A "vertical variation of modern versions of the Michelson-Morley experiment (MMX) with one arm pointed in the vertical direction" experiment has been performed. Watch the following video starting at 0:45. http://youtube.com/watch?v=s9ITt44-EHE "Imagine the Earth as if it were immersed in honey," says Francis Everitt of Stanford University in California, ...

Measuring dead-time (or other hardware efficiencies) is a non-trivial proposition, and there is no completely general solution. The answer that John gives in the comments ($\tau \times \text{number of events}$) is the best case: a system with few interconnections and no "extensible" contributions to the dead time. "Extensible" describes a system where ...

So my question is actually twofold: how did people manage to discover them more than 100 years ago (historically), Historically there are many different ways people discovered different elements, and many ingenious ways of proving that they were actually elementary. One of the most useful and revolutionary was the discovery of Electrochemistry. Where ...

I just realized what the problem is. It actually doesn't have anything to do with the detector. When working in vacuum systems you have to worry about the dielectric breakdown of the air as the pressure is reduced. It turns out that the breakdown voltage hits a minimum around $\sim 1$ Torr depending on the species of the gas (see the curves below). This ...
