Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.

Soft matter is a subfield of condensed matter comprising a variety of physical states that are easily deformed by thermal stresses or thermal fluctuations. They include liquids, colloids, polymers, foams, gels, granular materials, and a number of biological materials. These materials share an important common feature in that predominant physical behaviors occur at an energy scale comparable with room temperature thermal energy. At these temperatures, quantum aspects are generally unimportant. Pierre-Gilles de Gennes, who has been called the "founding father of soft matter," received the Nobel Prize in physics in 1991 for discovering that the order parameter from simple thermodynamic systems can be applied to the more complex cases found in soft matter, in particular, to the behaviors of liquid crystals and polymers.
A blind or blinded experiment is a test or experiment in which information about the test that might lead to bias in the results is concealed from the tester, the subject, or both until after the test. Bias may be intentional or unconscious. If both tester and subject are blinded, the trial is a double-blind trial.
For example, when asking consumers to compare the tastes of different brands of a product, the identities of the product should be concealed – otherwise consumers will generally tend to prefer the brand they are familiar with. Similarly, when evaluating the effectiveness of a medical drug, both the patients and the doctors who administer the drug may be kept in the dark about the dosage being applied in each case, to forestall any placebo or nocebo effect, observer bias, or conscious deception.
New Coke was the reformulation of Coca-Cola introduced in 1985 by The Coca-Cola Company to replace the original formula of its flagship soft drink, Coca-Cola (also called Coke). New Coke originally had no separate name of its own, but was simply known as "the new taste of Coca-Cola" until 1992 when it was renamed Coca-Cola II.
The American public's reaction to the change was negative and the new cola was a major marketing failure. The subsequent reintroduction of Coke's original formula, re-branded as "Coca-Cola Classic", resulted in a significant gain in sales. This led to speculation that the introduction of the New Coke formula was just a marketing ploy; however the company has always claimed it was merely an attempt to replace the original product.
The Pepsi Challenge has been an ongoing marketing promotion run by PepsiCo since 1975. It is also the name of a cross country ski race at Giant's Ridge Ski Area in Biwabik, Minnesota, an event sponsored by Pepsi.
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks.
Most traditional communications media including telephone, music, film, and television are being reshaped or redefined by the Internet, giving birth to new services such as voice over Internet Protocol (VoIP) and Internet Protocol television (IPTV). Newspaper, book and other print publishing are adapting to website technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.
