In Episode 8, we will explore what it means for Tau to be a function and how Einstein’s mistreatment of Tau as an equation has resulted in the math problems contained in his derivation. This episode will explore four areas. First it will explore functions, clearly identifying the proper way of defining and using functions. Second, it will explain some of the pitfalls of mistreating a function as an equation. Third it will explain how Xi and Tau are correctly derived when Tau is treated as a function. And fourth, it will revisit Einstein’s derivation to illustrate how his mistreatment of Tau as an equation results in the math problems previously discussed in Episode 2 and in the Storrs presentation.
