A team of researchers from the University of Oxford, MIT and the University of Limerick has found that it is possible to predict the stability of a collapsing ring by counting its kinks. In their paper published in the journal ...
A new door to the quantum world has been opened: When an atom absorbs or releases energy via the quantum leap of an electron, it becomes heavier or lighter. This can be explained by Einstein's theory of relativity (E = mc2). ...
