Wanderings
“His
scouts will learn science, not tie knots”.
On the other hand,
Ropers Knots Page will show you how to
tie a wide variety of exotic knots.
Bill
Beaty’s Static Electricity and his Not Your Average Construction Project pages contain lots of info, links and DIY projects
to keep you busy during the upcoming long winter evenings.
Use caution, though, as a lot of the projects are sitting
out there in “The Far Side.”
Michael Foster will show you how
to make a Cheap
High Voltage Generator with PVC pipe.
L. Paul Verhage has placed his book Near
Space, a work in progress, on the
Parallax Web Site. It appears to be a good starting
place for those who may be interested in High Altitude Ballooning.
Re-prints of his Nuts & Volts Near Space
column are also included.
Steve Hansen’s the Bell Jar has an article on the history
of the Crookes Radiometer and some
experiments that may be performed with a modified commercial
unit. Also see --- How
does a light-mill work?
The High Voltage Experimenter's
Handbook is a repository for all the bits and pieces that
Jim Lux has been collecting towards
creating a modern version of the classic 1954 work by Craggs
and Meek --- High Voltage Laboratory Technique.
The virtual Sparkmuseum
of John Jenkins hosts his collection of early wireless, radio,
scientific and other electrical items.

to destroy Argentina’s agriculture?
NASA’s
satellites continue to see
a decline in arctic sea ice in 2005.
Increased
output from the Sun, along with emissions of greenhouse gases, might be to
blame for 10 to 30 percent increase in global warming that
has been observed over the past 20 years.
Researchers at the University of Massachusetts have found
that a combination
of cranberry and oregano extract will kill Vibrio

The Far Side
REX RESEARCH is selling a CD of the files that
were archived on their web site. They have been one of the
prime sources for "unconventional" and emerging
sciences and technology. Along with the pseudo science there
might be some interesting files. It might be worth the $13
just to see what is going on in “The Far Side.”
