In this video, I explain Modified Unit Analysis (MUA) to Chantal Roth from first principles. Chantal had no previous experience with MUA and therefore she had no preconceived idea of what it was all about. The purpose of this exercise was to explain it to her in the best way that I could think of and to get her honest first impression of MUA. I personally think it went very well.

![Robotic Arm: Kinematics using 2x2 Matrix Version of Eulers Formula
Here is a short video I made of the software I am working on that uses the 2x2 matrix version of Eulers formula to help solve the kinematics of the mechatronic arm that we are using in one of our medical devices. Each joint of the arm uses one 2x2 matrix to track the rotations:
[+cos(t) +sin(t)]
[-sin(t) +cos(t)]
This is really cool and I am very proud of my work. Robotic Arm: Kinematics using 2x2 Matrix Version of Eulers Formula](https://i.ytimg.com/vi/nQHKDj4Q93Y/mqdefault.jpg)



![On the Radius (and the Fine Structure Constant)
In Modified Unit Analysis, the units of RADIUS is [m/rad]. In this video, I explain why. What does the fine structure constant have to do with this? I guess you will have to watch and see. On the Radius (and the Fine Structure Constant)](https://i.ytimg.com/vi/oFqLzcx0vAo/mqdefault.jpg)
