Readers Respond
Keeping SAS Alive
Dear Shawn Carlson, and SAS
Membership,
Recently, as we all know
by now, Shawn our Executive Director, conveyed that the core operation
of the SAS was in dire financial straits. This was most alarming for
me, as a member of this important organization. Here we have a tradition,
being carried on in expanded form, that is over 70 years old. My dear
SAS friends, this is a national treasure of America. It would be in
my opinion, most tragic, if we, the founding membership allowed the
demise of this most valuable asset that helps to culitvate all interested
citizens of the world in the pursuit of scientific inquiry.
Therefore, as I see it, each
and every one of us is responsible to the viable continuance of an organization
which serves as a profound interface between the young just beginning,
the non-traditional students, and the established professionals of the
scientific community. Yes, each of us could make a single emergency
donation to prop up the situation. But if we are really committed then
we will , as each's capacity permits, stand by a monthly allegiance
of a regular donation. Personally, I am committing myself to providing
fifty dollars per month over and above membership dues, and any purchases
from SAS.
If the current membership
as a whole were to average around fifty per month this would be a steady
support to the tune of $600,000 per year. Obviously, this amount would
go a substantial distance in increasing the viability of such an important
non-profit organization to the advancement of scientific awareness,
and knowledge over time. Fifty dollars a month may seem like a lot to
commit for an extended period of time, but when you think of what we
spend ten to fifteen dollars a week on, it is a relatively minor effort
to make for such a good cause.
Carpe Diem!

Dear Averett,
Thank you so much for your
kind letter. We will of course share it with the rest of the membership
in this Friday's E-Bulletin. Nancy tells me that you already called
her to authorize her to bill your credit card. Let's hope that many
of our members will follow your generous lead here.
With highest regards,
Shawn Carlson
Make
Your Own Sodium
The subject article brings
back old memories. I tried esentially the same experiment when I was
in high school. I was never able to recover any of the sodium however.
It would always burst into flame as soon as it was exposed to the air.
Thought about doing it in an inert atmosphere but never got around to
it.
As for stunts we used to
toss small pieces of sodium into hydrochloric acid. Instant salt!

Shawn,
Here are some additional
safety concerns and approach in response to the excellent article "Make
Your Own Sodium":
- In addition to keeping
the sodium hydroxide out of your eyes, also try to keep it off of
your skin - sodium hydroxide will turn the skin oils instantly into
soap before attacking skin cells, so if your fingers feel like they
have soap on them, wash in running water immediately. The easiest
way to keep this from happening is to wear latex gloves (which also
keeps you from accidentally contaminating your work with skin oils).
- Pure sodium generates
a tremendous amount of heat when it reacts, and it is also a prime
candidate for mysterious laboratory fires that will burn your lab
to the ground - so only make enough that you need for immediate consumption
in your experiments, and do not attempt to store it for more than
a few days (unless you want to install a heavy duty automatic fire
sprinkler system in your home lab).
- Sodium hydroxide solution
is safe for disposal down the drain of modern construction. For those
who for whatever reason would rather neutralize it before disposal,
can add an equal molarity amount of hydrochloric acid (aka muratic
acid at the local hardware store) - the resulting chemical reaction
yields a sodium chloride solution.
- Sodium chloride (solid)
can also be subsituted for the sodium hydroxide (solid). During the
electrolysis chlorine gas is generated instead of oxygen, thus a fume
hood is likewise suggested.
warm regards,

A Case of Water Pollution?
Hi,
Thought you may be interested
in this. Attached is a photo of outpouring from a concrete sluice from
a sea cave entrance at the site of a chemical experimental base (closed
in 1950).

The photo was taken by a
couple where I work so I'm not sure if its sewage from Portreath or
something more sinister !! They said there is an uncommonly strong acrid
smell.

Editor's Note: Next
week's issue of Amateur Scientist Bulletin (19 October) will
include a lot of information on volunteer water quality monitoring
programs, plus extensive materials on methods for gathering data on
water quality. -SG
Running
Programs in BASIC
"However, unless you have
an older machine (probably too old to run this product) your computer
isn't likely to have BASIC installed."
Not true! BASIC is alive
and well as "Visual Basic", an application development language for
Microsoft Windows. Thousands of end-users and professional developers
program in Visual Basic every day. In addition, Visual Basic is used
as the extension language in Microsoft Word, Excel, and Access, and
as a consequence many folks have this language on their computers without
knowing it. Excel plus Basic is an especially nice combination for quick
analyses: BASIC for computing that is too tedious in Excel + spreadsheet
for data entry and simple manipulations + built-in graphing.
Separate note: most references
attribute the "A" in BASIC to "All-purpose", not to "Algorithmic".

A
Science Mystery in Atmospheric Pressure
I enjoyed the subject article
in the SAS bulletin very much. This is the level of work that I would
dearly like to see amateurs doing. I realize that Kevin is not exactly
an amateur but with a little help I think amateurs could get involved
in this sort of research. The neat thing is you don't even have to do
any data acquisition just mine the internet for the data. I have worked
with FFTs a lot but have never heard of the Burg algorithm. (It might
have some application to things going on at work.) Maybe I missed it
but I did not see any indication in the article that the phase of the
29.68 day signal had been determined. It seems knowing the phase would
help in understanding its origin.
On a related subject: I have
been interesting in doing an amateur version of some of the work Dr.
Bedard has been doing in infrasonics http://www.etl.noaa.gov/infrasound/
particulary the tornado detection idea. I have the room for an array
of sensors and live in an area frequented by tornados but so far haven't
found the time to do much work on it.

From A New Member
I am a new member to SAS.
I was impressed with what I read of SAS, and the roster of members,
and the dedication of Shawn and Nancy, so decided to become a member.
I must say that it's kind
of disheartening becoming a new member and my first email from Shawn
is seeking additional funding (I thought the email was going to be something
of a science nature). My first thought was 'What kind of group is SAS
if the members aren't that supportive?' Anyways, I am glad to read today
that some members have since made contributions, and I would like to
thank them, and more of us should do likewise.

Shawn's Reply:
Hi Edward,
Thanks for your note. Yes,
I'm sure getting my appeal letter after only having been on board with
us for a few days must have caused some alarm. Actually, you should
know that I haven't gone to the membership very often in the past for
money beyond their dues. You won't be getting these requests every few
weeks, as many nonprofits do.
I think we were on the verge
of becoming victims of our own success. We were doing so well in terms
of publishing newsletters and providing membership services that I think
everyone just assumed we had all the support we needed. I'm glad to
be able to report to you that the membership came immediately to our
rescue when they understood our real situation.
Thanks again and I look forward
to working with you on some great amateur project in the future.
Sincerely,
Shawn Carlson
