“Without bold conjectures, great discoveries cannot be made.” This is what the famous scientist Newton once said.

If scientists did not dare to make bold guesses, there would be no current science and technology, and there would be no great discoveries. There is a saying that "nothing is impossible, only unexpected." Great discoveries are often beyond ordinary people's expectations. At the same time, similar famous sayings include Mr. Hu Shi’s “Bold assumptions, careful verification.” Both famous quotes express that only by breaking through limitations and boldly imagining can we make new discoveries.
