Quando ero bambino trascorrevo interminabili pomeriggi nel paese dove abitava una delle mie nonne. Specialmente durante l’inverno, poco interessato ai risultati delle partite di Serie A e attanagliato dalla noia, mi capitava di guardare dalla finestra le luci provenienti da un altro piccolo centro abitato, abbarbicato sulla cima della collina di fronte. Le luci delle … Continue reading La Teoria della Relatività: Generale, Ristretta, Speciale o meglio Locale
Less is more Less stuff, less waste. It's as simple as that. In fact, some people are actively advocating what's sometimes called "happy degrowth", i.e. embracing a new kind of global economy based on an ecological paradigm and essentially rejecting capitalist ideas. Degrowthers believe we need to shift to a more modest lifestyle as … Continue reading Virtual Reality will solve our problem with Global Warming. Or maybe not.

The book, as you can imagine from the title, recounts the story (so far) of the two Vogayer spacecrafts, and of the people who made this possible. There is also a … Continue reading Touring the Solar System

In fact, this phenomenon is not a direct consequence of any profound … Continue reading Live Blogging: Solar Eclipse 2017

For some reason unknown to me, the Belgian-Russian physicist was awarded the honorary citizenship of my hometown - an honour later awarder to another Nobel laureate, Gerard 't Hooft - so maybe … Continue reading Of Time, Entropy and Consciousness
This post is not about politics, but the failure of statistics applied to politics. Our technology, the science behind big data, Bayesian statistics, and ultimately their incarnation in Nate Silver's model, all crumbled down last night. Sure, the FiveThrityEight blog keeps saying that there was a high level of uncertainty associated with the polls, mostly due … Continue reading The Scariest Thing of All
Disclaimer: this is a blog post, not a paper. Seriously, I'm not suggesting to build such an accelerator, but I believe that by trying to answer this question the reader can learn something about the intriguing realm of accelerator physics. The Large Hadron Collider operating at CERN is the most powerful collider ever built by … Continue reading Why don’t we build a particle accelerator orbiting the Sun?
