New Theories / Re: Where does quantization of energy of electromagnetic radiation come from?

Quote from: hamdani yusuf on Today at 12:05:31
Afaik, it changes the energy by affecting the frequency
The statement is meaningless.
How could it affect one but not the other?
The statement is meaningless.

There's no adequate justification to extrapolate it to other type of power or energy, such as gravitational potential energy.
Do you know that gravity affects photon energy?

When power changes, where does the difference go?
You tell me.
I charge a battery slowly at a low power overnight, then, in the morning, I use that battery to deliver a lot of power briefly to start my car.

Where did the "extra" power come from?

Essentially any time we talk about "energy storage" we are using it to change power.

Just Chat! / Re: Heat-Treating Rubber Bands...
« on: Today at 08:43:26 »
What trashes rubber bands is mainly oxidation. If you wrap them well they last for ages.
Light (especially UV)  is also a factor; I assume it's dark up there.

I would say the north arctic is like a chimney for heat to escape into space.
And you would be wrong, as is often the case.

In currently more common used form of equation, radiation power is not quantized,
And that's fair enough because power isn't quantised in the way that energy is.
Power isn't even a conserved quantity.

So the sun's heat keeps earth a steady temperature, then burning of fossil fuels is adding the heat moment to moment that is causing a warm up.
It's causing "a" warm up; but not "the" warm up which, as has been pointed out is 30 times bigger.

Why do you persist in ignoring this simple fact?

I'm not sure if trying to cite a chat bot  on a science page is more or less stupid than trying to cite the Bible.
Quote from: Europan Ocean on Yesterday at 03:38:04
It's important to note that absence of evidence does not necessarily equate to evidence of absence.
How can you sleep at night knowing there might be a tiger in your room?
I realise there's no evidence for the tiger but you don't think that the absence of evidence equates to evidence of absence.

In the real world, if you look for evidence without finding it, and the situation is such that evidence should be obvious, then the absence of evidence IS evidence of absence.

My stance is that the aether doesn't exist at all.
why does an aether have to exist for my temperature theory to be true?
You don't have a theory; you have a guess.
And it's wrong.

"It would have been impossible for religion to exist before we had a society that was "rich" enough to support a bunch of preachers."
Ok. Your observation might need some actual history, though. As in, how did a society become rich? What constituted wealth during say, the early Neolithic before agriculture was around? How did hunter-gatherer societies become settled, or why did they?
Unless you are suggesting that the Lord provided food and shelter directly to the priests, it figures that someone else did.
So society must have been able to support preachers in order for preachers to exist.

People will have had all sorts of odd beliefs about their world, but it's when you get specialists in such faith that you get "religion" as a thing..

Classical theories don't tell where the quantization of energy comes from.
In fairness this is true.
It's more or less tautology because, in this context , "classical" means "not quantum".

(Rather than between the Baroque and the Romantic periods)

I'm sure you could calculate the precise acceleration of a flat-screen television in a 3T field,
Quite possibly zero.
Quote from: Eternal Student on 05/06/2023 17:01:50
So it experiences a force that depends on the gradient of the B field instead of being directly proportional to B

If you don't have evidence to support it, that would just make it a hypothesis, not a theory.

Also, what would you do with the water in the smoke stacks once it absorbed the heat? Remember, heat can't be destroyed.
This is why I asked if oscillations of the atom's in the hot water release energy. I guess the question is when you pour boiling water on the ground does 100% of the heat re-enter the atmosphere? or does it dissipate downwards? into the denser cooler earth?
Do you understand that the deep earth is very hot?
You can't expect heat to soak into it because heat is always coming up from it.
That's why geothermal energy is a thing.

And now, once again.

What do you mean by this?
Quote from: trevorjohnson32 on 03/06/2023 20:45:18
50% of the energy of an explosion iss converted into blast energy which is further divided into seismic, sound, and weight displacement. None of that hurts the atmosphere.

It would have been impossible for religion to exist before we had a society that was "rich" enough to support a bunch of preachers.
I've thought about the recent archaeology around the Anatolian mountains; Catalyohuk, Gobekle Tepe, to name two of them.
These were built during the Neolithic and supported by hunter gatherers, presumably they were coerced into doing this.

Later, all these settlements, which arguably were some of the first temples and the first elite societies, were all buried and not by natural means. It was deliberate.
It's remarkable that Neolithic peoples went to all that effort building them, sustaining the people who chose to live there and not hunt, and then burying them. You have to ask about what the motivation was.

Religion is a modern word, it probably started out when the Romans adopted Christianity. The idea of a state religion or religious practice wasn't novel back then, but the Romans of course exploited people's beliefs. Before Christianity, Romans  were quite ambivalent about the intentions of their gods.
So?
So, if the modern version of whatever it was when we first started doing it, is exemplified by Christianity and how it, evolved, as the cultural idiom saw fit; then has that religious doctrine, the churches in Rome and Constantinople and all the history meant the end of civilization, or made any difference? Compare what Romans believed before and after certain events, including the end of the Empire, but not the Church.

It became a powerful enough institution that it could dictate to kings about what they were allowed to do. So that must have all been quite influential, I'd say.
None of that in any way undermines my observation;
"It would have been impossible for religion to exist before we had a society that was "rich" enough to support a bunch of preachers."
 does it?


So why quote me?
