The elements which are the most widely diffused have small atomic weights
Russian chemist and inventor. He formulated the Periodic Law, created a farsighted version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered.
You must keep your judgement clear of the mists of vain conceit
We don't stop playing because we grow old; we grow old because we stop playing
Don’t fall in love. Fall off a bridge, it hurts less
As a writer, you should not judge, you should understand
Measure what can be measured, and make measurable what cannot be measured
It is not enough to have a good mind; the main thing is to use it well
