This invention describes a novel gravity-independent exercise unit designed for use in microgravity, or on the ground, as a means by which to counter muscle atrophy and bone degradation due to disuse or underuse. Modular resistive packs comprising constant torque springs provide constant force opposi...
while other realisations produce enough diffusion away from general relativity to be detectable by future table-top experiments. Although the absence of such deviations from general relativity would not be as direct a confirmation of the quantum nature of gravity, such as experiments proposed in refs...
A lead screw nut mechanism is designed to adjust the pretension force of the springs to balance the gravity for persons of different weights. The rest of this paper is organized as follows. In Section 2, the working principle of the new design is described in detail. This includes a design...
Possibly a few wild cards such as 'skip ahead' or 'fall down 2 spaces' 1 die Procedure Students will work in groups of 2-4. Be creative with the game boards and/or the description of the game. You could explain that all students are astronauts and have to work their way away from ...
As the density of materials currently available for such experiments varies within a range of only two orders of magnitude, the linear dependence on ρ sets a considerable restriction on the values that η can take. The densest naturally available material is Osmium, which has ρ = 22.59...
Enlightenment hegemony over the Western intellectual outlook, which can be summarized briefly as follows: that there exists an external world, whose properties are independent of any individual human being and indeed of humanity as a whole; that these properties are encoded in ``eternal'' physical ...
In orbital conditions the photopolymerization of polyacrylamide gel (PAG) was found to be developing as a frontal process in stagnant liquid. Terrestrial experiments and mathematical modelling have demonstrated the existence of convective flows and their strong influence both on structuration and on the ...
