Ci volaba!!!

Mira el cielo y el sol baña su rostro.

El azul magnifico combinado con el blanco de las nubes lograron estremecer sus sentidos, arrancando asi una lagrima desde lo mas profundo de su ser. Cerro los ojos, pero su cuerpo, liberado volaba... podia recorrer cada rincon del amplio universo.

Mientras mas alto el vuelo lo llevaba, sus disfraces se fueron desvaneciendo, quemando y las cenizas cayeron al suelo haciendo teblar todo lo que en el reposaba. Edificios y persona vinieron abajo, quebrantando con ello ideales y convicciones.

Subio aun mas alto, y su ser se limpio por completo. La pureza le llevo al conocimiento total, y la felicidad lo embargo.

Asi sucedio y asi se recordara.

Nel cuore lei. Andrea Bocelli.

Se
Conosci già l’amore
Che vuole lei
Tu saprai che dovrai
Dare tutto quel che hai
A lei
Ti legherai finchè vivrai, al lei….

Ti prenderà il cuore
Ti vincerà
Lei sarà la tua strada
Che non puoi lasciare mai
A lei
Ti legherai finchè vivrai, a lei….

E non c’è niente come lei
E non c’è niente da capire
E’tutta lì
La sua grandezza
In quella leggerezza
Che solo lei ti dà

Sarà così e poi
Sara di più
L’amerai….l’amerai
Perchè tu ci crederai
A lei, a lei
Ti legherai finchè vivrai, a lei….

E non c’è niente come lei
E non c’è niente da capire
Lei è così
Puoi solo dire
Che più ti fa soffrire
Più ancora l’amerai

Finchè tu vorrai scoprire
Dentro un brivido che dà
Il segreto della sua eternità

A lei
Regalerai
Quello che resterà
Del tuo tempo che verrà
A lei
Ti legherai, per sempre avrai
Nel cuore lei….

Dell'amore non si sa. Andrea Bocelli

Parla al mio cuore digli che sai
Dei miei dolori che non dormon mai
Parlami o stella
e dimmi se lei verrà
Notte d’agosto e dei desideri
Cerco amore e vorrei che s’avveri
Lei che sorride passando per la mia via

Ah, com’è difficile spiegare
Ma tu stella amica
Dimmi se resterà …

Dell’amore non si sa
quando viene o se ne va
dell’amore non si sa
quando sarà
da dove arriverà

Stella sorella dei sogni miei
parlami ancora fino a domaini
dimmi se è vero
che lei esiste per davvero

Ah, com’è difficile sperare
Ma tu dimmi sempre e
Solo la verità...

Dell’amore non si sa
quando viene o se ne va
dell’amore non si sa
ma quando amore arriverà
tutto intorno cambierà
nella notte brillerà

… tutto cambierà ... tutto rivivrà con te

The best.

  • Smell: Bleu.
  • Taste: Strawberry.
  • Colour: Caramel.
  • Texture: Silk.

Do you know what I'm talking about?

Zapatos de mi conciencia

Letra y Musica: Alí Primera.

Lo que digo en este canto
es la historia de un encuentro
que tuve con un anciano
y su antigua poesía
las dos rosas de sus manos

Me dijo llegar temprano
es ver las cosas de frente
y además te queda tiempo
para mirarlas dos veces.

Al ver al viejo descalzo
quise darle mis zapatos
y me dijo "no hace falta"
lo que importa es tu conciencia
no es importante el ropaje
sino distinguir a fondo
los que van comiendo dioses
y defecando demonios

El viejo tenía la piel
marcada por latigazos
pues la miseria de ayer
seguía saliéndole al paso
y contó que en su pasado
no quiso ser Dios no héroe
en los dioses nadie cree
y a los héroes le condenan
a convertirse en estatuas
que ante las aves dan pena
de verdad que las estatuas
bajo las aves dan pena.

* Zapatos de mi conciencia
mal que bien me van llevando
zapatos de mi conciencia...

