Reference excerpt

Rosanna Diane Davison (born 17 April 1984) is an Irish actress, singer, writer, model and beauty queen who was crowned Miss World 2003. She is the daughter of musician Chris de Burgh, and the song "For Rosanna" was written by her father for his eighth studio album, Into the Light (1986) in her honour. Davison is a qualified nutritional therapist and promotes the health benefits of a plant-based diet.

Career In August 2003, she entered the Miss Ireland finals in Dublin, and winning the competition, found herself competing for the title of Miss World. December 2003 saw Davison, along with 106 other contestants, compete in the Miss World competition in Sanya, China. Rosanna went on to win the crown and is the first Irish entrant to win the Miss World title since it started in 1951. During Davison's reign, she visited the United Kingdom, the United States, Canada, China, and Sri Lanka.

In February 2012, she came second in a poll to find Ireland's most desirable Valentines. In the same year, she appeared on the October German issue of Playboy magazine. From October 2013, she started presenting slots on LFC TV, the dedicated television channel for Liverpool F.C. In December 2023, Davison was announced as one of the eleven celebrities taking part in the seventh season of Dancing with the Stars.

Personal life Born in County Dublin, Ireland, Davison's primary school education was at Aravon School, in County Wicklow. She then attended Rathdown School in Glenageary, County Dublin. She was class prefect before graduating and completing her leaving certificate examinations in 2002. Davison has been in a relationship with Wesley Quirke since 2006. They were engaged in 2013 and wed in the summer of 2014. They had their honeymoon in the Seychelles. They have one daughter, and twin sons. Davison is a graduate of the College of Naturopathic Medicine. She is a qualified nutritional therapist and obtained her MSc degree in personalised nutrition from Middlesex University. In February 2015 she signed a publishing deal with Gill Books for her first cookbook, Eat Yourself Beautiful, which was released in August 2015 and went on to be a best-seller. The book advocates plant-based nutrition. Davison has previously collaborated with People for the Ethical Treatment of Animals (PETA) on multiple occasions to promote the benefits of vegetarian and vegan diets. In 2019, Davison was criticised by vegan activists for taking part in a paid campaign for Naas Racecourse. In response, Davison stated that although she eats a plant-based diet for both health and ethical reasons, she has never claimed to be a "lifestyle vegan".

Worked examples

Example 1 — a first encounter with Rosanna Davison

Start with the simplest possible case. Write down what Rosanna Davison 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 Rosanna Davison 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 Rosanna Davison 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 Rosanna Davison

In research: Rosanna Davison 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 Rosanna Davison 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: Rosanna Davison is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1984 births, Actresses from County Dublin, Actresses from County Wicklow, so understanding it makes those chapters shorter.
In everyday life: Look for Rosanna Davison 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.
