51-year-old Lu Xi'an, a company should phase is construction worker who lives off South Street Wolong East Lane, junior middle school education. Spare time likes to study math problems, he had raised questions about pi, and their views have been published in the journal.

Spring Festival this year, he found the ancient Greek Internet three geometric problems.
■ proven, crack does not hold

■ research challenges are interested in is a good thing
Lu Ying-phase method has been used a dozen, but most are not feasible, in April of this year, thinks he finally has the right solution. Lu should be relative,[link widoczny dla zalogowanych], said he thought problem solving is: first, drawing an arbitrary angle AOB, the AOB of the right angle is divided into three equal parts chord AB, and then arc AB into two equal parts, and finally proved by the final third principle of plane geometry minutes of arc on the arc, arc trisection, the horn of thirds. Papers should be sent Lo phase once, but several universities and colleges are not back.
However, angle trisection ruler was Through the Internet search found that, even if the angle trisection ruler was

■ three world-class problem,
Department Director,[link widoczny dla zalogowanych], the first secondary school in Xi'an, said Yuan Qin Qin, Lu should solve mathematical problems compared dedication to admire. She felt that ordinary people should be more usual mathematical knowledge to real life, the study also should be based on the premise of real life.
Luoxin Bing said that in the history of mathematics, indeed there had been some ordinary people have made outstanding contributions to those who are interested in research problems is a good thing. He suggested that studying math puzzle lovers should be selected in one direction, and then do a comprehensive understanding of the subject, and to have the necessary theoretical knowledge, it will take many detours less.

12 月 3 afternoon, Xi'an, the first secondary school math teacher to help Lu 4 are verified to be his problem-solving methods. Lu should be in the demonstration phase, the teachers pointed out that his problem-solving thinking is correct, but there are step is to use the ruler to do in a straight line outside the designated line parallel to the line, and this is not possible, Lu should be compared Although it has been out, but no theory can prove its existence.
