Two myths about special relativity
Misconceptions about special relativity theory are common and pernicious. I address two such misconceptions: the low-speed behavior of the Lorentz transformation and the meaning of the phrase, "t...

Proportional feedback control of chaos in a simple electronic oscillator
We demonstrate the control of chaos in a nonlinear circuit constructed from readily available electronic components. Control is achieved using recursive proportional feedback, which is applicable to c...

The detection of gravitational radiation raises some subtle issues concerning the coordinate invariance of general relativity. This paper explains these issues and their resolution by using an analogy with the Aharonov-Bohm effect of quantum mechanics.
