Thanks Clem, that was what I expected. I agree entirely with the sceptical of views of American Physical Society (and Shyan on this website). using this link I also found more recent items: http://link.springer.com/article/10.1007/BF00671026#...

lol, thanks for 4, the long way of pointed out I had written bottom instead of down in the original post, I corrected that.

Yes Shyan, I understand that many numerical relationships have no physical significance. It is why I ask. If this has not been investigated, then I will take some time to look into the maths in more depth, but if it is known already, as I suspect it is, then somebody might have some pointers...

In a recent online lecture it was said there is now known releationship between the masses of quarks. My online search seemed to back this up. My comparison suggests: [SIZE="3"]Mcharm ≈ Mtop * fine Mup ≈ Mcharm * fine / 4 Mstrange ≈ Mbottom * fine * 3 Mdown ≈ Mstrange * fine * 7...

Thanks Both posts are a great help. The spherically symmetric stationary mass distribution assumption seems quite reasonable, I'm happy with the explanations of that. In atty referrence 1, Sean Carrol sites the proof that the Schwartzchild solution is the only solution, as Birkhoff's...

What if Schwatzchild has made the same mistake as Newton? ( 1 - 2MG / c2 r ) dt can be view as a binomial expansion to first order of 1 / ( 1 + 4MG / C2 r )1/2 dt then would the event horizon be at the singularity? I've been reviewing Susskind's online lecture series, and...

good that time :) - I use a depth 0.6 to get the 3.9 billion verse 0.5 to get 3.2

Yeah, 3.9 billion tonnes, but I don't really like that answer much. The picture on this page: http://en.mercopress.com/2012/08/10/volcanic-pumice-mass-size-of-belgium-floating-off-the-coast-of-new-zealand shows that the depth is far from uniform. Suppose 0.3 billion tonnes is closer to the...

Here is a link to one of the better articles I have found, but information is scetchy on google for sure. http://news.nationalpost.com/2012/08/10/volcanic-rock-mass-off-new-zealand/ I guess it it right to give some context to the question too. I know what happens when a oil slick hits a...

Can anyone answer a couple of questions about the new floating rock raft off New Zealand ? How much mass does it contain ? Where is it headed ? ( or will it disperse ? )

Nice paper H. Bergeron, he's good, really good. Presents the kind of analysis of the statistical that seemed appropriate for the original paper. He had to collect his data values from poor quality grafs, and still managed to demonstrate how the original 60ns result can be arrived at, as well as...

I have just completed a full listing of external links from this thread, using original authors and titles, available here [SIZE="4"]https://www.physicsforums.com/blog.php?b=3453 In the process I noticed that the following basic links have not been posted yet: Opera Useful Links...

I like this post, apart from the fact that it is a little over enthusiastic :smile: Nice to see a little original thinking. The summing of the PEW has bugged me for a while, mainly because I cannot see why it was necessary. Is there anything wrong with replacing...

Well I liked that Contaldi paper. He drew attention to the fact that testing the synchronization of two GPS clocks in an inertial frame via portable time transfer device has it’s own limitations. He does not state that the GPS system is wrong, or that PTT test was not valuable, but he points out...

Many thanks for that datasheet. Always nice not to have to find every paper, but you listed the Opera Master Clock chip, and in my post I was talking about the chip in the FPGA board. Soz, tried to make it as clear as I could. It is slide 38, T10 to Ts. If you also happen to know a link to...
