BALL LIGHTNING AS A NON-CONSTANT ALPHA SPHERICAL FORCE-FREE MAGNETIC FIELD PLASMOID

A force-free magnetic field configuration is a state of minimum energy under the constraint of magnetic helicity conservation.  It is shown here that force-free magnetic field configurations that can be used for ball lightening can have alpha in the force-free field equation a scalar function rather than a simple constant.  Such fields have been proposed to contain the plasma of ball lightning.

PLASMA CORE ROCKET ENGINES

The basic physics for plasma core rocket engines was already completed in 1985.  At the time successful containment of a fissioning uranium hexafluoride U(93%)F6 plasma was achieved for ~120 seconds using an argon vortex.  Unfortunately, hydrodynamic confinement of a fissioning fuel in a gas core nuclear rocket without uranium loss is probably unachievable.  This article proposes a plasma core that is magnetically contained and uses one of many possible stable force-free magnetic field configurations.

Alterations in Human EEG Activity Caused During Exposure to Low Frequency Electromagnetic Fields

It has been known for some time that AC electromagnetic fields of less than 50 Hz can alter the EEG traces of human subjects.  Here AC signals of 10 Hz or 20 Hz were applied to the temples of a human subject while recording the monitored EEG traces. It was found that there were significant variations in the traces in both amplitude and frequency during the test period.

AN EXPERIMENT ON THE ELECTRICAL PROPERTIES OF HUMAN SKIN FOR AC VOLTAGES OF VARYING FREQUENCY

The resistivity of human skin depends on the layer within which it is measured. The DC characteristics are fairly well known; here, an experiment that measures the transport of AC signals through the skin is described.

Null-Killing Surfaces of the Kerr and Kerr-Newman Solutions of the Einstein Field Equations

The null Killing surfaces for the Kerr and Kerr-Newman solutions to the Einstein field equations are discussed, derived and plotted. For some parameters of the mass m, the angular momentum per unit mass a, and the charge e, the plots show some unusual features, particularly of the Kerr-Newman metric.

Life on Earth-like Planets: Gaia and Her Sisters

From its ancient Greek roots to Lovelock’s groundbreaking 1979 book, the concept of Gaia has evolved to depict Earth as a single, intricate organism sustaining life through the interplay of its organic and inorganic elements. From the Hadean epoch, where life’s emergence radically transformed our planet, to the present, Earth stands as our sole model for understanding life’s potential on other Earth-like worlds. While the lifeforms that evolve on Earth-like planets would not necessarily be identical to those on Earth, they must satisfy the same constraints. These constraints are the central subject of this book.

THE WAR BETWEEN HAMAS AND ISRAEL: IRAN IS THE WINNER

Before the war that began when Hamas brutally attacked Israel on October 7, 2023, Bahrain,
Morocco, Sudan, and the United Arab Emirates were on the way of normalizing their
diplomaIc relations with Israel and Saudi Arabia seemed poised to do so. This has all been
derailed. Iran is the clear winner.
