Cinco libros para el verano

Alvy de Microsiervos me ha lanzado el meme de libros para el verano (también me ha lanzado el meme musical; veré de hacerlo, pero la música se me da mucho peor). Siguiendo su modelo, yo saco 5 de mi último pedido a Amazon (de ayer, por cierto):

Y le paso el testigo a fernand0, jj, rvr y davidgp. Los demás que quieran, pues adelante también. Están invitados.

Fotos submarinas con el móvil

Pues sí, una funda que se ajusta a gran cantidad de móviles, que te permite sacar fotos bajo el agua y enviarlas a Internet (¿hay cobertura allá abajo?):

WAVECASE transforms your mobile in a few seconds in an authentic under-water camera with MMS-functions. The patented cover is a pattern of a quick «snapshot» at the holidays on beach or at diving, or water sports.

Me la compraría si tuviese intención se sumergirme en aguas gallegas. Hay fotitos.

Vale, a lo mejor en Canarias…

¿Qué más da la ciencia?

Según Robert Park, por una módica cantidad, la sonda Voyager podría enviar valiosa información científica durante muchos años más. Por desgracia, el dinero irá a parar a un tonto viaje tripulado a Marte.

SPACE: VOYAGER 1 REACHES THE LIMIT OF BUSH’S ATTENTION SPAN

It’s been traveling for 28 years and is now 8.7 billion miles from Earth. It just reported that it has entered the region of the heliosheath, where the solar wind begins to dissipate. It may be in this region another 10 years. Its Pt-238 radioisotope thermoelectric generator (RTG) should keep operating until about 2020. When Voyager 1 crosses that final boundary, becoming the first human artifact to enter interstellar space, Earth won’t know. Communications with Voyager will be cut off to save $4.5M of NASA’s $16.5B budget (.025%), for Bush’s Moon/Mars «vision.»

15 respuestas a las tonterías creacionistas

El creacionismo -muy poca teoría, todavía menos ciencia y mucha religión- es una de esas tonterías que intentan pasar por serias. Ofrecen argumentos que demuestra un profundo desconocimiento de biología y evolución. Ahora, Scientific American ofrece en plan resumen las respuestas a los 15 argumentos favoritos del creacionismo.

Science & Technology at Scientific American.com: 15 Answers to Creationist Nonsense — Opponents of evolution want to make a place for creationism by tearing down real science, but their arguments don’t hold up

Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as «intelligent design» to be taught as alternatives to evolution in science classrooms. As this article goes to press, the Ohio Board of Education is debating whether to mandate such a change. Some antievolutionists, such as Philip E. Johnson, a law professor at the University of California at Berkeley and author of Darwin on Trial, admit that they intend for intelligent-design theory to serve as a «wedge» for reopening science classrooms to discussions of God.

Besieged teachers and others may increasingly find themselves on the spot to defend evolution and refute creationism. The arguments that creationists use are typically specious and based on misunderstandings of (or outright lies about) evolution, but the number and diversity of the objections can put even well-informed people at a disadvantage.

To help with answering them, the following list rebuts some of the most common «scientific» arguments raised against evolution. It also directs readers to further sources for information and explains why creation science has no place in the classroom.

Cosas que aprendí viendo el Episodio III

Incluso de un desastre narrativo como el Episodio III: La venganza del tipo se pueden aprender muchas cosas de interés. Yo, por ejemplo, descubrí que en galaxia no hay ecografías. No deja de ser curioso, porque en nuestro propio mundo, tan atrasado que todavía nadie ha ido a Marte y menos ha viajado en un parasegundo al otro extremo de la galaxia, tenemos unas maravillosas ecografías de alta resolución en 4D que quedan la mar de chulas. Vamos, si incluso me han contado que un médico con un simple estetoscopio es capaz de oír dos corazones; eso sí que es un caballero jedi.

Por ejemplo, Adam Fields ha aprendido que en la lengua de Naboo «morfina» y «epidural» se dicen, curiosamente, «luke» y «leia». ¿No es una maravillosa coincidencia? Ahora podremos ver la segunda trilogía sustituyendo mentalmente Luke por «morfina» y Leia por «epidural». Otras cosas que ha aprendido:

1. When the leader says «Everything’s fine, go wait on the LAVA PLANET», be suspicious.

3. Robots with cutesy voices are annoying, not adorable. That goes double for aliens with cutesy voices. Triple for robots with cutesy voices and smoker’s cough.

6. 20 years seems like nothing when you’re ruling the galaxy.

8. Darth Vader is not scarier with an artful allusion to Frankenstein.

Por su parte, Charles Miller también ha aprendido varias cosas:

In a galaxy far, far away, missiles that release funny little robots that try to eat your spaceship are considered far more useful than missiles that, say, explode.

Maybe the Jedi temple should just spend less time on that flashy lightsaber stuff, and more time teaching novices to «Use the Brain.»

Given how only one person made the connection between a pregnant senator and the guy who was living with her, we can assume that people a long, long time ago haven’t yet worked out where babies come from.

Jedi also go from ‘impossible to kill’ to ‘deer in headlights’ whenever it’s convenient, so to ensure success in killing Jedi just make sure you plan to do it in a way that advances the plot.

A Jedi’s power to be unaffected by the heat of several million tonnes of molten rock quite obviously resides in his feet.

‘Because it would be cool’ is sufficient excuse for any abuse – no matter how flagrant – of continuity, the laws of physics, or just plain common sense.

Una buena medida de la maldad de una película es que te deja tiempo de sobra para reflexionar sobre el extraño funcionamiento de la inercia y la gravedad artificial en ese universo.

Fantasía académica

¿A qué estudiante de ciencia no le gustaría que le pasase lo mismo?

Urban Legends Reference Pages: College (The Unsolvable Math Problem)

One Solve me! day In 1939, George Bernard Dantzig, a doctoral candidate at the University of California, Berkeley, arrived late for a graduate-level statistics class and found two problems written on the board. Not knowing they were examples of «unsolvable» statistics problems, he mistook them for part of a homework assignment, jotted them down, and solved them. (The equations Dantzig tackled are perhaps more accurately described not as unsolvable problems, but as unproved statistical theorems for which he worked out proofs.) Six weeks later, Dantzig’s statistic professor notified him that he had prepared one of his two «homework» proofs for publication, and Dantzig was given co-author credit on another paper several years later when another mathematician independently worked out the same solution to the second problem.
