Typhoon called Hack Julius Rosani
Wherever he goes, and anyone who comes into contact with this "natural phenomenon" completely upsets the listener, the next cyclone that will fall on the U.S. could easily call it by its name. I'm referring of course to Margherita Hack, professor emeritus of astronomy at the University of Trieste, February 6 he presented his new book "What's the weather which is "on Rai Tre. Indeed, more than the presentation of the book was interesting to hear what he had to say about issues important enough for the world of physics as that of mathematics. Having added the usual pinch of" Hack "to discourse, will be a little 'hard to stay on neutral tones, but I will try to sweeten the pill. Meanwhile, for those who want to hear the opinion of Mrs. Hack, without going through my filter, the public, the site link to the podcast rai:

For those who want to continue reading schematizzerò the contents of the interview and give some food for thought important in my opinion.
The first application for Fazio immediately brings un'afferazione interesting: Stars make noise and we possimo listen with the right equipment. The explanation lies in the fact that the stars emit light, or electromagnetic waves, radio waves, we can pick up via antenna and repeat as sound. One can thus distinguish a star like the sun, when it's calm (when its activity is minimal) emits a hum like the sound of wind from a pulsar whose sound is a continuous "bipp" with time intervals between a beep and the other order of a fraction of a second. Small way, the pulse is very dense neutron stars that have a very large magnetic field and perpendicular to the axis of rotation. So at every turn as if to send a signal to Earth each time that their magnetic axis is directed toward us. Their rotation is so high that making several revolutions per second. Despite these noises, the world remains silent to the human ear, because without the right tools these signals can not be received. Also, as the universe "empty", the sound does not spread though.
In conclusion, it is radio waves that are detected with sound, not sound real.
We are now in the second major issue of the interview. At Hack asked if in Italy we are in a position to study and do research. Very trivial, as I think everyone will know, the answer is no, in Italy you can not do research unless you consider the death of hunger or be kept on life from their parents. In fact many of our best brains go abroad to work and with excellent results. But what really interested in what it says the host of Fazio is that there would be a way to "work cabin" (as would my prof analysis) and that in theory the law is already in force but that "bureaucratic problems" is not applied. The idea is to do competitions every few years to promote those who are below in the university and make room for newcomers. If after a certain period you can not get a degree, must make room for others. This is obviously not the case. Apart from that the Hack points out that our universities are not to be thrown away, even those with a history behind are very, very good.
third point is the freedom or unfreedom of science compared to the state and the Church, above. The biological-science is no longer threatened by a lot, but the biological science still has problems with morality or religion. In fact, many important research, such as that on stem cells, are hampered by preconceptions moralizing, although their purpose is to do good, how to cure cancer. The living will is another aspect of the story, which is more difficult than it should because of this morality that must be maintained as a facade. If we look, it is right and moral to deprive an individual of the choice of how to live your life? (Another way, unfortunately on this subject can not avoid giving my opinion, but I would not become a topic of discussion, take it as my idea and nothing else.) So says Hack the cause of science knowledge for a freer and wider so a better life, hopefully.
It emphasized that, I quote directly, "scientists are well aware that science can explain everything. For example, we know very well reconstruct the entire past history of the universe, to the beginning, but if me wonders why there was the beginning? Why is the universe? "I do not know, is a fact that there is, and we study it." So the scientist can not give answers as to why in the world, he simply describes the how, but he does it well.
Finally, the last point, the fact that mathematics today is truly "snubbed". Foremost among my acquaintances, many even boast of not understanding the math. This may be due to the tradition of nineteenth-century scientist who saw in the small-minded man, as opposed to the philosopher but think big. Let me now go outside and hack reports part of a discussion between me and Thomas. Meanwhile, I would point to the philosophers, they are still at the starting point, because as I said to Thomas, the only way I have to correct errors or inaccuracies of their predecessors is to make a clean sweep of everything and start over . So get to the end is definitely more difficult, better to slowly build a world view based on the data that we have been left. Purely functional view of the world, again, no scientist wants to say why we exist. Furthermore, the fact to boast of not understanding the math is, in my opinion, a bit 'sad, because math is nothing more than human thought, logic and its consequences. I can understand that learning the multiplication tables by heart and wanting to be boring too little related to mathematics, that memory has little to do, but do not understand the proceedings do not mean to understand human thought, not knowing how to think or do not want to. The second case is the most frequent and the reason why we are sometimes very complicated situations, when with a little 'head would have been avoided. To think it is hard, but it's essential if you want to make the most of their lives.
conclude only recommend you watch the interview with Margherita Hack, whose content is far from being summarized in this article. I personally find that it can be a beginning towards an opening to free science and supported in Italy, if taken seriously, of course.
