Planetary Magnetism

Authors: Nainan K. Varghese
Comments: 9 Pages. Originally published in General Science Journal

It is generally believed that planetary magnetism is the result of motion of molten iron alloys in planetary body’s core region. An assumed dynamo mechanism, in core region of a planetary body, generates magnetic field by feedback loop: electric current loops in the region creates magnetic field and changing magnetic loops in turn creates electric fields. This assumption uses circular logic. As linear speed of a spinning planetary body is much greater than (tangential) linear motion of its constituent matter particles due to planetary body’s spin speed, every matter particle in spinning planetary body always moves in same direction in space. Spin motion of a planetary body is an illusion and it is valid only for considerations with respect to static reference of planetary body’s spin axis. As real motion of all matter particles of a spinning planetary body (with respect to absolute reference) is always in same linear direction, swirling motion of a planetary body’s interior is a myth. To consider this imaginary swirling motion of planetary body’s magma, as the cause of planetary magnetism is not tenable. Even for dynamo effect to occur, a primary source of magnetism is required, which is absent in this case. Cause and nature of planetary magnetism, described in this article, is based on a radically different concept, presented in ‘MATTER (Re-examined)’. For details, kindly refer to same [1].

The Nature's Selection of Cubic Roots

Authors: Jin He
Comments: 10 Pages.

The English naturalist Charles Darwin established that all species of life have descended over time from common ancestry, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection. In fact, Darwin theory dealt with the evolutional phenomena of the biosphere, not its origins. Further more, there exist the natural worlds other than our beloved one. Compared to the large-scale structure of galaxies, the biosphere is "microscopic". The electromagnetic and nuclear forces which rule the world disappear in the formation of large-scale galaxy structure. Similarly they disappear in the formation of the solar system. My previous papers showed that large-scale galaxy structure originates rationally from an algebraic cubic equation. This paper presents the nature's selection of the cubic roots and its application to the galaxy NGC 3275.

Astrophysics at Home. Micrometeorites.

Authors: Giuliano Bettini
Comments: 11 pages.

As stated in P. Rochette et al., "Micrometeorites from the transantarctic mountains", micrometeorites constitute the main part of the flux of extraterrestrial matter accreting on Earth. They are very important to understanding the composition of the solar system. Micrometeorites have been recovered from a variety of terrestrial surfaces (desert, beach sands etc.), showing that their deposition can be evidenced on any surface, provided that the accumulation time is sufficient, and discrimination from terrestrial particles is feasible. I present here my amateur activity of micrometeorite collector in the backyard and in desert sand. Sahara desert sand brought to me by my friend Silvia Calamity.
