Topics, issues, ideas, and memes in Einstein's theories of relativity. We develop our problematics in an incremental, evolutionary fashion. We plan to use this web page to develop memes which apparently put Einstein's relativity theories in question. Indeed our work here puts physics' use of formal mathematics in question.
None are definable.
Einstein's theories of relativity depend on an assumption that certain physical conditional identities exist . Here, we see that a concept of physical identity depends further upon a concept of objective reducibility. Indeed, a concept of identity insinuates a legion of other objective concepts, e.g., analyticity, homogeneity, independence, et al. Figure 1, above shows an equal sign forming an identity twixt left side of 'equation' and right side of equation. 1 produces zero.
