The movie ``The time machine" IMBD link features
some black and green boards with mathematical formulas.
MOV, OggWebm.
Some of the formulas are a bit strange.
What does 4'' mean on this frame. It might not be a 4 but a psi.
On this frame one can see the gradient of a potential phi as well as
a magnetic flux and something which looks like the divergence theorem. One can also make up a
Maxwell equation for the curl of E.
There is an elliptic integral on
this frame, where lambda is both integrated over
as well as is in the lower bound. Tr{ W2 } probably means trace.
The 8 π T appears in the Einstein Field equations. The ∇2 A in the
wave equation for the electro magnetic potential A.
