Many years ago, on a very old version of the Webel site, I had up a quick attempt at mapping out the families of physics particles in SysML. Although I have a PhD in physics (astrophysics), and had even worked at the DESY particle accelerator institute (on data analysis, and modelling and operating the machines, not particle physics), I am not an expert in particle physics.
I had a mistake in the classification of one of the lesser known (to me) particles. Someone who knew far more about it wrote to me and told me it was wrong. I took those examples down, then some years later I made a new one about the particle families (using Webel Parsing Analysis against Wikipedia articles) to demonstrate (amongst other things) use of Block inheritance to model systems.
I've also sometimes had some minor mistakes in use of Activities in basic UML (I wasn't involved with the creation of the early UML language), and colleagues who were involved with the UML language specification and knew more about it corrected me.
Putting yourself out there with SysML diagrams in public, in resumes or job applications, or in meetings and presentations to colleagues, invites correction. The people who are brave enough to do so invite more help and improvement, they are the MBSE heroes, even if their initial attempts are not perfect, and their fixes flow through the entire model and all diagrams.
Here's the improved particle model as a tutorial slide. Even then, classifying some of the more exotic particles was tricky, but at least the attempt communicates to others to invite correction and improvement, and demonstrates use of aspects of SysML.
