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?
In a previous post I used a dataset taken from my Facebook friends to debunk the claim that more babies are born under a new moon. I have now a chance to increase the test statistics significantly, not because in the meanwhile I made many more friends, but because people collaborating to the FiveThirtyEight blog … Continue reading Are more babies born under a new moon? – pt.2
After the two sophons arrive on Earth, their first mission is to locate the high-energy particle accelerators used by humans for physics research and hide within them. At the level of science development on Earth, the basic method for exploring the deep structure of matter is to use accelerated high-energy particles to collide with target … Continue reading Has Particle Physics Been Hijacked by ET?
The big news in particle physics during the winter 2015-2016 is certainly the excess found by the ATLAS and CMS Collaborations in the invariant mass of two high-energetic photons in the data acquired in 2015 at a centre-of-mass energy of 13 TeV. If you don't know what I'm talking about, then it's time to catch … Continue reading A few thoughts about the 750 GeV diphoton bump
How big is the biggest apple you could buy from your favorite supermarket? Surprisingly enough, you can actually give a reasonable answer just buying a bag of apples. In the example below, I weighed 8 apples and created a histogram with 5 bins in the range 100 - 150 g using CERN ROOT. TH1D * h = … Continue reading Comparing Apples to Apples
After I moved to Toronto, Canada, many friends keep me asking whether their hometown can fit into my new city's borders. Intrigued by their questions, I superimposed some maps taken from google, with same scale (1cm = 5 km). I also sketched an approximate border of Toronto to make the comparisons easier. What I've found … Continue reading Is Toronto bigger than…?
