There you go, should anyone happen across annoying tweets in ascii binary, run the mathematica code above to decode... maybe on wolfram alpha.


Can an Einstein Bose Condensate tell us more about the early universe than the Higgs particle will?

Light travels fastest in a vacuum.  A bit slower in air.  2.419x slower in diamond than a vacuum.  In a EinsteinBose Condensate (a cold quantium non-localized blob of overlapping atoms), light practically stops moving.  

So-  I have a few questions without good answers.  What is the speed of light I (or index of refraction)  in a neutron star?   As a black hole colapses, does it turn into a Einstein Bose Condensate before it closes itself off from our universe?   What would the index of refraction of the the very early universe have been as it evolved?

Why does this matter?  I don't know- are gravity waves affected by the index of refraction of the object they pass through?  Could the early universe have had a EinsteinBose Condensate that limited the speed of light and prevented rapid collapse while allowing for speed of light-in-a-vacuum non-localized expansion?

Normally the critical temperature for making a BE Condensate is quite low, but in the early universe density was ~10^95 kg per cubic meter, and that density bumps up the critial temp for einstein bose condensate easily many factors hotter than the temperature of the early universe.   And the early universe doesn't stop being a nonlocalized condensate for quite some time.  

Not being expert enough, I can't tell.   But it seems that the early hydrogen atoms existed before a clear location in space existed for them to occupy.  I don't quite like the idea that the equations break down and therefore can't be trusted... so for me it seems clear that in the begining, there was something like a condensate.

Yellowstone at play part 2

I've made some improvements to the seismogram to sonogram notebook.  will post soon. 

Basically, I improved the sonogram digitizer.  I also I did a wavelet transform to change time isolated events into a frequency table.   The time-frequency tables adds noise that looks something like a numerical moire pattern, but it also appears to be moderately predictive over a short period (perhaps as much as 40 minutes).  

Not really happy with Mathematica's wavelet transforms - seismic  waves are often asymmetric - they spike and then fade |\~-, Gabor wavelets or Mexican hat wavelets and the like -~/|\~- build, spike and then fall off.    I think in some fundamental way I don't quite understand wavelet mathematics or why the implementation is done the way it is.  Implementation seem unusually inflexible, specific and idiosyncratic...  Almost like the science was documented by a unwilling telecomm committee disclosure through a party of moderately baffled lawyers rather than directly from the coherent words, insight and teachings of a brilliant mind.  

 The first go was really just for fun and cranked out after the kids went to be one night.  When I figure out how to better put a good shine on my wavelets,  I'll repost.


The Sounds of Yellowstone

I rather like Yellowstone National Park... fantastic place... well, except for the bear that most regretably attacked and killed Marylyn Matayoshi's husband during my family's first visit.  Still, the park is a beautiful wonder, a special and extraordinary not-exactly-dormant volcano graced with an abundance of life, and perhaps too, an abundance of death. 

In honor of this park, I have something fun to share - and a little bit of code that converts yellowstone webcast heliocorder seismograms into a breif audio clip.  Nothing like the ears when it comes to signal processing, the brain and ears can even out perform a fourier analysis at signal detection.  

My webcorder seismogram to sonogram/sound

(Graphic above: I'm not versed in Java, so that graphic don't sing w/click.)

Here's a rough mathematica notebook that that takes a black/red/blue/green plot heliocorder seismogram and converts it to audio by crunching 24 hours of playback into a minute.   This is my own code, offered freely with the expectation that anyone using my poorly implemented idea to make a drastically improved derivative work will still polietly cite my imperfect original as a great motivator to do better. 

This website has well organized seismogram pictures of the yellowstone region, and if you have mathematica 9 you can pop those pictures into the notebook.  

This is a mathematica notebook file - you probably can't do much with it unless you have mathematica 9:  yellowsound.nb  (yep, that choice limits my potential audience by a factor of 1 in every 94,936.71 visitors or so.)

If don't have mathematica, but want to see the code and run the computable document format version, click here:  yellow  Click play at the very bottom, this code should run as long as you have's computable document format reader installed in your web browser.  The math CDF player is free and runs on a number of OS and browsers.  

Helicorder data image: Feb 20, 2012 from Mammoth Vault Yellowstone National Park.

Sound output after cranking the hurdy-gurdy code:  Sound_1  (download and play)  Note: I had to download before play on Chrome, but not in Safari. 

And Here's a more typical yellowstone sound from an somewhat active chart at YMR Madision River Yellowstone Park Feb 20, 2013:

Sound 2 (download and play, or just image what standing next to a large slowly roiling lava lake might sound like.)

Notes to the ambitious:  I'm personally impressed with what this thing does in 26? lines of code, but the 'frames' for each seismic line don't stay centered through each 15min reading frame line.  Highly active charts overlap, and this code will not discriminate overlap bleed through from from real signal.  Raw data really is the right place to start with a seismo-audio-gram, not from a pre-generated chart.   


The Exotic Fruit Hunters

Here is something intresting:

Sounds like a perfect social-botany-documentary for me.  I look forward to seeing it.

I'm growing a few asian pears.  I grew up amongst wild asparagus, ate tender young ferns bracks, and fresh green spring nettles.  We had easy wild red raspberries but prefered to hunt fantastic wild blueberries the season after fire razed a section of forest, or blackcaps and yellowcaps as well as the formitable thorny blackberry (where a wrong move would rip your sleves to shreds.)

I've wanted to plant a medlar tree just to try a christmas recipe that calls for it from the 18th century.  Medlar is a kind of an open-arse wood-hard apple relative that pretty much has to be fermented to soften it enough for consumption.  Maybe not delicious, but I suspect it would make quite a unique hard cider.


July 2014- Saw the movie a few months ago and enjoyed.   Great watch for gardeners.  Now if only there was a documentry about high-alpine dense wildflower lawns.  I really like the 6" tall, walking on flowers - fairy lawn look... green grass is so 1900's.
