Statistical Analysis of Data

Nowadays there are hardware and software tools to analyze the ever expanding data stream we can get. When the speeds are Terabytes per second, and the storing devices reach tens or hundreds of Terabytes, it is clear we are in the Information Era. Theoretical Physics, as a search for ever smaller representations of bigger and bigger data sets, is the correct approach for this daunting task of the XXIst century.

Following the Fit and Leibniz Principles presented in previous posts, one can expect success, at least to the level that Physics, as started by Leibniz and Newton has had.

There is a whole Quantitative Finance section of the arXiv.

Furthermore, physicists have intuition for proper physical behavior, and a mathematical language to express it.

Let the children of Leibniz, and so many other diplomats, and government advisers, bloom.

Gauge Theory and Infeld-Hull

I know the factorization method of Leopold Infeld and his student Thomas Hull (I-H). The quest for exact solutions since the time of Evariste Galois has become an industry. I am pursuing the proposal that Theoretical Physics algorithms, can be systematized by the following two principles:


  • Fit Principle (FP)
  • Leibniz Principle (LP) 
The first could also be called Gauss Principle, the first example was the Minimum Mean Square Error Fit algorithm. Leibniz advised to use the simplest algorithm to represent data. Put together they are  useful, and a guide to understand the four Forces of Nature.

I-H has an intermediary step with the first variation operator additively modified by a gauge function. This function encodes the forces.

My Children are Thinkers

I expect not to annoy readers writing about how good my kids are. It is mine and my wife's fault, which for good, or ill, they are as they are. Of course also it is their fault, that is how they were born. The point of this note, is to record an observation based on my being back in the States, and thinking about the many students I have had in the past.

These kids are good!

“¡Madre, mataron a mi amigo madre, yo lo vi cuando cayó cerca de mis pies!”. No lloró.

Mother they killed my friend, I saw him when he fell at my feet!. He didn't cry.

Mexican student shot at in a peaceful demonstration in Chilpancingo.

"Chilpancingo, 15 de diciembre. Édgar David Espíritu Olmedo, el normalista de Ayotzinapa hospitalizado en la clínica de ISSSTE de Chilpancingo por herida de bala, era el de playera roja que el día de la represión policial en la autopista del Sol, pidió auxilio a los federales tras el disparo, y se lo negaron. Esa playera, era nueva. Fue un regalo de su tía, que vive indocumentada en Estados Unidos."


Chilpancingo, December 15. Édgar David Espíritu Olmedo, the Ayotzinapa, Education School student hospitalized in the Chilpancingo State Workers Social Security (ISSSTE) clinic for bullet wound, was the one wearing a red t-shirt, who during the police repression day in the Sun Highway, asked for help to the federal police after the shooting, which was denied. The t-shirt was new. It was a gift from his aunt, who lives as an undocumented worker in the US.

I Love Leza!

Yesterday I was received in Warrenville by the warm hug of my daughter. The garage door was not working, the little one (not little anymore), stepped on top of the car, and reset the damn little computer controlling the door, and voilà, it worked!

Now, she wants her daddy to take her to the movies. :)

December 12, 2011

 I ate with Ricardo today. Almost nobody is here, today is  Our Lady of Guadalupe's  day, he is from El Ciruelar [link]. He had a test today, and didn't go with his family to the celebration. They gave us a special Banana Leaf Tamal for free, to celebrate this very special day in Mexico.He told me about his religious doubts; obviously he chose math over the Gudalupan Virgin today.

He recently wrote about the July 1, 2012 presidential election, [link]. I feel responsibility, with the rest of the faculty, for the direction these young women and men take in their future life.

I am convinced that a life with rational reflection, is worth living.

Welcome Ricardo!

Child Rearing

Today is my Wedding Anniversary.

Congratulations to us!

We were made for each other. We spent 10 years with the first little flower, and the next 10 with that beautiful boy! They even thought, he was a girl, so beautiful is he.

It did pay off to spend that lovely time with our children when they were younger.

He's so beautiful

From Obama's Speech to East Aurora High School Student

Today I was contacted through facebook by a former EAHS student of mine. He works in Lile, and is studying at Wuabonsee Community College.  I applied there last summer, and they didn't hire me after an interview. The good news is that I hadn't had an interview in a long time, the bad news is the outcome. Maybe I do not look so handsome as when I was twenty, who knows, and who cares?

After listening the great speech by the POUS, our POUS, I am inspired to try again.

How should I get back to the US?

I feel that it has to be through the private sector, but if Waubonsee, wouldn't hire me, when I am more qualified than most of their applicants, I think I should try to go through a community that sees value in my many years of study. Twenty four to be exact.

I feel that my high school students in the Chicago suburbs liked me; at least some of them, even though the hiring persons didn't like me enough.

I could leverage that fact.

Teaching Moments

I feel I have a teaching moment now. Not every minute of our lives is equal, as far as its consequences for future minutes, hours, days, years, and lifetimes, are concerned.

