AI Thread Summary
The discussion explores the relationship between the units Kelvin/second and Joule/second, questioning if Kelvin can represent an amount of energy similar to Joules. It highlights Boltzmann's constant as a crucial link between temperature and energy, analogous to how lightspeed connects time and length units. Participants consider the implications of this relationship in thermodynamics and energy transfer. The conversation emphasizes the importance of understanding these connections in physics. Ultimately, the link between temperature and energy is significant for comprehending energy units.

Is there some kind of link between the units Kelvin/second and Joule/second? I'm thinking a value in Kelvin would represent an amount of energy, just as Joule. Or?

Indeed, just as lightspeed is the link between time units and length units, so is Boltzman's constant the link between temperature and energy.
 
Thread 'Gauss' law seems to imply instantaneous electric field propagation'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Thread 'A scenario of non-uniform circular motion'
(All the needed diagrams are posted below) My friend came up with the following scenario. Imagine a fixed point and a perfectly rigid rod of a certain length extending radially outwards from this fixed point(it is attached to the fixed point). To the free end of the fixed rod, an object is present and it is capable of changing it's speed(by thruster say or any convenient method. And ignore any resistance). It starts with a certain speed but say it's speed continuously increases as it goes...
Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
