The Latin maxim ignoramus et ignorabimus, meaning "we do not know and will not know", stood for a position on the limits of scientific knowledge, in the thought of the nineteenth century. It was given credibility by Emil du Bois-Reymond, a German physiologist, in his Über die Grenzen des Naturerkennens ("On the limits of our understanding of nature") of 1872.
Novel mathematical research for quantifying and predicting uncertainty in design models
phys.org, Jan 2015
...engineers have come to rely on extensive testing to verify their modeling results—a repetitive process of design, test, verify, re-design, re-test, re-verify that can add years to the development process.
DARPA's Enabling Quantification of Uncertainty in Physical Systems (EQUiPS) program aims to solve this problem by developing the mathematical tools and methods to efficiently quantify, propagate and manage multiple sources of uncertainty.

"[Current technologies] methodologies can now handle forward problems for a small number of uncertain parameters, but they still can't handle more complex, extremely high-dimensional industrial physical systems and [he goes on]..."
"Dealing with the 'curse of dimensionality' where the associated computational cost grows exponentially as a function of the number of random variables remains a major challenge in simulation and design under uncertainty."
