### Control Theory

September 26, 2018

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.

### Sword cutting… and how the target pushes back!

September 19, 2018

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?

### What Does Hitting Hard Mean?

September 5, 2018

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’.

### How Fast Do Swords Move? – Try 1

August 22, 2018

My first attempt at motion capture. It wasn’t great, but I got something. And you can all laugh and learn from my mistakes.

### Introduction to Material Properties

August 8, 2018

When understanding equipment it’s important to have a basic understanding of material properties, and — most importantly — how they interact.

### Force Vector: More than a science-ey sounding name

July 25, 2018

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.

### What is Force Dispersion? And how it keeps you safe from swords.

June 27, 2018

How our gear keeps us safe is an important topic, especially if we ever want to make it safer!

### Impact, Impulse, and Momentum

June 20, 2018

Sometimes people talk about how much ‘force’ something hits with. Unfortunately, they use the same term to describe average force, peak force, and impulse.

### The Myth of Control

June 6, 2018

Why going at high intensity and having perfect control is not physically possible, no matter how much we want it to be.

### Hanging Targets is cheating!

May 30, 2018

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.
