 Museums, a repository of great ideas March 12, 2017Visvesvaraya Industrial and technology museum in Bangalore, India is an amazing place. Takes you back in time to engineering marvels of the 20th century. Also more importantly one can see the connect between ideas and the inventions that came out. The layout and design of the museum is beauty enough to visit it once, even […]Sunny
 Engineer’s design dilemma September 25, 2016It’s been almost a week of work at the workshop and the metal structures are finally taking shape. Along the way, I had spent many hours consulting with experienced mechanical engineers on whether the structure would hold the weight I wanted them to. It was mindboggling the amount of data they had on their fingertips. In addition […]Sunny
 Scams throughout India a threat to Modi’s ‘ease of business’ policy May 30, 2016I had just finished registration of my company a few days back. Normally company registration in India is done in 3 steps: 1. Digital signature verification 2. Director Identification Number 3. VAT registration Thanks to steps taken by the central government, now registration of a startup/company has become digital. This is a big shift from […]Sunny
 Strain energy, shape functions, minimum potential energy principle September 14, 2015New blog post: Relating the minimum potential energy principle to FEM. Why systems of nature assume states with the lowest energies is a question that even automotive engineers have to contemplate with. The minimum potential energy principle is used in Finite Element structural Analysis. Read on further to learn about shape functions and the basic […]Sunny
 Strain energy, shape functions, minimum potential energy principle September 7, 2015Why systems of nature assume states with the lowest energies is a question that even automotive engineers have to contemplate with. The minimum potential energy principle is used in Finite Element structural Analysis. Pierre de Fermat’s leasttime principle for light states that light will travel through an optical system in such a way as to pass from […] […]Sunny

 Second order DEs in vehicle crash analysis August 11, 2015The following excerpt I take from the impeccably written book ‘Differential Equations with applications and written notes’ by George F.Simmons. ‘The use of complex numbers in the mathematics of electric circuit problems was pioneered by the mathematician, inventor and electrical engineer Steinmetz. He was employed by General Electric Company and quickly beca […]Sunny
 PoPP3 Pythagoras theorem [Ved1] June 4, 2015For Ved. Hallo! Time for some math. Fundamentals of mathematics are very interesting. This is because of the way these ideas came to life. Take for example the ‘Pythagoras theorem’. When you look at it at first glance, you see only a formula. A formula made up of letters with the number 2 on top […]Sunny
