2:50 PM | Northern lights 14./15.10.2014
Last night there was a wonderful display of northern lights that was observed all over Finland! I was observing this natural display in Kuusamo, Northeastern Finland. It’s already winter here in Kuusamo, we have about 5 cm of snow on the ground and temperature was 10 degrees below zero! So the weathe was a bit […]

Alder Koten InstituteFrom the beginning of the month, I quote the post Mes de la Herencia Hispana:"The irony: in a country of immigrants, we're becoming "tribal"; somehow E pluribus unum: out of many, one - has lost its original Latin origins and just become a slogan printed on our money - if we ever bother to look at it."'Self-deportation' and repatriation as some have suggested would be a logistical and political nightmare that the global economy would immediately reject us as incompetent and […]

11:12 AM | L’ultima ‘rapida’ inversione del campo magnetico terrestre
Cosa succederebbe se, un giorno, ci accorgessimo che l’ago della bussola punta a Sud invece che a Nord? In realtà, non è poi così tanto strano come può sembrare perchè il campo magnetico terrestre si è invertito più volte nel corso della storia del nostro pianeta. Il campo magnetico di dipolo, analogo a quello di una […]

11:00 AM | Z Machine and Nuclear Fusion...
SANDIA NATIONAL LABORATORIESScientists are reporting a significant advance in the quest to develop an alternative approach to nuclear fusion. Researchers at Sandia National Laboratories in Albuquerque, New Mexico, using the lab’s Z machine, a colossal electric pulse generator capable of producing currents of tens of millions of amperes, say they have detected significant numbers of neutrons—byproducts of fusion reactions—coming from the experiment. This, they say, demonstrates […]

9:59 AM | Original Recipe
Relativity and Baseball Going back to the original idea of relativity — simply looking at the relative motion between objects, and the idea that you are allowed to look at the physics in the reference frame that makes the analysis the easiest. The other thing [besides analyzing momentum] you can do is to invoke relativity [...]

4:00 AM | La distribuzione di materia scura nella Via Lattea risulta ‘dimezzata’
Una serie di misure realizzate da un gruppo di astronomi australiani sulla distribuzione della materia scura nella Via Lattea suggeriscono che ne esiste circa il 50 per cento in meno rispetto a quanto si pensava in precedenza. Gli scienziati hanno usato un metodo sviluppato quasi 100 anni fa per stimare il contributo della materia scura nella nostra galassia: i […]

6:34 PM | Future computers could be built from magnetic 'tornadoes'
Magnetic materials form the basis of most hard disc drives as they are able to store data. Engineers have been investigating whether they could also be used to perform calculations, and so take on the role of a computer's central processing unit (CPU).

6:24 PM | Robot Sand Snakes
If you had no arms and no legs, just how would you propose to climb up a hill? Slither straight up like a snake? Ah, but what if the hill were made of sand?Physicists have unlocked the mystery by studying the mesmerizing motion of sidewinder rattlesnakes on sandy inclines and successfully mimicking this motion in a robot snake nicknamed 'Elizabeth'.The robot snake developed by researchers at Carnegie Mellon University climbs a tree. With modifications inspired by the wave motion in sidewinder […]
