As sound travels through a water layer where the speed through which it travels varies with depth, the sound will tend to refract towards where it is the slowest.

A layer where temperature decreases as depth increases will refract sound downwards. A layer that has the inverse temperature properties will do the opposite. A layer that is isothermal (where the temperature remains constant as depth changes), will still tend to refract sound upwards because the increase in pressure also increases velocity, although not as strongly as temperature does, which is why temperature differences can easily overcome this effect where the water is not isothermal.

If you have a layer that refracts sound downwards on top of a layer that refracts sound upwards, you just created a sound channel, which acts as a wave guide in which sound will remain trapped and travel far longer distances horizontally before dissipating.

Ultimately you can’t really put a number on the required temperature differences because there are many other factors to take into account like how steeply the speed of sound changes, how tall the layer(s) are, what is the frequency of the sound, or how much of it you want to remain “trapped” in the sound channel.

How well sound propagates through water is highly dependent on the water temperature variations over depth. There can be conditions in which sounds can be trapped between two different horizontal “layers” and travel far greater distances than 80km.

A lot of stock photos are ridiculous like that

Treat yourself with a nice new fast SSD and install it on that. Dual booting on the same drive is asking for Windows update to “randomly” nuke your bootloader.

People keep talking about terraforming Mars while we can’t even stop ourselves from reverse-terraforming Earth.

I did it soon after switching to Linux Mint from Windows because I didn’t like how Cinnamon was handling multiple displays. It worked and was perfectly functional. But it was a little rough around the edges with the occasional glitch here and there. Not sure if it was because Mint wasn’t really meant to run Plasma or if it was just because it was running an older version of Plasma. But it was perfectly usable and I would have been happy to stick with it if there were no other solutions.

Before I got too comfy in my Mint install and after having familiarized myself with Linux better, I hopped between a few distros for a bit. LMDE6 with Plasma ran better but ultimately I switched to OpenSUSE Tumbleweed and stuck with it since then. It is rock solid and runs Plasma 6. I should probably have given EndeavourOS a try as well but I’m now too settled and comfy to change.

Mind you, I am still a complete Linux noob and still have barely any idea of what I am doing so take it with a grain of salt.

I just can’t wait for 6.1 for the screen corner boundaries on multiple monitors. It’s the one feature that has been missing for way too long.

There should be a legal requirement to call a targeted advertisement a targeted advertisement. Being allowed to call them “recommendations” only makes these assholes feel emboldened to push ads where people wouldn’t normally accept them. Microsoft is pulling that dirty trick as well.

Thanks for letting me know. Just blocked lemmy.ml from my feed.

Big dumb corporation doing big dumb corporation stuff. It’s so big it can’t behave coherently anymore. But it’s also so big that it acts like a black hole that sucks all the money towards itself regardless of how stupid, unproductive and wasteful it is being.

That’s a typical case of someone who is so eager to sounds right in an argument that they will not bother double checking to see if they missed the original point or true meaning before replying.

There are a lot of people like that on Reddit. Well, I assume there still are I deleted my account a while ago. What a toxic place.

I was hesitant for a long while and ended up installing Linux Mint on an old SSD I had laying around this way there was no commitment.

Now I’m realizing I haven’t booted up my regular windows 10 drive ever since and am considering getting rid of it altogether.

On a side note I created a virtual machine on the Linux side that runs Windows 10 LTSC on it for a few other programs I sometimes need that would be very difficult or impossible to make work on Linux like Inventor, Office and Photoshop. It lives trapped in the box and isn’t allowed to connect to the internet. If I need to download something for it I download it on Linux and drag and drop it into the box. It’s like having a little pet Windows that you keep locked in a pen, so it works for you and only for you and it can’t escape to go into your house to spy on you and shit bloatware all over your carpet.

Could it be some sort of meta joke where the reviewer is mocking how the paper is written by imitating its bad writing style?

In zero gravity this is a legitimate concern

Sometimes I pretend to take sarcasm or joke statements seriously because I don’t know how to react to it otherwise.

I’m pretty sure mine hates me and makes me so stupid stuff whenever I’m distracted.

No price, no sale. I tell myself that whenever I have to walk away from a product that didn’t have a listed price.

This reminds me a lot of that one episode in the 60’s show The Prisonner where the protagonist is being labeled as “unmutual” by the others.
