Quiz Answer Key
Newton appropriated ancient and vague words like "force" and "motion," giving them new, quantifiable meanings suitable for mathematical formulas. This "purification" of language was essential for the advancement of physics and the success of the Scientific Revolution, as it provided a precise foundation for describing and understanding the physical world.
In an age where information is readily available and abundant, the ability to focus one's attention becomes a valuable and scarce resource. This shift stems from the overwhelming volume of data, which makes it challenging to discern meaningful and relevant information, thereby increasing the cost of focused engagement.
Vail's visit to the local newspaper office allowed him to analyse the frequency of letters used in print. He then collaborated with Morse to adjust the code in order to utilise the shortest combinations (dots and dashes) for the letters that were most frequently used.
A meme, in cultural evolution, is a replicator and propagator, similar to a gene, but for ideas, fashions, or theories. An example is the "jumping the shark" concept, which describes the moment a television show declines in quality, illustrating how ideas spread, mutate, and sometimes become culturally significant.
Gleick suggests that entropy, a measure of disorder or uncertainty, is intrinsically linked to information. Greater entropy implies more uncertainty, and thus more information is required to reduce that uncertainty and restore order, indicating that information can be seen as order imposed on disorder.
Ada Lovelace's notes were more general than the musings of Babbage. She realised that the Engine was capable of more than just mathematical operations. She was aware that it had the capacity to create music or manipulate language, meaning that it could theoretically manipulate anything.
Shannon's work established information theory, a mathematical framework for quantifying, storing, and communicating information. He defined information in terms of uncertainty and bits, abstracting it from meaning, which provided a universal measure applicable to various fields, including computing and communication.
Gleick states that biology has become an information science because genes act as instructions or code, which is similar to computing. DNA is the main message processor at the cellular level, using an alphabet and code to form a living being.
Redundancy, in Gleick's view, is the seemingly inefficient repetition of information that actually serves as an essential tool for clarity and error correction. By providing multiple cues and repeated elements, redundancy ensures that messages can still be understood even in the presence of noise or errors.
Carl Bridenbaugh warned against a "Great Mutation" due to the rapid changes in human existence brought about by technology and the decline of reading. He lamented the distancing from nature, the proliferation of technology (like radios and Kodak cameras), and the loss of a shared cultural foundation, suggesting a crisis of historical awareness and connection.

Analyse the impact of new media technologies on human thought and culture, drawing on examples and insights from Gleick's The Information.
Examine the role of redundancy in communication and information theory. How does redundancy contribute to effective communication, and what are its limitations?
Considering Gleick's exploration of information overload, discuss the challenges and opportunities presented by the abundance of information in the modern age.
Glossary of Key Terms
Bit: The fundamental unit of information, representing a binary digit (0 or 1).
Entropy: A measure of disorder, randomness, or uncertainty in a system. In information theory, entropy is related to the amount of information needed to describe the system.
Meme: A unit of cultural information, such as an idea, belief, or style, that is transmitted from one individual to another.
Redundancy: The inclusion of extra information that is not strictly necessary for communication, but that helps ensure accuracy and clarity.
Information Theory: A branch of mathematics and electrical engineering that studies the quantification, storage, and communication of information.
Gene: The basic unit of heredity, containing information that determines an organism's characteristics. Gleick uses the gene as an example of information storage.
Algorithm: A set of rules or instructions to be followed in calculations or other problem-solving operations, especially by a computer.
Maxwell's Demon: A thought experiment illustrating a potential violation of the second law of thermodynamics, where a "demon" uses information to sort molecules, reducing entropy.
Negative Entropy: The opposite of entropy; a measure of order, organisation, and complexity in a system. Used often in discussing living organisms.
Information Overload: A state of being overwhelmed by the amount of information available, making it difficult to process and make decisions.
