7:00 AM | Nuovi indizi sulla nascita del Sole
Alcuni ricercatori della Monash University hanno condotto una serie di studi allo scopo di ricavare nuovi indizi sulle fasi primordiali del Sistema Solare e sugli eventi che hanno portato alla nascita del Sole. Gli scienziati, guidati da  Maria Lugaro  e Alexander Heger, hanno utilizzato la tecnica del decadimento radioattivo applicata ai nuclei atomici trovati nelle meteoriti […]

2:02 AM | More Tensor Index Identity Proofs: EM II Notes 2014_08_18
Summary:  Having worked through the examples that looked the most difficult, today's notes contain examples that are pick-up work from the easy problems.  These are simple-ish tensor index identities, including the divergence of the position vector, the cross product of the position vector, the Laplacian of one over the displacement squared, and the curl of a gradient.$\nabla \cdot \vec{r} = 3$$= \dfrac{\partial}{\partial x_i} r_i$Keep in mind that $r_1 = x$, $r_2 = y$, and $r_3 = z$.

1:33 AM | Slow Magnet Cooling Hose Hookup: Lab Book 2014_08_18
I’m working on attaching the cooling hoses to the iron yoke magnet today.  I attached the outlet hoses and ran a quick test to make sure that I did indeed have the outlet hose connections.  I attached a water bottle on a hose to the open connection pointed at in the picture below and forced water through.  The water exited at the labeled water out connection.  The exit connection will ultimately have a green hose on it like the manifold on the left.  Do not […]

12:15 AM | Engineering, lego and line followers
In the last few weeks I've been working with some second-year software engineering students on a design project. Their particular task is to build (with Lego - but the high-tech variety) a robot that can follow a white line on a bench. It's fun to watch them play with different ideas and concepts - there's the occasional disaster when the robot roars off at high speed in an unexpected direction and falls off the bench top.  To produce something that approximately works isn't that […]

9:26 PM | Evidence-based medicine actually isn’t
ContextClinical Trials,Biomedicine,Numbers by Tom Siegfried 5:28pm, August 18, 2014 In medical practice, the concept of evidence shares a lot with Saint Augustine’s understanding of time.He understood time perfectly well, of course, until somebody asked him to explain it. Medical evidence is similar. Everybody thinks they know what evidence means, but defining what counts as evidence is […]

8:24 PM | Researchers inspired by marine life to design camouflage systems
Researchers have developed a technology that allows a material to automatically read its environment and adapt to mimic its surrounding. The system is inspired by the skins of cephalopods, a class of marine animals which can change coloration quickly, both for camouflage and as a form of warning.

7:57 PM | Autostop con Buddha
La letteratura di viaggio è, si sa, il racconto di un'avventura vissuta realmente, perché in fondo ogni viaggio è un'avventura. Quando poi, come nel caso di Will Ferguson il viaggio è in un paese straniero, in una cultura ignota, il viaggio diventa un'avventura anche quando si svolge in un paese avanzato come il Giappone.Will era andato in Giappone per lavoro (insegnante) e decise di passare le proprie ferie a girare per il paese, in pratica da sud a nord, rischiando […]
