NEWS:  6-08-11  CHLOROFORM

Current events have drawn attention to the "CHLOROFORM" pages that were posted on this site in 2004. In mid-2006 I removed the links to those pages, but they were still accessible directly from other sites. In 2009 my webhost removed them permanently.

Archived copies are available in the early 2006 snapshots of this site on Archive.org.

NEWS:  10-31-04  UPDATE SOON!!  REALLY, I PROMISE...

I REALIZE IT'S NOW BEEN OVER A FULL MONTH SINCE THE LAST UPDATE, AND I PROMISE SOMETHING NEW IS COMING IN THE NEXT WEEK OR SO.  THE NEXT UPDATE WILL BE, BY FAR, THE LONGEST PROJECT ON THE SITE AND ITS TAKING ME THE LONGEST TO CONSTRUCT.  IT'LL BE WORTH THE WAIT, I PROMISE YOU.  HERE'S A TEASER:

PARTLY TO BLAME FOR THE CHRONIC LACK OF UPDATES IS THAT I'VE BEEN INVOLVED IN A NASA MICROGRAVITY UNIVERSITY TEAM.  WE'RE COMPETING FOR A CHANCE TO FLY ONBOARD NASA'S ZERO GRAVITY RESEARCH AIRCRAFT, THE "VOMIT COMET".  FEEL FREE TO CHECK OUT OUR TEAM WEBSITE AT:

NEWS:  9-19-04  READER EMAILS POSTED

I'VE BEGUN TO POST COPIES OF CORRESPONDENCE I'VE HAD WITH READERS AT THE BOTTOM OF EACH PROJECT PAGE.  I FEEL THIS WILL BE AN EXTREMELY VALUABLE RESOURCE AS I FIND MYSELF TAKING THE TIME TO EXPLAIN THINGS IN EMAIL THAT I SHOULD HAVE PUT ON THE PROJECT PAGES BUT WAS TOO LAZY TO DO SO.

THIS FIRST ROUND OF UPDATES CAME FROM LIGHT RUMMAGING IN MY INBOX, BUT NEW EMAILS WILL BE ADDED CONTINUOUSLY FROM NOW ON.  I'VE TRIED TO ELIMINATE PERSONAL INFO BUT PLEASE CONTACT ME IF YOU WISH TO HAVE YOUR EMAIL REMOVED.

SAMPLES OF THE NEW "READER'S QUESTIONS" FORMAT CAN BE FOUND ON THE DYNO AND ACCELEROMETER PAGES.


 

NEWS:  9-13-04  THOUGHTS ON TABLET PCS

THE LAST THING I WANT IS TO TURN MY 'NEWS' INTO A SILLY DIARY, HOWEVER:

AS OF THIS MONTH I'VE STARTED USING A TABLET PC TO DO SOME OF SCI-SPOT.COM'S GRAPHICS.  I'D LIKE TO BE ON THE RECORD AS SAYING TABLET PCS ARE FANTASTIC. 

I USE IT IN CLASS TO TAKE NOTES; MICROSOFT ONENOTE IS A FANTASTIC PROGRAM.  CHECK OUT HOW IT HANDLES MY CLASS NOTESPHYS 515 NOTES VIA TABLET PC.  THE TECHNOLOGY IS FINALLY MATURE AND IF YOU'RE WAVERING ABOUT THE PURCHASE, I HIGHLY RECOMMEND IT.
 

NEWS:  8-30-04  PROJECT REMOVED

UNFORTUNATELY, I HAVE BEEN DISAPPOINTED AT MANY OF THE EMAILS AND ATTENTION THIS PROJECT HAS GENERATED.  AS MANY LINKS AROUND THE WEB EXIST, I AM LEAVING MY ORIGINAL CHLOROFORM PAGES IN PLACE, BUT REMOVING LINKS FROM MY OWN SITE.  I APOLOGIZE FOR THE INCONVENIENCE, BUT I'M AFRAID THE INTERNET IS NOT MATURE ENOUGH FOR THIS INFORMATION.

DUE TO FINALS AND THE END OF THE SEMESTER, THIS UPDATE HAS BEEN A LONG TIME COMING.  THE SCHEMATICS FOR THE 3D PRINTER ARE NOW AVAILABLE, HOWEVER STILL NO PHOTOS OF THE RESULTS.  I'M AFRAID IT MIGHT BE A WHILE FOR THOSE YET; THE PRINTER STAYED IN MY APARTMENT WHILE I MOVED HOME FOR THE SUMMER.
