## Kevin and Donna's Earthstar

08 Jul 2015 16:55
In further downsizing and simplifying their lives, Kevin and Donna have requested that their EarthStar website be removed from the internet. They remain very grateful to those who for so many years have shared their continued interest in creative simplicity. Kevin and Donna are great source of inspiration. I read and re read those words and books many times. I seems like they have decided to go...

## stillness

30 Apr 2015 18:27
Pre S: Its better to ignore the links when you read this for the first time. You can follow then later. It has been close to two weeks, since I have quit my job. I have been busy preparing for a new one. This is the mundane part of it. Otherwise, I am experiencing a subtle feeling of 'solitude'. The immediate pleasures(relaxations?) were easy to find. I do not need to commute 20km in the morning...

## Farmer and the mountain

19 Aug 2014 10:34
He sees the peak everyday, he still ploughs his land, when he feels the cool breeze, he knows its coming from the mountain when he sweats, he knows it cool up the mountain when he is having a calm meal, he can see the thunderstorms up he mountain its the time, mundane grips him no more, clouds up the mountain call him, every grass tells a story who knows what it is, home of the wild joy, when the...

## Three proofs of Erdos-Szekeres lemma

07 Apr 2014 19:10
Erdos-Szekeres lemma: A sequence of $n^2+1$ real numbers contains a monotonic subsequence of length $n+1$. First Proof. (direct argument) Let the sequence be $\langle x_1,x_2,\dots,x_{n^2+1}\rangle$. We associate an ordered pair $(a_i,b_i)$ for each $1\le i\le n^2+1$ such that $a_i$ is the length of the longest monotonically increasing sequence ending at $x_i$ and $b_i$ is the length of the...

## A review of ‘Highway’

22 Feb 2014 15:26
Imtiaz Ali, the next Mani Rathnam of Indian Cinema : A review of ‘Highway’ (No spoiler, read) Aspirations, emotions, landscape, real people, intensity all these put together to form a scintillating vivid piece of art. Its not Mani Rathnam, but Imtiaz Ali. This is possibly his best movie (as of now), sign of coming of age, although the signs of it were seen in ‘Rockstar’. The movie leans towards...

## Writing math

20 Feb 2014 17:01
Writing and conveying mathematics is an art. I have been inspired by remarkable writers and teachers (first column) and I have learn how not to write or teach from others (second column), although they could be wonderful mathematicians. This list keeps changing. David Bachman Serge Lang Steven Krantz Michael Artin George Simmons Kumaresan S Brualdi Bela Bollobas Charles Chapman Pugh...

## annotation in djvu

18 Jan 2014 09:55
An annotation is a new layer introduced by the reader for reading comfort and note making. The usual annotation facilities are 'adding a comment','highlighting a selected part of the text' and ‘rectangle tool’. As annotation standards were being established, the annotation file was kept as a separate markup file. As they became more standardized, they were integrated as a part of the document. As...

## Science after 12th

15 Dec 2013 07:07
Some questions that kept springing up during my talk with 11/12th students (pre-university or plus two students) were: . How is life pursuing science? What study opportunities do we have in mathematics/sciences after 12th standard? Where to study mathematics/sciences and what entrance exams should we write? Should I do pure sciences or engineering/medical or some other course? Will I get a good...

## Faint Rainbow

15 Mar 2013 14:41
Akash was surprised, then he was baffled, further he was amused, suddenly be became serious. Vikas although being three years younger to him, was more of a same aged friend. Other kids of Vikas's age would have had a fearful reverence towards the highschool cricket captain. Indeed it was Akash who was a secret admirer of Vikas. Did Vikas ever recognise it? nor did it seem so to Akash. When Akash...

Well, if do not already know about Alexeev's gmailtex (http://alexeev.org/gmailtex.html ), you may like to read about it before you go further. I like gmailtex.

Let there be n points on a plane such that with respect to any point, other points lie at different distances from it ( with respect to say$p_1$if distance$(p_1,p_j)$=distance$(p_1,p_l)$, then$j=l$). For every point, we draw a straight line segment that connects the point to its nearest point. Prove that no two line segments intersect.(except at their endpoints, perhaps) See the...

## Convexhull

29 Aug 2012 10:54
It is well known that for every finite set of points on a plane, there exists a minimal convex polygon such that it encompass all the points (by encompass, we allow the possibility of points being vertices and on the edges of the polygon), such a polygon is called the convex hull . Given the co ordinates of a set of points, there are several algorithms to obtain the hull (by hull, I mean a subset...

## Everything, gnu Find and Catfish

05 Aug 2012 10:38
Using everything on windows makes me efficient. It searches things in a jiffy and does not affect my thought flow. Until recently, I had this problem of finding such tool in linux. There are two kinds of indexers, one which just indexes the document metadata and other other which indexes the content of the document (processor intensive). For the latter, one would require libraries that can handle...
