Not counting well-known women science Nobelists like Marie Curie or individuals such as Jane Goodall, Rosalind Franklin, and Rachel Carson, whose names appear in textbooks and, from time to time, even in the popular media, how many prominent or pioneering women scientists can you name? If any of the 10 women listed here sound familiar, we’re impressed. (And if names like Carson and Franklin don’t ring a bell, we recommend reading Britannica’s entry Women in Science).

Matter is a lush tapestry, woven from a complex assortment of threads. Diverse subatomic particles weave together to fabricate the universe we inhabit. But a century ago, people believed that matter was so simple that it could be constructed with just two types of subatomic fibers electrons and protons. That vision of matter was a no-nonsense plaid instead of an ornate brocade.
Physicists of the 1920s thought they had a solid grasp on what made up matter. They knew that atoms contained electrons surrounding a positively charged nucleus. And they knew that each nucleus contained a number of protons, positively charged particles identified in 1919. Combinations of those two particles made up all of the matter in the universe, it was thought. That went for everything that ever was or might be, across the vast, unexplored cosmos and at home on Earth.

A series of experiments at the ALTO particle accelerator facility in Orsay, France, has revealed that the fragments resulting from nuclear fission obtain their intrinsic angular momentum (or spin) after fission, not before, as is widely assumed. This result was made possible by the ‘nu-ball’ collaboration, an international group of nuclear physicists from 37 institutes and 16 countries – among them scientists from TU Darmstadt’s Institute of Nuclear Physics – which studied a wide range of nuclei and their structure. The collaboration is led by the Irène-Joliot-Curie Laboratory in Orsay.
Open questions since the 1930s
Nuclear fission, in which a heavy nucleus splits in two and releases energy, was already discovered at the end of the 1930s by the chemists Otto Hahn and Fritz Strassmann, and interpreted correctly by the physicists Lise Meitner and Otto Frisch.
