  • Why are burgers so thick ?

  • Why are traffic so unpredictable ?
  • Why people watch mindless teleserials ?

Scratches and patterns

Posted in Science by Karthi on November 7th, 2006

If you observe a light source through glass that has lot of scratches, you can see that scratches makes a circular pattern around the light source. You move the pattern also moves. Looking out for reason.

Between tongue and teeth

Posted in Uncategorized by Karthi on October 27th, 2006

I wonder how do the tongue and teet synchronize their movements? What kind of feed back mechanism exist between them, so that teeth don’t step on the fleshy tongue ? This I am thinking after I bit my tongue Ouch…

Cultural divide

Posted in General by Karthi on September 28th, 2006

To me it is clear that there is clear cultural divide between hindi and tamil film music. It is real surprise to see no one felt the imapct of Illayaraja’s music and background score in RGV latest movie Shiva. No reviews, no promos in music channel, no mention of music and bgm by the élite reviewers either television or in newspaper.

Why is it majority of people (other than south indians) find it difficult to appreciate his music and back ground score. When songs which are at nadir gets played forever and hyped to un imaginable extent, why is no one speaking about Illayaraja’s music ?

If you have solved todays sudoko puzzle, then you can pamper your self. You have solved one of the NP class problem! All sudoku problems are of the class NP type.

 sudoki   second order sudoku

I wish to know if this thing has happend to you while solving sudoku. Have you ever breezed through one of those hard sudoku problem meanwhile got your self tied in attempting to solve those medium ones ? Want to know how news papers classify the problem as easy, medium and hard ? The ones based on the givens may be misleading. Secondly did any body use second order sudoku puzzle to derive rules ?

What is NP problem : Explanation from claymath.com 

Suppose that you are organizing housing accommodations for a group of four hundred university students. Space is limited and only one hundred of the students will receive places in the dormitory. To complicate matters, the Dean has provided you with a list of pairs of incompatible students, and requested that no pair from this list appear in your final choice. This is an example of what computer scientists call an NP-problem, since it is easy to check if a given choice of one hundred students proposed by a coworker is satisfactory (i.e., no pair taken from your coworker’s list also appears on the list from the Dean’s office), however the task of generating such a list from scratch seems to be so hard as to be completely impractical. Indeed, the total number of ways of choosing one hundred students from the four hundred applicants is greater than the number of atoms in the known universe! Thus no future civilization could ever hope to build a supercomputer capable of solving the problem by brute force; that is, by checking every possible combination of 100 students. However, this apparent difficulty may only reflect the lack of ingenuity of your programmer. In fact, one of the outstanding problems in computer science is determining whether questions exist whose answer can be quickly checked, but which require an impossibly long time to solve by any direct procedure. Problems like the one listed above certainly seem to be of this kind, but so far no one has managed to prove that any of them really are so hard as they appear, i.e., that there really is no feasible way to generate an answer with the help of a computer. Stephen Cook and Leonid Levin formulated the P (i.e., easy to find) versus NP (i.e., easy to check) problem independently in 1971.

Flickr contacts and Blogroll

Posted in Uncategorized by Karthi on September 5th, 2006

I had asked this question in one of my previous posts.

The reason that I think of the one that is responsible for having more flickr contacts than blogroll entries is that of useablility. To me it seems people find it difficult to add a new blogroll entry than adding a new flickr contact. Now I am assuming there as many interesting and good flickr pages as compared to blogs just avoid the topic of quality of the content. I may be wrong here. Finally it is interesting to note here that I started to blog so that I can improve my very bad English. I am yet to feel the improvement  :-)

Note that the flickr contact list is self contained in the flickr and there is no need to do more work to add contacts except to click a link. But for blogroll at least in wordpress one has to enter the url and description in admin mode. Blogger one need to edit the html :-(

It turns out that I have huge entries of url (both blog and non-blog links) in my favorites than in blogroll since it is easy to add the url as favorite. I do frequent these sites regularly.

Now here is one of my original idea! If we get all the favorite links from the browser into the blog then I think we will have more links just like flickr contacts. All that is required is one api to get all those fav links, I am dumb at web programming so I can ask this stupid question. Can AJAX do it?
