[time-nuts] Another incermental improvement in atomic clocks

2011-05-09 Thread Francis Grosz
Timekeeping errors will be further reduced by better accounting for the effect of blackbody radiation on atomic clocks. See http://www.rdmag.com/News/2011/05/General-Science-Physics-Developing-An-Accurate-Means-For-Computing/?et_cid=1511177&et_rid=54735850&linkid=http%3a%2f%2fwww.rdmag.com%2fNews

[time-nuts] Distribution amp

2011-05-09 Thread Bob Bownes
I know it has come up in the past so I thought I would check here before hunting one down in the outside world. Anyone have a suitable distribution amplifier that they are looking to part with? My consumer device count has exceeded my source capability. :) Please respond offline, save a few elect

Overheard from a senior NASA research metrologist: "The only reason we're doing it is because we *can* (improving clock accuracy, said in the context of the aluminum clock). We can already time so accurately, just as an example, that if we launched a spacecraft today toward Sirius we could predic

Jim, keep in mind that that was not my statement but one made to a small group of people, including me, over at the Cape. The guy is a PhD (I know, I know, I am too, and what does it get me?) senior research scientist at NASA whose specialty is metrology. Now, you may be convinced that he is a co

I wasn't intending to cast aspersions... I was more giving an example of somewhere that atomic clocks need more work. And, I'm pleased that this group/list exists.. It's pointed me towards some useful stuff to solve some problems with the KaTS, and, as well, the archives are a great resourc
