What topic do you have the most knowledge, and can you explain it so a child can understand it?

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 '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 'prime engine' and unmoved mover, behind the universe and before it, the One that '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 "things exist, that's all I can see and that's all I will believe in". That's fair, but I better not see you making any logical inferences then, 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 'makes us' feel. Going from "people are not to be trusted" or "all women are sluts (but somehow they will never date me)" to "people are fundamentally good, but flawed to different degrees and in different ways and there's no need to live in fear" and "women 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 it", 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.

Business design and operations. I can't even successfully explain it to adults, let alone a child.

Early childhood development and history, and no, while the whole point of my degrees is how to teach children, I cannot teach how to teach children to children.

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!

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 ‘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 ‘prime engine’ and unmoved mover, behind the universe and before it, the One that ‘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 "nothing" can come from "nothing", where did the "thing" that created "everything" 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 "nothingness" simply by existing?

Hey I got a PDF on electrical work from my online electrician course I can give you. If you're at all mechanically inclined you'll have it down pat by the end of the book.

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.

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.

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 'humanity'. It's not '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 "things 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 certainty", or follow up it up with "and I believe that, because of this complex existence, a 'higher level entity' with more complexity than existence itself made it and sustains it", 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' "belief in the unseen"]). Also, there's only so many things you can communicate through words!

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.

"Smart City" 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.

There's lots of other computer science topics I know very well (AIs being one of them funnily enough) but even I would zone out if you didn't bring a little attendance present and a live demonstration when I need to listen to you explain it.

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.
