Aethro-dynamics Review

Aethro-dynamics
Average Reviews:

(More customer reviews)

When I got the package in the (snail) mail today, my first impression was "this is a THIN book". So much for expectations. Steven's first book, Aethro-kinematics, was (is) the same size pages, but it is one and a quarter inches thick, and 523 pages.
Aethro-Dynamics is just shy of 1/2 inches thick, and 153 pages.
The first real section (the 1st section is a one page insert of the CD containing the book, Aethro-kinematics) is magnetism (Ferromagnetism as if there is a difference).
Steven provides us with more historical prospective of the inquiry into the mystery of magnetism, just like he did in his first book. This one has more references to "other people's opinions", which is of little help, since these "giants" never did figure out how magnets work. Steven provides us with the same theory from book one, that magnetism is a "flow" of aether. Nothing new here.
And he skipped over any reasoning for why the magnet "flow" only affects iron sized molecules. Steven and I talked (1995) about the need for some special attribute of this flow to distinguish between Aluminum, Iron, Gold, and Wood.
The forth section is labeled "Revisiting gravity, free fall and inertia". The historical review is good or better than the first book, BUT after repeating his Aether sink-vortex theory (from book 1), Steven still can not bring himself to say that Gravity equals the vertical flow of the Aether. The best he could do was
to hedge his language with "Aethro-kinematics, thus postulated a centripetal, spiral gravitational inflow of Aether into all accreting Matter." Page 135.
I was not nearly as impressed with this book as I was with the first book, 15 years ago.

The theory of an all-pervading physical Aether as forming a 'cosmosphere' by its randomly moving constituents, the 'Aethrons', producing an isotropic static pressure on every point of the Universe. The 'natural vorticity' (Descartes) of this medium creates local rotations in the fluid which are condensed by the pressure and evolve into dynamic matter. The first permanent and encapsulated evolutionary unit is a 'donut-vortex-dipole' equal to the modern 'electron dipole', that continues to evolve in all magnitudes of atoms, molecules, solar-systems, galaxies, etc. The model of the Aether is based on the simplest form of Newton's mechanics, but declines his 'Universal Gravitational force' by replacing it with a new force due to the 'Evolution of Matter' thru the dynamic condensation of the Aether into subatomic, atomic and molecular systems, encapsulated into units by the cosmic pressure. Thus, 'matter' is the condensation of rotational dynamics of Aether. All evolving matter consumes the cosmosphere and this procedure rarefying the Aether, that is, create a 'suction force' produced by the inhalation of Aether by the cosmic bodies, feeding their internal evolution. Consider the following enigmas of present physics: Galileo's 'Inertia' and 'Principle of Equivalence' , Newton's mysterious identity of 'gravitational and inertial masses' for explaining Galileo and saving his own derivation of the Kepler's formula. Coulomb's negative and positive fluid charges creating the neutrality of matter, instead of Franklin's much simpler an sensible 'one fluid' theory with its 'surplus', or 'deficiency' on the electrified objects. Faraday's mysteriously visible magnetic and electric lines of forces in empty space and Maxwell's inability to build a model of Aether which forces him to a Langrangean mathematical detour and to postulate an enigmatic 'displacement current' without a conveying Aether. J.J. Thomson discovery of the first subatomic particle, named as 'electron' and defined as a negativeÂcharge carrier in one of Coulomb's two fluids. Rutherford discovered a second subatomic particle, the 'proton' being 1836 times more massive than the electron, but inherits the 'same unit charge' as the electron, but 'positive'. Thus the proton became the nucleus of the Hydrogen atom, with one orbital electron. Einstein demolished all Aether theories, postulated that the speed of light is the limit of the motion of matter and discovered that the 'inertial mass' of an object is increasing when it is approaching the speed of light. His gravitation is not a 'force', but simply an 'acceleration field', that is due to 'the effect of mass on geometry, as it curvesÂEuclid's straight line motion into orbits according to the inverse square law of action at a distance. 20th century physics finally concludes that protons are imprisoned in the nucleus and could not 'flow' at all, thus the 'electric current' is not the positive fluid of protons as Coulomb suggested, but the negative 'Electron Current'. Nevertheless, the protons are still repelling each other with an immense force of repulsion in the tiny nucleus, therefore, to save the 'electrostatic model of the atom' and Coulomb's whole theory had to be mathematically saved by the newest 'Standard Model' of 'Quantum Mechanics' by postulating an immensely 'Strong Nuclear Force', which is just enough strong to cancel the protonic repulsion in the nucleus but short-range enough to leave a good old attraction field alive to keep the electrons on their orbits at 10.000 nuclei-diameters distance away in empty space...by 'action at a distance'. All these are described, explained and resolved here by Aethro-dynamics that is also contains a full CD version of the first volume; Aethro-kinematics for detailed history.

