- Bochníček Z.: Falling spring, Fair 25, Praha 2020The paper describes two experiments concerning free fall of systems combining elastic and inertial mass. The described experiments represent two extreme situations: 1) elastic mass is negligible, 2) all the falling mass is elastic.
- Dvořák L.: How to weigh using ammeter and voltmeter or Make your own (almost) Kibble scales, Fair 25, Praha 2020The paper describes two experiments concerning free fall of systems combining elastic and inertial mass. The described experiments represent two extreme situations: 1) elastic mass is negligible, 2) all the falling mass is elastic.
- Jandus J.: LEGO LIGO, Fair 25, Praha 2020Those familiar with a term interferometer tend to imagine a complex and very precise apparatus that creates peculiar light patterns. The paper tries to show not only how interferometer itself works but also how to make it yourself be it at home or at school.
- Konečný P.: Magnus effect, Fair 25, Praha 2020In this paper, an apparatus is described that was constructed with a goal to demonstrate and compare Magnus effect to other means of influencing boundary layer, like suction, or surface structure, a so called turbulator.
- Polák Z.: Thermocouple as a permanent physics experiment, Fair 25, Praha 2020The following topics are discussed in this paper: Thermocouple and its place in lessons, manufacturing a metal thermocouple in school conditions, thermocouple thermometer, detection of thermocouple’s small voltages, magnetic field of thermoelectric current, thermoelectric generator as a source of voltage, thermoelectric motor powered by heat from a candle.
- Vícha V.: Detecting neutrons using MX-10, Fair 25, Praha 2020Particle detector MX-10 may serve as a neutron detector when supplemented by a convertor. The paper deals specifically with neutron experiments with direct connection to e.g. nuclear reactor control.
