A&M prof probes mega-cold

Limited quantities after April 15th.

Texas A&M physicists are ex
ploring a new frontier — the
borderline on absolute zero.
A magnetic cooling appar
atus now makes it possible to
study the behavior and prop
erties of matter at temperatures
within seven ten-thousandths of
a degree above absolute zero,
Dr. Wiley Kirk, assistant profes
sor of physics, says.
This device, which took six
years to make, enables resear
chers to super-cool matter to
temperatures at which it under
goes radical changes in prop
erties, Kirk says. Super-cooling
is a result of reducing the en
tropy, or disorder, of matter.
Reducing the disorder of the
atoms and molecules allows re
searchers to study fundamental
physical properties which would
be impossible to study under the
chaotic influence of heat, he
says.
“This is a frontier area of re
search,” Kirk said. “We are
studying the basic nature of mat
ter — expanding the boundries
of our knowledge.”
Kirk says that at this point he
is not looking for applications
for this new knowledge, but the
new technology could lead to
advances in the microelectronic
industry, new power-
transmission methods, chemical
and physical analytical techni
ques, even space travel — in
navigation, propulsion and
communications.
Only a few other institutions
in the nation have the capabili
ties to conduct such research,
Kirk says.
The magnetic cooling device
used to super-cool such matter
as helium and metals is a
$300,000 multi-stage apparatus,
Kirk says. It cools in several in
terlinked steps, using liquid
helium isotopes, a dilution re
frigerator and a magnetic re
frigerator to isolate and cool the
matter.
Super-cooling produces new
characteristics such as super
fluidity, superconductivity, and
magnetism, Kirk says.
A superfluid is an “ideal
fluid,” he says. It moves without
friction, and therefore has no
resistance to flow. If|
motion in a dosed s;
would move forever.
A superconductivem
has no resistance to flo
flow of an electrical cutraj
making it ideal for d
sensitive elect ionic insln®]

Suspects arrested
in credit card case
United Press International
DALLAS — The arrests of
three women and one man may
crack what police think is a
stolen credit card ring. It is sus
pected that the members of the
ring charged some $9.2 million
in goods in 42 states during the
past 17 months.
The operation just recently
began appearing in Houston,
Dallas, San Antonio and Austin.
During January, 11 bogus
cards were used to purchase
$47,000 in VISA Travel Che
ques at a foreign currency ex
change booth at the Dallas-Fort
Worth Airport.
Monday, Dallas police confis
cated five blank cards and more
than $300,000 in diamonds,
rubies, clothing and electronic
equipment at a north Dallas
apartment.
“We didn’t become aware of
the scheme until Feb. 3, when we
received a call from a travel
agency clerk about a counterfeit
credit-card purchase,” said
W.W. Saunders, a forgery inves
tigator for the Dallas police de
partment.
Grace Ramirez, an agent at
Miller Travel Inc. at the World
Trade Center, said she had a gut
feeling that a woman wearing a
mink jacket and red leather
pants was giving her a false cre
dit card.
Ramirez said the woman
wanted two tickets on the 6:10
p.m. flight to Los Angeles by
way of Houston — a fare that
costs $100 more than a direct
flight.
“I kept insisting that she could
go cheaper by flying direct
(from D-FW)and she kept insist
ing that she wanted to leave
from Love Field,” said Ramirez.
Ramirez took the woman’s
credit card and approved the
number with VISA. But as soon
as the woman left, Ramirez cal
led the phone number the
woman listed as her home in
California. The man]
answered (he phone said*

Texas video champion

United Press Internationa!
DALLAS — World champion
Ben Gold has spent most of his
adolescence listening to ringing
sounds and watching translu
cent colors flash on a dark blue
screen.
Unlike teenagers of another
era, who had similar experi
ences in their dreams or in hallu
cinations, Gold’s trips are real.
At least as real as anything in
the world of video games.
During the last four years,
the “vidiot” has logged an aver
age of four hours a day on Pac
Man, Stargate and Space Invad
ers. On weekends he spends
nearly eight hours a day at local
arcades.
The time has paid off. Earlier
this month, Gold, 16, zapped
