Definition, I believe you can easily find it through a quick online search. I won’t deprive you of this wonderful opportunity. Besides, various professors provide a wide range of scientific definitions on what knowledge and ignorance are.

I can’t recall when and from whom I first heard this thought, but it has stuck with me. I would like to share it with you:
“In the absence of knowledge, we speak of uncertainty, and in its presence, we speak of risks. The absence of knowledge is compensated by faith.” This is applicable in business education, trading, and finance.
