Shut me up, the stones will speak

12 Apr

It is not illusionism, pure utopia (Thomas Morus’s Utopia is the desire for a world with fairness), it is about understanding and respecting the mystery, of being aware that we do not know everything. It was not Einstein, but Heisenberg who first announced the quantum theory, which inspired Dali in his Mystical Manifesto, which changed the idea of ​​science, space, and time.

The image of the real black hole is just the tip of the iceberg of a mysterious universe, which surprises us and shows us our limitation.

Much of the contemporary regression is the incomprehension of cosmology and cosmogony, which in a different way are present in all cultures and religions.

Scientism, determinism, and materialism wanted to abolish the subjective thinking of cosmogonies, but it survived, and the discovery of the black hole is the enlargement of scientific cosmogony.

Says the biblical Reading (Lk 19:40) “if they shut me up, the stones will speak,” in the passage that the religious themselves asked Jesus not to speak of his eschatology, his mission and his end in the hands of the powerful. The quantum computation is explained by Shohini Ghose in 10 minutes:

 

 

The first image of the Black Hole

11 Apr

But in reality it is much more than that, and the proof of the theory of relativity, the variation of space and time (considered absolute in modernity), with the supermacious black hole photo, in the Center of The M87 Galaxy was unveiled on Wednesday at six simultaneous press conferences in Brussels, Washington, Santiago, Shanghai, Taipei and Tokyo.
It is the result of a decade of effort, made in five countries by the members of the EHT’s Collaboration of the Horizon of Events (EHT), and the imaging was done by telescopes connected to satellites in various parts of the earth see figure) to compose the image. But a black hole does not emit light, what was the photographer then-what does the image show at all? its shadow that it causes in its bright neighborhood, these rays of light in the surroundings deviated and distorted by its intense gravitational field form the reddish tones.
At its frontier happens a horizon of events, marking the points where even the light gets sucked out of gravity, is 2.5 times smaller than the shadow projects it, and yet measures 40 billion km from one side to the other, being this called Monster.
A 29-year-old scientist was important in the team of 30 researchers who helped compose the image, she is Katherine Bouman, a postdoctoral student at the Harvard-Smithsonian Center for Astrophysics and developed the algorithm for imaging.
The explanation of black holes is in video follow:

 

Mathematics woman wins Abel award

21 Mar

Niels Henrik Abel was born on August 5, 1802 in Finnoy, Norway, and died on April 16, 1829 in Froland, when he went to visit the bride on a sleigh, and died days later in 1829, his main work Recherches sur les fonctions elliptiques was published in 1827 in the first volume of Crelle’s Diary, a mathematics-only diary.
The Abel Prize was established in Norway in 2002, and now for the first time a woman wins the award, the American Karen Keskulla Uhlenbeck, who according to the Norwegian Academy of Literature and Sciences held “pioneering achievements in differential equations in Gauge Theory and integrable systems; and for the fundamental impact of his work on analysis, geometry, and mathematical physics.”
The Gauge Theories, or Caliber´s Theories, formalize a class of physical theories based on the idea that the symmetry transformations, which can be either local or global. These ideas apply not only to field theories, but to so-called finite-dimensional systems, as are those modeled by ordinary differential equations.
It is an important model in the generalization of the General Relativity Theory and curious that arises at the same time from the proof of the non-objectivity of science (see the post), although there is no immediate relationship, the fact that local results are not objective is interesting for a mathematical theory shows that they are both important, how would the composition of the two results be?
The Nature magazine on March 19 dedicated a special note to Karen.

Physicists prove: reality is not objective

19 Mar

What was a hypothesis is a fact demonstrated by experience, which in itself is already contradictory since something contradictory may be true, yet the experience at Scotland’s Heriot-Watt University has shown that two people can see the same reality of different forms and both are right, the article is published.

