I think this article is charming. It’s about the failure of a big-science apparatus to detect invisible dark matter. It’s called the Large Underground Xenon dark matter experiment. http://www.nytimes.com/2013/10/31/science/space/dark-matter-experiment-has-found-nothing-scientists-say-proudly.html?hpw
Dark matter, the object which the machine failed to capture, may not even be given to sense experience. “As has become de rigueur for such occasions, the scientists took pride and hope in how clearly they did not see anything. “In 25 years of searching, this is the cleanest signal I’ve ever seen,” Dr. Gaitskell said in an interview.”
It used to be that science was an empirical discourse, and if not purely empirical than at least mathematical. That’s what we wooly humanists were taught to think. I guess what drew my attention to the article was this notion: the clarity of not seeing anything. At some point, empirical science slips into the language of negative theology.
