The paper presents three simple acoustic experiments carried out using a smartphone and some objects available in any kitchen. […]
The transit times of an air-track trolley are measured with an uncertainty of about 10 micro-s with a Commodore C64 computer connected to expressly built optical sensors. We describe the hardware and software of this cheap and simple device and we report some experimental results. […]
After an introduction on the shape and function of the cornea, this paper describes some applications of infrared and ultraviolet lasers in eye surgery for correcting its curvature and for treating some diseases of the retina. […]
In this paper we present and discuss some of the results on the calibration of the V-Scope data-acquisition system. In particular we evaluate the total uncertainty in V-Scope based measures. Analyzing by V-Scope measurments the dynamic of a simple and double pendulum we show for the last the first space phases boundary of non linear resonances. […]
Some comments to the paper “Un adattatore di tensione fra lo standard americano e quello europeo” are here presented. A more detailed analysis in terms of complex impedances is worked out, and some suggestions for a safer handling of the device are given. […]
