      I’m not from an English-speaking country and I still use this every time I pick up a screwdriver.

      For know which is left and right I switch to my own language to say ā€œright says Hi, left says Byeā€ with a mental or physical mime of shaking someone hand and then waving goodbye with the other. It originally has alliteration, but kinda works translated as well.

    Electricity. I’m a field electrician studying the engineering side.

    Electricity is all about guiding voltage and current in a preferred direction as to do some form of work, whether it’s producing light, turning a motor, or integrating into logic circuits to make your computer do tricks.

    To keep yourself in the clear, don’t touch the shiny bits.

    I have a PhD in mathematics (set theory). It would be pretty tough to explain to a child. Specifically my PhD is in determinacy, which is way easier to explain than most branches of set theory, but you do need a decent understanding of infinity to really get anywhere.

        Wastewater - Separating liquids, solids, and gases for responsible re-use.

        Botany - Learning about the natural world and how it relates to everything you know and love (i.e. without plants there would be no humans, chocolate is yummy, grasses feed the world, etc).

    Photography and mechanical keyboards, and cooking. I am no Ansel Adams, and I don’t know every new photography technology and setting, but in terms of the fundamentals and the core principles, I can definitely teach a class, and have taught people, although not children. I haven’t taught the other two, but I could definitely expand on them for, well, hours for mechanical keyboards, and days to weeks for cooking. I’m almost certainly forgetting several topics too, but whatever, this is Lemmy.

    EDIT: If anyone is rolling up in here teaching classes on residential plumbing, electrical, demolition, or contracting, hit me up. I need to my house down to the sticks, and redo all the electrical and plumbing and the floors and the walls and the insulation. I’m trying to figure out how much of this I feel like tackling myself, or is even possible of tackling myself, versus how much I am willing to pay professionals to just take care of for me. Oh, also I designed a sweet fence for an area of my backyard to keep my pets safe, so would love tips on building that too. Cheers!

    ā€œSmart Cityā€ is a concept of a modern city, where a bunch of different things like pollution or traffic density can be put into data, collected and evaluated, so that we can have quick access to the status of a whole city.

    Things to use this for: avoiding bad traffic, planning new city projects like bridges or even looking where you can save money on a city budget.

    Currently there’s quite a few cities and projects who act as case studies but this is all preparation, we still need lots of science until we can make use of the full potential of this idea.

    Emotion regulation? Attachment styles and the consequences of insecure attachment and childhood trauma? Epistemology and the illusion of certainty? Why Kierkegaard>Nietzsche (but you need to read both!)? Idk, depends on the kid and how much time we’d have, I guess. šŸ˜…

    In earnest though, if there’s one topic I think I have some data on that most will never have is on the two fundamental ā€˜arguments’ for not believing in God (one very flawed, the other not so much but lacking in weight and leaving you in an apparent 50/50). As someone who’s been there but has made the crossing (or landed the jump, if you get the reference!), after years of bitterness and resentment towards ā€œā€œChristianityā€ā€ in my early childhood and about 15 years of ā€˜comfy agnosticism’, I think I could explain to a child (maybe a young and precocious teen going through his first ideological crisis?) what’s confusing them.

    I once tried making caramel by microwaving sugar cubes though, maybe the child could teach me something back, lol.

        There’s a barrier between what we hear and how we feel about it (which will then be expressed in words and action) and that’s the barrier of ideology plus self-beliefs (what we think). Plus, how mentally agile you are will decide on how quickly you reply (that’s why folks with ADHD can say and do some wild, impulsive shit, for instance). By analysing our beliefs critically and fearlessly, and tearing down the ideological house of cards that causes us cognitive dissonance and impedes us from reaching the right conclusions in many areas of our lives, we can better deal with the world and how it ā€˜makes us’ feel. Going from ā€œpeople are not to be trustedā€ or ā€œall women are sluts (but somehow they will never date me)ā€ to ā€œpeople are fundamentally good, but flawed to different degrees and in different ways and there’s no need to live in fearā€ and ā€œwomen and men are sexual creatures, most women are not prostitutes and this is just the way I’ve coped with my lack of success in the dating world and with the feelings of worthlessness and despair that come with itā€, for example, will 100% help you better handle your emotions.

        There’s nothing to do about mental agility though, I’ve found, besides being permanently medicated/sedated or high on weed. And none of those sound healthy/ideal. šŸ¤·šŸ˜…

        Oh, it’s just what I’ve noticed in myself, and others when I ask them what they believe in and the convo goes from there.

        It seems that in the end it’s one of two things… There’s what’s known as the Epicurean paradox or the problem of evil, where the confusion arises from many sources: forgetting about the existence of free will and the causal chain of events, semantic nonsense or even simple immaturity. This is the one that’s just all fluff, all wind, but words can kick one’s ass, especially if you live more in words than in reality.

