Electronics vs.Electrical !!

Well .. this topic might seem dated, it would have been fit for my engineering days, nevertheless the myth that I intend to clear is important for everyone in general . . . . Moreover I, being as passionate about electronics engineering as about management, couldn’t avoid writing about it after being instigated.
I was instigated when an electronics engineer herself said that electronics engineering has evolved from electrical engineering and the only basic branches of engineering are Mechanical, Civil and Electrical. To demystify this let me recount the history of engineering . .am sure hardly anybody has bothered to do that, but nevertheless its an interesting one to go through. . .
As most engineers are aware of, engineering is the successor of classical physics. It emerged from the field of Applied Physics, and even today both these fields run parallel; applied physicists discover principles and engineer apply them. Engineering initially started with civil engineering, then with the development of the steam engine (late 18th century) came ‘mechanical’ engineering. It was after the development of the steam ‘engine’ that the terms engine-er and engineering were coined. Later even construction specialists came to be known as Civil engineers.

It took almost a century for the next field to come up. Though electricity was discovered by Benjamin Franklin as early as 1752, it was hardly of any use. The application of electricity could find an opening only after Michael Faraday discovered electromagnetism in mid 19th century. It took another 40 years for the first electrical engineers (Thomas Edison) to come up with a working generator. This was the beginning of electrical engineering which today comprises of activities of electricity generation, transmission and transformation. (PS: Transformation means using electricity to run machines etc – transform electrical energy to mechanical, chemical energy etc)

While on one hand electrical engineers were busy with alternating current, at the same time some physicists were trying to understand the very electron which produced it; and they stumbled upon the Vacuum Tube - the first electronic device. It was now that the history of electronics began to evolve.
And now to put the records straight electronics was developed from concept of electron and flow of charge (which is not the same as flow of electricity) rather than the electromagnetic induction. Electronics has nothing to do with Faraday’s laws whatsoever, while the same laws form the very basic of electrical engineering.
In fact the most important difference between the fields of electrical and electronics is that electrical deals with alternating currents where as electronics with direct current. Electrical engineers are concerned with transformation of power; they operate in the scale of Volts and KVolts. Electronics engineers are concerned with the control of flow of charge and not power; the operation is in the range of microamperes(μA) and millivolts(mV). And so principaly electronics engineering has evolved directly from physics like all other 'basic' fields, validating the fact that eletronics too like mechanical, civil and electrical is a basic field of engineering . . .
Well.. believe that’s quite a lot . . . If I say more the facts might loose their effect. . . I hope the myth is cleared . . . all doubts and counterclaims are welcome . . . do feel free to comment ;))

How will travel industry transform post-Covid

Unlike philosophers, journalists and teenagers, the world of entrepreneurship does not permit the luxury of gazing into a crystal ball to predict the future. An entrepreneur’s world is instead made of MVPs (Minimum Viable Product), A/B Tests, launching products, features or services and gauging / measuring their reception in the market to arrive at verifiable truths which can drive the business forward. Which is why I have never written about my musings or hypothesis about travel industry – we usually either seek customer feedback or launch an MVPised version and gather market feedback. However, with Covid-19 travel bans across the globe, the industry is currently stuck – while a lot of industry reports and journalistic conjectures are out, there’s no definitive answer to the way forward. Besides there is no way to test your hypothesis since even the traveller does not know what they will do when skies open. So, I decided to don my blogger hat and take the luxury of crystal gazing

Experienced vs. Freshers – an MBA perspective

Shubham and me compiled and created an article during our first year of MBA. It was never published, nevertheless MBA aspirants will find it very useful. Publishing it online for the same purpose. However, Shubham and myself claim a copyright on the text .... and of course very many thanks to all our freinds whose views have helped us compile the article. Experienced vs. Freshers – an MBA perspective By Nikhil Kulkarni, KPMG Shubham Choudhury, Infosys PGDIM- X, NITIE, Mumbai Ashita Mittal was placed during her final year in engineering college with a leading software firm. But she never wanted to be another brick in the wall. She wanted to differentiate herself from other graduates who start their career at the lowest rung of organizational hierarchy. MBA was a natural choice for her. On the other side is Shailesh Dhawla, who worked as a software engineer with a leading software consultancy firm for 3 years. He started his job with some ends in mind, like working with a known c

Ekla Chalo re

Watched "Bose- The forgotten Hero" on Saturday. Gem of a movie and probably the best of Shyam Benegal. Subhash Chandra Bose has always been an inspiring character in the history for the youth. This post however is not about the movie, its about the lead song 'Tanha Rahee' which is based on the poem 'Ekla Chalo Re' by Gurudev Rabindranath Tagore. I had pasted the English translation of this poem on my blog earlier. However, yesterday I found the original bengali text of the poem and found that the meaning in the above translation was not exact. So I have endeavourer (with the help of Shubham ) to re-translate it into English and Hindi by myself. Here is the output of my work: Bengali Jodi Tor Dak Soone Keu Na Asse Tobe Ekla Chalo re Ekla Chalo Ekla Chalo Ekla Chalore Jodi Keu Katha Na Kai Ore Ore O Abhaga Jodi Sabai Thake Mukh Firae Sabai Kare Bhay Tabe Paran Khule O Tui Mukh Fute Tor Maner
