5:04 PM | Magical modular furniture
#MIT #design #furniture #technology #Milano Transform is a magical, modular furniture developed by MIT: The work is comprised of three dynamic shape displays that move more than one thousand pins up and down in realtime to transform the tabletop into a dynamic tangible display. The kinetic energy of the viewers, captured by a sensor, drives the wave motion represented by the dynamic pins.The motion design is inspired by the dynamic interactions among wind, water and sand in nature, […]

2:57 PM | Journées MAS2014, Toulouse, Aug. 27-29
For those interested in visiting Toulouse at the end of the summer for a French speaking conference in Probability and Statistics, the Modélisation-Aléatoire-Statistique branch of SMAI (the French version of SIAM) is holding its yearly conference. The main theme this year is “High dimension phenomena”, but a large panel of the French research in Probability […]
2:49 PM | Lists!
People appear to love list. The Internet is full of lists. The 10 most popular dog breeds, the 10 biggest waves ever ridden by a surfer, the 10… you get the idea. The lists very often have ten entries, it’s … Continue reading →
1:47 PM | Looking for Bayesian expertise in India, for the purpose of analysis of sarcoma trials
Prakash Nayak writes: I work as a musculoskeletal oncologist (surgeon) in Mumbai, India and am keen on sarcoma research. Sarcomas are rare disorders, and conventional frequentist analysis falls short of providing meaningful results for clinical application. I am thus keen on applying Bayesian analysis to a lot of trials performed with small numbers in this […]The post Looking for Bayesian expertise in India, for the purpose of analysis of sarcoma trials appeared first on Statistical […]

10:46 AM | How recently have you experienced democracy? #OWS
A few weeks ago Omar Freilla came to talk to my Occupy group. Omar is a founder of the Green Worker Cooperatives and shared his experience as an organizer. He is a well-spoken guy and talked passionately about forming community cooperatives, where workers “have a direct role in decision-making and a share of all profits, build community wealth and help make […]

10:14 PM | MCqMC 2014 [closup]
As mentioned earlier, this was my very first MCqMC conference and I really enjoyed it, even though (or because) there were many topics that did not fall within my areas of interest. (By comparison, WSC is a serie of conferences too remote from those areas for my taste, as I realised in Berlin where we […]
5:12 PM | Timid medical research
Cancer research is sometimes criticized for being timid. Drug companies run enormous trials looking for small improvements. Critics say they should run smaller trials and more of them. Which side is correct depends on what’s out there waiting to be…Read more ›
1:46 PM | When you believe in things that you don’t understand
This would make Karl Popper cry. And, at the very end: The present results indicate that under certain, theoretically predictable circumstances, female ovulation—long assumed to be hidden—is in fact associated with a distinct, objectively observable behavioral display. This statement is correct—if you interpret the word “predictable” to mean “predictable after looking at your data.” P.S. […]The post When you believe in things that you don’t […]
11:22 AM | Let’s experiment more
What is an experiment? The gold standard in scientific fields is the randomized experiment. That’s when you have some “treatment” you want to impose on some population and you want to know if that treatment has positive or negative effects. In a randomized experiment, you randomly divide a population into a “treatment” group and a “control […]

One of the principle goals of the Simon-Marius-Anniversary-2014 has been achieved. The committee of the International Astronomical Union (IAU) responsible for the naming of minor planets, comets and natural satellites has announced that the asteroid “1980 SM” will in future … Continue reading →
2:30 AM | Commutative diagrams in LaTeX
There are numerous packages for creating commutative diagrams in LaTeX. My favorite, based on my limited experience, is Paul Taylor’s package. Another popular package is tikz-cd. To install Paul Taylor’s package on Windows, I created a directory called localtexmf, set…Read more ›

10:14 PM | adaptive subsampling for MCMC
“At equilibrium, we thus should not expect gains of several orders of magnitude.” As was signaled to me several times during the MCqMC conference in Leuven, Rémi Bardenet, Arnaud Doucet and Chris Holmes (all from Oxford) just wrote a short paper for the proceedings of ICML on a way to speed up Metropolis-Hastings by reducing […]

9:55 PM | Polymath8b, X: writing the paper, and chasing down loose ends
This is the tenth thread for the Polymath8b project to obtain new bounds for the quantity ; the previous thread may be found here. Numerical progress on these bounds have slowed in recent months, although we have very recently lowered the unconditional bound on from 252 to 246 (see the wiki page for more detailed results).  While there may […]
6:57 PM | The hidden costs of unsolicited textbooks — a view from the mailroom
In a followup to an earlier post about unsolicited review copies of textbooks, I had a chance to ask a student employee of our university mailroom about how these affect the daily workflow of mail services. His response was enlightening but, sadly, not surprising.

Kevin Cartier writes: I’ve been happily using R for a number of years now and recently came across Stan. Looks big and powerful, so I’d like to pick an appropriate project and try it out. I wondered if you could point me to a link or document that goes into the motivation for this tool […]The post Transitioning to Stan appeared first on Statistical Modeling, Causal Inference, and Social Science.

10:41 AM | People who obsessively exercise are boring
I’m not saying anything you don’t know already. I’m just stating the obvious: people who obsessively exercise are super boring. They talk all the time about their times, and their workout progress, and their aching muscles, and it’s like you don’t even have to be there, you could just replace yourself with a gadget that […]
6:50 AM | From when even the cars had moustaches
Every year about this time, my campus holds a spring celebration, with all the student organizations setting up pavilions in the park to sell food and advertise for new members, with the creative anachronists bashing each other with padded swords, and with a car show. Why a car show? I don't know, but I always enjoy seeing the variety of shapes and colors compared to today's mostly-the-same boxes. My favorite this year was a 1950 Chevy Fleetline, found rusting in a swamp in Tenessee; after a […]
3:45 AM | Big data, prediction, and scientism in the social sciences
Much of my undergrad was spent studying physics, and although I still think that a physics background is great for a theorists in any field, there are some downsides. For example, I used to make jokes like: “soft isn’t the opposite of hard sciences, easy is.” Thankfully, over the years I have started to slowly […]

10:14 PM | thumbleweed [local] news
It has been exactly a year since my climbing accident and the loss of my right thumb. Time for a quick recap (for anyone still interested!): Looking back over that thumbless year, I cannot see a significant impact over my daily life: I can essentially operate the same way as before, from climbing to cooking, […]
9:32 PM | Lightbot: imparare la programmazione giocando
Il computer che sto utilizzando per scrivere questo post è basato su una serie di microcircuiti elettrici (hardware) e una serie di istruzioni (software) necessarie per far sì che compia una serie di compiti (scrivere, far di conto e altre facezie del genere). Queste istruzioni, ovvero i programmi che utilizziamo per far funzionare il nostro computer, vengono scritte da esseri umani, i programmatori, e per farlo utilizzano le regole della logica. Un buon modo per abituarsi al […]

12:23 PM | Jurij Gagarin: a dream during an orbit
by @ulaulaman about #YuriGagarin #space_esploration #Russia #ColdWar He was born in Klušino on the 9th March, 1934; he died on the 27th March 1968, in a plane crash. His death and the controversy that followed and especially the pioneering gesture for which I remembered him today, make me pull over to Hal Jordan, a comic book superhero. In fact, Yuri Alekseevich Gagarin, when he returned home from his space mission, was celebrated as a hero, as a man who was raised on humanity in all […]
