Dimensionless Physics: Continuation
نویسندگان
چکیده
Several approaches to quantum gravity (including the model of superplastic vacuum; Diakonov tetrads emerging as bilinear combinations fermionis fields; BF-theories gravity; and effective acoustic metric) suggest that in general relativity metric must have dimension 2, i.e., [g??] = 1/[L]2, irrespective spacetime. This leads “dimensionless physics” discussed [1]. Here we continue exploit this unusual metric.

Dimensionless Monocular SLAM
It has recently been demonstrated that the fundamental computer vision problem of structure from motion with a single camera can be tackled using the sequential, probabilistic methodology of monocular SLAM (Simultaneous Localisation and Mapping). A key part of this approach is to use the priors available on camera motion and scene structure to aid robust real-time tracking and ultimately enable...
متن کاملDimensionless Fast Fourier Transforms
This paper shows that there are fast Fourier transform (FFT) algorithms that work, for a fixed number of points, independent of the dimension. Changing the dimension is achieved by relabeling the input and the output and changing the “twiddle factors.” An important consequence of this result, is that a program designed to compute the 1-dimensional Fourier transform can be easily modified to com...
متن کاملDimensionless units in the
The International System of Units (SI) is supposed to be coherent. That is, when a combination of units is replaced by an equivalent unit, there is no additional numerical factor. Here we consider dimensionless units as defined in the SI, e.g. angular units like radians or steradians and counting units like radioactive decays or molecules. We show that an incoherence may arise when different un...
متن کاملWhat if entropy were dimensionless?
One of entropy’s puzzling aspects is its dimensions of energy/temperature. A review of thermodynamics and statistical mechanics leads to six conclusions: ~1! Entropy’s dimensions are linked to the definition of the Kelvin temperature scale. ~2! Entropy can be defined to be dimensionless when temperature T is defined as an energy ~dubbed tempergy!. ~3! Dimensionless entropy per particle typicall...
متن کاملDynamic similarity, the dimensionless science
www.physicstoday.org Many experiments seem daunting at first glance, owing to the sheer number of physical variables they involve. To design an apparatus that circulates fluid, for instance, one must know how the flow is affected by pressure, by the apparatus’s dimensions, and by the fluid’s density and viscosity. Complicating matters, those parameters may be temperature and pressure dependent....
