SMTP

It is often useful and helpful to simplify things that are quite complex, both for utility’s sake and to allow some semblance of meaningful interaction with the average person - and for that case, the vast majority of people. One could go into all of the complicated and sticky math and calculus involved in advanced differentiation, but simply conveying the concept of “the area under the curve” is helpful - and complicated - enough for most. One could go into thermodynamics, and combustion techniques, and how many joules are in a kilocalorie (and for that matter how Joules are even calculated) but simply conveying the number of ‘calories’ in your snack sized portion of cookies on the back of the label is useful enough for - at least for the average person to understand how many extra laps around the block they need to walk the dog to work off the cookies. One could go into carbon compression, crystalline structure formation on the molecular level, and spectral filtration of light based on geometric shapes and angles, but telling the average bride-to-be that it’s a “princess cut” is good enough; more information might even confuse, or worse, inhibit the sell. One could go into the complexities of server exchange, client authentication, cloud transfers, and the like, but using the term “Simple Mail Transfer Protocol” is probably better. Similarly, one could go into the complexities of sotierology, unconditional election, atonement, and topics like supralapsarianism, divine foreknowledge, and the like, but probably the most helpful and useful thing someone could say regarding the topic of salvation would be “Repent and believe the gospel” (Mark 1:15)
