Engineering... as it interests me

 I plan to write this as an professional engineer, I hold reverence to this profession retro stereotyping engineering as a boring passion to pursue, seems a little alien to me. A handful of people in engineering profession (Most probably from UG Universities) can be heard iterating engineering is boring many a times. However strange the phrase may be, yet from experience I can comfortably state that the practicing engineering is quite unlike studying engineering. The downside is a possibility of people being engaged in a monotony in career yet again.


Let me get this with a simple explanation from my experience. Pupil in engineering when their curriculum requires a project to be done tend to look on YouTube for DIY ideas. One of the popular choice of such project is an solenoid engine ( For Mechanical Engg.) which seems fairly simple. A magnet, a metal rod a little copper wire, some plastic extravaganza and a whole lot of patience and there you go.. You follow the steps stated in the video and at the end when you plugin the power supply as directed by curator, suddenly nothing works even though you have perfectly executed the steps dictated to you point to point by the curator. Many people I've come across will resort to screaming and utterly disappointed about the only unknown draw back in an otherwise a perfectly flawless plan.
      Engineering to me is a preparation for a lifetime for dealing several projects and counteract on problems that may seem how unlikely they are to happen. To follow the steps dictated in a perfectly setup well edited video you could be anywhere from a high school graduate to a drop out with a sufficient language skills. Engineering is creating those instructions in the first place. Engineering begins to challenge you when you try to ponder it. When you question it, you get face palmed by yet more questions and you try to find or create answer for every question. That's when engineering really starts to make sense. 

Lets take the same solenoid principle. To start with a solenoid is just a reverse of LVDT. In LVDT if you apply force on a conductive core placed in charged coil displacing it in the field of the coil, you'll get voltage. In solenoid, a voltage is applied across the coil, the core starts to move. Simple universal law: Energy can neither be created nor be destroyed but can be transformed from one form to another. However, in solenoid engine you need to have completely reversing voltage circuit to achieve a continuous motion or you can place two solenoids and let them on and off at 0 degrees and 180 degrees shift whichever may seem easy. Moreover this also significantly may be affected by the coil winding pitch and voltage. Solenoids are no easy cup cakes. They are carefully engineered and this analogy strikes you when you begin questioning the problem, not bragging about how it failed.
Engineers therefore must understand the fundamental physical laws which affect the structure and function of anything they might deal with. Practical knowledge is of course essential, but that comes with experience. They then learn more practical things from experienced engineers, as well as from suppliers of components and materials.
No matter what the problem to be solved, the fundamental physics are always the same and need to
be understood and applied. Some engineering jobs use a lot of math to analyze a design, some use very little. But it's much harder to learn calculus and physics on the job, after you've left the educational environment.

Yes engineering education can be boring. But the fun begins when you start applying it.

REAL MEANING OF E=mC2 (PART-1)

Hydrogen Atom has less mass than combined mass of proton and electron that makes it up. YES! How can something weigh less than sum of its constituent counter parts? Well the answer is E=mC 2 E=mC 2 is one of the most colossal equations of physics. But at the outset, in the paper published by Einstein in 1905, this equation is written slightly different. I.e.,    m= E/C 2 Because the bottom line is that this equation is basically a lesson in the corner of physics that helps us to understand and think, what mass actually is?..... You often come across the statements like Mass is a form of energy??? Mass is frozen energy??? (Seriously?) Mass can be converted in to energy??? (Worst one!)                  None of the above statements is correct.                 These doesn’t make any sense and frustrating as well.   We ...

Artificial Intelligence- As I know it

AI- The artificial Intelligence as we call it, is not a technology which has seen an easy way through the science field. Since its birth in a workshop at Dartmouth College by a group of 5 young scientists, AI made the spectators drop their jaws. It was learning the strategies of checkers and solving most complex problems in lightening speeds. Who knew by just changing 0 and 1 and their positions, we could make almost all the tasks done by computer. The ups and downs of AI has been numerous and it was again a centre for exploration ever since google started using it in its packages from 2015. So, what is the bottom line of AI in its basic sense actually?.. Computer science defines it as a device which perceives its environment and executes tasks that maximizes the successful results it is being employed for. Yeah, in its basic sense or more or less what it does, It is true indeed. Personally,  I use the Artificial Neural Network (the other name of AI) to recognise an stoc...

Springiness of Solids or The History of Elasticity

Disclaimer: This article is written keeping general readers in view and hence the usage of mathematical equations was strictly avoided. However, hyperlinks are provided for further reading. Let us twitch with an interrogation “Why any inanimate solid, for that occasion any material is capable of carrying load?”             The answer lies at the root of the whole study of structures and the intelligentsia behind this is quite complex. If there is anyone whom the credit shall be due is Sir Robert Hooke . Sir Robert Hooke Courtesy: Wikipedia             Hooke realized that materials can carry load by only pushing back at it with an equal and opposite force. This is an implicit equivalence of Newton’s Third Law .             To put this up rhetorically, a force just cannot get away. In any ci...
