Momentum conservation (or Newton’s third law) ensures two-way or bidirectional coupling for typical media like guitar strings and spring mattresses. One-way or unidirectional coupling enables the propagation of solitary waves or solitons with diverse behaviors in otherwise dissipative media, but at the expense of both momentum and energy conservation. Nevertheless, one-way media are possible, provided…

Wind is free and ubiquitous and can be harnessed in multiple ways. We recently published an article in the Physical Review demonstrating mechanical stochastic resonance in a tabletop experiment that harvests wind energy to amplify weak periodic signals detected via the movement of an inverted pendulum. Unlike earlier mechanical stochastic resonance experiments, where noise was added via…

I recently ascended to Czar of Physics. (Oops — I mistyped Chair and it autocompleted to Czar!) It’s not my first year as Czar, but this time, during the handover from the previous Czar, I inherited a small cardboard box. Inside I found a stack of old Wooster ΣΠΣ membership cards. (ΣΠΣ is Greek for SPS and signifies…
