Women Role Models in STEM

Only 20% of bachelor degree in STEM are held by women. Why aren't women entering the science fields? Some say it's because there aren't enough role models for girls. The people at OnlineUniversities.com don't believe that. They have posted a list of 25 fabulous women involved in STEM fields.

The list includes astronauts, professors, a fighter pilot, a college president, physicists, electronic game creators, a co-founder of Flickr, a co-founder of iRobot, astronomers, etc. Some of the women were familiar to me, but most were not I'm sad to say. Check out the list and see who you know. But more importantly, pass it on to girls and young women you know who might be interested in the sciences. You never know who you might inspire.

25 Female STEM Superheroes of Today

Lise Meitner - Denied the Nobel Prize

In December of 1938, Lise Meitner received a letter from colleagues in Germany explaining their latest experimental results and questioning what these results could mean. For almost 30 years Lise had worked with Otto Hahn, and later Fritz Strassman, performing experiments related to radioactivity. Although she had begun as Hahn’s assistant without pay, their relationship had evolved to the point where she was the recognized expert in matters related to physics; Hahn was a chemist.

Lise’s nephew Otto Frisch was visiting for the holidays and together they discussed the letter she received. Researchers working on radioactivity had known for some time that one element could change into another, such as radium to polonium in Marie Curie’s experiments. But recently several researchers, when bombarding uranium with neutrons, had been finding elements with smaller atomic weights, almost half the atomic weight of uranium. At the time no one believed that the nucleus of an atom could be split. Hahn and Strassman’s research repeated this result. Meitner realized that this was exactly what was happening and that the power that would result from a chain reaction would be immense. Together she and Frisch worked out the mathematics and she conveyed the information to Neils Bohr who was on his way to the United States for a conference. And the rest as they say is history.

I knew this basic scenario when I began to read about Lise Meitner, but as usual there is more to the story. Continue reading
