Don't be sad about the goodbyes! Because in many farewells, better unions are hidden!

We wonder of the nature and the nature wonders of us!

Our laugh is a torment and our cry is a joy for the Satan!

If you think life is a smooth sea, you will soon be awakened from this sweet dream by the slap of a bitter wave!

Science is a seagull, it knows the sky; it is a squirrel, it knows the forest; it is a mole, it knows the underground; it is a dolphin, it knows the ocean! Science is a multi-talented creature!

If you want to reduce the rats, use the cats! If you want to reduce the fools, use the books!

The best thing you can give to a child is to create an environment where the child can develop an independent mind so that he will be the man of no one and the instrument of no system!
