Science makes people reach selflessly for truth and objectivity; it teaches people to accept reality, with wonder and admiration, not to mention the deep awe and joy that the natural order of things brings to the true scientist. Lise Meitner Esta entrada está dedicada a una mujer singular, que no es matemática pero que usó las matemáticas en su trabajo, Lise Meitner. Merece sin duda nuestro homenaje, porque sus importantes aportaciones permitieron explicar el fenómeno de la fisión nuclear. Estos resultados la hicieron merecedora al premio Nobel de Física pero la barrera de género impidió que se le otorgara el…http://www.madrimasd.org/blogs/matematicas/files/2016/10/Lise_Meitner12-192x300.jpg
