then so is the curve x(−t), as is easily verified by direct computation. (Note that d/dt(x(−t)) = ẍ(−t), since the two derivatives pull out two minus signs.) In terms of trajectories in phase space, we note that dx(−t)/dt = −ẋ(−t). This means that the momentum of the particle along the time-reversed trajectory is the negative of the momentum along the original trajectory. We may therefore formu...
متن کاملFuzzy Set Theory - a Playground for Mathematicians
When Zadeh first introduced the notion of a fuzzy set, it was laughed away by the ruling caste of 'serious' mathematicians and logicians. Driven by ignorance, the main reason for it was probably strategic: as fuzzy set theory touches upon the very building block of mathematics, it might be better to deny it than to risk being taken out of business. Even the ample practical realizations had no e...
متن کاملWater Flooding Performance Evaluation Using Percolation Theory
Water flooding is a well-known secondary mechanism for improving oil recovery. Conventional approach to evaluate the performance of a water flooding process (e.g. breakthrough and post breakthrough behavior) is to establish a reliable geological reservoir model, upscale it, and then perform flow simulations. To evaluate the uncertainty in the breakthrough time or post breakthrough behavior, thi...
متن کاملTheory into Profit: Microsoft Invests in Mathematicians
698 NOTICES OF THE AMS VOLUME 45, NUMBER 6 A t a time when many companies have scaled back or eliminated their research efforts, Microsoft Corporation is betting millions on the notion that funding its own research will pay off. And it can afford the gamble: the company’s revenues reached $11.35 billion in 1997. Although Microsoft will not disclose the budget for its think tank, Microsoft Resea...
متن کاملQuantum Field Theory for Mathematicians: Background and History
This course is intended as an introduction to quantum field theory for mathematicians, although physicists may also find some of the material here to be of interest. Much of the course will be devoted to working out basic examples of quantum field theories, especially those that have been of mathematical interest. Quantum field theory is not a subject which is at the point that it can be develo...
