The beauty of Maxwell’s equations can be seen in how it helps us understand nature as well as instruments, at the same time. Medical devices are simply an advanced understanding that began with understanding electromagnetic waves through Maxwell’s equations.
Each of the following 4 equations has a different name, by which we call’em, but together they are called as the Maxwell’s equations. Together they constitute what I am inspired to say; the golden equations of Physics. If we do some easy tricks they will be converted into whats called as the Wave Equations (of motion) ! Yes, they describe the wave behavior “fully”.
— By that I don’t mean sound waves, but any sort of waves that move at the speed of light. Sound waves are ordinary pressure oscillations, that travel much slower than even rockets.
The 4 equations therefore describe how electromagnetic waves are created and broadcast. Hence TV radio and satellite communication were understood because these 4 equations were understood.
First two are time-independent or static equations.
The first equation is known as Gauss’s law of electrostatics and says “Electric fields (E), are a result of sources of electrostatic charge”.
The 2nd equation is analogous and called as Gauss’s law of static magnetic field. But it says “apparently there are no sources of magneto-static charge or single magnetic pole from which the magnetic field B is created”.
Then how are magnetic fields created? We needed to know further to find the answer. Lets look at the 3rd and 4th equations. More…
What happens when some UV falls on biological molecules? (or any kind) some of these molecules like the wooden pole absorb the energy and there still remains energy which they can emit as visible light. So the UV light kicks the molecules and the molecules in turn emit visible light. This implies that the UV wavelength that the molecules absorbed energy at are very small compared to the wavelength at which they emit visible light. This is always the case.
When we say some materials are fluorescent it means they absorbed higher energy and emitted lower energy radiations of colorful light.
But this has a great deal of application apart from its theoretical interest. More…

OHSO, A Modern Mystic – “My message is not a doctrine, not a philosophy. My message is a certain alchemy, a science of transformation.”
of-course your messages are a science of transformation … called sound wave if it travels by air … its speed is determined by the density of air. And if your message is sent via the satellites; it obeys Maxwell equations among other things … such as Lorentz transformation of em waves.

Just a simple calculation, I did, says; the heaviest meson we know, is 35% lighter, than the water molecule, and about 22000 times heavier than electron. I am thinking along side the PDG list of particles; all atoms and molecules can have their properties mentioned …
A quick division by 0.35 gives that water molecule is therefore, 62.86 K heavier than one electron. Thus the water molecule nucleus is 6.29 K times heavier than the total electrons it has revolving around its nucleus. (There are 2 H and 1 O = 10 electrons right? Or is it 18?)
Simple explanation of OPERA Anomaly of FLT
I just wrote two tweets, one of which, is a concise explanation of OPERA anomaly of Faster than Light neutrinos. (FLT neutrino). Einstein’s Relativity Theory would be invalidated if neutrinos move faster than the photons, which is what OPERA experiment suspected it obtained, but Quantum Mechanics Uncertainty relations would save the grace of Relativity of Einstein, from falling off as an invalid theory. Its a bit tricky, but I explained it in 140 characters.
Here are the tweets.
Heisenberg would have tweeted in 1925:
1. when Q. Mech came physical variables got hats 2wear and were called as operators rather than variables, Heisenberg wanted2 tweet so in 1925.
OPERA anomaly would also be explained by Heisenberg in 1925 via tweeter. Look guys.
2. Q. Mech uncertainty; E=f(t), p=f(x) >> E-t, p-x fuzzy, mixing of variables E-t, p-x, if E-x mix, eg E=f(x), E-v fuzzy, as v=f(x) > OPERA FLT More…
