Mathematicians and physicists are trained to always identify the boundaries and operating constraints, while solving a problem.
And yet, the best ones perhaps didn’t pay any heed to those boundaries.
They started from first principles.
The minute you start your problem with identifying the boundary, you have closed some doors. Closed some perspective. Perhaps closed your mind too.
“We only have this much money”
“We don’t have more than these people”
“This technology doesn’t exist”
“No one has done this before”
“We have never done this before”
The best solutions never defined the starting boundaries.
They didn’t even acknowledge their existence.
