8:00 AM | A Visit to the Museum of Osteology
I knew what I expected from the Museum of Osteology in Oklahoma City: amusement. I go to a lot of museums, and in my experience, privately-run museums based on one person’s obsession are always quirky and often pretty fun. This museum was founded by a guy and his wife who have a business next door […]

4:00 AM | Posto un limite al grado di ‘confusione’ dello spaziotempo
In occasione del centenario della relatività generale, un gruppo internazionale di ricercatori, hanno proposto un nuovo esperimento per verificare le previsioni della teoria di Einstein. In un articolo pubblicato su Nature Physics, essi descrivono il loro studio relativo ad una delle assunzioni base della teoria: il fatto, cioè, che tutte le particelle di luce, meglio … Continue reading Posto un limite al grado di ‘confusione’ dello spaziotempo →

1:06 AM | Astroquizzical: Do all planets rotate in orbit around their stars? (Synopsis)
When you think about our world and our place in the Solar System, you very likely think about Earth, spinning on its axis, with the Moon orbiting around it, and with the entire Earth-Moon system orbiting the Sun. But did you know that all of it — the Earth spinning on its axis, the Moon revolving around…

4:17 PM | BA Video: Attack of the Waterspout!
A couple of weeks ago, a waterspout formed off the coast of a tropical beach in Brazil. The panic it evoked was merited … kinda sorta. Here’s why: I’ve seen dust devils in person many times (driving from California to Colorado years back, we saw a half dozen, one that was so big we were kilometers away when we first spotted it), and pictures of them on Mars(!). But I’ve never seen a tornado in the wild myself, or a waterspout … or an ash devil, or a fire […]

11:00 AM | The Top of the World Sinks Ever Lower
Ever year around the end of February, after a long winter, Arctic ice reaches its maximum extent. This year that happened around Feb. 25, when it encompassed 14.54 million square kilometers of ice around the North Pole. Sound like a lot? It’s not. Really, really not. This year’s maximum extent was the lowest on record. The plot above shows the situation. The solid line shows the average ice extent over the year (measured from 1981–2010) and the gray area represents a […]

The other day I was just starting to work when I heard a strange cooing in the other room. It sounded like a baby. But I swore I’d just dropped the actual baby off at a friend’s house. When I went to investigate, the baby wasn’t there, so I figured I was having a mild, […]

4:00 AM | Il nostro Universo fa parte di un Multiverso?
Il modello dell’inflazione cosmica, pubblicato da Alan Guth nel 1981 su Physical Review D, e di cui ha scritto successivamente un libro, fornisce una spiegazione alquanto plausibile su diverse proprietà dell’Universo, tra cui la sua uniformità (vedasi principio cosmologico), la sua densità di massa e la radiazione cosmica di fondo. Molte versioni dell’inflazione implicano che il … Continue reading Il nostro Universo fa parte di un Multiverso? […]