Finally I have an idea I can get behind. Revision of the Scientific Method, because of the digital economy we have already entered. Also kids are following me from Illinois to Guerrero. I have an audience many teachers will love to have. (Hi guys, and gals!). When I see the faces of my students I feel, their love sometimes . I cannot let them down.

The 1% has to step down!

It is wrong, that 1% own 40% of the wealth: That is WRONG.

From the link above:

a teaching moment was an unexpected and unplanned opportunity, during a planned lecture or lesson plan, to really connect and teach your students.

These two gentlemen work in Mexico City, one in the North (Bogdan), and one in the South (Alexander). Both are Eastern Europeans.

Why do not they quote each other in their papers?

Maybe, I'm making too much of this. I know Bogdan, I don't know Alexander.

Tolkien

Three Rings for the Elven-kings under the sky,
Seven for the Dwarf-lords in their halls of stone,
Nine for Mortal Men doomed to die,
One for the Dark Lord on his dark throne
In the Land of Mordor where the Shadows lie.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the Land of Mordor where the Shadows lie.



Which Way?

OK, two principles to rule them all, (Tolkien had one ring ), but now which way should I go?

I can start with simple applications, like fit $$\pi$$:

If I try a Monte Carlo program, this will take forever ...

I guess the way to go, is to look at an unsolved problem, apply the method, and solve it.

Tall call.

Eric S. Raymond

All computer gurus are named Eric.

I wonder if the Greek Logicians would object to this statement.

I had the privilege of meeting, and driving around Eric in Naperville, IL. We invited him for our Software Symposium around 2000 at Lucent. That was great. I had written to Richard Stallman, but he wouldn't talk just for room and board. Our supervisors were not going to pay ANY speaker a gratuity.

It was funny when I later learned, through my friend Enrique Zeleny, that Stallman stayed in a squatters' place in Puebla! Go figure.

The point of this note, though; is to comment on a very good book by Raymond - I  have a friend that translated another of his great books, "The Cathedral and the Bazaar" to Spanish, José Soto - the other book is "Homesteading the Noosphere."

I finished a course in Moodle here in Chilpancingo, today. I already installed it, in my Ubuntu powered desktop.

My son has been running Apache in his Apple hardware for a long time now, but this is my first server!

I can now host my own private space in Moodleland!

I can put here my Algebra class. Here is the blogspot version.

I am homesteading the Noosphere.

BTW, I finally bought Pierre Teihlard de Chardin classic book: Vision of the Past.  I found it in a used book stand in a street in Mexico City! I paid four bucks! I will finally read what was his vision of the Noosphere.

It seems that slowly, but surely, I am finding my crowd in Chilpancingo.

I cannot do PyChilpo alone.

AMLO and Obama

This is eerie.

Next year is the last one of a long Mayan count; and we have two politicians that sound like Messiahs.

Obama: "Look at the statistics. In the last few decades, the average income of the top one percent has gone up by more than 250%, to $1.2 million per year. For the top one hundredth of one percent, the average income is now $27 million per year. The typical CEO who used to earn about 30 times more than his or her workers now earns 110 times more. And yet, over the last decade, the incomes of most Americans have actually fallen by about six percent."

AMLO: "Una vez elaborada esta constitución moral, debemos hacer el compromiso de fomentar estos valores mediante todos los medios posibles. Introducir en la enseñanza la educación moral, darle toda la importancia que tienen materias como el civismo, la ética y la filosofía; propagar virtudes y destacar ejemplos positivos en los medios de comunicación. El propósito no sólo es frenar la corrupción política y moral que nos está hundiendo como sociedad y como nación, sino establecer las bases para una convivencia futura sustentada en el amor y en hacer el bien para alcanzar la verdadera felicidad."

(Get Google Translate for this)

If the world is going to end, like my buddies have been telling me since I was nineteen years old or so, I expect to see signs, like thousands of twenty somethings filling the plazas of Tunis, Cairo, Tripoli, Athens, Rome, Madrid, London, Paris, New York, and Chilpancingo.

I've seen that all.

Tighten your belts, we are heading for a wild ride; I hope we survive.

Go on kids: If you don't save your own world, you won't have kids to give the world to.

Who Has the Money, and Why?

With all this talk of the 99% and so for, I've been telling my students that the 1% that has the money doesn't deserve it.

Here I'll try to come to terms with this notion.

Who deserves what, and why?

I got a little inheritance from my mother. She got it from hers, who after becoming a widow married an older man of comfortable means.

In what sense do I "deserve" the money?

I was given a good hand, compared to most Mexicans.

I even got a scholarship, with  Mexican tax money, to work on my Ph.D. degree, at the Physics Department of UCSB.

I have a better education level than most Mexicans. Do I deserve that?

Somehow these questions are sounding hollower, and hollower; at least coming from me.

I just saw Paul Krugman in a Q&A session with NYT readers, together with Joe Nocera, Carmen Reinhart, and Tom Friedman. Paul is smart, but nothing he said will take us out, right now, from the mess we inherited.

Does Carlos Slim Helú deserves to be the richest man on Earth?

