  1. Back there, page 1, pics were posted but not of actual boobs. Though said pics were posted by boobs. (yours truly among them) Now it all seems like a distant mammary.

  2. You can get 300+ metres of Cat5E or Cat 6 cable for under £50. https://www.ebay.co.uk/itm/263661406588?hash=item3d6371c97c:g:0u8AAOSwRbtaTVBD&amdata=enc%3AAQAHAAAAoAyWySM%2FH%2FeJk0nCK%2BYKHCrzQSPzciD07Og%2BI1zAWi3myz34NXWws5w29bnKSktx2YrRVgC%2BTOg88WNqY9ytcbxNDM73mW3g4AgnVJb%2F%2BT2mKCoA7FOurT9bCGm4JZi6b8Br84eHsg6Vb%2F8gS%2F1AyztYSYVA3i1UPtWTWfNwf%2BVkDkfQeYtFo7gic754NSibCRZljifYeNfhHGoYOEigywY%3D|tkp%3ABk9SR-LOz_jEYQ But ethernet cable is only meant for 100m.max. Beyond this you would need an intermediate signal booster amp eg a router or switch as the cheapest option.

  3. Is these things tat i write right ? If there is a part in a planet that have bulged out too much or concaved in too much............ The gravity of the planet would pull in the bulged out part and fill in the concavity and add the volume of the bulgness to the radius of the planet equally and also the volume of the concavity would be equally reduced from the radius .....

  4. Good idea. PoE (Power over Ethernet) may also be applicable; one PoE & LAN signal repeater somewhere between house and caravan Personally I prefer a wall jack and a patch cable between wall & equipment.

  6. Why ? A small ball bearing will do more damage to a large billiard ball than another large billiard ball if one hits the other at speed. If the striking object is large enough it may simply knock the planet to a new orbit, more than damage it. Before someone jumps in, this is not to say there will not be any damage.

  7. Thanks, yes good value today as things have gone up, I expect I paid less than that but I only had a quick look around. The thing is that cable is outdoor grade as well. Cat5E is the original very fast ethernet standard. Cat6 is even better, but harder to work with. Cat = category. Can you put plugs on the cable ends yourself or get someone to do this ? Pre-terminated (plugs on) cables are available up to 350 metres, but they are expensive. Dim, You didn't answer my question about power, is your light going out ? ..which still needs an external power source i.e. a wire or powerbank, a solar powerbank, or a solar panel alone.. Not necessarily. There are spare pairs in the cable that can carry power from either or both ends. I wired up quite a few distribution networks in large buildings (hotels) like this. The term for this is cable powered router.

  8. I only mentioned 'non-charged' because it is easier to understand. A charged static BH would similarly have sperical event horizons, but it would have two; an inner and an outer

  9. Okay, so what would happen to say a waterworld planet tidally-locked to a red dwarf star. Could it be possible for a permanent iceberg to form on the dark side so large that it occupied a substantial proportion of the planets volume? If so, then gravity via buoyancy forces would seek to maintain a substantial elevation difference between the two hemispheres. As it happens, other issues might come into play such as ice changing phase to a higher density structure at depth could well be a limiting factor. But going back to Mars, the southern hemisphere is 2-3 km higher in elevation on average than the northern hemisphere for reasons no one seems entirely sure of. This would be consistent with the two hemispheres somehow having different average densities, though there are other possibilities.

  10. I have not gone through all the posts, so I am sorry if I am being repetitive. However, it seems to me that there still quite a bit of back and forth on the nature vs nurture thing. And I think the evidence we have in general on that matter is that it is almost always not a "vs" but an "and" situation. Biological systems in general are highly dynamic and responsive to external and internal inputs and often do not behave in a strictly deterministic way (which is why I dislike the way "nature" as a term is used in this context). Even the behaviour of very simple systems, like cells can be difficult to predict unless you control virtually every environmental input. And even then we see differences within a clonal cell population. Development, especially of the brain, is highly interactive and even cues during fetal development can affect the outcome. As such, for virtually any trait we have a certain proportion of genetic vs developmental/environmental component. However, figuring the exact distribution is extremely difficult. It also does not help that there is a lot of assumptions regarding gender or sex preferences which often introduce bias in studies. Dissecting cultural effects (or impact by the test system, like the clever Hans effect) can further muddy the waters. The reproducibility crisis in psychology, which at least in part is related to a big narrative with little data issue and the fact that sometimes the studies are poorly standardized. Either way, as with most biological systems we are clearly looking at a continuum of behaviour that has to be explored quantitatively. Trying to force a clear binary system out of it tends to be problematic and is likely going to boil down into semantic exercises.

