I have to say. I enjoy reading them.

To spice things up. If scientists, or should I say, theoreticians didn't come up with theories, do you think engineers would even engineer something(?) or rather, would engineering even exist in the 1st place? You would probably argue and say that those are just regular theories and not scientific theories--for instance, gravity is a scientific theory tho we can say its just a regular theory just because we experience/see it every day, but no one really figures it out, until Newton had scientifically proven it. The same goes for everything in engineering. True, every theory that is associated with what they're engineering doesn't have to be exactly as what the theories said, but they use it anyway. Why? They tweak their works most of the time because they can, or should I say, these theories let them do so, not because the theories are proven to be wrong, BUT those theories provide these so-called "formulae"--that depending on the given situation will provide different results OR the answers that they needed. In fact, what we use right now are just temporary laws/facts, it is subject to change and depending on the circumstances, other theories might actually finally be proven and other laws might be completely abolished.
