You might want to check out "Unix system programming with Standard ML" by Shipman. The first half of the book covers the basics of SML and the Posix & C interfaces, and also discusses building a simple TCP client and server. T

I just finished reading the book 'Gifts of the Crow' by Marzluff & Angell, which is a popularization of current research into Corvid intelligence, consisting of anecdotes, experiments, and neuroscience. Academics do, in fact,

Here's a good explanation (it reduces to F=ma, of course!). This explanation starts by answering a different question, then points out that energy is analogous. https://physics.stackexchange.com/questions/67432&#x2

Above the illustration in the text, the paper references work from 2001-2006 for motivating that geometry: [19] J. Khachan and S. Collis, Phys. Plasmas8, 1299 (2001). [20] J. Khachan, D. Moore, and S. Bosi, Phys. Plasmas10, 596

This collaboration between the three physicists and Tao actually started its life in a /r/math comment thread! One of the reddit commenters pointed the physicist (I don't know which of the three was asking the question) to a

I think that is precisely OP's point: on the long term, solar & friends are the only things that matter. If we get unlimited cheap power, we can only ever use it to generate an 'utterly miniscule' fraction of energy compa

Lol, that's a great story; if only that sort of thing was practical, how much more fun life would be :-) I actually had the opportunity to do something similar not too long ago. I'm a beginner learning to program and I had a littl

The right-click mouse gestures in Maya 3d are one example of solving this problem nicely. If you do it at normal speed, you see & select items on the context menus and submenus. But as you learn the gestures that form from making these

Dover editions are fine, imho. Certainly leagues better than the scans you are describing: https://store.doverpublications.com/048646119x.html If you want something nicer you could find a old used hardcover from the mid-tw

Hmm, I thought they had basically the same meaning! The premise of the book is to replace limits with the method of exhaustion, so I thought the title 'without limits' conveyed that clearer than the somewhat Punny title the book a

Tao's article certainly requires more background to read, but it gives a much deeper insight than explanations based on Cesaro or Euler/Ramanujan summation, which (as Tao points out in the article), in addition to being very puzzl

Oops, how could I misread 6 sheets per year as 6 sheets per day! o_0 Thanks for pointing out my error, this makes much more sense now.

I think you might be making the wrong comparison. We can conclude from your observation that their paper is expensive (relative to ours), or that our paper is dirt cheap! A laborer today might make $120/day so that's $1.60/

FYI the word 'complex' in mathematics is often used similar to it's usage as an English noun - "a whole made up of interrelated parts", e.g. a building complex, apartment complex, military-industrial complex. A &#x

The view that Dirac is putting forth, that the fundamental equations need to be simple, is certainly not the modern one endorsed by theorists today. Since the 70s or 80s, the point of view that has come to dominate is that our most accurate

One of the books given in the references is actually available in it's entirety [1] and appears to be quite good. Chapter 6 covers Seki, Chapter 7 is about his contemporaries and western influences (or lack there-of), and Chapter 8 is

I came across this in a talk by Sean Parent (once lead developer of Photoshop). What caught my attention was his assertion that they were able to reduce the GUI code of Photoshop by 600x, from a Million lines of code to less than 2k. It use

Adobe uses a declarative UI system, and what they call a 'property model', which apparently successfully reduced their UI code by a factor of over 500. The system is available here: https://stlab.adobe.com/group__a

Do you mean the example of 1 not being a prime, or the example in the article of Z[root -5] not having unique factorization? You could certainly discover the former, but not the latter as far as I can see. The idea is that the principle sho
