Some of you young folks been saying to me
“Hey Pops, what you mean ‘What a wonderful world?’
How about all them wars all over the place?
You call them wonderful?
And how about hunger and pollution?
That ain’t so wonderful either. Well how about listening to old Pops for a minute.
Seems to me, it aint the world that’s so bad
but what we’re doin’ to it.
And all I’m saying is see what a wonderful world
It would be if only we’d give it a chance.
Love baby, love. That’s the secret, yeah.
If lots more of us loved each other
we’d solve lots more problems.
And then this world would be gasser.
That’s wha’ ol’ Pops keeps saying.”I see trees of green, red roses too
I see them bloom, for me and you
And I think to myself
What a wonderful worldI see skies of blue, and clouds of white
The bright blessed day, dark sacred night
And I think to myself
What a wonderful worldThe colors of the rainbow, so pretty in the sky
Are also on the faces, of people going by
I see friends shaking hands, sayin’, “How do you do?”
They’re really sayin’, “I love you”I hear babies cryin’, I watch them grow
They’ll learn much more, than I’ll ever know
And I think to myself
What a wonderful worldYes, I think to myself
What a wonderful world
Oh yeah!

Ciudades de América Latina se preparan para el cambio climático

 

Autor: National Geographic en español
Vía National Geographic | Noviembre 16, 2017

El crecimiento demográfico y sus necesidades –energía, agua, alimento– parecen ser los eternos antagonistas de la sostenibilidad. ¿Pueden América Latina y sus ciudades cada vez más pobladas enfrentar el cambio climático sin sacrificar nivel de vida y medio ambiente?El cambio climático ya no es un escenario catastrófico del que echan mano los futurólogos más pesimistas. Hay razones y pruebas de sobra que lo demuestran y que hacen de él una realidad presente y a la que hay que referirnos en gerundio: está sucediendo.Para los países en desarrollo la presión es aún mayor. Por un lado todos los cambios que este fenómeno ocasiona (fenómenos meteorológicos intensos y poco predecibles, como sequías, heladas e inundaciones, que tienen un impacto directo en la producción de alimentos y en las poblaciones) y, por otro, la necesidad de industrializarse e incrementar el nivel de vida de sus habitantes (que suele traducirse en mayor impacto medioambiental) ponen en un dilema a naciones de regiones como Latinoamérica y el Caribe.De acuerdo con el informe Creating Markets for Climate Business, de la Corporación Financiera Internacional (IFC)cerca de 80 % de la población de esta región vive en las ciudades, haciendo de esta la región más urbanizada del mundo.colombia-arttextum-replicacion.jpg
Un área de oportunidad 

Dicen que las crisis son oportunidades para quienes saben aprovecharlas. Para los países en desarrollo este podría ser el caso en esta coyuntura ya que, de acuerdo con el informe, hay siete sectores que pueden marcar una diferencia crucial a la hora de catalizar la inversión privada: la energía renovable, el almacenamiento de energía y la energía solar fuera de la red; los agronegocios, los edificios verdes, el transporte urbano, el suministro de agua y la gestión de residuos urbanos. Si bien, menciona, actualmente se destina más de un billón de dólares a inversiones en proyectos relacionados con el clima en estas áreas, se podrían mover varios billones más en la dirección deseada mediante la creación de condiciones comerciales en mercados emergentes.

Cada vez más gente en la región, especialmente el sector más joven, tiene conciencia ambiental y está proponiendo soluciones verdes para poder mantener un crecimiento económico y social al tiempo que se mitigan los efectos del cambio climático.

El potencial de América Latina es enorme. México, por ejemplo, cuenta con un potencial de 791 000 millones de dólares en inversiones “climáticamente inteligentes” para 2030 (los sectores de energía renovable e infraestructura urbana sostenible ofrecen las oportunidades más notables). En Argentina, el potencial de 338 000 millones de dólares, mientras que en Colombia es de 195 000 millones de dólares.

