Re “using only a cheap effort”, I assume that a few seemingly-impossible problems of the past have turned out to have a simple solution. Though none immediately occur to me.
(Archimedes with measuring the volume of irregular objects - ‘Eureka’ - is not really an example, because he presumably didn’t think it was impossible, merely very hard.)
