Thinking in Physics (eBook)

Laurence Viennot is emeritus professor at the Université Denis Diderot (Paris 7) and contributed to the creation of the LDPES (Laboratoire de Didactique de la Physique dans l'Enseignement Supérieur) laboratory, now part of the Laboratoire André Revuz. She has for a long time been responsible for the Master's course in science teaching, but devotes herself equally to training physics instructors. Her books and publications are recognised worldwide as sources of reference (Teaching Physics, Enquête sur le concept de causalité, etc.). Previous books:VIENNOT L. 1979.

Part I Acquiring reasoning skills: words, images and functions.- Some tools essential for comprehension.- Words we have to understand.- The image: is it really doing its job?.- Graphs and functions.- Some surprising invariances.- Introduction.- The speed of light in vacuo.- Propagation of mechanical signals.- Coefficients of friction.- When mass doesn't count.- The mirror.- The power and non-obviousness of invariance.- Analysis of functional dependence: a powerful tool.- Numerical or functional?.- Even before values: the form of the relationship.- Keeping an eye on a causal reading of relations.- Some factors not apparent in a relation between quantities, by no means always trivial.- Functional dependencies and graphs: an example in geometrical optics.- Neglected treasures, and some hazards highlighted.- Putting into practice.- Introduction.- The field of a mirror.- Deflection of a charged particle by a magnetic field.- Sliding on an inclined plane.- The slide projector.- Flotation between two immiscible liquids.- Part II Physics: linking factors.- Links between phenomena in terms of type of functional dependence.- Introduction.- Delayed signals: from stars to bats.- Graphical version of the Doppler effect.- Even more links? Doppler and Römer.- Investing?.- Links between different approaches to the same phenomenon.- A hot air balloon for teaching.- A ritual colluding with inconsistency.- A very unusual linkage.- Some evidence of intellectual satisfaction.- Yet more links? Weight and gas pressure.- The benefits of changes of scale in analysis.- Part III Simplicity: ruin or triumph of consistency?.- Simple experiments: how to optimise their use.- Is simplicity relevant?.- Archimedes' weighing machine.- The upside-down glass.- The upside-down test-tube.- Beyond the ritual.- Echo-explanations and linear causal reasoning.- When simple experiment challenges simplistic reasoning.- The "Lovemeter".- Final remarks.- Popularising physics: what place for reasoned argument?.- Mission essential, mission impossible?.- Reason and rigour: some critical points.- A tendency among non-specialists: liking stories.- Authors (as teachers): tendency towards the "echo-explanation".- A real margin for manoeuvre.
