Stellar flares seen from a nearby red dwarf star.

On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions was as much as 10,000 times more powerful than the largest solar flare ever recorded. At its peak, the flare reached temperatures of 360 million degrees Fahrenheit (200 million Celsius), more than 12 times hotter than the center of the sun. The "superflare" came from one of the stars in a close binary system known as DG Canum Venaticorum, or DG CVn for short, located about 60 light-years away. Both stars are dim red dwarfs with masses and sizes about one-third of our sun's. They orbit each other at about three times Earth's average distance from the sun, which is too close for Swift to determine which star erupted. See: NASA | Swift Catches Mega Flares from a Mini Star

Problems with Your Blog Page?

I have notice black areas appearing on my blog page when accessing site through my laptop. I am wondering if this is a problem that I am just experiencing or if others Are having the same issue?

When will the Compass Point South?

If all the compasses in the world started pointing south rather than north, many people might think something very strange, very unusual, and possibly very dangerous was going on. Doomsayers would have a field day proclaiming the end is nigh, while more rational persons might head straight to scientists for an explanation.See:When Compasses Point South also Nova and Interactive

Deep inside the Earth, the magnetic field arises as the fluid core oozes with hot currents of molten iron and this mechanical energy gets converted into electromagnetism. It is known as the geodynamo. In a car's generator, the same principle turns mechanical energy into electricity. No one knows precisely why the field periodically reverses, but scientists say the responsibility probably lies with changes in the turbulent flows of molten iron, which they envision as similar to the churning gases that make up the clouds of Jupiter. In theory, a reversal could have major effects because over the ages many aspects of nature and society have come to rely on the field's steadiness.See: Will Compasses Point South?-By WILLIAM J.

Particles in Peace

This was in May of 2013.

Yaron Herman plays piano jazz that is utterly unique. He learned to play based on a method using math and philosophy.

Bijan Chemirani, French-born percussionist, was initiated into the art of Iranian percussion by his father, Djamchid Chemirani, at an early age and has acquired enormous experience in adapting his playing style to other genres of music.

Here they perform together for the first time at TEDxCERN.

Latest Results of AMS

 (AMS) collaboration has today presented its latest results. These are based on the analysis of 41 billion particles detected with the space-based AMS detector aboard the International Space Station. The results, presented during a seminar at CERN, provide new insights into the nature of the mysterious excess of positrons (antielectrons) observed in the flux of cosmic rays. The findings are published today in the journal Physical Review Letters. See: New result from AMS experiment in Space|Cern

Ovation Aurora

The Space Weather Prediction Center and the Space Weather Prediction Testbed have introduced a new Auroral Forecast test product in an effort to improve services to current customers and expand our customer base with new products. The Auroral Forecast product is based on the OVATION Prime model which provides a 30-40 minute forecast on the location and probability of auroral displays for both the northern and southern polar regions. The development and implementation of this model has been a joint effort. The model itself was developed by P. Newell at the Johns Hopkins, Applied Physics Lab. Scientists at the NESDIS National Geophysical Data Center (NGDC) added further refinements to make the model run in real time. Researchers at the Space Weather Prediction Testbed validated the model and developed graphical displays. This model is driven by real-time solar wind and interplanetary magnetic field information from the Advanced Composition Explorer (ACE) satellite. The model is based on more than 11 years of data from the Defense Meteorlogical Satellite Program (DMSP) from which an empirical relationship between the solar wind conditions and the aurora location and intensity was developed.

Geant4 is a toolkit for the simulation of the passage of particles through matter. Its areas of application include high energy, nuclear and accelerator physics, as well as studies in medical and space science. The two main reference papers for Geant4 are published in Nuclear Instruments and Methods in Physics Research A 506 (2003) 250-303, and IEEE Transactions on Nuclear Science 53 No. 1 (2006) 270-278. See: Geant4

See: Applications 


Geant4 [1][2] (for GEometry ANd Tracking) is a platform for "the simulation of the passage of particles through matter," using Monte Carlo methods. It is the successor of the GEANT series of software toolkits developed by CERN, and the first to use object oriented programming (in C++). Its development, maintenance and user support are taken care by the international Geant4 Collaboration. Application areas include high energy physics and nuclear experiments, medical, accelerator and space physics studies. The software is used by a number of research projects around the world.
The Geant4 software and source code is freely available from the project web site; until version 8.1 (released June 30, 2006), no specific software license for its use existed; Geant4 is now provided under the Geant4 Software License.

Muon Tomography (cont)

It is the case of an article on Muon Tomography, titled New Muon Detector Could Find Hidden Nukes. The article appeared a few days ago on Wired. It is centered on Lisa Grossman's interview to Marcus Hohlmann, a colleague from the Florida Institute of Technology. In a nutshell, the article explains how muon particles from cosmic rays can be used to detect heavy elements (as in nuclear fuel) hidden in transport containers. And what makes things sexier is that the used technology is a spin-off from experiments from particle physics. See: Muon Tomography: Who Is Leading The Research ?

Beginning next year, two detectors (shown here in green) on either side of Fukushima Daiichi’s Unit 2 will record the path of muons (represented by the orange line) that have passed through the reactor. By determining how the muons scatter between the detectors, scientists will compile the first picture of the damaged reactor’s interior. See:
Particle physics to aid nuclear cleanup

The progression of Muon Tomography,  is an interesting subject in relation to what can be used to help us understand issues we face here on earth. Situations that need new ways in which to diagnostically deal with extreme situations. Example given in relation too, rock density, magma flows, or, even nuclear reactors.

One has to learn to understand "links that are dropped" which pursue a thread of evolution. These help one to understand the processional use of the technologies as used to understand the ways things are measured in those extreme situations. Sensor-ability,  then takes on a new meaning while using current scientific research and understandings in particle physics.

Interstellar: Traversing the Wormhole

The story has a premise with which to share an idea and if it is intriguing to the average mind, then how much more so when a scientist entertains it? He or she might even propose a way in which to use measure with regard to the subject of a black hole?:)
But later I found out more about wormholes, and learned about “topological censorship.” It turns out that if energy is nonnegative, Einstein’s gravitational field equations prevent you from traversing a wormhole — the throat always pinches off (or becomes infinitely long) before you get to the other side. It has sometimes been suggested that quantum effects might help to hold the throat open (which sounds like a good idea for a movie), but today we’ll assume that wormholes are never traversable no matter what you do. SEE: Entanglement = Wormholes

A group of explorers make use of a newly discovered wormhole to surpass the limitations on human space travel and conquer the vast distances involved in an interstellar voyage. Interstellar
