Oh dear, other enlargement problems as well ...

I'm very sorry to hear about the high blood pressure, Bob, there was a young bloke when I was starting in IT, early 20's and his system was being pounded by the drugs they were using to try and get the pressure down, it was a nightmare for him.

Guess you will just have to try harder to "hang loose", you gotta work at it, focus, focus !! ... 😀

Take care ... 😉

Here are some lyrics for you,

Eclipse Lyrics - Pink Floyd Lyrics


http://www.youtube.com/watch?v=El2l__hRta0

All in all we all going to die soon or later, so might as well enjoy the little time we have on this planet, and get along with everyone else, no matter what our differences are and ages and experience and bank account sizes and what kind of audio gear and loudspeakers and all that blues.

Perhaps that's the illusion we (the human race think it matters). In Billions of years to come, perhaps there will be a realisation that mans ego is a fallacy.

Lol, it's full of princesses here where I live. ...And they all lookin' for their prince, me. 🙂
Time for serenades on my guitar ....

The universe is expanding fast; we have to jump in before it's gettin' too large.

Life is beautiful (some places on our planet), and then we *** 😀
It's ok though, because our great great great great great great grandchildren will keep asking the same question as us: What is the Universe expanding into?

Don't give up, don't ever give up; grab some gravitons whenever you leave home.
Patent something that can emmagazine few of them; they'll become real handy when time comes to lift ourselves from above ground.
...Or to get down back to earth, on solid foundation, with a higher spiritual level.

If we regard matter as made up of charged particles, there can be no magnetic moment in the state of thermal equilibrium in a strictly classical system, even in the presence of an applied magnetic field, regardless how big it is.

Thus magnetism is essentially a quantum effect.

but matter are no matters unless you observe them. they are all waves.

look at the slot experiment of physic quantic. particles only exist if its being observed.

Once observe, I personally couldnt care less what happens to that ``made up`` particle. ultimitely, theres no partical, only waves and movement.

Isnt that due to the torque of the EM force in that it is of too high value to be influenced by magnetic fields with the intensities we are experiencing in our experiences and that the effect is counted as about negligible or even non existent if this influence is effective only over a given level/barrier potential..?.

If we look at the strength of the EM force the repulsive torque between two sets of about 0.5 grammes of electrons each has same strength as the weight of an earth weighted at 1 metre of the ground, given the extremely low distance between electrons and kernels all the force is inherently confined at the atomic level, the magnitude of the necessary magnetic field to break those links is well above what we encounter in our world and close universe, hence in our theorical modelisation we can safely assume that magnetic fields are of no influence but it could be like the ohm law, that is, an approximation that has validity only in a limited range.

Actualy the only mean to break this link is to use another magnet, that is, another electron, at close distance the repulsive torque will force the electrons to distance themselves thus giving existence to what we call chemical reactions and wich, you know it of course, are macro EM reactions.

I forgot to specify that distance between the two 0.5 grammes sets of electrons is 1 metre, 0.5 grammes of electrons is the quantity in 1kg of hydrogene, so we can conclude that the sum of all individual electrical torques in 2kg of protons made matter is equivalent in strength to an earth weighted at 1 metre of the ground.

Even more, the Bohr–van Leeuwen theorem proves that magnetism is a quantum mechanical effect; it cannot occur in purely classical solids because electrons in a material do not interact with an applied magnetic field.

Does this apply if magnetic field intensity is let say 10^11 Tesla.?.

It seems to me that you did not understand my point from the beginning, let me explain again with a little rough demonstration, because my Tarzan-English obviously doesn't help.

The Lorentz force on a particle with charge q and velocity v is

F = q [E + (1/c) v x B]​
Hence, the work done

F . v = q [E + (1/c) v x B] . v = q E . v​

Does not depend on B

For a classical solid, from statistical mechanics, it follows that the magnetic moment in thermal equilibrium remains zero in any magnetic field.

Then, statistically, electrons do not interact with an applied magnetic field, and magnetism is a quantum effect.

This is a classical-quantum mess, if you go to an “electrons store” and ask for about 0.5 grams of electrons, they will sell you “free electrons” with spin, hence you can not construct a classical solid which needs spinless electrons.

What a relief, hydrogen saved us from going to the electrons store!

Nevertheless, I agree that EM force is about 36 orders of magnitude greater than gravitational force.

There are certainly other lifeforms in the vast expanded horizon of the universe.
We are simply not "calibrated" (evolved) enough to even know where to start looking for.

We are less than nothing in the grand scheme of all things.
It's like being invisible to our own images.
