The hero in this movie is a mathematician. His task is to estimate the cost
for a large war ship Yamato in planning. The proponents of the project made it appear
cheaper. Thanks to Craig Smorynski for pointing out this movie.
It features a second order differential equation and a complicated fitting formula
to calculate the cost of a ship of a given weight. The movie is a good thriller. There
are also some decent war scenes like the tragic demise of the Yamato.
