Altitude locates us in a relative position in respect to the surface of our planet. It therefore addresses fundamental questions such as ground and gravity and presents a precise framework for a conscious process of designing an architectural tectonic proj ...
Pamphlet Vol. 01 presents the Fall 2007 semester-course held by the studio ALICE at EPFL. Its content documents explorations on gravity and its direct implications in the conception of an architectural project, in this case for a pavilion for the London Fe ...
We suggest a new efficient way to constrain a certain class of large scale modifications of gravity. We show that the scale-free relation between density and size of dark matter halos, predicted within the ACDM model with Newtonian gravity, gets modified i ...
Since human behavior and perception have evolved within the Earth's gravitational field, humans possess an internal model of gravity. Although gravity is known to influence the visual perception of moving objects, the evidence is less clear concerning the ...

The porous medium model of Green and Ampt, describing flow in porous media, appeared earlier than the capillary model of Washburn, although both lead to the mathematically identical models. The model of Green and Ampt is related to the Washburn model by an ...
The accuracy and precision of current atom-interferometric inertialsensors rival state-of-the-art conventional devices using artifact-based test masses . Atomic sensors are well suited for fundamental measurements of gravito-inertial fields. The sensitivit ...
Two approaches have traditionally been used to describe the widening rate of jets and plumes: the diffusion concept of Prandtl, and the entrainment principle of Morton, Taylor and Turner. The entrainment concept is based on depth-averaged flow scales, and ...
We study whether a violation of the null energy condition necessarily implies the presence of instabilities. We prove that this is the case in a large class of situations, including isotropic solids and fluids relevant for cosmology. On the other hand we p ...
The dynamics of large fractal colloid aggregates, which were described by a combination of translational and rotational diffusion and internal elastic fluctuations, were investigated. Light scattering was used to measure dynamics of colloidal aggregates fo ...
The model of Dvali, Gabadadze, and Porrati (DGP) gives a simple geometrical setup in which gravity becomes 5-dimensional at distances larger than a length scale lambda(DGP). We show that this theory has strong interactions at a length scale lambda(3) simil ...
