The title appears simple and far-fetched and runs contrary to common sense. Nevertheless, it is overly stated and overly simplified, although it does hide the true physical meaning, which cannot be described by current mathematical equation using vector analysis or tensor analysis or spinor analysis or even quaternion analysis or twistor analysis.

In order for time to be equivalent to magnetism, the force of gravity must vanish, then using the second permutation of Lorentz force, the electric field intensity vector becomes equal to the vector product of the velocity vector and the magnetic field intensity vector, . Taking the absolute values of both sides gives then dividing by |B| gives |V|\sin \phi =\frac{|E|}{|B|}[/math]. If is 90 degrees then . However, [math]|V|=\frac {|L|}{|time|}. Therefore, by direct correspondence, length (L) is equivalent to electricity and time is equivalent to magnetism.

Antonio,

I wonder why the formulas didn't come out this time?

Anyway, when you say "x is equivalent to y" then you mean that the size of the measurmenet of x will be equal to the size of the measurement of y, right? Because that is it's mathematicla meaning. But if what you mean is that if there is x there y and viceversa, then you might say it "if an only if x then y" which means x<-->y if there is one, there is the other. Or do you mean another thing apart from these two?

Work best by sending you another email pdf file. Their units are comparable in angular measurements such degrees and radians.

I forgot what "degree" and "radian" meant in maths, can you summarize it?

What is physically a radian?

Is it the relationship between the circumference and the degrees?

A diagram would help.

Radian is an angle, it implies rotation in 2 dimensional space from a vector to another. A dihedral angle is a planar angle of solid spherical geometry implies a perfect sphere with one center and great circles or longitude circles and small circles or latitude circles. I must go to work now.. continue later.

Does it only impply rotation, or can/does it also impply reflection, translation, enlargement....etz?

If it doesn't, is there any other thing like radians are for rotation, but to the other transformations?

Rotation is a special type of continuous transformation. Besides the angles between lines and angles between planes there are also solid angles measured in staradians. A sphere would have 4pi staradians.

But is there any such thing as radian is to rotation, but something is to another transalation? Is there a something like that for reflection, or translation, or enlargement, etz???
