What am I doing?

Today we had an academic meeting. The issue was: What to teach Mathematics Education students for their bachelor's degree?

I found this online:


"Why Major in Mathematics Education?


Employment
prospects are excellent for mathematics education degree students. A
critical shortage of math teachers exists throughout the nation,
creating increasing demand for bright new instructors. Graduates of the
mathematics education degree program also have the basic background to
pursue careers in the mathematics industry.


The mathematics
education degree program joins faculty from two top-notch programs.
College of Arts and Sciences mathematics faculty provide mathematics
instruction while College of Education faculty teaches education
classes. Mathematics education degree students also receive appropriate
field experiences teaching in selected west Michigan high schools.


The
Ferris State University mathematics education degree program requires
classes in general education, mathematics major and professional
education. A teaching minor is also required. You cannot have a
mathematics teaching minor with this teaching major. Mathematics
education degree students complete one semester of directed teaching at
the high school level. Upon completion of the Mathematics education
degree program requirements, Mathematics education degree students may
apply for Michigan Secondary Provisional Certification. Candidates are
required to pass state-mandated Subject Matter Exams in selected
teaching major and minors prior to certification recommendation."

Here in Guerrero, it is only one academic group which is in charge of both, the education, and the mathematics parts.

Why is this so?

History.

I won't try to explain it here; suffice it to say, that what we are doing is not the only way to do things.

I have to learn more education material.

Gabino Barreda

I just finished reading "El positivismo y la circunstancia mexicana" by Leopoldo Zea. He analyzes Gabino Barreda's contribution to Mexican Public Education during Benito Juarez's government.

He changed the curriculum at the "Escuela Nacional Preparatoria" (National High School, Mexico City), from scholastic to positivist. This French Philosophy,Positivism, was created by August Comte. In Mexico Barreda saw a way to make it Mexican. Eventually it was the ideological basis for the emergent Mexican Bourgeoisie.

Porfirio Díaz and a group of "Científicos" led Mexico during a few years of Order and Progress, until the Mexican Revolution changed that old regime.

Gabino Barreda is the ideological father of that Mexican historic period; and Leopoldo Zea became the "authority" and Mexican Positivism.

The Huitzuco Mercury Mine that I mentioned below, was the property of Porfirio Diaz's wife, Carmelita Romero Rubio de Díaz. These "Scientists" so enraged the people of Huitzuco, that on February 28, 1911, they fought against the Diaz Army in Huitzuco, and as they say, the rest is History.

Cubic Number Fields and Jacobi's Problem

"C. G. J. Jacobi (1804-1851) was the first mathematician who studied multidimensional continued fractions. His main objective was to find a generalisation of Lagrange's famous theorem which characterises quadratic irrational numbers as periodic continued fractions. He proposed an algorithm for number pairs in the hope that this algorithm will become eventually periodic if and only if both numbers belong to a cubic number field. Jacobi found some examples, but he could not show that Lagrange's theorem is true for this algorithm. In fact, the problem is still open!"
That is Professor Fritz Schweiger quote.

Hermite-Jacobi Problem

"In 1848, Hermite asked Jacobi for methods of expressing a real number as a sequence of integers such that the algebraic properties of the real number are reflected in the periodicity of its sequence. In other words, Hermite wanted a generalization to cubic and higher degree algebraic numbers of the fact that the decimal expansion of a real number is periodic if and only if the real is rational and, more importantly, of the fact that the continued fraction expansion of a real number is periodic if and only if the real is a quadratic irrational. Such attempts are called multidimensional continued fractions."

This quote is from:

Assaf et al.

