Open AI Summary
This document, labeled SG1E, discusses an experiment conducted by researchers from Tsinghua University and the Institute of Automatism, Academia Sinica in China. The experiment aims to study the effects of Qi, a concept in traditional Chinese medicine, on the molecular motions of liquid crystal. The researchers observed the effects of Qi from 14 Qi-Gong amateurs on the double refraction of liquid crystal, and found that 7 of them exhibited positive effects. They introduced two types of rotations of liquid crystal molecules to explain the experimental results. The researchers used a wedge-shaped liquid crystal confined between two glass plates and a He-Ne laser to conduct the experiment. The paper also explains the properties of liquid crystal and how it is affected by changes in its physical environment.

Abstract
The effects of Qi from 14 Qi-Gong amateurs on the double refraction of
liquid crystal were observed, 7 of them exhibited positive effects.
Two types of rotations of liquid crystal molecules were introduced to
explain the experimental results.
The purpose of our
investigation is to study the effect of Qi on the
molecular motions of matter. As all

the orientation of alignment means change in its physical properties.
If Qi has any effect on the molecular motions of matter, it will be ob-
served on LC easily.
1. Experimental Setup
wedge shaped diphenyl nematic liquid crystal was used in our experiment.
The top width of the wedge is 10 the bottom width is 300 and the height
is 1.3 cm respectively. The wedge is confined between two -lass plates so
that the long axes of the liquid crystal molecules are patllel to the sur-
faces of glass plates. (fig.t)
A He-Ne laser of power 2 mW was placed 40 cm away from the wedge.
meter of the laser beam spot on the wedge is 1 mm.
Since liquid crystal is double refractive, an_ incident light beam on LC
will be decomposed into two beams in the crystal. The ordinary beam (0 beam,
index of refraction no) has its plane of polarization perpendicular to the
optical axis of LC, i.e. perpendicular to the long axis of LC molecules, and
