A subject of myth and marvel, fear and fascination, lightning
has forever captured the imaginations of all who’ve witnessed
its ferocious beauty. And though centuries of scientific endeavor
have largely dispelled myths and misconceptions about lightning,
knowledge has only enhanced the wonder and reverence thunderstorms
command.
It is this awe-inspiring effect, “the wow-factor,”
one scientist said, that makes lightning a perfect topic for turning
kids on to science. And it was that same savvy grant-writing scientist
who determined that the Texas A&M University System had a
unique, award-winning recipe to sate the National Science Foundation’s
appetite for inciting scientific curiosity.
Drawing from a fortuitous combination of maroon-blooded talent
and A&M System resources that included the planetarium at
Tarleton State University and the Visualization Laboratory at
A&M’s College of Architecture, Jean Ann Bowman, a research
scientist with the Texas Engineering Experiment Station, penned
a proposal for an NSF educational grant to produce a fun-filled
planetarium show dubbed “Enlightening Lightning!”
Bowman’s successful bid drew $179,000 to fund a multidisciplinary,
multi-campus collaboration teaming planetarium and the “Viz
Lab” specialists with scientists from A&M’s Department
of Atmospheric Sciences and the National Severe Storms Laboratory
in Norman, Oklahoma.
The diverse team is now busy creating an informative and entertaining
40-minute planetarium show using lightning to introduce junior
high students to the wonders of earth science, and perhaps in
the process, spark interests in scientific careers. But since
the subject is lightning, the project has another very significant
aim — safety.
“If the kids walk away with anything, it should be how
to save their lives in a thunderstorm,” said Richard Orville,
interim head of the Department of Atmospheric Sciences at Texas
A&M, a nationally renowned authority on lightning, and the
project’s principal investigator. “If I had to put
it in succinctly, I would say it’s about lightning safety,
or how to behave when caught in a thunderstorm.”
The fact is lightning can be quite deadly. According to statistics
compiled by the National Oceanic and Atmospheric Administration,
between 1959 and 1990, an average of 93 deaths and 257 injuries
were attributed to lightning each year.
To tackle the NSF-funded project, tasks were divvied among the
disparate players. Orville and his colleague, Ted Mansell, a research
scientist with the National Severe Storms Laboratory, were charged
with developing the scientific portion of the program. Former
Texas A&M students, Michael Hibbs, director of the Tarleton
Science Planetarium, and Larry Barr, the assistant planetarium
director, were responsible for guiding the project team through
the highly specialized world of planetarium show production. The
actual nuts-and-bolts portion of the project — developing
the script, filming, animating and assembling the visual elements
of the planetarium show — was assigned to graduate visualization
science students Sarah Fowler, Luke Carnevale and Jeff Alcantara.
Together they worked under the direction of Donald House, a professor
of architecture and Viz Lab instructor who specializes in computer
graphics, 3-D modeling and simulation.
Completing the team, not counting the film crew and troupe of
actors who starred in the video portion of the show, are two more
former A&M students, Victor Van Scoit, a visualization sciences
graduate student, who honed the script, and Rebecca Miller, a
meteorologist from NBC affiliate Channel 5 in Dallas/Fort Worth.
Miller, who also teaches television meteorology at Texas A&M,
narrates portions of the show and appears in the video segment
as a TV weatherwoman.
“The thing that has impressed me is how people from such
diverse backgrounds can cooperate to produce something which will
be very beneficial to the public,” Orville said of the group
who knew little, if anything, about one another prior to the two-year
project.
The storyline follows a family of four on a picnic that is interrupted
by a thunderstorm. As they huddle against the storm they talk
about lightning and the somewhat bumbling dad asserts several
misguided opinions and old wife’s tales about lightning
that are dispelled or clarified throughout the presentation.
Miller shares the instructional segments of the presentation
with an animated electron, “Sparky,” that was created
by Carnevale.
“Sparky is an electron that lives up in the clouds and
jumps from molecule family to molecule family trying to find the
one he belongs to,” explained Fowler of the show’s
comic relief. “Sparky was stripped off of his molecule by
a charge in the cloud and he’s trying to get home.”
“He’s kind of the quirky, funny little science guy,”
House added. “He explains a lot of the science.”
In addition to “learning a lot about lightning,”
the visualization team is discovering the unique challenges involved
in producing a multi-media planetarium show.
“The whole concept of a planetarium show is that you have
to develop it in a way that the audience feels totally immersed.
Everything is projected on a dome that completely surrounds them,”
Hibbs explained. “It is much different than a movie. The
audience sits underneath the dome and things are going on all
around them so they feel like a part of the show.”
Other components of the show’s multi-media experience include
Alcantara’s vector-based animations — stars, cloud
formations, rain, lightning and even Ben Franklin’s kite
— beamed from the planetarium’s digital star projector,
and seamless 160-degree full-dome slide projections featuring
a sampling of Orville’s extensive collection of lightning
photographs.
The planetarium project is breaking new ground for A&M’s
visualization laboratory, which has earned a reputation for producing
technically savvy digital artists and animators who are sought
after by Hollywood’s elite special effects and animation
studios. And according to Hibbs, the presentation — with
its daytime setting, extensive use of videography and animated
character, Sparky — is extremely innovative and quite extraordinary
for a planetarium show.
“Working with the visualization lab and the meteorology
department has been absolutely fantastic,” said Hibbs, who
will soon be receiving the project from the Viz Lab to begin final
production and what he called “choreography” of the
multi-media presentation. If all goes according to plan, he said,
“Enlightening Lightning!” will begin dazzling future
scientists in August 2004. But still eight-months away from the
show’s premiere, Hibbs has his eyes on the next collaboration
with his Aggie teammates.
“Next time,” he said, “we’ll do tornadoes.”
