Un vídeo que me ha parecido muy interesante para aplicarlo como profesor para captar el interés de los alumnos, es curiosamente una serie de pautas idénticas a las que propone el autor del vídeo para discutir con "escépticos" del cambio climático antropogénico. Las pautas serían: 1) buscar un marco común de ideas e intereses, 2) Respeto, 3) Proporcionar tu visión de la información y no la información en sí (curiosamente, justo lo contrario de ser objetivo) 4)Trata de encajar la información en su visión del mundo 5) Ofrecer algún tipo de recompensa.

"So yes, Denier, Hawking did actually come up with a novel twist on the black hole information paradox. But is this the solution to the paradox? Hardly. [...]In my opinion, if anyone who wasn’t named Stephen Hawking had proposed this idea, it would be garnering only a small amount of attention, as the idea itself is not fleshed out enough to be anything more than a spark, or a germ of a possibility."
Or is this an example of the media hype surrounding Hawking going nuts?

Se empieza por simular el cerebro de un gusano en un robot de lego y se acaba en Ciudad Permutación. La pregunta interesante es: ¿si el robot se comporta exactamente como el gusano, es consciente a su mismo nivel?

The United Nations (UN) recently released population projections based on data until 2012 and a Bayesian probabilistic methodology. Analysis of these data reveals that, contrary to previous literature, the world population is unlikely to stop growing this century. There is an 80% probability that world population, now 7.2 billion people, will increase to between 9.6 billion and 12.3 billion in 2100.

Science Isn’t Broken
It’s just a hell of a lot harder than we give it credit for.
If you follow the headlines, your confidence in science may have taken a hit lately. Peer review? More like self-review. An investigation in November uncovered a scam in which researchers were rubber-stamping their own work, circumventing peer review at five high-profile publishers.

How Close Are We To Nuclear Fusion?
"Naysayers love to claim that nuclear fusion is always decades away — and always will be — but the reality is we’ve moved ever closer to the breakeven point and solved a large number of technical challenges over the past twenty years."
VideoThe ability to not only utilize but, at will, to create fire -- a source of heat, light and energy that could be applied to a variety of purposes -- was perhaps the key development that led humankind to dominate the plant and animal world, and eventually, all of Earth [...]

Este año, para mi desgracia personal, no podré asistir al mejor evento de divulgación científica del país, Naukas Bilbao 2015. Afortunadamente habrá video streaming del evento. El programa, que comparto,  apunta muy alto.

The myth of the robot job-ocalypse

"Automation has also undoubtedly changed the shape of the job market — economist David Autor, writing in the same journal, documents a rise in demand for low-skilled jobs and highly skilled jobs, and a hollowing out of jobs in the middle. There are signs that the hollow is moving further and further up the spectrum of skills. The robots may not be taking our jobs, but they are certainly shuffling them around."

Todavía no he tenido tiempo de analizarlos detenidamente y he enlazado el post porque contiene un montón de referencia. Pero hay que tener en cuenta que el autor tiene un sesgo obvio en favor de las renovables. Y eso es siempre sospechoso. Aunque lo de los gastos y las ventanas no creo que tenga parangón.
