A place for things

Would it not be wonderful, if I could remember everything worth remembering? Well, right now I need a place for all the wonderful thing I keep stumbling upon over a day, so that years down the line I could retrace my path.

A sense of disproportion

"His name was Ulioperistybier and he had metallic wires coming out of his skull, black and thin like well-oiled hair. Sometimes when he thought hard, his wires would sway a little giving the impression of ripples in a paddy field."

And that story would go through a needle and come out of a haystack and yet all of it would sound real as Soumojit Mistry would tell it to the young wards with so much eyebrow-dancing, chest-thumping and ocassional jumping over tables with various guttural sounds that it created a dreamy verisimilitude.

He was an accountant in a glass factory and retired sometime back. Now he just comes to our school and tells his stories. Allow me some imagination and I would say he looked like an amused turtle sticking his head out of a shell or more like a bald baby in a cradle fascinated by the jhumka hanging overhead.

'Dada, what silly stories you tell these children? Why don't you tell them something useful like freedom fighters, or Ashoka or something?'

The science teacher clearly didn't appreciate what Soumojit Mistry was doing. In fact she was worried at times over some of the things Soumojit Mistry had said in the class: 'You see, you throw an electron at the wall like a cricket ball and wait for it to rebound so that you can catch it'. Even some parents had started flocking me to express concerns about this old man telling stories.

Once we were watching the children play. Soumojit mistry pointed at a boy and said: 'You see that thin boy, if he runs any more, he would vanish into thin air'. The boy's parents moved and he went to another school in another city. Soumojit Mistry later said to me: 'See I told you he would vanish'.

I once said to him: 'Dada, you are so young!'. I wouldn't imagine an old man getting excited about a new day, every time the same sun rose in the same east! It seemed there was no worries or end to anything. Soumojit Mistry died some days later. Natural aging. I had really hoped for a more dramatic climax to the story of the man behind these many stories.

I couldn't help remembering the story I once read when I was a boy. A man in China didn't want people to weep at his funeral. So he hid lots of crackers under his garment before dying. And when the villagers set his body afire, rockets vroom-ed out to the sky and exploded and the children started laughing in joy!

What words do to me every week?


I never meant to cause you trouble,
And I never meant to do you wrong,
And I, well, if I ever caused you trouble,
Oh, no, I never meant to do you harm.

-Untitled-

It isn't about fertilizers or seeds or bees,
But I can't tend to the few ailing plants 

    and shrubs in your otherwise splendid garden.
I hope you understand and I can't explain if you don't:
I can't be your gardener.

Diary

The agenda for today is to read as much as possible from the following:
1. Message passing inference with Chemical Reaction Networks
2. Algebraic Statistics for Computational Biology
3. Lectures on Algebraic Statistics

The milestones are in answering:
1. How to do things with Chemical Reaction Networks?
2. In particular how to do Statistical Inference with CRN?

The problem is best posed as:
How to do everything in Ch-1 of ASCB using CRN?

Other things in the buffet are:
1. This pdf
2. This stackexchange thread

What words do to me every week?

But I would rather be horizontal.
I am not a tree with my root in the soil
Sucking up minerals and motherly love
So that each March I may gleam into leaf,
Nor am I the beauty of a garden bed
Attracting my share of Ahs and spectacularly painted,
Unknowing I must soon unpetal.
Compared with me, a tree is immortal
And a flower-head not tall, but more startling,
And I want the one's longevity and the other's daring.

Tonight, in the infinitesimal light of the stars,
The trees and the flowers have been strewing their cool odors.
I walk among them, but none of them are noticing.
Sometimes I think that when I am sleeping
I must most perfectly resemble them --
Thoughts gone dim.
It is more natural to me, lying down.
Then the sky and I are in open conversation,
And I shall be useful when I lie down finally:
Then the trees may touch me for once, and the flowers have time for me.
 -I am Vertical, Sylvia Plath


In spite of it's odd ways of putting things, the intended meaning is clear. You can not miss that sudden feeling of awareness at your toes, of your own uprightness. And then the thought of becoming supine would send an eerie chill up your spine. The things that Sylvia says she is not, leaves you with a sense of slow engulfing gloom, of a desire to wilt without any resistance. It is a very depressing poem. And it is beautiful in it's acute depiction of that state.
But I would rather be horizontal.
I am not a tree with my root in the soil
Sucking up minerals and motherly love
So that each March I may gleam into leaf,
Nor am I the beauty of a garden bed
Attracting my share of Ahs and spectacularly painted,
Unknowing I must soon unpetal.
Compared with me, a tree is immortal
And a flower-head not tall, but more startling,
And I want the one's longevity and the other's daring.

Tonight, in the infinitesimal light of the stars,
The trees and the flowers have been strewing their cool odors.
I walk among them, but none of them are noticing.
Sometimes I think that when I am sleeping
I must most perfectly resemble them --
Thoughts gone dim.
It is more natural to me, lying down.
Then the sky and I are in open conversation,
And I shall be useful when I lie down finally:
Then the trees may touch me for once, and the flowers have time for me.

Abilities

May be I am a not a bird but a meerkat,
so what -
I will still run from ridge to ridge
To try and see farther than anyone else.

This week on arXiv

I estimate that around 300 papers are being submitted on arXiv daily. Needless to say, one can't read them all. So I have decided to put up a shortlist of interesting papers every week. If you wish, you may think of them as recommendations. These are some other (very popular) lists of arXiv articles: this and this. However I don't find my interests very well represented there and so I have decided to make my own list.

Statistics for this week:
1. Physics ~ 1000 papers (excluding experimental papers)
2. Mathematics ~ 650 papers
3. Computer Science ~300 papers
4. Others ~ 150 papers

And the papers this week that I found to be of interest are:

Quantum Physics:
+ Landauer's principle in multipartite open quantum system dynamics
(Notes: What is collision dynamics, bipartite system, multipartite system? What is the single most new idea in this paper?)
+ The Evolution of Network Entropy in Classical and Quantum Consensus Dynamics
(Notes: Important)
+ Network coding for distributed quantum computation over cluster and butterfly networks
(Notes: Very much in the spirit of the string diagrams and network theories I have been recently introduced to.)
+ Equilibration, thermalisation, and the emergence of statistical mechanics in closed quantum systems
(Notes: The title - it better be useful)
+ Hovering over a black hole: Entangled fermions in accelerated motion
(Notes: I don't know - the picture where the regions are said to be causally independent and the general feel of the paper seemed interesting)
+ The holographic quantum
(Notes: Completely new but the abstract made me curious.)

Miscellaneous things that seemed interesting:
1. Cold atoms, Magnetic Cantilever, Zeeman Transitions etc. - how to actually control/ manipulate a qubit? The technological details - but this can't be a priority for a while.
2. Experimental verifications of fundamental assumptions of Quantum Physics. How large is the community? What does it feel like to be in their shoes?
3. Find out more about the authors of the papers and their institutions sometime.


I also wish to be following some other arXiv like repositories and some of them are:
1. PlosONE
2. Econophysics
3. Cogprints
I am not as familiar with these repositories as much as I am with arXiv.

Finally I would like put up a summary of papers from the above list that I read on Selected Papers.