        And then there’s the one that I respect a little bit more: while the beginning of the causal chain that we can conceive (so, embedded in/attached to space and time) is evidently not a source of it, but also since things exist today we can’t deny the ā€˜proto-thing’ existed then I can somewhat accept you telling me that this essence we call matter and energy was always there and God is not necessary and etc etc. God has been understood for millennia as the ā€˜prime engine’ and unmoved mover, behind the universe and before it, the One that ā€˜comes from nothing’ that we have to accept because nothing comes from nothing and things exist. But many folk just skip that part and say ā€œthings exist, that’s all I can see and that’s all I will believe inā€. That’s fair, but I better not see you making any logical inferences then, lol.

          Those two arguments are very biased. The first one is only a problem in Christianity, and like you said it’s a silly argument, God can be malicious and that solves that issue.

          The second one is a bit trickier, because you’re making the same mistake you accuse others of making. There are two possibilities, either something can come from nothing, or it can’t. If stuff can come from nothing God is not needed to create the Universe (and while physics have been able to prove this, let’s look at the other possibility just in case). On the other hand if stuff can’t come from nothing then stuff must have always existed, otherwise you will get the problem of where the stuff that did that came from, and that applies to God too, so of you can ask ā€œwhere did the Big Bang came from if there was nothingā€ you can also ask ā€œwhere did God came from if there was nothingā€, so in this scenario you also don’t need God, because if it can come from nothing then other stuff can also come from nothing so we’re in the other scenario.

          Also those are two of the weakest arguments against God, and they specifically go after the Christian God of the gaps. Better arguments against the existence of God are usually about pointing at contradictions in the definition, similarly to how you said nothing can come from nothing but made an exception for God, another example is omniscience vs free will (if someone knows what you will do then you’re not free to do different), or omnipotence in itself (can God microwave a burrito so hot that even he can’t eat it?), and if we’re talking about the specific Christian deity the fact that he needs an innocent blood sacrifice to forgive people should be a clear indicator of the type of being you’re dealing with, and it’s not an all loving entity.

            Eventually you’ll reach a stopping point. The believers go a step behind the nonbelievers, a step into the unseen, that’s all. Up until the beginning of the universe we’re all in agreement because things exist, lol. And there’s no contradiction in the definitions I’m using, that’s just semantics and often due to the Frankenstein monster of inconsistencies that’s Roman Catholicism and everything that came from it. You have to think about it without labels, the way the Greek philosophers did, and assume corruption in much of the remaining scriptures. And blood sacrifices? Are you referring to Abraham? God doesn’t require blood, just faith and acts, we’re not Aztecs! But if you believe in the unseen and in a judgment post death, you believe in life after death, and if you do and God Himself asks you to sacrifice your child, is it even a negative or are you, with 100% certainty, sending your kid to Heaven? Not that it’s an easy pill to swallow, there’s a reason Abraham’s name is known today, but that’s not because BLOOD FOR THE BLOOD GOD, but it fits as an acknowledgement of our ephemeral nature and ā€˜meaningless existence’ and a test of faith (everyone dies in the end too…).

            If you ever wanna talk about it in earnest, I’m up for a call. These convos are not very productive in this format, lol.

              Yup, eventually believers reach the same stopping point but instead of saying ā€œI don’t knowā€ they go ā€œGod did itā€, until science explains how that happened, so believers go to the next thing and say ā€œwell I don’t know how this happened, therefore Godā€. That is called ā€œthe God of the gapsā€ and it’s a terrible argument, it’s okay to admit we don’t know something.

              And no, I’m not talking about Abraham, I’m talking about Jesus, the whole reason why Jesus is crucified is so that his blood can clean the sin of mankind. The basics of Christianism are the following tenets:

              1. God can’t (or doesn’t want to) coexist with Sin
              2. God requires blood sacrifices, usually animals, to purify Sin
              3. God offered a loophole, by sacrificing an innocent person anyone can point at that sacrifice and say ā€œI’m using this sacrifice to purify my sinsā€.
              4. Because there are no Sinless humans he had to come down in human form to sacrifice himself so that he could charge the innocent blood price for the Sins of mankind

              Otherwise why would God need to offer himself as sacrifice to purify sins? Couldn’t he just say ā€œall sins are goneā€? However you look at it he asks for a blood sacrifice, however he allows you to cash in his own blood sacrifice in its place, and if you don’t he sends you to Hell, very loving fellow.

