This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand John Williams (water scientist) rather than just read about it. In short: John Williams is an Australian scientist whose life work has been in the study of hydrology and the use of water in the landscape and farming, including land salinity. Biography Williams grew up near Tumbarumba on a farm in the Snowy Mountains region of New South Wales.

Key takeaways

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

Reference excerpt

John Williams is an Australian scientist whose life work has been in the study of hydrology and the use of water in the landscape and farming, including land salinity.

Biography Williams grew up near Tumbarumba on a farm in the Snowy Mountains region of New South Wales. He attended school in Queanbeyan near Canberra, before graduating from the University of Sydney with a degree in agricultural science and a doctorate in soil science and hydrology. Williams is a founding member of the Wentworth Group of Concerned Scientists and advocated for a rational debate on Australia's water resources. He was Chief of the Division of Land and Water, CSIRO (Australia's premier government research organisation), in Canberra, when he retired in 2004. He served earlier at the CSIRO laboratories at Townsville in Queensland where, among other things, he studied the Great Artesian Basin and the transport of water from the Great Dividing Range into the outback of Queensland and New South Wales. He also served as adjunct professor in Agriculture and Natural Resource Management at Charles Sturt University, and Chief Scientist and Chair of the NSW Department of Natural Resources’ Science and Information Board. Williams was also Commissioner of the New South Wales Natural Resources Commission between 2005 and 2011. Williams is an emeritus professor and research associate at the Australian National University; and a commentator on environmental matters. In a feature article in a July 2009 edition of The Canberra Times Williams reportedly stated that there should be a sixty percent cut in water use across the Murray-Darling Basin, and the Snowy Mountains Scheme that diverts water to the Riverina should not be exempt from water savings. In 2012, Williams was interviewed for commentary on the Murray-Darling Commission report. During his career, Williams has been honoured with the 2005 Farrer Memorial Medal for achievement and excellence in agricultural science and appointed in November 2011 as a Fellow of the Australian Academy of Technological Sciences and Engineering (FTSE). In February 2018, Williams was a co-author of an article in The Conversation and co-signatory of the Murray Darling Declaration along with other concerned scientists.

Worked examples

Example 1 — a first encounter with John Williams (water scientist)

Start with the simplest possible case. Write down what John Williams (water scientist) 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 John Williams (water scientist) 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 John Williams (water scientist) 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 John Williams (water scientist)

In research: John Williams (water scientist) 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 John Williams (water scientist) 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: John Williams (water scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Australian scientists, Academic staff of Charles Sturt University, Academic staff of the Australian National University, so understanding it makes those chapters shorter.
In everyday life: Look for John Williams (water scientist) 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.
