We use methods of differential astrometry to construct a small field inertial reference frame stable at the micro-arcsecond level. Such a high level of astrometric precision can be expected with the ...
This PSSC film made in 1960 is one of the finest physics films ever made. All students should see it at some point in their studies. See the article '"Frames of Reference" revisited' by Alistair Steyn ...
In this article we describe how MEMS inertial sensors, e.g., gyroscopes and accelerometers, can help someone or something to overcome spatial disorientation. We explain how external forces and ...
