The Crystal Palace and the digital era
10
Sep
Byung Chull Han describes in her that the concepts of telecommunications, she was previous and 
fundamental to the internet, must be reflected with great ontological seriousness, since it is the one that designates the procedural form of densification in numbers of interactions and monetary values, it is calculated that there are ten million e-mails per minute and one trillion dollars a day (VÁSQUEZ ROCCA, 2012).
This high density occurs both in the greater and easier possibility of meeting between agents, either in the form of (relational?) Transactions or in the form of collisions, and this describes in a certain way what resembles the so-called Crystal Palace (idem) .
The Crystal Palace of London in 1850 already housed Universal Exhibitions and also recreation centers dedicated to “education of the people”, this sophisticated architecture, one of the most imposing in the nineteenth century, anticipated a globalized capitalism and intended the total absorption of the world that was produced, long before the digital age.
He quotes Dostoevsky and Walter Benjamin even more frequently, and Sloterdijk (2005) uses them in an article where he uses the idea of Dostoevsky that he finds there the cult of Baal as a consumeristic and hedonistic symbol, where a doctrine of “purposes” as a dogma of consumption.
Sloterdijk makes a connection with Benjamin: “The power of the metaphor of Dostoyevsky’s crystal palace for the philosophy of history is best measured when juxtaposed to Walter Benjamin’s interpretation of the Parisian arcades. The comparison is suggestive because in one case as in the other an architectural form was proclaimed as the key to capitalismo, condition of the world “(SLOTERDIJK, 2005, p. 279).
It will be Byung Chull-Han who solves this duality by establishing that there is always a “mystery” that is unveiled and that this is part of the beautiful and the truth, which is gradually revealed.
It is necessary to think that only 4% of the universe is known, that of the call of baryonic matter, that composed of protons, electrons and neutrons, in addition to some subparticles, dark matter that in part is also baryonic and so-called dark energy, of repulsive action that permeates the entire space, are practically unknown.

The quantum and cosmogony
17
Aug
In addition to quantum physics, there are still mysteries in the so-called dark matter and
dark energy, such as black holes formed with the explosion of supernovae, solar stars with mass up to 10 times larger than a solar star, very bright disappear and give rise to black holes , there are recent discoveries and studies with some clues about them.
Dark energy is about 70% of the universe and dark matter 25%, free hydrogen and helium are 4%, and what we know: sub particles, heavy elements, neutrinos and stars are only 1%, quantum physics helped us to penetrate this mystery just a little.
All this justifies the various cosmogonies built in virtually every culture, Myths, from the Greek mýthos, tell the origin of things (origin of fire, wind, water, plants, animals of man, etc.), by means of supernatural events, but which may rather have real meanings, observations and human experiences before the cosmic mystery.
They usually portray battles, marriages, and marriages between fantastic beings, but they almost always signify some dominion over the forces of nature that the human mind has not penetrated.
When there is an end, not an end, but a goal or a destination about things, beings and facts, there is a cycle called eskaton, forming an eschatology, a complete story with its cosmological end.
In the Christian cosmogony, a special eschatology is the coming of Jesus, his Mary would have conceived in an extraordinary way his son, but the revelation little explored and understood is the speech of Izabel to cousin Maria, who soon to conceive will visit her and Isabel affirms (Lk 1:43): “How can I deserve the mother of my Lord to come to me?” Mary is then the MOTHER OF THE LORD.
The myths about the origin of the world connect cosmogonies and theogonies, Christian theogony can not leave aside this question, the master’s mother, to Teotokos
Quantum physics: origin, paradox and spirituality
16

Werner Heisenberg (1901-1976) was the pioneer physicist responsible for creating a quantum model for the atom, his studies were essential for the
evolution of the area of quantum mechanics with theories related to atoms, cosmic rays and subatomic particles.
In 1927 Heisenberg proposed the “Principle of Uncertainty,” also called the “Heisenberg Principle,” with which he said that it was impossible to measure the speed and precision of the position of a particle. In 1932 Heisenberg received the Nobel Prize in Physics for the creation of quantum mechanics.