De acuerdo con muchos especialistas, las ciudades son la mejor opción para sacar a la gente de la pobreza sin arruinar el planeta, gracias a que es más fácil administrar los recursos en una zona contenida.

La manera en la que crezcan las ciudades de la región será fundamental para alcanzar los objetivos de mitigación del cambio climático. En el sector de la construcción se pronostica que los edificios verdes aportarán 80 000 millones de dólares en oportunidades de inversión hasta 2025. Países como Colombia, Costa Rica, México y Perú recientemente adoptaron códigos de construcción verde. Como resultado, se espera que sus edificios nuevos consuman entre 10 y 45 % menos de agua y de energía.

John Wheeler’s Participatory Universe

Autor: Marina Jones
Vía futurism | February 13, 2014

Besides his extraordinary contributions to the field of theoretical physics, Wheeler inspired many aspiring young scientists, including some of the greats of the 20th century. Among his doctoral students were Richard Feynman, a Nobel Prize laureate, with whom he coauthored the “Wheeler-Feynman absorber theory”; Hugh Everett, who proposed the many worlds interpretation; Kip Thorne, who predicted the existence of red supergiant stars with neutron-star cores; Jacob Bekenstein, who formulated black hole thermodynamics; Charles Misner, who discovered a mathematical spacetime called Misner space; Arthur Wightman, the originator of Wightman axioms; and Benjamin Schumacher, who invented the term “qubit” and is known for the “Schumacher compression”. The list could go on.

Wheeler had a reputation pushing his students into a place where logical thought would not necessarily take them. Former student Richard Feynman, to Kip Thorne, declared, “Some people think that Wheeler’s gotten crazy in his later years, but he’s always been crazy![Reference: Princeton] Wheeler was willing to make a fool of himself, to go anywhere, talk to anybody, and ask any question that would get him closer to understanding “how things are put together.” 

LEGACY:

Wheeler believed that the real reason universities have students is to educate the professors. But to be educated by the students, a professor had to ask good questions. “You try out your questions on the students”, he wrote, “If there are questions that the students get interested in, then they start to tell you new things and keep you asking more new questions. Pretty soon you have learned a great deal.” [Reference: Cosmic Search Vol. 1 No. 4]

Wheeler had a fantastic sense of humor. Often he engaged in Koan-like expressions that puzzled and amused his listeners. He saw beauty in strangeness and actively sought it out. He declared, “If you haven’t found something strange during the day, it hasn’t been much of a day.”

Wheeler divided his own life into three parts. The first part he called “Everything is Particles.” The second part was “Everything is Fields.” And the third part, which Wheeler considered the bedrock of his physical theory, he called “Everything is Information.”

EVERYTHING IS PARTICLES:

John Archilald Wheeler was born on July 9, 1911, in Jacksonville, Florida, into a family of librarians. At 16, he won a scholarship to Johns Hopkins University. He graduated five years later with a Ph.D in physics. A year later he got engaged to Janette Hegner. They stayed married for 72 years.

Source UnknownIn 1933 in an application for the National Research Council Fellowship to go to Copenhagen and work with Neils Bohr, Wheeler wrote: “I want to go to work with Neils Bohr because he sees further than any man alive.” Bohr and Wheeler published their first paper in the late 1930s, explaining nuclear fission in terms of quantum physics. They argued that the atomic nucleus, containing protons and neutrons, is like a drop of liquid, which starts vibrating and elongating into a peanut shape when a neutron emitted from another disintegrating nucleus collides with it. As a result, the peanut shaped atomic nucleus snaps into two.

In 1938 Wheeler started teaching at Princeton University. In 1941 he interrupted his academic work to join the Manhattan Project team (which included the likes of Feynman, Bohr and Albert Einstein – with Marie Curie helping lay out the blueprints) in building an atomic bomb. Wheeler considered it his duty to help with the war effort, but the atomic bomb wasn’t ready in time to end the war and save his beloved brother, who died in Italy in 1944.

