Articoli rivista
Anno XL - n.1 - gennaio/marzo 2007 Perché aspettare dieci minuti per misurare la febbre?
How long must we wait in order to measure our body temperature? A simple experiment allows to apply mathematical techniques while discussing thermodynamics, half-time, time constant. […]
Anno XL - n.4 - ottobre/dicembre 2007 Perché e come studiare fisica
An open letter to secondary school students in which they are explained why studying physics is worthwhile and are given many suggestions on how to do it effectively. […]
Anno XL - n.2 - aprile/giugno 2007 Perché il ghiaccio è scivoloso?
In 1859 Michael Faraday postulated that a thin film of liquid covers the surface of ice – even at temperatures well below freezing. Neglected for nearly a century, the dynamics of ice surfaces has now grown into an active research topic. […]
Anno XLIV - n.2 - aprile/giugno 2011 Perché la bicicletta è vantaggiosa?
Body energy transfers while walking and cycling are analysed and compared, showing why riding a bicycle is energetically more efficient than walking. […]
Anno XLVIII - n.2 - aprile/giugno 2015 Perché la Terra è sferica, o quasi?
The shape of some astronomical bodies of different size is taken into consideration and qualitatively explained on a gravitational-electromagnetic interaction ground. […]
Anno XLII - n.1 - gennaio/marzo 2009 Perché studiare fisica e matematica?
Why should pupils who do not wish to become scientists study physics and mathematics in school and how should such knowledge be useful to those who will? Should these subjects only promote rigour and rationality? The author claims that the teacher should also transmit their elusive beauty and importance apart from practical applications. […]
Anno XXXVI - n.1 - gennaio/marzo 2003 Pesare l’aria
A direct simple method for measuring the specific gravity of air is described. The method is based on a new idea for measuring the pressure of air, compressed into a plastic bottle by means of a common bicycle pump. […]