                I understand the concept of the ā€œGod of the gapsā€ but this is not about that. Our origins before the start of the universe is not something we can ever study or know anything about! Of course it’s a ā€˜gap in our knowledge’, but it’s a fundamental one, not one that can ever be filled. You make a decision to be on one of two camps: ā€œthings existā€ or ā€œthings exist, and that implies a Creatorā€. That’s all. And like I said, I don’t think there’s a ā€˜final irrefutable argument’ after that to make anyone believe in the Creator. It’s just a personal decision.

                And I don’t believe in Christianity, it’s a mixture of European paganism (including the winter’s solstice now called Christmas) and some Abrahamic/Mosaic superficial aspects and tenets besides the most important one: don’t equate anything/one to God. God is no man. I mean, if you’ve read the Bible (heavily ā€˜corrupted’, but the whole Roman Catholic religion was based in corruption and the co opting of a ā€˜Jewish’ religion movement), you’ll see that Jesus doesn’t even want you to call him ā€˜good’ (let alone God!), telling us that ā€œonly the Father is goodā€. Disregard everything you know about God that comes from whatever Western understanding you have of Him. Disregard anything Paulian (the actual founding figure of Christianity, and to a great extent why it’s a fucked up thing). If you’re really interested: read Ecclesiastes, read at least the Sermon of the Mount, read the Qur’an and make your own conclusions. The wise and inspired said all the same things in the end (ā€œfear God and keep His commandmentsā€, ā€œLove your enemies. Bless those who curse you. Do good to those who hate you. And pray for those who hurt you and persecute you, so that you may be the children of your Father, Who is in Heaven.ā€ā€¦) just with different accents. Nothing that’s nonsensical belongs to God’s system nor are they words inspired by Him!

This is the one that’s just all fluff, all wind, but words can kick one’s ass, especially if you live more in words than in reality.

          I am assuming we are speaking about the Christian God in this context.

          God is all knowing, and omnipresent. This means that God knows in advance the result of it’s own decisions.

          If God granted free will to humans knowing that humans would commit horrible acts with it against each other, how can that God be considered benevolent?

          And then there’s the one that I respect a little bit more: while the beginning of the causal chain that we can conceive (so, embedded in/attached to space and time) is evidently not a source of it, but also since things exist today we can’t deny the ā€˜proto-thing’ existed then I can somewhat accept you telling me that this essence we call matter and energy was always there and God is not necessary and etc etc. God has been understood for millennia as the ā€˜prime engine’ and unmoved mover, behind the universe and before it, the One that ā€˜comes from nothing’ that we have to accept because nothing comes from nothing and things exist.

          The question remains both Theologically and Scientifically unanswered: If ā€œnothingā€ can come from ā€œnothingā€, where did the ā€œthingā€ that created ā€œeverythingā€ come from?

          If we accept the Big Bang or Creationism as two theories explaining the same event from a different point of view, what was existence prior to that? Did God simply exist in infinite nothingness up until the point of creation? Wouldn’t the existence of God contradict ā€œnothingnessā€ simply by existing?

            The mystery is why He created anything at all, sure, but our existence and everything that surrounds us is a net positive, a free gift that we can always opt out of if we truly wish and bring it back to the zero that nonbelievers believe in. Nothingness is just a rope away after all, right? Every truly happy person out there, believer or not, sees it as the gift it is. God didn’t have to make anything, yet He did, and my life despite its hardships, created by other people, has been a very enjoyable experience. Now, the promise of God (yes, we’re talking about Abrahamic tenets here) is that of eternal life as long as you keep Him in mind and act right (pretty small price for some, seemingly impossible for others). In that context, sure, God is inherently, supremely benevolent (first you get a life for free that can honestly be great and you can always opt out of… although you can also suffer and 99% of it will be due to someone else, of course; but then you get another one that depends entirely on your own deeds and nothing else). But even without it, how could I reasonably blame God for other people’s amorality when, as a moral person or at least one who tries to be one, I understand it’s not that difficult not to cross some major lines? That’s it’s entirely in their hands and they just decided they didn’t give a fuck? That’s the immaturity I’m talking about. You might as well complain to your parents that they brought you into the world, lol, right? There’s no cause and effect chain here between my childhood bully, his abuse and God’s will, there’s just one between (for instance) his childhood trauma, lack of information on his situation, lack of self control, lack of reflection and, finally but perhaps more importantly, lack of empathy and ā€˜humanity’. It’s not ā€˜unfair’ that God endowed us with free will, it’s just the way He wanted us to be, for whatever reasons He had, and whether we like it or not (another function of free will, lol) it’s what we’re left with. And the world could be close to utopia if dads raised their kids, husbands didn’t beat their wives, Casey Anthony didn’t murder her daughter, of course! All we can do is invite people into morality and then reprimand/banish/incarcerate them if they poop on the invitation.

