Fun story: One of the first things I was taught as an astronomy student is that, if you want to be a dick to someone giving a presentation, ask them “and how do the magnetic fields play into this?” and they will invariably say “fuck you I don’t know” because no one understands magnetic fields they are black magic.
Derby was born with deformed front legs. His humans bought him a cart, like a wheelchair for his front, but it limited his mobility. The owner decided on something kind of like the “running man,” which look like blades, but those might get caught in soft ground.
3D systems designed these loops just for Derby, and he is now able to walk, run, play with other dogs, and do virtually anything a typical dog would do.
