While concurrent program execution had been considered for years, the computer science of concurrency began with Edsger Dijkstra's seminal 1965 paper that introduced the mutual exclusion problem. (...) The first scientific examination of fault tolerance was Dijkstra's seminal 1974 paper on self-stabilization. (...) The ensuing decades have seen a huge growth of interest in concurrency-particularly in distributed systems. Looking back at the origins of the field, what stands out is the fundamental role played by Edsger Dijkstra, to whom this history is dedicated.

My interest in economics had the following roots. Like many of my generation I considered the heavy unemployment in the United Kingdom in the inter-war period as both stupid and wicked. Moreover, I knew the cure for this evil, because I had become a disciple of the monetary crank, Major C. H. Douglas, to whose works I had been introduced by a much loved but somewhat eccentric maiden aunt. But my shift to the serious study of economics gradually weakened my belief in Major Douglas's A+B theorem, which was replaced in my thought by the expression MV = PT.

I have seen the astrolabe called Zuraqi invented by Abu Sa'id Sijzi. I liked it very much and praised him a great deal, as it is based on the idea entertained by some to the effect that the motion we see is due to the Earth's movement and not to that of the sky. By my life, it is a problem difficult of solution and refutation. [...] For it is the same whether you take it that the Earth is in motion or the sky. For, in both cases, it does not affect the Astronomical Science. It is just for the physicist to see if it is possible to refute it.

A painter should never speak because words are not the means at his command. Words cannot express visually dimension at a glance they can only establish their own relationship in time.
However, it is possible for a painter, at certain moments of his development to formulate some of the problems he is facing in the growth of his work. A painting cannot be explained. Words can only stimulate the act of looking.
A visual problem is never put a priori as a mathematical problem but is born in the process of painting and evolves in a state of unawareness of the painter.

The essence of Hindu Dharma is not ‘tolerance' or ‘equal respect for all religious' but satya, truth. The problem with Christianity and Islam is superficially their intolerance and fanaticism. But this intolerance is a consequence of these religions' untruthfulness. If your belief system is based on delusions, you have to pre-empt rational enquiry into it and shield it from contact with more sustainable thought systems. The fundamental problem with monotheistic religions is not that they are intolerant but that they are untrue (Asatya or Anrita).

Much of the early engineering development of digital computers was done in universities. A few years ago, the view was commonly expressed that universities had played their part in computer design, and that the matter could now safely be left to industry. [...] Apart from the obvious functions of keeping in the public domain material that might otherwise be hidden, universities can make a special contribution by reason of their freedom from commercial considerations, including freedom from the need to follow the fashion.
