也谈“关于不可计算问题”——与张本祥先生商榷
|
摘要
实数是不可数的,其涵义是实数的个数严格多于自然数的个数,即自然数集的势为0,而实数集的势为2 0。实数不可数结论是Cantor对数学理论的一大贡献,由此Cantor还解决了长期困扰数学家的难题———超越数的存在。张本祥先生搞混了实数的"不可数"和"不可计算"两个概念,从张文对"不可计算"的模糊定义和实数的不可数无法得到人们关注的地震可否预报的结果。实数是不可数的,但尚无"实数不可计算"的说法,科学在发展,技术在进步,随着信息科学和技术的飞速发展,将来终有一天地震预报成为可能。
Real number is uncountable,which means the number of the real is more than natural numbers.The cardinality for natural number is,and the cardinality for the real number is.The real number is uncountable is draw by Cantor which made contribution to the mathematical theory,then Cantor solved the difficult problem-the existence of transcendental numbers,which puzzles the mathematicians for a long time.MR Zhang mixed the concepts of the uncountable and the incomputable for the real number.It can't the forecasting results of the earthquake from the fuzzy definition for the uncountable and the incomputable of the real number.The real number is uncountable,which is uncertain about the real number is incomputable.As the development of the science and the technology,The prediction for the earthquake will come true in the future.
