Dr. Jennifer Ruth has published an article on Chinese filmmaker Hu Jie. Here is the link: http://www.propellermag.com/Feb2014/RuthJieFeb14.html. In our correspondence and in her articles that I have read, there is an "ease" to Dr. Ruth's writing, that's how I've put it in the past, I think you will see it here also. Her writing "flows;" it is without "drag" or "friction." Sounds like a description of a physics experiment. She's a great writer.
