The Author Of This Site Is Me -- Kaustubhan Srivathsan. I Am A Mechanical Engineer (nit Surathkal) And An Mba From Iim Calcutta, With More Than 30 Years Of Practical Experience In Industry, Mostly Automotive Industry. I Have Been Vice-president Of Engineering At A Top Car Manufacturer , And Chief Technology Officer In An Engines Company . I Decided To Do This Site Out Of Sheer Interest And To Help Students And Others Everywhere, And Save Their Massive Time And Effort To Get Through Physics. I Feel That Most Topics Can Be Explained In Videos Of 6 Minutes Flat . A Student Who Understands Physics Fundamentals Has A Strong Chance To Become A Great And Practical Engineer.
