In both European and non-European cities, public spaces are formed by racist and segregative politics that influence everyday life. Planetary migration flows and recently implemented border politics tend to leave the most vulnerable in precarious conditions, not only in the case of migrants/refugees but also in the case of citizens. This article focuses on how artistic methodologies in the contex...

The first public radio station in the United States, KPFA in Berkeley, California, began broadcasting in April 1949. A legendary counter-cultural enterprise, its initial program months aired a daily fifteen-minute performance of one of the most consequential literary works of late Modernist world literature, Jaime de Angulo’s ethnopoetic masterpiece Old Time Stories (announced as “Indian

In the mind of anyone who knew them and their work, the British art critic and curator Guy Brett and the Filipino mixed-media and performance artist David Medalla formed a pair. Which is why, though it might sound awful, I was not overly surprised by the news that Guy had died (February 2, 2021) just over a month after David (December 28, 2020). It was as if the former had waited for permission to...

This article gives a overall picture of how the universe works from the likelihood that our universe is infinite dimensional at the nanometer scale of an indestructible quark. The article explains that we only can perceive for sure up to 4 dimensions of physical reality. However, the speculation in this article seems very clear that likely we are seeing activity in the 5th dimension in particle ph...

A number of the most often cited results of relativity theory deal with the relationships between energy, momentum and inertial mass. The history of how Einstein and Planck came to these conclusions is reviewed. It is pointed out that considerations of how the speed of light is affected by the motion of the Earth played a determining role in these developments. After the Michelson-Morley null-inte...

The present, at any particular moment, is the realization of one of the many intentions of the All-creating Intellect. Here "realization" specifically means the materialization or the appearance of an object in the material world, which had not existed until now. This newly born material object exists only for the duration of the moment of "now". This moment is infinitely short, or, if we use a co...

It is widely believed that Hawking radiation originates from excitations near the horizons of black holes [1,2,3]. However, Giddings [2] proposed that the Hawking radiation spectrum that characterizes evaporating semi-classical black holes originates from a quantum “atmosphere”, which extends beyond the horizon of a black hole. Although several research projects have been conducted in this fie...

Neutron-rich Sr nuclei around N = 60 exhibit a sudden shape transition from a spherical ground state to strongly prolate-deformed. Recently, much new insight into the structure of Sr isotopes in this region has been gained through experimental studies of the excited levels, transition strengths, and spectroscopic factors. In this work, a “classic” shell model description of strontium
isotopes...

In this paper we consider the correspondence between the tachyon dark energy model and the Tsallis holographic dark energy scenario in an FRW universe. We demonstrate the Tsallis holographic description of tachyon dark energy in an FRW universe and reconstruct the potential and basic results of the dynamics of the scalar field which describe the tachyon cosmology. In a flat universe, in the tachyo...

The excitation cross-sections of the nS states of atomic hydrogen, n = 2 to 6, by electron
impact on the ground state of atomic hydrogen were calculated using the variational polarizedorbital method at various incident electron energies in the range 10 to 122 eV. Converged excitation
cross-sections were obtained using sixteen partial waves (L = 0 to 15). Excitation cross-sections to
2S state, ...
