SUMMARY
The discussion centers on calculating the temperature at which a steel ball bearing, tightly fitting inside a 1.0 cm Pyrex cube at 390K, will have a clearance of 0.90 pico meters. The coefficient of linear expansion for Pyrex is given as 3.2e-6, while the user seeks to determine the delta L necessary for solving the final temperature. The comparison of the expansion coefficients between Pyrex and steel is also a critical factor in this calculation.
