6:36 PM | LOG#157. Superstatistics (II).
Following the previous article, now I will discuss some interesting points in the paper: Generalized information entropies depending only on the probability distribution, by O.Obregón and A.Gil-Villegas. You can find the paper here http://arxiv.org/abs/1206.3353 The Boltzmann factor for a generalized … Continue reading → Tags:  effective entropy, equipartition principle, equipartition theorem, F-distribution function, fractal, gamma distribution function, […]

4:10 PM | Imaging electric charge propagating along microbial nanowires
Physicists have used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly conductive man-made material.

7:46 AM | Doing Elitism Wrong
So, Katie Mack pointed me to this webcomic, which shows two characters stargazing. “I’m surprised more people don’t love science. It’s so fascinating.” “By science, do you mean spending countless hours collecting data and studying dense research articles? Or do you just think space is pretty?” OK. Let’s unpack the wrongness of this. (It’s been […]

7:05 AM | Understanding Quantum Tunnelling | Jon Butterworth | Life & Physics
Quantum tunnelling sounds like science fiction, and does indeed feature quite often in the genre. But it is real, and plays a role in nuclear fusion, chemical reactions and the fate of the universe. Heres how it worksThe recent claim from Stark Industries Lockeed Martin that a compact fusion reactor could be built soon is, if true, a breakthrough in engineering rather than basic physics. The basic physics of fusion has been known for some time, and a key element of understanding it is […]

9:32 PM | Hideout
Ad attirarmi sono stati innanzitutto i disegni: precisi e dettagliati, giocano moltissimo con i bianchi e i neri. Sono infatti opportunamente luminosi nelle scene cittadine, le più tranquille, e sono pesantemente bui nelle scene ambientate nel bosco o nella prigione sotterranea dove si trovano i protagonisti della vicenda, una coppia di giovani in crisi coniugale alla ricerca, apparentemente, di una soluzione ai loro problemi.In un fumetto dell'orrore, ad ogni modo, la parte grafica ha […]

9:24 PM | “It Should Have Been Obvious”
I can’t find my copy of The God Delusion. It wandered off to join the fairies in the Boston Public Garden, or something. This is only a problem when I’d like to look something up in it, to point to a passage and say, “Ah! If we’d read more carefully, we could have guessed that […]

4:32 PM | How to Communicate on the Internet
Let’s say you want to communicate an idea X. You would do well to simply say “X.” Also acceptable is “X. Really, just X.” A slightly riskier strategy, in cases where miscomprehension is especially likely, would be something like “X. … Continue reading →

9:13 AM | From Mindless Physics To Physics Of Mind
       For the sake of clarity, let us consider the two widely known, nonsensical scenarios: The first is one that many scientists charge ‘idealist’ philosophers with, although no thinker beyond the dorm room bong level holds this view: All is just a dream and there is no physical world. The second nonsensical scenario is that a physical world “really exists independently out there” and it happens to be the case that consciousness arises in […]

The two Fermi instruments have been surveying the high-energy sky since August 2008. The Large Area Telescope (LAT) has discovered more than a thousand new sources and many new source classes, bringing the importance of gamma-ray astrophysics to an ever-broadening community. The LAT catalog includes supernova remnants, pulsar wind nebulae, pulsars, binary systems, novae, several […]

9:09 PM | I macachi del giappone
Vi parlerò di due isole, Kojima, la più grande, e Torishima, per metà nascosta dietro l'altra. Entrambe ospitano branchi di macachi selvatici. Ci fu un tempo in cui l'intera isola di Kyushu pullulava di queste scimmie, tuttavia in seguito all'invasione dell'uomo ne sono rimasti solo pochi gruppi sporadici, perlopiù su isolette remote come queste. Le scimmie locali sono le meno influenzate dall'uomo e, in quanto tali, oggetto di studi approfonditi da parte dei […]

6:39 PM | Grassroots Campaign to get a Physics Nobel for Vera Rubin
Now that the 2014 Nobel Prizes are done, it's time to start looking forward to next year. Why so soon? Because I'm hoping that we can start a grassroots campaign to help Vera Rubin win the physics Nobel in 2015. The nominating process for 2015 began in September and ends in February 2015. So the time to make some noise is now!Please like the Facebook page lobbying for Vera Rubin's prize next year. In case you haven't heard of Rubin, she made the first compelling discovery that implies the […]
