Firstt he answer to the problem:
"An important mistake in Newton’s lunar computaÂ*tions, not hitherto detected, is the overestimation of the Moon’s mass by 100%. The Moon : Earth mass ratio is inferred to be 1 : 40 (Principia Book III Prop. 37, Cor. IV) when in fact it is 1 : 81; and the mean lunar density to be 1-5 times that of Earth (System of the World’, 56) whereas it is 0-6 that of Earth’s mean density." I was going to post more but fortunately realised there is little point when the answer is: What difference does it make? It is well worth the comparatively small (12 quid paperback on ebay) expense of looking it up and answer two is that nobody could manage to follow the book to its end as it was not written in any decipherable language except French. Here is the rest of it for what it is worth: http://dioi.org/kn/newtonmoonerror.htm To be honest I don't think the rest of you are any more up to it than Dawlish, so that shows how far askance he is. He at least is honest enough to admit it's gobledy gook to him. Not that I could help such a lost sheep if I wanted to. But now to something much more interesting. As the last significant pressure system for a week or more in the Southern Ocean runs out, it show us the meaning or impact of a cyclone's abstractive qualities: http://www.bom.gov.au/australia/char...Refresh+ View t+6 to t+84 Judging by the NA-EFS it is going to be a volcanic spell but the http://www..tropicalstormrisk.com/ showing at the time of writing is very strange. How is a Cat. three to change into a Cat. 1 in 24 hours? And more important: Wwhere is the seismic peak going to be? "One of the most underestimated surf forecasting variables considered by surfers is the "swell period". The quality of waves in a given location is largely dependent on the timing of sets coming in. The amount of time it takes for two successive wave crests to pass through a determined point is called swell period or wave interval. It measures the quality of the upcoming surf session. High quality waves are generated in open ocean, hundreds of miles offshore. Learning to interpret this information is easy. Short intervals, between 1 and 10 seconds means low quality surf. When surf report data tells of 20-second periods, increase perfect-peeling waves dramatically." Why this happens can be seen from a few feet above them so long as the observer and be surrounded by them. He should see that their angle of approach to the shore changes with each wave until the crescent is greatest after with the cycle begins again. A moments thought will tell him what must be happening. Oh dear I have not explained the behaviour of the cyclones. Never mind.... This is more fun. http://www.surfertoday.com/surfing/9...iod-in-surfing A bit dim but nothing wrong with simplicity: "How are waves made? Imagine a small pond, with no wind blowing on it, just pure calm glassy water. Now toss a pebble into the centre. Once the pebble makes contact with the water, notice that small ripples move out in all directions from the point of impact. The ripples continue travelling away from each other until they encounter land, where they break (if you look carefully) and dissipate. There are three things to consider from this example [actually there are four!] 1) The ripples have a measurable size or height, 2) They travel towards shore with a measurable speed, and 3) They cover measurable distance that spans from their point of origin until they reach the shore." http://www.stormsurf.com/page2/tutor...vebasics.shtml There are more than one soliton produced but he doesn't consider that nor if variety of mass / energy values make a difference to their number. Nor does he consider their return at impact although to be fare he is only dealing with generalities. "Regardless of the explanation, as groups of waves move from their source, the group becomes better defined, with waves of the exact same speed travelling together. If they have a period equal to or greater than 15 seconds, they can continue with little loss of size or energy, for thousands of miles.. Their wavelengths -the energy, is travelling deep under the surface, and there's little that can stop it." It can't possibly influence anything in its path without giving up some energy thus needing to have each point of impact restored to continue -they are following something. A wave with a 14 second period reaches down about 516 feet. A 17 second period wave: 761 ft, 20 second: 1053 ft and 25 seconds to 1646 ft. So you can see how little impact an opposing wind wave with a 7 sec period reaching down only 129 ft would have on one of these long period deep water swells." No you can't, you have to explain what is causing the other stuff which might be following something else in a totally different direction. So we move on: Only I can't be bothered. The storms are falling off so where is the next earthquake going to be? We would have to have considerably more empathy with waves to begin unravelling any of that. That is the trouble with the internet is that anyone can post anything and everyone is inclined to believe nothing. They may as well watch television. OK children; more later: When you understand this animated diagram, http://zonalandeducation.com/mmts/tr...tryRealms.html You will understand the sin(x) backwards, so a few say. I think it is that the sine of the cosine appears on the opposite side of the earth? (Which would explain tele-connections and the conundrum of the other wave trains and directions.) I've blown it now, so until I have slept on that, it is time for bed. |

I've blown it now, so until I have slept on that, it is time for bed. http://zonalandeducation.com/mstm/ph.../huygens3.html The thing is that Newton couldn't even have had much of an idea about this sort of thing: 2016/10/11 4.9 M. Fiji Islands Region 4.7 M. Java, Indonesia 2016/10/10 5.0 M. Tonga Islands But it is hard to believe that he wouldn't be disgusted at how far you lot have got by now. Run and hide under the rocks: http://www.metoffice.gov.uk/public/w...ime=1476576000 What do you suppose this was written for? For Dawlish to say he got it wrong? ‘This generation is a wicked generation; it seeks for a sign, and yet no sign will be given to it but the sign of Jonah. For just as Jonah became a sign to the Ninevites, so will the Son of Man be to this generation. The Queen of the South will rise up with the men of this generation at the judgment and condemn them, because she came from the ends of the earth to hear the wisdom of Solomon; and behold, something greater than Solomon is here. |
