This is all about quantum dots ( which I think should be called quantum cells ) and it doesn't skip on details ( ) Pulisher's Blurb: "Wil McCarthy is a novelist, the science columnist for the SciFi channel, and the Chief Technology Officer for Galileo Shipyards, an aero-space research corporation. He has written articles for ... 'Wired'. He lives in Lakewood, Colorado." A rare instance of a patent issued for ideas developed while writing a book. Substance: The gadgets of sf are coming to a Wal-Mart near you, any day now. Describes the technology (current and projected) of "wellstones" and quantum dots, human-created pseudo-atoms on chips. Style: Serviceable journalese. Accessible to the non-specialist. Excerpts: p. 2 "...in his 1962 collection 'Profiles of the Future', writer and visionary Sir Arthur C. Clarke formalized three "laws" of technological development: First Law: "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong." Second Law: "The only way of discovering the limits of the possible is to venture a little way past them into the impossible." [i.e., drive trucks over the bridge until it breaks?] Third Law: "Any sufficiently advanced technology is indistinguishable from magic." [see Asprin's Corollary: "Any sufficiently advanced magic is indistinguishable from technology." in 'Mythtaken Identity' ] p. 11 "This is MIT, dude -- the 'present' was invented here thirty years ago." p. 77 "The three laws of thermodynamics, in their simplest form, are (1) you can't win, (2) you can't break even, and (3) you can't get out of the game." p. 173 "Is the human race collectively ready for point-and-click power over matter itself? Certainly, any abuses that are possible are also very likely to be attempted. Still, as with most other technologies, it seems unlikely that the potential evils of programmable matter outweigh the benefits." [Substitute for 'programmable matter' your choice of one or more of the following: nuclear power; DDT; combustion engine; fossil fuels; and even CO2. Seems a bit overly optimistic and even downright disingenuous for an sf writer of his generation. However, it attitude is typical of the Franklin First Person - Third Person Syndrome.] nessuna recensione | aggiungi una recensione
Programmable matter is probably not the next technological revolution, nor even perhaps the one after that. But it's coming, and when it does, it will change our lives as much as any invention ever has. Imagine being able to program matter itself-to change it, with the click of a cursor, from hard to soft, from paper to stone, from fluorescent to super-reflective to invisible. Supported by companies ranging from Levi Strauss to IBM and the Defense Department, solid-state physicists in laboratories at MIT, Harvard, Sun Microsystems, and elsewhere are currently creating arrays of microscopic devices called "quantum dots" that are capable of acting like programmable atoms. They can be configured electronically to replicate the properties of any known atom and then can be changed, as fast as an electrical signal can travel, to have the properties of a different atom. Soon it will be possible not only to engineer into solid matter such unnatural properties as variable magnetism, programmable flavors, or centuple bonds far stronger than diamond, but also to change these properties at will. Wil McCarthy visits the laboratories and talks with the researchers who are developing this extraordinary technology; describes how they are learning to control its electronic, optical, thermal, magnetic, and mechanical properties; and tells us where all this will lead. The possibilities are truly magical. Non sono state trovate descrizioni di biblioteche |
