Ramanujan Summation

Strange Ramanujan Summation 1 + 2 + 3 + 4 +… … … = -1/12

Strange Ramanujan Summation  1 + 2 + 3 + 4 +….. =  -1/12  #Ramanujan #SrinivasaRamanujan #RamanujanSummation #GrandiSeries In this video lecture we will discuss the proof of Ramanujan summation of natural numbers  1+2+3+4…..=-1/12. Ramanujan wrote a letter to Cambridge mathematician G.H Hardy and in the 11 page letter there were a number of interesting results …

Special Relativity | Lecture 18 | Maxwell Equations and Special Relativity

Special Relativity | Lecture 18 | Maxwell Equations and Special Relativity #SpecialRelativity #MaxwellEquations In this video lecture Maxwell equations are discussed. How we can get electromagnetic wave equations from maxwell equations. The video starts with time dilation and the requirement of relativity to satisfy maxwell equations. we will write Maxwell equations in both integal and …

Lecture 4-LASER Basic concept Properties

Lecture 4-LASER Basic concept Properties Lasers are special and different from other light sources due to coherence. Laser beams can be focused to very tiny spots. That’s why the laser gun is important. They can have very low divergence in order to concentrate their power at a great distance. Laser means light amplification by stimulated …
