Boiled frog in warm water

Boiled frog in warm water is a "boiled frog experiment" conducted by scientists at Cornell University in the late 19th century. The philosophy is that quantitative change to qualitative change, that is to say, the accumulation of quantity to a certain extent will lead to essential changes. The implication is that the change of the environment can determine your success and failure. Too comfortable environment often contains danger, and you should always be vigilant in the superior environment.
