Everyone has something they can't stop themselves from nerding out over - but often it's hard to find people to talk to about it. So go ahead, share your interests, and tell us about them!

The idea of time. It’s insane to me to think about events happening at different times in different places. Or for the same event to take different amounts of time depending on your reference points.

The sun is 8 minutes away from us, so we are looking at it 8 minutes in the past. If it were to suddenly disappear, it would take 8 minutes for us to find out. That’s mine-blowing to me! It’s like the past, present, and future are all happening at the same time.

Nobody cares to humor me when I bring the topic up lol

[–] sep@lemmy.world 7 points 1 year ago (2 children)

So facinating, even gravity is affected by those 8 minutes. Iow we would rotate around a missing sun, for 8 minutes, same as with light.
This is all also related to relativity, that someone else wanted to talk about in this post, i am just saying ;)

I'll humour you! Time is fascinating and malleable and really quite intangible.

So, if you want, fire away with anything you find fascinating about the concept of time!

I've thought about something related.

In one point of view, time traveling to the past can create paradoxes since it alters events after that moment in the past, which could cause you to never time travel to the past after.

After some thinking, I got the feeling that the fixed-point theorem was connected to this. As long as whatever you do in the past causes you to time travel to the past again and do the same thing in the future, the paradox doesn't happen. What you do when you time travel is like the input, and what you do when you time travel again in the resulting future is like the output.

When the input and output are the same, everything works out.

After searching about this on the internet, I saw other people have thought about and discussed this.

At the risk of sounding edgy: Sex.

I live in the US. Sex, even just plain boring vanilla sex, is such a taboo topic. Everyone's uncomfortable about it, and that sucks. I think it's interesting, and fun, and there's so many things to talk about from actual activities to social constructs and more.

Whenever it comes up, I nerd out the same way I would when talking about a game I am currently obsessing over.

Honestly? Myself. No one in my life asks how I'm doing, what I'm doing, if there's anything new... Then again I'm too much of a pushover anyway.

I'm an American who has been living abroad for 7ish years now. I often read comments from people who say they would do it "but the taxes are brutal." Absolutely not the case. I dug deep into tax programs when I left and can comfortably say I am better off financially now than at any time I ever lived in the States.. A major part of that is my tax strategy.

I love talking about this but most people don't really care or realize how significantly it can change their lives.. Eyes just tend to glaze over.

I'd honestly be interested in listening if we lived in the same area. I'm a total noob when it comes to anything beyond basic money management. I hope you find people who appreciate your insights!

I don't know if "rarely" is quite the right description, but I foster kittens. I meet lots of people who are excited to hear about it on a surface level and see pictures/videos/play with them, but it's been challenging to connect with other people who also foster. I'm desperate to trade stories, learn from, and teach other foster parents. I even started a community on Kbin and have posted there a few times, but haven't gotten any engagement (other than votes) so far.
In case anyone is curious, I'm still confused about how to properly link cross platform, but it's at fosteranimals@kbin.social

Instead of complaining about the public educational system. How to improve on existing methods to spread ideas of curiosity and learning methods/mechanisms through FOSS means.

[–] Foreigner@kbin.social 10 points 1 year ago

Lots of things I'm really interested in are looked down on by other adults I know. I love animation but it's seen as something for kids. I love video games, but that's for teens, incels and nerds. And I love birdwatching, but that's for boring old people. Oh and also whatever my ADHD is making me hyperfocus on at any given moment. I could talk about any of those topics for ages, but more often than not people aren't interested, so I keep it to myself.

benefits of ritual and separating them from superstition.

I think it's interesting to explore different frames of mind. I used to be christian, but then I read the bible. afterwards, I embraced paganism which has a more positive and welcoming community generally. eventually, the seeds of reason became rooted in my mind and I grew to be the atheist I am today. I still appreciate the experience of group ritual, as it feels good to explore different aspects of my personality. I guess the roleplaying is therapeutic. mixing that with my interests in mythology makes for plenty of content to examine. what encourages different rituals to develop? what are the notable effects of ritual in general? is superstition somehow beneficial to the community? I find that digging around to explore these questions can keep me busy for hours, which I enjoy thoroughly. unfortunately, no one I know shares the same interests. most folks seem to be superstitious about it, lol.

