Movies of plane Couette - tutorial

(latest posts at the top)

Check out Dynamical Systems Magazine: our tutorial is featured, with somewhat misleading abstract — Predrag Cvitanovic 2009-04-28

• still need to finalize the world as seen from upper branch
  • need to include some eigenfunctions
• continuation diagrams showing that solutions (EQBs and TWs) are robust under parametric perturbation
• picture of HKW periodic orbits compared to HKW turbulence. JFG finds this one compelling.
• need to add two slides to conclusions
  • eigenfunctions → control
  • Lagrangian chaos → turbulent mixing (maybe wait?)

• to all: make sure flash pop-ups work in all of your browsers?
  • Mac? (which I do not have)
  • XPwindows Firefox 3.0+ OK
  • XPwindows IExplorer 7.0+ OK
  • Linux Firefox 3.0+ OK
  • manually-tuned Konqueror on OpenSUSE 11.1 OK/JFG
• DONE: more movies of orbits; link to channelflow database and movie page — Predrag Cvitanovic 2009-03-25

English-major editing of tutorial. Mostly spelling, commas, and particles. A couple changes in sentence structure for flow. Changed Herr Turbulence Expert's Question to Objection, since it wasn't really a question. But Objection might be too aggressive, maybe change it back. Changes are obscured in diffs by very long lines of text and white-space changes due to trailing whitespace removal, which my editor now does for greater compatibility with other editors in other svn repos.

Have no objection to “Objection”

a morning's worth of polishing of the tutorial — Predrag 2009-02-26

• finalized the explanation of the translational basis projection in ChaosBook.org/tutorials
• John, if you proofread this as English major (keep Gibson out of it for now), I'll go through the periodic orbits paper.

Firefox version seems OK, but have IExplorer woes: pop-ups OK when run locally, from the files on the computer, but ran from the ChaosBook.org webserver they come misformated, with all toolbars showing. What to do? — Predrag Cvitanovic 2009-02-27 03:07

When I click in “video formats”, the following files do not exist

 (Quicktime .mov, h264 encoding, 18 MB)
 (Microsoft .avi, wmv2 encoding, 22 MB)
 (Xiph .ogg, theora encoding, 15 MB)

thanks! fixed now — Predrag Cvitanovic 2009-02-03 02:47

would be nice to add a narrative to some of the more difficult slides. As an example, here is Robert_Oppenheimer.ogg. It plays right away, embedded in my Firefox on XPwindows. The *.ogg players can be copied from its source file (have not done it yet). Check wikipedia.org/wiki/Ogg, wiki.xiph.org and xiph.org.

To create an *.ogg, I use mswindows 'sound recorder' - that gives me a huge *.wav. file. Then I download OggDropXPd and drag the *.wav into its icon - result is an *.ogg file reduced by a factor of 20. ~~DISCUSSION~~
