Certain characteristic properties of elements can be foretold from their atomic weights.
I have achieved an inner freedom.
When the elements are arranged in vertical columns according to increasing atomic weight, so that the horizontal lines contain analogous elements again according to increasing atomic weight, an arrangement results from which several general conclusions may be drawn.
There is nothing in this world that I fear to say.
No one nor anything can silence me.
Knowing how contented, free, and joyful is life in the world of science, one fervently wishes that many would enter its portals.
