多学科概述
“Interdisciplinarity” in referring to an approach to organizing intellectual inquiry is an evolving field, and stable, consensus definitions are not yet established for some subordinate or closely related fields.
An interdisciplinary community or project is made up of people from multiple disciplines and professions who are engaged in creating and applying new knowledge as they work together as equal stakeholders in addressing a common challenge. The key question is what new knowledge (of an academic discipline nature), which is outside the existing disciplines, is required to address the challenge. Aspects of the challenge cannot be addressed easily with existing distributed knowledge, and new knowledge becomes a primary subgoal of addressing the common challenge. The nature of the challenge, either its scale or complexity, requires that many people have interactional expertise to improve their efficiency working across multiple disciplines as well as within the new interdisciplinary area. An interdisciplinarary person is a person with degrees from one or more academic disciplines with additional interactional expertise in one or more additional academic disciplines, and new knowledge that is claimed by more than one discipline. Over time, interdisciplinary work can lead to an increase or a decrease in the number of academic disciplines.

The technology revolution is upon us. In the past, there have been many triumphs in the world of technology. To this date, people are able to communicate over thousands of miles with the greatest of ease. The Internet connects nearly 400 million users worldwide and is an essential part of how we work, play, communicate, and conduct commerce. We use the Internet in ways that seemed unimaginable in the past.
The Internet provides convenience for people to learn at home. Internet based training has become a common business tool used to gain advancements in current jobs. Tutoring over the Internet is also available. Business on the Internet is a growing technology. Business on the Internet has no geographic boundaries; it has access to more consumers. Approximately 150 businesses join the Internet every day. There is less labor force needed and it is open 24 hours a day. The Internet is also a bigger and cheaper way to advertise. In the past 20 years, the Internet has changed a number of areas in society, especially the business world. In the last 40 years, the Internet has gone from a method of defense communication for the government, to a business venture for an entrepreneur or a fortune 500-company. The Internet is a way for gaining consumers, products and capital for a business.

The Internet has many great uses, but, as anything else, negative things can be done there as well. The beauty of the Internet is that it is so large that it's nearly impossible to keep track of what bad things everyone is doing. A few examples are someone can steal a cell phone and then by using the internet, they can reprogram the telephone to work off someone's account and not be traced. Other examples are the pirates of softwares. Someone can get a program that Microsoft sells for about one thousand dollars for free and it can't be traced. There is another fact that nearly anything can be traded online, like drugs, weapons such as high power guns, bombs, and the list for these items goes on and on. One of the worst things that the police really want to get their hands on is Child Pornography. It is not so hard to keep track of when people had to go out and hand deliver this stuff, but through the Internet the scum who partake in this don't have to leave their homes. A big problem is the fact that underage kids can see what they are not meant to. This does not just end up back at porn though; there are images of extreme violence on humans and animals. These images are not allowed to be viewed by anyone in Canada. However, different countries have different laws, and something that is not allowed here can easily be viewed by someone from a site in another country.