Si tu vas por un camino
te gritan de lado y lado
no detengas tu marcha
tan sólo para escucharlos
siempre encontrarás la altura
en que todos puedan verte
y en la que puedas inclinarte
sin peligro de caerte

* Zapatos de mi conciencia
mal que bien me van llevando
zapatos de mi conciencia...

Alli.

Aun estas alli, desangrandote mientras yo, desafortunado, contemplo tu desdicha... sin saber que tambien es la mia. Con cada segundo que pasa, la sangre se torna mas oscura, y la falta de oxigeno que te tortura hace que muera instantaneamente una parte de mi ser. Tus ojos, mas profundos que lo usual, han tornado en un tunel que pareciera no tener fin... Y yo, que no me resigno a perderte me he lanzado a esta foza para salvarte o morir en el intento.

Aun estas alli?

Enigma.

Toma el arma, fria y pesada, con toda su carga, sin pensarlo apunta desde su garganta a su cerebro. Tira el gatillo y siente como el metal atraviesa su piel, rasgandola de manera despiadada y dolorosa hasta que la bala se funde en su craneo con el organo pensante, quedando asi en un inanimado estado de ebriedad...

(Sobresalto)

Depierta en la cama, aun consciente pero moribundo, luego de haber cortado sus venas con una filosa hojilla, que abrio paso en su piel como un trineo que se deslisa montaña abajo en la estacion invernal. El oxigeno comienza a faltar. En vano es el esfuerzo de respirar, pues la sangre ha teñido las sabanas y continua la erupcion del magma vital. En un segundo el cuerpo se desploma...

(Reacciona)

Abre los ojos mientras en el aire sus pensamientos se congelan. Un segudo pasa a ser un año, y cada minuto es una nueva vida. El arrepentimiento. Los recuerdos ya no son mas oscuros, ahora lo ve, la luz y el regalo de vivir. Pero es demasiado tarde, solo un milisegundo mas y su cuerpo estara estrellado contra el suelo. Siente como su rostro se deforma continuamente al colicionar el duro asfalto. El molesto polvo ahora forma parte de la masa que yace sobre la avenida. Lo que nadie sospecha que aun un pulso electrico le recuerda que el dolor existe.

(Exala)

Con el ultimo aliento, deja que el aire salga de sus pulmones, y logra, impotente, ver las burbujas alejarse al tiempo que el agua invade cada lugar posible. Se van las esperanzas y no hay vuelta atras... ahora sin fuerzas y mas pesado. Las estrellas se hacen tenues, pero sabe que ahora esta cada instante mas cerca de ellas.

-----

Polvo eres y en polvo te convertiras.

-----

No comments...

Cierro los ojos y salgo volando por la ventana.
Las estrellas me guian, el oscuro cielo es mi compañero de viaje.

Como un sahueso sigo el olor de tu piel a traves del espacio infinito, entre galaxias y polvo de estrellas, mas aun asi es un camino directo.

Importante, y latente, siempre viva y alegre. Asi te recuerdo, asi eres y seras. Te encuentro y te pierdo, te tomo y te escabulles entre mi dedos, te sigo y te escondes.

Un recuerdo, omnipresente, navega por el mar de mi memoria... sobre el flota cada barca, y pasajero de lo vivido. Yo, hecho de ti, y tu de mi.

It's late. You're coming... I'm gonna find you wherever you hide.

Dejad!

El tiempo ha pasado y nada ha cambiado. Que ha pasado?

Problemas y soluciones aparecen y desaparecen en el horizonte, mas, el punto fijo en torno a lo que todo gira, se mantiene invariante a pesar de las lunas que pasan. Un terremoto, una tormenta, un nuevo dia o noche... aun esta alli.

Renacer? Is this a cruel joke of destiny?

News

Wow, today finally I could return to the blogger, for some reason it didn't work for me last week.

It was a nice week, in physics I did my first electroweak cross-sections and plots (all those that know me can imagine the turn in my life, he he he...), so, now I can tell you for sure that in a high energy annihilation e-,e+ the 2W channel dominates over the Z,H channel.

I'm finally understanding the renormalization group... Callan-Symasnik equations, RG flow and of course the running coupling constants.

In the personal, the best new in the week is that Alejandro is beginning to walk in the `andador'... so he's a grown boy, he he he.

