Ray Ison

Ray Ison is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ray Ison rather than just read about it. In short: Raymond L. Ison (born 3 July 1952, Bathurst, NSW, Australia) is an Australian-British cybernetician, systems scholar/scientist, and Professor emeritus of Systems at the Open University in the UK.

Key takeaways

Ray Ison belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ray Ison to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ray Ison from memory before moving on to harder problems.

Reference excerpt

Raymond L. Ison (born 3 July 1952, Bathurst, NSW, Australia) is an Australian-British cybernetician, systems scholar/scientist, and Professor emeritus of Systems at the Open University in the UK. He is also the former President of the International Federation for Systems Research (IFSR), from 2018-2026. He was also Professor Systems for Sustainability at Monash University, and fellow at the Centre for Policy Development, and President of the International Society for the Systems Sciences in the year 2014-15. He is known for his work on systems praxeology within rural development, sustainable management, systemic governance and the design and enactment of learning systems. David Russell, a psychotherapist and psychodynamic psychologist in private practice in Sydney and Blackheath, NSW, Australia, about Ray Ison: "All of Ison's professional work has been driven by a passion to maintain a flourishing and highly interactive life-world. His writings and research have given voice to this passion by consistently exemplifying an epistemology of action: How we know what we know; how this knowledge shapes ongoing experience; and how this experience is found to be satisfying or dissatisfying. His approach has been to focus on relationships and the networks in which they are embedded, namely, the systems."

Life and work From a background in Agricultural Science (University of Sydney) including plant ecophysiology and agronomy (University of Queensland) and systems agriculture, rural development and agricultural extension (Hawkesbury & University of Sydney) Ison has established himself as a major scholar and practitioner in the field of Systems Praxeology – the science of practical action grounded in systems thinking in practice (STiP). Ison's research and scholarship spans the biophysical and social and is primarily interdisciplinary and collaborative. He has made major contributions to systemic governance, particularly in the fields of water and river catchments based on social learning realised through STiP. Many of his publications can be seen or accessed by Open Research Online. Ison, who took up the Chair in Systems at The Open University (UK) in 1994, is only the third appointee to the Open University (OU) chair in Systems since the group was established in 1971 (the inaugural chair was John Beishon, followed by Derek Pugh). From 2008 to 2015 he was also Professor Systems for Sustainability at Monash University (School of Geography and the Monash Sustainability Institute) where he established and ran the Systemic Governance Research Program which now continues within the Applied Systems Thinking in Practice (ASTiP) group at the OU. Ison has been returned in all UK Research Assessment Exercises (now Research Excellence Framework or REF) with the OU Development Studies group (there is no category for Systems). In 2021 this will be Unit of Assessment 22, Anthropology and Development Studies. Building on his academic achievements Ison has gone on to hold major leadership roles within the international Systems and Cybernetics community. He is currently President of the International Federation for Systems Research (IFSR).

Worked examples

Example 1 — a first encounter with Ray Ison

Start with the simplest possible case. Write down what Ray Ison claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ray Ison before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ray Ison ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ray Ison

In research: Ray Ison appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ray Ison in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ray Ison is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1952 births, Academic staff of Monash University, Academics of the Open University, so understanding it makes those chapters shorter.
In everyday life: Look for Ray Ison outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
