Key takeaways

  • Sam Hay (chemist) belongs to chemistry; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.

  • Reproduce the core statement of Sam Hay (chemist) from memory before moving on to harder problems.

Reference excerpt

Sam Hay is a chemist from New Zealand and a Professor of Biophysical Chemistry in the Department of Chemistry and Manchester Institute of Biotechnology (MIB) at The University of Manchester. His research in general is based on computational chemistry and theoretical chemistry, specifically on the areas of In silico Enzymology, quantum mechanics roles in biological processes, kinetic modelling of complex reactions and high pressure spectroscopy.

Education Hay completed his Bachelor of Science degree in biochemistry in 2000 at University of Otago. He then joined the Australian National University for his Doctor of Philosophy degree and successfully completed it in 2004, and his work published in 2005. His PhD on Protein engineering of novel porphyrin/quinone-binding proteins for light-induced electron transfer was supervised by Prof. Thomas Wydrzynski.

Research and career Upon completing his PhD, Hay undertook postdoctoral research as a Wenner - Gren visiting Post Doctoral Fellow at Stockholm University where he spent time doing research on electrochemistry from 2004 to 2005. He then joined the University of Manchester and worked with Prof. Nigel Scrutton as a Post Doctoral Research Associate. In 2010, he became a Research Fellow at the University of Manchester, and in 2017 promoted to the position of Senior Lecturer. In 2019, he was promoted to the position of Reader and in 2021, he was promoted to Professor. Hay's research is generally based on computational chemistry and theoretical chemistry, specifically on the areas of In silico Enzymology, quantum mechanics roles in biological processes, kinetic modelling of complex reactions and high pressure spectroscopy.

Notable work In 2012, Hay and Nigel Scrutton published a paper on how vibrations may affect enzyme-catalyzed reactions. The paper provided an insight to motions which may reduce the size of the energy barrier along the reaction coordinate which may aid hydrogen-transfer reactions. The roles of these comprehensive motions and the understanding of the structural origins to these motions were not previously researched, and indirect experimental evidence and computational simulations were used to aid provide the insight into these good vibrations or motions. In 2015, Hay also participated in research which first published a paper on a new, soluble, oxygen tolerant reductive dehalogenase enzyme. Organohalides in general contribute to a large proportion of environmental pollutants and the enzyme reductive dehalogenase is responsible for the biological dehalogenation in organohalide respiring bacteria. However, some of these enzymes are usually membrane associated and oxygen sensitive and therefore inhibits the process of dehalogenation, which the enzyme published upon was able to overcome.

Worked examples

Example 1 — a first encounter with Sam Hay (chemist)

Start with the simplest possible case. Write down what Sam Hay (chemist) 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 Sam Hay (chemist) 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 Sam Hay (chemist) 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 Sam Hay (chemist)

In research
Sam Hay (chemist) 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 Sam Hay (chemist) 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
Sam Hay (chemist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century New Zealand chemists, Australian National University alumni, Chemists of the University of Manchester, so understanding it makes those chapters shorter.
In everyday life
Look for Sam Hay (chemist) 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.
