He outlines a version of information science as a key discipline within the practice of scientific and technical knowledge domains. His view encompasses the problems of information overload and the need to devise efficient mechanisms to control and channel information for use. — johnston and Webber 4 Indeed, bush was very concerned with information overload inhibiting the research efforts of scientists. His scientist, operating under conditions of "information explosion" and requiring respite from the tide of scientific documents could be construed as a nascent image of the "Information Literate person" in an information saturated society. There is a growing mountain of research. But there is increased evidence that we are being bogged down today as specialization extends. The investigator is staggered by the findings and conclusions of thousands of other workers. — vannevar Bush 3 Schools, colleges, health care, government, etc., are all implicated in the distribution and use of information, under similar conditions of "information explosion" as Bush's post-war scientists. All these people arguably need some sort of personal "information control" in order to function. — bill Johnston, Sheila webber 4 see also edit references edit External links edit.

It is also possible to pass items to another memex. Section 8: The trails made can be shared with others and can also be published, like an encyclopedia (many more new forms are plan to appear). Soon we will be able to establish some kind of direct connection with absorbing material of the record with one of our senses, tactilely, orally, and visually. It would be great for humans to be able analyze present issues. As of now, science has been applied to live better, as well as for destruction. Possibly we may be able to apply the record to become wiser. Critical opinion edit "As we may think" has turned out to be a visionary and influential essay. In their introduction to a paper discussing information literacy as a discipline, johnston and Webber write bush's paper might be regarded as describing a microcosm of the information society, with the boundaries tightly drawn by the interests and experiences of a major scientist of the. Bush provides a core vision of the importance of information to industrial/scientific society, using the image of an "information explosion" arising from the unprecedented demands on scientific production and technological application of World War.
Thus, father's improving the permanence and clarity of the items stored. The memex is a device that could store information and communication (large memory). Some things that can be entered are, newspaper and books. The user is also able to find a particular book as he or she taps on its code on the keyboard. The codes that are frequently used to call forth pages are mnemonic and its possible to browse these pages at different speeds. Section 7: The main feature of the memex is the ability to tie two things together at will. In other words, to be able to associate two arbitrary items when wanted. The user is also able to build a trail, in which they name it, insert a name into the code book, and then taps it out on the keyboard. At any time, the user is able to view two items at the same time, parallel viewing.
Section 5: A machine could be used anywhere where there is logical thought process. At this moment we do not have the necessary tools for the selection (the key to utilize science) of knowledge. One of the best forms of selection is illustrated by the automatic telephone exchange. Section 6: There is a problem with selection. The main problem of it is the deficiency of the indexing systems. When data is recorded and put into storage, it is usually filed alphabetically or numerically. The human mind works differently. It works according to association. Instead of using selection by indexing, selection by association may be mechanized.

Alternatively, the technology has matured greatly and allows us to now produce complicated, yet cheap and dependable machines. Section 2: Science is really useful. However, in order to have it to be very efficient and useful it should not only be stored but also be frequently consulted and enhanced. In the future we would probably be able to store human writings in a small room with the use of photography. Section 3: Using the latest advances of speech recording and stenography, we will help soon be able to make printing immediate.
The advancement of photography is not going to stop. The thought process of repetition could be in relation to machine. Electrical machines will be the advancement of arithmetical computation. Section 4: There is more to the scientific reasoning than just arithmetic. There are a few machines that are not used for arithmetic, partly due to the markets needs. Solving higher mathematics require other repetitive processes of thought to be mechanized.
1 Improved technology has become an extension of our capabilities, much as how external hard drives function for computers so it may reserve more memory for more practical tasks. Another significant role of practicality in technology is the method of association and selection. "There may be millions of fine thoughts, and the account of the experience on which they are based, all encased within stone walls of acceptable architectural form; but if the scholar can get at only one a week by diligent search, his synthesis are not. Bush concludes his essay by stating that: The applications of science have built man a well-supplied house, and are teaching him to live healthily therein. They have enabled him to throw masses of people against one another with cruel weapons. They may yet allow him truly to encompass the great record and to grow in the wisdom of race experience.
He may perish in conflict before he learns to wield that record for his true good. Yet, in the application of science to the needs and desires of man, it would seem to be a singularly unfortunate stage at which to terminate the process, or to lose hope as to the outcome. — vannevar Bush 3 Outline edit many scientists, especially physicists, get new duties during the war. Now, after the war, they need new duties. Section 1: The use of Science has improved tremendously in many ways for humans. The knowledge of science has grown considerably. However, the way we manage it still remains the same for centuries. We are no longer able to use what Science finds out.

