Each term has its own page in the DICTIONARY and starts with a brief definition.
Bullet points follow the definition and provide both context and detail.
Links embedded in the text throughout the site (highlighted in blue) link back to DICTIONARY entries.
Shorter summaries of terms also appear on DIAGRAM pages under the heading SOME KEY TERMS. These entries strip definitions back to basics and can be viewed leaving the page.
Why a dictionary of light, colour & vision
One of the practical objectives of this website is to make the connections between the topics of light, colour and vision accessible to students and researchers of all ages.
Our DICTIONARY aims to avoid a problem faced by websites such as Wikipedia where articles are often composed by contributors with narrow specialization and their own topic-specific vocabulary.
The layout of the DICTIONARY also aims to avoid situations where a single unknown word or phrase makes it difficult, if not impossible, for our visitors to make sense of the content (as explained below).
Terms, definitions and explanations
All the terms we have selected are widely used and are applied consistently across the topics of light, colour and vision.
The definitions and explanations avoid topic-specific vocabulary and terms with different meanings in different fields.
As far as possible definitions contain no more than two short sentences.
Embedded links (highlighted in blue) connect to explanations of terms that might be unfamiliar.
The explanations that follow each definition are arranged as short bullet points and avoid paragraphs of information completely.
Each bullet makes a stand-alone point and is intended to deal with a single piece of information that we believe is likely to be important to our readership.
Because our readership is diverse, a series of bullet points often provide different perspectives on a single term or topic.
