The efficient one-to-many, one-to-one, and many-to-many communication links provided by the Internet and WWWare reinventing the book into a new information system that is tightly interconnected, fast-paced, and inexpensive. The coreconcept is the idea of a digital commons , a vast repository of richly inter-linked hypertext materials that is woven and tended bya multitude of authors worldwide. In the digital commons, authors can form communities to collaborate and continuously improve, re-use, and re-organize the material in the commons. The communityculture created by this system could have some of the attributes of the “collective intelligence” of Levy, Engelbart, Licklider,Barabási, Weinberger, and others where the resulting whole is greater than the sum of its parts. The readers of the commons arealso more tightly connected by communications technologies (email, discussion forums, chat rooms, blogs, wikis, and so on). If currentlibraries can be compared to Eric Raymond’s cathedrals, then the future digital commons will be like a bazaar.

“… humanity has a chance to reclaim its future. Not by placing its destiny in the hands of some so-calledintelligent mechanism, but by systematically producing the tools that will enable it to shape itself into intelligent communities,capable of negotiating the stormy seas of change.” [Levy p. xxv]

In contrast to traditional libraries, the digital commons is global and under continual, 24/7 expansion andrevision. And, in sharp contrast to the “tragedy of the commons” often cited in the literature, this is a commons without anecessary tragedy; indeed, as its use grows, Metcalfe’s Law (which holds that the usefulness, or utility, of a network is proportionalto the square of the number of users) will amplify its effect. The digital commons will provide new opportunities for writing,scholarship, reading, and learning.

… primary and secondary materials will interact more powerfully than before as both are online side byside. Scholarly discussions will quote the original by pointing to it, and leave the reader to explore the original context, not justthe few words or sentences most apposite. Conversely, texts will acquire structured commentaries not by single hands but organizedout of the work of many. [O’Donnell, pp. 132-4]

Indeed, this new format turns out to be similar to some of the modern (or postmodern) ideas in literary,social, and philosophical theory. Landow, Haraway, Hayles, and others have written on this.

Two pillars support the emerging digital commons. The first is a common technology framework for sharing information provided by hypertext, HTML, XML, and the WWW. Thesecond is a common legal framework for sharing information provided by open-access licenses.

Open-access takes its inspiration from the free software and open-source software movements, in whichcommunities of programmers create software such as the Linux operating system, Apache web server, and Mozilla family of browsersand mail tools. When a community is successful, a high-quality piece of work emerges from the open development process, thanks tomany hands to do the work, many eyes to conduct a constant peer review, and pride of authorship and contributions to thecommunity.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
