4:00 AM | Experiment Provides the Best Look Yet at 'Warm Dense Matter' at Cores of Giant Planets
In an experiment at the Department of Energy's SLAC National Accelerator Laboratory, scientists precisely measured the temperature and structure of aluminum as it transitions into a superhot, highly compressed concoction known as “warm dense matter.”

4:27 PM | Zio Paperone e la grande avventura dell'acqua
Oggi, in occasione della giornata internazionale dell'acqua (leggi anche OggiScienza), recupero un estratto (modificato) di un post dedicato alla storia Zio Paperone e la grande avventura acquatica di Valentina Camerini e Marco MazzarelloI protagonisti della storia sono Archimede Pitagorico accompagnato da Paperone e da Paperinik. I tre paperi, mentre stanno rimpicciolendo alcuni iceberg, vengono per sbaglio ridotti a dimensioni atomiche dall'ultima invenzione di Archimede, riducendosi fino […]

4:21 PM | I marmocchi di Agnes
Durante le mie vacanze estive ho girato poco per librerie. Anzi, purtroppo sono andata in libreria solo due volte, delle quali una molto veloce. Però, nel mio primo giro, oltre un libro per bambini, ho acquistato due libri anche per me, uno dei quali è il seguito di "Agnes Browne mamma". La curiosità di sapere come sono continuate le vite della famiglia Browne era troppo grande!Agnes Browne ha continuato la sua vita di mamma/papà e venditrice di frutta e verdura al […]

Topics: Consumer Electronics, Economy, Electrical Engineering, Jobs, Nanotechnology, Materials ScienceTECHNOLOGY REVIEW: Diamond films are among the most extraordinary materials on the planet. They are strong, transparent and they conduct heat well. They are biologically inert but can also be chemically functionalised by attaching molecules to their surface. What’s more, when doped, they become semiconductors and so can be used in electronic circuits.So it’s no wonder that materials […]

4:00 AM | Probing the Fundamental Nature of Spacetime with the Renormalization Group
Renormalization group methods are a key element of theoretical particle physics and may also be central for constructing a fundamental theory of gravity, e.g., based on Weinberg’s asymptotic safety conjecture. The aim of this program is to bring together theorists and phenomenologists in order to discuss ideas related to the application of the renormalization group … Continue reading Probing the Fundamental Nature of Spacetime with the Renormalization Group →

1:00 AM | Thermodynamics with Continuous Information Flow
guest post by Blake S. Pollard Over a century ago James Clerk Maxwell created a thought experiment that has helped shape our understanding of the Second Law of Thermodynamics: the law that says entropy can never decrease. Maxwell’s proposed experiment was simple. Suppose you had a box filled with an ideal gas at equilibrium at […]

11:08 PM | Superconducting Electrons as a Frictionless Superfluid
While doing research for an article I'm writing about Janet Tate and her Gravity Probe B experiment[4], I found a few cool things regarding superconductors, frictionless bearings, and the Egg of Columbus experiment this morning.The Egg of Columbus demonstration was first performed by Nicola Tesla in 1893 at the World's Columbian Exposition[1].  Here's a brief video from MIT showing a modern day version of the demonstration[2]: The MIT site[2] describes the apparatus as follows: "A toroid […]

6:27 PM | Physics Life Hack Number 1 - Hack Your Eyes
Mathlete sees clearly with this physics life hackA simple trick can help you see clearly  - with physics!Age has not been kind to my eyesight or my memory. That means that while I now need glasses to correct for the farsightedness of the increasingly inflexible lenses in my eyes, I often forget where I put them (the glasses, not my eyes). That can be a real problem for someone whose entire job consists of reading.Fortunately, we at Physics Buzz would like to share a life hack for all the […]
