Einstein had similar motives at the start of the 20 th century, when it lacked an organic place for gravitation. This lack of unity is what, in part, fueled his obsessive search for a general theory display that, then the theory needed to be changed. This is what which space itself curved. Hermann Weyl was a student of the mathematician and philosopher Edmund Husserl and went on to become an important Recall that, with the general theory of relativity, Einstein had transformed gravitation from being a force between two bodies into the interaction of mass and energy with the underlying space. Space became malleable, curving and bending based on the distribution of stuff in it and dictating to that stuff how it would move. The way to determine how much space curves is to compare the orientation of unit vectors. A is an arrow and a is an arrow that is one unit long. Place the arrow at a spot in the space so that it is pointing straight up according to someone who is standing at that spot in space. Allow the arrow to move around the space such that an points straight up according to the observer. If we were on a sphere and starting at the North Pole, the arrow would be pointing straight up as we normally think of it. 84
But as we move away from the pole, the arrow would turn because “straight up” changes for people at different points. We can determine the amount of curvature in a space by looking at the angle between the arrow’s directions at different places. direction. If we compare the angle at different points to tell us about tells us about the gravitational effects, and the change in size tells us with a single metaphysical element underlying our observations. Just like James Clerk Maxwell in the 19 th century, theorists in the mid-20 th century were trying to unify forces. Sheldon Glashow, Steven Weinberg, and Abdus Salam were able to do this in 1967, when they showed that the electromagnetic force and the weak nuclear force were different instances of the same thing. Recall that forces are transferred by the exchange of particles called bosons. The boson for the electromagnetic force is the photon. The weak force is transferred by a particle called W. Glashow, Weinberg, and Salam hypothesized the existence of a second boson for the weak force, that is, a second type of particle that carries the weak force, which they called Z. This hypothesized Z would be a sort of middle ground between the photon and W—more like the W in some respects and more like the photon in others. 85
