Yesterday evening we enjoyed the second conference of the cycle. As rapporteur, we have the presence of one of the leading English astrophysicists. The curriculum Battaner Eduardo López , Burgos-blooded, it is impressive in every way. Although he describes himself as a "born teacher" , truth is that it emphasizes-much-as a popularizer and researcher. He is currently Professor of Astronomy and Astrophysics at the University of Granada. But not to stay all the ink, I would urge you to visit his personal web page , where he tells us all the details of his career in a fun and easy.
It so happens that Edward Battaner was a personal friend of Carlos Sanchez Magro, so its presence in Valladolid to give a lecture in honor of his colleague, was charged with emotion.
As usual, Inés Rodríguez Hidalgo , director of the Museum of Science, opened the session with another of his brilliant performances. Again, public assistance was a resounding success, demonstrating that this type of calls is very attractive and far outweighs the energy spent in its organization and coordination.
Ines Rodriguez presented to Professor Battaner .
Battaner brought a conference entitled History of Cosmology , history undoubtedly exciting. His presentation focused on modern cosmology, that is, bounded from the publication of General Theory of Relativity Einstein to today. The presentation used teaching resources (anecdotes, curiosities) that served to make more bearable the concepts explained, sometimes, the depth of these inherently intractable or unintuitive, and always using a language close and accessible.
The start of the conference.
In his talk, Dr. Battaner made a thorough review of all cosmological theories, under general relativity, appeared for most twentieth century. The diverse sample of these cosmological models fruition, as we know, in theory universally accepted, and today that best explains the observations: the Big Bang model. As with everything, there are always detractors and Battaner recalled at this point a quotation from St. Augustine, saying "heretics are needed" , meaning "in my opinion-that is always beneficial to any for the sector disagree rest of the scientific community does not rest on its laurels. Sequentially, in chronological order, the teacher told us about the Static Universe and the Cosmological Principle, the primeval atom Hypothesis, Steady State Model, primordial nucleosynthesis, the prediction of the microwave background radiation and subsequent detection, Cosmic Inflation and the accelerating expansion of the universe (dark energy). But is that theories are made by men, scientists, and they, with their shortcomings or their touches of genius, step by step, falling and rising again, make it possible to reduce the observed in nature to language that, if On success, being considered as a physical law. Thus, the conference recalled the characters that put the building blocks of current physical cosmology, from a relativistic point of view: Einstein, de Sitter, Curtis, Shapley, Friedmann, Hubble, Lemaître, Humason, Zwicky, Bondi, Gold, Hoyle, Gamow, Alpher, Penzias, Wilson, Guth. Some, predominantly theoretical, others bitter observers, but always complementary and aimed towards a common goal: understanding the large scale structure and dynamics of the universe, its origin, evolution and destiny. As Einstein said, "the most incomprehensible of the universe is that it is comprehensible" .
An expressive time of the conference.
A In my view, one issue that caught the attention of the audience was that of dark energy. It seems that the universe is expanding faster and faster and this effect is well explained by introducing dark energy as a repulsive gravitational force that accelerates the expansion. Thus, the "biggest mistake" Einstein-his cosmological constant, appears to be the end of the day a crazy idea. As said Battaner, "Einstein was right even when you make a mistake."
listening very concentrated Battaner one of the questions from the audience.
Syrma The librarian Battaner took several books for us to sign.
Portrait of family with some friends.
The turn to questions, was very lively, as the subject goes a long way and try many concerns and is appealing to the audience: How will the Universe end?, "Will expand forever?, Does our , is part of a larger multiverse? ... In short, we live an exciting time and I am sure that each of us went to our corner of the universe urbanite forcing our brains to these cosmological issues. In my case, I thought late last night in my universe, and that too in my time-space location, at six in the morning, inevitably, the alarm compressed air with its usual buzz. I'm here.
