An order of magnitude Lubos in ur face.<BR/><BR/>Absolutely fascinating that one can end up so close from simple assumptions, a real tour de force (sic) compared with normal OOM. <BR/><BR/>Nanoscale machines: <BR/><BR/>Ich kann nichts so gut Deutsche sprechen, but IIRC in biological chemical machines the movement is more like 10 step forwards, 1 step back. (Not that graphical visualisation usually shows this. :-) And perhaps the Casimir force can be friend instead of foe? <BR/><BR/><A HREF="http://www.sciencedaily.com/releases/2007/08/070806091137.htm" REL="nofollow">""The Casimir force is the ultimate cause of friction in the nano-world, in particular in some microelectromechanical systems. ..."... The pair have worked out how to turn the normally 'sticky' quantum force of empty space from attraction to repulsion using a specially developed lens placed between two objects. "In order to reduce friction in the nanoworld, turning nature's stickiness into repulsion could be the ultimate remedy. Instead of sticking together, parts of micromachinery would levitate," said Professor Leonhardt.</A><BR/><BR/>Um, not likely, but if the reverse effect exists it would be cool anyway.Torbjörn Larssonhttps://www.blogger.com/profile/02022193326058378221noreply@blogger.comtag:blogger.com,1999:blog-8883034.post-30674930931811376872007-08-06T23:01:00.000+02:002007-08-06T23:01:00.000+02:00Have you seen websites that have a logo in the "be...Have you seen websites that have a logo in the "best viewed with mozilla/netscape" spirit saying "This page is best read with a grain of salt"?<BR/><BR/>This last comment at least was not best written with a grain of salt at least not with such a large one that fell off my prezel (got used to these as well es "Helles" beer since arriving in Munich) and ended up under the comma key of my laptop.Roberthttps://www.blogger.com/profile/06634377111195468947noreply@blogger.comtag:blogger.com,1999:blog-8883034.post-74516705771834017352007-08-06T22:57:00.000+02:002007-08-06T22:57:00.000+02:00Dunno.

Because it's a real 'first principles' calculation (taking as parameters only alpha, electron/proton mass ratio, ratio of electromagnetic/graviational force between protons etc? Because it somewhat fits into the whole landscape/anthropic principles discussion?
