Renewable energy technologies (and solar especially) are about as important as oil was in the 20th century. America literally went to war multiple times internationally to get access to that sweet juice. It makes absolutely no sense that America would not want to have access to excessive amounts of cheap energy today, and that's why it is straightforward that America will do a 180° turn-around and start calling the Chinese their "best friend" for providing them with ample amounts of solar energy panels.

The social environments most people call "echo chambers" map entirely incorrectly to the metaphor of acoustic physics, whereas true "echo chambers" have the structure of something like a large cathedral...

...true sound absorption/anti-echo materials in contrast by definition include highly manifold structures with many internal divisions.

How does acoustic foam work? All we have to do to understand how does acoustic foam works is to look at the individual cell structure of the foam. You can see that the cell structure is open or porous in nature. This cell structure type allows for air to flow into the foam and enter the individual cells. Once it is in the cells, it moves around and this movement creates friction. We all know that friction can produce heat. If you have ever rubbed sticks together when camping to create a fire, you realize how friction works. Once the friction starts to produce heat, an energy transformation occurs. We do not lose energy, we change its form to heat.

It is well known that the acoustic absorption capacity depends on the acoustic porosity content (open porosity). Indeed, scientists have focused on materials with interconnected porosity, especially foams made from polyurethane [1], [2], [3], [4], [5], [6], [7], [8]. It is essential to determine parameters such as the airflow resistivity, tortuosity and acoustic porosity to understand acoustic phenomena.

this is a structure that deadens echos

Hear me out:

The only, absolutely only reason why people don't generally marry on the first date is to figure out whether they DON'T fit together.

So if you manage to figure out that the relationship is not going to work out before you get into real commitments (kids, mortgage, ...) you successfully avoided trouble.

I see it so often that people think that dating is already a strong commitment and that ending a dead-end relationship is a failure.

There is no shame in realizing the relationship is going nowhere and ending it.

I thought of this after reading the first example in the comm sidebar.

In elementary Microwave Math (the subset most people learn during the normal operation of a consumer microwave), there are two places, the seconds place and the minutes place. The seconds place is constrained to [00 - 99] inclusive for one hundred total possible values in that place. The minutes place can be constrained to the same set of symbols, in which case Microwave Math is simply a base one hundred numeral system operating in a base sixty place value system, leading to the mildly humorous situation of having two ways to represent the same numerical value, e.g. 01:20 = 00:80. Some microwaves may have an hours place, or different constraints on the possible values of the minutes place, for which we'll need...

Advanced Microwave Math! This introduces the concept of nested place value systems. Most of us are so used to place value numbering systems that we hardly notice how often we use them, but most numbering systems follow an implicit rule that the number of symbols is the same as the value of moving up a "place". This makes sense for counting because you don't need to move up a place until you run out of symbols, so you may as well make the value of the next place the next number you need to represent. Numeral systems don't have to follow this rule, and Advanced Microwave Math breaks it.

The simplest case is where the minutes place is bounded to the set of all non-negative integers. In this value system there are two places, each with their own rules governing which symbols are allowed and what values they can represent. the seconds place is constrained in value to 00 - 99 (decimal, or DEC), and has a place value of one. The minutes place might be constrained to [00 - 99DEC], [000 - 999DEC], or it might be that the minutes place can contain any non-negative integer.

After that, we come to the hours place, which functions more or less the same way as the minutes place, in that it can have various constraints on what values can be used, but it still has the same place value relationship to the minutes place of sixty that minutes has to seconds. This changes with the introduction of the days place, which has a value of 24DECxhours instead of 60DEC.

Expanding this system into weeks and months and years introduces the idea that, though the system is generally presented one with positional notation (the value of place n is some [usually fixed] multiple of the value of place n+1). This isn't necessary for Microwave Math, if each place can be defined by an arbitrary multiple of the of a base value e.g. the years place could be defined as 31557600DEC seconds (the "Julian Year"). The only requirement is that instead of position dictating the multiplier, each place must have a unique symbol denoting which multiplier is being used by that place. By convention they are arranged from largest multiplier to least, but 3 years, 6 months, and 12 seconds can just as unambiguously be written as 12 seconds, 3 years, and 6 months and refer to the same amount of microwave time (c.f. the American middle-endian date representation, a similar rule-breaking place value system that, if we insist upon using it, could really benefit from some non-positional place value indicator).

The value multiplier for a place doesn't have to be an integer either. The introduction of leaps (day and second) and other vagaries of calculating means that we might prefer to use a "mean" value where a year might be some non-integer multiple of seconds, depending on which period of earth's history one is in. There's no reason the multiplier has to be an integer, or non-negative, or real, or rational, or continuous or differentiable or have any particular reference to any other place. In addition, each place has its own rules about what values can be in it, and those rules may mean that each place can have infinitely many symbols representing infinitely many values.

The inner place value systems can themselves be a simple positional place value system like decimal, or they can themselves use Microwave Math, meaning that place value systems in Microwave Math can nest infinitely. I'm not sure what kind of number that is but Microwave Math has some crazy implications to it.

404media, The Intercept, Status Coup News, Where's Your Ed At, Andrew Callahan's Channel 5, Defector, the smattering of True Crime podcasts and journals... increasingly, it feels like if you want to know what the hell is going on in the world, you have to go to some indie website or YouTube channel with six substack reporters in a trench coat.

As a consequence of the mainstream NYT / CBS / BBC going to shit, they're the only outlets that stay current and do in depth coverage anymore. Everything else is either reactionary propaganda or AI slop.

Just being the last credible news sources standing seems to have an impact, as more people crowd in on the reliable venues for news in the void created by professionalized for-profit corporate media.

Watch for this behavior and you will see it often.
If a Lemmy user can call out the age of an account he or she will use that as a way to dismiss and degrade the post that he or she does not agree with.

Y'all would enjoy Lemmy a lot more if you just focused on the post and stopped feeling compelled to rummage through someone's post history.

Sure, if that person has extreme political views, is a Nazi, or is astroturfing then maybe you have cause but clicking every single profile to find dirt to make an argument showcases your poor debate skills.

Also that there's a conspiracy from the atheist tech elites to ruin Christmas by making electricity so expensive no one wants to put up Christmas lights