            For the second part: you’re thinking of God as a thing. Or even worse, as a man, maybe (Christians do this, probably due to their creed’s Roman origins, lol). God is not here, God is outside. The Creator cannot be constrained in its creation! It would mean that the creation came before the Creator, lol, which is obvious nonsense. And so this creation is at least a level beneath Him, and in the same way that Stan Lee is not carbon on paper and text bubbles, God is not matter nor energy. I can tell you that much with logical certainty. Whether you wanna stop at ā€œthings exist, at times in shocking order, and compose a chain of cause and effect that takes us to the beginning of time and space, and that’s all I can say with any degree of material certaintyā€, or follow up it up with ā€œand I believe that, because of this complex existence, a ā€˜higher level entity’ with more complexity than existence itself made it and sustains itā€, is up to you. I haven’t really found any connecting arguments or whatever, which is why I respect an agnostic position if you reach this conclusion, but maybe there are not and they are not necessary (belief can only happen in the absence of material information, after all [Jesus’ ā€œbelief in the unseenā€]). Also, there’s only so many things you can communicate through words!

              I rarely get into these sorts of debaters because they’re almost always pointless, however a few of the things you said made me want to answer this.

              You’re completely missing the point for the first argument, people can’t choose to fly or kill each other by staring, so if humans were created by God then any flaws in humanity, including but not limited to ability to suffer and cause suffering, is part of God’s design that he could have removed. In other words, if God gave people the option to cause harm knowing they would (omniscience, remember) then he’s directly responsible for everything bad that happens, it’s like a father that gives a sharp knife to a kid and tells him to go run and play with his friends. God could have prevented suffering to begin with, therefore the fact that it exists proves that suffering is part of his plan. If that’s the case then yes, you being bullied and your bully being in an abusive home is all done by design, which is very twisted if you think about it.

              As for the second argument you admit that things exist outside our universe that can affect it, if that’s the case you don’t need God to create the Universe, we could be the result of a collision between two extra dimensional rocks. And that’s sort of the point of that argument, i.e. that you don’t need God to explain the beginning of the Universe because whatever question you have about the origin of the Universe can also be directed at God (e.g. and what caused that) and whatever answer you give using God can also be used for a non-God answer (e.g. extra dimensional causes)

                Extra dimensional causes for creation, sustainability and order? Yeah, that’s what we call God, lol. And it has to be One, for actual reasons (read Ibn Arabi).

                And I know God could’ve made the human equivalent of calculators, but he didn’t want to. There’s no other way to ā€˜make people that cause no harm’. I mean, many of my sad memories involve only words, should God have made people mute? You can forget the hands too, lol. He wanted intelligent beings with freedom. He made a sandbox and put us in it. Everything you’re talking about is nothing but the product of human ingenuity (and even before knives we were using sticks and stones), and all the evil you’ve been subjected to is the product of the misuse of human freedom. We wouldn’t even be able to reflect on things like we are right now if it weren’t for it! You want a world in which PEOPLE are not people, and are disappointed in God, instead of being happy of being alive for free (and I assume you’re enjoying it because you’re an adult arguing online, not the e-ghost of a man who roped some years ago) and being disappointed in people misusing their freedom (if you’re a correct person as I hope you are you see how easy it is not to be blight on the world). It’s immature and the product of a misunderstanding of reality. And I didn’t have a bully, I was the ā€˜bully’! But I wanted to make it ā€˜relatable’. And yes, you can 100% act right after a very difficult childhood. Knowing this is how I know the people who in their adulthood are still misbehaving are simply being willingly lazy and dgaf and/or hiding their heads in the sand in cowardice…

                  Nope, just extra dimensional cause for creation, no higher purpose required, for all we know whenever two rocks collide in that scenario they create a universe.

                  Also no, you’re completely missing the point, if God is omnipotent he could have made humans to never suffer and still be free, in theory most Christians believe that Heaven is free of suffering, do you cease being yourself when you go to heaven then? Just because you or I can’t imagine a world where humans are free but can’t hurt one another doesn’t mean that’s beyond the realm of possibilities, and if your counter argument will be that then we wouldn’t really be free, I tell you that humans can’t explode someone by looking at them, so he already imposed some limitations on the amount of harm we could cause to each other, yet you don’t see this as less freedom because you just accepted that’s the natural state, I propose there could be a natural state where humans can’t cause harm to each other and are still free.

    I can teach anyone any board or card game so long as I can play it once on my own. In my 20s I used a local charity coffee shop to teach the entire graduating class of my small town how to play magic the gathering.

    I might be able to explain to them canning and gentle kids friendly food safety? Education is difficult and not what I’m good at.
