Actuarial science belong to mathematics, and in mathematics there are still has many contemplating controversy.
About 300 years ago, people doubt that whether one plus one is equal to two.
Many people think that it is a easy question. It is because that everyone know that the answer is two. It is just like a theorem. Everyone use this equation to calculate other questions, and there are no mistakes. Therefore, these people think they do not need to prove it, because it is a theorem.
But many scientists said that if people cannot prove one plus one is equal to two, it is a false statement. If it is a true statement, we can prove it.
In recent years, jingrui chen, Chinese math scientist use his way to prove it. This way is the best way to prove one to one is two far from now, many people still disagree with it though.
This is the very famous contemplating controversy in math field.
