10:56 AM | I naufraghi del tempo
L'Editoriale Cosmo recupera una nuova serie classica della fantascienza a fumetti francese, "Inaufraghi del tempo" di Jean-Claude Forest e Paul GillonCi sono tutti gli elementi per rendere la saga fantascientifica di Jean-Claude Forest e Paul Gillon una parodia in stile Guida galattica. Il protagonista, Chris Cavallieri, è un uomo del XX secolo che ha dormito per mille anni fino a risvegliarsi in un futuro al tempo stesso alieno per tecnologia e familiare per intrighi. I suoi avversari […]

10:22 AM | Elemental 2D analogues of graphene: silicene, germanene, stanene, phosphorene
A comprehensive analysis of the fundamental properties, synthesis approaches and the future prospects of silicene, germanene, stanene, and phosphorene. It covers the literature on the fundamental properties of graphene analogous elemental sheets, inclusive of both theoretical and experimental knowledge. Various bottom-up synthesis techniques and top-down exfoliation approaches for the fabrication of two-dimensional elemental sheets are discussed.

10:06 AM | A spoonful of sugar in silver nanoparticles to regulate their toxicity
The use of colloidal silver to treat illnesses has become more popular in recent years, but its ingestion, prohibited in countries like the U.S., can be harmful to health. Scientists have now confirmed that silver nanoparticles are significantly toxic when they penetrate cells, although the number of toxic radicals they generate can vary by coating them with carbohydrates.

8:00 AM | Transformers, not by Michael Bay
Mathematically Precise Kinetic Sculptures and Transformable Objects by John Edmark I was a tad confused at first, because to me “kinetic sculpture” refers to those systems where balls are continually moving about on various tracks in a closed system. But these are rather nice, too.

7:53 AM | The slow dance that made you
We owe our origins to the stars. But it’s not the fast catastrophes that made us possible, but a slow, burning romance.Continue reading on Medium »

4:00 AM | Una ‘corsa interstellare’ contro il tempo
Un gruppo di astronomi hanno misurato la deformazione dello spaziotempo relativa al campo gravitazionale prodotto da un sistema stellare binario, prima che una delle due componenti, una pulsar, che si sta dissolvendo velocemente a causa di un fenomeno noto come precessione geodetica, scompaia dalla vista.  Denominata con la sigla J1906+0746, una ‘corsa interstellare’ contro il tempo, … Continue reading Una ‘corsa interstellare’ contro il tempo →

3:36 AM | Relativity, Cosmic Expansion, and the Big Bang
(Continuing from “The Expanding Universe.”) The expansion of the universe was also a vindication of Einstein’s theory of gravity, general relativity. Although it wasn’t understood at first, general relativity predicted either an expanding or contracting universe. A static universe of constant size, neither growing nor shrinking, would be unstable, like a carefully balanced upside-down pendulum. […]

8:26 PM | Your Smartphone Can Do Physics
That smartphone you carry around in your pocket all day is a pretty versatile lab assistant. It is packed with internal sensors that measure everything from acceleration to sound volume to magnetic field strength. But I'll wager most people don't realize what their phones can actually do.Screenshot from AndroSensor.Apps like SensorLog (iOS) or AndroSensor (Android) display and record raw data from the phone's movement, any background noises, and even the number of satellites in the […]

4:45 PM | Telescopio a rifrazione
Un telescopio a rifrazione o telescopio rifrattore è un tipo di telescopio ottico che utilizza una lente come obiettivo per formare un'immagine. Il progetto del telescopio a rifrazione fu originariamente utilizzato per i telescopi da terra e quelli astronomici. Sebbene i grandi telescopi rifrattori erano molto popolari nella seconda metà del XIX secolo, per la maggior parte degli scopi di ricerca sono stati sostituiti dai telescopi a riflessione che permettono aperture più […]

4:29 PM | Le superstringhe spiegate da Don Lincoln
Qualche tempo fa, ho pubblicato un post sulla teoria delle stringhe che, secondo uno studio proposto da due ricercatori della University of South California (USC) potrebbe rappresentare il punto di partenza di tutte le leggi della fisica (post). La ricerca degli elementi fondamentali della natura è uno degli scopi più antichi di tutta la fisica. Mentre siamo ancora … Continue reading Le superstringhe spiegate da Don Lincoln →
