The famous coffee Pícaro in Granada Spain close to the 'pressure' of the city mayor

After more than a decade as a reference to the culture of Granada, Cafe Pícaro in Realejo, he has had to close its doors to the demands of area Environment of the City of Granada. It leaves behind a long story that sounds like Jazz, to magic, poetry readings and storytelling, brilliant references to cultural way. This is the story of a forced dismissal signed by its owner, Gerardo Rosales.

Coffee Stories

Once upon a time Granada was a place called Cafe Pícaro, where we enjoyed theater, concerts, poetry readings, magic, storytelling, exhibitions of painting, photography, workshops in piano, voice modulation and many cultural activities were to reach. Busy place where artists and lovers gave cites the cultural show, chatting under the drug steaming coffee or a beer enjoying a little show until midnight, resulting always short.

We lost a place of management and cultural exchange, the refusal of the council to recognize and grant activity cabaret, valued in any city for diversity that offers its streets promoting their artists and publicizing emerging values.

We enjoyed Coffee Pícaro and its culture for more than a decade, but has been forced to close to the persecution of the City, particularly from the Department of Environment, which meant that any establishment having performances is a Room festivals and as such must be soundproof and placed it against various reports of the Andalusian noting that must be classified in the group of cinemas, theaters and Pub, and against what the Art itself. 33.5 of Decree 6 / 2012, which says: "These limits apply depending on the schedule of the activity in the local consideration".

The activity of Café Teatro, if properly understood, should be considered as cultural offerings for the city, both for its manager and for the administration, their schedules are coffee and their activities are of a theater, performances and shows, with or without musical content, until midnight, must not exceed 85 decibels at most 90 and guarantee them through a limiter in the reproduction chain and understand cities as Paris, Brussels, London or Madrid and overseas, why Why not in Granada, in whose hands are?

No doubt cafe-theater generate diversity on the streets of any city, retaining its visitors with its range of cultural leisure, create jobs, as discussed above promotes its musicians, actors, poets, magicians, etc. Granada increasingly receives more tourism, but tourism step and visit the Alhambra and leaves little to Malaga, Granada does not offer anything to stay a night or two, but thousands of bars as those found in any city.

From here, I call on policy makers to open the city to the culture and the private sector, our streets are dressed in diversity and culture offering not only food, which have spaces where our artists find their audience. The Victoria Cross known today made his first concert at Cafe Rogue went revealing in these spaces as needed in any city.

A flowering Atacama Desert, the other side of Chile's deadly rainstorms

The heavy rains unleashed by a storm that battered northern Chile in March have nurtured life in the world's driest desert and thousands of tourists are marveling at the thriving plant and animal life in the region during the Southern Hemisphere spring.

The rains caused mudslides and floods, killing 28 people and leaving thousands of others homeless.

But the unusual precipitation also transformed the desert, where more than 200 native species of plants now give the arid lands rare scents and colors.

"The Atacama region was punished, but also blessed by the phenomenon of a flourishing desert, something that happens only after the rains, this time brought about by El Niño and climate change," Daniel Diaz, National Tourism Service director in Atacama, told EFE.

"The intensity of blooms this year has no precedent," Diaz said. "And the fact that it has happened twice in a same year has never been recorded in the country's history. We are surprised."

There are only three places in the world where classic deserts bloom: the United States, Australia and Chile.

"It is a unique experience and we take the opportunity to document the ecosystem's dynamics, to observe how flowers live and to catalog them," tour guide Rodrigo Arcos told EFE.

After the devastating deluges in March and additional rain in August, officials said the Atacama region had been able to recover to a large extent due to tourism.

"Tourism gives us a chance to boost the economy and not be dependent only on mining, as it has happened so far," Atacama Gov. Miguel Vargas said.

Atacama, which made headlines around the world in 2010 when 33 miners were trapped underground and rescued 71 days later, is now listed in the Lonely Planet travel guide as one of the 10 major destinations of 2015.

Atacama's residents are awaiting the arrival of about 20,000 tourists eager to see a blooming desert, and experts say the natural phenomenon will continue until November.

Quantum Hilbert Hotel



ABSTRACT

In 1924 David Hilbert conceived a paradoxical tale involving a hotel with an infinite number of rooms to illustrate some aspects of the mathematical notion of “infinity.” 

In continuous-variable quantum mechanics we routinely make use of infinite state spaces: here we show that such a theoretical apparatus can accommodate an analog of Hilbert’s hotel paradox. We devise a protocol that, mimicking what happens to the guests of the hotel, maps the amplitudes of an infinite eigenbasis to twice their original quantum number in a coherent and deterministic manner, producing infinitely many unoccupied levels in the process. 

We demonstrate the feasibility of the protocol by experimentally realizing it on the orbital angular momentum of a paraxial field. This new non-Gaussian operation may be exploited, for example, for enhancing the sensitivity of NOON states, for increasing the capacity of a channel, or for multiplexing multiple channels into a single one.

Although not in the form of a real hotel made of brick and cement, the Czech physical Václav Potoček, Quantum Theory department researcher at the University of Glasgow, now recreated a Hilbert Hotel in quantum version, using a beam of light.

In Hilbert experience, the mathematician explains that in a depleted hotel, but with an infinite number of rooms, new rooms can always be created, and can always be accommodated more guests because the hotel manager could simply "change" all the guests present for a new room and put more guests in rooms that are vacant.

Hilbert even proposes two rules for changing guests.

With one of the rules, it creates a new room and all guests move to the room with the number above the room they are in, freeing the room number 1 for additional guests.

With the other rule, guests move to the room that has the number that is twice the number of the room they are in, creating an infinite number of new rooms and freeing the odd rooms.

In their study, published in the journal Physical Review Letters, the team of Václav Potoček has now proposed two ways to model this paradox - a theoretical and experimental.

Both use the infinite number of quantum states of a quantum system to represent the infinite number of rooms in a hotel.

The theoretical proposal Potoček uses the infinite number of energy levels of a particle in a quantum system, known as potential well, while the experimental demonstration using infinite number of orbital angular momentum states of the light.
