Mária Telkes. New York World Telegram and the Sun Newspaper—Al Ravenna/Library of Congress, Washington, D.C. (neg. no. LC-USZ62-113268) 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 W...

5 hours ago 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 containe...

Price: 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-J...

Tacke received a bachelor’s and a doctoral degree from the Technical University in Berlin in 1919 and 1921, respectively. In 1925 she became a researcher at the Physico-Technical Research Agency in Berlin, where she began collaborating with chemists Walter Noddack and Otto Carl Berg. When Russian chemist Dmitry Mendeleyev proposed the periodic table of the chemical elements in 1871, he left gaps in places where he believed unknown elements would find their place. Two such gaps were below manganese at atomic numbers 43 and 75. Tacke, Noddack, and Berg set out to discover these two elements, ...