He argues that the instruments are at hand which, if properly developed, will give society access to and command over the inherited knowledge of the ages. The perfection of these pacific instruments, he suggests, should be the first objective of our scientists. 3 Through this process, society would be able to focus and evolve past the existing knowledge rather than looping through infinite calculations. We should be able to pass the tedious work about of numbers to machines and work on the intricate theory which puts them best to use. If humanity were able to obtain the "privilege of forgetting the manifold things he does not need to have immediately at hand, with some assurance that he can find them again if proven important" only then "will mathematics be practically effective in bringing the growing. 1 to exemplify the importance of this concept, consider the process involved in 'simple' shopping: "Every time a charge sale is made, there are a number of things to be done. The inventory needs to be revised, the salesman needs to be given credit for the sale, the general accounts need an entry, and most important, the customer needs to be charged." 1 due to the convenience of the store's central device which rapidly manage thousands. Indeed, as of today, "science has provided the swiftest communication between individuals; it has provided a record of ideas and has enabled man to manipulate and to make extracts from that record so that knowledge evolves and endures throughout the life of a race rather.
A library of a million volumes could be compressed into one end of a desk. — vannevar Bush 3 On the other hand, it still uses methods of indexing of information which Bush described as artificial: When data of any sort are placed in storage, they are filed alphabetically writer or numerically, and information is found (when it is) by tracing. It can be in only one place, unless duplicates are used. — vannevar Bush 3 This description resembles popular file systems of modern computer operating systems ( fat, ntfs, ext3 when used without hard links and symlinks, etc. which do not easily enable associative indexing as imagined by bush. Outlook in the use of science edit bush urges that scientists should turn to the massive task of creating more efficient accessibility to our fluctuating store of knowledge. For years inventions have extended people's physical powers rather than the powers of their mind.
some results in microfilm for scholarly purposes, and the potentialities are highly suggestive. — vannevar Bush 3 Concept realization edit "As we may think" predicted (to some extent) many kinds of technology invented after its publication, including hypertext, personal computers, the Internet, the world Wide web, speech recognition, and online encyclopedias such as wikipedia : "Wholly new forms. He believed people would create links between related articles, thus mapping the thought process and path of each user and saving it for others to experience. Wikipedia is one example of how this vision has in part been realized, allowing elements of an article to reference other related topics. A user's browser history maps the trails of possible paths of interaction, although this is typically available only to the user that created. Bush's article also laid the foundation for new media. Doug Engelbart came across the essay shortly after its publication, and keeping the memex in mind, he began work that would eventually result in the invention of the mouse, the word processor, the hyperlink and concepts of new media for which these groundbreaking inventions were. 1 Today, storage has greatly surpassed the level imagined by vannevar Bush, The Encyclopædia britannica could be reduced to the volume of a matchbox.
Shortly after the publication of this essay, bush coined the term " memex " in a letter written to the editor. 2, that letter became the body of "As we may think which added only an introduction and conclusion. As described, bush's memex was based on what was thought, at the time, to be advanced technology of the future: ultra high resolution microfilm reels, coupled to multiple screen viewers and cameras, by electromechanical controls. The memex, in essence, reflects a library of collective knowledge stored in a piece of machinery described in his essay as "a piece of furniture". 3, the, atlantic publication of Bush's article was followed, summary in the september 10, 1945 issue. Life magazine, by a reprint that showed illustrations of the proposed memex desk and automatic typewriter. (Coincidentally, the same issue. Life contained aerial photos of Hiroshima after the dropping of the atomic bomb, a project Bush was instrumental in starting).

Vannevar Bush as we may think " is a 1945 essay by, vannevar Bush which has been described as visionary and influential, anticipating many aspects of information society. It was first published. The Atlantic in July 1945 and republished in an abridged version in September 1945—before and after the atomic bombings of Hiroshima and Nagasaki. Bush expresses his concern for the direction of scientific efforts toward destruction, rather than understanding, and explicates a desire for a sort of collective memory machine with his concept pdf of the memex that would make knowledge more accessible, believing that it would help fix these. Through this machine, bush hoped to transform an information explosion into a knowledge explosion. 1, contents, concept creation edit, the article was a reworked and expanded version of Bush's essay "Mechanization and the record" (1939). Here, he described a machine that would combine lower level technologies to achieve a higher level of organized knowledge (like human memory processes).
