Automation and Early Computation, Social Inequaltiy

Haldane did not foresee the computer, the most potent agent of social change during the last fifty years. He expected his Daedalus, destroyer of gods and of men, to be a biologist. Instead, the Daedalus of this century turned out to be John von Neumann, the mathematician who consciously pushed mankind into the era of computers. Von Neumann knew well what he was doing. Soon after the end of the second world war, he started the Princeton computer project. Like Haldane's Daedalus, he had dreams ...

 A Logic Gate Made of People

“I don’t know your names,” Von Neumann said, tapping the shoulders of two of the soldiers. “The two of you will be responsible for signal input, so I’ll call you ‘Input 1’ and ‘Input 2.’” He pointed to the last soldier. “You will be responsible for signal output, so I’ll call you ‘Output.’” He shoved the soldiers to where he wanted them to stand. “Form a triangle. Like this. Output is the apex. Input 1 and Input 2 form the base.” “You could have just told ...

 Von Neuman and Predicting the Weather

I remember a talk that Von Neumann gave at Princeton around 1950, describing the glorious future which he then saw for his computers. Most of the people that he hired for his computer project in the early days were meteorologists. Meteorology was the big thing on his horizon. He said, as soon as we have good computers, we shall be able to divide the phenomena of meteorology cleanly into two categories, the stable and the unstable. The unstable phenomena are those which are upset by small dist...

 Life with Metabolism VS Replication

It is logically possible to postulate organisms composed of pure hardware, capable of metabolism but incapable of replication. It is possible to postulate organisms composed of pure software, capable of replication but incapable of metabolism. And if the functions of life are separated in this fashion, it is to be expected that the latter type of organism will become an obligatory parasite upon the former. This logical analysis of the functions of life helps to explain and to correct the bias...

 Fundamental Names in Computer Science

Consider some fundamental names: Turing (computation theory and programmable automata), von Neumann (computer architecture), Shannon (information theory), Knuth, Hoare, Dijkstra, and Wirth (programming theory and algorithmics), Feigenbaum and McCarthy (artificial intelligence), Codd (relational model of databases), Chen (entity-relationship model), Lamport (distributed systems), Zadeh (fuzzy logic), Meyer (object-oriented programming), Gamma (design patterns), Cerf (Internet), Berners-Lee (WW...
