I was leaving that as an exercise for the reader

You have posted 100s of messages on gravitational waves - have you even read the Wikipedia page? Gravitational waves are not Newtonian and are not force and as such they do not vary as the force varies; we talk about the amplitude (in terms of a strain) and the polarisation (in terms of + and x) of gravitational waves not the force. I get you cannot do the maths - it is very hard - but can you not read the Wikipedia page and do a bit of googling?

Will check out the document - thanks. And re Rossi - huge numbers of people do; for the benefit of this thread and others I try to keep an open mind and judge only on the claims made (which per my last post above they fail badly even at maths) . This attitude also helps stop disciples from dismissing all my posts as preconceived dogma - and I would love one of these claims for cheap clean energy to be true

How many posts on gravitational waves? Newtonian gravity is instantaneous and there is no gravitational radiation within it - you need GR and the speed limit on gravitational propagation to get waves

I had often wondered how they worked out pronunciation of such ancient languages - I assumed some of it was from rhymes but that does not help in many circumstances. I had not thought of the mistakes - brilliant.

Not sure that getting a payload to around 1-2 AU from earth - and then doing it for 3 or 4 others is ever the economic option

This ^ search iPlayer for Science Now and get the following page Kinda says it all really

Perfect - good spot.

I would go along with Swansont's use of 'town' - I believe this was also the Koine and if you have any more elderly friends in Greece you can ask if it was the Katharevousa; however I think it unlikely that something as basic as this had two varying pronunciations before the wholesale adption of Demotiki so maybe it was Taf in Katharevousa too.

My teachers always said that I tended to forsake the obvious. Welcome to Geek Central. You will get confirmation you are in the company of nerds when you note that Tau day is celebrated to an equal extent

Yeah - I remember before the series of matches between Deep Blue and Kasparov (I think I have those names right) that a commentator claimed that it was unlikely to see a Chess grand-master of Kasparov's talent being beaten moreover that a Go grand-master would not be beaten within any of our lifetimes

If they gained or lost a measureable/noticeable amount of time and as we already know that orientation and position matter for gravitational wave detection then we could construct a really neat and easy gravitational wave detector by setting up a small array of atomic clocks at different angles and inclinations. As they actually built vast underground interferometers I am guessing that the aforementioned atomic clock detector wouldn't work at today's accuracy - if at all. And if you are lucky you might soon receive a pretty amazingly accurate answer about the atomic clocks in Washington USNO

! Moderator Note Can we stop commenting about DanMP's motivation or characteristics please? No matter how outwardly unlikely a proposal is it deserves to be argued on its merits and not on perceptions about the poster. We attack ideas never the person. Do not respond to this moderation within the thread.

We are consistent ( I would say "today is the 15th of March 2016" and I would write that as 15/3/16) and we are more accurate in that we have the most rapidly changing and most significant digit as the first and most obvious. I regularly need to look at my watch/computer/phone to check which day it is (too many years of substance abuse - I know) but I never have to check which month it is - you put the most useful info at the front. edit I cannot believe we are still arguing about this - and that the US standard will probably dominate in the end. Just curious is there anything we would not argue? Efimov day is not one I have heard mention of

And for the Brits. But we have to make do with American counting - that is unless you have plans to put 31 days in April or get a calendar with 14 months

Do we see gravitational lensing of neutrinos? The answer at moment is no - but only because we are so rubbish at detecting neutrinos You would need a super nova behind (or close to behind) the sun or a nearby galaxy. But we can sometimes detect Supernovae behind things because the rays of light that (if they travelled in a straight line) should miss the earth are bent back by gravity and we can detect them (overly simplistic explanation but good enough). If Neutrinos from this Supernova are not affected by gravity then we should measure a single burst of neutrinos at the time needed to travel straight line distance (not light path geodesic) from Nova to earth. No need to worry about the fact that there is a galaxy in the way - the neutrinos will go through as if it wasn't there. If Neutrinos from the Supernova are affected by gravity then we should see a spread over time of neutrinos - from those that travelled direct, those that have been mildly bent, though to those which have been gravitationally lensed the most and followed the trajectory outside the lensing galaxy on the same path as the light.

Sorry - I have just realised that this is the thread I have moderated in; I thought that was the other one. I can participate or moderate - not both; I should step away from this thread. Apologies

From a paper you claim to have read and has been discussed above. The waves are not isotropic in that their polarisation changes. Others can confirm / deny my gut instinct heuristic ; if the waves were completely isotropic I fail to see how any Angular momentum could leave the two body system - and all reports I read state that the angular momentum decreases Sorry - I have just realised that this is the thread I have moderated in; I thought that was the other one. Apologies

Me too. I think it may also cheer my father up for many weeks to come - he is 90 and loves a natter

! Moderator Note Robbitybob Please take this warning seriously - you have to start reading and understanding responses before replying. It is most disheartening to see questions answered in one of your threads only to be asked again in others of your threads, or the exact opposite of the correct answer being affirmed as a follow-up; what makes it worse is when your subsequent posting makes it clear you do not even understand the basic physics and terminology of the discourse. You are probably posting more than any other member at the moment and unfortunately the quality of your posts is declining with the volume. Take time to read and digest posts - and if you do not understand them then perhaps a bit of reading around the subject is the way forward rather than your present parallel attack of asserting your arguments and asking very basic remedial questions. Do not respond to this moderation within the thread - you can report this post if you feel it is unfair.

Happy pi day - good year too 3 14 16 And Happy Birthday Albert

"force...was...joules" - really?