That all (more or less), Bye.

Punto de Vista

- No Sr. Smith!!! Nooooo...

Pero fue demasiado tarde. Su cuerpo ya estaba suspendido en el aire, solo bajo la action de la gravedad, que lo conducía rápidamente a su inevitable destino. En tanto, el correr del viento jugaba con su larga cabellera, aquella que cuidaba con tanto empeño, el rozar del viento, ligero al inicio, fue transformandose en un verdugo de las lágrimas que de sus ojos brotaban.

- Es el final - Se dijo para si.
-...oooooo... - continuaba el grito del Sr. Gutenstein, quien durante varios meses acompañó a Sr. Smith en su atareado labor.

Las personas aún sin percatarse caminaban exsaustas por las aceras de esa cuidad en penas.

- Hace mucho tiempo que estamos muertos. No es el final, es el principio pues ya estabamos muertos. - Continuaba pensando el Sr. Smith.

El tiempo era ahora infinito. Mientras mas deseaba estrallarse contra el suelo, parecia dilatarse más y más el tiempo, quedando en un reposo casi absoluto. Todía observar cada cosa, cada detalle... recordar de principio a fin no solo su vida, sino las palabras, los versos, las sonrrisas, incluso cada frase de La Biblia, aquella a la que recurrió cientos, quizá miles de años atrás.

- Es imposible!!! - Exclamaba.
- ... ooooooo...

Ahora flotaba en el aire, como un acto mágico del que no podía escapar. El tiempo se detubo, no un segundo, sino por una o mas eternidades. Desde su pues to en el aire observo un universo inmovil, absurdo, patético y cuyo equilibrio ha sido maltratado una y otra vez. Sintiose vivo entonces, pues logró descifrar los misterios del espacio, del tiempo (si es que no son lo mismo), así como la existencia paradigmática del todo y su opuesto. Se percató que el cuerpo ya no lo limitaba y su Qu (o alma o espirítu) pudo teminar la agonía que lo perseguía.

Y mientras al final de los tiempos su Qu se elevaba aun más alto que lo concebible por el hombre, otros tan solo podían ver un cuerpo esparcido sobre la calle, sin vida. Al menos no como ellos la conocian.

Movies and entertainment.

Last weekend I saw The Tuxedo a nice movie of Jackie Chan. It was funny... specially when you see the backstage.

Through the week I saw the 4th season of The 4400, well... until the 11th episode.

Today, looking for information at IMDB.com, it was surprising that the movie The Shawshank Redemption is 2nd in the ranking of best movies. I thought that just I like that movie, specially because always, when I ask someone for the movie, they say.. ``I've never seen that one"

Another curious thing is that no one here seems to remember the song Barcelona, the one of the Olympic games, Barcelona '92. Weird,Isn't it?

Que frio mas bárbaro!!!

Estoy que me congelo. Y de paso no me siento muy bien de la garganta. Porquería.

Bueno, la semana proxima viajo al sur de Chile (A Panguipulli) para buscar a Lea y Alejandro. A ver si por fin puedo cuidarlos a ambos, jejejeje.

Termino este post diciendo, C*** que friiiiiiiiiiiiiiiiiiiiiiiiiiiio

Resume...last 10 years.

September 1997.

Just ten years ago I began to study physics... yes!, what a long time. Since that, my live has changes a lot.

All the dreams of a teenager, the expectation of the new school, the curiosity and the thirst of knowledge. As every body knows, ``la vida te da sorpresas'', and mine is not the exception of the rule.

Best moments.
  • My first semester... I was the best student in the faculty.
  • First class on physics... even if it does not remain the whole course.
  • Marco Rodriguez's lectures... and friendship.
  • To study music.
  • Return to physics school after a quit of about one year.
  • Working together Alejandra and Pantoja.
  • THE BEST OF ALL: my friend... all of them (do not expect I write the name of all... I really want to get my PhD soon!!!)
  • To study in Trieste at ICTP.
  • To learn English and Italian.
  • Coming to Chile.
  • The birth of Alejandro.
  • Last one: Qualifying as PhD.

