Begin discussing materiality of strings
Think of a worm made of strings
A space time worm that leaves a space trace
Each string is a loop that is a time point
Fused loops
Loops are like rubber bands not chains
Imagine colour gradation of loops into past and future away from current time point loop
Space time is 10 dimensional
We only see 4 dimensions
The other 6 are curled in the ‘inner space’ as a manifold which is too small to see
Alessio and group just study the inner space
They think of the 6 dimensions as 3 larger dimensions and 3 tiny ones
The larger 3 dimensions are the faces of the polytope
The smaller 3 dimensions are a 3d taurus and this is where the strings are/live
The strings are 1 dimensional loops ‘painted’ on this 3d taurus
The tiny strings can move between the larger 3d spaces (faces of polytope) by connecting to space time worm of other 3d space, at the boundary where 2 3d spaces meet in 4d space

In the middle of the faces of the polytope there is a grid
A wavy grid
A wavy, sense of quantum, wavy grid
Inside the grid are worms within worms showing process of strings
On the face of the polytope
Inside the donut (how do we see/imagine/draw a 3d donut?)
