A Collection of Scientific Inventions & Discoveries



Today’s world is the reaction product of human kind when they adequately admix their motivation, dedication, hard work and unremitting devotion to the things they want to see happen. Everything happened in this world is created twice. First mentally and then physically. The great souls of the past believed their lives as worth living and their beliefs helped to create the facts that we are enjoying today. Their unending discoveries and inventions bring us a valuable message:

If we just hear, we may forget,
If we get to see, we will believe,
If we really do, we will understand,
Thereby we know the price of success.
