3:03 PM | Chandra Science on State Street
Hundreds of explorers converged on the campus of Framingham State University in Massachusetts on Saturday, April 25, 2015 to take part in the first annual Science on State Street festival. The family-focused event offered up a variety of interactive STEM-themed learning stations addressing aspects of chemistry, astronomy, biology, engineering, robotics and more, arranged outdoors across the University’s shady upper campus. We estimate between 500 and 600 visitors overall to the event. […]

1:53 PM | Scivolare lungo un piano inclinato
Scrive Jacopo Cirillo a proposito di Stephen KingSemplificando in maniera orrendamente antiscientifica, se prendiamo un piano inclinato e una biglia e facciamo scorrere la biglia sul piano inclinato, la stessa biglia accelererà sempre di più e, se il piano inclinato è lungo all'infinito, la biglia accelererà all'infinito fino a diventare, non so, velocissima. Ma c’è un inghippo: la superficie del piano, di solito, è scabra, ovvero subisce […]

12:48 PM | IBM scientists achieve critical steps to building first practical quantum computer
IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum errors simultaneously, as well as demonstrated a new, square quantum bit circuit design that is the only physical architecture that could successfully scale to larger dimensions.

Shiva. Image Source: Hiroshima Poetry, related to the embed belowTopics: Existentialism, Manhattan Project, Nuclear Physics, Nuclear PowerHaving lived through the "duck-and-cover" drills of the sixties and seventies (for me at least), the fact we don't do them anymore doesn't reduce the existential danger. We have the unique position in species of intelligence on this Earth, a way - as Carl Sagan would have said - for the Cosmos to "know itself." We're also the only species that could take the […]

4:00 AM | La mappa 3D dell’Universo locale
Gli astrofisici dell’University of Waterloo hanno creato una mappa tridimensionale finora la più completa dell’Universo locale che si estende per quasi 2 miliardi di anni-luce. Questa mappa sferica, decisamente innovativa, che mostra la distribuzione dei superammassi vicini permetterà agli scienziati di capire ancora meglio come è distribuita la materia scura nello spazio e di ricavare … Continue reading La mappa 3D dell’Universo locale →

9:44 PM | Messing up the test: the next installment
In the last few years I've been experimenting with the way I test our 3rd year mechanical engineering students in their 'Dynamics and Mechanisms' paper. I've chosen this paper because (a) it has more than a handful of students, and (b) I am in charge of it. When  I've suggested to my peers that I do something similar with other papers I teach on (but not in charge of) a "Don't you dare" tends to ring out rather clearly in response. So Dynamics and Mechanisms it has to be.  I've […]

Plaque-busting nanoparticles could help fight tooth decayNanotechnology might soon save you a trip to the dentist. Researchers have developed tiny sphere-shaped particles that ferry a payload of bacteria-slaying drugs to the surface of the teeth, where they fight plaque and tooth decay on the spot. The approach could also be adapted to combat other plaquelike substances, known as biofilms, such as those that form on medical devices like orthopedic implants.Read the rest of my story of Science

8:36 PM | We should do more to more about our digital memories | Life & Physics
On bit rot, Donkey Kong and and old photographsRecently I rescued some data from an old laptop with a broken screen and a failing disk drive. It was a very emotional experience.This isn’t physics data. These are megabytes of music not petabytes of particles. Actually they are the songs I downloaded when my son was very small, and I used to dance him to sleep in front of the big mirror in our living room. He would look over my shoulder at himself, and at me, with his big brown eyes, and I […]
