Vannevar bush as we may think summary book

Later, in conversation with a friend about how people resist innovation, he brings up the trail again, and then copies the whole trail out to be installed into his friend's memex. 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 New Media Reader. To study cosmic rays , physicists built vacuum tubes [ note 7 ] that could count at 0. Bush recognized a need for digital indexing of documents, that is, associating a machine-readable index code with each document, so that a machine could identify and retrieve a document from mass store automatically.

Two kinds of technologies can help: analog information on microfilms, and digital information encoded by electric signals. There, the trail is joined into a more general trail about how people resist innovation. Associative indexing can be implemented by coded dots printed on the bottoms of microfilms, and an optical reader can read the printed code and electrically signal the memex to pull up the next item.

Note the automatic telephone exchange, which has hundreds of thousands of such contacts, and yet is reliable.

For that matter, even modern great libraries are consulted by few. This can be done when the user is building a trail. Log in now. However, whiteprint technology [ note 4 ] might be miniaturized, leading to miniature dry photography. Outlook in the use of science [ edit ]. And then trying to work out the logistics. Soon, technologies will exist that can help people do intellectual labor better and faster.

Section 3: Not only will it be cheap to transmit and copy digital material, it will also be cheap to convert printed material into digital form. On the other hand, it still uses methods of indexing of information which Bush described as artificial:. Memex does an important step, it not only helps in searching and locating the data but also provide a platform to tie two items together.

Article Talk. A library of 1 million books would occupy the volume of books, which can fit on a bookshelf. Wikipedia is one example of how this vision has in part been realized, allowing elements of an article to reference other related topics. 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.

Indeed, Bush was very concerned with information overload inhibiting the research efforts of scientists. References [ edit ]. Bush proceeds to describe in detail a management system for a department store , where a salesperson enters customer and product information, which a central machine uses to update inventory, credit sales, adjust accounts, and charge customers, using analog devices such as punched cards, dry photography, microfilms, Valdemar Poulsen 's magnetic wire recorder , and so on.

This unified, searchable storage founded a key component of memex described in the next part. While currently Vocoders need human operators, a future Vocoder could transcribe speech automatically. 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.
