"As a scientific illustrator, one must be able to convey a detailed, clear and accurate depiction of a specimen. Scientific illustrations are an important part of the documentation that makes a specimen museum-quality - along with field and research notes, accession records, photographs, and correspondence about the specimen. A scientific illustration captures information about a plant or animal, information that is often missing from the museum specimen. Scientific illustrations depict the scientifically important features of the organism being studied. They often also describe that organism's natural environment."

"One of the first designs of the information theory is the model of communication by Shannon and Weaver. Claude Shannon, an engineer at Bell Telephone Laboratories, worked with Warren Weaver on the classic book ‘The mathematical theory of communication’. In this work Shannon and Weaver sought to identify the quickest and most efficient way to get a message from one point to another. Their goal was to discover how communication messages could be converted into electronic signals most efficiently, and how those signals could be transmitted with a minimum of error. In studying this, Shannon and Weaver developed a mechanical and mathematical model of communication, known as the 'Shannon and Weaver model of communication'. ...
Shannon and Weaver broadly defined communication as 'all of the procedures by which one mind may affect another'. Their communication model consisted of an information source: the source’s message, a transmitter, a signal, and a receiver: the receiver’s message, and a destination. Eventually, the standard communication model featured the source or encoder, who encodes a message by translating an idea into a code in terms of bits. A code is a language or other set of symbols or signs that can be used to transmit a thought through one or more channels to elicit a response in a receiver or decoder. Shannon and Weaver also included the factor noise into the model. The study conducted by Shannon and Weaver was motivated by the desire to increase the efficiency and accuracy or fidelity of transmission and reception. Efficiency refers to the bits of information per second that can be sent and received. Accuracy is the extent to which signals of information can be understood. In this sense, accuracy refers more to clear reception than to the meaning of message. This engineering model asks quite different questions than do other approaches to human communication research."
