Born in Warsaw, Poland, on November 7, 1867, Marie Curie was forbidden to attend the male-only University of Warsaw, so she enrolled at the Sorbonne in Paris to study physics and mathematics. There she met a professor named Pierre Curie, and the two soon married, forming one of the most famous scientific partnerships in history. Together they discovered two elements and won a Nobel Prize in 1903. (Later Marie won another Nobel award for chemistry in 1911.) She died in Savoy, France, on July 4, 1934, a victim of many years of exposure to toxic radiation.

Atrapante de principio a fin. Lleno de enseñanzas y reflexiones tan actuales como en el momento en que fue escrito (entre el 12 de junio de 1942 y el 1 de agosto de 1944).

Both struggling readers and those looking for review can find the most important components and vocabulary of the carbon cycle in low-level, accessible text.
