WHAT IS NANOTECHNOLOGY ?

N anotechnology is the science of manipulation of matter according to our need at the Nanoscale of the order of 10^-2 . it have tremendous possibilities in near future because of its ability of making advance material  with unique chemical property which suits according to condition   .  This term technically first time introduced by physicist Richard Feynman in 1959 in his lecture with topic of There is plenty of room at the bottom . but at that time technology was not enough to implementation of his idea in practical application's . Primarily there is two type of approaches we use to construct anything  - I)  Top-to-bottom approach  II) Bottom-to-top approach Top-to-bottom approach :- when we cutoff resource to make our desirable shape is known as Top-to-bottom approach ; Ex- wooden chair .  Bottom-to-top approach :- when we construct structure by starting from its minute cells to approaching required shape of structure is known...

BEGINNING OF THERMODYNAMICS ?

Thermodynamics is the the science of energy . in which we study about how energy could  be converted into  primary interest with high efficiency . although The first commercially-successful engine that could supply continuous power to a machine, was the atmospheric engine , invented around 1712 , but there was not proper scientific explanation which can describe how system is running and at what condition's it could get more efficiency . First scientific formulation of thermodynamic was made by a french military Engineer Sadi Carnot often described as Father of Thermodynamic . He published his work in a book  - Reflections on the Motive Power of Fire and on Machines Fitted to Develop that Power .  He was the first person talked about how steam engine's or system efficiency could be increased by increasing the temperature difference between source body and sink body .  source body - Is the body from which system takes heat as input to convert it into p...

SUM OF INFINITE SERIES BY RAMANUJAN

I n this blog i am going to discuss about something very strange important but strange a master piece from a Indian mathematician Srinivasa Ramanujan , who who discovered something mind blowing .   So if i ask you what is the sum of all natural number more likely you will answer  "infinity" and like always genius personalities has something different opinion just like srinivasa Ramanujan . Lets see how                    1+2+3+4+5+6+7+8+9 . . . . . . Became  -1/12 Let's take a infinite series S1 -                     S 1 = 1-1+1-1+1-1+1-1+1-1+1 . . . . . . lets do little maneuver with it like we always do in mathematics -  S1 = (1-1)+(1-1)+(1-1)+(1-1)+(1-1)+(1-1). . . . . .  we are just taking brackets at first on "plus one" and than closing it after...
