Now imagine that you recorded the which way path as far as you were concerned only to realize that your mechanism wasn't functioning. What would be th ...Read More

Suppose an object of mass m is released from a height h bounces off the ground and returns to a height h' (h'< h). The object experiences a force at t ...Read More

The farther away one is from the explosion, the larger the hemisphere of he shock wave is, and so the more the energy from the explosion is dissipated ...Read More

the component of angular velocity with no angular momentum) goes as $ω ~ (GM/Rc²)(v/R)$, which is 1st order in $v/c$. However, I read in Zee's "Einste ...Read More

My first thought was to segment an arbitrary path $R=R(t)$ from $A=R(0)$ to $B=R(1)$ into $N$ pieces and construct a "spherical" sequence of paths $P= ...Read More

Quantum tunneling is a quantum mechanical, and not a classical phenomenon, where the wavefunction of an object can spread across a potential barrier. ...Read More

As I understand it given a pseudo-Riemannian spacetime manifold $M$ we can consider the group of spactime transformations $G$ which act transitively o ...Read More

Postulate IV. Postulate III. Callen introduces entropy by the following four postulates: Postulate I. Postulate II. Postulate IV implies that $S$ has ...Read More

can you compute the two point function for a scalar field?) What gauge are you working in? Anyway this calculation is done many places, an example is ...Read More

I'm not sure what to call those variables since I couldn't vary them, which means it's not an independent variable. If that is not the case then you m ...Read More
