Sometimes, when learners try their best to solve a complex or creative problem, no matter how hard they try, they still can't solve the problem. At this time, temporarily stopping the active exploration of the problem may play a key role in solving the problem. This suspension is the brewing effect. Brewing effect comes from the discovery of buoyancy law in Archimedes' experiment, which is illogical and spontaneous mutation.

brief introduction

When repeatedly exploring the solution to a problem without any results, putting the problem aside for a period of time will often produce a solution immediately because of some opportunity.

Benzene was discovered by 1825, and its structure has not been known for decades. All the evidence shows that benzene molecules are very symmetrical, and it is hard to imagine how six carbon atoms and six hydrogen atoms are completely symmetrically arranged to form a stable molecule.
