You see in my experimental determination of the location of the accelerometer in an iPod, I used two different iPhone apps. Let me briefly mention some of the free iPhone apps that give you ...

AN absolute determination of the acceleration due to gravity at a site in the National Physical Laboratory has recently been completed. It is the first to be made by timing the symmetrical up-and-down ...

In a dielectric laser accelerator, the large-amplitude fields responsible for the accelerating force are provided by a laser pulse. Of particular interest are lasers that operate in the optical or ...

With the development of satellite miniaturization, intelligence, and clustering, a single satellite platform can no longer support high-power detection equipment. Monocular angle-only cameras have ...
