Physicology is a method of understanding and teaching movement which Jos has been developing for several years.
It looks at dance technique from the fundamental physics of that govern all movement, using experimentation and analysis all the way through to complex dance material and movement creation.
Starting from the way in which body connects to the floor and how to gain a deeper understanding of that push; the method grows to cover centre of mass, stable and unstable positions, momentum, force vectors, circumferential forces and the lines of connection that pass through the body.
Simultaneously it works with the idea that psychology and imagery are deeply linked to the way bodies work, that performativity and technique are not separate things and should be looked at in parallel throughout the training process. The class builds all of these elements from simple experiments and demonstrations through to challenging phrases that incorporate the themes of the class and applies them into both minimalist and more acrobatic movement. With the aim of allowing dancers and other physical people not only to learn new movement but to have a deeper understanding of how it works.
This section is for anyone who has studied some Physicology who wish to see more about the physical rules that underpin it.
Newton’s laws of Motion
This is the foundation of Physicology and on some level it all comes back to these three rules. These rules govern all movement as long as you are not microscopically small, the size of a planet or travelling at close to the speed of light.
|I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.|
|II. The relationship between an object’s mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.|
|III. For every action there is an equal and opposite reaction.|
A brief look at the physics of cornering and the importance of grip

Cat flipping physics
Looks at conservation of angular momentum and the way that accelerations in one part of the body causes counter-acceleration in another

A demonstration of moving ones base in order to get a force vector that allows for cornering.
More reading on force vectors, relevant to how one can push into the floor at angles to make the body accelerate.
This is just really interesting rocket science from the wonderful channel SmarterEveryDay. It has a tangental link to spins and pirouettes in terms of circumferential forces and the conservation of angular momentum.
A longer film which gives an interesting look at how understanding of counterbalance angles changed architecture, which has an interesting relationship to partnering work and back bends.
The centre of mass on a body
Demonstrating that it could lie outside of the body, the image of the gymnast shows this perfectly.
The difference between centre of mass and centre of gravity
Whilst for the purposes of a dancer in a studio they amount to the same thing, it is interesting to know the difference between the two.
Archimedes on the power of levers:
“Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.“
