Mathematicians think abstract tools from a field called symplectic geometry might help with planning missions to far-off moons and planets.

“Sten’s math problems are really great because he tailors them to current NASA events,” said Todd Toth of the Office of Education – Space Science Liaison at NASA Goddard.

To construct a warp drive, we would need negative mass, which doesn't appear to exist in the universe and would violate everything we know about motion, momentum and energy.

In this paper, we introduce a new concept of a generalized analytic Feynman integral combining the bounded linear operators on abstract Wiener space. We then obtain some Feynman integration formulas ...
