    Permanent? dont have that busbar flapping arund in the breeze, clip it down. Does that loopy bit have a purpose?

    You just need more practice. Reheat some of those, let the iron linger, add more solder maybe flux too. until the solder flows and goes shiny.

    The iron needs to dwell long enough to get both parts up to temperature so that the solder flows between both. This means that when heating a larger thermal mass, like the big wires, you need to dwell longer.

    You’re heating the parts to be joined, not the solder. Add more flux.

    Practice on different sized wires or parts attqached to large ground planes and so on til you get a feel for the thermal mass of the joints.

    bigclivedotcom on youtube has some videos on soldering basics. https://www.youtube.com/watch?v=aIab66EgfHM










  • Have you been watching a fairly terrible late1990/early2000s tv series starring jessica alba? I’m pretty sure they had some fish-mutants.

    I don’t think you can radically change a human’s environment that much faster than nature, especially not a system so critical as breathing. The whole organism (including the internal microbiome) needs to co-evolve with itself and the ecosystem it is to survive in - to function effectively as an independent organism. I don’t know how long it took cetaceans to evolve, but even they still breathe air at the surface - they’re really just big flappy hippos.

    I’m sure it’s not impossible but I think you’d need, many, maybe thousands of generations for it to become something viable that can effectively provide enough oxygen to the other systems - or more likely adapt all the other systems to less oxygen. So it might have to live basically in a lab / sea-world for centuries. You might need scientists with unusual ethical standards to get to human - but an underwater rat? I’m sure you’d find a few Dr Mephestos out there eager to drown a few thousand of those.

  • Haven’t you identified this casino as an element of the universe, and observed how it works? I can’t predict exactly where the ball will fall, but i don’t think roulette is supernatural. I can understand the non-deterministic process and chacterise the probability density. And test and observe over many trials to confirm the stochastic model is right.

    Uncertainty, randomness, even entaglement and action at a distance can be observed right? with some degree of preision? When you start to pin them down with experiments and describe the probability distribution experimentally, repeatedly, testably then hey presto; I’d call that a “natural” obsrervable random or non-deterministic process.

    Maybe it’s natural with some more uncertainty than usual , but as you said about Heisenberg everything is at least a bit uncertain, so it’s really just a matter of how big is the variance of the probability distribution of your explanation or prediction.

    I know you’re just trolling by trying to use “supernatural” as a term for, unknown / uncertain / not fully explained / non deterministic. For me supernatural might be be predicting that the roulete wheel will come up 6 black next time. A way to determine the exact oucome of a process we believe to be non-deterministic.

    Of course that supernatural thing (like magnetism was back in the day) will become mundane if and when science can pin it down experimentally. Develop a model with a lower variance estimator.

    I’d argue entanglement has beein going through a process from supernatural and spooky when it was only theoretical. To natural now that it’s been proven, but theres still a lot of uncertainty. so you might call it peri-natural?

    I see the whole process of scientific explanation being moving our understanding of phenomena out of the mystical magical and supernatural realm, into the mundane natural world once we understand more about them and have some well understood (even if weak and incomplete) predictive power.


  • The “god” part becomes an unnecessarily complex explanation. I prefer simpler explanations when they fit the data just as well as the complex ones. It also reduces te risk when trying to broaden out to other lines of enquiry.

    As johsny said It makes the god explanation redundant for the large topic of species of life. There’s no need to waste time or energy “disproving” god. The whole concept of god is simply useless to understanding - and so is a waste of time or mental energy.

    But the so called explanations referncing god are typically such bullshit anyway nothing testable, no evidence, just “god did some shit”, “isn’t god cool/powerful”. So they never were actually useful to scientific reasoning. However much they may pretend otherwise religions are so much more aligned with laws and social structures and norms of behaviour than they are about advancing science.



  • Perpetual motion machines are one of the mothers of all snake oil. Maybe AI can turn base metals into gold too. Do these AIs even really have a demonstrable understanding of thermodynamics yet? It needs to prove itself with a usable output for a clear observabe application on a small scale scale before anyone should start chucking vast amounts of energy at it in hope of what it can “maybe” do. I’d much rather chuck all that energy into trials of tokamaks or something like that.
