Strength (mathematical logic)

The relative strength of two systems of formal logic can be defined via model theory. Specifically, a logic is said to be as strong as a logic if every elementary class in is an elementary class in . (Wikipedia).

The hardest concept in Calculus? #SoME2

The ε-δ definition of limits is infamous among calculus students for being confusing to understand and cumbersome to use. In this video I show what is the geometrical interpretation of that definition and give an example of how it is actually used in practice connecting the steps of the re
