EINSTEIN@HOME - Team FreeBSD
A team dedicated to the users of FreeBSD running BOINC under linux compatibility mode, or a native FreeBSD BOINC build. Team FreeBSD is dedicated to users of FreeBSD, but not limited to JUST the users. Anyone with the interest in developing a community of people interested in technology, open standards, NIX or BSD based operating systems are welcome and encouraged to earn credits and share ideas and conversation.

the sound of a gravitational wave
24 May, 2008 17:52
"In thinking about gravitational waves as tools for understanding
astronomical objects, one point that I stress very strongly is that
they cannot be used to form images - GW astronomy cannot be a visual
affair!
Instead, I advocate thinking about them as sound-like: Gravitational waves encode in an aural-like manner the dynamics of the source that generates them. You can almost think of as language-like: The signal that we "hear" encodes information about its source. Our goal as theorists and (eventual) GW astronomers is to understand that encoding, and thus to map those signals we "hear" into a deeper understanding of their sources."
- Equal mass binary gravitational waves:
- Two neutron stars, each of 1 ½ solar masses: gravitational_1.wav
- Two black holes, each of 2 ½ solar masses: gravitational_2.wav
- Two black holes, each of 50 solar masses: gravitational_3.wav
- Extreme mass ratio binary gravitational waves:
- Initially circular orbit, into rapidly spinning black hole: gravitational_4.wav
- Initially circular orbit, into slowly spinning black hole: gravitational_5.wav
- Initially highly eccentric orbit, into rapidly spinning black hole: gravitational_6.wav

HTML, CSS, and RSS feed changes for http://einstein.extracted.org
24 May, 2008 16:33
I was a little bored and cleaned up the HTML and CSS code for our team's EINSTEIN@HOME page. It is now W3C CSS Validated (level 2.1). The HTML still needs some work, but the changes make the portal look more appeasing.
You will find underneath the team's statistics graphs RSS feeds for any team related information that I may find.
The RSS feed URL has changed to: http://emi.extracted.org/rss.php?blogId=4&profile=rss20 This was for a proxy type separation of any other sites that may be used with the application services I use.
Enjoy!

We're a crunching! Welcome two new members!

Welcome Dan: http://einstein.phys.uwm.edu//show_user.php?userid=325617, and Artefact2: http://einstein.phys.uwm.edu//show_user.php?userid=203437
I always kid about computer exhaust, but I tell you - keeping even one computer crunching numbers can make the temperature uncomfortable. For me, much so - wrong side of the sun, and the computers included. I had to turn on my air, as embarrassing as that may be for this time of year.
Remember, water IS wet, and not always the safest way to cool your computers while you crunch. ;)
Again, welcome Dan and Artefact2!

For those of you wondering what the EINSTEIN@HOME Project is:
EINSTEIN@HOME is a program that uses your computer's idle time to search for spinning neutron stars (also called pulsars) using data from the LIGO and GEO gravitational wave detectors. EINSTEIN@HOME is a World Year of Physics 2005 project supported by the American Physical Society (APS) and by a number of international organizations.My name is Andy Wright - the founder, but really the creator of Team FreeBSD. If you want me to add any links, or have any questions or inclinations for such things related to our group (or to just say hi) - send me an e-mail: einstein@extracted.org or Skype name: extracted
''It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure'' -- Albert Einstein
