KX21 can't do even the simplest math

In Reply to: M Physics 21: SR's E= SQRT(p^2c^2+ m^2c^4) is an ill-defined function, with more formal Mathematical proof posted by kx21 on May 07, 2003 at 19:47:34:

1) E = sqrt( p^2c^2 + m^2c^4) is a discrete function-
E=f(m, p)) &

It's not discrete but continuous for p =0, m =0. The square root function is defined and continuous for those values.

2) the Equation is not a well defined function in the eye of Mathematics...

FALSE. As I will show.

Given SR:-

E = sqrt( p^2c^2 + m^2c^4)

iff

Here's the problem. There is no justification for "if and only if" (which is what iff means). If would imply that the function f is only defined for the following two cases. NOT SO! F(m,p) = sqrt( p^2c^2 + m^2c^4) is defined for ALL non-negative values of m and p. For p = 0 and m = 0.

E=mc^2 (m 0 & p = 0) and

E=pc (m = 0 & p 0).

These are the two limiting cases, where either p or m is zero.


Let E = f(m, p), where

f(m,p)

=mc^2 (m 0 & p = 0)

=pc (m = 0 & p 0)

= '?' ( m 0 & p 0)

What is '?':- The 'Black Hole' in SR's Space.

Kx21's f(m,p) is only defined at p=0 or m=0, and says nothing about the true F(m,p) = sqrt( p^2c^2 + m^2c^4) . You can't prove one function is undefined by talking about some other one.

This completes the Proof of both 1) & 2).

This shows Kx21's utter bankruptcy in math, but the energy law in SR is triumphant.