After the war ended, Wheeler returned to Princeton and taught Einstein’s general theory of relativity, which at a time was not considered a “respectable” field of physics. Wheeler’s classes were exciting – one of his tricks was to write on chalkboards with both hands. He frequently took his students to Albert Einstein’s house in Princeton for discussions over a cup of tea.

EVERYTHING IS FIELDS:

Wheeler co-wrote the most influential textbook on general relativity with Charles W. Misner and Kip Thorne. It was called Gravitation. While working on mathematical extensions to the theory, Wheeler described hypothetical “tunnels” in space-time which he called “wormholes”. He was not the first scientist to think of the possibility of wormholes, or even black holes, but he established the idea. In this regard, it’s worth noting that Democritus, an ancient Greek philosopher, suggested that matter was composed of atoms, which was “mainstreamed” by John Dalton’s discovery of atoms 2000 years later. In 1784, John Mitchell, a Yorkshire clergyman, suggested that light was subject to the force of gravity long before Einstein proved it.

After the publication of the theory of General Relativity in 1916, in which Albert Einstein predicted the existence of black holes, in 1967 John Wheeler named them. Nigel Calder calls them “awesome engines of quasars and active galaxies.” We now have multiple variations of the original concept: charged black holes, rotating black holes, stationary black holes, supermassive black holes, stellar black holes, miniature black holes.

EVERYTHING IS INFORMATION:

Let’s get to Wheeler’s three-part life- story, the last part he called “Everything is Information”.

In the final decades of his life, the question that intrigued Wheeler most was: “Are life and mind irrelevant to the structure of the universe, or are they central to it?” He suggested that the nature of reality was revealed by the bizarre laws of quantum mechanics. According to the quantum theory, before the observation is made, a subatomic particle exists in several states, called a superposition (or, as Wheeler called it, a ‘smoky dragon’). Once the particle is observed, it instantaneously collapses into a single position.

Wheeler suggested that reality is created by observers and that: “no phenomenon is a real phenomenon until it is an observed phenomenon.” He coined the termParticipatory Anthropic Principle (PAP) from the Greek “anthropos”, or human. He went further to suggest that “we are participants in bringing into being not only the near and here, but the far away and long ago.” [Reference: Radio Interview With Martin Redfern]

This claim was considered rather outlandish until his thought experiment, known as the “delayed-choice experiment,” was tested in a laboratory in 1984. This experiment was a variation on the famous “double-slit experiment” in which the dual nature of light was exposed (depending on how the experiment was measured and observed, the light behaved like a particle (a photon) or like a wave).

Unlike the original “double-slit experiment”, in Wheeler’s version, the method of detection was changed AFTER a photon had passed the double slit. The experiment showed that the path of the photon was not fixed until the physicists made their measurements. The results of this experiment, as well as another conducted in 2007, proved what Wheeler had always suspected – observers’ consciousness is required to bring the universe into existence. This means that a pre-life Earth would have existed in an undetermined state, and a pre-life universe could only exist retroactively.

A UNIVERSE ‘FINE-TUNED’ FOR LIFE:

These conclusions lead many scientists to speculate that the universe is fine-tuned for life. This is how Wheeler’s Princeton colleague, Robert Dicke, explained the existence of our universe:

“If you want an observer around, and if you want life, you need heavy elements. To make heavy elements out of hydrogen, you need thermonuclear combustion. To have thermonuclear combustion, you need a time of cooking in a star of several billion years. In order to stretch out several billion years in its time dimension, the universe, according to general relativity, must be several years across in its space dimensions. So why is the universe as big as it is? Because we are here!”

[Reference: Cosmic Search Vol. 1 No. 4]

Stephen Hawking has also noted: “The laws of science, as we know them at present, seem to have been very finely adjusted to make possible the development of life.” Fred Hoyle, in his book Intelligent Universe, compares “the chance of obtaining even a single functioning protein by a chance combination of amino acids to a star system full of blind men solving Rubik’s Cube simultaneously.”

