Euclidean Relativity
July 9,2021

Many texts on relativity often present it in a way that makes it seem unintuitive and difficult to visualize . However, we can easily formulate relativity in terms of ordinary Euclidean geometry.

An easy way to see this is by starting with the Minskowski approach and switching the roles of time and proper time to get $$t^2 = \tau^2 + x^2$$ (using natural units $$c=1$$). This means we now treat proper time as the 4th coordinate rather than common time. This approach is also sometimes referred to as Proper Time Geometry or Circular Function Geometry . ...See More

Hello World This is the test page for the blog.
The following is an equation.
$$R_{\mu\nu} - \frac12 g_{\mu\nu} R = \frac{8\pi G}{c^4} T_{\mu\nu}$$

The following is a TikZ picture:

Regarding the Conventionality of simultaneity
January 4, 2021
the famous assertion by Einstein that the length of a rod depends on its velocity and on the chosen definition of simultaneity. …is based on the fact that we do not measure the length of the rod, but its projection on a system at rest. How the length of the projection depends on the choice of simultaneity can be illustrated by reference to a photograph taken through a focal-plane shutter