  11. A sphere does maximise volume, concetrating the greatest amount of volume, and therefore mass, into the smallest radius/dimensions. Which is what gravity tends to do. And all static, non-charged, Black Holes are perfectly spherical. IOW, if something is big, and massive, enough, all other factors, like fluidity of material, don't matter;it will be spherical.

  12. You're right in that it's not just a matter of hinging together a bunch of qualitative concepts. I'm sure it depends on how much dissipation, gravity, tectonic energy at play... So the quantitative argument is lacking there. The case of Mars is interesting because of the relatively low gravity, as compared to Earth. That's probably why Mount Olimpus and Valles Marineris are so huge when considering them with some kind of scale law in mind. Even though Mars has strong dissipation in the atmosphere*. It doesn't have that much dissipation underground --if at all--, as it has no plate tectonics. So in my mind, lower gravity and tectonic dissipation could easily account for it. It's interesting to notice though that minuscule satellites, like Phobos and Deimos, look more like potatos. Very low gravity and practically no dissipative processes. Seems to bode well with the qualitative idea. There must be a scale law involved, no doubt. I'm being quite vague though, I'm aware of it. ------- * But having had active geology and erosion processes in the remote past. (EDIT)

  13. Interesting thoughts. If we take the Martian volcano Olympus Mons as an example: a 22 km high pyramid of basalt formed mainly around 3 billion years ago that is certainly taking its time to dissipate. If vulcanism were somehow to restart on Mars, might it not follow the old channels and lines of weakness and extend Olympus Mons even further from isostatic equilibrium? Gravity may always be there lurking in the background, but if changes to surface topography are dominated by 'random' events (asteroid impacts are another obvious example) the long term trend towards regularity may not be apparent. Elsewhere in the solar system I think the 396 km diameter Mimas is the smallest body with a gravity strong enough to deform itself. On the other hand, isn't a sphere the optimum shape of a given volume for collision avoidance? That may provide some statistic bias towards 'roundish' shapes for smaller bodies.

  14. No problem, although it's a bit complicated. I assume you mean ethnicity rather than ethics. My grandparents on the father's side ran away from pogroms in Belorussia and eventually settled in Baku. My father was born in Baku. My mother's family, including my mother, ran away from advancing German army in Ukraine, in the WWII. They too settled in Baku, after running around for some time. All the great-grandparents were Jewish, but starting with the grandparents, none were religious. My grandparents spoke Yiddish and Russian. My mother spoke Ukranian and Russian. My father, some Azeri and Russian. My first language was Russian, although I remember some words and phrases in Azeri. So, I'm not sure what is my ethnicity. Also, Baku, at least at that time, was a very cosmopolitan city. [Perhaps, the later part of this thread should be moved to The Lounge forum.]

  15. Good thinking. +1 In recent years, a cosmological theory to explain why the cosmos looks so flat --up to very large scales-- is being developed --Latham Boyle, Kieran Finn, Neil Turok, and others. The mechanism they propose is similar to what you're saying here. In fact, they use the Earth as an analogy. It's a combination of gravity and dissipative processes that does it. You need some fluidity, as Genady and Swansont said. So you need temperature, as J.C.Macswell pointed out. Because of plate tectonics, it would appear that bulges could potentially regenerate, thereby frustrating this process, and perhaps --from constant cooling of the Earth-- grinding the process to a halt. But dissipative mechanisms are constantly counteracting this tendency, with the result of flattening it out. Gravity does the final trick, depositing the ground pieces as close to the centre as it can.

  16. I remember learning about Sabir in school. Also, Sabir street in Baku. I have been to Shamakhy, Sabir's birthplace, but not because of that, but rather on a tour to Shamakhy Astrophysical Observatory - Wikipedia. Are you Azeri?

