2014 Nobel Prizes in Physics and in Chemistry
by L. Bergé
During the second week of October 2014, the Swedish Academy of Sciences decided to award two practical inventions, blue Light Emitting Diodes (LEDs) and super-resolved fluorescence microscopy, with the 2014 Physics and Chemistry Nobel Prizes.
Showering from high-energy cosmic rays
by H. Buisman, D.Wilke de Souza and J. Steijger
In particle physics a ‘shower’ is the avalanche of secondary particles produced by an incoming particle with high energy. This production requires the interaction with mass. A shower produced by high-energy cosmic rays usually covers a wide area, of the order of a square kilometer. The secondary particles can be observed by using scintillators. In view of the large area affected and the relatively simple equipment needed, this is an ideal project to involve high-school students and their teachers. Showering can also be observed in doors, on much smaller scale.
Consumer participation in power market balancing
by P. Lund
With the increasing role of wind and solar power, the power balance authorities are facing a big challenge: How to manage the increasing need for the fast balancing of power brought on by increased penetration of variable and difficult-to-forecast renewable generation? Could more active participation by the residential customers in managing electricity demand be a smart way to go?
Extra-terrestrial Life in the Milky Way Galaxy?
by N.J. Evans II
Are we alone? Along with questions about black holes, this is one of the questions most commonly asked of astrophysicists. While the simple answer is that we don’t know, logical and rational exploration of the question can be illuminating and a very good way to introduce non-scientists to the “scientific worldview.” This short essay is based on a class for students not majoring in science, which I have taught for nearly forty years at the University of Texas at Austin.
A new publication frequency for EPN
Victor R. Velasco, EPN Editor
At the 2014 EPS Council meeting it was decided to reallocate some funds to finance EPS activities in Brussels. For EPN this means that, for 2014 and 2015, the last two issues will be merged into one 48-page issue (5&6, published in November), which saves distribution costs. As you may have noticed already, there is now also a flip book pdf version with an html version that is indexed by Google. This user-friendly flip book will be available for all issues (see: http://www.zyyne.com/widgetdoc;13732).
