Reply to comment by zachtheperson in ELI5: How exactly does heat increase the kinetic energy of particles? by LevelMedicine3539
i could be wrong but i think the ops question is something like this....
if you put a flame under a piece of steel, the particles in the steel move around faster, which we feel as heat.....but why does the flame make them move faster?

Heat is the kinetic energy of particles. The more they move, they more they bump into other particles and knock them around as well, "heating," them up.

A hot object has fast molecules, i.e. molecules with high kinetic energy. When it touches a cool object (which has slow molecules), its fast molecules randomly whack into the slow ones and make them move faster, increasing their kinetic energy.

Maybe that was part of the joke.

That was something that annoyed me in the pilot episode of The West Wing. One of the characters is loudly complaining that the New York Times crossword puzzle misspelled the name of the Libyan leader at the time, Muammar Gaddafi. Unless you’re writing it in Arabic script, there is no one right spelling.

Oh. I see. Thanks for explaining.
Seems like more of a manufacturer “shoulda accounted for” instead of a “customer could fix if they want to” kind of thing.

Writing the sounds of one language, into the text of another language is called transliteration. It happens naturally, when people simply write what they hear, when listening to a native speaker use words or names in the original language. There's also standardized version of it, to ensure the same spelling for the same word. In some languages it's more common to use standardized versions than in others.
When it happens naturally, before a standard version become popular, you can end up with multiple spellings and pronunciations of the same word. For example, besides the most common "Japan", the name of the country has been written as Nifon, Nihon, Nippon, and Jippon.

Static (stationary) friction is stronger than kinetic (sliding) friction. In other words, once two objects start sliding past each other, the friction between them is less than before. Also, once motion has begun there is momentum which will tend to keep it going.

In general, when translating names from a language that uses characters to one that uses the Latin alphabet (such as English), the translator will usually try to use letters that are as close as possible to the original characters. For example, if the name is written in Japanese, the translator might use "K" for "き" and "M" for "ま". However, there is no single standard for this, so the translator has some flexibility in how they choose to represent the name in English. Ultimately, it is up to the individual to decide what letters they prefer, as long as the result is still easily recognizable.

A lot of languages have "romanization" schemes- ways to write the language using Roman or English letters. Chinese uses Pinyin, Japanese uses Hepburn, Arabic uses a collection of formal and informal ones, and so on. These tend to be somewhat systematized so there's a degree of standardization.

Yes, and other factors too of course. Physical characteristics of the components, size, shape, material composition would affect this as well. I could hear the noise quite well, since the circuit board was fairly flat and made for a good speaker surface. The power supply manufacturers have their own agendas for their designs. Power efficiency, large power output, ability to handle transients (large sudden changes in power demand). They attain these characteristics different ways, so some may have these issues because they used method A, while method B produces a similar result, but with other tradeoffs.

The Japanese specifically use Romaji which is a standardized phonetic transition from their characters/phonetics to the Latin alphabet that we know and love.
Other languages have different systems.
Some of them do guess, though. There are more languages than there are standardized systems.

Thanks. Yeah, I’m going to look into the mitigation as others as mentioned as well.

Thanks for your explanation.
So we can mitigate coil whine with coating the coils? Someone mentioned hot glue and you mention silicone…
I’m going to see if I can find more info on this.

Could that be what people mean when different power supplies are better or worse for coil whine? Just different frequencies or power ratings?

Thanks for the explanation.
I’m going to look up some more on the hot glue thing. Don’t want to ruin anything, but I’m intrigued.

Mostly conduction, meaning the particles of the hot gases of the flame are moving very fast and keep bumping into the steel particles.
