Can Joule's First Law of Thermodynamics be Applied to Atomic Charges?
James Joule established that all forms of energy were basically the same and interchangeable. My question is if thas law is relevant in particle physics. Can a positive charge and a negative charge be ...

Origin of electric charge
Baryons have charges that are the result of a polynomial calculation of their building blocks (quarks)'s fractional charges. But what gives these quarks electric charges? What interactions do they ...

Will a gas keep forever in a “perfect” flask?
I've been wondering about the porosity of materials, I know that, for example the air comes out of tires/balloons because (besides having huge gaps on the rim contact area/knot) they are made of a ...

How are forces related to decays?
How are decays related to forces, what is meant by particle X decays through the, say, strong force?
The way I understand forces is by how they change the acceleration of particles with the right ...

Is There Any Difference Between Strong Quarks Force and Strong Nuclear Force?
the spectrum of quarkonium and the comparison with positronium potential for the strong force is:
$V(r) = - \frac{4}{3} \frac{\alpha_s(r) \hbar c}{r} + kr$
(where the constant $k$ determines the ...

Inverse square law in 2+1 dimensional universe from a Yukawa coupling?
There is a nice result that in 3+1 space time, a Yukawa coupling leads to an inverse square law force as the mass of the scalar field goes to zero. I was wondering what the corresponding force in a ...

How does gravity force get transmitted?
How does gravity force get transmitted?
It is not transmitted by particles I guess. Because if it was, then its propagation speed would be limited by the speed of light. If it is not transmitted by ...

How are fundamental forces transmitted?
How are the fundamental forces transmitted? In particular I wonder, are all "processes" local, i.e. without superluminal distant interactions? But if they are local, then particles would have to ...

Is there an equation for the strong nuclear force?
The equation describing the force due to gravity is $$F = G \frac{m_1 m_2}{r^2}.$$ Similarly the force due to the electrostatic force is $$F = k \frac{q_1 q_2}{r^2}.$$
Is there a similar equation ...

Paramagnetism what about Paraweakism or Parastrongism?
Ok, I was just curious but the electromagnetic force can allow paramagnetism macroscopically in some objects. Can this be done microscopically to the subatomic level? Also, what about other forces ...

Why isn't Higgs coupling considered a fifth fundamental force?
When I first learned about the four fundamental forces of nature, I assumed that they were just the only four kind of interactions there were. But after learning a little field theory, there are many ...
