The alti- tude of the peak of Mount Whitney (4,460 meters) is some- what less than that of Mount Blanc (4,810 meters), and Lone Pine Camp (1,184 meters) is a little higher than Chamonix (1,040 meters); ...
No improvement is affected by this method, which gives alto- gether too little absorption in the ultra-violet, yet there can be no doubt that these valuable measures are capable of yielding improved results ...

The data marginally prefer constant \(d\alpha/dt\) rather than constant \(\Delta\alpha/\alpha\). ...
Until recently, the most reliable technique was the alkali doublet (AD) method where the measured doublet separation probes variations in the fine-structure constant, \(\alpha \equiv e^2/\hbar c\). ...
However, varying meter rules and/or varying clocks are equally valid conclusions. ...

A novel system to measure the time constant of microbolometer cameras per-pixel to create a 2-D time constant map is presented. ...
Detailed simulations are run for a broad range of variables and values to demonstrate the usefulness of the system in extracting even extremely fast time constants with high accuracy and repeatability. ...
Our system, which is laid out fully in Section II-B, improves upon existing reported systems in key ways, enabling perpixel results to be calculated for nearly arbitrarily fast time constants. ...
