Bueno, no comments…

That’s a pretty impressive photo taken from:

No more comments, just beautiful! (You may need to see the photo in a bigger size, so go to the original website)

Only image ever taken of a transit of a space shuttle (Atlantis) and the Hubble Space Telescope (HST) in front of the Sun, during the last repair mission of Hubble, obtained from Florida at 100 km south of the Kennedy Space Center on May 13th 2009 12:17 local time, several minutes before grapple of Hubble by Atlantis.

Transit duration: 0.8s. Transit bandwidth on Earth: 5.6 km. Altitude: 600 km. Speed: 7 km/s (25000 km/h). Length of Atlantis : 35m, length of Hubble : 13m.
Transit forecast (place, time…) calculated by www.calsky.com.

El otro día estaba pensando cómo se hacían esos anuncios con miles de personas…, de dónde las sacan y todo eso. Mi hermanó me recordó este vídeo, en donde se escenifica el desembarco de Normandía con solo tres personas y un montón de efectos especiales. Me ha costado bastante encontrarlo de nuevo, así que he decidido el ponerlo aquí y así, a parte de que alguien pueda verlo, que no es mala cosa, yo no tendré que buscarlo la próxima vez!

Y ya está el listo que todo lo sabe que nos lo cuenta.

El truco de serrar a una persona con una sierra o dividirla en varias partes es uno de los que tiene más éxito en los espectáculos de magia.

El ilusionista americano Horace Goldin fue el primero en dividir a una persona en dos con una sierra.

El ardid consistía en meter en una cabina al compinche, que asoma la cabeza por un extremo, mientras que por el otro aparecían los pies de un contorsionista escondido en un falso fondo.

Los magos recurrían también a otro método en el que usaban a una sola persona. Ese truco se hallaba en la sierra, que contaba con unas hojas que se separaban y ensamblaban automáticamente, para no tocar el cuerpo.

Open Culture bring us a new post that may interest you all:

In case you needed a reminder, we’re no longer living in your grandfather’s world. This video makes that plainly clear. Everything is changing in a blink, and education offers you and your kids the best way to navigate it all. Don’t take it for granted.

Is it a video about the changes in our world from jobs to technology. I remember when being a young guy that once I had a discussion with a friend and we realised that, say, in the XII century you could die in the very, exact world you were born. Nothing would change: the political system, the knowledge, the geography, etc. However, and I am speaking on 1981, we felt that us will die in a very different world, not a shade of the world we were born in 1964. This trend, that we thought started around 1492 with Colon’s travels (ok, ok, some other travellers before meet new places) did take speed afterwards and started really to be faster and faster in XIX century and beyond. When watching this video, you get really dizzy about the speed and the depth of changes that we are facing now and the changes our kids will be going through. Have a look at the video.

The song recorded by The Axis of Awesome shows that you just need 4 chords to be a pop star. Different recordings of “4 Chords” will vary as the band continually updates the song with the latest hits that use the structure. (from cataphract comment in youtube)

Here is the video:

Siempre me han interesado los mapas antiguos, esa forma del ver el mundo que  hoy en dia parece imposible de tener sin recurrir a satélites, ,GPS, etc. Cómo hacian para tener una idea tan precisa del mundo, para al final no estar muy equivocados, es algo que siempre me ha fascinado.

Hoy he decubierto este website, http://www.zb.unibe.ch/maps/ryhiner/sammlung/index.php?group=volume, en donde hay un montón de mapas en alta resolución y puedes ver casi todos los paises del mundo. Merece la pena echarle una ojeada.