Kudos to author Carmella Van Vleet and her publisher Nomad Press for their dedication to publications about the environment aimed at being informative, educational and fun for middle grade and young adult readers. Amazing Arctic & Antarctic Projects You Can Build Yourself encourages independent reading and exploration. The book is full of interactive activities and fascinating factual tidbits. Words to Know, Did You Know and Fun Things to Try are featured on every page so that the reader never faces boring blocks of tiresome text. More detailed projects are contained on Make Your Own pages. These include several projects that with a little creativity could serve as the basis of a prize winning science fair or social studies fair project. For example, the Make Your Own Toboggan with Wheels could be combined with using different mixes of ice for an experiment on how pollutants affect vehicle movement. Similar additions could be made to Make Your Own Neutrally Buoyant Cup. I bought this book for my 6th and seventh graders but it is an important source of information for students, parents and teachers.

Complex Analysis Review

Complex Analysis
Average Reviews:

(More customer reviews)
Gamelin's book covers an interesting and wide range of topics in a somewhat unorthodox manner. Examples: Riemann surfaces are introduced in the first chapter, whereas winding numbers don't make an appearance until halfway into the book. Cauchy's theorem and its kin are instead developed in the context of piecewise-smooth boundaries of domains (in particular, simple closed curves) and only later generalized to arbitrary closed paths, almost as an afterthought.
In general, the author successfully conveys the spirit of the subject, and manages to do so quite efficiently. It's not the most painstakingly rigorous text out there, and the reader is expected to fill in some of the details himself, but the payoff is that a lot of ground is covered without getting bogged down in technicalities. In many books on this subject it can be tough to see the forest for the trees. This one is a pleasant exception.
There are a lot of good complex analysis books out there: Conway, Ahlfors, Remmert, Palka, Narasimhan, the second half of big Rudin, and of course Needham's "Visual Complex Analysis." (And many others that are well-regarded but that I have not looked at, such as Lang and Jones/Singerman, as well as the old classics by Hille, Knopp, Cartan, Saks and Zygmund.) Every one of these has its own perspective, and complex analysis is a big, multifaceted subject that is perhaps best studied from multiple points of view. Anyone wanting to learn this subject well will benefit from having several books at hand.
Gamelin's contribution to the pantheon is not revolutionary, but it does collect between its pages a wide assortment of topics not generally found in a single text. The reader is whisked from the basics to the Riemann mapping theorem in 300 pages with surprising ease. The ensuing "topics" chapters include a dynamical systems-flavored section on Julia sets and fractals; special functions (gamma, zeta, etc.); the prime number theorem; and an introduction to abstract Riemann surfaces.
Overall a fun text. Certainly not the only complex analysis book one should read, but then again the the same can be said of any complex analysis book. My only real complaint is that the selection of exercises is somewhat small in some chapters.

The book provides an introduction to complex analysis for students with some familiarity with complex numbers from high school. The first part comprises the basic core of a course in complex analysis for junior and senior undergraduates. The second part includes various more specialized topics as the argument principle the Poisson integral, and the Riemann mapping theorem. The third part consists of a selection of topics designed to complete the coverage of all background necessary for passing Ph.D. qualifying exams in complex analysis.