From the appearance of the observer the great hypothesis of contemporary science that reality is independent of the observer has fallen, the suggestive name of the article is exactly this: “Experimental rejection of the observer’s independence in the quantum world”, its authors are: Massimiliano Proietti, Alexandre Pickston, Francesco Graffitti, Pedro Barrow, Dmytro Kundys, Cirilo Branciard, Martin Ringbauer, Alessandro Fedrizzi, and is published in the archivX of Cornell University.

The experiment involved two people who observe the same photon, the smallest unit of light that can act as a particle or wave under different conditions, this being the novelty, which both observing on the same condition observe distinct realities, then it can be said that there is a superposition of reality, that is, both are both true.

While one scientist analyzes the photon and determines its alignment, the other without knowing its measurement, checks whether there is a quantum superposition or not, while one experiences reality as a particle and the other as wave, and both are technically correct.

The so-called 6-photon experiment, which is the simplest for experiments, verifies the so-called Bell inequality (which Einstein used to try to contradict the quantum phenomenon), and this measure can be verified experimentally by 5 measures of deviation standard (statistics) associated with it, is a bit complicated, but the result is this for those who know the phenomenon.

 

 

Good trip! Passengers to space

04 Mar

Elon Musk after revolutionizing the Tesla car, here in Lisbon I got in and I’m trying to test drive, after the revolutionary solar battery (do not adopt because of the electric and diesel trusts), now the first space travel with passenger was made. 
The SpaceX spacecraft, the first of a private project whose $ 250 million cost is a quarter of NASA’s cost, and has already docked at the orbital station on a quiet trip, still no passengers.
The tourist who paid part of the project is Yusaku Maezawa, a businessman who sold some in the mail and today has a clothing sales site called Zozotown, his identity was a long time in secret, Tesla’s BRF (Big Falcon Rocket) ship is reusable and was propelled by the Falcon 9 rocket, and should return to Earth in a week.
Maezawa’s project called DearMoon involves artist he enjoys and it’s a futuristic poetry without fail to have a business side.
SpaceX plans to reach Mars in 2022.
The details of the 8 tickets bought by Maezawa and her artistic dream are:


 

 

Line art, 3D and tesseract

19 Feb

The fact that contemporary culture is based on a science, an art and also an ethical and aesthetic dimension based on geometry has built an ideal model of nature, man and society, which is purely ideal and unrealizable to man.
It seems a post-humanism, since contemporary humanism is that of the Kantian categorical imperative: “Act as if the maxim of your action should become, through your will, a universal law”, sometimes the ” through his will, “but the imperious fact remains there, to become a model for others, narcissism and pre-humanism.
All this came from the idealism and absolutism of mathematical geometric ideas, it is not abstractionism since this current in both art and mathematics itself has in fact become much more revolutionary than it seems, the Hausdorff dimension and the fractals, as well as the mathematical and physical hypotheses about entropy prove this importance.
Physics in discovering the fourth dimension refers human thought and adventure to an unthinkable space, the intergalactic voyages, begins to draw the history of the universe itself, how supernovae form, what are black holes and black matter, finally a threshold of a new time, born of quantum physics and the fourth dimension.
What this has to do with art, with technology, absolutely everything, since the human vision and sensation widen, while many get into dogmatic holes, some even redeclarate the flat earth, the dimension of the infinite, the cosmogonies and the fourth dimension emerge
All this seems theoretical, but it was Carl Sagan in his famous Cosmos series, now available online, which explained all this in a simple and accessible way to all, follows a piece of your video in which explains this: 

 

