Dubbelosix Posted October 21, 2017 Posted October 21, 2017 (edited) May I ask you a question without sounded too .... well you know. What made you interested in talking about a complex subject like quantum gravity, when your roots are in chemistry? There is quite a difference between the two, and if you don't mind me saying, if you are a chemist, set an example so that you express your physics clearly. I wrote some work not long ago about a pre-big bang phase to the universe and actually involved a long study into chemistry. That might be a surprise, but we have to do it sometimes. I took chemistry at college along with biology, but sometimes, we need to go back to basics. The mind can only remember so much after a certain time.

Dubbelosix Posted October 21, 2017 Posted October 21, 2017 (edited) you can make errors all you want. I'll never hold you responsible for them unless you intend them. Many years before I am today, I was ridiculed badly for early idea's I had no capability to uphold with math. It actually... damaged me a bit, emotionally. But I realised, that I needed to prove those idea's so that I could in some way prove to people, I was not insane and actually capable of learning the math that the great prof. 's of yesteryear preached. I went to college. I became a drop-out in my third year. I realised I was suffering from bad mental health that was impeding my ability to continue with my studies, so I became a hermit for four years and studying in silence. I come here, I meet physicists elsewhere who have appreciated, I am not on the same score, but certainly on the same page (some of the time :p) and the result is... I am much happier I put this personal time into it because I learned much more than any college class threw at me. Edited October 21, 2017 by Dubbelosix

Dubbelosix Posted October 21, 2017 Posted October 21, 2017 So yes... put more time into your posts if: 1. Your theory doesn't match current physics, certainly check it over 2. Make sure your theory is consistent - in both the wording/terminology... but also if you ever come to math, make sure you understand its complexities, because I will not lie, mathematics is a very hard subject - take Einstein for an example, he actually failed his primary math tests. His relativity was so mathematically incomplete, he required his wife to help him finish it, who had no less, a PhD in mathematics. 3. Never lose hope even if you are proven wrong. This is the way of science. Also, make sure a theory can be falsified and fits observational or experimental data. These would be good principles to hold by when talking about the scientific methodology with physics. 2 minutes ago, Timo Moilanen said: I have (had) a career in pharmaceutical industry (every invention property of the company bla. bla)and last emlpoyer sacked me on more personal grounds (at least for my boss) promising me no job in Finland anymore and shut up or else (the else was not jive I'v bitterly learned) What comes to physics its not far from chemistry and I'we always been multidisciplinary What kind of career exactly?

Timo Moilanen Posted October 21, 2017 Author Posted October 21, 2017 In production from foreman as a student to plant manager and most job titles in between ( heavy ch. industry ) and consultant for factory planning ,instrumentation (you name it) . Most economically successful invention were in synthesis , that is the part of chemistry I,we studied only the basics (physical chemistry was my main in the chemical department) I had use for national economics when I briefly were into politics in late 90.s to early 2000
Dubbelosix Posted October 21, 2017 Posted October 21, 2017 (edited) I don't know, maybe it is just me, but I have no idea what you are talking about. I'll leave it for others to decide this, but will urge its not a reason for a banning. I am only saying this because people with (deficits) in the ability to talk the english language fluently may be interpreted wrongly. Edited October 21, 2017 by Dubbelosix

Dubbelosix Posted October 21, 2017 Posted October 21, 2017 (edited) But maybe the thread should be closed. Unless you prove me wrong, can you try and present your thoughts a bit more clearly? I mean, I am hardly Einstein myself, but I do have some knowledge in physics, and your claim to be a chemist, surprises me, since even chemists are usually trained in the scientific discipline. Trust me you can get there, but effort is needed. 5 minutes ago, Strange said: It is not a matter of protecting them from non-mainstream ideas (some non mainstream ideas go on to become mainstream, after all).

Calculated integrals and other to get k from Cavendish type of measurement and that way a value for Ti . The k factor goes to 1 very soon ( the geostationary satellite distance would give k about 1.0003) . All (long distance) formulas having G can be replace with Ti , but for example light bending "while passing the sun " is not simple as 1,75 arc s ,even thought Ti*M give the same as G*M. In universe GM =TiM but in lab. and other short distances it is TiMk Does the solar wind slow down satellites but not accelerate them back . Did the sun mass really shrink when the GEO something satellites measured earth gravitation in descending orbits . Was it UFO:s interacting wit the Voyager satellites slingshots . Did Eddington have lens problems or did just that star(s) have different light than others right besides. There are plenty of explanations and will be more.

studiot Posted October 22, 2017 Posted October 22, 2017 Gauss's Law refers to the integral of flux through a closed surface. The only directional effect is (for 3D) in or out.
Timo Moilanen Posted October 22, 2017 Author Posted October 22, 2017 The field is not alongside a surface and through an infinitely thin wall is 90 deg.at distance =0 and some symmetry (cylinder sphere and even flat surface give 90 deg "field lines ". I think gravity is a very stable and symmetric field with field lines square to "masspoint" on surface of body. (flux/field =90deg)
studiot Posted October 22, 2017 Posted October 22, 2017 (edited) You missed my point. The total flux through a closed surface is independent of the angle of incidence on that surface or how smooth or wrinkly that surface is. It is rather like that old theorem from Euclid that all parallelograms on the same base have the same area, no matter how skewed they are. Notice that the derivation refers to the total mass enclosed, the distribution of that mass is unimportant ouside the surface. Edited October 22, 2017 by studiot

Timo, look carefully where you are copy/pasting from or you will be attributing quotes to the wrong person as you have done here. I didn't say that and have not been discussing composition or Avogadro with you. I came back to this thread to add something to my last post but you got here before me, so please consider this as further explanation of the attachment in my last post. No doubt you will notice the derivation uses the Normal component. This is because the normal (and outward normal at that - are you aware there are two normals?) is the only part of the flux that can pass through the enclosing surface without being balanced out by a corresponding oppositely directed contribution from another part of the enclosed mass. In other words for every component at a point on the surface perpendicular to the normal there is an equal an opposite component somewhere else on that surface. Thank you for taking notice about my comment on chemistry, did you notice I had responded in that thread? Edited October 22, 2017 by studiot
