Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

1D and 2D are just mathematical abstractions. Everything is just 3D and that's it. There is no time, just space with a state.

(I tried to explain better in comments so please check that. I would be glad if someone could give me a response to this brain fuck I’m having)

Yes, they are only abstractions, just like numbers are. I do not understand your conclusion that they therefore do not exist.

I still upvoted this, because I can see where you are coming from. It's frustrating when adults portray thin flat objects as "2D objects" to explain dimensions to children. It's not a simplification; it's simply wrong.

I get what you are saying, but it is not wrong. It is not even a simplification. The surface of any object is 2D, and the surface of a flat object is the simplest form of a 2D coordinate system.

What I meant is that some people portray the thin flat object itself as a 2D object, e.g. a piece of paper opposed to a box. I do understand that it's intuitive to associate the absence of a dimension with a value close to 0 for it and vice versa, because that's how we visualize it.

I haven't heard anyone actually claiming that a piece of paper has zero thickness before.
