Regulation of millitechnology

Suppose there were a class of technologies called millitech: science and engineering that could be measured in millimeters, from say about a tenth of a millimeter to 100 millimeters — in any dimension. That includes hairs, paper, pebbles, marbles, anything you can hold in the palm of your hand, anything less than 4 inches thick… Continue reading Regulation of millitechnology

Attitudes to nanotech regulation

An article this past weekend on Nanowerk reports on a study about attitudes toward regulation of nanotechnology among nanoscientists and the general public: As reported in the online version of the Journal of Nanoparticle Research today (June 19), Scheufele and Corley found that the public tends to focus on the benefits — rather than potential… Continue reading Attitudes to nanotech regulation

The Software of Civilization

This is essentially a follow-on to yesterday’s post about increasing intelligence (you might want to go back and read the comment by Michael A.). The main idea behind that essay was that intelligence consists of a varied lot of skills, which we’re building one at a time (or at least in separate efforts). When we… Continue reading The Software of Civilization

Smart Cascio article in Atlantic

Jamais Cascio has an article in the current Atlantic about how humans are getting smarter. This is the best article on the subject I’ve seen in the mainstream press, and better than most in the transhumanist corner of the web. Cascio’s main point is that, as we’ve always done, we build our technology to make… Continue reading Smart Cascio article in Atlantic

Nanodot upgrade

As you can see, we’re in the process of upgrading nanodot (and the main website will follow). Please bear with us while we work the kinks out.

More signs of mainstream interest in nanomachinery

This Physorg story gives the details, hat tip to Sander Olsen… Scientists from A*STAR’s Institute of Materials Research and Engineering (IMRE), led by Professor Christian Joachim, have scored a breakthrough in nanotechnology by becoming the first in the world to invent a molecular gear of the size of 1.2nm whose rotation can be deliberately controlled.… Continue reading More signs of mainstream interest in nanomachinery

A cautionary note, concluded

Last week I posted a story of strange behavior in the simulation of molecular machines. One commenter asked if this was due to something unusual in the starting configuration of the atoms. This was the first thing we investigated, and didn’t seem to be the case. There was a small amount to strain energy in… Continue reading A cautionary note, concluded

A cautionary note

One of the constraints laid down by DARPA at the recent Physical Intelligence proposers workshop was that the model of intelligence that was to be proposed had to have a physical implementation. It seemed odd to some of the attendees that this should be a hard constraint, since many models of intelligence have a perfectly… Continue reading A cautionary note

Physical Intelligence

About a month ago, the web was all agog over the announcement of DARPA’s Physical Intelligence program — Wired wrote: The idea behind Darpa’s latest venture, called “Physical Intelligence” (PI) is to prove, mathematically, that the human mind is nothing more than parts and energy. In other words, all brain activities — reasoning, emoting, processing… Continue reading Physical Intelligence

Buckytube-filled aluminum

Brian Wang over at Next Big Future has an article about improving the properties of aluminum as a structural material by filling with buckytubes, the way plastics are made stronger by filling by fiberglass. This isn’t particularly new: what’s new is that Bayer appears to be able to make nanotubes in enough quantity to make… Continue reading Buckytube-filled aluminum