Worst moments.
  • To say bye of the people I have known... even those I just met one week.
  • To be treated like an asshole... by to many people even in Italy as well as in Chile.
  • To loss a PhD possibility and even worst, the scholarship... and having to return some money back to the sponsors.
  • et cetera...

``Gloria patri et filii et spitui sancti"...

Today is a new day, after 10 years I finally feel I'm getting somewhere.

Opportunities: Well, there are still some cloud in front of the way, but as it seems the next crossroad will guide me into wonders of cosmos or the ultimate advances of particle physics.

The first one is an opportunity to work with Jorge Zanelli (the person I owe my actual success) studying different stages of Chern-Simon theories and other possible gravity theories available.

The second one is as great as the first... to work together with the Santa Maria's professors in collaboration with CERN, it represents a change to go Switzerland itself and perhaps working with people like J. Ellis or Alvarez-Gaume.

I just hope that whatever the result will be... it'll be the best choice.

Names:

Alejandro Salas, Freddy Ramirez, Faviola Molina, Aureliano Skirzewski, Alejandra Melfo, Luz Rivero, Cesar Lucena, Nadia Marchan, Marco Rodriguez, Carol Lupidi, Bobby Acharya, George Thompson, Jorge Zanelli, Joel Saavedra, Olivier Espinosa, Claudia Gonzalez, Claudio Dib, Ivan Schmidt, Leandra Riquelme and Alejandro Castillo. Do not forget: Katania Felisola, Alfredo Castillo, brothers and sisters (6 of'em), Margot, Jessica.

Success of a Project

For a long time I've been interested on improving science education.

Today we move a step ahead in the evolution chain.

We've begun a series of seminars from student, for students... this a space for learning and discussion. As heads of the project my colleague Adolfo Toloza and I, began with exposition of several topics in mathematics (by myself) and a geometrical derivation of the Lorentz transformation (by Adolfo).

People seem to be interested, so let's hope it'll keep going.

Candidato a Doctor

Finalmente, despues de mucho esfuerzo y trabajo, hoy me dieron la noticia que aprové los examenes de calificación, asi que a partir de hoy paso a ser candidato a Doctor.

Muchas gracias a todas las personas que me han apoyado durante mis tiempos de pena y cuya confianza mantuvo mi entusiasmo e hizo renacer el amor perdido hacia mi carrera... que de una u otra manera paso por momentos a ser un karma mas que un gozo.

Este triunfo es no solo para mi, sino para todos ustedes. Miles de gracias a todos.

Y ahora... vamos por los ultimos cursos y la investigación.

I'm praying for this "as good as it gets"

Cya soon.

Movies...

Long time ago, a good... sorry, an excellent friend of mine, Cesar, recommends me a cycle of movies based on musics.

Some of them were, Amadeus, Farinelli, Shine and The legend of 1900.

If you see the list of my favorites (just to your right), all of'em are there. Unfortunately, I got just one of those, say Amadeus. And just one (may be 2) weeks ago I got The legend of 1900.

Nonetheless, this weekend I found the other 2. Yesterday morning I saw Shine... and next weekend I'll see (once more) Farinelli.

For more information check the web site IMDB

Electrodynamics

So... Here I'm studying electrodynamics for today's exam.

What about it?
Well, this is about magnetostatics, electric and magnetic field on matter... you know, all that stuff on polarization, magnetization, hundred of different names for the constants which appear on your problem, and even Laplace equation, diff. eq. on power series, and of course (one must never forget it) Boundary Conditions.

Through the day I expect to make a review on the concepts, and (if I can) a formulas book.


Oh!, I finally get how to pass to the covariant formulation of the electrodynamics in a smooth way. Sooner I'll put something on my Math and Phys page, but if you are in a hurry, just check the second volume of Feynman's lectures on physics. I'll go mostly through that.

