Perhaps I am wrong about this but it is my understanding that we are not conscious of out autonomic actions unless we choose to be. And choice is one of the differences between consciousness and intelligence.

I think there are fundamental differences between autonomic/involuntary actions and deliberate actions made as a result of conscious thought (intelligence) Your genetic code can also be regarded as 'programming', its true. However as I understand this thread (hopefully intelligently 😄) it is all about intelligence, not autonomy. @exchemist I have added something to your thread on wifi

Yes my comments are meant in exactly that spirit. +1 Perhaps you know this, perhaps you don't; Engineering and other technical industries underwent a fundamental philosophical change in the second part of the 20th century. The emphasis moved from measuring the quantity concerned to measuring the error in that measurement so that it might be controlled. This is the point I am making. We see this is large ways and small ways as the various disciplines embedded errror resistant techniques into everyday practice. Checksums became standard. In surveying Did your triangle angles add up to 180 ? Did you read the angles on both faces? Did the sum of your foresights minus the sum of backsights equal the final level difference ? In structural and other engineering the limit state method of design was introduced. In information technology and coding science checksums were introduced. In concrete technology statistical control of materials was introduced into the mix design. In mecfhanical and electrical engineering redundant circuits and pathways were introduced into machine and equipment design and even whole network systems. Backup pilots, backup sytems, backup data storage backup backup and backup again. The concrete mix design is a good example of living with and controlling small errors as is limit state design. The surveying examples are good examples of minimising large errors.

You are correct I didn't spot that. +1 But this makes it worse than ever. If I read this correctly the AI has deliberately excluded certain errors despite being asked (I hope you did) about all errors. Blunders are errors and and often have the largest consequences such as getting on the wrong train or plane and ending up in Cape Town instead of Cairo. So what to do about them is especially important. The UK NHS for instance has a schedule reporting of medical errors including 'never' incidents which should never happen such as amputatiing the wrong leg or worse the leg of the wrong patient. Before retirement, my wife used to teach drug calculations. At the end of her courses students took an exam she prepared. She required a 100% correct pass mark and had a running battle with the managers who wanted to let staff loose on the wards with a lower one. At each such meeting she offered the exam (10 questions) as said "Here are the questions which of these would you accept your student to get wrong ?" she further pointed out that "Each of these questeions were based on real errors that had occurred and lead to the death or serious injury to the patient"

Gosh was that iNow or AiNow speaking ? 😄 I note the examples offered by technical members seem to be about 'business' not technicalities. In my experience accountants were the first to get decent calculators, then the first to get decent computers. Going back to technicality has anyone else experience of AutoCad and early Windows ?

Unfortunately your AI starts with a blunder, the same blunder that I am frequently warning new posters about here. The all embracing, blanket statement that can so eaaily be contradicted. Like many humans I understand the idea behind this statement, but it is just incorrect, though too many humans make similar ones. This demonstrates that the AI does not understand the words. A much better way to put the idea is to say that when we make a measurement, out measurement may actually be the correct result but we can not be certain of this. The trick or best we can do is to try to ensure that our measurement is the most probable result and further that the uncertainty, measured as an probability, is a quantifiable and acceptably low value.

And what does the fount of mystic wisdom say about blunders ? I note it has not mentioned them. Personally I would classify swansont's blueberry example as a blunder.

One possibility, depending upon your budget though you can get these s/h from _bay, is the explore the Sonos systems. https://www.sonos.com/en-us/guides/amp They have several useful products depending upon where your router etc is.

All failures are significant from something that is supposed to be ultra reliable if not actually infallible. It would be interesting if you would do some tests to find out what your AI knows about the theory of errors and what to do about them.

Rather you don't understand where I am coming from. There is a grain of truth in what you are describing, and I respect that, but my experience has been of a far wider set of scenarios.

No indeed. The second site I worked on (for the contractor) we had to supply the client with a calculator that had a square root button. The first site no one had a calculator. I did all the lab testing and results by hand. Since then I dont't think I have ever met an IT person who asks "What do you want or What do you need ?" I have generally come across many who say "This is what you must have" This latter attitude hardened as hardware gradually gave way to software.

Unlike you younger folks who so readily accept the latest bees knees in It long before it is needed and certainly well before any beta testing, I have seen so many 'new improved' washing powders ( sorry IT upgrades) come and go that it is boring to try to keep up. It is a great effort on my part to get something as I want it and annoying to find it changed by upgrades almost every time I log in. Once upon a time filled in lots of details here, but now I don't even know how to access these things, if it is still possible.

Depends how much time you had to devote to the subject. The admins here have several sites to attend to and, sad to say, SF is a minnow compared to some. So it falls to all of us members to try to make it attractive enough to be able to keep going, if we want the that.

