Dark Side of the Trees

@menarddg

It was beginning winter, An in-between time, The landscape still partly brown. In a dark time, the eye begins to see, A lord of nature weeping to a tree, I meet my shadow in the deepening shade. How terrible the need for solitude: A man’s a beast prowling in his own house, A beast with fangs, and out for his own blood. It was beginning winter, The light moved slowly over the frozen field; The mind moved, not alone, but through the clear air in silence. I live near the abyss, and dream of death: The light air takes my being’s breath; When will that creature return it to me? My light is dark, and darker my desire: A fallen man, I climb out of my fear; Am I beast or Am I man? Elegiacal Poetry “Man’s a Beast” from Dark Side of the Trees ( 2002-2003) made at The Mel Hoppenheim School of Cinema & Film Studies, Concordia University, Cinema Dept., Montreal Quebec.

HOMEOMORPHICALLY IRREDUCIBLE TREES

Homeomorphically irreducible trees We can count homeomorphically irreducible trees by modifying the approach of Section 4.2. To apply Theorem 4.3, we need to count homeomorphically irreducible trees rooted at a vertex, at an edge, and at a vertex and incident edge. In a vertex-rooted tree, a child of a vertex v is a vertex adjacent to v that is farther from the root than v. Thus if v is the root,…

Toward a Complete Analysis of the Global Structure of Kerr-Newman Spacetime written by Hongsu Kim (Ewha Women's Univ., Korea)

An attempt is made to supplement Carter’s partial investigation of the global structure of Kerr-Newman spacetime on the symmetry axis. Namely, the global structure of \theta = const. timelike submanifolds of Kerr-Newman metric starting from the symmetry axis all the way down to the equatorial plane are studied by introducing a new time coordinate slightly different from the usual Boyer-Lindquist…

(Mac) Brazel, a rancher from approximately 75 miles northwest of Roswell, NM, contacted the local sheriff and reported that some metallic debris had come to rest on the ranch on which he worked near the town of Corona, NM. This was during the…

NEUTRINO COUNTER NUCLEAR WEAPON

THEORETICAL PREPARATION One of the properties of neutrino is that it has a vanishingly small interaction cross section so that it is the most penetrative radiation known to be in existence today. The invariant amplitude M is proportional to the weak boson (massive spin-1) propagator [4–6] −i(gμν −qμqν/M2), (1) q2 −M2 +iǫ where q is the transfer momentum, M is the weak boson mass and the…

Neutrino Counter Nuclear Weapon by Alfred Tang∗

Neutrino Counter Nuclear Weapon Alfred Tang∗ (Dated: October 25, 2018) ABSTRACT Radiations produced by neutrino-antineutrino annihilation at the Z0 pole can be used to heat up the primary stage of a thermonuclear warhead and can in principle detonate the device remotely. Neutrino-antineutrino annihilation can also be used as a tactical assault weapon to target hideouts that are unreachable by…

Aspects of the Color Flavor Locking phase of QCD in the Nambu-Jona Lasinio approximation co-written by R. Casalbuoni1, R. Gatto, G. Nardulli,and M. Ruggieri, TH-Division, CERN, CH-1211 Geneva 23, Switzerland Depart. de Physique Th ́eorique, Universit ́e de Gen`eve, CH-1211 Gen`eve 4, Suisse cDipartimento di Fisica, Universit`a di Bari, I-70124 Bari, Italia dI.N.F.N., Sezione di Bari, I-70124 Bari, Italia Abstract We study two aspects of the CFL phase of QCD in the NJL approximation. The first one is the issue of the dependence on μ of the ultraviolet cutoff in the gap equation, which is solved allowing a running coupling constant. The second one is the dependence of the gap on the strange quark mass; using the high density effective theory we perform an expansion in the parameter (ms/μ)2 after checking that its numerical validity is very good already at first order.

Introduction The existence of color superconductivity at very large densities and low temperature is an established consequence of QCD (for general reviews see [1], and [2]). Since at lower densities one cannot employ perturbative QCD, a popular approach in this regime is the use of a Nambu-Jona Lasinio (NJL) model. The mathematical procedure consists in solving the mean field gap equation and…

The Death of the Ball Turret Gunner

The Death of the Ball Turret Gunner is a five-line poem by Randall Jarrell published in 1945. The poem is about the death of a gunner in a Sperry Ball turret on a World War II American bomber aircraft. From my mother’s sleep I fell into the State, And I hunched in its belly till my wet fur froze. Six miles from earth, loosed from its dream of life, I woke to black flak and the nightmare…

A Unified Theory of the Mandela Effect written by Haoxuan Huang Independent Researcher

MANDELA EFFECT Abstract The Mandela Effect—the phenomenon whereby large groups share identical “false” memories that contradict official records—has been conventionally attributed to collective memory errors or dismissed as internet folklore. However, existing explanations fail to account for critical empirical patterns: (1) the systematic restriction of discrepancies to historically…

Haiku: The Heart of Japan in Seventeen Syllables

A haiku is the world’s shortest poem consisting of seventeen syllables. Despite its succinct form, it contains the essence of Japanese people’s aesthetics, view of nature, philosophy, thought, and sentiments. A haiku must have a kigo (a word connoting a season) and are rendered in three lines of 5, 7, and 5 syllables each. The kigo is a reflection of the Japanese people’s sensitivity to the…

THE SPEED OF GRAVITY

5.2 Dimension–8 Curvature Operators Following from the previous logic, we may also inspect the effect of dimension–8 curvature operators (fourth power of curvature) on the graviton speed of sound. Such operators are known to arise in the effective action for string theory from tree level α′ corrections [85, 86]. These were considered in [11] for Ricci flat backgrounds with the following effective…

THE SPEED OF GRAVITY

4 Superluminality & Causal UV Completions On NEC preserving backgrounds, we have seen that gravitational waves have superluminal low energy speeds if the coefficient CW2 of the Weyl–squared operator in the EFT of gravity is positive. If one were to jump to conclusions at this stage, one may be inclined in arguing that consistency of the EFT requires setting CW2 to be negative (this is indeed the…

Introduction In this new era of gravitational wave astronomy, it is especially important to understand how gravita- tional waves propagate. The recent simultaneous observation of gravitational waves from the coales- cence of two neutron stars, GW170817, together with its gamma–ray counterpart, GRB 170817A, has put the cleanest constraint on the propagation speed of gravitational waves relative to…
