Historically neurosurgeons were taken to be better dealing with minute details, i.e., using microscope / loupes for surgery like decompression and discectomies and spine surgeons (orthopedics) in bony work like fusions and deformity correction.
This behavior relates to Charles Law of Gases (Gay-Lussac's Law also applies in terms of pressure changes in a rigid container). You may have noticed that car tires and balloons shrink in cold weather. This is due to the molecular motion of gas particles. The gas particles slow down as temperature decreases. This, in turn, decreases their force exerted on the container walls and surrounding particles. The reverse is also true if temperature is increased. Youtube has a 90 minute TV special that relates temperature and absolute zero to the behavior of matter.
Decreasing the volume for an ideal gas at constant temperature and mol always increases the pressure of the gas in the container. However, in this case the pressure exerted when the volume is 4.84 L is exactly equal to the equilibrium vapor pressure of liquid CS2. Any volume decrease will cause the pressure of the vapor to increase. But since the pressure can not exceed the equilibrium vapor pressure decreasing the volume will cause condensation of the vapor to occur. Decreasing the
