Today is Marie Curie's 144th birthday. Tim and N. loved reading Madame Curie, Eve Curie's biography of her mother together last spring! We recommend this book enthusiastically. N. was utterly absorbed by the story of Marie's childhood, her long years of hard work with Pierre isolating radium, and her navigation of the male scientific world. Tim and N. will mark her birthday by doing a science experiment this afternoon, and recalling their favorite parts of her life story.
