This paper, through an analysis of the effect of qi (vital energy) on accousto-optic modulation by means of laser, has discovered that qigong effects have the following characteristics:
1. Retardation Effect:
When our qigong master emitted his qi towards the accousto-optic modulator, the optical industry to be modulated did not change immediately until after some time, as shown in Diagram 1:
action order 1 2 3 4
time of day(s) 67.5 46.5 47.5 67.5
average time of delay(s) 57.5
Such effects were also found in other experiments we had made. The same is true, as can be seen from the recorded curve, of the experiment on the impact of qi on laser plane of polarization, performed by qigong master Yan Xin in Qinghau University. All this illustrates that there is a delay for the effect upon the medium acted on by qi. And the time of delay varies with different media and with different qigong master of different capacities. In other words, there exists a threshold for a certain medium when acted upon by qi. The delay in time allows the action to accumulate to such a degree that, once beyond the threshold it will bring about the desired effect.
2. Energeticality and Informationality of Thinking in Mind:
Different thinking in mind will get different results in spite of the same instruments and the same manner of action, as shown in Diagram 2.
action variable relative optical
peak value variable rate intensity instability
no action 0.15
interference 0.60 300% 300%
stabilization 0.075 180%
With interference in mind, the instability of optical intensity increased 300%. Whereas its stability, with stabilization in mind, increased 180%, i.e., its instability decreased 180%. The above shows that thinking in mind is not merely metal activities. It is also characterized as energeticality and informatility. On the one hand, the experimental result is an effective refutation to the opinion that qigong is but a kind of psychological effect and that it exists only if believed in and not if not. On the other, it is also an illustration that qigong is more effective when a recipient believes in it. A qigong master's state of mind bears directly upon the power of his mind emitted qi, its components, and its function as well. Besides, thinking features qi. If a recipient, who also possess a qi field of his own, has resistance in thought, or disbelieves qigong, has own qi field will interfere with that of a qi masters resulting in the increase of his body's reactive threshold to the outside qi information. Consequently, the effects will not be so good. He who believes in qigong and thus whose thinking mind is on the same track as qigong master's, however, will presumably produce resonance effect, reduce the threshold, and absorb the outside qi better. In this case, his physiological functions will be brought into full play, the outside qi signals will be amplified inside his body, and the qi will constantly vibrate and amplify. As a result, under the lashing of the qi, both of his own and of qigong master's, his main and collateral channels inside his body will be relatively clear of blocks and thus he will recover from his disease by various degree. That is why the effects, in the latter case, are better.
3. The Directionality, Localization and Materiality of Qi:
When the qigong master emitted his qi towards the modular, the laser in front of it scattered, which cannot have been due to the condensation of his breath since he was 2.3 meters away and it was summer then. The fact that scattering only occurred in front of the modulator shows that the emitted qi, under the control of the qigong master, is directional and localizable. Able to make laser scatter, qi is probably a matter with characteristics of particles. That's to say, when its density reaches a certain level, qi will make laser scatter.
4. The Mechanism of Qi Acting on the Accousto-optic Modulator:
The optical decreased probably because the modulation system, when acted upon by qi deviates from its central working frequency causing diffractive efficiency to full. The increase of the optical intensity and thus that of the diffractive efficiency are due to the fact that the system, when acted upon by qi, will move toward its central working frequency. And when the diffractive optical intensity becomes stable, that means that a stable ultrasonic field is established inside the acoustic-optic medium, the density of which, in this case, varies steadily and cyclically with the time.
