Decigram Quotes (2 quotes)
I devoted myself especially to the purification of the radium…. It was only after treating one ton of pitchblende residues that I could get definite results. Indeed we know to-day that even in the

Meanwhile, her husband, Pierre, studied the physical properties of the rays emitted by the new substances. As translated by Charlotte and Vernon Kellogg in Marie Curie, 'Autobiographical Notes', Pierre Curie (1923), 188.
I then [in 1902] possessed one decigramme of very pure radium chloride. It had taken me almost four years to produce the kind of evidence which chemical science demands, that radium is truly a new element. … The demonstration that cost so much effort was the basis of the new science of radioactivity.
As translated by Charlotte and Vernon Kellogg in Marie Curie, 'Autobiographical Notes', Pierre Curie (1923), 188.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
