Kurt Godel: The World's Most Incredible Mind (Part 1 of 3)

Kurt Godel: The World's Most Incredible Mind.

Either mathematics is too big for the human mind or the human mind is more than a machine ~ Godel

Kurt Godel (1931) proved two important things about any axiomatic system rich enough to include all of number theory.

1) You'll never be able to prove every true result..... you'll never be able to prove every result that is true in your system.

2) Godel also proved that one of the results that you can never prove is the result that says that the system is consistent. More precisely: You cannot prove the consistency of any mathematical system rich enough to include the known theory of numbers.

Hence, any consistent mathematical system that is rich enough to include number theory is inherently incomplete.

Second, one of the propositions whose truth or falsity cannot be proved within the system is precisely the proposition that states that the system is consistent.

What Godel's proof means, then, is that we can't prove that arithmetic—let alone any more-complicated system—is consistent.

For 2000 years, mathematics has been the model—the subject—that convinces us that certainty is possible. Yet Now there's no certainty anywhere—not even in mathematics.

Goedel's Ontological Proof.

For those interested in a discussion of Goedel's reasoning for God, then I suggest starting with this heavily annotated work, which I recently stumbled upon.



It's not that God is subject to the Freedom Proof or the Doubt Proof.
According to Gödel, He's not. But we have to be, or else we are not free. So
our truth game with God turns into something like Feynman had described.
Feynman's Gods, every time physicists think they have the rules of the game
figured out, throw in a new wrinkle. They let people like Feynman make
progress, but if the Feynmans of the world learn too much, physics will stop
being the joy and challenge that it is. The Gods don't let that happen.

Gödel's God has to be very careful about how he lets our universe unfold.
If the world becomes totally controllable and comprehensible, we'll be God.
God does not object to that. In fact, according to Gödel, that is our destiny.
But it is also the end of us as free human beings. And human freedom is an
essential part of the beauty of God's universe.

Kurt Gödel's Philosophical Viewpoint

In his book, “A Logical Journey: from Gödel to Philosophy,” Hao Wang describes how he found a list of 14 philosophical points written by Gödel around the year 1960. Gödel had titled the list, “My Philosophical Viewpoint.” To understand Gödel's strange and magnificent worldview, we will go through each of these 14 points and analyze their greater significance.

Gödel's Incompleteness Theorems - In Our Time

In 1900, in Paris, the International Congress of Mathematicians gathered in a mood of hope and fear. The edifice of maths was grand and ornate but its foundations had been shaken. They were deemed to be inconsistent and possibly paradoxical. At the conference, a young man called David Hilbert set out a plan to rebuild the foundations of maths – to make them consistent, all encompassing and without any hint of a paradox. Hilbert was one of the greatest mathematicians that ever lived, but his plan failed spectacularly because of Kurt Gödel. Gödel proved that there were some problems in maths that were impossible to solve, that the bright clear plain of mathematics was in fact a labyrinth filled with potential paradox. In doing so, Gödel changed the way we understand what mathematics is, and the implications of his work in physics and philosophy take us to the very edge of what we can know. Melvyn Bragg discusses Gödel’s Incompleteness Theorems with Marcus du Sautoy, Professor of Mathematics at Wadham College, University of Oxford; John Barrow, Professor of Mathematical Sciences at the University of Cambridge and Gresham Professor of Geometry and Philip Welch, Professor of Mathematical Logic at the University of Bristol.

El Teorema de Gödel por fin Explicado Fácilmente

Gödel´s theorem easy. El teorema de Gödel explicado de forma fácil.

Esta historia, es una metáfora del Teorema de Gödel.
Comparte el nucleo de ideas de este teorema.

1. Las cajas representan las proposiciones de lógica de primer orden de la aritmética de Peano.

2. El escaner representa la función recursiva que permite saber si una secuencia de proposiciones constituyen la demostración de la proposición de la caja.

