Ronald E. Larsen, Ph.D.
Dr. Larsen is currently the publisher of the web-based political news and commentary site LibertyCalling.com and host of the radio program Liberty Calling Worldwide, which is broadcast over the Internet through Live365.com. He is also a 9/11 researcher. Dr. Larsen is a frequent guest on radio interview programs aired over Republic Broadcasting, Truth Radio, and America Voice Radio networks. In addition, he hosts his own radio interview program, The Liberty Beacon, which is broadcast live over The Liberty Calling Live radio network. In 2003 he began investigating, writing about and talking about 9/11 issues from the viewpoint of career physicist. His news and commentary website address is www.libertycalling.com .
Dr. Larsen received his Ph.D. in Materials Science and Applied Physics in 1973 from Cornell University, employing ultrasonic wave velocity measuring methods to investigate the use of applied hydrostatic pressures of up to 50 million pounds per-square-inch to induce structural transformations in the A-15 high-temperature (16-deg K) superconducting compounds. His doctoral dissertation is based on his work with vanadium silicide, one of these compounds. He holds a M.S. in Physics, awarded to him by Rensselaer Polytechnic Institute in 1960, and a B.A. in Physics, awarded by Wagner College in 1955.
He began his research career in 1958 at Brookhaven National Laboratory (BNL), studying and nuclear radiation enhanced diffusion alloys. Working with other BNL researchers, he helped identify and quantify the details of the differing rate processes governing neutron and gamma ray enhanced diffusion in single-phase copper alloys. Six years later he left BNL and joined the U.S. Army’s Frankford Arsenal. There he studied and identified the reason for the occurrence of catastrophic self-damage of ruby rods when used as lasing elements in giant pulse (Q-switched) laser rangefinders.
From 1972 until 1974 Dr. Larsen was with United Technologies, evaluating the use of laser holography in nondestructively testing adhesive bond in fiber composite propellers and jet engine fan blades and in characterizing vibration mode shapes in rotating parts. During the next three years Dr. Larsen was with TRW, devising ways for nondestructively inspecting carbon missile nose cones and space vehicle components such has lightweight aluminum honeycomb panels and in measuring surface roughness.
Between 1977 through 1982, he managed research team at Southwest Research Institutive developing ultrasonic inspection and sonic holography methods for evaluating nuclear reactor components and devised a method for volumetric ultrasonic inspection of highly curved steel components that used transducers with curvature-correcting lenses.
After leaving SwRI in 1982, Dr. Larsen formed Focal Sonics, a consulting and transducer designing company, and remained there until he joined Reinhart & Associates in 1987 to head up its research program. Some of his accomplishments at R&A include the award and successful completion of Small Business Innovation Research (SBIR) contracts to devise means for counting the number of Kevlar fiber-epoxy composite layers in manufactured battlefield helmets and devise a single ultrasonic testing reference block with a means of continuously varying the size and shape of its flat-bottom hole reflector.
