Supper of the ashes
01
Feb
The original name of the work of Giordano Bruno is La cena de las cenizas (in Italian: La cena 
de le ceneri), what he proposes in this work is a conception of the world, if today we see the planet and the whole universe as “our home” , Giordano Bruno was one of the first to see this as well.
Giordano Bruno’s theories far surpassed those of Copernicus, proposed that the sun is simply a star, that the universe may contain an infinite number of inhabited worlds with intelligent beings and animals, member of the Dominican Order, studied St. Thomas Aquinas and developed A different cosmic theory of church thought at the time, and was accused of pantheism and doomed by the Inquisition.
But from a strictly religious standpoint his controversies were as to transubstantiation in the Eucharist, the Trinity, the incarnation of Christ, and the virginity of Mary.
He influenced thinkers like Spinoza and died at the stake with the respect of many.
In his book The Supper of Ashes declared: “The Earth and the stars …, as they dispense life and food to things, restoring all matter which they lend, are themselves endowed with life, to a much greater extent; And being alive, it is in a voluntary, orderly and natural way, according to an intrinsic principle, that they move towards the things and spaces that suit them, “since Galileo was already repaired, Still higher in relation to Giordano Bruno.
It is Ash Wednesday, and it is not bad if we could go beyond hypocrisy and proselytism to actually speak in dialogue, comprehensively both in the religious field and in the ideological field, but the inquisitors survive even though God has nothing to do with it.
Allies and the bloated community

We continue to comment on Spheres I of Sloterdijk in his introduction.
Explaining the bubble influx, Sloterdijk begins to develop his analysis of modernity from the genesis, exploring the Copernican model that is at its origin, to affirm that it is not by chance that “a series of exploratory ruptures have begun, aimed at an exterior devoid of human beings … “(Sloterdijk, 2016, 22), but which did not cease to” produce discomfort as the infinity of the universe “(idem) reflection of the astrophysicist Kepler, protesting the model of Giordano Bruno “there is a non-know -that of terrifying and hidden. “
The image of an explosion on the surface of the Sun, larger than Earth illustrates this passage.
The author also quotes the English physicist and cosmographer Thomas Digges, who in the 1570s had already proved that the theory of the celestial layers was unfounded and “also the calculating image that the Earth was surrounded by spherical vaults” (page 23) Was wrong, but as I said in Pascal’s phrase: “the eternal silence of infinite spaces terrifies me,” and the machinic and rationally explained world was advantageous to the Enlightenment.
It then develops the deliberate greenhouse effect, where its “lack of space wrappings through a civilized artificial world … this is the ultimate horizon of Euro-American technical titanism” (page 25).
After criticizing the policies of progress and ecological destruction, he writes: “In order to make room for the substitute artificial sphere, the remains of a faith in the inner world and in the fiction of a security are exploded in all regions of the old world. The name of a radical market enlightenment that promises a better life, but which, in a first moment, only devastates the immune norms of the proletariat and the peripheral populations “(page 27).
He emphasizes the importance of the ontological resumption and that this is the concern of more contemporary philosophers: “The popular plan of forgetting oneself and the Being operates through a mocking disregard for the ontological situation” (page 28).
Before turning to criticism of idealism and a rereading of Christianity, he points out on page 29 what is the center of the book: “As dwelling always means to constitute spheres, smaller or greater, men are creatures who establish circular worlds and look on Direction to the exterior to the horizon. “

