Marie Curie - Verifing From Her Hypothesis
الزمان: Thursday 14 Apr 1898
المكان: Paris, France
التفاصيل: On 14 April 1898, the Curies optimistically weighed out a 100-gram sample of pitchblende and ground it with a pestle and mortar. They did not realize at the time that what they were searching for was present in such minute quantities that they would eventually have to process tons of the ore.
