- It happens the same everywhere around the world. (The Yard)

-I was invited somwhere in the wold, by a friend, my friend make a lot of promisses. Promises which prefer to forget, now. He live in a house with several apartaments, with a shared courtyard. Since I am hosted here, and waith the promises come true, I see the same general dirt in the yard. - Time passes by working better. I said, and I grabbed with enthusiasm to clean. Gathering dried laves, collecting papers, sweep. A Lady , neighbour Lady, asked me, very surprised what I doing there . - Cleaning the yadr. I answered. - Because we get a lot of dirt in the house. - Yes she sayd. And she explained that the man who is responsable with cleaning dose not do his job. The inhabitants of the house will make a meeting, and they will solve the problem. This very ugly problem . - OK. I said, she left. While I cleaning the yard, I think what will happen now ? The man will be judjed, they will fire him . However, it is his duty. Or not ? I have collected numerous remnants of cigarettes, Ice cream papers, ...... Did we not have to respect the work of others ? - I asked myself. Why ?. 

- Maybe the man can not chase after everyone. And it looked like in the yard, is a competition. - Who throw more rubbish. It is easy to criticize, it is harder to help. For example: - do not throw trash in the yard. But, it is easier to judge . - This happen every day wherever in the world. We are different characters, but the same different caracters live worldwide, the only thing that is different is the country in which we live. Or where we come from. Richer country , or a poorer country. And it's good, they are poor countries, - We have forgotten how cleaning. They will do it. While I was cleaning, listening the album, The Wall (Pink Floyd and it fit well in the current situation.) I just remembered, my friend promises . - " Our home , our food , our work , life together ........." Yeah sure . Now my friend says he promised to much. In other words . Get out. Or , I 'm bored with this new toy. Thank God that we are not all the same. We are different characters. I have favorite quotes : - "Accept the things to Which fate binds you, and love the people with Whom fate brings you together , but do so with all your heart . " .... "Where I live if someone Gives you a hug it's from the heart . "...To tell the truth, I was very well tolerated in this house, I did not missed anything, for a time. Now my days are counted here, I think I've become an unwanted ghost. A sort trash. Why people do not understand, that promises must be respected. As a man's life may depend on promises. Those who are educated in the virtual world, forget the true world. - "Love all, trust a few, do wrong to none." - - I do not want to hurt anyone, especially my friends, my friend. I keep the pleasant memories. (Because it was. I was accepted and helped for a while. I must admit that. ) My friend wants to help me, even now. He'll tolerate my presence in the area. What great luck I have. Stupidity and reign are paid. I feel it now. - I continue to clean away, maybe I'll manage to clean, in my soul and in others soul. Maybe. But life will never forgive this fatal mistake, why I trusted my friend. Why ? - Because things are linked together, promise and trust. Okay, time to go, I do not accept any false help, and promises more. I'm going to clean in to another world.

A murit Murray Gell-Mann, fizicianul care a descoperit quarcurile
 

Fizicianul american Murray Gell-Mann, cel care a propus pentru prima dată ipoteza existenţei quarcului şi a primit Premiul Nobel în 1969, a decedat la 24 mai, la vârsta de 89 de ani, a anunţat duminică California Institute of Technology (Caltech), citat de AFP.

Considerat unul dintre cei mai importanţi fizicieni ai secolului XX, Murray Gell-Mann a formulat în anii '60, alături de compatriotul său George Zweig, o nouă teorie potrivit căreia particulele subatomice - protonii şi neutronii - sunt compuşi din particule şi mai mici. Aceste sub-particule au fost numite "quarcuri", termen inspirat de o propoziţie din romanul ''Finnegans Wake", de James Joyce: ''Three Quarks for Muster Mark!'' (Trei quarcuri pentru domnul Mark!).

Ulterior, experimentele au confirmat existenţa quarcurilor, care au devenit una dintre bazele fizicii cuantice.

Quarcurile continuă să se afle în centrul cercetărilor fizicienilor la ora actuală, în special a celor implicaţi în proiectul Large Hadron Collider (LHC) al Organizaţiei Europene pentru Cercetare Nucleară (CERN), cel mai mare accelerator de particule din lume, situat la graniţa franco-elveţiană.

În 1961, Gell-Mann a stabilit o nouă clasificare a particulelor elementare în grupuri de opt, în funcţie de caracteristici precum sarcina electrică sau rotaţia. Numită ''Cale octuplă'', teoria i-a adus în 1969 Premiul Nobel pentru Fizică.

Născut în New York 15 septembrie 1929, Murray Gell-Mann a fost convins de tatăl său să studieze fizica, ştiinţă care însă nu îl încânta. "Acesta a fost singura materie la care nu m-am descurcat în liceu, pe care am urât-o", a declarat fizicianul citat pe site-ul Caltech. "Apoi, după ce am ales fizica, a început să-mi placă. Am descoperit că tatăl meu avusese dreptate (...) Mecanica cuantică şi relativitatea erau lucruri minunate", a mărturisit el.

Gell-Mann a obţinut doctoratul la Massachusetts Institute of Technology (MIT) în 1951 şi a devenit profesor la Caltech în 1955 unde a activat până la retragerea sa, în 1993.

''Doctor Gell-Mann a avut această viziune clară şi această perspicacitate penetrantă, care i-au permis să observe volume mari de date din experimente şi să le dea un sens'', a comentat profesorul Hirosi Ooguri, director al Institutului Walter Burke de la Caltech, într-un necrolog publicat pe site-ul universităţii. ''El a deschis o nouă paradigmă în fizica particulelor", a adăugat Ooguri.