Navigate deeper waters

08 Feb

Is a well-known expression in the Portuguese language “navigating is necessary”, but here the connotation of navigating deep waters refers to knowledge and spirituality.I think it should lead students to curiosity, interest in culture or human growth is stagnant, now in Web browsers too.
Navigating is necessary, said Portuguese navigators, but the phrase is more ancient, it was the Roman general Pompey, who encouraged fearful sailors with the phrase: “Navigare necesse, vivere non est necesse”, Petrarca in the fourteenth century who transformed in sailing is necessary, living is not necessary.
Fernando Pessoa, to whom some credit the phrase, actually said: “I want the spirit of this phrase for me”, and now we are in time to surf the Web (the internet is only the basis of this platform), but also to look at the confines of the universe and dream of journeys in the earthworm holes, which Einstein-Rosen predicted and astrophysics discovered.
This also means going to deeper seas, in the metaphorical sense, in knowledge, in the arts and in culture, the only consistent weapon against ignorance that passes militancy, not post-truth, I would say is a post-clearing, a phase of obscurantism.
Also in the spiritual sense, the biblical reading, for example, in the gospel of Luke, when sinners already washed their nets and were discouraged from fishing, Jesus encouraged them: Lk 5:4: “Go forth into deeper waters, and cast your nets to the fishing,” Pedro believes and does.
The correct reaction in times of retreats and apparent stagnation
The best attitude is not to stand still, this can lead to laziness and complacency, is to believe and to go forward, in this case a little faith is necessary.
True spirituality goes against the current of pessimism which is not only disbelief in God, but also in humanity.

The mystery and the spiritual

06 Feb

Both physics and mathematics have already surpassed not only the ideal dimensions: the point, the line, the plane, and the cube, by introducing the fractional dimensions which belong to the fractals immersed in the Hausdorff space, but also by the adoption of the fourth dimension.
The pioneering work was done by Charles H. Hinton (post) in A New Era of Thought (1888), previous to the quantum dimension of Werner Heisenberg and the discovery of the Worm Holes in which already imagine intergalactic trips like see in the fictional film Interstellar (2014),  and the film Contact (1997, of the book of Carl Sagan).
Hinton after having a dialogue with Kantian idealism will say about the human sensorial nature: “in the instinctive and sensorial perception of man and nature, everything is hidden, what reflection then brings to consciousness. We can be conscious a little higher than each individual man when we look at men. In some, this consciousness reaches an extreme point, and becomes a religious apprehension. “, That is, it admitted the spiritual aspect (post). 
It is in this dimension above the individual that Teilhard Chardin worked his noosphere, there may be a greater awareness when people work together, that is, obvious on the human plane, but not so obvious on the spiritual plane, it does not mean just being in agreement, but admitting a spiritual sphere, a noon (spirit) sphere, the noosphere.
As it is possible to penetrate this dimension, to make men work spiritually together, this is above prayer or spiritual meditation, in which one rises individually and even today for medical treatment is commendable, but a collective spiritual action.
The interesting thing is to note that both Chardin, who thought of a kind of cosmic consciousness, which was worth a departure from Catholic dogmas (he was a priest), but also the mathematician Charles Hinton seems to be moving towards the fourth dimension, Salvador Dali also spoke of this in his Mystic Manifesto (1951) and in conversations with the mathematician Thomas Banchoff.
Like Hinton’s philosophical discourse, Chardin’s philosophical anthropology in one of his seminal works “The Human Phenomenon” seems to address aspects of the same theme, a spirituality that leads to a larger collective consciousness and to feel the Universe as a body and as part of the Noosphere, approaching that which is substantial from that which is spiritual.
The reason that both Chardin and Hinton were discarded in their time is that they sought to penetrate a mystery, which Einstein also penetrated with physicist Rosen, wormholes are also called Einstein-Rosen Bridge (figure), being consistent with the theory of relativity.
What is beyond the physical, or the metaphysical is not always contradictory to it, but may be the solution to some of the mysteries of nature, 90% of the universe is mass or dark energy, little known, and recent discoveries are huge, see the Higgs particle (incorrectly called God) and black holes with several new discoveries.