Some nice books I've studied from are:
  • Feynman. Lectures on Physics. Vol. 2
  • Reitz and Milford. Foundations of electromagnetic theory.
  • Griffiths. Introduction to electrodynamics.
  • Lèvy-Leblond and Butoli. La physique en questions: Electricité et magnétisme.
  • Alonso and Finn. Campos y Ondas.
  • Purcell. Berkeley Series Vol. 2
  • Jackson. Classical Electrodynamics. (In my humble opinion, It's an excellent book of reference, but is not a good book for studying... Nothing personal. I know one should work it down at least once in a live time)

Enjoy life... Cya.

YAHOOOOOOOOOOOOOOOO!!!!!

I cannot believe this:

I got a 95%....

JUST DO IT!!!!!!!!!! As Nike

Not so well, not so bad.

I got the mark of Statistical Mechanics' last examination, was not so bad... but ok.

Review:
  • First evaluation: Exam 73%, Homework 93%.
  • Second evaluation: Exam 75%, Homework ??%.
So, even better than the first but not as well as I would.

Ah!!! Today I'm gotta talk about properties of the partition function... Let's see!!!

C U in another life.

Que comida tan buena!!!!

Hola gente:

Este post no esta en Inglés porque simplemente, su contenido no puede ser descrito de otra forma mas que en la lengua madre.

Ayer, domingo (no se que fecha) pase media mañana cocinardo.
  1. Carne: primero de sancocha, se esmecha.
  2. Sofrito: cebolla, pimenton, ajo y un chorizo.
  3. Caraotas: agua y candela... hasta que ablanden.
  4. Arroz: con unas rueditas de cebolla, un ajo y sal.
  5. Caraotas 2: una vez blanditas se le echa el sofrito y se cocina un rato más.
  6. Carne 2: se guisa la carne esmechada con tomate y algunos aliños.
  7. Tajadas: se taja un buen plátano maduro y se fríe.
  8. Otros: un huevo frito... y un trozo de queso.
Si señor.... un tremendo PABELLÓN CRIOLLO. Lo único que faltó fue un joropo bien zapateao.

VIVA VENEZUELA CARAJO!!!

Properties of the Partition Function.

After a course on Statistical Mechanics... including thermodynamics, phase transitions, statistics, ensembles (micro-canonical, canonical and grand-canonical), Fermi-Dirac and Bose-Einstein statistics, I should give an exposition on the properties of the Partition Function.

Reference:

Kerson Huang. Statistical Mechanics. Chapter 9.

Now, reading this chapter I could understand most of the different things we're dealing on though the course.

La laggenda del pianista sull'oceano

After trying very hard to get the movie "The legend of 1900", finally I found it, so new I've the Book called "Novecento" (in Spanish), the movie (In Italian)... but the most amazing is a lecture of the original book, You can find it in the archives of Rete Due.

If you understand some Italian you must hear it.

Here is the link... Enjoy it

Statistical exam today... :-(

Well people...

First exam was not bad... a bit more than 70%
First Homework, more than 90%.

So, today I don't wanna do it worse than before. Let's see what happen.

Growing faster.

Last Tuesday Alejandro was to a medical checking... the one of the first month.

He's 1.5 Kg heavier and 6 cm taller than when he was born. Not bad at all. :-) The only thing is that this rhythm of eating will make us bankrupt, he he he...

See you soon. :-P

So... a good day!!!

Despite yesterday began raining, everything change after knowing the result of an exam on Electrodynamics.

It really makes me feel proud... I got a 95%.

Moreover, Life is changing and working a new way out.

New stuff

I got two new books for my personal library,
  1. Lie groups, Lie algebras, and some of their applications. By Robert Gilmore.
  2. Quantum Mechanics. By Albert Messiah
Both of'em publish by Dover.

Moreover, I also bought the "Pulse" DVD by Pink Floyd...

Now, it's time to enjoy all of it.

Being a father.












On April 24th, I became father... his name is Alejandro Javier (you can visit the blog http://alejandrocastilloriquelme.blogspot.com .




He's quit nice guy, doesn't cry to much, he's barely awake... but eats almost more than me.




Just two days before his birthday we went to Viña del Mar to walk... here there're some pictures.

Fighting against Windows Vista

Last week Leandra bought a new notebook... of course, by default it cames with Windows, moreover, the Vista version.

