In a way, you can tell what kind of educational or vocational background writers have, since they very often build on that or very much indulge in their passion. For example, it would be no surprise to anyone that Tolkien was a linguist. Umberto Eco poured his whole academic background into The Name of The Rose (one of the most amazing things about it was the author's detailed comment on why the whole plot needed to take place exactly there and then due to historical reasons, how he needed to design the library to make the fire possible etc.).

Mark Stanley is a nuclear engineer (as far as I recall). For better or for worse he likes to delve into details about physics, machines and all things related. At the very least I can say he introduces all those pieces of information in a way that works with the characters. The question about radiation would be very much something Sam would ask given the situation and we got actual interaction between him and Florence instead of a dry infodump. Microgravity movement lessons were really fun actually and it is also nice to see that Sam got the hang of it as can be seen in recent strips.

It might be boring for some people, but done right knowledge sharing can be really fun.
