(for now) delta^2 = 0 Oh, that's another wonderful story — of Clifford algebras: http://en.wikipedia.org/wiki/Dual_number , useful in automatic differentiation. As to your general point of what constitutes "internal representation", som

The answer isn't intuitive in any language other than the language of math Sorry for I might have not expressed myself clearly. "There is no number you can name between these numbers shown in this notation" is in English and appeals to in

Prove please ; ) It may be intuitive in English, just as 1/3 = 0.(3) thing is convincing, but you'll lose your infinit(el)y-hostile audience at a proof.

Not only, even what was intended merely proves equivalence of statements and not that either of them is true.

Well, in the seventies IBM mainframes had the Control Program (CP) and what is now the z/VM hypervisor, so yes precisely the same paradigm was dominant in architecting systems back then.

I don't think so, based on historical evidence. At least it doesn't seem to be like before- and after-45 or other midlife age. From all great theory builders, we rather see like this age being closer to late twenties. They start out by solv

I wonder why gay right activists ignore Turing's story for a long time. That is fortunate. I wouldn't like Turing to become another archetypal wicked scientist in tv shows puppetry inventory. Compulsive schizophrenic Nash seducing boys, a

I saw photos of Wozniak ostensibly (?) wearing heart-shaped glasses at the time, that left me with impression the logo could be intentional. I've read up on this just now and it seems that logo indeed had nothing to do with commemorating Tu

I think people thought for a long time on how to save the story, and not only the name, from being forgotten. Apple's original logo was designed as a such tribute.

This is a self-study book, the crux of it is that text is interweaved with hundreds of qualitative problems. I know of no other modern conceptual physics book I could recommend for interested 14 year old.

Talking of mathematics as a bondage-and-discipline precise science always seemed to me as misleading. This is not how mathematics is done , even if the result looks so. As to PG's definition of mathematics as study of terms that have a

No, he asked about protocol design. Ideally, a theory based on which engineers built something, but not the other way around, i.e. when something exists and some theorists are trying to build a de facto model of it. Edit: a theory that inv

Technically, though, there aren't any paradoxes here. The real reason why it is a paradox doesn't have much to do with notion of infinity per se, but with problem of infinite decision aka Supertask . Which reminds me of an article on

This is akin to entering room room full of engineers and shouting "I can fly! Prove I can't!", what do you mean, prove you can. Take any serious book on modeling bus and routing infrastructure (and not vocational guide on using protocols de

My favorite way, though, is just to make a grid of pairs of integers (numerator, denominator), and then count them by spiraling outward on the grid. This yields duplicates, but that's ok. Calkin and Wilf cleverly avoid duplications by arr

Peter Coles has been applying Bayesian statistics to cosmology for at least fifteen years. In the following blog note he explains how Bayesian probability really is only a tradeoff by using Doomsday Argument as a pedagogical exapmle. http:

Thank you Michael! How you and capable people manage to keep an eye on so many fields is a mystery for me.

Sorry for bugging, but how did you come around this gem? I thought I had a half of mathematical blogosphere on my radar already, yet no one seem to mention this, including Gowers himself. Or maybe you just happened to check Cambridge course

Examples of similarly interesting ideas: 1/ Aristotle's classification of forces and the idea of quintessence; 2/ Plato's idea that planets move necessarily in circles, because it's the most beautiful and simplest shape. That one witheld pr