Mercury from Huitzuco, Mexico

"On Some Remarkable Mercury Ores from Mexico.
By F. SANDBERGER (Jahrb. f. Mineralogie, 1875, 874-876).
THE specimens examined by the author came from Huitzuco in the province of Guerrero. It was observed that there was a complete series of changes, viz., from fresh antimonite to pseudomorphs of cinnabar after antimonite, in which only a trace of antimony could be detected. The large-foliated radiating and columnar antimonite is attached to a very hard gangue of brownish massive quartz, and only exhibits now and then a formation of stiblite on the edges, but neither of these minerals contains a trace of mercury. When the decomposition has taken a firmer hold, the antimonite crystals appear to be almost completely changed into stiblite, and at the same time impregnated either partially or completely with dull, black, amorphous sulphide of mercury (metacinnabarite of G. E. Moore). In fact, this mineral sometimes has the appearance of a pseudomorph of metacinnabarite after antimonite, but its sp. gr. is only 5.39 at 18o C., the hardness is 5.5, and the blowpipe reveals the predominating presence of stiblite, so that it is a mixture of a small amount of the sulphide of mercury with a large amount of stiblite. On igniting a small splinter of the dull black mineral before the blowpipe, its volume scarcely alters, but the colour changes to white and it remains infusible. On charcoal it gives only a weak sulphur reaction; but a little mercury is detected on heating a portion in a closed tube with sodium carbonate. A further stage is the passage of these black columnar masses into cinnabar, the change taking place in the spaces between the laminæ and gradually penetrating deeper. Some specimens consist of from 1/3 to probably 9/10 cinnabar ; in the first case they are still hard, and mostly black or only streaked with red, whereas in the last they have an intense cochinealred colour, and are earthy and brittle. The characteristic cleavages of antimonite (parallel to ∞P and sometimes P) are still discernible on the most perfect crystals, and antimony can always be detected in the specimens, although it is sometimes present in minute traces only. It is certainly extraordinary that the original crystal form should be retained so tenaciously throughout the three changes which it undergoes before eventually becoming cinnabar, viz. : (1.) Oxidation to stiblite ; (2.) Impregnation by metacinnabarite and complete displacement; (3.) Alteration of the cinnabar into metacinnabarite. The author endeavours to account for these remarkable changes from the fact that gypsum is always in clefts and between the laminæ of the antimonite which is passing through the three stages given above. It seems therefore that there is a close connection between its presence and that of sulphide of mercury ; further it can be assumed that this gypsum was originally calcium sulphide, and this latter substance may have dissolved some of the sulphide of mercury and introduced it into the antimonite mass, the result being the formation of pseudomorphs.
Calcium sulphide easily decomposes in air, becoming eventually gypsum, but sulphide of mercury does not change.
Fleck and v. Wagner have proved that barium sulphide dissolves sulphide of mercury ; the author therefore supposes it to be probable that calcium sulphide will behave in a similar manner.
C. A. B."
The abstract above was taken form:
Chemist Sandberger describes the special properties of Mercury from Huitzuco in this abstract. This text is from 1875.

Huitzuco 1942

Today I am telling you a story:
Sixty six years ago there was a beauty contest. Emma Uriza Castro (right) v.s. Beatriz Arizmendi Celis, (left) were the Beauty Queen candidates.
One was supported by the Huitzuco Mine (above) manager, and the other was not. Sources tell me that money was given to miners to vote for one of them. She won; the young people behind the losing candidate, that then became Princess, not Queen, were so outraged, that they decided to organize an alternative celebration. The Princess became a Queen, with a silver crown and all. In a really big hall, next door to the Real Queen's house, they had a Royal Celebration.


At the end good won over evil. Of course the Queen was my mother, (Emma Uriza Castro) and we kids broke that beautiful crown, without knowing all the passions that it arose.

Beaver and Garrity

These authors have made some inroads in Jacobi's problem.

A Two-Dimensional Minkowski ?(x) Function

They write:

"The goal of this section is to show that δ(x, y) maps a class of pairs of cubic irrationals to pairs of rationals. Unfortunately, we cannot make the claim that δ maps all pairs of cubics (even in the same number field) to pairs of rationals."

To this day, one cannot go both ways. Not all pairs of cubics go to pairs of rationals. Only a class of pairs of cubic irrationals goes to pairs of rationals.

These authors end their paper thus:

"Finally, the initial Hermite problem remains open."

Cubic Roots of Irrationals

Carl Gustav Jacob Jacobi tried to do for cubic roots of natural numbers, what Lagrange had done for square roots of natural numbers; classify the regularities found in the case the cubic roots were irrational numbers.

He did not find regularities. To this day mathematicians are looking for any regularities in one cubic root, or sets of cubic roots of natural numbers.

This generalization from power two to power three, reminds one of other apparently simple generalizations that did not happen. Perhaps the most famous one concerns Diophantine Equations of natural numbers. For power two, we have an infinite set of triplets satisfying Pythagoras Theorem:

[2k(k+1) + 1]2 = [2k(k+1)]2 + [2k + 1]2

for any natural number k.

When Fermat looked into the generalization to power three, he claimed to have proved it was impossible for this case.

It was only many years later, in the early nineties of last century, that Andrew Wiles finally proved that statement to be true.

In Physics we have the exact solution for the two dimensional Ising Model, found in the middle of last century by Lars Onsager. To this day physicists are hard at work; with nothing to show.

"Jacobi's Last Theorem", as Professor Fritz Schweiger calls it, is patiently waiting for a modern day Wiles to conquer it.