Erwin Schrodinger (1887-1961) was an Austrian physicist who created an equation that became known as Schrödinger’s equation, from which he can perceive the changes of the quantum states in a physical system, made it wider than just subparticles.
Famous is his imaginary experiment called Schrodinger’s Cat, a cat is placed in a box with a poison pot together. By quantum physics, he would be alive and dead at the same time.
In 1933, Erwin Schrodinger received the Nobel Prize in Physics for his findings on atomic theory.
Deepak Chopra is an Indian physician who, an ayurveda professor, who does an alternative medicine relating body and mind, Amit Goswami, Indian physicist, parapsychology scholar, has a line of thought called “quantum mysticism”, and the Austrian physicist Tritjof Capra is known for his work “The Tao of Physics”.
But I would add three thinkers who have their thinking related to quantum physics and who I think are more solid in the quantum physics and spirituality relationship: Basarab Nicolescu (1942-), theoretical physicist who has a book Transdisciplinarity: theory and practice (2008), Thomas Francis Banchoff 1938) who had a long dialogue with Salvador Dali about his mystical intuitions, especially about his picture Christus Hypercubus, and, far from the idea of the Cosmic Christ of Teilhard Chardin, which unites theology, anthropology, physics and communication.
Material can help quantum chips
08
Aug
Researchers at the University of Central Florida (UCF) have discovered a type of material that could be
used as a “building block” of quantum chips, consisting of hafnium, tellurium and phosphorus, Hf2Te2P.
According to UFC researcher Madabe Neupane, “Our discovery takes us one step closer to the application of quantum materials and helps us gain a deeper understanding of the interactions between various quantum phases.”
The material has more than one electron pattern that develops within its electronic structure, giving it a range of quantum properties. Neupane says that this material will increase computing power for large volumes of data on new devices and will considerably reduce the amount of power needed for power electronics.
The discovery has already attracted companies that are investing in research, Microsoft for example invested in its project called Station Q, the laboratory that is dedicated to the field of topological quantum computing, and Google has teamed up with NASA in an investment that works with quantum computing and artificial intelligence.
Because quantum phenomena need to be better understood so that electronics are totally replaced by photonics and quantum computation, computational scenario changes tend to change rapidly and continuously.
The discovery of Neupane’s lab is published in Nature Communications, and is a big step forward for this change of scenario.
Absurdity and the evolution of the virtual
28
Jun
The term absurdity used by the American philosopher Thomas Nagel, and serves as the “confusion” 
of Lucien Sfez, but Nagel finds this very human and went so far as to say: “Absurdity is one of the most humane things about us: a manifestation of our more advanced and interesting characteristics, “and this is very humanistic.
We have already posted here the refutation of Jean-Gabriel Ganascia on Artificial Intelligence, although the name may not be its own, the debate heated up with robot Sophia who received the Iraqi citizenship, but in a marketing move, and the use of “virtual assistants voice, “such as Cortana, Siri and Google Now.
Now the Amazon “toy” Alexa starts to enter the home, and it has a greater potential because the universe of Internet of Things (IoT) is growing and will speak.
Returning to Nagel, absurdity is not a hindrance to him, but an affirmation of humanism in his book “What Is It Like to Be a Bat?” (1974), he claims that it might make sense for you to ask yourself how you should feel to be a bat, but it would not make any sense to wonder how you would feel being a toaster.
This means that all this limitation they want imposed on machines is, contrary to what seems an anti-humanism, a rejection of the evolution of the means of production and of knowledge, wrapped with a sentimentality about “the human” in times of inhumanity .
Speaking in evolution of Nagel’s critical view of Darwinism and also of neo-Darwinism, though he sees its usefulness in the scientific debate, to which he states: “One of the legitimate tasks of philosophy is to investigate the limits of even the best developed and most advanced forms. of contemporary scientific knowledge.
It may be frustrating to recognize, but we are simply at the point in the history of human thought in which we find ourselves, and our successors will make discoveries and develop forms of understanding we do not dream about. ” Recalls Teilhard Chardin’s phrase: “the whole future is better than any past”
Small things make a difference?
