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.

If the information is stored at some value of bits per cm... There's less bitrate (bits per revolution) in the middle of the record vs the outer edges.

I always assumed that the initial cutting of the record accounts for the variation in speed as the needle moves towards the center. If that's the case, the information density would be relatively consisten, because the size of the bits of information would get smaller as the speed increases. Like a second of the song could be measured in radians, with the centimeters on the arc getting smaller. But I don't actually know if that's how it works.

I checked, audio quality can degrade at the center, I guess since the needle can't read fine enough details. Also probably why the label size is similar on full size records and singles...

Yep its called IGD or inner groove distortion , reason why old albums almost always had the quiet ballads at the end.

Rush 2112 has real bad igd because it ends very loudly.

I'll find a copy just to hear for myself, that's neat

Absolutely, I hope the reissue LP is a reasonable price we'll see

They pressed a lot of them, shouldn't be more than $20 even for an og

The angular velocity is always the same during recording and playback

So the arc speed increases as the radius decreases, both in cutting and reading.

Lines and angles and curves, too, I bet.
