Bom problema 
Alguém dá-me o seu número de telefone. A memória do meu telemóvel está cheia. Não sei que número hei-de apagar. Fico feliz com isso...

Orgulho nos colegas
Embora já lá tenha ido há duas semanas (obrigado Raquel pela fantástica visita guiada), não perdeu actualidade recomendar vivamente a exposição "À Luz de Einstein", a decorrer na Gulbenkian até 15 de Janeiro. A entrada é gratuita! Quem andar por Lisboa, não pode perdê-la.

Busy, busy
Gostaria de ter partilhado convosco a experiência da ida ao Estádio Municipal de Aveiro para assistir ao concretizar da qualificação da Selecção para o Mundial mas não houve tempo e entretanto perdeu actualidade. Gostaria de ter comentado aqui o resultado das Autárquicas (e em particular o comportamento abjecto de um tal de Carrilho) mas não houve tempo e entretanto perdeu actualidade.
Quem tem a vida cheia não tem muito tempo para blogues, principalmente quando são pouco visitados e deixam de ser novidade.
Terei que continuar a ser esporádico nas minhas intervenções mas prometo continuar a ir deixando aqui umas fotos, uns links e a manter actualizada a secção “cultura - últimos” (à direita) para que saibais o que vou vendo, lendo e ouvindo...

Uma visão muito particular de Portugal e dos Portugueses
Physics enlisted to help singles
Successful couples are said to have chemistry, but a study by an Oxford graduate suggests that dating may actually have more to do with physics.
Richard Ecob adapted a system for modelling atoms in radioactive decay to investigate how we look for partners. He found that "super daters", people who have many short relationships, have a good effect on others' lives. This is because they break up weak couples, forcing their victims to find better relationships.
Transit states
At the root of the system, says Mr Ecob, is the similarity between the probability of the nucleus of an atom decaying and that of a couple breaking up. The decay of a nucleus is described in terms of "transit states": the series of change it has been through to get to its current situation.
The probability of someone having been in two relationships, for example, is the same as that of a nucleus decaying twice.
"We had an inkling that it might be the same because we saw similarities," he told the BBC News website. "When we worked it out, the graphs we got were very similar."
To model the phenomenon, he wrote a computer program which placed "software singles", people seeking partners, in an imaginary social network. Each single had a set of interests, which they also looked for in potential partners. The research suggested that multiple daters, those who form many relationships, were less effective at finding the right partner than those who remained in one place and let
others come to them.
"If you have a complex network and you stay in one site you see more traffic coming through," he said. "It's a denser network, so there are more possible matches."
Another surprising discovery was that an increased set of preferences made no difference to a single's chance of ending up in a relationship. Despite modern people having more complex and varied interests than before, said Mr Ecob, this had no impact on their ability to date. So long as they were still willing to accept partners who met only a fraction of their criteria, the number of potential
matches remained the same.
Prestigious contest
The next stage of the project is to show that it can also be applied to business and political matches as well as it can to personal relationships.
"We think it'll match up the same," said Mr Ecob. "If you're with a phone company and you know they're not an ideal match, you're going to look for someone who is. It's a very similar situation."
Mr Ecob, who was recently awarded a first class Physics degree, undertook the study as part of his Masters research project. He worked closely with his supervisors, David Smith and Neil Johnson, who are now taking the study further. They have entered the project in the prestigious Science, Engineering and Technology Student of the Year awards, which will be presented in London's Guildhall next month.
