Re: revolution! online REAL DATA from lab experiments



Today I was participating in a "poling optical fiber" experiment
at Brookhaven National Laboratory. The purpose was to induce
quazi-permanent optical birefringence. The dielectric material (fiber)
was placed in a strong electric field at several temperatures up to
260 degrees C, kept at the maximum temperature for an hour and
allowed to cool without turning the "voltage" off. It was like
making an electret. Then the fiber was used to modulate light
passing through it. It worked (others did it before) but we must
see if the fiber will still modulate light in the same way a month
or two from now.

Suppose I want to share these data. To this this I would describe
the experiment and produce tables with data. Those who are
interested would analyze the data (plotting the curves, drawing
conclusions, etc., either by hand or by using software with
which they are familiar). What benefits could be derived from
sharing experimental data via eMBL? (See below.)

Hi

Cindy Schwarz here. I am looking for people who are interested in becoming
involved in a new project that I have been working on called eMBL. In a
nutshell eMBL is a way to analyze lab experiments over the internet. Logal
has developed software to make this possible. THESE ARE NOT
SIMULATIONS, THEY ARE REAL DATA. If you want to see a sample go to
http://www.logal.net/eMBLsite/eMBL/default.htm. Don't forget to download
the simplayer before running the experiment. Currently physics is the only
section that has stuff in it. The eMBL site is free for anyone to use.
Eventually all users will be able to upload their experiments and lesson
plans directly, but in this early development stage, we will need to do it
for you.

CAUTION: THIS IS IN DEVELOPMENT. IT WILL RUN ON MAC AND
WINDOWS WITH NETSCAPE 4 AND UP. WINDOWS ALSO INTERNET
EXPLORER 4 AND UP. AT THIS TIME THEY NEED ALOT OF MEMORY
TRY 15 MEG ON EITHER PLATFORM IF YOU CAN TO MINIMIZE PROBLEMS.

What I am looking for now is

1) Anyone who has done an experiment using sensors (CBL or MBL) to collect
data. At this point, motion/force data is preferable (1-d or 2-d), but don't
hesitate to send me something else (as it may help shape the needs of this
project). If you have such data (in Excel preferably) you can send it to me
along with a description of the experiment.

2) If your experiment looks like one that can be included in the site, I
will get back to you for more information like details of the experiment,
pedagogy, lesson plans, photo/drawing of set up etc.

3) Logal is offering a FREE three month subscription to logal.net for a 30
student class for the first 10 experiments selected for early inclusion in
this project. SEND ME INFO BY FRIDAY TO BE ELIGIBLE FOR THE
FREE SUBSCRIPTION!!!!!!!
