10:21 PM | Spin and the Stern-Gerlach Experiment
Spin and the Stern-Gerlach Experiment The word “quantum” means a single share or portion. In quantum mechanics, this means that energy comes in discrete chunks, or quanta, rather than a continuous flow. But it also means that particles have other properties that are discrete in a way … Continue reading → The post Spin and the Stern-Gerlach Experiment appeared first on The Physics Mill.

4:11 PM | Of tree rings and rain: droughts predicted to worsen in southwestern United States
Droughts have intensified in already dry regions around the world, including in the Southwest United States and in Australia throughout the first decade of this century.  The severity of these droughts has been attributed to global warming and climate change, which … Continue reading →

9:03 AM | Il (non) carnevale della fisica #6
Iniziamo con quello che è il piccolo evento del mese: i 25 anni della mitica foto Pale Blue Dot, ovvero la foto scattata scattata dalla Voyager il 14 febbraio del 1990. A questo mitico puntino Carl Sagan ha dedicato un bellissimo commento, che Amedeo Balbi ha pubblicato in uno dei suoi primi post su Keplero: Siamo riusciti a fare questa foto: se la guardate, vedete un puntino. Quello è qui. Quella è casa. Quelli siamo noi. Ogni persona che amate, che conoscete, di cui […]

3:01 PM | Experiencing the modern city
Of all the things that have had a persistent tendency to surprise observers, cities have been among the most prolific. Then again, they’d better be for all their social and economic complexity, for their capacity to be the seed of so many perspectives on human development. We shape our cities, which then shape us, and we shape […]

2:50 PM | What goes on inside a proton? | Jon Butterworth | Life & Physics
Quarks and gluons make weird slopes and shapes inside the proton. Understanding them precisely was important for the first results from Cern’s Large Hadron Collider, and continues to be so as we approach the restart over the next few weeksI spent part of last week at a meeting in the Pyrenees, northern Spain, discussing the internal structure of the proton. The meeting was in the small village of Benasque, hosted by Juan Rojo at the Centro de Ciencias de Benasque Pedro Pascual. The proton […]

9:49 AM | Virginia Trimble on Pyramids and Missing Extraterrestrials
Did you ever wonder if there was any 'real science' behind the subject matter of shows like 'Ancient Aliens'?  There is!  Yesterday I came across these two articles[1][2] by Dr. Virginia Trimble: UC Irvine astronomy professor and science historian.  The first article was written by Dr. Trimble when she was still an undergrad at UCLA.  It detailed her calculations showing that the constellation Orion was visible through the 'so called air shaft' of Cheops pyramid when it was […]

A long-anticipated interdisciplinary field of science is now exploding on the scene: Astrobiology. Are habitable planets common in the universe? What properties of a planet are necessary for chemical reactions to create replicating molecules such as DNA, to spawn biology and support long-term evolution?   The NASA Kepler Mission has discovered hundreds of Earth-size planets in … Continue reading Worlds Suited for Biology →

4:00 AM | Baryons at low density: stellar halos around galaxies
Stellar halos are ubiquitous in luminous galaxies, but because of their faint surface brightness the detailed study of their physical properties has been difficult and, until recently, confined largely to the Milky Way (MW) and Andromeda. Since the advent of large cameras and surveys, both from ground and space, our knowledge of stellar halos is … Continue reading Baryons at low density: stellar halos around galaxies →
