"Almost" Theorems
- If a function has a value at a location, on a device such as a calculator, then it has a derivative at that point.
Exception: arcsin(1)
- The general solution of an nth order ordinary differential equation is a family of functions depending on n independent arbitrary constants.
- The general solution of an nth order partial differential equation in m independent variables is a family of functions depending on n independent arbitrary functions of m - 1 variables.
- A definite description (as defined by Bertrand Russell in Principia Mathematica) always functions (refers) as would a name.
- A class (as defined by Bertrand Russell in Principia Mathematica) always functions as if it were an object (set).
- Objects that are not fully analyzed can always be treated as (simple) objects in logic.
- An physical object in Newtonian physics can be considered a point particle located at the object's center of gravity.
- All prime numbers are odd.
- One should search for "minutes" when wanting to find information on a meeting.
- Unless there is something to contrast a term or sentence to ("the Contrast Theory of Meaning"), the term or sentence has no meaning. (This was Ludwig Wittgenstein's big mistake.)
