The Engineer’s Faith

Engineering and faith might not be two words you normally associate, but faith is nevertheless an integral part of our profession. What tends to obscure this relationship for many today is the rather antagonistic definition of faith promoted by atheists as “belief in spite of the evidence.” Certainly, that is the last characteristic you’d want in the engineer designing your new home/office/hospital/school/etc. But as I’ve written extensively on this site (here especially), that is not the biblical definition of faith. Biblical faith is rather a warranted trust, or looking at the Greek root for the word, a divine persuasion. Let’s look at a scenario that exemplifies the correlation between biblical faith and “engineering faith”.

Suppose I told a client that an existing column in a building being renovated would need to be reinforced or replaced, at significant cost, or else it would fail under the new loads the owner wanted to add. Now suppose the owner didn’t like this and wanted to argue about whether this was really necessary (yes, this does happen). He could ask whether I’d ever actually seen a column that big fail. Or, supposing that part of the issue was tied to increased seismic loads on the existing structure caused by this new addition, he might ask if I’d ever experienced an earthquake, because he had, and it wasn’t that bad… In both cases, I’d have to answer “no”. So what is my basis for saying he needs to perhaps double the cost of his renovation? My trusted engineering books. Here’s why:

  • I trust the authors. While I’ve never personally seen a large column fail, I don’t have to have personally seen it to know it can truly happen. Various people over the years have performed tests, witnessed the results, and applied reason and logic to sift through the noise and ascertain the essence of different phenomena. Then they distilled all of that down into some of the elegantly simple theories we still use today. They have demonstrated themselves to be trustworthy with their meticulous attention to detail, their investigative diligence, and their relentless pursuit of the truth about how structures behave.
  • I trust their records. These early pioneers and those coming after them have written down very detailed accounts of these tests, their results, and their reasoning for how far their theories can be expected to be applicable to similar conditions. These have been preserved (or at least copies have been) for future generations of inquisitive engineers like myself. Names like Euler and Timoshenko still cast their shadows on much of our work long after they died.
  • I trust the transmittal of their works. Our engineering textbooks and reference books faithfully transmit these principles to my generation of engineers, even though we are far removed from the original authors, and may not have the resources to reproduce their findings. Their theories are also reproduced in a variety of books. If one publisher made an error in Euler’s column buckling formula, for instance, it could be readily verified by comparing it against other reference books on the same topic.

So then, even though I have never personally witnessed a W14x90 column fail in an earthquake, I can trust that my various books have reliably passed down to me the true results of research by trustworthy men indicating that would be the outcome in my example. The end result being that I can put some amount of faith – or trust – in what I’ve learned and apply it to the current project. Of course, men are still fallible, and their theories might be mistaken, but these basic principles are have stood the test of time sufficiently to persuade me to trust them.

Now, how does that relate to my Christian faith?

  • I can trust the biblical authors. God used a unique mix of people to write the Bible. Just looking at the New Testament, the first apostles were simple fishermen, who brought a simple, down-to-earth, eyewitness testimony to their records. Theirs was a record that said, “whether you believe me or not, I cannot tell otherwise, for this is what I saw, and heard, and felt – no more, no less.” Luke was a doctor who sought to record “a more orderly account” of the life of Christ. His account is an extremely detailed, first-rate history that has proven itself accurate over and over again. Paul was a Pharisee, a teacher of the Jewish religious law, himself taught by one of the leading teachers of his day. He explained the deep richness of the simple gospel message, connecting it to the whole backstory of the Old Testament. But in each case, these men have shown themselves to be trustworthy instruments of the infallible God.
  • I can trust their findings. Luke’s geography and description of various cultures of the time are born out by archeology. When Paul describes the fallen nature of mankind, he describes the world I observe; the results of his examination match reality. But moreover, he holds up a mirror to my own heart. I need look no further than my own life to recognize the soundness of his words.
  • I can trust the transmission of their records to me. They wrote early after the events they described, these writings were copied carefully, and on a massive scale far exceeding any other historical manuscripts, such that the integrity of their writings are adequately preserved by comparison of the variances between dispersed copies.

We all place our faith (or trust) in people and things that may prove all too fallible: the pilot of the plane you’re about to board, the engineer who designed the school you send your kids to, the political leader that promised you the moon, or objects as simple as the new tires on your car that you trust to not have a blowout.  But there’s really only One who warrants our complete trust. Have you studied His textbook, the Bible?