It seems almost impossible to get into this new operating system.
  1. One is used to use a bunch of different programs in, let's say XP... but they don't work in this new plataform. Ex.: Real Audio. Furthermore, WMP is not allowed to play such a format.
  2. If you wanna install a free antivirus... that's an Odyssey (at least for me).
  3. Vista is felt to be slower than its antecedent XP.
  4. Among others...
But at the end I could install (after a lot of work) AVAST's antivirus, JAVA, MIKTEX, TEXMAKER, GV, and certain programs I use frequently.

Nevertheless, Vista has an advantage over XP, it has all the needed installation `codex' for the printers, USB, et cetera.

New reading

I've been quit for a long time in the reading matter. Nonetheless, from time to time I get warmed up again and start to read.

Last 4 weeks I read my first whole book in English, The Godfather by Mario Puzo... incredibly, I spent just 3 weeks on read it. Also, last week I read Fahrenheit 451 by Ray Bradbury. Finally, last night I began to read A gift of winds by Richard Bach.

It's been nice enough to re-meet our old friends... books.

What is all this about?

Yesterday I got bad news, they're not going to give me a grant. Amazing, Isn't it?

Well, I don't gonna give'em the pleasure of seeing me under their thumb. I can do whatever I should.

Trip to Pucon and Villarrica.

Welcome to Pucón, it's one of the most famous touristic place in Chile.
The image you see above is the "beach" of Pucón, Why I'm using quotation marks? 'Cause is a Lake and not sea... what's a beach for me is.

Next two pics, show my "laws" family. Leandra... you already know her, Cristina (her mother) and Roberto (her father). Don't forget Alejandro.


This last pictures show Villarica's volcano which is active, and you can see its smoke.

My new departent





This year is bringing a lot of new things and feelings, one of them and most important, Alejandro. But now, by first time I rent an apartment.

If it's true, it has just 1 room, living, kitchen and bath, is the nicer place I've ever rent. Moreover, it's not so expensive, around 200 US$ monthly.

Nonetheless, I bought lots of things... washing machine, two place bed (including its furniture), et cereta.

Great... now I'm feeling like a future father.




Oscar.

Echo...





For all those still don't know, I'm gonna be father on May.

She is Leandra, an inside her belly is Alejandro...


Oscar.

Panguipulli

I spent my `free' time in Panguipulli, it's a town in the 10th (oh, sorry now is 14th) region in the south of Chile.

Here is the main square of the town.










This is one of the vast amount of vulcanos all over Chile














The sight from the shore of the Lake Panguipulli.














Again the vulcano...














Another view of the Lake














This last two photos are the Huilo-Huilo (a local river) and an island on the Lake Pirihueico.

Assistant of Quantum Mechanics.

He he he, after all, I come back to my basis... Once more I'll be assistant on Quantum Mechanics, say the first volume of Cohen-Tannoudji.

Students... Be care, I'm coming.

Oscar.

Particle Physics in Reñaca.

Wow, It was not enough with a bunch of string theory... I attend just two weeks ago, the 4th CERN Latin American School on Particle Physics...

I spend a wonderful time learning about the other side of physics, experiments... and even phenomenology. That's a lot of work.

I did not know the huge amount of energy, money and effort people should put to develop this particles accelerators, and forth to analyze the bunch of data. Moreover, after all that work you must find the correct (let's hope) theory to explain the facts.

"Physics: Where the action is" as I think Feynman said.

Ah!!! Almost forget the best new. I was assigned to write the lecture notes of John Ellis on Cosmic Microwave Background. Such a nice experience.


Oscar.

Bariloche











Last January I went to Bariloche - Argentina, in order to attend a School on String Theory.

It was a great experience, I re-met three of my old diploma professors, George Thompson, Seif Randjbar-Daemi and Kumar Narain. Additionally, I met Ana Maria Font... after a long time, and David Tong.. he a great guy and he put lot of energy into his lectures. Second time I meet Nathan Berkovitz, Stefan Theisen and Carlos Nuñez.

Definitely I learn a lot, and the best part is I got the 5th place in the exam, not bad for a non stringer.. he he he.
