Mars is just dumb mass at the bottom of a gravity well; there isn't even a biosphere there. They should be working on uploading and solving the nanoassembly conformational problem instead. Then we could turn all the available dumb matter into computronium and use it for processing our thoughts. Long-term, it's the…
What I really, truly miss is the physical trail that typing usually gives you. Typing on an actual typewriter on paper is only a softer version of chiseling words into stone.
When I am reading Hamlet I often develop an urge to tell people about it, as if the Melancholy Dane's history had heretofore been classified as a top secret. I am bursting with information about Hamlet, so filled am I by the massive "evidence" presented by Shakespeare. So I sit down at my writing table and begin to…
In most mammals, the mother’s blood supply remains safely isolated from the foetus. It passes its nutrients to the foetus through a filter, which the mother controls. The mother is a despot: she provides only what she chooses, which makes her largely invulnerable to paternal manipulation during pregnancy. In primates…
A new study appearing Aug. 1 in the journal Current Anthropology finds that human skulls changed in ways that indicate a lowering of testosterone levels at around the same time that culture was blossoming. “The modern human behaviors of technological innovation, making art and rapid cultural exchange probably came at…
Many different competing theories of happiness have emerged from the field of positive psychology, but if there’s one thing virtually all positive psychologists agree on, it’s this: there are many ways to be happy, but we cannot find happiness. No object, no event, no outcome or life circumstance can deliver real…
In our real lives, hard work is too often something we do because we have to do it—to make a living, to get ahead, to meet someone else’s expectations, or simply because someone else gave us a job to do. We resent that kind of work. It stresses us out. It takes time away from our friends and family. It comes with too…
‘Uncertainty’ is a complex and multifaceted property, sometimes originating in a lack of information, and at other times from quite fundamental disagreements about what is known or even knowable (Moss and Schneider, 2000). Furthermore, scientists often disagree about the best or most appropriate way to characterize…
The pattern will break down once you get past 8192, which is 2^13. That means that the pattern continues for an impressive 52 significant figures (well, it actually breaks down on the 52nd digit, which will be a 3 instead of a 2). The reason it works is that 9998 = 10^4 - 2. You can expand as 1 / (10^n - 2) = 1/10^n *…
The distinctive characteristic of the Analytical Engine, and that which has rendered it possible to endow mechanism with such extensive faculties as bid fair to make this engine the executive right-hand of abstract algebra, is the introduction into it of the principle which Jacquard devised for regulating, by means of…
. . in real life mistakes are likely to be irrevocable. Computer simulation, however, makes it economically practical to make mistakes on purpose. If you are astute, therefore, you can leam much more than they cost. Further¬ more, if you are at all discreet, no one but you need ever know you made a mistake.
The difference between a piece of stone and an atom is that an atom is highly organised, whereas the stone is not. The atom is a pattern, and the molecule is a pattern, and the crystal is a pattem; but the stone, although it is made up of these pattems, is just a mere confusion. It's only when life appears that you…
It [the Scientific Revolution] outshines everything since the rise of Christianity and reduces the Renaissance and the Reformation to the rank of mere episodes, mere intemal displacements, within the system of medieval Christendom .... It looms so large as the real origin of the modem world and of the modem mentality…
If a man wants to succeed in his work, that is, to achieve the anticipated results, he must bring his ideas into correspondence with the laws of the objective external world; if they do not correspond, he will fail in his practice. After he fails, he draws his lessons, corrects his ideas to make them correspond to the…
Again, to be a hacker, you have to enter the hacker mindset. There are some things you can do when you're not at a computer that seem to help. They're not substitutes for hacking (nothing is) but many hackers do them, and feel that they connect in some basic way with the essence of hacking. Learn to write your native…
Alan Turing, the father of the modern computer, began by thinking about the highly conscious and deliberate step-by-step calculations performed by human “computers” like the women decoding German ciphers at Bletchley Park. His first great insight was that the same processes could be instantiated in an entirely…
We must take our sensory experiences seriously but not literally. This is one place where the concept of a sensory desktop is helpful. We take the icons on a graphical desktop seriously; we won’t, for instance, carelessly drag an icon to the trash, for fear of losing a valuable file. But we don’t take the colors…
Almost all of those limits start with a peculiar fact about human memory: Although we are pretty good at storing information in our brains, we are pretty poor at retrieving it. We can recognize photos from our high school yearbooks decades later, yet find it impossible to remember what we had for breakfast yesterday…
In the physical world, the only way to learn tomorrow’s weather in detail is to wait twenty-four hours and see, even if nothing is random at all. The universe is computing tomorrow’s weather as rapidly and as efficiently as possible; any smaller model is inaccurate, and the smallest error is amplified into large…
We are survival machines, but 'we' does not mean just people. It embraces all animals, plants, bacteria, and viruses. The total number of survival machines on earth is very difficult to count and even the total number of species is unknown. Taking just insects alone, the number of living species has been estimated at…
