Encrypted signatures and/or trusted timestamping could be used on whatever sort of digital format is used for your electronic paper.

:-D

That's very close to the electronic paper I described to some folks twenty years ago. (Not my original idea; I'd read the concept elsewhere and was just passing it on.)

Trivial to implement with today's technology. It's done every day in "3D Theaters" and relatively inexpensive home gaming solutions. (Special glasses must be worn, of course.)

For some reason, "gaming" and "entertainment" seems to be more important now-a-days than education....

Less obvious in 1966.

Don't diss gaming.

 Explore the social and societal aspects of gaming Explore the evolving world of social gaming and how gender issues are changing how games are developed. Learn about the gamification of society and how organizations are turning to social games for marketing and fund raising. Discover how the five dimensions of game addiction might relate to your experiences. Hear about the history and development of video games from one of the "rock stars" of the industry. As a Mensa Foundation-sponsored event, Colloquium annually provides Mensans and the public alike the opportunity to gather with industry experts and researchers to dig deeper into socially relevant topics. Past and current topics include the impact of the arts, gifted children, biosafety, consciousness, humor and climate change. Instead of focusing on the specifics of individual games or the latest releases at the July 2012 event, Colloquium 2012.2 will consider the bigger issues: what our societal obsession with electronic gaming says about us, how we got to this point and what the future could bring. We're confident the program will include topics — and renowned speakers — you've never seen collected into one forum in any other venue. You are cordially invited to be there when we delve into this multi-billion-dollar industry and find out why we play the games we play.

 2013-05-17, 17:48 #7 Stargate38     "Daniel Jackson" May 2011 14285714285714285714 739 Posts My dream device is made from the following: 1. An HD with MM127 bytes, yet it could fit into a human hand (maybe quantum-based). 2. A bug-free 65536-bit operating system (OS) based on Puppy Linux 3. A 1 Yottahertz 512-core CPU (preferably Intel) 4. An infinitely powerful RAM, capable of holding all the digits of Graham's Number. 5. An indestructable frame to house all the above, as well as the motherboard. I could hook up any compatible monitor to that. Last fiddled with by Stargate38 on 2013-05-17 at 17:49 Reason: Monitor info
 2013-05-17, 18:00 #8 Mini-Geek Account Deleted     "Tim Sorbera" Aug 2006 San Antonio, TX USA 2×3×23×31 Posts A smartphone-like device that can be resized/morphed at will. E.g. it could be stretched to the size of a large TV, a tablet, or a phone, and could be morphed to have multiple screens or a keyboard (with physical keys; no tactile-less surfaces, please) and mouse. It's also very lightweight, and has a battery that lasts for weeks between charges (and it charges automatically any time I'm near a power source, including the sun). To give it the feel of weight where helpful (e.g. prevent it from blowing away when it's a TV, or feeling too light as a mouse), it uses something to stay put when you want it to (suction? artificial gravity?). And it has the computing power of Stargate38's device, or the most power that the laws of physics support in a device like this. While I don't expect such technology any time soon, I don't think it violates any laws of physics. And it would be so awesome! Last fiddled with by Mini-Geek on 2013-05-17 at 18:02

I don't know the official term for the technology, but I call them blister keys, because they blister up from a flat surface. The technology is being worked on at the moment. No idea if it'll make it to retail. I believe the keys have to be installed at the factory, so you can't alter their location once they're placed, even though you can make them appear and disappear whenever you want.

I would like to have an alchemist's engine.

To be more precise, something which could rearrange the distributions of nucleons of substances placed within it. To abide within the laws of physics, energy might have to be added or removed from the device but, with careful design, two or more reactions could be chosen such that the exothermic reactions of one or more processes (3H -> 3He for instance) exactly balance the energy requirements of (an) other(s), such as 56Fe -> 197Au.

Producing gold from iron is rather futile from an industrial point of view, but being able to generate energy by fission/fusion to iron would be rather useful, as would be the production of copious quantities of free neutrons, positrons (by inverse beta decay of appropriately chosen nuclei) and isotopes which would otherwise be rather expensive to make in large quantities.