  18. I said: "And yes, an engine rejecting less waste heat than the prediction of the Carnot efficiency limit would violate a physical "law" of the universe." To which you responded: "Where is your experimental proof of this? That is a stupid response. The Second Law of thermodynamics is - so far as we can tell - a physical law of the universe and the Carnot limit results directly from it. Ergo an engine rejecting less heat that the Carnot limit would violate a law of the universe. It's not a matter of experiment. It's a matter of definition. Trouble is, you are not engaged in "scientific enquiry". If only you were. You have an idée fixe, which you have had for a decade now. You spend your time doing pisspot "experiments" in your garage in a hopelessly unscientific way, while determinedly refusing to learn basic science and instead scrabbling around for bizarre and inconsistent justifications for your refusal to accept the Second Law of Thermodynamics. You are tilting at windmills.

  19. That's even more far-fetched; that a baby is born knowing that pink is associated with girls, and blue with boys. Or do you think they gather this information during their formative years by associating colors with the gender of their parents or siblings ?

  20. I repeat swansont's comment from your previous thread. You seem to be mixing frames up. Who are the 'we' at the bginning of paragraph 2 ? You have specified a square train. What shape do you think it is in the 'stationary' frame ? Please clarify your description before you confuse everybody.

  21. I don't understand this. Children less than 2 years of age are basically a set of eyes. They see the world around them and make judgements about themselves in comparison. ( whatever they don't understand by looking at it, is picked up and chewed on ) The 'world' aroung them consists mostly of the parents ( and possibly siblings ). They are influencing the child's gender identity simply by being in the child's line of sight. It would be interesting to see studies done on baby boys ( possibly artificially inseminated ) into the mother of a lesbian couple. Would the baby boy have issues identifying as male without a 'reference' in his formative years ? ( if there is such a study, I'm sure haronY will reference it ) Clearly you've never worked with a bunch of women before. They can be rather ... 'catty'. ( no offense to cats 😄 )

  22. 20 years ago, I used to buy an RJ45 cable for £0.2 per meter and that was the regular price at a time.. It's doubtful that it has dropped.. 173 GBP/305m is 0.57 GBP per meter. You know what electronics and computer shops you have in UK. Check them. The cheapest option, which does not require a large investment if you have any old smartphone, is to buy a 2nd SIM card for it and enable tethering via USB.

  24. Is your goal to network your garden with your house (and have free intranet transmission) ? Or to have any internet in the garden regardless of whether it is from the house or not? A regular router can be configured for extended range mode, and put in the middle with some energy source. If one is not enough, a couple of them.. https://www.google.com/search?q=extended+range+modem+router (pay attention to whether router has built-in antenna (cheap router) or on screw -> external antenna (>50 USD) can significantly extend range of the router) (expensive routers can have multiple antennas/screws) You can buy a second LTE/5G SIM card for your phone.. (old phone connected by USB with desktop PC computer delivering Internet) It can also be plugged to a LTE/5G modem, which will be connected via USB to a computer and/or router. WiFi USB cards are cheap. 5-10 USD. 3G/4G/5G modem USB cards are for 35-60 USD. There are also PCI modems for desktops. Mutually exclusive expectations.. Too little data. Depends on your home WiFi speed. If you have less than 480 Mbps, modem with LTE SIM card plugged directly to PC might be the fastest option, as long as mobile operator will deliver enough.. I have problems with 15m range due to obstacles in the apartment.. and you want 260m - no mention of obstacles.. With what bandwidth? Counted in kbps? Mbps?

  25. Studiot used to do this alot for Exmoor residents (farms etc). Yes, you could run a telephone line down there but you would require external grade cable. So I have two possibilities to offer. Somewhere in the boxes of kit I still have one pair of narrow beam transmitter/receivers unopened in the boxes. The have a range of slightly over 1km. and were made especially for this sort of application. You are welcome to these for the cost of postage or collection if you ever visit Somerset. I had a quick butchers in the store but couldn't locate them yet. I do know they are there somewhere. Please note these are 'line of sight' only so if your cabin is hidden they won't work. Alternatively you must be running power down there, unless you have a generator. I had a good deal of success with 'through the mains' transmitters with a distributor device at the receiving end. Unfotunately these were always in short supply, so they seemed to go out as fast as I could get hold of them, so I have none left.

  27. It's not a "physical LAW" if a physical experiment demonstrates it can be violated. 1800's style "scientific" [sic] "LAW" [sic] proclamations are no longer considered a form of valid scientific inquiry. "You" me (Tom Booth) did not propose an experiment. Swansont proposed an experiment. I for one would like to hear exactly what he had in mind, but he was shut down. I suppose next you'll be calling him Sancho Ponza I guess that's appropriate Some dragon.