I guess I am not going very far with this line of questioning. Say; I prove a Theorem that Carlos Slim money should come to me on the basis of me having a graduate degree from UCSB, and he only a Civil Engineering one from UNAM.

Who will give me that money after I prove the Theorem?

Hogwash, Stuff and Nonsense.  If Paul Krugman, and me are smart. We each have to change the world, more than we have so far.

I am in a nasty mood right now. My family doesn't have the money we need. Even worse, no Nobel Prize quality work coming from this head, and this keyboard, anytime soon. At least Paul already has his!

Oh well.

Carlos Slim has the money, for no good reason I can understand. I have my hypothesis ... here we go again.

Is the Moon There When we are not Looking?

"Strictly speaking what we proved is that the question of context in the macroscopic world is an ill-posed one because of the limited class of feasible measurements one can perform. The smaller set of measurements leads to a simplification of quantum theory that removes certain non-intuitive features such as contextuality while still preserving other features such as entanglement [10, 11]. Similar phenomena were observed in a toy model of quantum theory proposed in [12]. An interesting open question is to investigate the complexity of measurements needed for contextuality to emerge." arXiv

Can't Keep Johnny Down

Do I Understand?

I was baffled in the early 2000s, when first I lost my job at Lucent, and then the rich "smart" investors of DuPage County were building houses that nobody could buy!

What am I missing?

Now I see that the US is woefully behind China, NYT, and the US is going through a financial mess, to put it bluntly. It is called Real State Bubble.

Yes I was right!

I do understand.

What is coming? First those Bozos running for the GOP Presidential Nomination, all have to collapse like the Big Balls of Hot Air, that they are. Then more and more centrist rational American BUSINESSMEN, have to take control. Let us end these nonsense.

The US has to get back in track.

We can do it, guys. Wake Up.

Leza Natalia Cantoral Bronstein

My daughter found out that we were going to name her Natalia, because of my Great Grandmother, but we named her Leza, after my wife's Grandmother. She liked Natalia, and told the administration in High School to write in her Diploma: Leza Natalia Cantoral.

She has chutzpah!

Stock Market?

I have a friend from Lucent. He studied Physics at the University of  Colorado. Now he is working for the financial sector in Chicago. If I am right, and all Theoretical Physics is sophisticated curve fitting, I wonder if I can just as well fit financial behavior?

I'm reading an econometrics paper in arXiv. I was inspired by this year's Economics Nobel Prize in Cause and Effect in Macroeconomics. NYT.

I was biased against finances, I thought there was no way to guess right.

Now I wonder.

BTW, I'm studying R.

Sad

My Me'phaa student is getting checked next week for Cancer. I was reading Nicholas Kristof piece on the NYT today.

Give to underprivileged people of the world.

All I can do is teach her.  I have the ugly feeling that Mexican Indians have more deceases than the rest of us.

“life breaks us all but in the end we are stronger in the broken places”

Ernest Hemingway 


Today I am supposed to be downtown Chilpancingo breaking a Guinness World Record. "Mexico Seeks New Guinness Record For Moon-Gazing With Telescopes".

I won't go.

Many years ago, I was 19 or 20, I don't remember, I found myself reading USSR propaganda; I completely forgot I had to be in soccer training. I played at a UNAM's junior team. UNAM soccer is strong, they've been champions of the Mexican Professional Soccer League; here is the Wikipedia link: Pumas.

Another break in my life path, another fork in the road, happened in 1998; when I left BUAP, to join Alcatel-Lucent.

Today I change path direction again. Following Roberto Bolaño, Abandon Everything, Again.

My acclimation period in Chilpancingo is over. I have to keep working on my PyChilpo project. 

Classes Over!

For all practical purposes I am thinking of the next term rather than the present one. One of my Simulation class  students  [link], is not coming next week, they are 2 only. Then I leave to Chicago, December 15. I have a Physics class that is used basically to teach my stuff of a New Scientific Method [link], then I have an "Analysis of the Contemporary World" class [link]. That's it!

These are the sunrise and sunset times, that day in Chicago.

So starting today, I am working on my stuff, even during my days in Warrenville.

I am reading Bill Byers' "How Mathematicians Think" [link].

The aha moment is crucial. Professor Wiles had it to solve Fermat's Conjecture in 1993, [link]. I cannot pinpoint a year, but I can put it around the past six months. Definitely Professor Fivel's post in the arXiv was crucial, [link].

I grant that it is not a discovery of: How is the Universe?, but rather of: How is it that we know it? But in any case, I am hopeful that something will come of it. On the other hand I do not have too much time left "Waiting for Godot", [link].

There are not mathematical equations or programs "up there" waiting for us to go fetch them. We have to make them, and the sooner I start, the better.

For starters I have two principles. The Principle of Fit (PF), and the Principle of Leibniz (PL). The first I have already described in this blog, we sort out all programs and equations, until we find the best fit to data, the second is described by Gregory Chaitin, [link], i.e., another requirement by the New Kind of Science here advocated, similar to Wolfram's [link], is that it has to be the shortest program.

From these humble beginnings, I hope to build a Numerical Computation Platform [link].
