Gotta say, good luck with that effort. Lenat started Cyc 42 years ago, and after a while it seemed to disappear. 'Understanding' the 'physical world' is something that a few -may- start to approach intuitively after a decade or five of experience. (Einstein, Maxwell, et.al.) But the idea of feeding a machine facts and equations ... and dependence on human observations ... seems unlikely to lead to 'mastering the physical world'. Let alone for $1Billon.
