Thanks for the link inha. I just started reading it. So far it is quite nice. Nonetheless, I'd like to know what the experts on the subject of superconductivity think of the validity of some of the statements in this book. To quote the book, it says: "The main purpose of the book is...

ditto what selfAdjoint said

The examples you provided are not taken as contradictions because, according to the LCDM (Lamda-Cold Dark Matter) concordance model, the motion is not in any observer’s inertial frame, every observer will measure the speed of light locally to be 'c', and, unfortunately for NASA fans, none of the...

As someone who has used both Windows and Mac boxes, I would say that I prefer Windows. Not because there is some intrinsic greatess in the Operating software, but because the number of Windows users outweights Macs users. I find this fact means, for example, Windows users will be the first to...

Thanks, jtbell. 94-page PDF file!

Perhaps PF could implement a filter on certain phrases that would result in said post being automatically posted under a "Crackpot theories" section. This way we never have to see them unless we wanted to. These tagged phrases could include: "To quote Einstein, " "FTL signalling device" "If...

Zapper, I was under the impression that some models of string theory HAD made measurable predictions -- namely the deviation from inverse-square-law gravity at the sub-millimeter scale. Is this not generally accepted as a measurable prediction of ST? I think you already posted a link about...

Ooops! I never even considered looking at anything below the last post in the page. In that case webmaster, please feel free to ignore my above mentioned suggestion. Thanks Moon!

Sure it is physics -- everything is just physics when you break it down far enough :)

I've been coming across the term A-level courses in PF lately. Having lived in US and attended the US educational system (including college), I am embarassed to say I had never heard of this term before. After having wikipedia-ed it, I was still wondering if A-level courses exist only outside...

I'm sorry but physicforums really bothers me when I use internet explorer 6 to visit it because I get 2 Error messages asking if I want to download Flash 8 player (I always click NO) for every page that I click on. I do not have the lastest service pack from Microsoft because I have a slow...

The people most curious about physics, but don't know about it enough, will hang on to every word self-professed experts say because they are the next Galileo. Would it be all right if these people, and well as their crackpot teachers, were told to go visit PF so Zapper can set them straight...

I've been looking for a list of all the mesons there are, but cannot seem to find it online. Anyone know just how many mesons have been discovered? A link to a page that shows the names of each meson would also be appreciated.

I will admit to first being exposed to the term "room temperature superconductivity" during a pop-sci Michio Kaku interview. However, I was wondering, just what do the scientists who actually work in the field think of the possibility of room temp sc occurring in our lifetime? Also, do you...

The perihilion of Mercury and the eclipse of 1919 (Eddington expedition) are given as the first experimental verifications of General relativity. However, feeling pedantic, I was curious just which one these is accepted as the vital first prediction of GR in agreement with the real world? If...
