Jehane Ragai

Jehane Ragai is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jehane Ragai rather than just read about it. In short: Jehane Noureldin Ragai (Arabic: جيهان نور الدين رجائي) (born in Cairo, Egypt) is an Emeritus Professor of Chemistry at the American University in Cairo (AUC). She is the author of the two editions of The Scientist and the Forger.

Key takeaways

  • Jehane Ragai belongs to chemistry; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Jehane Ragai to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Jehane Ragai from memory before moving on to harder problems.

Reference excerpt

Jehane Noureldin Ragai (Arabic: جيهان نور الدين رجائي) (born in Cairo, Egypt) is an Emeritus Professor of Chemistry at the American University in Cairo (AUC). She is the author of the two editions of The Scientist and the Forger. The first edition, published in 2015 by Imperial College Press, was translated into Korean. The second edition, published in 2018 by World Scientific Publishing, was translated into Chinese. Her recent Textbook Technical Art History, published in 2021 by World Scientific Publishing, which she co-authored with Tamer Shoeib has won the "Most Promising New Textbook Award " by the Textbook and Academic Authors Association in the US.

Early life and education Jehane Ragai was born in Cairo, Egypt and is the daughter of Doria Shafik (1908–1975), the suffragette and leader of the Egyptian feminist movement from the mid 1940s to the mid 1950s and of the lawyer Nour eldin Ragai (1914–1980). Ragai obtained the French Baccalaureate from the French Lycee in Cairo, a B.Sc. in Chemistry in 1966 (magna cum laude) and an M.Sc. in Solid State Science (1968) both from the American University in Cairo. In 1976 she received her doctoral degree from Brunel, the University of West London in the UK.

Career Ragai was a faculty member in the Chemistry Department of the American University in Cairo (AUC) from 1970 until her retirement as an Emeritus Professor in 2015. Ragai's research interest is mainly in surface chemistry and her published work deals with the gas/solid and liquid/solid interfaces. She also has a keen interest in archaeological chemistry and has published several articles that deal with the interaction of the humanities and the science. She has chaired the AUC University Senate (1998–2000), the AUC Chemistry Department (2000–2006) and was a principal investigator, leading the surface chemistry research group at the Youssef Jameel Science and Technology Research Center (STRC) at AUC. She was the director of the AUC Chemistry Graduate program (2010-Fall 2014). Ragai is the recipient of several AUC Trustees merit awards as well as the School of Sciences and Engineering award for her role as chair of the chemistry department. In 2013 she received the university-wide best teacher award. Given her additional interest in archaeological chemistry she was a consultant to the American Research Center in Egypt (ARCE) Sphinx project, has served on the National Committee for the Study of the Sphinx, and for seven years (2001–2008) was member of the Board of Governors of the ARCE. As part of this project she studied the properties of ancient Egyptian mortars from the Sphinx and the Kephren Valley Temple. Ragai was for several years (2008–2020) a member of the International Awards Jury in the Physical Sciences for the L'Oréal-UNESCO Awards for Women in Science founded by Nobel laureates Christian de Duve and Pierre Gilles de Gennes. She was an invited lecturer at the following universities: Cambridge (UK), Cornell, Exeter, North Carolina at Raleigh, Princeton, Rutgers, Lund, Gothenburg, and Cardiff; also at the American Philosophical Society, the Mahmoud Khalil museum in Cairo, the American University in Paris, the Fitzwilliam Museum in Cambridge (UK), and the CNRS in Marseille. She has recently been elected as a foreign member of the Royal Swedish Academy of Arts and Sciences in Gothenburg.

Family She has two daughters from her marriage to Ali Tosson Islam (1945–1999). In April 2010, she married Sir John Meurig Thomas (1932–2020).

Worked examples

Example 1 — a first encounter with Jehane Ragai

Start with the simplest possible case. Write down what Jehane Ragai 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 Jehane Ragai 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 Jehane Ragai 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 Jehane Ragai

In research
Jehane Ragai 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 Jehane Ragai 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
Jehane Ragai is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1944 births, 20th-century Egyptian archaeologists, 20th-century Egyptian women scientists, so understanding it makes those chapters shorter.
In everyday life
Look for Jehane Ragai 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.
