Well I think that time is like other three dimensions in this regard. Simply that mass is moving through time so there is nothing in the past (or future).
So if I understand it correctly unitary charge is either constant or we would detect changes in fine structure constant, thus we could assume that unitary charge is constant whaterver charge actually is?
I was trying to think about charge and I am curious. It seems that there is unitary charge - +1 for protons and -1 for electrons. But is it possible to say that it is constant in time? I mean would it be possible to detect changes in unitary charge value? size?
Let us say that all charges are...
I am definitely no expert so I might be wrong, but I would say that the length would be
\left|AB\right|=\sqrt{(a_{w}-b_{w})^{2}+(a_{x}-b_{x})^{2}+(a_{y}-b_{y})^{2}+(a_{z}-b_{z})^{2}}
First, I am sorry for very unspecific topic, but I really have no clue what I am looking for. I need some way how in mathematical terms describe things like following:
I have line segment of length l and I have sine function with period length \lambda originating at one end of line segment. If...
I think I am staring understand this. It does make sense. But if I am looking at planar wavefront frozen in time - all E field vectors would have same direction (magnitutde may vary) regardless if this is polarized light or not. I would be able to tell the difference only if I follow the...
Well I also know very little about liquid mirrors, but what I found about Galinstan it is really sticky and adhere to almost anything. To prevent it the surface has to be treated with gallium oxide (maybe there other treatments, but i do not know).
About that scum - From what i have seen it...
So then the classical picture of electromagnetic radiation is just depiction of vector of electric/magnetic field along line going through wavefront, right?
But one more question in case of wavefront (lets say its plane) are vectors of electric field equal at all points of the wavefront at...
I can understand light polarization if light wave is represented beam like as on that wiki page. But how this could go together with diffraction? I can understand diffraction if the light waves are like spheres or planes (as on the blue pictures on this page...
I know those nice pictures showing light polarization, but the light wave should be three dimensional, so no up and down just more and less, like expanding spheres with different desities, right? So it would be more like soud wave, but then the I should be able to detect oscilations but should...
I think that physics could get to this point of knowing "everything" and maybe math. Maybe. However in chemistry, biology and history (just to name few) it is not possible to get to this point, because unlike in physics you do not look for basic laws that govern the universe, but their actual...
I would say that your view would be no different from any point of the universe. I do not know why you should see something differet as far as i understand physics.
