文摘
When a human subject sits beneath a wire mesh, hemispheric torsion pendulum (TP) a rapid-onset series of oscillations at frequencies both higher and lower than the fundamental frequency of the TP have been consistently observed.ObjectiveThis study was designed to replicate and extend prior findings that suggest the human subject effect on TP behavior is due to subject-generated, heat-induced convection currents.DesignEffects on pendulum behavior were tested after draping an aluminized “space blanket” over the subject and by replacing the subject with a thermal mattress pad shaped to approximate the human form.SettingExperiments were performed in a basic science university research laboratory.Main Outcome MeasuresReal-time recordings and Fast Fourier Transform frequency spectra of pendulum oscillatory movement.ResultsThe space blanket blocked, while the mattress pad mimicked, the human subject induced complex array of pendulum oscillations.ConclusionsOur findings support and strengthen previous results that suggest the effects of human subjects on behavior of a torsion pendulum are mediated by body-heat-induced air convection rather than an unknown type of biofield.
