Trying to understand a concept isn't the and as arguing. Also, you may have lead with the major in physics.

As stated, I only draw from my experience. That is articles I've read and videos from SciShow and the like.

If I hold a metal rod with a metal pair of pliers and heat the far end of the rod, the piers will heat up from hear transfer.

That's about as far as my understanding of thermodynamics goes.

I have never heard of plates having resonant frequencies as microwaves. That, however, does not mean it's not true, only that I have more to learn.

Not true, the cough syrup with dxm and acetaminophen will get you tripping balls and throwing up cherry flavored disgustingness. Spend the extra money and get the dxm only.

When it is that hot, any relief, however fleeting, is appreciated. Alcohol will flash off, but takes some of your body heat with it. It is enough to help if you are having problems falling asleep, and if you're awake, slather on some more Alcohol when it dries.

> thinking with sound is exactly how we ended up here

While everything you said is true, the speed of sound, which, yes, is much slower than light, is still pretty damn fast when we're talking about how much time there is to process something in the time between a soundwave passing from one side of your earbud to the other. Right? Cuz that's what we're talking about. Not how long the sound of something vs. the light of something takes to hit your brain.

Ultimately what we're talking about is that the earbud needs to be able to detect the soundwave, compute its opposite waveform, and emit the counter wave all in the same time that it takes for the soundwave to pass the earbud so that the original wave and the counterwave hit the eardrum at the same time. Right?

So if we assume the earbud is maybe half an inch thick, means it has to do all of that in about 1/27,000th of a second. 0.04 milliseconds.

Even knowing how fast sound travels, that ability to process seems unintuitively quick. That's all I'm saying, it's unintuitive and pretty darn cool.

Most of cabbage is cellulose, which we tend to call fibre. Our bodies can't digest it so it passes through our system and is pooped out.

Chocolate bars are high in sugar and fat, things our bodies absorb very well so, all other things being equal, you retain far more mass from the chocolate bar than from the cabbage.

The lungs of fetus are not working like they will after they are born. They are not responsible for oxygenation as this is done by the mother's body.

The lungs are designed to function with gravity during inhalation and exhalation is caused by the elastic nature of the lungs.

When a person is inverted for too long the cause of death is asphyxiation.

Think of it like a super rare pokemon card of Charizard. That’s valued at 1 Billion. Later on people care less about pokemon cards though so the value decreases. What they lost was the value of an asset.

This can be bad for the pokemon merchandise market though as people are less interested they buy less cards and other goods.

Later the popularity could go up again and the value of Charizard could go back up.

If they ever sell the card then thats when the price is actualized.

But in practice no company can pay a trillion dollars to buy a large company like amazon. But those companies make tons of profit over their lifetime which is why they are valued so high.

Some times it’s just not possible. Incentive comp hits EBITDA. There may be some bank covenants or loan requirements that need EBITDA to be certain amount or be above certain ratios or have certain amount of cash/AR on hand. There maybe a fee the company has to pay to the bank or lender for not being in compliance or even complete payback.

Yes, it causes the water molecules in the food to vibrate, but if the plate has a similar frequency to the water molecules, then the plate can heat up too.

And yes, if you have a plate that generally heats up more than the food, you can put it in the microwave and it will heat up.

Why are you arguing instead of listening? I have a major in physics engineering, I know what I'm talking about. Your explanation literally violated one of the basic thermodynamic laws.

Seems like Dunning Krueger effect in action.
