Nigel Hitchin(希钦)作为MichaelAtiyah(阿蒂亚)的学生,博士后和合作者,我不可避免地多次遇到Isadore Singer(辛格).自从他们于1955年在普林斯顿的研究所的首次见面,Atiyah和Singer就成为战后数学家群体的一员,这群人那时正在重新定义代数几何,拓扑,微分几何和分析之间的相互作用.1962年牛津大学的一次公休假开始了他们最引人注目的合作,其结果导致了Atiyah-Singer指标定理,对我而言,是其1977年的另一次访问导致了一个重要进展,而我有幸参与其中。 展开更多

Ferrum College and English Biomass Partners have been working together for nearly five years to design,build,and operate a biomass plant that will provide almost all of the thermal energy and a portion of electricity requirements for the campus.The biomass plant began full operation in 2014.This is the story of what they have learned.Introducing new technologies into existing systems to achieve strategic sustainability goals often create unexpected challenges that threaten hoped for benefits and leave participants wondering what went wrong.Yet even projects that present these challenges are also great sources of encouragement and learning.Many projects begin with a focus on the promise of a particular technology,(in this case using biomass for fuel),and while the prospects can be exciting,it can obscure the hard work of preparing the existing system for change.Moreover,the“systems”that frequently present the most difficulty are the human systems and behaviors that influence implementation.Because these are not well-understood or documented they are“uncovered”during implementation.The purpose of this article is to identify critical success factors and provide insight about processes that enhance the likelihood of success. 展开更多