Thoughts

My situation is interesting. I have reconnected with part of my family, now I know little Jalil Azar Cárdenas. He is not even five, I don´t think. He is going to kindergarten in Huitzuco, where my mother went to grammar school.

I feel well after visiting my relatives in Guerrero state. On the other hand my direct family, wife and kids, are in Warrenvile, you can read below that recently a storm caused havoc in the neighborhood.

I can help here, but I do not know if I'll make enough money to keep my family in the US.

Who is running Mexico?

You can read about the wild west style shoot out in Zirándaro, Guerrero, México, below. Also about a 14 year old girl killed in Acapulco. This is not right. Calderón's government is responsible. National Action Party has been governing several states ridden in violence, and they have not been able to bring more sanity to México.

In México City, run by the opposition, Democratic Revolution Party, also criminals recently kidnapped and killed a young man by the name of Martí.

I have written here before, that I believe part of the problem comes from the new rich, that is, young Mexican Indians, that have gone to the US, and come back with money, but no respect. If all Mexicans are not respected and taken care of, I can only expect more and more violence.

UNISUR is a ray of hope. Universities for Mexican Indians, enough is enough.

As you can read in this space, I recently went to Xalitla, for the land grant ceremony by an indian town, that wants a University. I repeat here, the Mexican Government of Felipe Calderòn is NOT helping. As long as this continues this way, I expect more Pascuales, like Pascual Monje Solís.

Pascual Monje Solìs

"El general retirado del Ejército agregó desde muy temprano, en los círculos policiacos corrió la versión de que Monje Solís logró romper el cerco porque se disfrazó de soldado y pudo burlar al Ejército y a los policías federales, estatales y municipales, porque físicamente nadie lo conoce."

My translation is:

"The retierd Army General added early on, among policemen there was the rumor that Monje Solìs was able to escape because, dressed as a soldier was able to deceive the Army and the federal, state,and county police, because nobody knows his face."

This report was taken from Marlen Castro of the newspaper: "La Jornada Guerrero".

This incident happened in "Las Mesas", Ziràndaro County, Guerrero.

The escapee had been trained in the US when he was in the Mexican Army, and now he serves other powerful Mexicans, not the rest of us that pay taxes to keep the Army.

I feel I am going back, not only home, but to the wild era of our country. One wonders if there is progress.

They fed us and several children from the Upper Balsas Region in Guerrero State performed. Initially they will start up classes at the Carlos Darwin Junior High School building in Town next month.

The State of Guerrero is not financing the effort, but it seems to me that if the people of Xalitla really want a University Campus, they'll have one.

I wouldn't be surprised if they ask me to teach there, first though, somebody from around here has to pay me.

Chew's Meaning of Mass

Geoffrey F. Chew has proposed an alternative to the "Standard" view that Theory must give all scales in Physics. One can read:

"Intervals within our c-based Feynman paths are straight and positive lightlike. These paths propagate wave functions that, in representing massive particles, exhibit ‘zitterbewegung’ (zbw) --fluctuating positive-lightlike 4-velocities-- in a sense recalling that displayed by Dirac’s single-electron wave function which lacked a relativistically-invariant norm. Our massive particles, both bosons and fermions, emulate in certain aspects Dirac’s electron, although the latter's wave-function norm was boost dependent and its mass was regarded as a given scale-setting parameter. We here depict electron mass, through a ‘physical’ infinite-dimensional unitary Poincaré-group representation, as a ground-state energy whose value is dynamically determined, along with that of all particle masses, by wave-function stationarity over macroscopic intervals of ‘universe time’. We recognize an extended meaning for ‘zitterbewegung’—as parity-dictated fluctuation of any massive particle’s ‘substructure’, in both velocity and momentum."

Mass then is "dynamically determined". I understand from that phrase, that Chew views "fundamental physics", with a humble position. S Matrix Theory, expressed observations with the tools given to us by the mathematics of space time, here Gelfand-Naimark, provide the finite answers that were not possible before. Besides that, we have two different scales, cosmological and quantum, Chew just lives with both, and leaves for a future, maybe "Number Theory" based, physical theory, the task of getting those numbers. Some kind of stability condition, may in some future time tell us: Why the electron has the mass it has?

