29/2012 Mathematical Foundations of Computer Science

Mathematical Foundations of Computer Science (MFCS) is taught in many of our institutions. It is also called as "discrete mathematics". One of the main hurdles in teaching MFCS is about deciding what exactly should be the coverage of this course. Here is an initiative by IEEE to catalogue the contents of MFCS. This effort is available for review at :

The effort is being directed by an Indian, based in India : Nabendu Chaki, University of Calcutta,

My colleague teachers, and people who plan our curricula, are invited to have a look.

27/2012 Math makes you more crazy

In my last blog post, I named one crazy area where I started working recently. I found one more area which I find fascinating:: using maths to design musical instruments. I took the humble "bamboo with a hole" instrument called flute. Here is what I found

Flute Theory and Maths

Blame it on maths, if you find me behaving crazy.


26/2012 In outer space, which side is north ?

It is amazing how much the w-w-web can distract you and entice you into random directions. I am now getting addicted to some fascinating questions about astronomy. Here is one I picked up at ::


The question I am refering to is :: Is there such a thing as “North” in outerspace?
On Earth, North is determined by the magnetic poles of our planet. Is there such a thing as "North" in outerspace? To put it another way, is there any other way for astronauts to navigate besides starcharts? For instance, if an astronauts spaceship were to be placed somewhere (outside of our solar system) in the milkyway galaxy, would there be a way for them to orient themselves?

There is still so much to discover and learn. There is so little time left.
