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.

Why?

We traded energy cost for time when we stopped walking, and replaced it with an animal and a cart, and again with cars, and airplanes. We save time, but the energy input is greater.

Who’s to say that teleportation wouldn’t be a trade off between 5x the energy to take a jet, but instantaneous?

Digital goods aren’t physical; teleportation is physical.

Considering that
Power = WorkDone / TimeTaken
and lets just say for this instance that WorkDone is same for the jet and for the teleporter^[because calculating work done in such a scenario is kinda hard], which is kinda wrong, but won't matter anyway as you see further.

Then,
Power~teleporter~ = Power~jet~ × TimeTaken~jet~ / TimeTaken~teleporter~

then going with "instantaneous"

With limit(TimeTaken~teleporter~ ⟶ 0)

Power~teleporter~ ⟶ ∞

Now, someone will ask, what if WorkDone in case of teleportation is actually close to 0.
But that won't happen, simply because the minimum value for WorkDone in that case would be equivalent to the change in gravitational potential, making it a significant amount as compared to the other limits.


Oh and digital goods do have an energy cost, btw.
