The potential of the comprehensive formalization of mathematics has fascinated me for quite some time - even though I am a working mathematician whose research is not part of the area conventionally known as “formal methods”. Last week, I took the opportunity to attend the QED+20 workshop which was part of the Vienna Summer of Logic and which celebrates anniversary of the original QED workshops and manifesto. 20 years ago, the QED project set out to create “a computer system […]

Frank de Libero writes: I read your Chance article (disproving that no one reads Chance!) re communicating about flawed psychological research. And I know from your other writings of your continuing good fight against misleading quantitative work. I think you and your students might be interested on my recent critique of a 2011 paper published […] The post Skepticism about a published claim regarding income inequality and happiness appeared first on Statistical Modeling, Causal […]

So I have been getting some feedback lately on how I always assume everyone has a crush  on me. People know this is my typical assumption because I say things like, “oh yeah that guy totally has a crush on me.” And when I say “feedback,” what I mean is people joyfully accusing me of […]

I recently ran across PSReadLine, a project that makes the PowerShell console act more like a bash shell. I’ve just started using it, but it seems promising. I’m switching between Linux and Windows frequently these days and it’s nice to have a little more in common between the two. I’d rather write a PowerShell script […]

I’ve just uploaded to the arXiv the D.H.J. Polymath paper “Variants of the Selberg sieve, and bounded intervals containing many primes“, which is the second paper to be produced from the Polymath8 project (the first one being discussed here). We’ll refer to this latter paper here as the Polymath8b paper, and the former as the […]

I was only able to get to two days of the arithmetic statistics workshop in Montreal, but it was really enjoyable!  And a pleasure to see that so many strong students are interested in working on this family of problems. I arrived to late to hear Bjorn Poonen’s talk, where he made kind of a […]

posted by @ulaulaman about #globalwarming http://t.co/VDlaEt2s5m The physician Mark Schleupner, a Ronaoke native, writes about global warming: So, according to NASA scientists, if all the ice in 14 million sq km Antarctica melts, sea levels will rise more than 200 feet. Greenland alone has another huge chunk of the Earth’s water tied up in ice; some scientists say that its ice sheet has passed a tipping point and will be gone in the next centuries, raising ocean levels by 24 feet. These […]

Rather than staying in one of the conference hotels, I followed my habit of renting a flat by finding a nice studio in Cancún via airbnb. Fine except for having no internet connection. (The rental description mentioned “Wifi in the lobby”, which I stupidly interpreted as “lobby of the appartment”, but actually meant “lobby of […]

The title of this post is a nod to Terry Tao’s four mini-polymath discussions, in which IMO questions were solved collaboratively online. As the beginning of what I hope will be a long exercise in gathering data about how humans solve these kinds of problems, I decided to have a go at one of this […]

Non ricordo più per quale motivo la recensione non è arrivata su LSB con il suo iter regolare, ma avendola ritrovata, la recupero per DropSea:Le favole hanno da sempre il potere di veicolare in maniera semplice ma diretta alcuni messaggi importanti: non dare confidenza agli sconosciuti, stare attenti ai pericoli della vita. A volte, però, la vita è piena di eventi per noi incontrollabili e le favole possono aiutare a sopportarli. In un certo senso è quello che […]

Half-day #2 indeed at ISBA 2014, as the Wednesday afternoon kept to the Valencia tradition of free time, and potential cultural excursions, so there were only talks in the morning. And still the core poster session at (late) night. In which my student Kaniav Kamari presented a poster on a current project we are running […]

I managed to record this week’s Slate Money podcast early so I could drive up to HCSSiM for July 17th, and the Yellow Pig Day celebration. I missed the 17 talk but made it in time for yellow pig carols and cake. This morning my buddy Aaron decided to let me talk to the kids […]

I had an interesting discussion with Peter Dorman (whose work on assessing the value of a life we discussed in this space a few years ago). The conversation started when Peter wrote me about his recent success using hierarchical modeling for risk analysis. He wrote, “Where have they [hierarchical models] been all my life?

The first full day of talks at ISBA 2014, Cancún, was full of goodies, from the three early talks on specifically developed software, including one by Daniel Lee on STAN that completed the one given by Bob Carpenter a few weeks ago in Paris (which gives me the opportunity to advertise STAN tee-shirts!). To the […]

[Scott Sisson sent me this summary of the ABC in Sydney meeting that took place two weeks ago.] Following on from ABC in Paris (2009), ABC in London (2011) and ABC in Rome (2013), the fourth instalment of the international workshops in Approximate Bayesian Computation (ABC) was held at UNSW in Sydney on 3rd-4th July […]

E' interessante osservare come fino a una trentina di anni fa almeno l'industria automobilistica, almeno quella non italiana, aveva nella matematica una delle linee di ricerca fondamentali. In particolare ci sono due esempi cui sono incappato recentemente, le curve di Bézier e il metodo della continuazione.Iniziamo con le prime: le curve di Bézier sono delle particolari curve parametriche sviluppate dall'ingegnere Pierre Bézier per la Renault da utilizzare per il design […]

I spoke (remotely) recently at the University of Wisconsin, on the topic of ethics and statistics. Afterward, I received the following question from Fabrizzio Sanchez: As hard as it is to do, I thought it was good to try and define what exactly makes for an ethical violation. Your third point noted that it needed […] The post Ethics and statistics appeared first on Statistical Modeling, Causal Inference, and Social Science.

People who celebrate the monthly jobs report getting better nowadays often forget to mention a few facts: the new jobs are often temporary or part-time, with low wages the old lost jobs, which we lose each month, were often full-time with higher wages I could go on, and I have, and mention the usual complaints about the definition […]

Day zero at ISBA 2014! The relentless heat outside (making running an ordeal, even at 5:30am…) made the (air-conditioned) conference centre the more attractive. Jean-Michel Marin and I had a great morning teaching our ABC short course and we do hope the ABC class audience had one as well. Teaching in pair is much more […]

In the last period I cannot read the Notices of AMS, so I lost the most recent discussion on this journal about the revelations made by Edward Snowden about NSA. Thanks to the n-category Café I recover the letters about this topic: In the first part of 2013, Edward Snowden, a former contractor for the National Security Agency (NSA), handed over to journalists a trove of secret NSA documents. First described in the media in June 2013, these documents revealed extensive spying programs of […]

La settimana scorsa, su twitter, ho diffuso alcune immagini, foto scattate dalle pagine dal volume Letture da Le Scienze: Fisica delle particelle (un indice del volume), che raccoglieva alcuni articoli usciti sulla rivista italiana (e quindi anche su Scientific American). Poiché ognuna di quelle immagini fa inevitabilmente parte della storia della fisica, mi sembra sensato proporle raccolte insieme in un unico post molto più semplicemente raggiungibile di tanti piccoli...
