sta hocete, dobio je grant kod vrlo stroge agencije. nema veze sta ce posle biti, vazno je doci na naslovnu stranu univerzitetskog casopisa.da ne trujemo ovde previse, zaboravili smo mucene hemicare, vidi se da je forum pun fizicara...3425rib2.jpg

This year's Nobel Prize in Chemistry awards Venkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath for having showed what the ribosome looks like and how it functions at the atomic level. All three have used a method called X-ray crystallography to map the position for each and every one of the hundreds of thousands of atoms that make up the ribosome.
dve proslogodisnje dobitnice l'orealove nagrade su ove godine fasovale nobela. lepota i udesavanje!

Nobelova nagrada za fiziku 2015 (link):

 

Takaaki Kajita, Super-Kamiokande (SK) i

 

Arthur McDonald, Sudbury Neutrino Observatory (SNO) (jeeeeeee :))

 

za otkriće neutrinskih oscilacija (SK za atmosferske neutrine, SNO za neutrine sa Sunca)

 

SK je prvi detektovao kako neutrini menjaju svoj tip mereci fluks atmosferskih neutrina: mionske neutrine, detektovano ih je manje nego sto je trebalo da nisu oscilovali. Međutim, SNO je prvi eksperiment koje je nedvosmisleno pokazao da neutrino menja svoj tip tako sto je izmerio odvojeno flux elektronskih neutrina i ukupan flux neutrina (elektronski + mionski + taonski) koji dolaze sa Sunca.

Posto Sunce prozivodi samo elektronske neutrine, a SNO je dokazao kako je flux elektronskih = 1/3 ukupnog izmerenog fluksa, to je nedvosmisleno pokazalo da su oni promenili svoj tip (tj. "oscilovali") u druga dva tipa na putu do zemlje. Sve ovo se interpretira time da neutrini imaju masu, tako da se ovom nagradom posredno nagradjuje otkriće mase neutrina. Međutim, kolika je masa neutrina je otvoreno pitanje (i nova Nobelova nagrada u budućnosti), pošto ovi ekperimenti mere samo razliku između masa različitih masenih stanja neutrina. 

 

:wub:

 

p.s. ovo su direktori eksperimenata sa preko 100 ljudi u svakom. Bez svih tih ljudi ovo otkriće ne bi bilo moguće, ali neko mora da dobije nagradu   :).

Odnosno, ovi ljudi nisu dobili nagradu za odredjivanje mase neutrina (sto je samo po sebi otkrice veka), vec za resavanje tajne "nedostajucih neutrina", je li tako?

Ah, kad se setim te muke iz Opste astrofzike tamo neke 1993/4...;)

da, tačno tako, nisu dobili nagradu za određivanje mase, nego za rešavanje misterije nedostajućih neutrina, ali zbog toga i za potvrdu da neutrini imaju masu na osnovu neutrino mixing hipoteze. izmerili su mixing parametre neutrina što jeste fundamentalno (uglove i razlike kvadrata masa različitih masenih stanja neutrina).

Pošto je Abelova nagrada ekvivalent nobelovoj nagradi matematiku mislim da je ovo odgovarajući topic.

 

Andrew Wiles je dobio ovogodišnju nagradu

 

 

Professor Who Solved Fermat's Last Theorem Wins Math's Abel Prize

Mathematics professor Andrew Wiles has won a prize for solving Fermat's Last Theorem. He's seen here with the problem written on a chalkboard in his Princeton, N.J., office, back in 1998.

The mathematics problem he solved had been lingering since 1637 — and he first read about it when he was just 10 years old. This week, British professor Andrew Wiles, 62, got prestigious recognition for his feat, winning the Abel Prize from the Norwegian Academy of Science and Letters for providing a proof for Fermat's Last Theorem.

Now a professor at Oxford University, Wiles was at Princeton University back in 1994 when he worked out a proof for the theorem that had famously bedeviled mathematicians for centuries. As Princeton notes today, Wiles spent years attacking the problem, eventually working out the final proof with a former student, Richard Taylor.

The Abel Prize is sometimes called "the Nobel of mathematics." Wiles won it, the Norwegian academy says, "for his stunning proof of Fermat's Last Theorem by way of the modularity conjecture for semistable elliptic curves, opening a new era in number theory."

The academy also revisited the story of Wiles' deep ties to the famous math problem:

Wiles was far from the first to be captivated by Fermat's Last Theorem: The problem also lent its name to the 1996 best-selling book by Amir Aczel, who recounted how the problem described by Fermat also had roots in ancient Babylon.

"In 1963, when he was a ten-year-old boy growing up in Cambridge, England, Wiles found a copy of a book on Fermat's Last Theorem in his local library. Wiles recalls that he was intrigued by the problem that he as a young boy could understand, and yet it had remained unsolved for three hundred years. 'I knew from that moment that I would never let it go,' he said. 'I had to solve it.' "

From the 1996 review of that book, in The New York Times:

The Abel Prize carries a cash award of 6 million Norwegian kroner — around $715,000 at today's exchange rates. Wiles will formally receive the prize from Crown Prince Haakon of Norway on May 24 in Oslo.

"In 1637, while perusing Diophantus, whose historic importance is outlined by Mr. Aczel, [Pierre de] Fermat apparently had one of those flashes of deep insight that have produced historic leaps in the field of pure math. Everybody knew that it is possible to break down a squared number into two squared components, as in 5 squared equals 3 squared plus 4 squared (or, 25 = 9 + 16). What Fermat saw was that it was impossible to do that with any number raised to a greater power than 2. Put differently, the formula [xn + yn = zn] has no whole number solution when n is greater than 2.

"Fermat then wrote the phrase that has tantalized mathematicians ever since: 'I have discovered a truly marvelous proof of this, which, however, the margin is not large enough to contain.' The buried treasure, sought all these centuries, is the proof that Fermat said he had discovered but had no room to set down. In fact, when Mr. Wiles finally did prove that the theorem is true, he used techniques that could not have been known to Fermat, so whether the thinker of the 17th century really did have a solution to his problem cannot be known."

Znaci, ti neutrini stvarno postoje?

Čitao sam članak u Računarima o ovome pre dobrih 20+ godina, zašto mu nagradu dodeljuju sada?

Stvarno ne znam. Najverovatnije zato što je više akcenat na ukupnom životnom delu a ne na rešavanju nekog pojedinačnog matematičkog problema.

Velika je šteta što ranije nije dodeljivana nagrada...koliko je fantastičnih matematičara bilo u dvadesetom veku: Gedel, Turing, Erdos, Kolmogorov, Grothendieck, Andre Weil...

pozitivno iznenađene, po meni, za hemiju, dobili cryo TEM, 

tresla sam od živaca na pomen pervoskajta ili krispa ili litijum sulfat baterija.

 

ovo ujedinjenje fizike i biohemije puno znači, mogućnost korišćenja sinhrotrona je jako limitirana na samo određene centre, a i same intermedijere je teško kristalizovati, 

zapravo ceo taj proces je skup i dugotrajan.

cryo TEM može svakoj srednje razvijenoj institutciji da bude dostupan
