Abstract Dark energy, or the cosmological constant Lambda, was introduced by Einstein in 1917, to describe a model of a static Universe. Wolfgang Pauli soon tried to interpret it as the energy of the quantum vacuum, extrapolated to the Universe, but found …

Exceptionally, the lecture takes place on Tuesdays. Abstract The complex structure of the Kuiper Belt suggests that the primordial disk of planetesimals was sculpted by irreversible orbital changes of the giant planets. Once the gas in the disk has …

Abstract Although atmospheric composition has varied over very long time scales, today's atmosphere is essentially made up of nitrogen ( N2 ) and oxygen ( O2 ). The impact of human activity on the concentration of these gases is measurable but negligible. …
