(1) MR- CANDLEK'S two volumes upon atomic spectra will appeal to the spectroscopist rather than to the general reader. As the title implies, the whole work is developed on the vector model of the atom ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

A theoretical study accepted by Physical Review Letters predicts that gravitational waves, the faint ripples in spacetime produced by colliding black holes and neutron stars, can leave detectable ...

Shifting lines: has the Higgs affected this spectrum? (CC-SA BélaBéla) A new way of measuring how the Higgs boson couples to other fundamental particles has been proposed by physicists ...

Balloons filled with hydrogen and containing metal salts are ignited. When the balloon explodes, the characteristically colored flame for that metal is seen. This is best performed outside or in a ...
