What could be the mass of the magnetic monopole?

When Dirac introduced his magnetic monopole for explaining the quantization of the electric charge he left the mass as a free parameter of such particles, but nowadays we have many different kind...

Why does appear always two magnetic poles in a magnet and what has created them physically ?

1. Why do we have always a pair number of magnetic poles? 2. What makes the "south pole" S to have a behaviour so different than the "north pole" N if they were made just by "spinors". The spinors...

What is "beauty" in mathematics and theoretical physics?

Mathematics is fundamental in all sciences and mainly in Physics, which has even had many contributions. It seems that the capacity to be applied would be the motor to be create. But this not what...

Are magnetic and electric fields made by different photons?

Quantum field theory tries to reduce the fields to particles (bosons) which interact with their sources (fermions) transferring energy and momentum, if we restrict to electrodynamics. In the case...

Why are there no stable states with more than three or less than two quarks?

It is known that hadrons can be divided in baryons (fermions of three quarks) and mesons (bosons of two quarks). The sum of their electric charge is always an integer number, e.g. the proton is...

What are the most interesting unsolved problems in science for you?

Let me introduce some of mine: 1- Reach quantum gravity for introducing this interaction into the quantum field theory and probably to be unified with the other three...

What is the biggest scientific coincidence that you know?

For me the two more important are: 1. The phase transition liquid-solid for the water is that the solid state is less dense. 2. The dielectric screening in metals is such that the Coulomb...

What has been the biggest scientific injustice, fraud or intellectual illegality that you know?

One of the most known is the cold fusion that Fleischmann and Pons claimed to find in 1989 a chemical reaction at room temperature, which had an implicit nuclear reaction produced at tens of...

What is the difference between fundamental particles, dressed particles, quasi-particles and collective excitations?

The question is how is it possible to distinguish one electron forming a Cooper pair in the superconducting phase or the composite fermions having anyonic statistic behaviour in the Fractional...

What is a physical theory, a creation or a discovery?

It may seem that Einstein could create wonderful theories without going to any laboratory as Newton or Maxwell just by using their minds. Might this be possible overall nowadays with the huge...

Do you know what is the best thermoelectric material?

The figure of merit measures the capacity to transform thermic energy into electric energy and there are many materials with a high Seebeck effect which nowadays are lower than three (adimensional...

Can anyone help with Lorentz tensors?

I have sent one question about the Lorentz transformation of M and P without explaining enough the reason of doing it. Therefore let me to come back to such question made in more accurate physical...
