Webster's Universal Spanish-English Dictionary, the Graphical Law and A Dictionary of Geography of Oxford University Press

Comments: 27 Pages. A mistake in plotting BW(c=0.01) has been rectified

We study the Webster's Universal Spanish-English Dictionary by Geddes and Grosset. We draw the natural logarithm of the number of entries, normalised, starting with a letter vs the natural logarithm of the rank of the letter, normalised( unnormalised). We conclude that the Dictionary can be characterised by BP(4,βH=0) i.e. a magnetisation curve for the Bethe-Peierls approximation of the Isingmodel with four nearest neighbours in absence of external magnetic field. H is external magnetic field, β is 1/(k_B T) where, T is temperature and k_B is the Boltzmann constant. Moreover, we compare the Spanish language with two other Romance languages, the Basque and the Romanian languages respectively. On the top of it, we compare the Spanish-English Dictionary with A Dictionary of Geography of Oxford University Press by Susan Mayhew and find a tantalizing similarity between the Spanish and the jargon of Geography.

Can Frozen Hydrogen Snowballs Account for Galactic Dark Matter

Comments: 16 Pages. Poster presented at American Physical Society virtual meeting March 2021 [Corrections are made by viXra Admin to comply with the rules of viXra.org]

•DARK MATTER: Most mass in galaxies is invisible –what is it? •>80% of matter lies in halo around galaxies, but not in stars or other visible objects. •Cannot be dilute gas of H2and He –absorption lines would appear in spectra. •Popular theories suggest novel particles or novel dark objects such as black holes.

•Simpler alternative: frozen H2snowballs at 2.7 K. •Could also trap most He atoms internally. •This model could be tested using a cryogenic laboratory experiment.

•Classical superconducting circuit simulators are powerful and available. •Include Josephson junction as basic element. •Provide efficient time-domain simulations of complex circuits. •May show effects otherwise attributed to quantum circuits.

•Circuits of coupled superconducting qubits are being developed for quantum computing (QC). •Entangled quantum theory incompatible with classical simulators. •Quantum model difficult to simulate on conventional computers for complex circuits already being tested. •Classical circuit simulations should provide the baseline to compare with quantum effects, but this is seldom done. •Coupled oscillators are delocalized even in classical limit.

Ultra-Conductive Magnesium

Authors: Fran De Aquino
Comments: 4 Pages.

The improvement of the electrical conductivity of usual metals is limited by the purity of the metal and the ability to grow single crystal structures. Also, it was observed that the AC conductivity of the metal increases when the frequency of the electrical current applied on the conductor increases. Here, we show that the pure Magnesium metal can exhibit an ultrahigh electrical conductivity when it is subjected to 360K temperature, and an electrical current with frequency of the order of 1GHz.