Resumen


Parece ser que la idea clásica de Selección Natural, ya se puede generalizar.—Darwin no conoció la no-localidad inherente en la Mecánica Cuántica. — el azar no tiene suficientes elementos formativos. Es difícil entender como el mismo principio de Darwin, puede incorporarse a la idea de Gaia de Lovelock.Parece que la dificultad de los contemporáneos de Lovelock,es la falta de un principio de selección generalizado. Para aumentar la dificultad ahora se sabe que los sistemas solares del Universo están regidos por principios de organización que se usan para hacer los códigos numéricos que predicen una gran cantidad de planetas como nuestra Tierra, que están siendo descubiertos por los astrónomos. Más aún, parece haber un patrón de formación de galaxias conectadas en una Gran Red Universal que parecen un organismo Cósmico.





Introducción

La similaridad de las estructuras en escalas que van de lo cósmico a lo local puede ser debido a más elementos, que la clásica invariancia de escala de la gravedad. Lo que se propone aquí es otro elemento de esta similaridad, a saber: la no-localidad cuántica. A este principio se le llama, Selección Natural Coherente (SNC).

El siglo pasado Aspect et al., observaron la primera evidencia de no-localidad. Ahora ya son varias las observaciones de este importante aspecto del mundo. Generalmente se tratan las cuestiones de la Biología como clásicas, no cuánticas. Pero es evidente desde ya hace muchos años el efecto en la mutación genética de la radiación que afecta a las regiones más locales de que somos conscientes; las vecindades de los electrones y protones de que está hecho el Ácido Desoxirribonucleico (ADN). Aquí se propone entender el carácter coherente de la materia, i.e., su aspecto no-local, como formativo; es decir, azar más coherencia es igual a forma.

Recientemente Hartle, Hawking, y Hertog (HHH), propusieron una regla para obtener el Universo que tenemos con la condición inicial, de que no hay frontera, y estudiaron el caso de un mundo semiclásico en el presente. Estos autores encuentran una probabilidad notable de que el Universo pase por una contracción que no termine en singularidad.

Stephen Hawking demostró hace muchos años, junto con Roger Penrose (HP), que con unas suposiciones razonables los colapsos gravitacionales terminan en singularidades. Lo que HHH nos dicen ahora es que al incorporar principios de Mecánica Cuántica con hipótesis extras, se violan las condiciones usadas por HP. Sin la inevitable singularidad clásica, parece que ahora se puede se puede usar el principio de SNC.

Recientemente el matemático ruso, Grigory Perelman, demostró que cualquier variedad diferenciable completa, es una esfera en tres dimensiones. Otra forma de decirlo es: cualquier variedad compacta y simplemente conexa es una esfera en tres dimensiones. En esta demostración Perelman usó una variable auxiliar que parametriza las posibles métricas. Al derivar el tensor métrico con esta variable obtiene una ecuación localmente parabólica que le permite demostrar que en un número finito de pasos puede modificarse adecuadamente la variedad para eliminar todas las singularidades.

Este parámetro juega el papel del tiempo en este formalismo. Un tiempo dirigido, que marca puntos de partida y direcciones de cambio. La demostración consiste, entre otras cosas, en demostrar que el radio de curvatura de Ricci está acotado. Para Perelman este parámetro es una herramienta útil para su demostración; pero uno lo puede considerar el verdadero tiempo, que junto con las tres dimensiones de espacio, forman el espacio-tiempo de la física.

Una posible conceptualización de esta construcción es la de Julián Barbour. Para este físico inglés el tiempo no es físico, sini mas bien una manera en que los seres humanos organizamos patrones en tres dimensiones. Así como en una película, el tiempo transcurre para nosotros cuando la siguiente imagen es casi igual a la anterior. Así en el mundo físico, todas las fotos ya están, nosotros sólo las ponemos en orden. La Información, ésto es, la expectativa de lo que sigue, es lo que permite la percepción del tiempo en nuestra mente. Desde esta perspectiva, Perelman y Barbour, nos dan herramientas para resolver un problema conceptual de la Gravedad Cuántica, al clarificar la categoría de la Información en la física. El Universo es un grupo de objetos relacionados entre sí, en cúmulos de tres dimensiones, con un orden de cercanía de patrones; la similaridad entre patrones está dada por la Información, o mejor dicho, la similaridad entre patrones es la Información.

En esta cosmovisión, la cantidad de movimiento, o inercia, es covariante con las tres dimensiones del espacio, y la Información, es covariante con el tiempo. Perelman define cantidades auxiliares para su demostración, que recuerdan al concepto de entropía, la cuál desde el trabajo de Boltzmann, está asociada con expectación, o probabilidad; como Claude Shannon mostró algunos años después.

