Qualifying vs Quantifying

In this article we look into the duality of the two words, quality and quantity. The nature around us provides a good witness to make this duality precise. All the objects in the eyes of an observer are the same in the elements of composition while they are different in their nature, form and properties. The quality of an 'Engineering' product sets a standard whereas its quantity is only and (measuring) analysis tool.

It is often retold that Quality matters more than the Quantity. The reason for such a statement is recognized to be the connection and the duality of the two terms. The process of measurement comes into play, while one quantifies, whereas qualifying would require certain inferences or analysis from the measure. Look at the question "How old are you?". When this question is asked many of us has certain inherent doubts. But one knows that age is just another number. Look at this perspective into the matter. Can you think about it from the "half filled" angle of the age being a quantity that describes your physical strength, attitude, responsibility, or the like. The point being emphasized here is that quantification only leads to a sense of comparison, while qualifying brings around a sense of positive security(which in fact is the truth).

How do you measure your food habits? Is it dependent on the quality, quantity or both? Unless a desirable quality is derived from the measure being performed the exercise of measurement seems to be fruitless. In Engineering and Scientific study this stands out to a great extent. A sense of scientific enquiry, begins from the limited nature of our measuring tools, while the ability to draw useful interpretations (if not conclusions) would extend the possibility to expand our domain of knowledge.

Math as a Language for Signal Processing

[This article has appeared in the Technical Article Board April 2016, Also appeared in annual magazine of the Electronics and Communication Engg Department : Explora 2016]

Mathematics and its applications pervades in all engineering systems. Today, an aspiring engineering student can easily get demotivated by the traditional methods of instruction adopted in many of the technical institutes. In many countries, the student community across academia are in a dilemma on their inability to see any usefulness in the rote teaching-learning mechanism happening. The rising drop out rates, lack of reflection, rising unemployable population are clear indicators on the need for a change in the learning approach. With the penetration of the internet and the immense compute power brought by the electronics, one can re-invent the  math classroom to become more engaging, practical and mastery oriented.  The advent of online classes and the flipped approach of lecturing alongside with the availability of low cost electronics can trigger a rapid change in the attitude and approach towards the subject. The objective of the article is to enlighten both teachers and learners on the novel methods that are available in absorbing mathematics rather that swallowing.
