Eric has suggested that the wall should be modified to better fit the needs of the Graph, Wall, Tome Project. There are many extraneous items, for instance the Babylonian calculation of the square root of two and the Archimedes cylinder, there are some redundant items such as the Yang-Mills equations and the Maxwell equations, and the placement of equations on the wall doesn't reflect the groupings of the principles they embody. The Wall should reflect and expand the organization of ideas in the Graph.

## Original Wall[edit]

## New Wall[edit]

## Modification Ideas[edit]

What should be in and what should be out of the future wall?
