Time, the greatest enemy of man, is an addict who smokes the cigarette of life and uses God's soil as an ashtray.

The 'stream' we call science always flows forward; sometimes reactionary beavers block its flow, but the stream is never defeated by this; it accumulates, gathers strength; its waters get over the barrage and continue on their course. The advancement of science is the advancement of God, for science is nothing but human intelligence, and human intelligence is the most valuable treasure God has bequeathed us.

One of the most tragicomic things in life is that when a man makes an imaginary thing - such as a religion - as his own flag and carries it all his life and even dies for it! An intelligent man has only one flag: Flag of reason and science!

Every man must be like Stephen Hawking. His body is here on earth, but his mind walks in the universe!

Courage makes the things easier!

The leaves of the trees are like the thoughts of the men: Some are bright, some dark; some fresh, some rotten; some healthy, some diseased.

Fools are the gift of the God to glorify the wise!
