Applied Physics Division
Studies in acoustics, optics, thermodynamics, and energy transfer. Recent public work has concerned measurement technique and the design of repeatable classroom demonstrations derived from bench experiments.
Studies in acoustics, optics, thermodynamics, and energy transfer. Recent public work has concerned measurement technique and the design of repeatable classroom demonstrations derived from bench experiments.
Testing of material properties under repeated load, and fabrication of prototype components in the laboratory's machine and wood shops. A long-running fatigue study is currently in internal review.
Design, calibration, and maintenance of the laboratory's measurement apparatus. The group also prepares simplified instrument plans for use in secondary-school laboratories.
Numerical analysis, data reduction, and record-keeping systems in support of the other divisions. The group maintains the laboratory's internal computing facilities.
Observation and data collection conducted away from the main facility, including environmental measurement and acoustic survey work. Site reports are filed with the documentation group upon return.
Preparation and archival of technical notes, site reports, and the annual public summary. The group administers the internal review process on behalf of the Director of Research.
A number of active investigations are not described publicly. The laboratory does not comment on work in progress, and requests for information about unlisted projects will be declined.
Procedure
All public releases follow the same path: results are reproduced within the originating division, reviewed by the internal board, and prepared for release by the documentation group. The Director of Research approves each release.
This process is deliberate and occasionally slow. The laboratory considers the delay a fair price for accuracy.
