What Is Qi?

At a conference of practitioners and scholars of Chinese Medicine held in Australia recently, it was reported that China has, in recent decades, spent an inordinate amount of resources on experiments to determine the existence and nature of Qi. The nub of the report was that China is easing up on this research. The veracity of the claim that these experiments are slowing down for lack of concrete breakthroughs is not confirmed in this article. The quest to define Qi continues, with there being no breakthroughs that we know of.
