Dr. Deissler received his B.S. from Case Western Reserve University, his M.S. from the University of Illinois at Urbana-Champaign, and his Ph.D. from the University of California at Santa Cruz. For his Ph.D. thesis, he introduced the concept of noise-sustained structure, a structure or pattern sustained by the presence of microscopic noise in convectively unstable systems. Since any spatially extended system with nonzero group velocity is convectively unstable at the onset of instability, noise-sustained structure is expected to be very common in nature. In addition to open-flow fluid systems, noise-sustained structure has been found to occur in systems as varied as side branching in dendrites, nonlinear optics, and traffic flow. His three papers on noise-sustained structure [J. Stat. Phys. (1985), Physica D (1987), J. Stat. Phys. (1989)] have been cited over 350 times according to the Science Citation Index (searching for Deissler RJ).
Dr. Deissler has worked at the Center of Nonlinear Studies at Los Alamos National Laboratory, at the National Center for Atmospheric Research, and at NASA. He has lectured around the world on his studies about pattern formation in nonlinear systems, having been invited to a number of international conferences, including three in Japan and four in Europe. In addition to his papers on noise-sustained structure, a few other noteworthy publications during his tenure at the above institutions include: 1) Showing that the classic fluid flow, plane Poiseuille flow, is convectively unstable for all Reynolds numbers greater than the critical Reynolds number [Physics of Fluids (1987)]; 2) showing that stable localized patterns can occur in thin liquid films [Phys. Rev. Lett. (1992) (with Oron)]; 3) showing that stable chaotic localized solutions can occur in spatially extended systems [Phys. Rev. Lett. (1994, 1995) (with Brand)]; 4) showing that universal scaling and universal transient behavior occurs near a Hopf bifurcation [Phys. Rev. A (1987) (with Ecke and Haucke)]; 5) showing that stable localized solutions occur in nonlinear phase equations [Phys. Rev. Lett. (1989) (with Brand); Phys. Rev. A (1990) (with Lee and Brand)]; 6) giving a measure of chaos for convectively unstable systems [Phys. Lett. A (1987) (with Kaneko)]; and 7) showing that low-level external noise can be important even for low-dimensional dynamical systems [Physica D (1992) (with Farmer)].
In 1996 Dr. Deissler started a company (The Ultimate Cosmic Toy Company, Inc.) and created a website (www.zubetube.com) to manufacture and market his invention, the Zube Tube. The Zube Tube consists of an acoustic coil (i.e. a spring) stretched between two plastic resonators which are inserted into the ends of a tube. Vibrations on the coil travel back and forth along the coil creating an echo effect. The vibrations are mechanically amplified by the plastic resonators at the ends of the tube and by the resonant cavity inside the tube. Sounds can be created in a variety of ways, such as vibrations introduced to one of the resonators (e.g. speaking into it) or directly to the spring (e.g. plucking it). One of the most interesting sounds is created by holding the tube vertically and shaking it at just the right frequency to create unusual pulses of sound. These pulses take awhile to build up and they persist for a long time after the shaking stops, thus suggesting a nonlinear nature to the pulses. It turns out that the pulses correspond to torsional motion of the spring.
For the last several years Dr. Deissler has been a lecturer at Cleveland State University. Recently he published a paper in Physical Review E addressing the fundamental question of whether a magnetic field does work on a magnetic dipole. Although this may seem to be a question that should have been resolved decades ago, a thorough review of both the research and educational literature reveals that this question has not been adequately addressed. Consider an atom in a nonuniform magnetic field. Because of the interaction between the magnetic moment of the atom and the magnetic field gradient, the atom will accelerate. While the magnetic field does no work on the electron-orbital contribution to the magnetic moment (the source of the translational kinetic energy being the internal energy of the atom), whether or not it does work on the electron-spin contribution to the magnetic moment depends on whether the electron has an intrinsic rotational kinetic energy associated with its spin. If it does have a rotational kinetic energy associated with its spin, which is shown to be consistent with the Dirac equation, the acceleration of a silver atom in a Stern-Gerlach experiment or the emission of a photon from an electron spin flip can be explained without requiring the magnetic field to do work.
Dr. Deissler has also published a paper in the American Journal of Physics concerning the appearance of objects moving at relativistic speeds. When an object moves past an observer at relativistic speeds it will not simply look contracted in the direction of motion (the Lorentz contraction). In fact, it can look quite distorted. The reason is that various parts of the object are different distances from the observer, and in order for light rays from the various parts to arrive at the same time, they must have left the object at different times. The paper includes photographs of Dr. Deissler on a skate board showing how he would look traveling at relativistic speeds.