15
Jun
The answer is yes, though we often imagine that a small act of concord, honesty, or hope can mean a 
naive act, not the same when we think of the physical sense, but everyday thinking remains the mechanic.
Quantum physics and complexity theory have demonstrated this (the name chaos is also misinterpreted because it is the fact that not everything is linear), but it seems more “organized”, more “logical” binary logic of the yes and no, and in this case also has nothing to do with the digital world, only with idealistic thinking.
Also the biblical wisdom and the teachings of Jesus reflected this, in the words of the evangelist Mark, “The Kingdom of God is like a grain of mustard seed, when it is sown on the earth, it is the least of all the seeds of the earth.
When it is sown, it grows larger than all the greenery, and extends branches so large that the birds of the sky can shelter themselves in its shade “(Mark 4: 31-32), who has seen a grain of mustard and saw your tree know this. It is easier and more tempting to follow the current.
But if with small daily gestures we make a difference it gradually changes the culture around us and can spread to other people, just as a vicious circle is difficult to break, a virtuous circle transforms the habits and the environment in which we are inserted.
This is valid for nature, for example for ecological concern and not infrequently we already see many people worrying about the selection of waste, with trees and animals, this will make a difference over the years, it is a new culture that create.
The question of honesty is a reflection of the world of corruption, if we take away small acts of daily corruption we may over the years make corruption something truly heinous, said one activist: “it will be remembered as terrible as slavery.”
It is necessary to apply and be resilient in small acts of daily attitudes of truth and justice.
Chaos and small things
14
Jun
Although chaos suggests something totally disorganized, such as physical and mathematical theory it
means highly sensitive and dependent dynamic systems of their initial conditions, and most systems as they are complex, depend on these conditions (see previous post).
As the system evolves and if we can think of this system over many years, the system that could move “linearly” undergoes profound changes, and this time when the system undergoing changes becomes unpredictable, it is called Lyapunov’s stability period (the above fractal), for example, this calculated period for the sun is approximately 50 million years, it can be calculated for any dynamic system.
At this point complexity theory are united, dynamic systems are complex if seen for long periods, sensitivity of the initial conditions, they can determine the changes in these periods of Lyapunov and Chaos theory, all systems are in constant organization and this can cause great instabilities , depending on the weather.
So small things are unstable over the years and depending on the initial conditions, they are small things like a butterfly wing.
What we can do over the years then is to apply these concepts to human culture, to civilizing processes and to daily conversations and dialogues, thinking about human systems.
Thinking about nature, the planet and indirectly in society, it is necessary not to change the treatment of soil, water, plants and animals, so that in the future a little distant, now not so much, guarantee the stability of the planet, planting of food and an indispensable harmony of nature, in flowers, fruits and beauty.
The theory of chaos is therefore not a theory of the mess, it is precisely the opposition to it, if Francis Bacon and others spoke in the field of Nature, not least his maxim that said “you can not dominate nature without following it “Which means to obey its laws”,
Can a butterfly wing strike cause a tornado?
13
Jun
The so-called butterfly effect, arose from an article by E. Lorenz in 1975 in an
atmospheric forecasting journal and for this reason was a long time concealed as a “phenomenon”.
The first question is this, there is even this article, because it is so little mentioned even more in Brazil since the name of the country appears in the title: “Predictability: Does the Flap of a Butterfly’s Wings in Brazil Set off the Tornado in Texas? “, yes the article does exist.
The other two questions posed by Lorenz himself are: if a single butterfly could generate a tornado, the earlier or subsequent wing beats could also cause the millions of other butterflies as well, and if they could cause they could also avoid them.
What Lorenz proposed in general terms + and that minuscule perturbations do not increase or decrease the frequency of events like tornados, the question he puts in his article is that the immediate influence of a single butterfly can make the presence of a tornado evolve in two different situations, being able in some very early instance to decide its presence or not.
This small event can be fundamental, linked to others, able to modify the regime of the winds and the temperature in a vast region, would spend hours and the meeting of the masses of air can provoke a heavy rain in areas that before was determined sun.
