数学概念微积分与几何概念微积分题目：数学概念微积分与几何概念微积分 报告人：单中谦夫妇 （独立学者 四川古梅集动漫科技有限公司） 摘要：当前主流学术界使用的是数学概念微积分，其源于十九世纪法国数学家柯西的柯西极限存在准则，及极限理论的创立。这为微积分注入了严密性。然而，如在十八世纪时人们就能找到“不可分量原理”的解决方式，则无需使用柯西的极限理论。产生的微积分将是几何概念微积分。应用新的微积分，可推出——地球可能并没有围绕太阳公转。这样，新微积分哲学理念让地球公转轨道存在新解。 报告时间：202...

新不可分量原理探秘题目：新不可分量原理探秘 报告人：单中谦夫妇，独立学者，四川古梅集动漫科技有限公司 摘要：不可分量原理是什么？牛顿摆，无损连续传递，多y轴坐标系，平面多y轴坐标系…… 由此可证明“点距信息”的最小作用量存在，以及“点信息”具有六个直线方向；也证明点是组成一切几何单位的唯一最小量，并且满足“点是一个占有位置的单位”的基础定义。这时再用几何哲理知识不可分量最小值去理解“曲直概念”，会发现，那个不可分量的最小值就是点。即：点是组成线、线段、面、体积的唯一最小几何单位，以及唯一...
