Minkowski Definition and 206 Threads

draw a minkowski space-time diagram for s and s' showing x- and ctaxis as well ass the x'- and ct'-axis. the x-axis and ct axis will span from 0-5m. everwhere x'-axis ct'=0 and likewise for ct'-axis x'=0. [(v=0.6c)(t=t'=0, x=x'=0)] so any way I start out with drawing ct and x. like a normal...

Please help me in any way you can. I'm a beginner physics student (entering undergraduate engineering) and currently self-taught. 1.) Minkowski space is illustrated in one of my books as a cone, with it's apex as the "origin", the side as the "light cone", the bend curvature inside the cone...

Why does everyone use +---/-+++ Minkowski spacetime over ++++ Euclidean spacetime? Minkowski spacetime preserves spacetime intervals under Lorentz transformations but so does Euclidean spacetime under equivalent rotational transformations from which SR can also be deduced. (someone show me how...

Maybe this is really easy, but... Can someone show me how the sign reversal between the space and time components of Minkowski spacetime make its intervals Lorentz invariant (mathematical derivation) ? Thanks... :wink:

Electromagnetism being mediated by space-time rather than particles or waves is based on the validity of the Minkowski space-time metric. Energy held by a quantum object A at an event 1 can jump to a quantum object B at an event 2 provided the proper interval separating the two events has...

I've just been thinking (prolly a bad idea): Lorentzian metrics aren't actually metrics at all are they? In fact they're not even pseudometrics, so what are they exactly and why do we call them metrics (Actually I can probably guess that as they perform the same role a mteric does and they are...
