Reference excerpt

Patrick Gill is a British physicist who is a Senior NPL Fellow in Time & Frequency at the National Physical Laboratory (NPL) in the UK.

Education Gill was educated at the University of Sussex and the University of Oxford where he was awarded a Doctor of Philosophy degree in 1975 for research on Charge Transfer as a Laser Excitation Mechanism.

Research Gill's research is concerned with laser frequency stabilisation techniques for very high resolution spectroscopy, and the development of leading-edge optical atomic clocks that look to form the basis of a future redefinition of the SI base unit second. These include optical clocks based on laser-cooled single ions confined in radiofrequency traps and neutral atoms held in optical lattices, and which now reach uncertainties below that of the caesium fountain primary frequency standard. Additionally, he has developed a range of stable lasers and optical metrology instrumentation with application to high technology sectors such as precision engineering and manufacture, space science, satellite navigation, Earth observation, defence and security and optical telecommunications.

Awards and honours Gill is a Fellow of the Institute of Physics (FInstP) and was awarded their Young Medal and Prize in 2008 for world-leading contributions to optical frequency metrology. He also received the I. I. Rabi Award in 2007 from the IEEE International Frequency Control Symposium for contributions to time and frequency metrology and the realisation of single ion optical frequency standards. More recently, his group received the Royal Institute of Navigation's Duke of Edinburgh Award in 2014 for long term atomic clock development. Patrick is a visiting professor at Imperial College London and the University of Oxford. He was awarded an MBE for services to Science in The Queen's 2015 New Year Honours. Gill was elected a Fellow of the Royal Society (FRS) in 2016.

Worked examples

Example 1 — a first encounter with Patrick Gill (physicist)

Start with the simplest possible case. Write down what Patrick Gill (physicist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Patrick Gill (physicist) 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 Patrick Gill (physicist) 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 Patrick Gill (physicist)

In research: Patrick Gill (physicist) appears in physics 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 Patrick Gill (physicist) 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: Patrick Gill (physicist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academics of Imperial College London, Academics of the University of Oxford, Alumni of the University of Oxford, so understanding it makes those chapters shorter.
In everyday life: Look for Patrick Gill (physicist) 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.
