In 1925, grad student Cecilia Payne first proposed that stars were mostly made of hydrogen and helium and shaped our ...

Designers at SverdNIIhimmash (part of Rosatom’s Mechanical Engineering Division) have received patents for a model of a press ...

Bryant Colwill, manager of the University at Albany’s College of Nanotechnology, Science, and Engineering’s Innovation Lab at Albany NanoTech, demonstrates a new plasma-enhanced atomic layer ...

In Bohr’s 1913 papers he envisaged atoms along the lines established by his mentor Ernest Rutherford: dense nuclei orbited by ...

In addition, Moseley's laws allow us to calculate very accurately the wave-lengths of the X-ray spectral lines for any element in the periodic table, if those of the elements in its neighbourhood ...
