A new way to improve how we measure the age of planetary evolution in our solar ... This allows researchers to reconstruct 3D atom scale models of the material, and visualise the extent of ...

much-maligned Bohr model of the atom. That's the one where electrons move about the atomic nucleus in circular orbits, like planets orbiting the Sun in our Solar System. The orbits have set ...

It was Rutherford's intuitive leap to a new 'planetary' model of the atom - where individual electrons orbit a solid central nucleus - that Graham Farmelo argues was one of the most profound ...
