- Bochníček Z.: Up to the skies, Fair 24, Hradec Králové 2019The paper is dedicated to origination of aerodynamic lift and its explanation using Newton’s laws of motion. This explanation prevents hardships and pitfalls connected to usage of Bernoulli’s equation. Another part describes the flight of birds and insects. Comments on the reasons behind differences between small and big flyers are included into the description of insect flight.
- Konečný P.: Some experiments with thermosensitive films, Fair 13, Plzeň 2008This contribution deals with a utilization of reverse thermosensitive foils for detection of temperature changes in experiments demonstrating adiabatic compression or expansion of gas. A demonstration of the 3rd Newton’s law of action and reaction in mechanics of fluid is also included.
- Polák Z.: Simple Experiments, Fair 7, Praha 2002A few of simple experiments which can be used either as a demonstration during teaching or as a laboratory work (weighing on a sheet of paper, flexible centre impact, interconversion of electrical and mechanical energy, model of a turbine, Foucault currents, alcohol vapour rocket).
