form $\tau(T)=\exp (A/(T-T_o))$. The inset of Figure \[fig:glass\_lin\_susc\] shows that the data collapse onto a single curve with $A=0.75$, $T_o=0.15$. (The data could not be fitted using $\tau (T)=A(T-T_o)^{\gamma}$ as suggested by simple mode coupling theories [@Gotze92].) Notice that $T_o$ lies below the Vogel–Fulcher temperature $T_{VF}=0.21$ and the MCT critical temperature $T_{C}=0.303$ deduced by fitting the temperature dependence of the relaxation times. This scaling suggests that $\chi_{l}$ becomes a step function for infinite $t_M$ and that the drop in the compressibility would become a discontinuity at infinitely long times. This abrupt drop is consistent with a sudden arrest of the motion of the particles in the liquid which is the kinetic view of the glass transition. The abrupt drop also appears to be in agreement with Mezard and Parisi’s proposal that the glass transition is a first order phase transition with a jump in the specific heat [@Mezard99; @Parisi97b]. Indeed the temperature at which $\chi_{l}$ drops agrees with the temperature of the peak in the specific heat shown in Figure \[fig:spht\_8\_time\]. The specific heat provides an independent check of the glass transition temperature. However, the drop in $\chi_l$ and the specific heat peak are due to the system falling out
