Reference excerpt

Martin Lloyd Williams (22 November 1947–21 September 2020) was a Welsh chemist and environmental scientist who made important contributions to the science of air pollution and its incorporation into public policy in the United Kingdom. Williams was one of the first scientists to recognize the harmful health effects of ground-level ozone, in papers published in Nature in the mid-1970s, and one of the first to study vehicle emissions in the real world (rather than under artificial laboratory conditions). He also established the first systematic programme to produce inventories of UK national air pollution emissions.

Early life Born in Mountain Ash, Williams studied chemistry at University College, Cardiff, took a Ph.D. at Bristol University, and held research fellowships at the University of British Columbia and the University of Bradford.

Government career In 1975, he became a government scientist at the Department of Industry's environmental research centre, Warren Spring Laboratory in Stevenage, and served as Head of the Air Pollution Division there, leading a team of 50 scientists, from 1982 to 1993. He moved to the UK government's Department of Environment in 1993. In 2005, he became head of the air quality and science programme at the Department for Environment, Food and Rural Affairs, where he focused on translating air pollution science into effective government policy, and developed three national air quality strategies for the UK.

Academic career In 2010, Williams returned to academia as a professor and Head of Science Policy and Epidemiology in the Environmental Research Group at King's College London, where his research interests included the air quality in London, the measureable health benefits of improved air quality, and the connections between climate change and air pollution. He was also a visiting professor at the University of Urbino, Italy.

Other activities Apart from his government and academic appointments, he was chair of the scientific arm of the UN Convention on Long-Range Transboundary Air Pollution (CLRTAP), co-chair of the World Health Organization (WHO) working group on air quality guidelines, an air quality adviser to the US Environmental Protection Agency, and a member of the UK government's two scientific, air pollution advisory committees (AQEG and COMEAP). In 2019, he became one of three Clean Air Champions (alongside Sir Stephen Holgate and Jenny Baverstock) appointed by the UK government's Clean Air programme, tasked with using scientific research to inform practical solutions to the problem of air pollution. Shortly before his death, the Institute of Air Quality Management invited him to be its inaugural Honorary Fellow. Williams died in 2020 of the heart condition hemopericardium.

Worked examples

Example 1 — a first encounter with Martin Williams (environmental scientist)

Start with the simplest possible case. Write down what Martin Williams (environmental scientist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Martin Williams (environmental 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 Martin Williams (environmental 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 Martin Williams (environmental scientist)

In research: Martin Williams (environmental scientist) appears in chemistry 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 Martin Williams (environmental 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: Martin Williams (environmental scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1947 births, 2020 deaths, Air pollution in the United Kingdom, so understanding it makes those chapters shorter.
In everyday life: Look for Martin Williams (environmental 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.
