Galileo Galilei

Galileo Galilei and the property of naming light spots.

Galileo's eye: a new vision of the senses in the work of Galileo Galilei.

Reflections on the senses, and particularly on vision, permeate the writings of Galileo Galilei, one of the main protagonists of the scientific revolution. This aspect of his work has received scant attention by historians, in spite of its importance for his achievements in astronomy, and also for the significance in the innovative scientific methodology he fostered. Galileo's vision pursued a ...

`-conformal Galilei algebras

Inequivalent N = 2 supersymmetrizations of the `-conformal Galilei algebra in d-spatial dimensions are constructed from the chiral (2, 2) and the real (1, 2, 1) basic supermultiplets of the N = 2 supersymmetry. For non-negative integer and half-integer ` both superalgebras admit a consistent truncation with a (different) finite number of generators. The real N = 2 case coincides with the supera...

Deformed Galilei symmetry

A particular deformation of central extended Galilei group is considered. It is shown that the deformation influences the rules of constructing the composed systems while one particle states remain basically unaffected. In particular the mass appeared to be non additive.

Io after Galileo

Io, the volcanically active innermost large moon of Jupiter, was a target of intense study during the recently completed NASA Galileo mission to Jupiter (1989–2003). Galileo’s suite of instruments obtained unprecedented observations of Io, including high spatial resolution imaging in the visible and infrared. This paper reviews the insights gained about Io’s surface, atmosphere and space enviro...
