I 'm just reading a bit and stumbled over an article on the proof of the 54 year old Kadison-Singer problem. I must admit even the layman terms explanation doesn't help me much. "Srivastava offers a layman's explanation of what he, Marcus, and Spielman have achieved. "We proved a very fundamental and general statement about quadratic polynomials that was conjectured by [mathematician] Nik Weaver and that, he showed, implies Kadison-Singer. The proof is based on a new technique we developed, which we call the 'method of interlacing families of polynomials.'" Read more at: phys.org/news/2013-07-indian-math-conjecture-1950s.htmlThe real stuff is even scarier with "Interlacing Families II: Mixed Characteristic Polynomials and the Kadison-Singer Problem" arxiv.org/abs/1306.3969v3

I just remembered why I hated maths at school.

From the book "EVENT HORIZON" by Steven E. McDonald (also in the movie).
When Dr. Weir is questioned about his Faster-than-Light drive he thinks and answers
"Weir shrugged. "Well, it's difficult to..." He stopped, feeling helpless as the equations glowed across his mind, a pure blend of mathematics and practical physics. One day he had known how to bend space and had then set out to prove it. "It's all math, you see... but..." He trailed off again, still trying to reduce the concepts. He had cracked the sky. Now he had to explain it to these people. "In layman's terms, you use a rotating magnetic field to focus a narrow beam of gravitons; these in turn fold space-time consistent with Weyl tensor dynamics until the space-time curvature becomes infinitely large and you have a singularity..."
and one of the crew answers
Cooper was lunging over the side of his bunk again. "<duck> 'laymen's terms,' what about English?"
