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.
All our dreams can come true, if we have the courage to pursue them
We are not rich by what we possess but by what we can do without
The mountains are calling and I must go
It is a good rule after reading a new book, never to allow yourself another new one till you have read an old one in between
You can often change your circumstances by changing your attitude
There is nothing more ancient than the truth
