You don’t have to understand crazy math with imaginary numbers to appreciate the principles of control theory. They can be applied to sword fighting, and might give you a different perspective on your training or interpretations.
When cutting, the sword exerts force on the target, and the target exerts force right back on the sword. This force is what causes cuts to be less effective, and possibly fail. And where does it come from?
From a physics point of view hitting ‘hard’ can be a somewhat difficult property to quantify. Learn a little bit about what can make a strike ‘hard’.
My first attempt at motion capture. It wasn’t great, but I got something. And you can all laugh and learn from my mistakes.
When understanding equipment it’s important to have a basic understanding of material properties, and — most importantly — how they interact.
I’m guessing most probably don’t care too much about what the difference between a vector and a scalar is. Trust me, it can be a helpful tool for learning to beat people up.
How our gear keeps us safe is an important topic, especially if we ever want to make it safer!
Sometimes people talk about how much ‘force’ something hits with. Unfortunately, they use the same term to describe average force, peak force, and impulse.
Why going at high intensity and having perfect control is not physically possible, no matter how much we want it to be.
Hanging targets for test cutting doesn’t give any sort of realistic impression of what a sword would actually do. Take my word for it, or read to find out why.
