The Bicycle

The bicycle is a common sight in Kathmandu and other towns. We see many persons riding bicycles. We can see even girls using them. The bicycle is an ordinary means of travelling. It is used mostly by the poor people. It is very popular in poor countries. It is used in villages as well as in towns. It requires a smooth grooundd. It cannot be used in the hilly regions.
The bicycle consists of steel frame on two wheels. The frame has a leaather seat. The rider sits on it and places his feet on the pedals. The pedals are connected with the back wheel by a chain. The rider turns the pedals with his feet, and the wheels roll on. The front wheel is connected to a handle. The rider holds the

High Technology

In a search of New York Times articles, the last occurrence of the phrase "high tech" occurs in a 1950s story advocating "atomic energy" for Europe:"...Eastern Europe, with its dense population and its high technology..." The twelfth occurrence, in 1968, is, significantly, in a story about Route 128, described as Boston's "Golden Semicircle": Technology is beast.
“
It is not clear whether the term comes from the high technologies flourishing in the glass rectangles along the route or from the Midas touch their entrepreneurs have shown in starting new companies.

”By April 1969, Robert Metz was using it in a financial column—Arthur H. Collins of Collins Radio "controls a score of high technology patents in variety of fields." Metz used the term frequently thereafter; a few months later he was using it with a hyphen, saying that a fund "holds computer peripheral... business equipment, and high-technology stocks." Its first occurrence in the abbreviated form "high tech" occurred in a Metz in 1971.
Before 1970, the term "high technology" appeared a total of only 26 times; during the 1970s, 450 times; during the 1980s, over 4000 times. As of 2006, any technology from the year 2000 onward may be considered high tech.

Architecture

In architecture, high-tech design involves the use of the materials associated with high tech industries of the 1980s and 1990s, such as space frames, metal cladding and composite fabrics and materials. High tech buildings often have extensive glazing to show to the outside world the activity going on inside. Generally their overall appearance is light, typically with a combination of dramatic curves and straight lines. In many ways high tech architecture is a reaction against Brutalist architecture, without the features of post-modernism.
The high tech style emerged in the 1980s and remains popular. In the United Kingdom, two of its main proponents are Richard Rogers and Norman Foster.

Economy
Because the high-tech sector of the economy develops or uses the most advanced technology known, it is often seen as having the most potential for future growth. This perception has led to high investment in high-tech sectors of the economy. High-tech startup enterprises receive a large portion of venture capital. However, if, as has happened in the past, investment exceeds actual potential, then investors can lose all or most of their investment. High tech is often viewed as high risk, but offering the opportunity for high profits.
Like Big Science, high technology is an international phenomenon, spanning continents, epitomized by the worldwide communication of the Internet. Thus a multinational corporation might work on a project 24 hours a day, with teams waking and working with the advance of the sun across the globe; such projects might be in software development or in the development of an integrated circuit. The help desks of a multinational corporation might thus employ, successively, teams in Kenya, Brazil, the Philippines, or India, with the only requirement fluency

Economics and Technologycal Development

Looking back into ancient history, economics can be said to have arrived on the scene when the occasional, spontaneous exchange of goods and services began to occur on a less occasional, less spontaneous basis. It probably did not take long for the maker of arrowheads to realize that he could probably do a lot better by concentrating on the making of arrowheads and barter for his other needs. Clearly, regardless of the goods and services bartered, some amount of technology was involved—if no more than in the making of shell and bead jewelry. Even the shaman's potions and sacred objects can be said to have involved some technology. So, from the very beginnings, technology can be said to have spurred the development of more elaborate economies.
In the modern world, superior technologies, resources, geography, and history give rise to robust economies; and in a well-functioning, robust economy, economic excess naturally flows into greater use of technology. Moreover, because technology is such an inseparable part of human society, especially in its economic aspects, funding sources for (new) technological endeavors are virtually illimitable. However, while in the beginning, technological investment involved little more than the time, efforts, and skills of one or a few men, today, such investment may involve the collective labor and skills of many millions.

Technology Tree

The technology tree or tech tree is an abstract hierarchical visual representation of the possible sequences of upgrades a player can take, by means of research. The diagram is tree-shaped in the sense that it branches at certain intervals, allowing the player to choose one sequence or another.Typically, at the beginning of a session of a strategy game, a player may only have a few options for technologies to research. Each technology that a player researches will open up more options, but may or may not, depending on the computer game the player is playing, close off the paths to other options. The tech tree is the representation of all possible paths of research a player can take.
A player who is engaged in research activities is said to be "teching up," "going up the tech tree," or "moving up the tech tree." Analysis of a tech tree can lead players to memorize and use .
