“用规尺三等分任意角”这一个不成问题的问题,本通报已经登过几次启事说明这是一个已经证明“不能”的问题,忠告一些同志不要浪费宝贵的精神企图“能”了.启事登了以后,“三等分角”的稿件还是源源而来,我们虽然对每一稿都作了答复,但认为对这样的问题彼此白费了许多精力和时间,殊不值得.就来稿的情况看:有些同志是不知道这个问题已经证明“不可能”了;也有人明知道了而偏不相信;还有人想了一个方法,他自己认为是对 “This is a non-issue of using the ruler to trivialize any angle.” This notice has been issued several times. This indicates that this is an issue that has been proved to be “cannot”. Advise some comrades not to waste valuable spirits and try to “can”. After the enlightenment was announced, the manuscript of the “trisection angle” still came from a source. Although we have answered each draft, we think that it takes a lot of effort and time for such problems. It is not worthwhile. The situation looks like: Some comrades do not know that this problem has proved “impossible”; others also know it clearly but they do not believe it; others still think of a method that he himself thinks is right.
