Silicon changed life-style on this planet

We all read in our high-school social studies subject that industrial revolution that took place in Great Britain had a big impact on social life of man on this planet. Similarly another breakthrough occurred with the advent and emergence of semiconductors, especially silicon during 20th century. TV, mobile telephony, smart phones, Video, e-books, computers, internet etc have made a huge impact on the way we communicate with the world.


All this began with the first transistor that was invented by John Bardeen and Walter Brattain while working in Bell Laboratories. They were working with the semiconductor, silicon, to evaluate its properties. When they observed that controlling the current on  the  ‘base’  connector,  would  control  the  flow  of  electrons  between  the  other connectors, emitter  and  collector. This had a great impact on electronics, leading to more reliable transistor to replace the vacuum tube. This resulted in progeny of a number of ‘transistorized’ products.

Today, we have 64 bit microprocessors of which each one has 55000000 transistors performing millions of computing tasks each second.
