The Lippmann Islands are a group of small islands 2 nmi in extent, lying close northwest of Lahille Island off the west coast of Graham Land, Antarctica.
 They were originally mapped as a single island by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, and named by him for French physicist and Nobel Prize winner Gabriel Lippmann.
Antoine Henri Becquerel (15 December 1852 – 25 August 1908) was a French physicist, Nobel laureate, and the first person to discover evidence of radioactivity.
 For work in this field he, along with Marie Skłodowska-Curie and Pierre Curie, received the 1903 Nobel Prize in Physics.
 The SI unit for radioactivity, the becquerel (Bq), is named after him.
The Huygens–Fresnel principle (named after Dutch physicist Christiaan Huygens and French physicist Augustin-Jean Fresnel) is a method of analysis applied to problems of wave propagation both in the far-field limit and in near-field diffraction.
Coulometry is the name given to a group of techniques in analytical chemistry that determine the amount of matter transformed during an electrolysis reaction by measuring the amount of electricity (in coulombs) consumed or produced.
 It is named after Charles-Augustin de Coulomb.
Petit is a small, bowl-shaped lunar crater that is located on the northwestern edge of the Mare Spumans.
 The crater has a prominent ray system.
 The name is appropriate, since Petit means small in French.
 But it was actually named in honor of Alexis Thérèse Petit, a French physicist.
Peltier Channel ( ) is a channel 6 nautical miles (11 km) long, in a NE-SW direction, separating Doumer and Wiencke Islands to the south of Port Lockroy, in the Palmer Archipelago.
 Discovered by the French Antarctic Expedition, 1903–05, and named by Charcot for Jean Peltier, noted French physicist.
Charles-Augustin de Coulomb (] ; 14 June 1736 – 23 August 1806) was a French physicist.
 He was best known for developing Coulomb's law, the definition of the electrostatic force of attraction and repulsion, but also did important work on friction.
 The SI unit of electric charge, the coulomb, was named after him.
Claire Berger is a French physicist at the Georgia Institute of Technology and the Director of Research at the French National Centre for Scientific Research.
 Berger has co-authored about 200 publications in international journals and has a citation index of 10,880.
 She has won a number of prizes including the CNRS medal for Young Researcher and the Ancel prize of the French Physical Society.
 She was recently elected fellow of the American Physical Society.
The Savart wheel is an acoustical device named after the French physicist Félix Savart (1791–1841), which was originally conceived and developed by the English scientist Robert Hooke (1635–1703).
Cape Mascart ( ) is a cape forming the northern extremity of Adelaide Island, Antarctica.
 It was discovered by the Third French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, and named by him for French physicist Éleuthère Mascart, director of the Bureau Central Météorologique.
