The stationary heat around the nucleus I speak of creates a gravity field. It is bound to the nucleus. Electricity in the electric shell is stationary conventional transferring heat.
Word salad.

But north and south are determined by the nucleus.
Nope.

I mentioned these merely to show a counter example of Bard's claim that all waves experience diffraction.
The pictures do not show waves.
What do you think they show?
Pulses.

hf is the energy of a photon. Obviously if you have more photons in a box, you have more energy in the box. That doesn't mean that energy is quantised, only that photons are.
Can you add radiation energy by half a photon?
No.
Because, as Alan said, phonons are quantised.

It does on a guitar, because the ends are fixed. You might somehow induce a travelling or compression wave with a magnetic excitation of a steel string but the resulting frequency (MHz) will be far too high to contribute to the "wide rich sound...."
I'd like to see the maths on that. Take the average guitar string as having a length of 1 metre and the speed of sound in steel to be 5km/sec

Quote from: hamdani yusuf on Today at 03:40:07
In energy equation E=n.h.f, you can change E with constant f by changing n.
Only if there's an interaction with something else.

Quote from: hamdani yusuf on Today at 03:40:07
Gravitational potential energy and electrostatic potential energy has no frequency in their equations.
Nor do they refer to a single entity. You need  a "system" of at least two particles for gravitational or electrical potential to exist.

That's a separate class of problems.

Some sources mention that n is the number of photons.
Which sources?
Quote from: hamdani yusuf on Today at 03:27:47
A universe containing only 1 photon doesn't allow anyone to exist, let alone to think.
Nobody said it did.

Well good luck to you guys! pretty stressful to be the first to say something so obvious.
It's obvious that you are wrong.
I didn't find it stressful pointing it  out.

elements that have cube numbers like 27 and 64, and their neighboring elements, make up the magnetic compounds.
Interesting idea, but wrong.
https://en.wikipedia.org/wiki/Heusler_compound

Also, we know that the magnetic properties are largely determined by the electrons, not the nucleus.

A numerologist would try to convince us that oxygen (with atomic number 8) is also magnetic but it's only paramagnetic and, of course, hydrogen (atomic number 1) isn't magnetic.

nobody has ever insulted me with the title of philosopher!
I had assumed you were a PhD.
But a gentleman wouldn't draw attention to it, surely?
I wasn't aware that PhDs were handed out by gentlemen.

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: Yesterday 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.

Why do you persist in posting this idiotic nonsense?
I think it's a medical issue.