Of course I forgot about bluetooth as I don't actually use it. This has a 10m range https://www.farnell.com/datasheets/2793383.pdf Bluetooth 2-in-1 Audio Transmitter & Receiver - BTTR2

My lounge amp is a Kenwood KA550 from that era, probably very similar. So from the spec sheet you have two tape outputs, one to DIN and one to RCAphono at 350millivolts RMS. A S/H Rotel RX403 is currently fetching around £139 on the net. It's lunch time now so I will look for suitable transponders this afternoon. I note there are a couple of new posts on the old thread that appeared after the move. Thank you swansont. Connections Number of inputs: Phono MM: 2 mV, 50 kOhm. Aux: 150 mV, 50 kOhm, max. 15 V Tape Play: 150 mV, 50 kOhm, max. 15 V Antenna FM (75/300 Ohm), MW (300 Ohm). Number of outputs: Tape Rec: 350 mV, 3.3 kOhm. Tape Rec DIN: 120 mV, 90 kOhm Headphones: 2 pairs of speakers

Well I don't know, as usual our politicians have f___ed up in their legal drafting. I find some measure of information useful as I try to pitch my responses to the correct level for the poster concerned. You may have seen me ask general innocuous quests for this purpose. Personally I distinguish with legitimate organisations I choose to deal with and those two rags who seem to thing I have nothing better to do than answer the phone calls. But the thing that really get my goat are those who ring up and then demand that I prove my identity, but get really irate if I say "Well you rang me, what proof of who you are can you offer ?"

What's wrong with your other thread ? Reported

The standard tape output will be about 100mv rms, the old audio inter equipment standard. I presume you amp is too old to have a digital audio output, either coax (RCA or Phono) or Optical. I use the optical (Toslink) with my telly. What is the make and model of the amp please? Note I have asked the mods to hive this off as its own thread as it is of more general and long term interest.

Like the way you have summed it up. +1 However there is still more than one way to skin a cat. I don't know anything about echemist's kitchen or the availability of UK mains sockets or where he wishes to place the speakers. So here are a few thoughts. Modern mains sockets often incorporate a USB outlet with sufficient power to power an ordinary speaker. Plugin usb adaptors with a 13A passthrough are also available if there is a shortage of three pin outlets. It may be cheaper to get remote usb speakers than comvert the Dentons. There are some pretty good ones available nowadays. There are also modular boxes available that could power the Dentons if you are set on keeping these. But modern solutions will take up less space. It may not be necessary or convenient to convert the audio signal to wifi. It is desireable to digitise it (though I would use a signal level not power level output eg the tape at the amplifier - I do this for the TV at home). The digitised signal may also be transmittable through the house mains. I have done this on lots of occasions. If wifi is necessary, this can be done using a cheap converter box designed to send a signal to wifiheadphones. Last year I set up one of these to send a signal from my daughter's electric piano to her wifiheadphones. @exchemist If you are interested in any of these ideas, I will see what details I can dig out.

My apologies I omitted the name of the last author it is Prof Michael Benton. One other thought. It is useful and common these days in paleobiology to link the timeline to other physical geological events (the sort I am more interested in), especially in the light of plate techtonics and 'continental drift'. Going by actual years ago, rather than geological ages, is better because they occurred at somewhat differnt times in different parts of the globe, and also they have somewhat differnt names in different parts of the globe, names that are still being chnged. So here are few more sources. The Winters of the World Brian John (editor) David and Charles A timeline of ice ages Eruptions that shook the World Oppenheimer Cambridge University Press Obviously a history of vulcanism. The Emerald Planet Beerling Oxford University Press A history of the atmousphere Origins Ron Redfern Cassell and Co The Evolution of the Continents, Oceans and Life.

Hello and welcome, nice to see a real science project. My interest has always been more physical geology than palaentology so the few books I have on that side of things tend to have hand drawn sketches. Nevertheless here are some thoughts. First Adrian Lister has an excellent book published by the Natural History Museum who hold Darwin's fossil collection. It is a cheap full colour book well worth looking at to see how they did it. The Nat Hist Mus itself is also well worht the visit. A few years ago I obtained this book from Cambridge University Press which gives calibration data for timelines. It's quite a thick A4 book that goes into minute detail. The science book of the year 2024 is interesting and gives the most up to date taxonomy, though the few diagrams are poor. A better book in some ways by the professor of Palaentology at Bristol is When Life Nearly Died This has quite a few useful dated timelines of the sort you describe.

Once again I never said anything about those possible effects you mention. Anyway how about walking me through the mathematics of Cavendish experiment set against your continuous background of that enormous density ? You say forces are transmitted. So what does the force vector diagram look like ?

Solid has a specific meaning in physics, chemistry materials science. How are you using it here ? What is its temperature ?

What don't I get ? Why the addition of lots of weasel words and mangling of Phyiscs to state something - I don't know what something.
