In mathematics, delta is a symbol representing a change in something. It is mostcommonly used in calculusto indicate the slope of a line tangent to a curve at a given point. Delta can also mean the difference between two values or the derivative of a function at a certain point. Because ...
Bruce Kusse & Erik Westwig, Mathematical Physics: Applied Mathematics for Scientists and Engineers, 2nd Ed. Wiley-VCH, 2006 1. 概念的引入 先考虑一个物理现象: 一个冲量(impulse,短时间内的力),作用在一个短时间内。它的积分是动量。物理过程如下图所示: ∫−∞∞dtF(t)=∫t1t2dtF(t)=∫t1t2dt...

The first two judges I had were mathematics judges. The first one asked me what I would do if I were giving a talk about my project at a colloquium. He asked me to explain one of my results, which I initially did incorrectly (having not looked through the older proof in quite some ...

In mathematics, specifically bifurcation theory, the Feigenbaum constants /ˈfaɪɡənbaʊm/ δ and α are two mathematical constants which both express ratios in a bifurcation diagram for a non-linear map. They are named after the physicist Mitchell J. Feigenbaum. Feigenbaum originally relat...
