How do particle acquire thermal distribution?
Consider some toy N-body simulation: we start with a bunch of particles, discretize time, and simulate their interactions at each timestep. What numerical features should the simulation include to ...

Chemical equilibrium for distinguishable reactant particles
Denote the partition function of a single particle by $\zeta$. The particles of one type of reactant in a chemical reaction are normally indistinguishable. The partition function of $n$ number of a ...

When calculating Lagrange points, $L_3$, $L_4$ and $L_5$ are good, but why are my $L_1$ and $L_2$ too close to the Earth?
I'm using python to calculate the Lagrange points of the Sun-Earth system. I started assuming that - for $L_1$ at least - the sum of the gravitational acceleration towards the Sun and the centripetal ...

Is bouncing ball (100% collision) an oscillatory motion/SHM or both or none?
My teacher told me bouncing ball (100% elastic) is oscillatory motion that does not have a stable equilibrium position and restoring force. It is just to and fro motion and thus called oscillatory ...

Can a body be in thermal equilibrium at a different temperature from surroundings?
As per my knowledge bodies attain constant temperature (thermal equilibrium with surroundings) when they absorb and emit energy at equal rates.
Let us say temperature of surroundings is T1.
We have a ...

How are curved soap films stable?
How do curved soap films remain in equilibrium, if surface tension tries to pull them taut?
What I understand:
Surface tension acts tangentially on a surface.
The potential is energy is proportional ...
