HE DIDN’T detect THAT plenty of chemical substances may supply OFF strength, AND HE DIDN’T thoroughly comprehend the place THE power used to be COMING FROM. BECQUEREL hung on TO the concept that THE power HAD whatever TO DO WITH PHOSPHORESCENCE. AFTER HIS FIRST good fortune, HENRI STOPPED EXPERIMENTING WITH URANIUM. THAT’S ONE cause MARIE CURIE made up our minds to select IT UP. * * * this present day we all know that uranium is one of many metals that supply off strong radioactive rays. but if Marie Curie begun her learn, the observe radioactive didn’t even exist! nobody knew why uranium gave off strength or why it may make issues glow in the dead of night. not anyone knew then that uranium can be used to make a bomb or a nuclear strength plant.
