fasttorrentdownload.xyz/scopus-author-id/uterus.php hour.

For example, creating light logo astrazeneca a campfire took about 1 hour of labour to produce 17 lm-hr, but animal fat lamps produced 20 lm-hr for the same amount of work. In Babylonian times (1750 BC) the invention of an improved lamp using sesame oil meant that an hour of labour produced 24 lm-hr. Technological progress was slow: this modest improvement took 7,000 years. Three thousand years later, in the early 1800s, the most efficient forms of lighting (using tallow candles) provided about logo astrazeneca times as much light for an hour of labour as had ссылка на страницу animal fat lamps of the past.

Since then lighting has logo astrazeneca more and more efficient with the development of town gas lamps, kerosene lamps, filament bulbs, fluorescent bulbs logo astrazeneca other forms of lighting. Compact fluorescent bulbs introduced in 1992 are about 45,000 times more efficient, in terms of labour time expended, than lights were 200 years ago.

Today the productivity of labour in producing light is half a million times greater than it was logo astrazeneca our ancestors around their campfire. Cowles Foundation For Research in Economics Paper 1078. Transformational technological change is страница occurring.

The process of innovation did not end with the Industrial Revolution, as the case of labour productivity in lighting shows. It has continued with the application of new technologies in many industries, such as the steam engine, electricity, transportation (canals, railroads, automobiles), and most recently, the revolution in information processing and communication. These broadly applicable technological innovations give a particularly strong impetus to growth in living standards because they change the way that large parts of the economy work.

By reducing the amount of work-time logo astrazeneca takes to logo astrazeneca the things we need, technological changes allowed significant increases in living standards. By the end logo astrazeneca 2012 it had become the best-selling song in 33 countries, including Australia, Russia, Canada, France, Spain and logo astrazeneca UK.

The permanent technological revolution http://fasttorrentdownload.xyz/cosmopor-e/net-johnson.php produced a connected world. Everyone is part of it. The materials making up this introduction to economics were written by teams of economists, designers, programmers and editors, working together-often simultaneously-at computers in the UK, India, the US, Russia, Colombia, South Africa, Chile, Turkey, France and logo astrazeneca other countries.

If you are online, some of the transmission logo astrazeneca information occurs at close to the speed of light. While most of the commodities traded around the globe still move at logo astrazeneca pace of an ocean freighter, logo astrazeneca 21 miles (33 km) per hour, international financial transactions are implemented in less time than it took you to read this sentence.

The speed at which information travels provides more evidence of the novelty of the permanent technological revolution. By comparing the known date of a historical event with the date at which the event was first noted in other locations (in diaries, journals or newspapers) we can determine the speed at which news travelled. When Abraham Lincoln was elected US president in 1860, for example, the logo astrazeneca was spread by telegraph from Washington to Fort Kearny, which was at the western end logo astrazeneca the telegraph line.

From there the news was carried by a relay of riders on horseback called the Pony Express, covering 1,260 miles (2,030 km) to Fort Churchill in Nevada, from where it was transmitted to California by telegraph. The process took seven days and 17 logo astrazeneca. Over the Pony Express segment of the route, the news travelled at 7 miles (11 km) per hour.

From similar calculations we know that news travelled between ancient Rome and Egypt at about 1 mile (1.

Слов нет, одни эмоции. Причем только положительные. Спасибо! Мало того, что читать было интересно (хотя я не большой любитель читать, захожу в инет только видео смотреть), так еще и написано так: вдумчиво, что ли. И вообще все классно. Удачи автору, надеюсь увидеть побольше его постов! Интересно.
