The 20 Metaphors for Sea (With Examples) show how sea metaphors can express vastness, depth, mystery, change, and endless possibility.
In Okinawa, Jon Brundan, a visiting scientist and mathematician from the University of Oregon, discussed a striking idea from Alexander Grothendieck, the famous mathematician who used the Rising Sea as a metaphor for mathematics, category theory, approaching problems, and mathematical problems. His quote compares a problem to a nut to crack: a targeted approach uses a direct approach and a tool for attacking the problem, while an indirect approach means soaking the nut in water until its shell is softened and opened.
Likewise, unknown areas and unsolved problems become pieces of land or land areas surrounded by sea; as the rising sea of general progress in theory grows, these areas become increasingly surrounded and eventually inundated, leaving problems solved without targeted action. This general level and level of knowledge show how knowledge is increased through problem-solving, mathematical knowledge, and progress, making an indirect method a useful path toward a solution and solving problems.
