Marina Galand

Marina Galand is a physics 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 Marina Galand rather than just read about it. In short: Marina Galand is a planetary scientist and professor at Imperial College London. She is the 2018 recipient of the Holweck Prize for her "outstanding contribution to space physics by studying in a comprehensive and original manner the effects of energy sources on planetary atmospheres throughout the Solar System and beyond".

Key takeaways

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

Reference excerpt

Marina Galand is a planetary scientist and professor at Imperial College London. She is the 2018 recipient of the Holweck Prize for her "outstanding contribution to space physics by studying in a comprehensive and original manner the effects of energy sources on planetary atmospheres throughout the Solar System and beyond".

Education Galand grew up in France and studied at the Université Joseph Fourier in Grenoble. There she completed a PhD in 1996 entitled "Transport des protons dans l'ionosphère aurorale". Galand completed two postdoctoral fellowships in Boulder, Colorado, in the Space Environment Centre (NOAA) and High Altitude Observatory (NCAR). She joined Boston University as a Research Associate in 2000.

Research In 2005, Galand joined Imperial College London as a lecturer in the Space and Atmospheric Physics Group. She became a Reader in 2016. Galand develops kinetic and fluid models to predict and interpret the observations from space probes, including Rosetta, Cassini-Huygens, and Venus Express. She used data from the recent Rosetta mission to comet 67P to fully determine the ion composition and make-up of cometary plasma around the nucleus. At the end of the 20-year Cassini mission, Galand expressed her excitement for the data, "...we are deeply excited by the dataset which Cassini has been returning over the past weeks due to its uniqueness (e.g., first ever in situ gas and plasma measurements in the upper atmosphere of a giant planet). This dataset is filled with unanticipated findings". Today she is a co-investigator for the plasma and UV instruments for the European Space Agency JUICE (Jupiter Icy Moons Explorer) 2022 mission, which will target the moon Ganymede.

Awards and fellowships 2005: Elected Fellow of the Royal Astronomical Society 2006: Zeldovich Medal from the Committee on Space Research 2017: Elected Fellow of the Institute of Physics 2017: Imperial College London Student Academic Choice Awards Best Teaching for Undergraduates 2018: Fernand Holweck Medal and Prize, Institute of Physics and the French Physical Society 2023: Royal Astronomical Society James Dungey Lecture

Public engagement Galand is involved with activities to increase the public's interest in space science. She participated to “A Comet Revealed” at the Royal Society Summer Exhibition in 2016 and “Catch A Comet” in 2014. Her research group has also run stands at the Imperial College Festival, which recently celebrated the finale of the Cassini spacecraft.

Worked examples

Example 1 — a first encounter with Marina Galand

Start with the simplest possible case. Write down what Marina Galand claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Marina Galand 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 Marina Galand 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 Marina Galand

In research: Marina Galand appears in physics 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 Marina Galand 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: Marina Galand is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century French physicists, 20th-century French women scientists, 20th-century women physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Marina Galand 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.
