Nature(Oct 20, 2016) Quantum physics has had an impressive record of predictive success, ranging from quantum chemistry to elementary particle physics. Nature(Oct 04, 2016) On 1 September, researchers at the UFRJ’s Laboratory of Elementary Particles petitioned Brazil’s justice, science and education ministries to release Hicheur.
