Galindo-Uribarri and co-workers chose an isotope of neon with an energy structure that prevents it from emitting protons one at a time. This means that the two protons are certainly ejected simultaneo...
“We know that cosmic radiation at aircraft altitudes is several orders of magnitude more intense than that experienced at ground level because there is less protection from our atmosphere”...
The Poisson’s ratio of a material is defined as nij = –ej/ ei, where ej is the lateral strain in the j direction that is caused when a strain ei is applied in the longitudinal i direction....

When Victor Hess discovered cosmic radiation almost 90 years ago, he did so in manned balloon flights that reached altitudes of up to 5 km in the Earth’s atmosphere. This was only a few years af...
In 1967 Davis, then at the Brookhaven National Lab, built the first experiment to detect neutrinos produced by the Sun. Neutrinos only interact weakly with matter and are extremely difficult to detect...
Confirmation that the universe is flat – expanding at just the right rate not to collapse – came from measurements of ripples in the cosmic background radiation left over from the big bang...