 

The rise of idealism and the spirit

05 Feb

The spirit seen outside the Noologia, name given by the Brazilian Writer Mario Ferreira dos Santos for noosphere studies, is pure idealism in philosophy, and spiritual falsification in theology. The influence on contemporary theology can be seen in the work of Karl Ranner, both in Hörer des Wortes (HW) in his Spanish translation Oyente de la palabra (Listener of the Word), and in the spirit of the world, his thesis of The spirit of the World (1967),

This word where despite the influence of Thomas Aquinas and even Heidegger, he does not completely abandon Kant. Francisco Taborda writes about Rahner: “What Rahner does in HW presages all his subsequent theological walk, characterized by the transcendental perspective that implies the presence of an internal philosophy to theology and carries the mark of the anthropological turn of modernity”.

That is, despite to try to reconcile his thoughts with Thomas Aquinas and Heidegger, his main matrix is ​​in “Listener of the Word” (1963), where he states: “If man stands before the God of a possible revelation, if this revelation, should it take place, must take place in human history … etc. “(RAHNER, 1967, p.223).

But discussing theology is complex today, and unfortunately simplification has led to fundamentalism, which is the worst of all tragedies, for God is Omniscient, so it is not simple, for Love is something so complex that no one ever codified it, poets tried. In philosophy.

The culmination of this idealistic attempt was the Phenomenology of the Spirit, practically an attempt to unravel the Trinity, using the in-itself, de-si and para-si categories, but whose concept of self-consciousness betrays it, for the to be beyond oneself, is actually a return to the self of self.

Thus the transcendent God is “dead” to Kant, for it is a pure relation of immanence, which is diagnosed by Hegel (2007, 173), thus generating the idea that the historical God, the same as that of Rahner, denying the aspect absolute, spiritual above the temporal, “the feeling that God Himself is dead” (idem).

Gadamer, in retelling Hegel, reveals this Spirit as an immanence: “It is an immanent progression, which does not intend to start from any imposed thesis, but to follow the self-motion of concepts, and to expose, dispensing entirely with every designated transition from the outside, the immanent consequence of thought in continuous progression. ” (GADAMER, 2000, p.11)  

This isn’ t the Trinitarian Holy Spirit, but a vision of spirit immanent only human.

Thinking and linearity

04 Feb

The linearity of thought is so impregnated in contemporary culture that even expressions such as “a straight man,” “righteousness,” or equivalents become synonymous with fairness, good, and social harmony.
This is more connected to mathematical reasoning than to empirical reasoning. It is no coincidence that the examples formulated by the rationalists of the sixteenth and seventeenth centuries used the triangles as examples of the idea of universals, and even in this case separated subjects from objects, not by chance either Descartes (1596 1650) and Leibniz (1646-1716), were also mathematicians.
For rationalism both ethical and aesthetic ideas, as well as Justice, Virtue and Beauty, must also be objects of the World of Ideas, so a whole construction was made according to this way of thinking that is now in crisis, because the separation produced a Being that is strange to Thing, to the Ens (thins that being), making a pun: the problem of the Being of the Thing (in portuguese make a word sick: Do-ente).
Fundamentalists, having an intuitive basis for contemporary thinking, argue that Being is “spirit”, which has little or nothing to do with spirituality or religion, on the other hand the materialists argue that we are pure beings, to be of nature and thus substance.
The empiricist prior to Kant, the Scottish philosopher David Hume (1711 1776), while admitting that all ideas derive from experience, denied the method with the use of induction: “What is the basis of all conclusions from experience?” (Hume, 1985: 37), or how is the passage from observational statements to universal statements justifiable?
Hegel intended to take this to the spiritual plane in still idealistic Spirit Phenomenology. Although idealism / empiricism could appear to be a complete epistemological system, in 1829 Lobachevsky developed non-Euclidean geometries, then came the hard surfaces (photo) of Rieman (1826-1866) whose generalization takes the dimensions of Haussdorf (1868-1942) and to fractals, who also wrote about philosophy as “Paul Mongré”.
But it is not only the complexity of physics and mathematics, the ontological resumption of being goes beyond logicism and empiricism, it is the ontological resumption. https://philpapers.org/rec/MONDCI
