Sir... Please look back at History... who said hand phone could not have been introduced 30 years ago.. it was not done purposefuly... the so called CDMA technology was used in World War 2 itself... what are you talking about Science... when did electricity actually come.. 200 years ago... this world is Multi Million years old and human beings have been living for millions of years now.... All this so called science is pure crap and waste of money... across the world so much money is being wasted in this so called science which generates no direct revenue.... Look at the amount of money we waste in Defence and astronomy... Let us feed people yaar... there are so many who are dying of Hunger... let us look at ground reality rather than appreciating these so called glorified useless scientists
