Reference excerpt

Michael Dominic Richard Guiry (born 1949), is an Irish botanist, who specialises in phycology (algae). He is the founder and director of the algal database, AlgaeBase. He is a graduate of both University College Cork and the University of London. In addition to his interest in the taxonomy and the databasing of algae, his algal site promotes the sustainable use of seaweed resources. Since 2009, he has been an emeritus professor at the Ryan Institute, National University of Ireland, in Galway. The standard author abbreviation Guiry is used to indicate this person as the author when citing a botanical name.

Worked examples

Example 1 — a first encounter with Michael D. Guiry

Start with the simplest possible case. Write down what Michael D. Guiry claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Michael D. Guiry 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 Michael D. Guiry 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 Michael D. Guiry

In research: Michael D. Guiry appears in science 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 Michael D. Guiry 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: Michael D. Guiry is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1949 births, 20th-century Irish botanists, 21st-century Irish botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Michael D. Guiry 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.