Physicist Andrei Linde of Stanford University adds: “The universe and the observer exist as a pair. I cannot imagine a consistent theory of the universe that ignores consciousness.” [Reference: “Biocentrism: How Life and Consciousness are the Keys to Understanding the Universe“]

Wheeler, always an optimist, believed that one day we would have a clear understanding of the origin of the universe. He had “a sense of faith that it can be done.” “Faith”, he wrote, “is the number one element. It isn’t something that spreads itself uniformly. Faith is concentrated in few people at particular times and places. If you can involve young people in an atmosphere of hope and faith, then I think they’ll figure out how to get the answer.”

CONCLUSION:

Wheeler died of pneumonia on April 13, 2008, at age 96. His whole life he searched for answers to philosophical questions about the origin of matter, the nature of information and the universe. “We are no longer satisfied with insights into particles, or fields of force, or geometry, or even space and time,” he wrote in 1981, “Today we demand of physics some understanding of existence itself.”  [Reference: “The Voice of Genius: Conversations with Nobel Scientists and Other Luminaries”]

Let’s hope that young scientists will continue to be encouraged by these words and will push the boundaries of human imagination beyond its limits, and maybe even find the elusive final theory – a Theory of Everything.

John Archibald Wheeler (1911-2008) was a scientist-philosopher who introduced the concept of wormholes and coined the term “black hole”. He pioneered the theory of nuclear fission with Niels Bohr and introduced the S-matrix (the scattering matrix used in quantum mechanics). Wheeler devised a concept of quantum foam; a theory of “virtual particles” popping in and out of existence in space (similarly, he conceptualized foam as the foundation of the fabric of the universe).

Four Charles Bukowski Poems Animated

Four Charles Bukowski Poems Animated

Author: 
Via Open Culture | May 5, 2014

Article and videos recommended by Karla Castillo from Mexico, collaborator of Arttextum’s Replicación

The poetry of Charles Bukowski deeply inspires many of its readers. Sometimes it just inspires them to lead the dissolute lifestyle they think they see glorified in it, but other times it leads them to create something compelling of their own. The quality and variety of the Bukowski-inspired animation now available on the internet, for instance, has certainly surprised me.

At the top of the post, we have Jonathan Hodgson’s adaptation of “The Man with the Beautiful Eyes,” which puts vivid, colorful imagery to Bukowski’s late poem that draws from his childhood memories of a mysterious, untamed young man in a run-down house whose very existence reminded him “that nobody wanted anybody to be strong and beautiful like that, that others would never allow it.” Below, you can watch Monika Umba’s even more unconventional animation of “Bluebird“:

Without any words spoken on the soundtrack and only the title seen onscreen — a challenging creative restriction for a poetry-based short — Umba depicts the narrator’s “bluebird in my heart that wants to get out.” But the narrator, “too tough for him,” beats back the bluebird’s escape with whiskey, cigarettes, and a policy of only letting him roam “at night sometimes, when everybody’s asleep.”

You’ll find Bradley Bell’s interpretation of “The Laughing Heart,” a poem that advises its readers not to let their lives “be clubbed into dank submission,” to “be on the watch,” for “there are ways out.” “You can’t beat death,” Bukowski writes, “but you can beat death in life, sometimes.” In Bell’s short, these words come from the mouth of the also famously dissolution-chronicling singer-songwriter Tom Waits, certainly Bukowski’s most suitable living reader (and one who, all told, comes second only to the man himself). Only fitting that one inspiring creator delivers the work of another — in the sort of labor of enthusiasm that, too, will inspire its audience to create.

At the bottom the post, you will find “Roll the Dice,” an animation suggested by one of our readers, Mark.

You can find readings of Bukowski poems in the poetry section of our collection of Free Audio Books.
