How can a string the size of the Planck length (10^-35 m) have a wavelength of the speed of light in meters (10^8 m)?

A serious question, if the minimum length of a single quanta (where n =1) is the Planck length; and the maximum wavelength, from E=hf (where f=1), is the speed of light in meters, then how are...

Is the magentism in electromgnetism (photons) generated by the motion of the electric field?

It is generally thought (see Special Relativity, A. P. French) that the magnetism we detect form an electric field, is related to relative motion with respect to that field. Specifiically a moving...

Do clocks run at diffrenet speeds at difrrent latitudes , as according to STR?

Diffrent latitudes on Earth have different velocities relative to each other. This is because the velocity is less at other parallel latitudes than at the equator. Have experiments confirmed this...

What is the mechanism an electron can appear to gain relativistic mass in conventional SR?

In conventional textbook SR the mass of an object with rest mass m0, increases its relativistic mass m' by the formula m' = m0. sqrt(1-v^2/c^2). What is the proposed mechanism for this increase...

What is the closest experimental value we have for the radius of the free electron?

The classical electron radius is well known and effectively represents the charge radius which is 2.82 X 10^-15 m. The "physical" radius of the free electron has yet to be determined...

What is the speed of the electron spin assuming the classical spin model of the electron?

The spin of the the electron is known as h/2. We are told that this is not the classical spin primarily because the speed of the electron would need to far exceed the speed of light. What is the...

What is the significance of the term h.c^4 or more specifically the term 8pi.h.c^4.alpha in relation to the electron?

In the study of the electron the term h.c^4, or more specifically the exact term 8pi.h.c^4.alpha seems to have a special significance. The question is what (dimensionally or otherwise) do either...

Discrete Phase model (DPM) particle break-up has particle size limits during particle tracking?

Hello, I am currently working on simulating water droplet partciles in a closed room. When I use uniform particles, without "particle break-up", I can carry out the simulation without any problem....

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
