Reference excerpt

Merieme Chadid (Arabic: مريم شديد; born 11 October 1969 in Casablanca) is a Moroccan-French astronomer, explorer and astrophysicist. She leads international polar scientific programs and has been committed to installing a major astronomical observatory at the heart of Antarctica.

Education and early life Chadid was born October 11, 1969, in Casablanca to a Moroccan family. Her father and mother were a blacksmith and a housewife respectively. She was one of seven children. At 12 years old, she discovered her love of astronomy from a Johannes Kepler book gifted to her by her brother. In 1992, Chadid graduated from the University of Hassan II Casablanca with a master's degree in Physics and Mathematics. In 1993, she graduated from the University of Nice Sophia Antipolis with a Master of Advanced Studies and three years later earned her PhD in Astronomy and Space from the Paul Sabatier University from her research detecting hypersonic shock waves in pulsating stars and explaining their origin. She also obtained the highest university qualification degree Habilitation HDR, a second PhD, at the University of Nice Sophia-Antipolis. Chadid completed several executive education programs at John F. Kennedy School of Government, Harvard University as well.

Career Merieme Chadid joined the Centre national de la recherche scientifique and then the European Southern Observatory soon after earning her PhD. She worked on European Southern Observatory for the installation of The Very Large Telescope, the largest telescope in the world at the time, in the Atacama Desert in northern Chile. She works as an astronomer in the French public university system. Chadid is President of the International Astronomical Union Division G, Stars and Stellar Physics, having previously served as its Vice-President from 2021 to 2024 and as a steering committee member from 2018 to 2021. Chadid became the first Moroccan as well as the first female French astronomer to reach the heart of Antarctica, and the first to plant an Arab and an African flag (the Moroccan flag) in Antarctica in 2005 when she achieved her first polar expedition to set up a new observatory. Of her many achievements, her most treasured accomplishment has been her work under extreme conditions in the heart of Antarctica. She is considered the world's first astronomer to be committed to installing the large astronomical observatory in Antarctica, where she carried out pioneering work. In interviews, she has compared the installation of the observatory to a space mission, an area characterized by only a thin layer of turbulence, making it easier to observe faraway objects than observatories in other parts of the world. As night continues for several months of the year, researchers at the Antarctica stations are able to study the stars 24/7. Chadid promotes education by giving lectures, attending conferences, supervising students, and her documentary on astronomy, Tarik Annujah, has played on the Al Jazeera Children's Channel. Her most published research aims to understand and decipher early star formation and the stellar evolution and pulsation towards of understanding of the Universe. She was listed by Forbes magazine as one of the thirty most interesting and fascinating workers in the world.

Personal life Merieme Chadid has been married to Jean Vernin, Director of Research of Centre National de Recherche Scientifique, since 31 March 2001; they have two children.

Worked examples

Example 1 — a first encounter with Merieme Chadid

Start with the simplest possible case. Write down what Merieme Chadid 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 Merieme Chadid 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 Merieme Chadid 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 Merieme Chadid

In research: Merieme Chadid 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 Merieme Chadid 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: Merieme Chadid is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1969 births, 21st-century French scientists, 21st-century French women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Merieme Chadid 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.
