I know this stuff, I have a physics degree. In fact many years ago the NPL invited me along to a colloquium discussing how best to re-define the kilogram. (Because it is currently based on a lump of platinum-iridium, not on any "portable" physical constants. In fact the master kilogram and the sub-standards are all drifting in different directions, and that is causing some concern. I think the current plan is to use a perfect sphere of silicon, and then relate the kg back to the meter (which can be re-built from the wavelength of a particular light source). The NPL were looking at using a rotating Watt Balance at the time) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
