Wang Yonghuai. (Institute of Automatism, Academia Sinica, P.H.C.) Abstract The effects of Qi from 14 qi-Cong 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 living beings are composed of molecules, study the effects of Q~ on molecules will help us to get a better understand- ing of the biological effects of Qi, viz., the growing effect or killin- ef- fect on bacteria., LiIquid crystal (LC), because it is highly sensitive to the physical en- vironement, was used in the experiment. The ordered alignment of LC molecules is easily disturbed by the variation.of its physical environement. Change In the orientation of alignment means'change in its physical properties. If Q! has any effect on the molecular motions of matter, it will be ob- served on LC easily. I . Experimental Setup A,wedge shaped diphenyl nematic liquid crystal was used in our experiment*. D The top width of the wedge is 10 the bottom width is 300 JA arid the height is 1.3 cm respectively. The wedge is confined between two -lass plates so that the long ax .es of the liquid crystal molecules. are par-,Lllel to the sur- faces of glal~s plates. (f1-.0 A He-Ne laser of power 2 m',,1 was placed 40 cm away from the wedge. Ua- meter of the laser beam spot on the wedge is I 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, iridex of reFraction no) has its plane of polarization perpendicular to the optical axis of LC, i.e. perpendicular to thelong axis of LC molecules, and an the Pl e Of Approved For Release 2000/08/09 CIA-RDP96-00792ROO0200160001-8 larization perpendicular to that of 0 beam, (fig.2) lo Liquid crystal wedge Fig. I LC molecules Direction of optical axis of LC He-Ne Laser 0 beam 0 beam Fig. 2 Screen, In fig.2, are the angles of deflection of 0 beam and E beam respec- tively.

Experiments The first experiment was done at the end of 1983- The subject put his-hand 10-15 cm away rom the liquid crystal, send his Qi from his harA to liquid crystal and the effect of Qi on liquid crystal double refrac- Approved For.Release 2000/08/09 : CIA-RDP96-00792ROO0200160001-8 -2- Approved For Rdleasle 2000/08/09 : CIA-RDP96-00792ROO0200160001-8 tion power i4a,s observed. Among four Qi-Gong amateurs tested, two of them showed quite strong effects. The intensity of the E beam became weaker and weaker while the intensity of 0 beam became stronger and stronger, The most striking effect was given by subject G, the intensity of E beam became so dim that only the central part of the beam spot remained vi- Bible and the Intensity of 0 beam strongly intensified. The intensities of the beams tevovered in one or two-minutes after the subject ceased to. serd his Qi on LC.

No effect on LC was observed. In the next experiment two silicon photocells and two microammeters~ were used to record the changes in spot intensities. A typical result is shown In fig4- Under the Influence of Qi of Amateur T, the intensity of E beam diminished to 75 % of its original value and the intensity of 0 beam increased to 124 3. Discussion When a plane polarized beam. incident upon a liquid crystal making an angle 0 with the optical axis of the LC, the beam will decompose into two components. One component has its plane of polarization parallel to the optical axis of LC and-the other component has its plane of polarization per- pendicular to it. Let the Intensity of the beam be I (Amplitue A, A=12 the Intensities of the parallel beam and perpendicular beam be Id and I_L res-Y pectively. The amplitude of I// is A// and the amplitude of I.L is AjL Then from fig.4a A// -A cos 0. A L =A sin 0. It can easily be-shown that Ie =I Io =I'L If the optical axis of LC rotates through and angle 40 under some extern- al influences, then the parallel and perpendicular components will become A cos (04LO) and A sin (0+.AO). The intensities I and 10 become Ie- 2(s1n 0)(cos 0)1 AO=I e-Ziet 10+ 2(sin 0)(cos O)I.40=IO+AIO 0 The increment 1 0 equals to the decrement I e , and 4 1e/I e =2 tanO 40. In our case, 0=45 0, _kI e/,e=25 %. then &Or-j?o. That means, under the influence of Qi from AmateurT, the optical axis of LC rotates through an angle about 7 0 hence the molecules of LC rotates about 7 0, 4. Additional experiments The molecules of nematic liquid crystal, can rotate in an other waF -- rotate about their z-axis (fig.6). According to the law of double refrac- tion, ne decreses but n 0 remains invariant. As a consequence, the deflec- tion angle of E beam decreses, and the E beam moves upward. Part of the beam moves out of the reception area of the photocell, the intensity of E beam recorded by the photocell decreses. Ap6~dved of I e 0 was 130%, we can calculate that the angle of rotation is approximately 9 Approved For Release 2000/08/09 CIA-RDP96-00792ROOOP00160001-8 A VA All Wt~d ~al axis Fig. 5- Conclusion The effects on M double refraction power induced by the Qi from 14 qi- Gong amateurs were observed, 7 of them showed distinct effects. As control, the effects on IC by 4 non-exercisers were examined, none of them gave any perceivable effects. The vari;tions of the intensities of 0 beam and E beam can be explained by the molecular rotations induced by Qi, though the rotation angles are not very large. Many doctors believe that QA-Gong therapy is merely a sort of psycho- therapy, the so called Qi itself has no therpeuVic effect. Our experiment shows that Q,1,has real,physical effects on non-living molecules. It strong- ly supports the viewpoint that Qi-Gong therapy,is not merely a psychotherapyi, This work has presented at the affiliated hospital of Hai~vaxd Medical College and at the Long Island Jewish'Medical Center, N.Y. in 'September 1985 when the Chinese Qi-Gong Science Delagation visiting U.S..