[–] RoquetteQueen@slrpnk.net 5 points 1 year ago (1 children)

I've always been an atheist but I come from a Catholic culture and have thought about this a lot. I feel that religion is kind of like ancient group therapy and the practices have a positive social impact. Gathering once a week with everyone in your community, singing songs and talking about how to be better people just seems like a good idea

Smacking children and how it literally has no benefit to the child whatsoever, and makes you a bad parent if you still do it.

I used to be a strong supporter of smacking kids, I even signed a government petition to revoke the NZ anti-smacking bill, but after studying it at uni and then keeping abreast of the research afterwards, it has only negative effects, and yet bad parents still defend it.

Hard to talk about because people get weirdly defensive even when there's NO evidence that smacking kids is either beneficial or effective.

Metal.

Soil.

Metals in soil.

What do you want to know?

[–] FooBarrington@lemmy.world 5 points 1 year ago (1 children)

What are metals people wouldn't expect to find in their local soil?

Are there processes to extract most/all metal from soil?

What are the coolest properties of metals that you know?

[–] Track_Shovel@slrpnk.net 4 points 1 year ago

What are the coolest properties of metals that you know?

Hah. I see my mantrap caught someone. I'm talking about metal bands in my first bullet (lmao), but elemental metals in my other two.

Metals are generally rough to remediate because they are inherent to the soil parent material (rock) that the soil developed on and the geochemistry of that rock. It's kind of like trying to take carbon dioxide out of the air; you can do it, but it's not easy and there is a chance your changes will be short lived.

Typically removal is done through phytoremediation, or by trying to stabilize soil metals in situ so they are in non-bioavailable forms.

Generally the ones most people (public) don't expect to see are lead, arsenic, copper and molybdenum. There is a mineral called Galena that can be common sometimes and a large source of the first two metals.

The theory of relativity (special and general).

It is more that 100 years now, and it is perfectly true according to all current physicists, but still hardly anybody (outside of physicists) knows it. What a shame.

For example, GPS wouldn't work without it - your position would be wrong by a few miles all the time.

Wow damn, this hit home. It always feels like everyone is just waiting for their turn to speak when I am talking, so I eventually stopped having things to say unless it's a joke or a pun.

My topic failure - My son totally nerds out over amplifiers and guitar pedals. He frequently tries to talk to me about noise and resistance and power supplies and other words that i can't even remember. I really want to listen but i know my eyes glaze over and he gets irritated.

[–] Otakat@reddthat.com 3 points 1 year ago

Try to find some closely related topic that you find interest in that he can relate to. Maybe old music or some other electronics topic. Then your son can meet you in the middle.

The difference between town, zip code, school district, village, hamlet, and city where I live. I pay taxes to town A, by zip code is named after a hamlet in town B, our school district is named after town C. If you ask people where they live they will answer any one of these things.

In my opinion the town you pay taxes to is the best answer. The zip code, or location on your address, is deceptive because they are often named after small hamlets where the post office is. This small hamlet is a very distinct place where you probably don't actually live. School Districts are often named after the biggest town they pull from so if you are not from that town it's not really accurate. If you happen to be in a city or village that's a good answer. However hamlets are so small and local that anyone not from the immediate vicinity will have no idea what you're taking about if you say you are from there.

The municipal waste management industry.

I even learned game dev in unity so I can work on a game about the waste management industry.

For context I dont even work in that field.

Psychology and physiology.

I swear my neuroendocrine system’s a lemon. I’ve had to learn basic and not so basic maintenance just to get the thing to run well enough to keep a job. I’ve struggled my entire adult life, and along the way I’ve learned a lot about trauma, stress, energy metabolism, brain parts, neurotransmitters, hormones, nutrition, inflammation, healing, spiritual work, things that alter the Big Five more than the literature says it will alter, etc.

I wouldn't call myself a Fnaf fan, but honestly I love the lore. Reading into it reminds me a lot of those kids in school who knew every detail about the Bionicle universe. I'm glad kids have something like that to get (reasonably) into.

It's also genuinely getting people into animatronics, both for restoring existing ones and creating new designs, which is pretty damn cool.
