A Blend Of Theory And Practice

This article briefly compares what we study and what is required in industry! In a couple other articles I will try to give a few examples on how you can acquire best of both the worlds so that you have a better picture of it and try to work towards it.

What’s our education system like

Compulsory Disciplinary Courses (CDCs) are the mandatory courses that you will have to do in your 3^rd and 4^th years of engineering to get a bachelor’s degree. I was in your shoes a few years back and it’s sad but true that most of us memorize formulae and get good grades in these CDCs. Indian education system is very textbook oriented. Be it any university, we have a certain prescribed textbook and the professor teaches exactly from that textbook. If that textbook- professor combination is good, you like that subject and you explore more, otherwise you bunk classes.

Good thing about our education system is the fact that we are molded fairly strongly in the mathematical aspect of any subject. We can analyze any particular engineering system optimally in a theoretical manner. But when it comes to building that system, we lack in experience and the tools. In the west what I experienced is something different. An undergraduate student may not be very proficient in calculus or differential equations or matrices (which are basically building blocks of engineering) but when it comes to building a working prototype of any phenomenon, they have the required tools.

What’s in the western education system?

The reason behind this is the western education system for engineering. They have something called as design projects/ semester long course projects in most of the courses. These either include a part of a research problem the course instructor is working on or any relevant project that students choose. Teams of students constitute MEs, EEs and CS guys and the work is divided accordingly. Each project has biweekly/ monthly design reviews by the professor where the teams present their progress in front of the class. During every design review, the professor gives guidelines for the next few weeks. Basically students learn a theoretical concept in class and in parallel apply that concept in their design project. At the end of the semester, every team comes up with a working prototype of the theory that they learnt in the class.

My personal experience

I can give you one example of such project I was involved in. In our mechatronics course we had to design a nano-positioning system which will position a certain object in all three co-ordinates. My team constituted of one doctoral (PhD) student working in the nano-positioning research area of the course instructor, one mechanical engineer, one hardware engineer and me. The PhD student contributed in the physical design of the system, the math/ physics behind it and how to model the system on paper. I was responsible for developing a controller that would control the system. The mechanical engineer was responsible for solid modeling and machining/manufacturing the system prototype and then the hardware engineer was in charge of deploying my controller on the actual hardware and interfacing it with the sensors and actuators! ….Result: We got a cool working mechatronic system by applying all the interdisciplinary knowledge that we learnt from the course, and we as a team learnt different aspects of engineering from each other.  Here is the link of the research if you are interested.

What you can do to take the best of both worlds!

So the giveaway is: Try to explore tools and try to get hands on experience in the CDCs that you like, or that you want to do your career in. Don’t waste your spare time in fetching new reference books and solving problems behind the chapters. Spend time in learning softwares relevant to the course (it could be softwares like MATLAB/ Simulink, Octave, Solid Works/ProE,  EagleCAD, Labview etc) or programming languages like C/ C++. Try to find interested people on campus and tag along with them to build something cool. Have simple tools like soldering iron, screws, hammers, pliers/ strippers, an arduino board, some resistors, capacitors, some wires handy. Make use of your campus workshop facility. It’s exciting to try out small things that your learn in your courses, even if it’s just blinking an LED, or using a mosfet to switch high loads: that will give you immense satisfaction and enthusiasm to build more. As you dive more and more into your discipline during your engineering years, you will develop a good blend in formulating any system on paper and then building a small prototype of it!

So.. good luck! Get your hands dirty! :) ..A combination of strong mathematical background and hands on experience will do wonders when you go into the industry!
