Antimatter trapped at CERN

Antimatter trapped at CERN. here is the press release and a summary form the source:

"The ALPHA experiment at CERN has taken an important step forward in developing techniques to understand one of the Universe’s open questions: is there a difference between matter and antimatter? In a paper published in Nature today, the collaboration shows that it has successfully produced and trapped atoms of antihydrogen. This development opens the path to new ways of making detailed measurements of antihydrogen, which will in turn allow scientists to compare matter and antimatter.

Antimatter – or the lack of it – remains one of the biggest mysteries of science. Matter and its counterpart are identical except for opposite charge, and they annihilate when they meet. At the Big Bang, matter and antimatter should have been produced in equal amounts. However, we know that our world is made up of matter: antimatter seems to have disappeared. To find out what has happened to it, scientists employ a range of methods to investigate whether a tiny difference in the properties of matter and antimatter could point towards an explanation."

Prueba sobre impaciencia ¿califica como tortura?

Ayer unos de mis alumnos expusieron sobre economía y psicología (o economía del comportamiento). En la exposición usaron varios videos uno de los cuales es particularmente cómico aunque también puede calificar como cruel. Acá pongo el enlace para que lo vean. El final es muy ilustrativo sobre como algunos compensamos el aguante.

Incomplete, badly named, biased, but still interesting

Dan Ariely's list of "new economists". Unfortunately only Fehr is outside the USA and in the list. Of course the list is incomplete (fill the places as you please). Someone else should have a good list on this, just for the public to know there is more to economics than the current crisis and stuff like that.