Augmented reality already in schools

Aug
The technology used by game Pokemon Go is already in many elementary
schools, augmented reality has been used to teach mathematics and geometry.
The system uses a made in augmented reality object and the software through a camera does appear on the computer screen a 3D element that students can follow the projection of the image on the screen from the wall.
In real classroom the teacher is second only a flat piece with a cube design, but on the screen of projection appears a 3D geometric element, seeing the constructed image is easier to just use your imagination to understand the geometric operations.
The Bandeirantes Vila Mariana´s College in São Paulo (South Zone) has adopted augmented reality and plan to use the resource in a multidisciplinary project from September.
But the goal goes further with a kind of home treasure throughout the school where the student sees the tablet in code spread across various parts of the school, and can conduct educational activities more playful mood.
The college Dante Alighieri, in the Jardins (West |one of São Paulo city), sent a message to parents alerting the exclusive use of the applications and not others “if demand is not strictly educational”, as published in newspapers of.
An application for adults is the Star Chart, available for Androids and iOS when open he sees aa star letter pointing your smartphone or table to heaven, the application will inform you that the stars or planets you have in the right direction even during the day when the stars are in heaven it is impossible to be seen, and it can extend up to 10,000 light years, so you can see nebulae and distant galaxies.
Let us know Jupiter

The ship’s design Juno, which cost 1.13 billion dollars, which was launched
on August 5, 2011 to explore gravitational and magnetic fields of Jupiter, and to study whether there is water there, you can reach your destination today ( 05/07) at dawn.
Jupiter is 300 times more massive than Earth and is five times farther from the Sun than our planet and completes its orbit around the Sun every 11.8 Earth years.
The first to study it was Galileo, which gave its moons names: Io, Europa, Ganymede and Callisto, and today are called Galilean moons, and supported the Copernican theory that the Earth was not the center of Universe.
Jupiter is the fourth brightest object in the solar system, and our moon one of them, the Sun and Venus; the gas giant is one of the five planets visible to the naked eye from Earth, from Mars, Venus, Mercury and Saturn, and Jupiter, of course.
The ship will disintegrate due to magnetic attraction of Jupiter that is extremely strong, about 2.5 times that of Earth, that is, the feeling of weight someone of 60 kilograms would be 150 kilograms.
In the early hours of Monday to Tuesday the ship entered the Juno orbits Jupiter, “We’re there! We are in orbit! Conquered Jupiter”, said Scott Bolton, the mission coordinator, of the Southwest Research Institute in San Antonio, Texas.
USP conducts a “Scientific Turn”

Oct
With over 300 free activities, today and tomorrow (17 and 18/10) the first edition
of Scientific Turn (Virada Científica) na upset held this year 2015.
The event is a partnership between the Dean of Culture and University Extension (PRCEU) and the Ministry of Science of Brazil, Technology and Innovation will offer, within 24 hours.
According to Eduardo Cooli, general big news event coordinator is in Praça do Relógio (Clock Square), located in center of University City, with circus workshops and performances starring the Circusp, with the intention of creating a larger movement in this square which is quite central.
There shall also Ciencidade Stage, where there will be some attractions like “Do skate the visual arts”, “Cancer: learn to control” and others.All eight USP units will have activities: São Carlos, Bauru, Pirassununga and Lorraine in the capital are included units of EACH (School Of Arts, Science and Humanities) and the Casa de Dona Yaya.
I will be giving a lecture on “Operation and peculiarities of Social Networks” the 17 hours in the Geoscience Institute at 17 hours.
NASA find Earth 2.0

Oct
NASA (North American Space Agency) found the most old cousin of our
planet, with age and very similar structure, the official name is Kepler 452-b, but it has been dubbed Earth 2.0.
It is a little longer and older than our planet, as the Earth has more than 4.5 billion years, the Earth 2.0 has 6 billion, Kepler-452b is about 60% larger than the Earth and needs 385 days to complete one orbit around its star, Kepler 452.
The planet is in the constellation Cygnus, and its solar system is 1400 light years away from ours.
Still may not know exactly what it’s made her solo, but know that it is rocky and quite likely that there is water.
The discovery of Kepler-452b is important, but it is not unprecedented. Last year, US space agency’s astronomers found the first exoplanet with a size similar to that of Earth, the Kepler-186F, as the Earth 2.0 is also a “habitable” zone of a star.
Launched in 2009, the Kepler spacecraft has given the astronomer’s name (Johannes Kepler) to this planet, have been seen almost 4696 candidates for exoplanets while only 1030 have had their existence confirmed.
Is the question we are still alone in this immense darkness of the universe?
