- Vícha V.: Detecting neutrons using MX-10, Fair 25, Praha 2020
Particle 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.
- Vícha V., Formánek P.: Heat pack, Fair 11, Olomouc 2006
It is possible for some substances to stay in a liquid state at temperatures and pressures below their triple point values. Crystallization in such a state releases its internal energy in the form of heat. Simple measurements concerning this phenomenon can be conducted with a heat pack (Fire Bag)
- Vícha V.: Mystery of Cape Agulhas, Fair 23, České Budějovice 2018
Which physics experiments yield different results on northern and southern hemisphere? The paper describes several experiments conducted (or observed) in Cape Town and surroundings that relate to Sun’s apparent movement, seasons of the year, behaviour of the compass and natural background radiation.
- Vícha V.: Square bubbles, Fair 24, Hradec Králové 2019
A bubble blown from a small bubble blower takes shape of a perfect sphere. However, in this paper we will focus on the shape of square bubbles. Using graph theory, we will investigate whether square bubbles respect minimum surface.
- Vícha V.: The Propeller in Lab Exercises, Fair 8, České Budějovice 2003
Three ideas for laboratory exercises (Rotation movement, Propeller and a monitor, Draw force of a propeller) and one problematic experimental task (Propeller as a balance wheel) with a simple propeller.
- Vícha V.: Utilization of a microphone for measurements in mechanics, Fair 9, Brno 2004
Two laboratory exercises with a microphone connected to a sound blaster which is used for an accurate measurement of short intervals.
