Recently I have read some non-technical publication and books on strings (ex. The elegant universe by B. Greene). Greene says that the string theory unifies all interactions and explains their nature. In fact I haven’t found any explanation why do particles / strings interact. I mean – why do...

Re value of c. Many of you point out Maxwell, and that means we talk about permittivity and permeability of the space. If this space has certain properties can we call it empty space or vacuum? If the empty space is really empty should it have any properties at all?

And the 2nd question: Do we know why is the speed of light 3*10^8 m/s? What determines this value? (I'm not asking about system of units) S.

Thank you very much for the explanation Amr Morsi…. but unfortunately I’m not so easy to satisfy ;) I understand that QM speaks about probabilities and not forces. And, if I understand your post well, the result of interaction between 2 particles, computed with QM, is the probability of...

In textbooks I’ve read that the Coulomb’s force law is accurate up to 10^-12 m. Below this limit the force between charged particles should rather be calculated according to QED. But I’ve found no answer what are in fact the differences… So, are the electromagnetic forces between charged...

Is mass spectrometry the only technique used to measure the mass of charged particles? In other words is it possible to measure the mass directly or is the measurement of mass-to-charge ratio the only way to get the mass? S.

So what is magnetism than? I thought that magnetic efects come from changes of charges magnitudes as observed in different frames... I can not agree with the argument of your professor - the moving neutral object consists of both + and - charges, so if both move with the same velocities with...

Yes, I do :) Thank you Lightarrow

Can someone help me to calculate the difference between accelerations due to Newton’s law of gravitation and Einstein’s general relativity? Let’s assume the gravitating mass M equals to 1kg and the distance r equals to 1m than the acceleration due to Newton is: a = G * M / r^2 = 6,6742...

If this is true, than the oscillator working on the frequency ½ Hz can’t emit the radiation. Or am I wrong?

Thanks. I do understand although I don’t get the point, I think…. Following your post – if the Planck mass gives the Planck length, so the electron’s mass should give the electron's length which should be about 10^-58m. Am I right?

While the other basic Planck’s units i.e. length and time are extremely small in comparison to elementary particles (length is about 10^-35m and time is about 10^-44s) the Planck’s mass is about 10^-8 kg! As we can see the Planck’s length is about 10^20 times smaller than are the dimensions...

Thank you. I thought before that the energy must be procuct of integer number of 'h'.

According to quantum mechanics the energy of radiation is equal to multiple Planck's constant : E = h * v, where "v" is the radiation frequency. Since there is no limit to frequency, what is the energy of radiation of frequency 1/2 Hz? S.

Hi and hallo to all enthusiasts of Euclidean Relativity. I’ve read the whole post and some papers of some of you – those of Rob and Jose. Although I don’t understand some of your thesis and ideas I’m an enthusiastic supporter of the ER concept. Studding the geometry based on the equation...
