Why random walk?

I know that many of you would have got the question why I have chosen 'Random walk' as the title for my blog. Only once I was asked that question; I was thinking of writing about it for quite sometime.. Anyway, here is why my blog is named so..

* The obvious guess is, it talks about the randomness of the topics of my posts. That is the primary reason.

*In addition, there ia a strong scientific reasoning as well.. in my area of polymer science, the theory of 'random walk model' is used to calculate the average end-to-end distance/length of a long chain of polymer. In this model, the 'random walk' is taken by a 'drunkard' ;) (equivalent to an active growing polymer chain-end).

* Since it is strongly based on probability, the 'next move' in a random walk is totally unpredictable, and no direction gets a preference over the other. I try to do the same by not writing on the same topic for 2-3 consecutive posts.

* Wiki cites some interesting applications of the theory of 'random walk' in other areas, such as..

#In psychology, random walks explain accurately the relation between the time needed to make a decision and the probability that a certain decision will be made. (How is itt??)

# In vision science, fixational eye movements are well described by a random walk.

# Random walk is used to model gambling. (how about making some moolah, guys?)

# During World War II a random walk was used to model the distance that an escaped prisoner of war would travel in a given time. (ada paavigalaa...)
