CAHS GRADUATE SAYS HIS SCIENCE CAREER IS 'A RUSH!'

Oct. 9, 2002 – Dusty plasma?
Many people in the Virgin Islands might say, "What's that, something like Sahara dust?" A small number of knowledgeable engineers and tech businessmen might say, "Oh yes, that's research a few physicists are working on. We can get some great new products out of it." A very small number of scientists might say, "Oh yes, that's a little branch in physics having to do with gases and microgravity and small particles of solid matter, those guys study it in labs."
One of an even smaller number of physicists who study dusty plasma has said, "I don't care what they do with the technology, I just love to do experiments with dusty plasma and see what develops." Virgin Islander Edward Thomas Jr. went on to say, "In the lab I see things that nobody else has ever seen or done before. What a rush!"
Thomas has been home in the islands for a few days, finalizing arrangements for the 10th Workshop on the Physics of Dusty Plasma, to be held in June 2003 at the Marriott's Frenchman's Reef Beach Resort. It's expected that about 80 scientists and 20 engineers will attend the conference, Thomas said; his colleagues have been after him for a number of years to arrange the national conference here.
A fast-growing field, the initial workshop in San Diego in 1986 was attended by 10 scientists, each of whom felt that he alone was working on this topic. The field exploded as industrial implications moved from astrophysics into semiconductors. In 1990 there were between 30-40 papers published on the topic; in 2001, there were 400. This year's third international conference, held in Durban, South Africa, was attended by about125 scientists and engineers; more than 200 "talks" were presented.
The results of experiments are frequently taken by engineers who develop marketable products – in this field, there have been significant implications in astrophysics in, for example, studying the rings of Saturn and Uranus at the National Aeronautics and Space Administration. Research has also resulted in cheaper methods of producing computer chips and better solar panels, even entire rooftop coverings that function as giant photoactive solar panels. Core scientists aren't interested in the products, says Thomas: the engineers pick up the developed technology and run to their companies and to the Patent Office.
Thomas shows a tiny blue-light keychain flashlight – "It's blue light, not a white light with a blue bulb" – that intrigues his small son and friends. "It took 20 years of research to find a way to get green light and blue light," he observed. Sometimes, he said, 10 hours of data may take one to two years to analyze.
Inspiration at CAHS
Thomas, a product of St. Thomas elementary schools and four years at Charlotte Amalie High School, has long been interested in what sort children grow up to become scientists and in attracting more youngsters to science fields.
In his own case, when he was in eighth or ninth grade, a summer spent on Cape Cod with a marine biologist uncle who took him to hang out in his lab sparked the interest. Returning from that, he landed with two CAHS science teachers – Austin Walters and Howard Gumbs – who fanned the spark. Walters taught physics, and "he was my inspiration," said Thomas. Walters, who was at the time teaching physics at the University of the Virgin Islands as well, taught at CAHS using a college textbook, so Thomas reached college with a leg up in training and knowledge. When he visits home, he always looks up those two teachers, and teacher Irose Payne and now-principal Jeannette Smith Barry.
Although he was a lover of science fiction in books and on television – one of his favorite quotes is from "Babylon 5:" "Be terrified and relieved that we have not explained it all" – he credits his uncle and his CAHS teachers with steering him to science.
Thomas, at 34 a tenured associate professor of physics at Auburn University in Alabama where he had earlier earned his doctorate, is also coordinator of the on-campus Plasma Sciences Laboratory, which he says is a dream situation for him. He sets and supervises laboratory work of three graduate students and five undergraduates, and is about to hire a postdoctoral scientist because of the intense workload at the thinking level. In order to obtain funding, the lab performs other research not related to dusty plasma; in his lab, there's an important instability experiment going forward.
"You're trained as a scientist to be flexible scientifically," he said, "to be a businessman, salesperson, a manager, and that way you get grants which allow you to do the best possible science."
Creating Future Scientists
Thomas feels strongly that a community must support its science teachers if there is any expectation of producing future scientists. This includes salary, materials and equipment, and continuing education on the part of teachers. And, he says, it must begin at the elementary level.
In addition to his teaching and research position, he also coordinates a high school internship and teaching opportunities summer research program and is faculty advisor for a professional society of physics students.
When classes visit his laboratory, he says, it's the children from 6th grade on down that are really interested, with first and second graders being the best, most "hands on," most curious and excitable. By junior high age, Thomas said, "something happens to kids that suppresses that curiosity: puberty, peer pressure, something. By high school it's too late" to turn them toward the sciences. And community and school need to recognize that, and plan accordingly. It takes "political will."
The environment of the Virgin Islands, he observed, is a "natural laboratory." So many aspects are covered, from the obvious marine biological sciences to trash disposal, fisheries, and solar and wind power. "Science is living and breathing," he said; "Early teachers can generate great enthusiasm."
When a high school senior graduates No. 1 in his small class, he feels he's tops. But then he enrolls in a college course where all 30 students were No. 1 in their high school. They cannot all continue to be No. 1. As a college professor, Thomas feels some sadness that in his teaching he must cull out some who can't continue to be No. 1s, but it is necessary to teach to the ones who will become the future scientists.