El concepto de covariancia es importante aquí. Percibimos el cambio en el espacio de tres dimensiones, y lo etiquetamos con el tiempo. Covariante se entiende, como la percepción de que el tiempo también cambia, al cambiar la imagen en tres dimensiones. En la geometría diferencial, este concepto está formalizado, pero esencialmente se entiende, como los cambios de una variable, asociados con los cambios en otra. El cambio pues, es esencial, en este esquema, no tanto el aproximarse a un límite, o tener una curva continua, sino percibir el cambio. Con Heráclito de Éfeso podemos decir que todo es cambio.

Cubic Irrationals

Hermite problem is:

"Peut-être parviendra-t-on à déduire de là, un système complet de caractères pour chaque espèce de ce genre de quantités, analogue par exemple à ceux que donne la théorie des fractions continues pour les racines des équations du second degré"

Another way to state this concern is:

"Find methods for expressing real numbers as sequences of positive integers so that the sequence is eventually periodic precisely when the initial number is a cubic irrational."

Another description of the problem is:

"In 1848, Hermite asked Jacobi for methods of expressing a real number as a sequence of integers such that the algebraic properties of the real number are reflected in the periodicity of its sequence. In other words, Hermite wanted a generalization to cubic and higher degree algebraic numbers of the fact that the decimal expansion of a real number is periodic if and only if the real is rational and, more importantly, of the fact that the continued fraction expansion of a real number is periodic if and only if the real is a quadratic irrational. Such attempts are called multidimensional continued fractions."

Jacobi tried unsuccessfully to solve this problem.

Periodicity in Cubic Number Field

Jacob Jacobi in 1868 published his studies in Number Theory. Professor Fritz Schweiger writes:

"Maybe he was warned off by the long calculations for (1; 5¹/³; 25¹/³) and the obviously never ending calculations on (1; 4¹/³; 16¹/³). In fact, it is still not known if periodicity occurs at all!"

I am curious to understand the problems Jacobi run into.

Reason

Prædiciere

The current crisis is a test to our intelligence. Other mammals do not spend their time finding a way out of the world crisis. I myself have problems. People around me go about their lives with a business as usual attitude. I feel unsettled.

The Latin word I have in this note means to predict, to say it before it happens. That is what reason is for.

My reason is hard at work to find a valid prediction, for me and for the world.


Discrete Quantum Cosmology

One can read from Chew:

"Although consistency requires slice width to be an integral multiple of arc step, the huge-integer ratio will not be addressed by the present paper—which ignores arc steps and number theory. Before attending to path arcs this paper chooses to address the single-preon Hilbert-space path basis. Nevertheless the termination of path arcs at exceptional (ray-age) hyperboloids might be taken as defining the path basis of preon Fock space."

This is one place where number theory may enter into play for Chew's Theory.

Geoffrey F. Chew

This UC Berkely Professor believes that:

"number theory may eventually render non-arbitrary the integral ratio of spacetime-slice width to path step. Particle scale would thereby, like path step, become set by the trio of universal parameters G, h and c, whose values Planck realized do not require ‘explanation’."

I do not yet understand what Professor Chew is saying. I know that he has looked into the conundrums of particle physics longer than I have. Nevertheless I also believe that number theory has something to tell us about why the world is as it is.

For me the main problem of Physics today is to explain stability. Why in a Hydrogen atom is an electron always moving around a proton and never going inside the proton? To say that that is forbidden by Quantum Mechanics, is philosophically a poor practice. What is first stability, or Quantum Mechanics?

Curvature

Long ago I thought that curvature was a deep concept we owe to Carl Friedrich Gauss. Then I saw that phase-space was deep also. It seems that now more people are coming to the same conclusion. Here I try a simple interpretation in my understanding of Julian Barbour's ideas.

Pattern is time. We know what comes next because of our expectations. The arrow of time is as real as the persistence of objects. Linear predictions are called common sense, but Ray Kurzweil has shown us to extrapolate with non-linear functions. Gauss then is the master of prediction. If we know the curvature in a local region, we know if linear or non-linear predictions are needed. Einstein also saw in curvature the key to a theory of physics.

Thermodynamics, General Relativity, and now Perelman's Theory of Ricci Flows, must be related. The relation may be Barbour's idea that there is no time, only patterns.

More to come.

Poincaré's Conjecture 1

"This conjecture states that the only compact three dimensional simply connected manifold is a three dimensional sphere."

Also we can say:

"that every compact and simply connected 3-manifold is a 3-sphere".

I am back. I was away from a nice place where to think and write. I found this statement in:

Christina Sormani's, piece on this intriguing piece of Mathematics.

I hope I can understand the General Relativity and Thermodynamics implications of Perelman's work.
