Big trouble about physics teaching in Italy. Four years ago the ministry of education introduced an examination on physics (writing session) in the scientific high school but lots of maths teachers (teaching physics!) oppose the initiative. Three years later the physics exam can’t be given mainly because of the strong opposition of teachers. The main […]

Amazing coincidences!
In the picture of this post you can see a comparison between two spectrograms of a signal detected at the same time at two different spots at about 150 km distance from each other: the antennae were placed in Guidizzolo (upper diagram) and La Spezia (lower diagram). A spectrogram is a diagram where colors describe […]

Da piccolo Kirk era esile, molto magro. Mangiava poco. La mamma provava un forte dispiacere nel vederlo così debole. A volte faceva portare fuori la cucina economica con tanto di bombola del gas, dietro casa, davanti alla palude. Voleva far sentire il gracidare delle rane al suo bambino.

Laser perturbation by directional signals
Michele Zanoni Laser light perturbation by directional signals Abstract Similar and coincidental signals at a particular frequency were recorded simultaneously from two or three optical sensors piloted by a laser diode at distances up to hundreds of kilometers. Some of the signal’s forms repeat at approximately the same time over the course of a two […]