Hence Poincare enunciated in 1908 as “sensitivity of the initial conditions,” but it must be said that the formulation of Lorenz’s chaotic systems distanced itself much from what is called nonlinear systems in mathematics, from the idea that linear is the most common, while unstable or chaotic are unconventional.
Most systems are unstable, and this is fundamental, Heisenberg of whom we spoke in our previous post, said: “quantum physics has defeated the causality and certainty that stable and predictable systems offer us, its phrase is famous:” Physics quantum provided the definitive refutation of the principle of causality. ”
Small actions, in human systems, can also cause huge differences and lead human systems to stability or not
The whole and the part
12
Jun
An essential question of small things is not to imagine them totally unconnected, this is a complex
problem for modern man, because his vision was shaped by idealism to see things in pieces, in isolated parts, without forming a whole.
It is thus for philosophy, for the sciences, for the arts, and even for religion, which sees God as the essence of the “whole,” but almost always segregates it from human realities. A great master and thinker on the subject, his book “The part and the whole”, has just this name was Werner Heisenberg (1901-1976).
The book can be considered his intellectual autobiography, where it makes dialogues with Einstein, Bohr, Planck, Dirac, Fermi, Pauli, Sommerfeld, Rutherford among the most prominent names of the physics of his time, as well as philosophical dialogues with other colleagues.
According to the author in the preface: “Modern atomic physics has shed new light on philosophical, ethical, and political problems. Perhaps this book can contribute to the understanding of the fundamentals of this discussion by the greatest number of people. ”
It is difficult to summarize the ideas of this book, segment it would contradict the proposal itself, but the winner of the Nobel Prize in physics at age 31 (in 1932 therefore) for the formulation of the principle of Uncertainty, said about his book: “I intended to convey, those who are far from atomic physics, an impression of the movements of thought (Denkbewegungen) that accompanied the history of the emergence of this science. ”
The part, however small it is essential to the whole, from the modern atomic and quantum physics, and segments it is to realize the atomic fission, a rupture with nature and man.
The dualism of Kant
06
Jun
Although Kant made a critique of Descartes, he did not penetrate the
question body and consciousness (or mind as many want), but in what he considered the core of Cartesian thought to be the “representation” of things (phenomena):
“All our intuition is no more than the representation of a phenomenon; the things we perceive are not in themselves as we perceive them, nor the relations between them are in themselves as they appear to us;
It is by what he calls a “thing” that can be confused as the phenomenon, but it is the thesis that the human being has a kind of software in his head that interprets the world: the brain is not a container to where they are ” tossed “the objects of the world, he” naturally “processes the culture of the world and sees it in a certain way.
If I lived in our time I would say that it is a painting, not a photograph, and yet I would say that the two are “representations” because it is not possible to conceive the objective reality, only subjective, that is, in the subject’s mind, dualistic
Its kind of dualism is the opposition between the concepts of “derived intuition” on the one hand, and “original intuition”, on the other hand, not an original culture but intuition.
Already the “derived intuition” is, according to Kant, the “sensible intuition” of the human being; and “original intuition” is the “intellectual intuition” that Kant says is divine and not cultural.
Do not be happy the religious, although most understand this as “transcendence” and gave in the “vague” religiosity of today, which states that any intuition is of the “Holy Spirit”, without relation to objectivity, here is the Pure Kant.
The great Kantian problem that will reflect in philosophy, that which Marx said of the old Hegelians, where Man and God are in totally separate realities and without some possibility of ontological interaction, is the “dead” God.
The Kantian thought that I consider the most essential is that:
“And if we take from the center our subject, or even the subjective constitution of the sensibility in general, the whole constitution, all relations of objects in space and time, as well as space and time, would disappear because, as phenomena, they can not exist in themselves, but only in us. ”
When modern physics discovers that space and time are not absolute, Kant’s center of gravity is “swayed” and objectivity is questioned because the subject becomes part of the phenomenon, so it is not only representation, but “ontological” part.
