A video worth to be seen: Douglas Adams 2001

Parrots the Universe and Everything 

by

Douglas Adams @ University of California,  May 2001

Transcript available at: http://navarroj.com/parrots/.


I've appreciated the subtle link with the 1991 Christmas Lectures: Growing Up in the Universe by Richard Dawkins.

And just to finish about sustainability, a talk of Prof. Albert Bartlett circa 1995.

Including videos in PDF using pdflatex

The mandatory reference for this topic is: http://pages.uoregon.edu/noeckel/PDFmovie.html

The summary is that, the movie15 parckages allows to produce a PDF files with links to videos and animations. The videos must be located on the same directory as the PDF, and for building pdflatex must be invoked several times (4 in my case). As a result the movie is encapsulated in the PDF file, and in order to view the embedded movie, you need to open it with Adobe Reader or Acrobat.
