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.
The greatest truth is honesty and the greatest falsehood is dishonesty
Everyone sees what you appear to be, few experience what you really are
I never had a policy; I have just tried to do my very best each and every day
Even if you are on the right track, you’ll get run over if you just sit there
Never, never, never give up
Life is and will ever remain an equation incapable of solution, but it contains certain known factors
