For those of you that still remember the good old days of core dumps, here’s a post that follows that philosophy.😉

It’s been quite sometime since i last had a chance to put some content here on the blog, nor have i had time to expand on the interesting comments that have appeared and so on… time has been short lately.

In some sense, this is good news: *research* has really taken the best of me (as opposed to, *e.g.*, some of the network management tasks that have plagued me in the not-so-distant-past😉 ) — last week i gave a talk at Syracuse, and if all goes well, maybe i’ll be able to talk a bit about it here.🙂

Hearts will never be practical until they can be made unbreakable.

Pô, fiquei realmente chateado com a notícia da morte do Wheeler…

Mas, mudando de pato a urubu, aproveitando a “thread” da sua palestra

em Syracuse, saca só essa notícia (tem já quase um mês, “but anyway”…):

Higgs seen at the LHC

http://www.newscientist.com/blog/shortsharpscience/2008/04/higgs-seen-at-lhc.html

Infame, mas irresistível…;-)

Cheers,

Pedro

P.S.: Como anda o Balachandran?

Grande Pedrão!

Ah… a “NewsScientist” ataca novamente…😦

O ‘truque’ nisso tudo é uma coisa só: personal publicist (o Higgs tem um, contratado pela Edinburg University). Isso pra não falar no fato de que o bóson só é chamado de “Higgs” porque o Hagen (co-autor do artigo do Guralnik) tinha uma animosidade com o cara (cujo nome agora me fugiu) que “batizou” a partícula — coisas da história… que teve uma ajudinha duma greve de correios em Londres.

Agora, quanto ao Balachandran… vc acredita que ele me reconheceu?!!! Eu não botei uma fé: ele abriu uma memória elefante-yoga e desceu o cacete: “eu lembro de vc assim e assado…” Foi massa!🙂

Mas ele ma pareceu estar bem.

Um abração, []’s!

Memória de Ganesh… É, mas esse é o Bala… Ele deve vir a Brasília

esses dias durante o mês de maio, pra trabalhar com o Amílcar. Eu o

conheci em 2004, quando ele estava visitando o Teotônio. Ele me pôs

em contato com a Sumati Surya num momento em que eu precisei de uns

truques de atraso temporal gravitacional de geodésicas nulas para

o meu trabalho, e ele participou em alguns seminários informais de

uma série que eu apresentei em 2004-2005 lá no DFMA escrutinando o

artigo do Romeo (Brunetti), do Klaus (Fredenhagen) e do Rainer (Verch)

sobre teorias quânticas de campo localmente covariantes, que eu usei

depois extensivamente na minha tese.

Quanto à história do Higgs, o Wreszinski tinha me contado um

pedaço. Disse que o Hagen teve um treco na época…

Cheers,

Pedro

Olá Daniel. Gostaria de pedir linkagem ao LDC, se possível. Muito obrigado! []’s!

OMG. Have you even read the abstracts of all this stuff? Anyway, thanks for the new motivic links.

Hi Kea,

In fact, i always try to read the arXivs everyday, and make my personal “selections” accordingly — even if i don’t post them here that often.

What happened in this particular case is that i ended up accumulating about 1 month of this information… hence this “core dump”. (You can check the particular date range comparing this post’s date with my last one’s.)

As for reading the abstract… i never put something here that i haven’t personally “sanctioned”. Now, you can obviously criticize this subjective method of mine — but, there is a method.😉

Personally, i offer this to help ease your thoughts (if it helps at all): once you realize how different topics are connected and form the picture of current research in Physics (and Math), it becomes a bit easier to put things in context and understand what are the starting points and what is being sought as a result. Besides, having lunch (and the following coffee time😉 ) with some of the faculty from the Physics and Math Depts really helps.🙂

Cheers.

Gustavo,

Nao foi ‘mah feh’, foi pura falta de tempo de organizar a vida aquem duma serie de compromissos que tinham precedencia.

O link vai aparecer em breve.😉

Gustavo,

Serah que vc poderia confirmar o site do LDC pra mim?

Eh que eu estou recebendo um erro da ‘JProfiler’…