3. Godel permite que los objetos , los numerales, definidos por la proposiciones de la teoría, se refieran a otras proposiciones de esa teoria (con la famosa numeración de Godel). Es lo que digo: Inventó un método para que las cajas hablasen de otras cajas.

4. Crea una sentencia con una variable libre y luego introduce en esa variable el numeral de esa misma sentencia. Así crea una sentencia indirectamente autoreferencial que afirma que no existe una secuencia de numerales que corresponda a una demostración de ella misma. Esto corresponde a la caja que dice: la caja del interior introduce una copia suya en su interior, y ya no pasa la barrera, el interior vacío de la caja es la analogía de una variable libre en una proposición.

No digo, al final, que demuestre la incompletud de la aritmética de Peano, pero que esta arítmetica no puede ser completa y consistente a la vez. Y esta conclusión ya es un duro golpe para el Programa de Hilbert.

La historia de las matemáticas - 4. Hacia el Infinito y más allá

“Son los grandes problemas por resolver los que mantienen con vida a las matemáticas”, declara el presentador al inicio de este capítulo, que comienza con Hilbert desde la Sorbona para dedicarse después a recorrer algunos de sus célebres 23 problemas. Primer problema, hipótesis del continuo (Georg Cantor, el infinito, distintos tipos de infinito: biyección entre racionales y naturales, imposible con los números reales), Conjetura de Poincaré (Intento infructuoso de entrevistar a Grigori Perelman), Segundo problema (Kurt Gödel y el teorema de incompletitud, Círculo de Viena), la batuta matemática se traslada a EE. UU. (Universidad de Princeton) por la ocupación nazi (Hermann Weyl, John Von Neumann), Octavo problema, Hipótesis de Riemann, “la joya de la Corona” (Paul Cohen), Décimo problema (Julia Robinson, Yuri Matiyasevich, teoría de Galois, André Weil) y finalmente enlaza a Weil con el grupo Bourbaki y en particular con Alexander Grothendieck. Si Du Sautoy empezó con una cita, acaba con otra de Hilbert en una emisión de radio en 1930, que suscribe completamente (y probablemente lo hacemos todos): “Debemos saber, y sabremos”.

The Rotating Godel Universe

A lecture by our friend, Dr. Moninder Singh Modgil, given to QGR staff on November 15, 2017.

The Logician Kurt Godel, known for his “Incompleteness Theorems”, was a friend of Albert Einstein's while they were both at the Institute of Advanced Studies at Princeton.

In 1949, on the occasion of Einstein’s 70th birthday, Godel, in a seminar, presented a model of a rotating universe--the model which bears his name. This was the first solution of Einstein’s field
equation in which it was demonstrated that time travel was possible. Obukhov has researched a metric which combines expansion with rotation. The rotation is high in the early stages of the universe, and slows down as the universe expands. Observational evidence for
rotation of the universe is discussed.

About Dr. Moninder:

Dr. Moninder Singh Modgil specializes in the “Godel Universe,” which is a rotating universe solution of Einstein’s field equations. He received his PhD in General Relativistic Physics from the Indian Institute of Technology, Kanpur, India. He did his B.Tech. (Hons.) at the Indian Institute of Technology in Kharagpur, India, in Aeronautical Engineering and has worked on the aerodynamic design of the Tejas fighter jet. He has also worked on a collaborative atmospheric project between the Indian Space Research Organization (ISRO) and the National Oceanic and Atmospheric Administration (NOAA) in Boulder, Colorado.

Godel's Lasting Legacy

Austrian logician Kurt Gödel’s incompleteness theorems showed us the limitations of mathematics within mathematics. While math is still useful for proving scientific theorems, Gödel transformed the perception of pure mathematics in a way that still makes modern mathematicians uncomfortable. Here, leading thinkers—a mathematician, a philosopher, and a physicist—wrestle, almost literally, with the implications of Gödel’s legacy.
